TL;DR

• Ka honoa te āputa i waenga i ngā ara iahiko whakahaere kiato me te tohatoha ahumahi iahiko-teitei e te poraka mutunga tīwiri PCB 5.0mm, e āhei ai ngā ara iahiko 14AWG ki te 10AWG, kāore he taputapu motuhake.
• Ko te whakatauranga 150A e whakawhirinaki ana ki te kawe hiko o te koranu parahi me te taipana tīwiri tika, ehara i te mea ko ngā āhuatanga ā-tinana anake, ā, ko ngā hapa tāutanga parae tonu te tino take o te rahunga wawe.
• He pai ake te mahi a te whakapūmau tīwiri i ngā pito puna pana-whakauru i roto i ngā tono kawenga motuka nā te mea ka ngenge te puna i te wiri, engari ka mau tonu te ātete pa o ngā hononga tīwiri i raro i te kawenga huringa 5g ina tika te whakapūmau.
• E tika ana kia rua ngā tiwhikete ki te UL 1059 me te IEC 60947-7-1 mō te tohatoha puta noa i te ao, engari ko ngā poraka pito CE-anake ka whakahēngia i roto i ngā pūnaha 480V o Amerika Te Raki ina hiahiatia ana e ngā waehere ā-rohe ngā tohu wāhanga kua whakamanahia.
• E whakaatu ana ngā whakamātautau tere ake i te roa o te ora i raro i ngā tikanga wiri me te huringa wera IEC 60068-2-6 ko te wetewete o ngā tīwiri te momo rahunga matua i roto i ngā rūma kōpeke me ngā papa whakahaere motuka o waho, ehara i te pirau o ngā rauemi.

Ina whakatuwherahia e koe he papa whakahaere motuka i roto i tētahi whare ahumahi, he rite tonu te wāhanga tohatoha hiko ki tētahi pakitara poraka matomato me te hina e mau ana ki runga i tētahi reera DIN. Ka tohua e ngā miihini ēnei poraka taunga mā te whakatauranga o te au me te tawhiti, me te kore e nui te whakaaro. He hapa tēnā. Kei roto i te kāwai tawhiti 5.0mm tētahi wāhi motuhake i roto i ngā poraka taunga tīwiri PCB e noho ana i waenganui i te mokowā kuiti 3.5mm o te waea tohu me te mokowā 7.5mm, 10mm rānei o te tohatoha ngaohiko teitei. Koinei te wāhi pai mō te tohatoha hiko nā te mea ka uru ki roto ngā ine waea e kawe ana i te au whai tikanga me te pupuri tonu i te āhua whakairi PCB e pai ana ki ngā kaihoahoa whakahaere. Ehara i te mea tūpono te kaha o te au 150A e kīia ana e ngā kaihanga pēnei i a Ningbo J-Guang Electronics. E whakaata ana i ngā kōwhiringa rauemi, te āhua tīwiri, me ngā whakaaro whakahaere wera e pakaru ana mēnā ka rerekē te taiao tāutanga mai i ngā tikanga whakamātautau. He maha ngā tau e mātakitaki ana ahau i ngā tīma hoko e whiriwhiri ana i ngā poraka taunga i runga i te utu mō ia pou, me te kore e aro ki ngā tikanga mara e whakatau ana mēnā ka ora aua pou i roto i ngā tau e rima, i ngā marama e rima rānei. Ko te āputa i waenga i ngā whakatauranga rarangi me te mahi o te ao tūturu te wāhi e puta mai ai te nuinga o ngā hapa tohatoha.

He aha te Pitch 5.0mm te Wāhi Pai mō te Tohatoha Ahumahi

I puta mai te papa 5.0mm hei whakataurite. Kāore e taea e ngā papa iti te whakahaere i te ine waea, i te kiato iahiko rānei e hiahiatia ana mō te tohatoha hiko. Ka moumou ngā papa nui i te PCB, ā, ka nui ake te tapuwae whānui o te papa whakahaere. Mō ngā kaihanga e aro ana ki te whakahaere motuka ahumahi, te aunoatanga whare, me ngā kaitahuri hiko whakahou, ko te mokowā 5.0mm e tohu ana i te taurite i waenga i ngā whakaritenga mokowā hiko me te kiato miihini. He rawaka ngā tawhiti ngoki me te tawhiti ātea i tēnei papa mō ngā pūnaha 1000V i raro i te IEC 60947-7-1 ina tika te whakatauranga o te rauemi turanga, koia te take e aro nui ai tēnei paerewa ki ngā poraka whakamutunga mō ngā taputapu ahumahi me ngā ngaohiko whakatauranga tae atu ki te 1000V.

