Kaiwhakarato Poraka Whakamutunga Pana-roto: Tāutanga Kore-Utauta me te Pupuri Taipana mō ngā Paewhiri Mana

Mena kei te rapu koe i tētahi kaiwhakarato poraka pito pana-roto e whakakotahi ana i te tāutanga kore-taputapu pono me te pupuri taipana kua whakamātauhia, koinei te mea tino nui: I Ningbo J-Guang Electronics Co., Ltd., kua 15 tau mātou e hanga ana i ngā poraka whakamutunga pana-roto DIN-rail e whakakorea rawatia ana te tīwiri, me te whakarato hoki i te kaha piri pumau, kore tiaki. Ka whakamahia e tā mātou poraka pito PCT-211 he pūnaha puna kowiri tira kua tāia hei whakaputa i te 32 N ki te 48 N o te kaha pa ki ia whakaurunga waea. — ahakoa kei te whakamutu tuatahi te tohunga hangarau i te ata, kei te whakamutu rānei i te 500. Nā te mea kāore he tīwiri hei whakau, kāore he taipana hei manatoko, kāore he nekehanga whakatikatika mai i ngā taputapu kua tawhito, ā, kāore he mahi anō i puta mai i ngā hononga kāore i te tino taipana e rahua ana i te wā e whakatūtūria ana te panera. Ka whakaea aunoatia e te puna kua whakatōngia i mua te whānui me te wiri., he mea kāore e taea e te hononga tīwiri taipana-pūmau te mahi. I roto i ā mātou whakamātautau kaha whakauru wheketere puta noa i te 1,000 huringa karapīpiti, i pupuri te PCT-211 i te ātete whakapā i raro i te 3.2 mΩ me te kore he hekenga ine i roto i te kaha puna - he hua ka manatokohia e mātou i runga i ia puranga whakaputa. Ko tēnei huinga o te tāutanga kore-taputapu me te pupuri taipana tonu te take e whiriwhiri tonu ai ngā kaihanga papa whakahaere i roto i ngā rāngai rerewē, motuka, me te aunoatanga ahumahi i a J-GUANG hei kaiwhakarato poraka taunga pana mō ngā tono waea kiato teitei.

He aha i whiriwhiri ai i te poraka whakamutunga pana-roto, kaua i te hononga momo-tīwiri mō ngā papa whakahaere?

Ko te rerekētanga matua ko te pana i te poraka pito ka whakakapi i te tono taipana e whakawhirinaki ana ki te tangata ki te pūnaha puna kua whakaritea e te wheketere., te tango i te taurangi kotahi nui rawa atu i roto i te kounga o te whakamutu. I roto i ngā poraka momo tīwiri, ko te pono o te hononga e whakawhirinaki ana ki te taipana e whakamahia ana e te tohunga hangarau - ko te tikanga 0.5 Nm ki te 0.8 Nm mō te ara iahiko 2.5 mm² - ā, e whakaatu tonu ana ngā rangahau i roto i ngā waea ahumahi tae atu ki te 15% o ngā whakamutu tīwiri i roto i ngā panera kua huihuia ki te mara ka taka ki waho o te matapihi taipana kua tohua.

He rerekē ia, ka wehea e te hangarau pana-whakauru te kounga o te tāutanga mai i te pūkenga o te kaiwhakahaere. Ka whakatōtōhia te puna i mua i te wā e hangaia ana kia rite ki te kaha kua tatauhia e tutuki ana i ngā whakaritenga IEC 60947-7-1 puta noa i te whānuitanga whakawhiti waea katoa (0.14 mm² ki te 6 mm² mō tā mātou PCT-211). Ka whakauru noa te tohunga hangarau i te ara iahiko kua whakaritea kia tau rawa, ā, ka whakamahia e te puna tōna kaha piri kua hoahoatia - i ia wā, i ia wā, he rite tonu. Ko tēnei ōritetanga te take tino kaha ki te tiki mai i tētahi kaiwhakarato poraka taunga pana-roto e hanga ana i āna ake tikanga puna i roto i te whare., pērā i a J-GUANG, nā te mea ko te mahi a te puna ka whakatauhia e te hanganga rauemi, te maimoatanga wera, me te tika o ngā āhuatanga — ehara i te taraiwa taipana i runga i te papa mahi a te kaihanga panera.

