TL;DR — Ngā Mea Me Mōhio Koe
- Ngā poraka whakamutunga pae pahi DIN reriwe kua whakatauria he 1000V/200A whakahaere i te tohatoha hiko matua i roto i ngā panera ahumahi — e tuku ana ki te 200A mā te kōwae kiato kotahi.
- E ai ki te IEC 60947-7-1 me te UL 1059, kua whakamanahia ēnei poraka mō ngā ara iahiko tae atu ki te 1000V AC (1500V DC), me ngā awhe waea mai i te 6mm² ki te 70mm² (AWG 10 ki te 2/0).
- Ko te kōwhiringa rauemi o te pae pahi te mea nui rawa atu hei wehewehe i te mahi — he pai ake te parahi hikohiko (99.9% te kawe hiko IACS) i ngā pae paera mā te 40% i roto i te whakamararatanga wera i te iahiko kua whakatauria.
- Hei kaihanga tika, ka tukuna e mātou he penapena utu 30-50% ki te whakataurite ki ngā waitohu Pākehā, me te tuku anō hoki i ngā tiwhikete IEC/UL ōrite me ngā wā arahi whakaputa tere ake.
- Mō te mahi tonu 200A, me tohu tonu ngā pae paera parahi whakakikoruatia ki te tine me te iti rawa o te wāhanga whakawhiti o te 16mm² — mā tēnei ka ārai i te rerenga wera i te paepae whakahekenga tonu o te 80%.
He aha tonu te poraka whakamutunga o te DIN Rail Busbar?
He hononga hiko ā-pūrua te poraka pahi tereina DIN i hangaia mō te tohatoha hiko — ehara i te waea tohu, ehara i te ara iahiko whakahaere, engari ko te whakahaere mana tūturuKa taunga ki runga i tētahi rēra DIN paerewa TS-35 (35mm te whānui) ā, ka whakamahia he pae parahi whakauru hei tohatoha i te mana matua e haere mai ana ki ngā ara iahiko peka maha e puta atu ana. Ko te āhuatanga matua e wehewehe ana i te poraka pito o te pae pahi mai i te poraka whāngai paerewa ko te reriwe arataki tiritahi: kotahi te arataki nui e haere mai ana ka whakakaha i te pae pahi parahi, ā, ko ia tūranga pito i taua pae pahi ka uru ki te pūmanawa ōrite.
I roto i tā mātou wheketere, ka hangaia e mātou ēnei poraka i roto i ngā whirihoranga mai i te ara-2 ki te ara-20 — ko te tikanga ka taea e te whāngai matua kotahi te whakakaha i te 20 ara iahiko peka takitahi mai i te tapuwae kotahi o te reera DIN kiato. He mea nui rawa tēnei i roto i te hanganga panera o te ao tūturu nā te mea ka whakakorea te hiahia mō ngā poraka tohatoha hiko motuhake, ka whakaitihia te wā waea o te papaaho mā te 40-60% pea ki te whakataurite ki ngā otinga pekepeke takitahi mai i te pito ki te pito..
Te Mārama ki ngā Whakatauranga 1000V me 200A: Te Tikanga Tuturu o ngā Tau
Ina kōrero tātou mō te "whakatauranga 1000V" me te "kaha 200A," e kōrero ana tātou mō ngā tawhā ahotea hiko e rua e tino rerekē ana — ā, ko te whakapoauau i a rāua he hapa kua kite ahau i ngā kaihangarau e mahi ana i ngā wā maha rawa i roto i aku tau 15 i roto i tēnei umanga.
Te Whakatauranga Ngaohiko (1000V): He Wero Ārai
Ko te whakatauranga 1000V e pā ana ki te pakari o te whakamarumaru, ehara i te kaha o te ara iahiko. Mō ia IEC 60947-7-1, me pupuri e ngā poraka pito mō ngā ara iahiko tae atu ki te 1000V AC te tawhiti ngoki iti rawa o te 8mm me te tawhiti ātea o te 5.5mm i waenga i ngā pou tata — ā, ka inehia ēnei tawhiti i te puranga manawanui kino rawa atu. Nā te mea me tu atu te rauemi o te whare (he nairona PA66 te nuinga me te muka karāhe 30% te whakakaha) i te ngaohiko hiko kua whakatauria me te kore e whai, e pakaru rānei, ka whakamahia e mātou te polyamide ātete-mumura UL94 V-0 me te taupū aroturuki whakatairite (CTI) neke atu i te 400V.
I roto i tā mātou raina whakaputa, ka whakamatautauria te kaha hiko 2200V AC mō ia poraka 1000V mō te 60 hēkona — he nui atu i te rua o te ngaohiko kua whakatauria, nā te mea Me tu tonu te whakamarumaru i ngā ngaohiko tere e puta mai ana i ngā taiao ahumahi tūturu i ia rā mai i ngā tīmatanga motuka, te whakawhiti whakapā, me ngā mahi a te peeke pūnga..
Whakatauranga o Nāianei (200A): He Raru Whakahaere Wera
Kāore anō kia mārama te whakatauranga 200A. He whakatauranga wera tēnei, ehara i te rohe ā-tinana mō te rere o te irahiko. I te iahiko tonu 200A, ka puta te wera tata ki te 12-15 watts i roto i te pae parahi 16mm² mō ia mita, ā, i roto i te papa whakahaere hiri i te pāmahana taiao 40°C, me haere taua wera ki tētahi wāhi. Koia te take Ka inehia tonutia te reiti o te iahiko o te poraka pito i tētahi pāmahana taiao motuhake (ko te tikanga he 40°C ia i runga i te IEC 60947-7-1) ā, ka whakaarohia he kawe hau kore utu huri noa i te poraka.
Pūtaiao Rauemi Busbar: He aha te Hiranga o te Parahi i tō Whakaaro
E hiahia ana ahau kia kōrero pūmau i konei: Ko te rauemi o te pae pahi i roto i te poraka taunga te mea tino nui e whakatau ana i tōna mahi i te ao tūturu — ā, koinei anō hoki te wāhi e whakaiti ana i ngā utu a ngā kaihanga.