Hototahi ki te Ine Waea: 14AWG ki te 10AWG Kāore he Whakarerekētanga Utauta

Ko tētahi painga mahi o te piko 5.0mm ko te whānuitanga waea e uru ana me te kore e akiaki i te kaiwhakauru ki te whakarerekē i ngā mate kume, i ngā roa rīpene rānei. Ka taea e te raupapa poraka pito kotahi te whakahaere i ngā kaiārahi 14AWG mō ngā tohu whakahaere me ngā kaiārahi 10AWG mō ngā whāngai hiko. He mea nui tēnei i te papa o te toa. Mena me whakamutu e te tohunga hiko tētahi panera whakauru me ngā waea tohu me te hiko, mā te whakamahi i tētahi whānau poraka pito kotahi ka whakaiti i te utu taputapu me te whakangungu. Ko te tikanga kume tīwiri i roto i te tikanga noa Poraka whakamutunga tīwiri PCB 5.0mm Ka whakamahia he hoahoa whare herehere e hiki ake ana i te ara iahiko ki te pae o nāianei i te wā e whakakīkī ana te tīwiri. Ka whakaaetia e tēnei hoahoa ngā waea totoka, ngā waea kua werohia, me ngā ara iahiko kua whakapirihia, kāore he whakaurunga urutau, koia te take e whakamahia nuitia ai te piko 5.0mm hei whakahou i ngā kaupapa ina kore e taea te matapae i ngā momo waea o nāianei.

Ngā Whakaritenga mō te Ngongo me te Whakawātea i te 1000V i te IEC 60947-7-1

Ehara i te mea uaua te toro me te ātea. I te 1000V, ka taea e te mura i waenga i ngā pou tata te whakangaro i te huihuinga PCB katoa. Ko te tawhiti 5.0mm e whakarato ana i te ātea hau tata ki te 5mm i waenga i ngā wāhanga kawe hiko, e tutuki ai ngā whakaritenga ātea mō te kāwai ngaohiko nui III i te 1000V i roto i ngā taiao ma. He roa ake te tawhiti toro i te mata kirihou nā te mea kei roto i te āhua o te poraka pito he arai, he awaawa rānei e akiaki ana i te ara turuturu ki te zigzag. Koinei te take e tohua ai e ngā kaihanga ngā whakatauranga parahanga tohu 2, 3 rānei i runga i te hoahoa whare. Kua kite ahau i ngā panera kua tāutahia ki ngā whare ahuwhenua i reira te kohikohinga puehu i whakaiti i te tawhiti toro whai hua mō ngā tau e rua, ka puta he rahunga aroturuki kāore i whakaarohia e te hoahoa taketake. E whakaaro ana te paerewa he taiao whakahaere. He onge te mahi tahi a te mooni.

Te Pūngao o 150A: Te Pūtaiao Rauemi kei Muri i te Whakatauranga

Ehara te whakatauranga 150A i te whakaaro noa. He rohe wera tēnei i tatauhia i raro i ngā tikanga motuhake: te pāmahana taiao o te 40°C, te whakairinga paparanga kotahi, me te kore he pūtake wera tata. Hurihia tētahi o aua taurangi, ā, ka heke te kaha tūturu. Ko te pae au i roto i te poraka pito he parahi, he koranu parahi rānei, ā, he mea nui te rerekētanga o te kawe hiko. Ko te koranu parahi he 60% te ihirangi parahi, e mau ana i te 75% o te kawe hiko o te parahi parakore. I te 150A, ko taua ngoikoretanga 25% ka huri hei whakamahana joule tāpiri i roto i te poraka pito, kāore e taea te memeha ngāwari. Ko te tīwiri tonu he maitai me te whakakikorua konutea, he aukati wera tēnei nā te mea he kino te kawe wera a te maitai ki te parahi. Ko te pikinga o te pāmahana i te pūwāhi pa i waenga i te waea me te pae au ka tīmata ngā pakaru. Ko te Ngā Paerewa IEEE mō ngā taputapu tohatoha hiko ka whakaratohia he aratohu tāpiri mō te whakahaere wera me ngā tātaitanga kiato iahiko e tautoko ana i ngā whakatakotoranga rauemi IEC.