Kua kite ahau i ngā raina huihuinga papa whakahaere i te wā i whakawhiti ai ahau mai i te momo tīwiri ki ngā poraka whakamutunga pana-roto i whakaiti i te reiti rahunga tuatahi mai i te 8.3% ki raro iho i te 0.5%, me te wā huringa huihuinga papa mā te 52%. Ehara ēnei i te whakapainga arorau — i ahu mai ēnei i ngā raraunga whakaputa tuturu puta noa i ngā whare kiritaki e toru i huri i waenga i te tau 2023 me te 2025.

He pēhea te pupuri pono o te taipana i te poraka whakamutunga pana-roto?

Ehara te pupuri taipana i roto i te poraka pito pana-whakauru i te āhuatanga e tirohia ana i te wā tāutanga — engari he āhuatanga rauemi kua hangaia ki roto i te maitai puna. He rerekē tēnei i te hononga tīwiri e heke ana te kaha o te kume i te wā e whakangā ana te tīwiri i raro i te huringa wera (he āhuatanga e mōhiotia ana ko te "whakangā whakaurunga"), ka mau tonu te kaha o te tikanga kume puna mā te whakarerekētanga pīngore o te huānga puna kowiri tira.

Anei te mātāpono hangarau: Ina whakakīia te pito o te tīwiri, ka totoro te pūtu kia ngawari hei hanga i te kaha kume. Engari ki te pēhia, ki te ngokingoki rānei te waea i raro i te pane o te tīwiri — he mea e tino pāngia ana e ngā ara iahiko parahi, inā koa i ngā pāmahana teitei — ka heke te kukū o te pūtu nā te mea kua mau te roa o te ngawari. He rerekē te puna pana-ki-roto, ā, ka roa ake te awhe haere pīngore o te puna, ko te nuinga he 1.5 mm ki te 2.5 mm te piko o te puna. Ina tau, ina pēhia rānei te ara iahiko, ka peka ke noa atu te puna ki roto i tōna rohe pīngore, ka mau tonu te kaha pumau. Koinei te take e paahitia ai e ngā poraka pito pana-whakauru te whakamātautau pikinga pāmahana IEC 60947-7-1 me ngā rahi waea mai i te 0.5 mm² ki te 4 mm² Ahakoa ka hē ētahi poraka tīwiri i te whakamātautau kotahi ina kore te tīwiri e whakaukia anō i muri i te huringa pāmahana tuatahi — he taahiraa tēnei e karohia ana e te nuinga o ngā kaihanga panera i roto i te mahi.

I J-GUANG, ka whakamanahia e mātou te pupuri taipana mā te whakamātautau huringa wera tere: 200 huringa mai i te −40°C ki te +105°C, me te ine i te ātete pa i muri i ia 25 huringa. Ka mau tonu tā mātou raupapa PCT-211 i te ātete pa i raro i te 3.2 mΩ puta noa i te whakamātautau, me te kore he huringa ine i roto i te rahi o te āputa puna. I whakaputaina e mātou tēnei huinga raraunga hei wāhanga o ā mātou tuhinga kounga, ā, ka taea e tetahi kiritaki te tono i te pūrongo whakamātautau me tā rātou ota tauira.

Ngā Mea hei Tirotiro māu ina Aromatawai ana i tētahi Kaiwhakarato Poraka Whakamutunga Pana-roto

Ehara i te mea ko ngā kaiwhakarato katoa e tuku ana i ngā poraka whakamutunga pana-roto e hanga ana i ēnei ki te paerewa kotahi, ā, he mea nui ngā rerekētanga — ina koa me paahitia e ō papa whakahaere te tirotiro UL 508A, me te tutuki rānei i te IEC 60204-1. I runga i aku wheako ki te aromatawai i ngā kaiwhakarato puta noa i Haina, i Ūropi, me te Tonga-mā-rāwhiti o Āhia, koinei ngā paearu e rima e taunaki ana ahau kia arohia e ngā tīma hoko:

Tuatahi, manatokohia kei te hangaia e te kaiwhakarato ā rātou ake hononga puna i roto i te whare, kaua ki te hoko i ngā whakauru whānui. I whakangao mātou ki tā mātou ake raina tā mo ngā puna PCT-211 nā te mea ko te kaha o te hononga e tautuhia ana e te āhua o te puna, te matotoru o te rauemi, me te maimoatanga wera — ko ngā ātete e kore e puritia e ngā kaiwhakarato o waho ki te ±0.03 mm. Ka taea e te rerekētanga 0.05 mm i roto i te āputa puna te whakarerekē i te kaha whakauru tae atu ki te 15%, e pā tika ana ki te wheako kaiwhakamahi (ka hoha te tohunga hangarau ki te kaha nui) me te pono o te hononga.

Tuarua, whakaūtia kua whakamatautauria te tikanga pana-ki-roto ki te IEC 60947-7-1 me te UL 1059, kaua ki te "hangaia kia tutuki noa." Ka tukuna atu e mātou ngā puranga whakaputa katoa — ehara i te mea ko ngā tauira anake — ki IEC 60947-7-1 whakamātautau tuatoru mō te pikinga pāmahana, te kaha hiko-kore, me te manawanui ā-pūkaha. Kei te wātea te pūrongo whakamātautau mō ngā tono katoa a te kiritaki.

Tuatoru, aromatawaihia te whānuitanga waea a te kaiwhakarato. Me kapi te whānuitanga o te poraka taunga mai i te 0.14 mm² (AWG 26) ki te 6 mm² (AWG 10) puta noa i tā rātou raina hua DIN-rail. Ka kapihia e tā mātou raupapa PCT-211 tēnei whānuitanga i roto i te whānui o te whare kotahi o te 5.2 mm, me ngā momo tae kua tohua mō te hina (whāngai-roto), te kikorangi (tohatoha kūpapa), me te kakariki-kōwhai (whenua).

Tuawhā, pātai atu mō ngā kōwhiringa mō te takai me te tohu. Kei a mātou te tohu taiaho ritenga, te takai rīpene-me-rīra mō te huihuinga aunoa, me te waitohu tapanga tūmataiti — ngā āheinga he mea nui ina whakauruhia e koe ngā poraka ki roto i tētahi hua papa whakahaere paerewa.

Tuarima, tonoa he pūrongo whakamātautau wiri. Me taea e te kaiwhakarato poraka taunga pana-i roto te whakarato i ngā raraunga whakamātautau tuatoru mō ia IEC 60068-2-6 he rite rānei. I roto i ā mātou ake whakamātautau, ka pupuri te rawhi puna PCT-211 i te haere tonu o te hiko i raro i te wiri sinusoidal 5 karamu mai i te 10 Hz ki te 150 Hz, me te kore he haruru pa, he whakatuwheratanga wā poto rānei. Koinei te whakaritenga kotahi i whakaritea mō ngā taputapu tohu rerewē — he paearu e wehewehe ana i ngā poraka pito taumata-wāhanga mai i ngā poraka taumata-ahumahi.

Ko te tino take: ina arotakehia e au ngā kaiwhakarato mō ā mātou ake kiritaki kaihanga panera, ka kī tonu ahau he pai te puna o te kaiwhakarato poraka taunga ina panaia mai — ka taea te tiki i ngā mea katoa (te whare, te tohu, te takai), engari ko te puna te ngako o te hua. Ki te kore te kaiwhakarato e whakahaere i tā rātou hanga puna, kāore he taurangi ka mahi anō te mahi pupuri i mahi i roto i te tauira puta noa i te ota whakaputa.

Kia pehea te roa o te wā huihuinga ka taea te penapena mā te pana i ngā poraka taunga i roto i te Paewhiri Mana?