E toru ngā rauemi pae pahi e kitea whānuitia ana i te mākete, ā, he rerekē rawa te mahi a ēnei rauemi:
| Rauemi Paepae | Te Aroturukitanga (% IACS) | Te Arahi Wera (W/m·K) | Kaha Kume (MPa) | Tāurangi Utu |
|---|---|---|---|---|
| Parahi Hikohiko (C11000) | 99.9% | 391 | 220-250 | 100 |
| Parahi (C26000) | 28% | 120 | 300-400 | 55 |
| Parahi Whakakikorua-Tīni | 99.5% (mata) | 385 | 220-250 | 115 |
Ko te parahi hiko C11000 anake tā mātou e whakamahi ana mō ā mātou poraka whakamutunga pae pahi katoa he 200A te whakatauranga. He aha? Nā te mea Ko ngā pae parāhi parahi e rere ana i te 200A ka eke ki te pāmahana mata 25-30°C teitei ake i ngā pae parāhi parahi ōrite — ā, ko taua rerekētanga pāmahana ka puta he iti ake te pēhanga whakapā i ngā pito tīwiri, he piki ake ngā tere waikura, ā, he poto ake te roa o te ora o te hua. Ko te rerekētanga utu i waenga i te parahi me te parahi mō tētahi poraka pae pahi 10-tūnga noa he tata ki te $0.80-1.20 te utu rauemi mata — ehara tēnā i te mea e pai ana ahau ki te whakaae.
Hangarau Āputa Waea me te Hononga: Te Whakataurite i ngā Kaiārahi ki te Pūngao
Ko te whānuitanga o te urunga waea o te poraka pito pahi 200A kei waenganui i te 6mm² (AWG 10) me te 70mm² (AWG 2/0) i te taha whakauru matua, ā, ko ngā pito peka e whakaae ana ki te 1.5mm² ki te 16mm² (AWG 16 ki te 6). Ehara i te mea tūpono noa tēnei whānuitanga o te mana — e whakaata ana i te mooni hiko o te tohatoha hiko: ko te whāngai matua e kawe ana i te 200A katoa (nō reira te mōrahi 70mm²), ko ngā ara iahiko peka takitahi ka kukume mai i te 2A ki te 63A (nō reira te awhe 1.5-16mm²).
E toru ngā hangarau hononga e tukuna ana e mātou, he rerekē ngā painga o ia hangarau:
Hononga Rawhi Tīwiri (tō mātou hoiho mahi): Ka pēhia te ara iahiko e te tīwiri maitai ki te pae parahi, ka hangaia he hononga matao ātete-hau i te atanga whakapā. Koinei tonu te hononga pono rawa atu mō ngā tono au-tiketike nā te mea ka tukuna e te tīwiri he 2.0-3.5 Nm o te taipana — he nui hei whakapēke paku i te ara iahiko parahi, hei hanga hoki i tētahi here whakarewa e ātete ana ki te wetewete i puta mai i te wiri. Ko te ngoikoretanga? E 15-20 hēkona te roa o te tāutanga mō ia waea.
Hononga Puna Pana-roto (tō mātou tere rawa): Ka mau te ara iahiko i te rawhi puna maitai kore waikura, kāore he taputapu. E toru hēkona te roa o te tāutanga. Heoi anō — ā, he mea nui tēnei — ko ngā hononga pana-whakauru e herea ana ki te rahi mōrahi o te ara iahiko 16mm² i roto i te hangarau o nāianei, ko te tikanga kāore e taea e rātou te whakahaere i te ara iahiko matua 70mm² katoa i runga i te poraka 200A. Mō te whāngai matua, me hiahia tonu koe ki te hononga tīwiri, ki te hononga pou rānei.
Hononga Poro/Pūtu (tō mātou mea taumaha rawa): Ka taea te whakamahi i tētahi porowhita miro me te nati hexagonal hei whakapiko i ngā pito mowhiti ki te waea. Koinei anake te momo hononga e pono ana te whakamahi i ngā ara iahiko neke atu i te 35mm², ā, koinei te mea e tohua ana e mātou mō ngā pito whakauru matua 150A me te 200A katoa hei paerewa.
Ngā Tiwhikete me ngā Whakatutukitanga Paerewa: Ngā Mea ka Tirohia e tō Kaitirotiro
Mena he akoranga kotahi i akohia e au i te ara uaua i ngā tau tōmua o tā mātou mahi hangahanga, koia tēnei: ehara ngā tiwhikete i te mea whiriwhiri noa iho — koinei te arai iti rawa ki te whakaurunga mō tētahi hokohoko ahumahi nui. Anei ngā mea me manatoko e koe i runga i tētahi pepa whakatakotoranga poraka pūmau DIN rail:
IEC 60947-7-1 — Koinei te paerewa ā-ao matua mō ngā poraka taunga e whakamahia ana i roto i ngā huihuinga taputapu whakawhiti ngaohiko iti me ngā taputapu whakahaere. E tautuhi ana i te ngaohiko whakatauranga (≤1000V AC), te iahiko whakatauranga, ngā kaha whakawhiti-wāhanga, me te — he mea nui — ngā tukanga whakamātautau whakatauranga iahiko poto (SCCR)Mō ia te whakatikatika hou ki te IEC 60947-7-1, me whakapuaki mārama e ngā poraka taunga tō rātou uara SCCR, me hono tahi me ngā taputapu tiaki o runga.
UL 1059 — Ko te rite o Amerika Te Raki, e kapi ana i ngā poraka taunga tae atu ki te 1500V. He tino pakari ake te whakamātautau UL 1059 i te IEC i roto i ētahi wāhanga matua: me whakamātautau ātete hikohiko i te 2× ngaohiko whakatauranga + 1000V (me te ngaohiko whakatauranga 2× a IEC), ā, me whakamātautau huringa wera i te iahiko whakatauranga mō te 50 huringa (me te whakamātautau pikinga pāmahana pumau a IEC). Mō ia UL 1059 Putanga 6-2024, ka tāpirihia e te whakahoutanga hou ngā whakaritenga whakarei ake mō ngā poraka whakamutunga o te arai tiaki.
Ko tā mātou putea tiwhikete hei kaihanga poraka tauranga pahi tereina din kei roto: Tohu CE (te tutuki i ngā whakaritenga a te EU), rārangi UL (kei te wātea te kōnae mēnā ka tonoa), whakahaere kounga ISO 9001:2008, whakamātautau tuatoru a te SGS, tutuki i te whakaritenga a te RoHS, me te whakapuakitanga REACH. Kei roto i ia uta he tiwhikete tutuki me ngā tau puranga ka taea te whai.
He aha i whiriwhiri ai koe i tētahi Kaihanga Poraka Whakamutunga Pahi DIN Rail Haina?