Te Arahi Tinana Parahi me te Parahi me te Hurihanga Ā-Mīhini

Ko te parahi te mea nui rawa atu i roto i te umanga poraka pito nā te mea he pai te mahi miihini, he ātete ki te waikura, ā, he iti ake te utu i te parahi. Ko te painga ko te kawe hiko. I te kawenga tonu 150A, ka wera ake te pae au parahi me te 2.5mm te wāhanga whakawhiti i te pae parahi ōrite. Ehara i te mea kino te rerekētanga, engari ka kohia. I roto i te panera me te rima tekau poraka pito e kawe ana i te au tata-whakatau, ka taea e te kawenga wera kohikohi te whakanui ake i te pāmahana taiao o roto mā te 15°C, neke atu rānei, ka whakaheke i ia poraka i te wā kotahi. Kei te wātea ngā pae au parahi i roto i ngā raupapa kounga teitei, engari he nui ake te utu, ā, me whakakikorua te nikara hei ārai i te waikura. Ko te whakarerekētanga i raro i te taipana tīwiri tētahi atu āhuatanga. Ko te parahi ka puta i te taipana iti iho i te parahi, ko te tikanga ka whakarerekē te hononga miro i te whakakī rawa, ā, ka hanga he hononga wetewete i muri i ngā marama e ono. Kua wahia e au ngā poraka pito kua pakaru i te wāhi i kitea ai te pakaru o te miro parahi. I whakamahia e te kaiwhakauru te taipana kotahi e whakamahia ana e ia ki ngā poraka tinana-rino. Kāore te rauemi e muru i taua whakaaro.

Ngā Whakatakotoranga Taipana Tīwiri me ngā Hapa Tāutanga Marae

Ko te momo rahunga tino kitea i roto i ngā poraka pito tīwiri ko te taipana-iti, te taipana-nui rānei. Ka waiho e te taipana-iti he āputa i waenga i te ara iahiko me te pae iahiko. Ka piki ake te ātete pa, ka tere ake te waikura i te wera ā-rohe, ā, ka pakaru te hononga i te mutunga nā te rere wera. Ka tangohia te miro e te taipana-nui, ka whakapēhia te ara iahiko, ka pakaru rānei te whare. Ko te whakatakotoranga taipana kua tāia ki te pepa raraunga he 0.5 ki te 0.8 Nm mō ngā poraka pitch 5.0mm. Ko te nuinga o ngā kaimahi hiko kāore he tīwiri taipana kua whakatikatikaina ki ngā mita-Newton. Ka whakakīkī rātou kia piri rawa. He hē taua whakatau whaiaro tata ki te hautoru o te wā, i runga i aku rangahau kore mana o ngā kapa tiaki. Ko te reiti hapa tāutanga mara te mea ngaro paru o te umanga poraka pito. E whakaaro ana ngā kaihanga he tino tika te tāutanga. He mōhio ake ngā kaihanga panera.

Pūmau Tīwiri me te Puna Pana-Whakauru: Te Tauhokohoko Wiri

He tere ake te tāuta i ngā pito puna pana-roto. Koinā te uara katoa o aua pito. Ka tangohia e koe te waea ka pana ki roto. Kāore he tīwiri, kāore he āwangawanga mō te taipana, kāore he tango miro. Ko te utu ko te kaha o te au me te ātete wiri. Ka whakawhirinaki ngā hononga puna ki te kaha miihini pumau e whakamahia ana e te topenga maitai puna kua hangaia. He rawaka taua kaha mō ngā tāutanga tūmau i roto i ngā taiao e whakahaerehia ana te āhuarangi. I roto i ngā panera whakahaere motuka ahumahi, ko te wiri te hoariri. Ka puta te wiri tonu i ngā pūwero, ngā papu, me ngā kaikawe e whakangoikore ana i te maitai puna i roto i te wā. Ka heke te kaha pa. Ka piki te ātete pa. Ā tōna wā ka pakaru te hononga. Ka pupuri te whakapiri tīwiri i te kaha pa mā te pēhi miihini o te kaiārahi ki te pae au. Kāore te hononga tīwiri kua tika te taipana e wetekina i raro i te wiri 5g nā te mea ko te waku i roto i te hononga miro he nui ake i te kaha nekehanga wiri. Ehara tēnei i te ariā. Koia te take e whakamahia tonutia ai e ngā rūma pūwero ngā pito tīwiri.