Ehara i te mea he pikinga te penapena wā mai i te waea pana-roto kore-taputapu — he huringa nui tēnei i roto i te tukanga huihuinga, ā, e tautokona ana tēnei e ngā tatauranga puta noa i ngā paearu maha motuhake. Ngā poraka pūrua pana-roto a Phoenix Contact kua tuhia hei whakangawari i ngā pūnaha waea, ā, e ai ki ngā whakataurite motuhake ka taea e ngā pūnga pana-whakauru te whakaiti i te wā waea tae atu ki te 40% ki te whakaritea ki ngā pūnga utaina-puna. Ngā Aositerminals e whakamana ana anō i te mea i roto i ngā panera rama kāinga atamai, i whakaitihia e ngā pūnga pana-whakauru te wā waea mā te tata ki te 40%.

Tukua ahau kia hoatu he tauira tūturu mai i tētahi kiritaki e mahi tahi ana mātou. He kaihanga papa whakahaere Pākehā e huihui ana i te 600 papa ia marama, ia papa he 180 ngā pito DIN-rail, i whakawhiti mai i te momo tīwiri ki ā mātou poraka pana-roto PCT-211 i te tīmatanga o te tau 2024. I mua i te whakawhiti, e 2.8 hāora te roa o te wā e pau ana i tā rātou tīma waea, he 12 ngā tohunga hangarau, mō ia panera ki te waea i te taunga me te manatoko i te taipana. I muri i te whakawhiti, e 1.2 hāora te roa o te wā e pau ana i taua panera anō — he hekenga 57%. I ahu mai ngā penapena wā i ngā panonitanga motuhake e toru: kāore he whakamahi tīwiri mō ia pito (12 hēkona te penapena mō ia waea i te toharite), kāore he taahiraa manatoko taipana (8 hēkona te penapena mō ia waea), me te kore mahi anō mai i ngā hononga koretake i kitea i te wā tirotiro QC (18 meneti te penapena mō ia panera i te toharite).

I roto i ngā panera 600 ia marama me te hekenga 57%, i whakahokia mai e taua kiritaki tata ki te 960 hāora mahi ia marama. — he rite ki te tāpiri i ētahi atu tohunga waea wā-katoa e ono, me te kore e utu i tētahi. Mō tētahi kaihanga panera e whakahaere ana i ngā tawhē iti, ehara ēnei tau i te inenga whai huatanga anake; engari he pānga tika ki te hua me te kaha tuku.

Me tāpiri atu e au tētahi whakatūpato ki konei: ko ēnei penapena e kī ana ka whakamahia e te hoahoa o te panera he arataki totoka, he waea aho rānei kua herea ki te taura. Mena ka mahi tō whare i ngā waea aho-iti kāore he taura, me tāpiri he taahiraa whakapiko taura, hei whakaiti i te pikinga o te wā. I ngā taiao waea whakauru, ka kitea e mātou he penapena wā kupenga e 40% ki te 50%, kaua ki te 60%+ e taea ana me te waea katoa-ferruled. — he nui tonu, engari he mea tika kia whakaarohia i roto i tō tātaritanga rerenga mahi.

Ka Mahi te Hangarau Pana-Whakauru mō ngā Porowhita Paewhiri Mana Au-Tiketike?

Āe, engari mēnā anake ka tika te hoahoa a te kaiwhakarato poraka taunga pana-roto i te ara kawe-iao — ā, ehara te wero hangarau i te puna engari ko te pae iao me te whakahaere wera. Ko tā mātou raupapa PCT-211 he 24 A i te 800 V me te ara iahiko 2.5 mm² (32 A me te 4 mm²), e kapi ana i te nuinga o ngā ara iahiko tohu me te hiko o te papa whakahaere. Mō ngā tono au-rahi ake, ka mahi tahi mātou me ngā kiritaki ki te whiriwhiri i ngā poraka e tika ana me ngā kauhanga ara iahiko nui ake me ngā pae au-whānui ake., tae atu ki te 125 A mā te whakamahi i ngā ara iahiko 35 mm².