Ka aro tika atu ahau ki tēnei pātai nā te mea ka pātai mai ngā tīma hokohoko i tēnei ki a mātou i ia wiki. Kua tino rerekē te ahumahi wāhanga hiko i roto i te tekau tau kua pahure ake nei. Nā te kaha hanga o Haina i whakawhāiti te rerekētanga kounga ki ngā kaihanga o Ūropi me Amerika — me te pupuri tonu i te painga utu 30-50% e ahu mai ana i te hanga poutū whakauru, ehara i te mea nā te tapahi i ngā rauemi, i te whakamātautau rānei.
Anei te tikanga o te whakaurunga poutū i roto i te mahi i roto i tō mātou whare: Ka ringihia e mātou ā mātou ake pokepokea ai werohanga i roto i te whare. Ka tāia e mātou ā mātou ake pae parahi mai i te rīpene parahi C11000 kua whakamanahia i ahu mai i Jiangxi Copper (tetahi o ngā kaihanga parahi nui rawa atu o te ao). Ka whakahaerehia e mātou ā mātou ake raina huihuinga aunoa. Ā, kei a mātou anō te taiwhanga whakamātautau o roto, he taputapu whakamātautau hiko-kore, he mita moroiti-ohm, he kāmera whakaahua wera, me te rūma whakamātautau tere-ora 500-hāora.
Mā tēnei whakaurunga poutū ka whakakorea ngā paparanga e toru o te tāpiringa utu — te kaituku rauemi mata, te kaiwhakarato wāhanga iti, me te kaiwhakaemi kirimana — e whakaurua ana ki roto i te utu o ngā poraka taunga waitohu o te Hauāuru (me kī atu ahau, kei te piki haere te hanga i Haina, engari he rerekē te tapanga).
Mō ngā OEM me ngā kaihanga panera e rapu ana mai i tā mātou wheketere tika, ko te whakamaoritanga o te ōhanga ki:
- Te whakaiti i te utu mō ia wae o te 35-50% me ngā poraka whakamutunga o te pae pahi Weidmüller, Phoenix Contact rānei, he ōrite ngā whakatakotoranga.
- Ngā wā ārahi 2-4 wiki mō ngā hua putumōhio paerewa, whakaritea ki ngā wiki 8-12 e rite ana ki ngā kaihanga o Ūropi (he rerekētanga kua whakaora i te neke atu i te kotahi o ā mātou kiritaki mai i ngā whiu whakaroa kaupapa).
- Te waitohu OEM me ngā kōwhiringa tae/whare ritenga kāore he utu taputapu tāpiri mō ngā rahinga neke atu i te 5,000 waeine — nā te mea nō mātou tō mātou toa pokepoke.
Me pēhea te whiriwhiri i te poraka whakamutunga pahi DIN Rail tika: He tukanga 5-taahiraa
I muri i te 15 tau o te whakautu i ngā pātai hangarau, kua wehewehea e au te tukanga kōwhiringa kia rima ngā whakataunga raupapa. Pekehia tētahi taahiraa, ā, ka nui rawa te whakapaunga moni ki ngā taputapu kua tohua rawatia, ka tāuta rānei i tētahi poraka taura ka noho hei mōrearea ahi.
Hipanga 1: Whakatauhia tō Auaha Tonu Mōrahi
Kaua e whakamahia te whakatauranga o te whati ara iahiko hei pūtake mōu i nāianei. Inehia, tātaihia rānei te iahiko kawenga tonu i raro i ngā āhuatanga kino rawa atu. Whakamahia te Te ture whakahekenga tonu a NEC 80%Ki te 160A te kaha e tōia tonutia ana e tō kawenga, me whai poraka tauranga koe kia 200A te iti rawa. Nā te mea kāore he whakamatao hohe o ngā poraka pito, ko te huarahi anake hei whakamarara i te wera I²R ko te horahanga mata me te kawe hiko — ā, ko te whakaiti i te rahi o te poraka ka puta he paheketanga wera tuturu o te whare polyamide.
Hipanga 2: Manatokohia te Akomanga Ngaohiko
Mō ngā pūnaha toru-wāhanga 480V (he mea noa i Amerika Te Raki), he rawaka te poraka 600V. Mō ngā pūnaha 690V (he mea noa i ngā tono ahumahi o Ūropi) me ngā whakaurunga pūngao rā 1000V, me whiwhi koe i te whakatauranga 1000V katoa. Me manatoko tonu te ngaohiko ātete hiko (Uimp) me te ngaohiko whakamarumaru kua whakatauria (Ui) — ko te ātete hiko te mea e tiaki ana i ngā whakawhiti me ngā ngaru whakawhiti e puta mai ana i te uira.
Hipanga 3: Tatauhia ō Porowhita Peka
Tatauhia ia ara iahiko e puta atu ana me whakamahi ki te pūmanawa matua o te pae pahi. Tāpirihia he 20% o te kaha tāpiri mō te whakawhānui ā muri ake nei — nā te mea ko te tāpiri i ngā tūranga i muri mai me momotu me te hono anō i te waea o te poraka katoa, he nui rawa atu te utu i te tāuta i tētahi poraka nui ake i te tīmatanga.
Hipanga 4: Whakatauritehia ngā Rahi Waea
Manatokohia kei te hipokina e te awhe whakaaetia waea o te poraka pūrua tō ara iahiko whāngai matua ME tō ara iahiko peka iti rawa. Ko te hapa kōwhiringa e kitea ana e au ko te tohu i tētahi poraka 200A me te tumanako ka tau he waea peka 1.5mm² — kāore e taea e te nuinga o ngā poraka au-rahi te piri pono ki ngā ara iahiko i raro i te 4mm². I tēnei wā, whakamahia he pine whakaiti, he wīra rānei, engari me whai whakaaro anō ki te wā huihuinga tāpiri.
Hipanga 5: Manatokohia te Whakaritenga SCCR
Tonoa te tiwhikete whakamātautau SCCR mai i tō kaihanga. Me teitei ake te uara SCCR i te iahiko hapa e wātea ana i te wāhi tāutanga. Mō ngā tono tohatoha hiko matua, ko te SCCR o te 25kA neke atu rānei i te ngaohiko kua whakatauria te iti rawa mahi — ki te iti iho i tēnā, ka noho tō poraka pūmau hei whakapūmau i roto i tō pūnaha, engari ehara i te mea i roto i te huarahi whakahaeretia.