Te Penapena Wā-Tāpiri me te Whakatapunga Pūmanawa o Nāianei

E 8 hēkona te penapena a te pūnga pana-whakauru mō ia waea, ki te whakaritea ki te pūnga tīwiri. I roto i te panera me te 200 ngā pito, he 27 meneti te roa o te mahi. Mō ngā kaihanga panera nui-rahi, he tino penapena mahi. Engari he iti ake te kaha o te iahiko. He iti te horahanga o ngā hononga puna ki te whakaritea ki te whānui o te pēhanga mata o te rawhi tīwiri. I te 150A, me nui rawa te horahanga o te puna kia mau tonu ai te mātotoru iahiko haumaru. Ko te nuinga o ngā pūnga pana-whakauru ka eke ki te 32A, ki te 41A rānei mō tēnei take. Ko te whānui 5.0mm me te whakatauranga 150A kāore e wātea ana i roto i te āhua pana-whakauru. Kāore e taea e te ahupūngao. Me nui rawa te puna kia kore ai e uru te whare ki te mokowā 5.0mm. Koia te take e noho tonu ai te tohatoha mana i tēnei taumata iahiko hei rohe o te rawhi tīwiri.

Ngā Whakamahinga Utaina Mōta: He aha te Pūmautanga o te Tīwiri e Ora ai i te Wiri 5g

Ko ngā papa whakahaere motuka te wāhi e tino kino rawa atu ai te wiri i roto i ngā whakaurunga hiko ahumahi. Ka puta he wiri taketake i te 30 Hz i te motuka 50 horsepower e rere ana i te 1800 RPM, me ngā haurore mai i te kakahu o te peera me te kore taurite o te whitiki. KĀORE E mōhiotia ana tēnei e ngā paerewa mō ngā pokapū whakahaere motuka mā te tautuhi i ngā whakaritenga ātete wiri e whakamaoritia ana ki ngā paearu whiriwhiri poraka pito. Ka taea e te poraka pito tīwiri me te pitch 5.0mm me te whakaora totoro waea tika te ora i te wiri sinusoidal 5g i raro i te IEC 60068-2-6 whakamātautau nā te mea he pūmau te kaha piri, ā, kāore e whakawhirinaki ki ngā āhuatanga ngenge ngāwari. He rerekē, ka pāngia ngā pito puna e te ahotea huringa i runga i te huānga puna tonu. Ka utaina, ka wetewetehia hoki te puna e ia huringa wiri. Neke atu i te miriona huringa, e tutukihia ana e te motuka i roto i ētahi wiki o te mahi, ka werawera, ka pakaru rānei te puna. Kāore te rahunga e tere tonu. He hekenga puhoi e puta mai ana hei piki ātete whakapā wā poto, kātahi ka wera, kātahi ka ngenge. Kāore he puna o te pito tīwiri ki te ngenge. Koinei tōna painga matua i roto i ngā kawenga motuka.

Ngā Whakaritenga Tiwhikete mō te Kaweake Tohatoha Hiko o te Ao

Ko te kaweake i ngā taputapu tohatoha hiko me whakatere i roto i te arai o ngā whakaritenga tiwhikete e rerekē ana i ia rohe me ia tono. He wāhanga te poraka pito, ehara i te hua whakamutunga, engari me mau ngā tohu tika, ki te kore ka kore e tirohia te huihuinga katoa. Mō te tohatoha ā-ao, ko ngā anga tiwhikete matua e rua ko te UL 1059 mō Amerika Te Raki me te IEC 60947-7-1 mō te toenga o te ao. Kāore e taea te whakawhiti. Kāore te poraka pito kua whakamanahia ki ngā paerewa IEC e tutuki aunoa i ngā whakaritenga UL, me te ritenga kē. He rerekē ngā kawa whakamātautau i roto i te whakarite waea, te roa o te huringa o nāianei, me ngā whakaritenga ātete mura. Ka taea te tiwhikete takirua engari he utu nui. Ka utua e te kaihanga ngā kaupapa whakamātautau e rua, ngā arotake wheketere e rua, me ngā utu tirotiro tonu ki ngā tinana e rua. Mō tētahi kamupene pēnei i a Ningbo J-Guang Electronics, ko te whakatau ki te whai i te tiwhikete takirua e whakawhirinaki ana ki te ranunga kaweake. Mena ko te mākete ūnga ko Ūropi me Āhia ki te Tonga-mā-rāwhiti, ka ranea pea te tiwhikete IEC anake. Mena kei te whakamaherehia te tohatoha o Amerika Te Raki, he mea whakahau te whakamana UL.