Ko te tawhā hoahoa matua mō ngā poraka pana-whakauru he nui te au ko te ātete hononga i waenga i te hononga puna me te pae au. I roto i te poraka tīwiri, ka pēhia tika te ara iahiko e te pane tīwiri ki te pae, ka hangaia he hononga whakarewa-ki-te-whakarewa me te ātete iti - ko te tikanga 0.1 mΩ ki te 0.3 mΩ. I roto i te poraka pana-whakauru, me tutuki te pēhanga puna i te ātete hononga ōrite mā te whakamahi i te kaha puna anake, me te kore he painga ā-pūkaha o te tīwiri miro. Koia te take e whakamahia ai e tā mātou PCT-211 he pae au koranu parahi whakakikoruatia ki te tine me te puna kowiri tira e whakaputa ana i te iti rawa o te 32 N o te kaha whakapā mō ia ara iahiko. — he rawaka hei whakatutuki i te ātete atanga i raro i te 0.15 mΩ i te wā e hangaia ana, kei roto tonu i te whakaritenga IEC 60947-7-1 o te ≤ 3.2 mΩ ātete ara iahiko katoa.

Ka whakamanahia tēnei e mātou i runga i ia puranga whakaputa mā te whakamahi i tētahi mita moroiti-ohm e 4-waea, ā, ko tā mātou taupū āheinga tukatuka (Cpk) mō te ātete whakapā kei runga ake i te 1.33 — ko te tikanga 99.99% o ngā wae whakaputa e tutuki ana i te whakaritenga. Mena e hiahia ana koe ki ngā poraka pūrua mō ngā ara iahiko neke atu i te 32 A, ka tūtohu ahau kia kōrerohia tō au me tō huringa mahi motuhake ki tā mātou tīma hangarau., nā te mea he rerekē te mahi wera i runga i te hauhautanga o te whare herehere me te paihere ara iahiko, ā, e rua ēnei ka pā ki te pihi whakaheke hiko.

Te Mārama ki te Whenua Tiwhikete mō ngā Poraka Whakamutunga Pana-roto

Ina hiahia tō papatohu whakahaere kia paahitia te tirotiro UL 508A, kia tutuki rānei i ngā whakaritenga tohu CE, ka uru te tiwhikete o ia poraka taunga ki roto i te mekameka tutuki a te papatohu. Koinei te mea e whakanuia ana e au ki ia kiritaki hou: ko te poraka taunga iti rawa te utu i te mākete, koia te mea tino utu nui mēnā ka rahua tō panera i te tirotiro whakamutunga.

Ko ngā paerewa matua e whakahaere ana i ngā poraka whakamutunga pana-mai mō ngā papa whakahaere ko:

IEC 60947-7-1 — Koinei te paearu ā-ao mō ngā poraka pito i roto i ngā tono ahumahi. E tohu ana i te ātete hiko-kore (iti rawa 2.5 kV), te pikinga pāmahana (≤ 45 K i runga ake i te taiao i te iahiko whakatauranga), te manawanui miihini (≥ 50 huringa whakaurunga me te kore he), me te ātete mura (whakamātautau mura ngira). Me whakarato he pūrongo whakamātautau mai i tētahi taiwhanga whai mana mō tētahi kaiwhakarato poraka pito e kī ana he tutuki ngā whakaritenga.

UL 1059 — Mō ngā whakaurunga panera o Amerika Te Raki, ko te UL 1059 te paerewa e tika ana. Ko te rerekētanga matua mai i te IEC 60947-7-1 ko te hiahia o te UL 1059 ki ngā ngaohiko whakamātautau hiko teitei ake me te whakarōpūtanga mōrearea ahi tāpiri. Kua hangaia ā mātou poraka PCT-211 kia tutuki i ngā paerewa e rua i te wā kotahi, me te whare PA66 kua whakatauria he V0 mō ia UL 94 whakamātautau mura me te taupū aroturuki whakatairite (CTI) o te 600 V.

Te tutuki i te RoHS me te REACH — He mea whakahau ēnei mō te urunga atu ki te mākete o te EU. Ka whakamahia e ngā poraka pito J-GUANG he koranu parahi whakakikoruatia ki te tine me te PA66, kāore he matū e herea ana, me ngā tuhinga hanganga ture e whakaratohia ana mō ia ota.