Ngā Tikanga Pai o te Tāutanga: Ngā Mea Kāore e Kōrerotia ana e te Pepa Raraunga ki a Koe
Ka whakamōhiotia koe e ngā pepa raraunga i ngā uara taipana me te roa o ngā rīpene waea. Kāore rātou e kōrero ki a koe he aha te hē o te mahi i te mara. Anei ngā mea kua akohia e mātou mai i ngā mano tini o ngā taunekeneke tautoko kiritaki:
He mea nui ake te taipana i tō whakaaro — ā, he 10 ngā wā ka nui ake te kitea o te taipana iti i te taipana nui rawa. Ko te pūrua tīwiri kua whakaukia ki te 50% o te taipana kua whakatauria ka whakaatu i te ātete pa 3-5x teitei ake i te whakatakotoranga — ā, i te 200A, ka whakaputahia e taua ātete tāpiri he wera hei whakangawari i te whare PA66 i roto i ngā haora o te mahi tonu. Ka tukuna atu e mātou he tīwiri taipana kua whakatikatikaina mō ia tauira tuku tuatahi nā te mea e mōhio ana mātou he maha ngā toa panera e whakamahi ana i ngā tīwiri ā-ringa kāore anō kia whakatikatikaina.
Kāore e tika ana te whakamahi i te taura i runga ake i te 16mm². Ka horapa haere ngā ara iahiko parahi kua werohia, kāore he taura i raro i te pēhanga — ka pā ētahi aho, ko ētahi kāore. Ka whakaitihia te horahanga pā whai hua mā te 20-30% ki te whakataurite ki tētahi taura kua kōpiko tika, ā, ko te tikanga o tēnei he nui ake te ātete, he nui ake te pāmahana, ā, i te wā kino rawa atu — ka whati te aho i te huringa wera. Kei roto i ngā poraka taunga katoa he 25mm² te rahi, ā, kei roto i ēnei he taura parahi e tutuki ana i ngā whakaritenga DIN 46228.
Me whakapūhaumāota ngā poraka tauranga pahi. He rerekē ki ngā poraka pito whāngai e kawe ana i te iahiko mā te ara kotahi o te ara iahiko, ka kukū ngā poraka pae pahi i te 200A mā te ara kotahi o te ara parahi e rere ana i te roa o te poraka katoa. I roto i tētahi panera kapi tonu, me tāuta ēnei poraka me te āputa hau 10mm te iti rawa i ngā taha katoa — nā te mea ko te wera e whakaputaina ana e te 200A i roto i te pae pahi 16mm² he tata ki te 0.75W mō ia tūranga pūrua, ā, ka whakaputa tonu te poraka 20-tūranga i te 15W.
Ngā Pātai Auau
P: Ka taea e au te whakamahi i te poraka whakamutunga pahi 200A kotahi mō ngā tono AC me DC?
Ae, engari me ētahi whakatūpato nui. Me whakaheke te whakatauranga o te au mō te DC nā te mea kāore ngā pewa DC e tineia i a rātou anō i ngā pūwāhi whakawhiti-kore. E ai ki te IEC 60947-7-1, me whakaheke te whakatauranga o ngā poraka pito e whakamahia ana i roto i ngā ara iahiko DC ki te 80% o tō rātou whakatauranga au AC — nō reira ka noho te poraka AC 200A hei poraka DC 160A. Hei tāpiri, me ōrite te pōraretanga DC puta noa i ngā pito katoa e whakamahi tahi ana i te pae pahi; mā te whakaranu i ngā pōraretanga i runga i te pae pahi kotahi ka puta he poto poto.
P: He aha te rerekētanga i waenga i te poraka taunga pahi me te poraka tohatoha hiko?
Ka whakauruhia te pae pahi ki roto i te whare o te pae pahi, ā, ka mau ki runga i te rēra DIN. Ko te poraka tohatoha hiko (PDB) he taputapu nui ake, motuhake me tētahi pouaka motuhake, ka mau pea ki runga i te rēra DIN, kāore rānei. He nui ake te mātotoru me te māmā ake o te waea o ngā poraka tauranga pahi mō ngā tono tae atu ki te 200A; he pai ake ngā PDB i te 200A, ina kore e whai hua te huarahi whakauru nā te piko o ngā rākau waea me te marara o te wera.
Q: Kia pēhea te roa o te mau o ngā poraka whakamutunga o te pae pahi tereina DIN?
I raro i ngā āhuatanga kua whakatauria (40°C te taiao, ≤80% te kawenga tonu), ko te roanga hoahoa o tētahi poraka pahi parahi kua tāuta tika me te whare PA66 he 20+ tau. Ko te mea e whakawhāiti ana i te ora o te mea he huringa wera tonu — ko te whānui me te whakaheke o te pae parahi (CTE: 17×10⁻⁶/K) ki te whare PA66 (CTE: 80×10⁻⁶/K) ka wetekina haeretia ngā hononga tīwiri puta noa i ngā mano huringa. Mā te whakahou i te taipana ā-tau i te wā o te tiaki kua whakaritea ka roa ake te ora o te ratonga.
P: Ka taea e au te tiki whirihoranga pae pahi ritenga?
Āe. Hei kaihanga pokepoke ā-roto, he mea hanga noa e mātou ngā poraka mutunga pae pahi ritenga me te maha o ngā pou kāore i te paerewa, ngā whakatauranga iahiko whakauru i runga i te pae pahi kotahi, ngā whare tae motuhake mō te waehere ngaohiko, me te tohu/tapanga ritenga. Ka tīmata te iti rawa o ngā ota mō ngā whirihoranga ritenga i te 1,000 waeine, me te utu mō ngā taputapu kei roto i te utu waeine. Whakapā mai ki tā mātou tīma hangarau i sara@nbjguang.com me āu whakaritenga.
Q: He hototahi ngā poraka terminal J-Guang ki ngā taputapu mai i ētahi atu waitohu?
Ka whakamahia e ā mātou poraka tauranga tereina DIN te kōtaha tereina TS-35 paerewa-a-umanga me te mokowā waenga paerewa (ko te tikanga he 6mm, 8mm, 10mm rānei i runga i te raupapa). Ko ngā whīra pito, ngā pereti wehewehe, me ngā rīpene tohu he mea hototahi ki ngā waitohu nui (Weidmüller W-Series, Phoenix Contact UK-Series) nā te mea he paerewa ahumahi ēnei ine — ahakoa e taunaki tonu ana mātou kia manatokohia te hototahitanga ā-mīhini me te tauira i mua i te tuku i ngā ota nui.
He aha i hiahiatia ai a J-Guang mō āu Poraka Whakamutunga Pahi DIN Rail
Mai i te tau 2010 mātou e hanga ana i ngā poraka me ngā hononga i tō mātou whare i Ningbo, Haina — 15 tau mātou e arotahi ana ki tēnei kāwai hua. Ehara mātou i te kamupene hokohoko e ahu mai ana i ngā wheketere tūpono noa iho; ko mātou te wheketere.