UL 1059 vs IEC 60947-7-1: Te Utu me te Wātaka Tiwhikete Takirua

Te UL 1059 Ko te paerewa mō ngā poraka pito e hiahia ana kia whakamātautauhia te pikinga pāmahana i te 1.2 ngā wā o te iahiko kua whakatauria mō tētahi roanga motuhake, me te whakamātautau ātete hiko-kore i te 2200V mō te 1 meneti. Ka whakamahia e te whakarite waea ngā momo ara iahiko motuhake kāore pea e rite ki te waea aho ngāwari e kitea ana i roto i ngā whakaurunga Pākehā. Ka whakamahia e te IEC 60947-7-1 he arorau whakamātautau ōrite engari he rerekē ngā momo waea me ngā tawhā roanga. Ko te tukanga tiwhikete takirua e 12 ki te 16 wiki te roa mēnā ka whakamātautauhia e ngā tari e rua te whānau hua kotahi i te wā kotahi. Ko te utu he tata ki te $15,000 ki te $25,000 mō ia raupapa hua mō te tiwhikete tuatahi, me ngā utu tirotiro ā-tau o te $3,000 ki te $5,000 mō ia tohu. Mō tētahi kaihanga poraka pito me te whānuitanga o te putea, ka akiakihia e tēnei hanganga utu ngā kōwhiringa rautaki mō te raupapa hei tiwhikete. Ko te papa 5.0mm me te whakatauranga 150A he raupapa matua mō te tiwhikete takirua nā te mea e aro ana ki te tohatoha hiko ahumahi, te wāhi e kaha rawa ana te tono o te ao, ā, ko ngā arai ture teitei rawa atu.

Ngā Poraka Whakamutunga CE-Anake me te Mōrearea Whakakorenga 480V o Amerika Te Raki

Kāore te tohu CE anake e āhei ai te mākete ki Amerika Te Raki. Heoi, kei te kite tonu ahau i ngā kaihanga panera Pākehā e ngana ana ki te kaweake i ngā poraka pito CE-anake ki te United States me Canada, me te whakaaro kei te whai mana te tohu CE. Kāore. I Amerika Te Raki, ko ngā pūnaha ahumahi 480V te paerewa. Ko ngā waehere hiko ā-rohe e hiahia ana kia rārangihia, kia mōhiotia rānei ngā wāhanga e te Taiwhanga Whakamātautau Whakamōhiotia ā-Motu (NRTL), ko te UL, ko te CSA rānei te tikanga. Ka whakakahoretia te poraka pito CE-anake e te Mana Whakahaere (AHJ) i te wā tirotiro. Me whakakapi e te kaihanga panera ngā poraka pito, me rapu rānei i tētahi aromatawai mara, he nui ake te utu i te tiwhikete-mua, ā, ka whakaroa i ngā kaupapa. Kua kite ahau i tēnei hapa i pau i tētahi kaihanga Pākehā he kirimana $2 miriona nā te mea i tae mai ngā poraka pito ki te papaanga, ā, i whakakahore te kaitirotiro ki te tango. Ehara te tohu CE i te uruwhenua ā-ao. He tauākī ture ā-rohe me te whānuitanga motuhake. Me manatoko e ngā kaihoko poraka pito e mahi ana i te ao te putea tohu i mua i te tuku i te ota.