Kua kite ahau i ngā tīma hokohoko e moumou wiki ana ki te aromatawai i ngā kaiwhakarato nā te mea i kī mai ko ā rātou aukati he "ture IEC" me te kore he tuhinga whakamātautau tautoko. Ko tāku tūtohutanga: pātaihia te ingoa o te taiwhanga whakamātautau me te nama pūrongo i mua i te tono tauiraMā te kaiwhakarato poraka taunga pana-i roto e whai tohu ēnei e whakarite — kei a mātou he whare pukapuka o ngā pūrongo whakamātautau e wātea ana mā te puka tono ngāwari.

Te Whakataurite o J-GUANG ki Ētahi Atu Kaiwhakarato Poraka Whakamutunga Pana-roto

Ka māmā noa iho taku kōrero: mō te rahinga whakaputa mata, he iti ake a J-GUANG i a Phoenix Contact, i a Weidmüller rānei. Engari mō ngā kaupapa OEM me ODM rahinga-waenga — 5,000 ki te 500,000 ngā wahi mō ia ota — ka tukuna e mātou he painga kāore e taea e ngā kaiwhakarato nui te rite.

He arotahi ā mātou hua, arā, he kounga teitei ake mō ia wāhanga. Ahakoa e tuku ana tētahi kaiwhakarato nui i te 50,000 SKU puta noa i ngā whānau hua 15, ko tā mātou poraka pito PCT-211 me te PCB screw terminal block 301-5.0 te nuinga o tā mātou rahinga whakaputa. Mā tēnei arotahi ka taea e mātou te pupuri i te mana whakahaere tukanga pakari ake — ka whakatauritea ā mātou uara Cpk ki ngā inenga pai rawa atu o te umanga poraka pito, ehara i te mea ko te "paahi" noa i te whakatakotoranga iti rawa.

Ka tukuna e mātou he utu tika ki te wheketere, kāore he utu tāpiri mai i ngā kaituku rohe. Ina mahi tahi koe me J-GUANG hei kaiwhakarato poraka taunga pana-roto, kei te hoko koe i te utu kotahi me te kaihoko Tiamana e hoko mai ana i tetahi OEM Hainamana, ā, ka piki ake te utu mā te 25% ki te 40% mō te mākete Tiamana. Ko tā mātou MOQ paerewa he 500 ngā wahi mō ia tau wāhanga, me ngā rahinga tauira e wātea ana hei aromatawai i roto i ngā rā mahi e 7 ki te 10, mai i te tatau ki te tatau mā te kaikawe tere.

Ka whakaratohia e mātou he whakaritenga OEM e kore e whakaaetia e ngā kaiwhakarato nui. Me hiahia koe ki te tohu tae ritenga, ki tētahi whakatakotoranga takai motuhake mō tō raina whiriwhiri-me-te-tū, ki tētahi tapanga motuhake rānei i te taha o te whare? He tono noa ēnei mā mātou. Ā mātou raina hua katoa kei roto ko ngā poraka pana-roto DIN-rail, ngā poraka pito tīwiri PCB, me ngā otinga hononga tāpiri ka taea te whakarite kia rite ki te tahora o tō panera.

Ngā Whakaaro Whaihua mō te Huri ki ngā Poraka Whakamutunga Pana-roto

Mena kei te aromatawai koe i tētahi panoni mai i te momo tīwiri ki ngā poraka whakamutunga pana-roto puta noa i ngā hoahoa o tō papatohu whakahaere, e toru ngā whakaaro whakahaere hei whakatau i te maeneene o te whakawhiti.

Tuatahi, whakahoutia ō paerewa whakarite waea. He pai ake te mahi a ngā poraka pana-roto me ngā waea totoka, ngā waea kua herea ki te taura. Mena ka whakaaetia e ō paerewa waea o nāianei ngā waea kua herea ki te taura (he mea noa mō ngā pito tīwiri), me tāpiri e koe te whakakoi taura ki tō BOM, me te whakangungu i ngā tohunga hangarau ki te whiriwhiri i te taura — me ōrite te taura ki te ine waea me te diameter o te kauhanga o te poraka pito. Ka whakaratohia e mātou he aratohu whiriwhiri taura me ia tauira hei whakahaere i tēnei whakawhiti.