Kaihanga Poraka Whakamutunga Pae Pahi DIN Rail: Whakatauranga 1000V me te Kaha 200A mō te Tohatoha Mana Matua
📋 TL;DR — Ngā Mea Me Mōhio Koe
- Ngā poraka whakamutunga pae pahi DIN reriwe kua whakatauria he 1000V/200A whakahaere i te tohatoha hiko matua i roto i ngā panera ahumahi — e tuku ana ki te 200A mā te kōwae kiato kotahi.
- E ai ki te IEC 60947-7-1 me te UL 1059, kua whakamanahia ēnei poraka mō ngā ara iahiko tae atu ki te 1000V AC (1500V DC), me ngā awhe waea mai i te 6mm² ki te 70mm² (AWG 10 ki te 2/0).
- Ko te kōwhiringa rauemi o te pae pahi te mea nui rawa atu hei wehewehe i te mahi — he pai ake te parahi hikohiko (99.9% te kawe hiko IACS) i ngā pae paera mā te 40% i roto i te whakamararatanga wera i te iahiko kua whakatauria.
- Hei kaihanga tika, ka tukuna e mātou he penapena utu 30-50% ki te whakataurite ki ngā waitohu Pākehā, me te tuku anō hoki i ngā tiwhikete IEC/UL ōrite me ngā wā arahi whakaputa tere ake.
- Mō te mahi tonu 200A, me tohu tonu ngā pae paera parahi whakakikoruatia ki te tine me te iti rawa o te wāhanga whakawhiti o te 16mm² — mā tēnei ka ārai i te rerenga wera i te paepae whakahekenga tonu o te 80%.
He aha tonu te poraka whakamutunga o te DIN Rail Busbar?
He hononga hiko ā-pūrua te poraka pahi tereina DIN i hangaia mō te tohatoha hiko — ehara i te waea tohu, ehara i te ara iahiko whakahaere, engari ko te whakahaere mana tūturuKa taunga ki runga i tētahi rēra DIN paerewa TS-35 (35mm te whānui) ā, ka whakamahia he pae parahi whakauru hei tohatoha i te mana matua e haere mai ana ki ngā ara iahiko peka maha e puta atu ana. Ko te āhuatanga matua e wehewehe ana i te poraka pito o te pae pahi mai i te poraka whāngai paerewa ko te reriwe arataki tiritahi: kotahi te arataki nui e haere mai ana ka whakakaha i te pae pahi parahi, ā, ko ia tūranga pito i taua pae pahi ka uru ki te pūmanawa ōrite.
I roto i tā mātou wheketere, ka hangaia e mātou ēnei poraka i roto i ngā whirihoranga mai i te ara-2 ki te ara-20 — ko te tikanga ka taea e te whāngai matua kotahi te whakakaha i te 20 ara iahiko peka takitahi mai i te tapuwae kotahi o te reera DIN kiato. He mea nui rawa tēnei i roto i te hanganga panera o te ao tūturu nā te mea ka whakakorea te hiahia mō ngā poraka tohatoha hiko motuhake, ka whakaitihia te wā waea o te papaaho mā te 40-60% pea ki te whakataurite ki ngā otinga pekepeke takitahi mai i te pito ki te pito..
Te Mārama ki ngā Whakatauranga 1000V me 200A: Te Tikanga Tuturu o ngā Tau
Ina kōrero tātou mō te "whakatauranga 1000V" me te "kaha 200A," e kōrero ana tātou mō ngā tawhā ahotea hiko e rua e tino rerekē ana — ā, ko te whakapoauau i a rāua he hapa kua kite ahau i ngā kaihangarau e mahi ana i ngā wā maha rawa i roto i aku tau 15 i roto i tēnei umanga.
Te Whakatauranga Ngaohiko (1000V): He Wero Ārai
Ko te whakatauranga 1000V e pā ana ki te pakari o te whakamarumaru, ehara i te kaha o te ara iahiko. Mō ia IEC 60947-7-1, me pupuri e ngā poraka pito mō ngā ara iahiko tae atu ki te 1000V AC te tawhiti ngoki iti rawa o te 8mm me te tawhiti ātea o te 5.5mm i waenga i ngā pou tata — ā, ka inehia ēnei tawhiti i te puranga manawanui kino rawa atu. Nā te mea me tu atu te rauemi o te whare (he nairona PA66 te nuinga me te muka karāhe 30% te whakakaha) i te ngaohiko hiko kua whakatauria me te kore e whai, e pakaru rānei, ka whakamahia e mātou te polyamide ātete-mumura UL94 V-0 me te taupū aroturuki whakatairite (CTI) neke atu i te 400V.
I roto i tā mātou raina whakaputa, ka whakamatautauria te kaha hiko 2200V AC mō ia poraka 1000V mō te 60 hēkona — he nui atu i te rua o te ngaohiko kua whakatauria, nā te mea Me tu tonu te whakamarumaru i ngā ngaohiko tere e puta mai ana i ngā taiao ahumahi tūturu i ia rā mai i ngā tīmatanga motuka, te whakawhiti whakapā, me ngā mahi a te peeke pūnga..
Whakatauranga o Nāianei (200A): He Raru Whakahaere Wera
Kāore anō kia mārama te whakatauranga 200A. He whakatauranga wera tēnei, ehara i te rohe ā-tinana mō te rere o te irahiko. I te iahiko tonu 200A, ka puta te wera tata ki te 12-15 watts i roto i te pae parahi 16mm² mō ia mita, ā, i roto i te papa whakahaere hiri i te pāmahana taiao 40°C, me haere taua wera ki tētahi wāhi. Koia te take Ka inehia tonutia te reiti o te iahiko o te poraka pito i tētahi pāmahana taiao motuhake (ko te tikanga he 40°C ia i runga i te IEC 60947-7-1) ā, ka whakaarohia he kawe hau kore utu huri noa i te poraka.
Pūtaiao Rauemi Busbar: He aha te Hiranga o te Parahi i tō Whakaaro
E hiahia ana ahau kia kōrero pūmau i konei: Ko te rauemi o te pae pahi i roto i te poraka taunga te mea tino nui e whakatau ana i tōna mahi i te ao tūturu — ā, koinei anō hoki te wāhi e whakaiti ana i ngā utu a ngā kaihanga.