Te Wiri me te Huringa Wera: Te Whakamātautau Ora Tere

Kāore te whakamātautau taiwhanga e tārua i te ao tūturu, engari ka taea te matapae i ngā momo rahunga mena ka whiriwhiria ngā kawa whakamātautau me te mohio. Mō ngā poraka pito i roto i te tohatoha hiko ahumahi, ko ngā whakamātautau tere e rua e tino whai tikanga ana ko te wiri me te huringa wera. Ka whai te whakamātautau wiri i te IEC 60068-2-6, e tohu ana i ngā wiri sinusoidal mai i te 5 Hz ki te 150 Hz i ngā taumata whakatere kua tohua. Ka tauwhitiwhiti ngā whakamātautau huringa wera i waenga i ngā pāmahana teitei me te pāmahana iti, ko te tikanga -40°C ki te +85°C mō ngā hua ahumahi, me ngā wā noho e taea ai e ngā rauemi te eke ki te taurite wera. Mā te whakakotahitanga o ēnei whakamātautau ka kitea ngā momo rahunga e ngaro ana i te whakamātautau ahotea kotahi. Ka rahunga pea te poraka pito e whiti ana i te wiri i te pāmahana rūma ina whakamahia te wiri kotahi i te 85°C nā te mea ka ngawari te whare kirihou, ka wetekina te hononga miro.

IEC 60068-2-6 Te Kawa Whakamātautau Wiri me ngā Raraunga Rūma Pūhiko o te Ao Tūturu

He tūāpapa te kawa whakamātautau IEC 60068-2-6, ehara i te tuanui. He maha ngā wā ka hipa ake ngā rūma pūwero tūturu i ngā tikanga whakamātautau. Ka taea e te pūwero tauutuutu i roto i te tipu whakamatao te whakaputa i ngā tihi wiri i te 10g i te papa whakairi, e kukū ana i ngā auau motuhake e whakawhirinaki ana ki te tere o te pūwero me te whakaritenga o te rango. Ka rongohia tēnei wiri e ngā poraka pito e mau ana ki runga i te maitai hanganga kotahi mā roto i te anga papa. E whakaatu ana ngā raraunga mara mai i ngā tipu whakamatao he iti iho i te 1% te tere rahunga o ngā poraka pito tīwiri me te piko 5.0mm me te whakaora taumahatanga waea tika i roto i ngā tau e rima. Ko ngā poraka pito puna i roto i te taiao kotahi e whakaatu ana i te 8% ki te 12% ngā reiti rahunga i roto i te wā kotahi. Ehara te rerekētanga i te whakamātautau paerewa. Ko te rerekētanga ko te tawhiti i waenga i te whakamātautau paerewa me te taiao tūturu. Mā te here tīwiri e whakarato taua tawhiti. Kāore ngā pito puna.

Ngā Aratau Rahunga Pahikara Wera: Mai i te Wetekina o te Tīwiri ki te Ātete Pa

Ka puta te pakaru i te huringa wera mā te rerekētanga o te whakawhanuitanga wera. Ka horapa te tīwiri maitai, te pae au parahi, me te ara iahiko parahi i ngā tere rerekē i te huringa o te pāmahana. I roto i te hononga kua tika te whakawhanui, ka uru te pēhanga ngāwari o ngā rauemi ki tēnei whakawhanuitanga rerekē. Ina iti te whakawhanuitanga o te hononga, ka puta he nekehanga iti i waenga i te ara iahiko me te pae au i ngā huringa wera. Ka waikura te mata pa. Ka piki ake te ātete pa. Ka wera ake te hononga i te huringa e whai ake nei. Ka tere ake te tukanga. I roto i ngā whakamātautau huringa wera, ka taea e te hononga kāore i te tino whakawhanui te eke ki te 150% o tōna ātete pa tuatahi i roto i te 500 huringa. Ka whakaatuhia e te hononga kua tika te whakawhanui he iti iho i te 10% te pikinga i muri i te 1000 huringa. Ka taea te matapae i te aratau pakaru. Ka taea hoki te matapae i te ārai: te whakawhanuitanga tika me te whakarite waea tika. Ko te raruraru, kāore te matapae e whakamana i te whakatutukitanga i runga i te papa wheketere.