Tuarua, whakaarohia te ara ako. E ai ki ō mātou wheako, ko ngā tohunga hangarau kua neke atu i te 10 tau e whakamahi ana i ngā pito tīwiri ka ātete i te tīmatanga ki ngā poraka pana-whakauru nā te mea "kāore e rite ki te hononga pakari" me te kore he urupare pā o te whakakī i te tīwiri. Ko te tikanga ka memeha tēnei ātete i roto i ngā wiki e rua ki te toru o te whakamahinga, engari he mea nui i te wā e whakarewahia ana. Ka tūtohu mātou kia rua hāora te wā whakangungu ā-ringa me ngā poraka tauira i mua i te whakawhiti raina whakaputa — Ka whakaratohia e mātou tēnei whakangungu mō te kore utu ki ngā kiritaki hou.

Tuatoru, manatokohia te hototahitanga o te tahora o te papaaho. He rite tonu te tapuwae o ngā poraka pana-roto ki ngā poraka momo-tīwiri ōrite i roto i te whakatauranga iahiko ōrite — ka whakairihia ēnei ki runga i ngā rēra paerewa NS 35/7.5, NS 35/15 rānei — nō reira ka mau tonu te tahora o ō panera me ngā rahi o te pouaka. Ko te rerekētanga ā-ahu anake ko te roa o te poraka: he poto ake ngā poraka pana-roto i ngā poraka tīwiri ōrite i te nuinga o te wā, he 2 mm ki te 4 mm te poto ake nā te mea kāore he pourewa tīwiri, e whakapai ake ana i te rere o te hau me te wāhi piko waea i roto i te pouaka.

Mai i te tirohanga o te mekameka tuku taonga, he māmā noa te whakawhiti. Ka whakakapia e koe tētahi tau wāhanga ki tētahi atu, ka whakahoutia ō tohutohu mahi huihuinga, ā, ka noho rite tonu te toenga o te panera — te tohatoha hiko, ngā PLC, ngā whakawhiti, ngā whakapā. Ko te huarahi tere ki te whakamana i tēnei ko te tono tauira o ā mātou PCT-211 pana i roto i te poraka tauranga mō te hanganga o tētahi papaaho whakamātautau. Kei roto i tā mātou tauira tuku noa he 50 ngā wahi mō ia tau wāhanga e tonoa ana, me te pepa raraunga hangarau me te pūrongo whakamātautau IEC 60947-7-1.

Ngā Whakaaro Hē Noa mō ngā Poraka Whakamutunga Pana-roto — Kua Whakatikahia

Whai muri i ngā tau maha o ngā kōrerorero ki ngā kaihanga panera me ngā miihini hoko, ka rangona tonutia e au ngā āwangawanga ōrite. Anei ngā whakaaro hē e tino kitea ana mō te hangarau pana-mai me te ao hangarau kei muri i ia mea.

Whakaaro Hē 1: "He iti ake te haumaru o ngā hononga pana-whakauru i ngā hononga tīwiri." Kei te mau tonu tēnei whakaaro hē nā te mea ko te urupare pā o te whakakīkī o te tīwiri ka hanga he āhua hinengaro o te "haumarutanga" kāore e taea e te poraka pana-whakauru, me tana whakaurunga pāwhiri-kotahi. Ko te mea pono, ko te kaha pupuri puna i roto i te poraka pana-whakauru i hangaia tika - 32 N ki te 48 N i runga i tā mātou PCT-211 - ka nui ake i te kaha piri o te tīwiri M3 kua whakakīkīhia i roto i te maha o ngā hoahoa pito tīwiri. Kua whakamatautauria e mātou ngā mano tini o ngā ara iahiko kua mutu: ka pakaru te hipoki waea i mua i te tukunga o te puna.

Whakaaro Hē 2: "Kāore e taea e ngā poraka pana-roto te whakahaere i te huringa wera." Ko te ritenga kē te pono. Nā te mea ka āwhina te pūnaha puna ki te whakaea te whānui o te wera, ka pai ake ngā poraka pana-roto i ngā pito tīwiri i roto i ngā whakamātautau huringa wera. Kāore ā mātou whakamātautau koroheketanga tere i te 200 huringa mai i te −40°C ki te +105°C e whakaatu ana i te huringa ine o te ātete pa — he hua ka tutuki noa i ngā pito tīwiri mēnā ka whakakīia anō te tīwiri i muri i te huringa whakamahana tuatahi.