E toru ngā rauemi pae pahi e kitea whānuitia ana i te mākete, ā, he rerekē rawa te mahi a ēnei rauemi:
| Rauemi Paepae | Te Aroturukitanga (% IACS) | Te Arahi Wera (W/m·K) | Kaha Kume (MPa) | Tāurangi Utu |
|---|---|---|---|---|
| Parahi Hikohiko (C11000) | 99.9% | 391 | 220-250 | 100 |
| Parahi (C26000) | 28% | 120 | 300-400 | 55 |
| Parahi Whakakikorua-Tīni | 99.5% (mata) | 385 | 220-250 | 115 |
Ko te parahi hiko C11000 anake tā mātou e whakamahi ana mō ā mātou poraka whakamutunga pae pahi katoa he 200A te whakatauranga. He aha? Nā te mea Ko ngā pae parāhi parahi e rere ana i te 200A ka eke ki te pāmahana mata 25-30°C teitei ake i ngā pae parāhi parahi ōrite — ā, ko taua rerekētanga pāmahana ka puta he iti ake te pēhanga whakapā i ngā pito tīwiri, he piki ake ngā tere waikura, ā, he poto ake te roa o te ora o te hua. Ko te rerekētanga utu i waenga i te parahi me te parahi mō tētahi poraka pae pahi 10-tūnga noa he tata ki te $0.80-1.20 te utu rauemi mata — ehara tēnā i te mea e pai ana ahau ki te whakaae.
Hangarau Āputa Waea me te Hononga: Te Whakataurite i ngā Kaiārahi ki te Pūngao
Ko te whānuitanga o te urunga waea o te poraka pito pahi 200A kei waenganui i te 6mm² (AWG 10) me te 70mm² (AWG 2/0) i te taha whakauru matua, ā, ko ngā pito peka e whakaae ana ki te 1.5mm² ki te 16mm² (AWG 16 ki te 6). Ehara i te mea tūpono noa tēnei whānuitanga o te mana — e whakaata ana i te mooni hiko o te tohatoha hiko: ko te whāngai matua e kawe ana i te 200A katoa (nō reira te mōrahi 70mm²), ko ngā ara iahiko peka takitahi ka kukume mai i te 2A ki te 63A (nō reira te awhe 1.5-16mm²).
E toru ngā hangarau hononga e tukuna ana e mātou, he rerekē ngā painga o ia hangarau:
Hononga Rawhi Tīwiri (tō mātou hoiho mahi): Ka pēhia te ara iahiko e te tīwiri maitai ki te pae parahi, ka hangaia he hononga matao ātete-hau i te atanga whakapā. Koinei tonu te hononga pono rawa atu mō ngā tono au-tiketike nā te mea ka tukuna e te tīwiri he 2.0-3.5 Nm o te taipana — he nui hei whakapēke paku i te ara iahiko parahi, hei hanga hoki i tētahi here whakarewa e ātete ana ki te wetewete i puta mai i te wiri. Ko te ngoikoretanga? E 15-20 hēkona te roa o te tāutanga mō ia waea.
Hononga Puna Pana-roto (tō mātou tere rawa): Ka mau te ara iahiko i te rawhi puna maitai kore waikura, kāore he taputapu. E toru hēkona te roa o te tāutanga. Heoi anō — ā, he mea nui tēnei — ko ngā hononga pana-whakauru e herea ana ki te rahi mōrahi o te ara iahiko 16mm² i roto i te hangarau o nāianei, ko te tikanga kāore e taea e rātou te whakahaere i te ara iahiko matua 70mm² katoa i runga i te poraka 200A. Mō te whāngai matua, me hiahia tonu koe ki te hononga tīwiri, ki te hononga pou rānei.
Hononga Poro/Pūtu (tō mātou mea taumaha rawa): Ka taea te whakamahi i tētahi porowhita miro me te nati hexagonal hei whakapiko i ngā pito mowhiti ki te waea. Koinei anake te momo hononga e pono ana te whakamahi i ngā ara iahiko neke atu i te 35mm², ā, koinei te mea e tohua ana e mātou mō ngā pito whakauru matua 150A me te 200A katoa hei paerewa.
Ngā Tiwhikete me ngā Whakatutukitanga Paerewa: Ngā Mea ka Tirohia e tō Kaitirotiro
Mena he akoranga kotahi i akohia e au i te ara uaua i ngā tau tōmua o tā mātou mahi hangahanga, koia tēnei: ehara ngā tiwhikete i te mea whiriwhiri noa iho — koinei te arai iti rawa ki te whakaurunga mō tētahi hokohoko ahumahi nui. Anei ngā mea me manatoko e koe i runga i tētahi pepa whakatakotoranga poraka pūmau DIN rail:
IEC 60947-7-1 — Koinei te paerewa ā-ao matua mō ngā poraka taunga e whakamahia ana i roto i ngā huihuinga taputapu whakawhiti ngaohiko iti me ngā taputapu whakahaere. E tautuhi ana i te ngaohiko whakatauranga (≤1000V AC), te iahiko whakatauranga, ngā kaha whakawhiti-wāhanga, me te — he mea nui — ngā tukanga whakamātautau whakatauranga iahiko poto (SCCR)Mō ia te whakatikatika hou ki te IEC 60947-7-1, me whakapuaki mārama e ngā poraka taunga tō rātou uara SCCR, me hono tahi me ngā taputapu tiaki o runga.
UL 1059 — Ko te rite o Amerika Te Raki, e kapi ana i ngā poraka taunga tae atu ki te 1500V. He tino pakari ake te whakamātautau UL 1059 i te IEC i roto i ētahi wāhanga matua: me whakamātautau ātete hikohiko i te 2× ngaohiko whakatauranga + 1000V (me te ngaohiko whakatauranga 2× a IEC), ā, me whakamātautau huringa wera i te iahiko whakatauranga mō te 50 huringa (me te whakamātautau pikinga pāmahana pumau a IEC). Mō ia UL 1059 Putanga 6-2024, ka tāpirihia e te whakahoutanga hou ngā whakaritenga whakarei ake mō ngā poraka whakamutunga o te arai tiaki.
Ko tā mātou putea tiwhikete hei kaihanga poraka tauranga pahi tereina din kei roto: Tohu CE (te tutuki i ngā whakaritenga a te EU), rārangi UL (kei te wātea te kōnae mēnā ka tonoa), whakahaere kounga ISO 9001:2008, whakamātautau tuatoru a te SGS, tutuki i te whakaritenga a te RoHS, me te whakapuakitanga REACH. Kei roto i ia uta he tiwhikete tutuki me ngā tau puranga ka taea te whai.