Whakaaro Hē 3: "Ko ngā poraka pana-roto he mea mō ngā iahiko taumata-tohu anake." Ko ā mātou poraka PCT-211 he mea whakatau mō te 24 A tonu i te 800 V me ngā ara iahiko 2.5 mm², e kapi ana i ngā whāngai mana mō ngā whakapā, ngā tīmatanga motuka, me ngā whakawhiti mana whakahaere i te nuinga o ngā panera ahumahi. Mō ngā ara iahiko teitei ake tae atu ki te 125 A, ka tūtohu mātou i ā mātou poraka pana-whakauru nui ake me te kaha o te ara iahiko 35 mm². — e whakamahia whānuitia ana ēnei i roto i te tohatoha hiko me ngā ara iahiko whāngai matua.

Whakaaro Hē 4: "He nui ake te utu o ngā poraka pana-roto i ngā momo tīwiri." I te taumata wāhanga, ko te utu mō te poraka pana-whakauru he 15% ki te 25% te nui ake i te poraka momo tīwiri rite. Engari ki te whakaarohia te utu tāutanga — tae atu ki te mahi, te manatoko taipana, te mahi anō, me te para taumata-panel — ko te utu katoa o te mana pupuri he iti ake i te nuinga o te wā mō ngā poraka pana-whakauru. Ko te whakahekenga 57% o te mahi waea a tā mātou kiritaki i whakamaoritia hei whakahekenga 32% i te utu whakamutu mō ia panera, ahakoa te utu wāhanga teitei ake.

Ngā Pātai Auau

He aha te pana i roto i te poraka tauranga? Ko te poraka pito pana-roto he hononga hiko e mau ana ki te reera-DIN e whakamahi ana i te tikanga puna-piri kua whakaroahia hei whakau i ngā waea me te kore e hiahiatia he tīwiri, he taputapu taipana rānei. Ka whakauruhia tika ngā ara iahiko totoka me ngā waea kua herea me ngā taura ki roto i te wae whakapiri, ka pā te puna, ka mau tonu te kaha pa.

Me pēhea te pupuri i te taipana mā te pana i te poraka tauranga? Ka tutuki te pupuri taipana i roto i te poraka pito pana-roto mā te pūnaha puna maitai kore waikura kua tāia e pupuri ana i te kaha piri tonu ki te ara iahiko. Kāore i rite ki ngā pito tīwiri e taea ai e te wiri te wetewete haere i te tīwiri, ka whakarerekē te hoahoa puna-piri i a ia anō ki te whakawhānui me te whakaheke wera, me te pupuri i te pēhanga whakapā rite tonu puta noa i ngā huringa pāmahana mai i te −40°C ki te +105°C.

He rite te pono o ngā poraka pito pana-roto ki ngā poraka pito tīwiri? Āe. Ka tutuki, ka hipa rānei ngā poraka pito pana-roto i ngā paerewa IEC 60947-7-1 me UL 1059 rite tonu ki ngā poraka pito tīwiri mō te haumaru hiko me te manawanui miihini. I roto i ngā taiao wiri-ātete, he maha ngā wā ka pai ake ngā hononga pana-roto i ngā pito tīwiri nā te mea ka mau tonu te kaha pa o te pūnaha puna ahakoa te auau wiri.

He aha ngā tiwhikete kei roto i ngā poraka terminal e panaia ana e J-GUANG? Ko ngā poraka pana J-GUANG i roto i ngā poraka pito kua hangaia kia rite ki ngā paerewa IEC 60947-7-1, UL 1059, me RoHS. E whakamahi ana ngā poraka i te whakamarumaru ātete-mumura PA66 V0 ia UL 94, ngā ara iahiko koranu parahi whakakikoruatia ki te tine, me ngā hononga puna kowiri tira kua whakamatautauria mō te iti rawa o te 500 huringa whakaurunga.