He aha i whiriwhiri ai koe i tētahi Kaihanga Poraka Whakamutunga Pahi DIN Rail Haina?
Ka aro tika atu ahau ki tēnei pātai nā te mea ka pātai mai ngā tīma hokohoko i tēnei ki a mātou i ia wiki. Kua tino rerekē te ahumahi wāhanga hiko i roto i te tekau tau kua pahure ake nei. Nā te kaha hanga o Haina i whakawhāiti te rerekētanga kounga ki ngā kaihanga o Ūropi me Amerika — me te pupuri tonu i te painga utu 30-50% e ahu mai ana i te hanga poutū whakauru, ehara i te mea nā te tapahi i ngā rauemi, i te whakamātautau rānei.
Anei te tikanga o te whakaurunga poutū i roto i te mahi i roto i tō mātou whare: Ka ringihia e mātou ā mātou ake pokepokea ai werohanga i roto i te whare. Ka tāia e mātou ā mātou ake pae parahi mai i te rīpene parahi C11000 kua whakamanahia i ahu mai i Jiangxi Copper (tetahi o ngā kaihanga parahi nui rawa atu o te ao). Ka whakahaerehia e mātou ā mātou ake raina huihuinga aunoa. Ā, kei a mātou anō te taiwhanga whakamātautau o roto, he taputapu whakamātautau hiko-kore, he mita moroiti-ohm, he kāmera whakaahua wera, me te rūma whakamātautau tere-ora 500-hāora.
Mā tēnei whakaurunga poutū ka whakakorea ngā paparanga e toru o te tāpiringa utu — te kaituku rauemi mata, te kaiwhakarato wāhanga iti, me te kaiwhakaemi kirimana — e whakaurua ana ki roto i te utu o ngā poraka taunga waitohu o te Hauāuru (me kī atu ahau, kei te piki haere te hanga i Haina, engari he rerekē te tapanga).
Mō ngā OEM me ngā kaihanga panera e rapu ana mai i tā mātou wheketere tika, ko te whakamaoritanga o te ōhanga ki:
- Te whakaiti i te utu mō ia wae o te 35-50% me ngā poraka whakamutunga o te pae pahi Weidmüller, Phoenix Contact rānei, he ōrite ngā whakatakotoranga.
- Ngā wā ārahi 2-4 wiki mō ngā hua putumōhio paerewa, whakaritea ki ngā wiki 8-12 e rite ana ki ngā kaihanga o Ūropi (he rerekētanga kua whakaora i te neke atu i te kotahi o ā mātou kiritaki mai i ngā whiu whakaroa kaupapa).
- Te waitohu OEM me ngā kōwhiringa tae/whare ritenga kāore he utu taputapu tāpiri mō ngā rahinga neke atu i te 5,000 waeine — nā te mea nō mātou tō mātou toa pokepoke.
Me pēhea te whiriwhiri i te poraka whakamutunga pahi DIN Rail tika: He tukanga 5-taahiraa
I muri i te 15 tau o te whakautu i ngā pātai hangarau, kua wehewehea e au te tukanga kōwhiringa kia rima ngā whakataunga raupapa. Pekehia tētahi taahiraa, ā, ka nui rawa te whakapaunga moni ki ngā taputapu kua tohua rawatia, ka tāuta rānei i tētahi poraka taura ka noho hei mōrearea ahi.
Hipanga 1: Whakatauhia tō Auaha Tonu Mōrahi
Kaua e whakamahia te whakatauranga o te whati ara iahiko hei pūtake mōu i nāianei. Inehia, tātaihia rānei te iahiko kawenga tonu i raro i ngā āhuatanga kino rawa atu. Whakamahia te Te ture whakahekenga tonu a NEC 80%Ki te 160A te kaha e tōia tonutia ana e tō kawenga, me whai poraka tauranga koe kia 200A te iti rawa. Nā te mea kāore he whakamatao hohe o ngā poraka pito, ko te huarahi anake hei whakamarara i te wera I²R ko te horahanga mata me te kawe hiko — ā, ko te whakaiti i te rahi o te poraka ka puta he paheketanga wera tuturu o te whare polyamide.
Hipanga 2: Manatokohia te Akomanga Ngaohiko
Mō ngā pūnaha toru-wāhanga 480V (he mea noa i Amerika Te Raki), he rawaka te poraka 600V. Mō ngā pūnaha 690V (he mea noa i ngā tono ahumahi o Ūropi) me ngā whakaurunga pūngao rā 1000V, me whiwhi koe i te whakatauranga 1000V katoa. Me manatoko tonu te ngaohiko ātete hiko (Uimp) me te ngaohiko whakamarumaru kua whakatauria (Ui) — ko te ātete hiko te mea e tiaki ana i ngā whakawhiti me ngā ngaru whakawhiti e puta mai ana i te uira.
Hipanga 3: Tatauhia ō Porowhita Peka
Tatauhia ia ara iahiko e puta atu ana me whakamahi ki te pūmanawa matua o te pae pahi. Tāpirihia he 20% o te kaha tāpiri mō te whakawhānui ā muri ake nei — nā te mea ko te tāpiri i ngā tūranga i muri mai me momotu me te hono anō i te waea o te poraka katoa, he nui rawa atu te utu i te tāuta i tētahi poraka nui ake i te tīmatanga.
Hipanga 4: Whakatauritehia ngā Rahi Waea
Manatokohia kei te hipokina e te awhe whakaaetia waea o te poraka pūrua tō ara iahiko whāngai matua ME tō ara iahiko peka iti rawa. Ko te hapa kōwhiringa e kitea ana e au ko te tohu i tētahi poraka 200A me te tumanako ka tau he waea peka 1.5mm² — kāore e taea e te nuinga o ngā poraka au-rahi te piri pono ki ngā ara iahiko i raro i te 4mm². I tēnei wā, whakamahia he pine whakaiti, he wīra rānei, engari me whai whakaaro anō ki te wā huihuinga tāpiri.
Hipanga 5: Manatokohia te Whakaritenga SCCR
Tonoa te tiwhikete whakamātautau SCCR mai i tō kaihanga. Me teitei ake te uara SCCR i te iahiko hapa e wātea ana i te wāhi tāutanga. Mō ngā tono tohatoha hiko matua, ko te SCCR o te 25kA neke atu rānei i te ngaohiko kua whakatauria te iti rawa mahi — ki te iti iho i tēnā, ka noho tō poraka pūmau hei whakapūmau i roto i tō pūnaha, engari ehara i te mea i roto i te huarahi whakahaeretia.
Ngā Tikanga Pai o te Tāutanga: Ngā Mea Kāore e Kōrerotia ana e te Pepa Raraunga ki a Koe
Ka whakamōhiotia koe e ngā pepa raraunga i ngā uara taipana me te roa o ngā rīpene waea. Kāore rātou e kōrero ki a koe he aha te hē o te mahi i te mara. Anei ngā mea kua akohia e mātou mai i ngā mano tini o ngā taunekeneke tautoko kiritaki:
He mea nui ake te taipana i tō whakaaro — ā, he 10 ngā wā ka nui ake te kitea o te taipana iti i te taipana nui rawa. Ko te pūrua tīwiri kua whakaukia ki te 50% o te taipana kua whakatauria ka whakaatu i te ātete pa 3-5x teitei ake i te whakatakotoranga — ā, i te 200A, ka whakaputahia e taua ātete tāpiri he wera hei whakangawari i te whare PA66 i roto i ngā haora o te mahi tonu. Ka tukuna atu e mātou he tīwiri taipana kua whakatikatikaina mō ia tauira tuku tuatahi nā te mea e mōhio ana mātou he maha ngā toa panera e whakamahi ana i ngā tīwiri ā-ringa kāore anō kia whakatikatikaina.
Kāore e tika ana te whakamahi i te taura i runga ake i te 16mm². Ka horapa haere ngā ara iahiko parahi kua werohia, kāore he taura i raro i te pēhanga — ka pā ētahi aho, ko ētahi kāore. Ka whakaitihia te horahanga pā whai hua mā te 20-30% ki te whakataurite ki tētahi taura kua kōpiko tika, ā, ko te tikanga o tēnei he nui ake te ātete, he nui ake te pāmahana, ā, i te wā kino rawa atu — ka whati te aho i te huringa wera. Kei roto i ngā poraka taunga katoa he 25mm² te rahi, ā, kei roto i ēnei he taura parahi e tutuki ana i ngā whakaritenga DIN 46228.
Me whakapūhaumāota ngā poraka tauranga pahi. He rerekē ki ngā poraka pito whāngai e kawe ana i te iahiko mā te ara kotahi o te ara iahiko, ka kukū ngā poraka pae pahi i te 200A mā te ara kotahi o te ara parahi e rere ana i te roa o te poraka katoa. I roto i tētahi panera kapi tonu, me tāuta ēnei poraka me te āputa hau 10mm te iti rawa i ngā taha katoa — nā te mea ko te wera e whakaputaina ana e te 200A i roto i te pae pahi 16mm² he tata ki te 0.75W mō ia tūranga pūrua, ā, ka whakaputa tonu te poraka 20-tūranga i te 15W.
Ngā Pātai Auau
P: Ka taea e au te whakamahi i te poraka whakamutunga pahi 200A kotahi mō ngā tono AC me DC?
Ae, engari me ētahi whakatūpato nui. Me whakaheke te whakatauranga o te au mō te DC nā te mea kāore ngā pewa DC e tineia i a rātou anō i ngā pūwāhi whakawhiti-kore. E ai ki te IEC 60947-7-1, me whakaheke te whakatauranga o ngā poraka pito e whakamahia ana i roto i ngā ara iahiko DC ki te 80% o tō rātou whakatauranga au AC — nō reira ka noho te poraka AC 200A hei poraka DC 160A. Hei tāpiri, me ōrite te pōraretanga DC puta noa i ngā pito katoa e whakamahi tahi ana i te pae pahi; mā te whakaranu i ngā pōraretanga i runga i te pae pahi kotahi ka puta he poto poto.
P: He aha te rerekētanga i waenga i te poraka taunga pahi me te poraka tohatoha hiko?
Ka whakauruhia te pae pahi ki roto i te whare o te pae pahi, ā, ka mau ki runga i te rēra DIN. Ko te poraka tohatoha hiko (PDB) he taputapu nui ake, motuhake me tētahi pouaka motuhake, ka mau pea ki runga i te rēra DIN, kāore rānei. He nui ake te mātotoru me te māmā ake o te waea o ngā poraka tauranga pahi mō ngā tono tae atu ki te 200A; he pai ake ngā PDB i te 200A, ina kore e whai hua te huarahi whakauru nā te piko o ngā rākau waea me te marara o te wera.
Q: Kia pēhea te roa o te mau o ngā poraka whakamutunga o te pae pahi tereina DIN?
I raro i ngā āhuatanga kua whakatauria (40°C te taiao, ≤80% te kawenga tonu), ko te roanga hoahoa o tētahi poraka pahi parahi kua tāuta tika me te whare PA66 he 20+ tau. Ko te mea e whakawhāiti ana i te ora o te mea he huringa wera tonu — ko te whānui me te whakaheke o te pae parahi (CTE: 17×10⁻⁶/K) ki te whare PA66 (CTE: 80×10⁻⁶/K) ka wetekina haeretia ngā hononga tīwiri puta noa i ngā mano huringa. Mā te whakahou i te taipana ā-tau i te wā o te tiaki kua whakaritea ka roa ake te ora o te ratonga.
P: Ka taea e au te tiki whirihoranga pae pahi ritenga?
Āe. Hei kaihanga pokepoke ā-roto, he mea hanga noa e mātou ngā poraka mutunga pae pahi ritenga me te maha o ngā pou kāore i te paerewa, ngā whakatauranga iahiko whakauru i runga i te pae pahi kotahi, ngā whare tae motuhake mō te waehere ngaohiko, me te tohu/tapanga ritenga. Ka tīmata te iti rawa o ngā ota mō ngā whirihoranga ritenga i te 1,000 waeine, me te utu mō ngā taputapu kei roto i te utu waeine.

Q: He hototahi ngā poraka terminal J-Guang ki ngā taputapu mai i ētahi atu waitohu?
Ka whakamahia e ā mātou poraka tauranga tereina DIN te kōtaha tereina TS-35 paerewa-a-umanga me te mokowā waenga paerewa (ko te tikanga he 6mm, 8mm, 10mm rānei i runga i te raupapa). Ko ngā whīra pito, ngā pereti wehewehe, me ngā rīpene tohu he mea hototahi ki ngā waitohu nui (Weidmüller W-Series, Phoenix Contact UK-Series) nā te mea he paerewa ahumahi ēnei ine — ahakoa e taunaki tonu ana mātou kia manatokohia te hototahitanga ā-mīhini me te tauira i mua i te tuku i ngā ota nui.