Me pēhea te Tauwhāiti i ngā Poraka Whakamutunga mō te Whakahoutanga o te Paewhiri Mana Mōta

He herenga tā ngā kaupapa whakahou kāore e pā ki ngā hoahoa hou. He pumau ngā roa waea o nāianei. He pumau ngā tapahi o te panera. Ka inehia te wā whakatā i roto i ngā hāora, ehara i te rā. Ina tohua ngā poraka pito mō te whakahounga o te panera whakahaere motuka, ko te herenga tuatahi ko te hototahi ā-ahu. Mena he 5.0mm te whānui o ngā poraka pito o nāianei, me ōrite te whakakapinga, me huri rānei te tahora PCB. Ko te herenga tuarua ko te ine waea. Ko ngā kaiārahi o nāianei he 10AWG, he 12AWG rānei, ā, me whakaae te whakakapinga ki a rātou me te kore e whakamutua anō. Ko te herenga tuatoru ko te kaha o nāianei. Kāore e taea e te whakahounga te whakaheke i te whakatauranga. Mena i whakamahia e te panera taketake ngā poraka pito 150A mō ngā ara iahiko whāngai, me ōrite te whakakapinga ki taua kaha. Ko te herenga tuawhā ko te tiwhikete. Mena kei roto te panera i tētahi whare whakahaere, me mau ngā poraka pito whakakapinga i ngā tohu rite ki ngā mea taketake. Me manatoko hoki e ngā kaihanga panera kua tutuki te huihuinga PCB. IPC-A-610 ngā paerewa whakaae mō ngā hononga whakarewa me te whakairinga wāhanga, nā te mea ko te pono o te poraka pito ko te PCB e whakairihia ana. Ko te poraka pito tīwiri PCB 5.0mm te whānui me te whakatauranga 150A me te tiwhikete takirua te nuinga o te wā ko te kōwhiringa anake e tutuki ai ngā herenga e whā i te wā kotahi. Koia te take he taonga paerewa mō ngā kaituku e mahi ana ki te mākete tiaki ahumahi.

He aha te ine mōrahi o te waea mō te poraka mutunga 5.0mm?

Ko te nuinga o ngā poraka pito tīwiri PCB 5.0mm te whānui ka whakaaetia ngā ara iahiko tae atu ki te 10AWG (6mm²). Ko ētahi raupapa me ngā whare roa ka taea te whakauru i te 8AWG (10mm²), engari ko te awhe paerewa ko te 14AWG ki te 10AWG. Tirohia te pepa raraunga motuhake mō te awhe waea.

Ka taea e au te whakamahi i ngā ferrules me ngā poraka mutunga tīwiri?

Āe. Ka whakapai ake ngā whiri i te kounga whakamutu mō ngā ara iahiko kua takai, ā, ka ārai i te horapa o ngā ara iahiko. Kua hangaia te tikanga rawhi tīwiri i roto i te nuinga o ngā poraka piko 5.0mm kia whakaaetia ngā ara iahiko kua takai, me te kore e whakarerekētia. Me ōrite te whānui o te whiri ki te whānuitanga o te waea poraka pito.

He aha i wera ai taku poraka matihiko i te 80A ina kua whakatauria mō te 150A?

Ko te whakatauranga 150A e whakaaro ana ki ngā āhuatanga motuhake: 40°C te pāmahana taiao, te whakamau paparanga kotahi, me te taipana tika. Mena he kī tonu te panera, he teitei ake te pāmahana taiao, he hē rānei te taipana, ka heke te kaha tūturu. Inehia te pāmahana ki te pūrua wera i te pūwāhi pa. Mena ka neke ake i te 45°C te pikinga i runga ake i te pāmahana taiao, tirotirohia ngā āhuatanga tāutanga i mua i te whakapae i te hua.

Me whai tiwhikete takirua ahau mō te kaweake ki Mexico?

E whakaae ana a Mehiko ki ngā paerewa NOM me te ao whānui. Mō ngā taputapu ahumahi, me whai tiwhikete NOM, engari he maha ngā wā ka taea te whakamahi i tētahi poraka whakamutunga me te whakamanatanga UL hei wāhanga e mōhiotia ana i roto i tētahi huihuinga kua whakamanahia e te NOM. Ko te whakaritenga motuhake ka whakawhirinaki ki te kāwai hua whakamutunga. Whakawhitiwhiti kōrero ki tētahi whakahaere tiwhikete ā-rohe mō ngā aratohu whakamutunga.

Ko tēhea tīwiri taipana me whakamahi mō ngā poraka mutunga 5.0mm te whānui?

He tika te whakamahi i tētahi tīwiri taipana kua whakatikatikaina me te awhe 0.1 ki te 1.0 Nm. Ko te whakatakotoranga noa ko te 0.5 ki te 0.8 Nm. Kaua e whakamahia he taraiwa hiko me te mamau paheke ki te kore te mamau e whakatikatikaina, e manatokohia ana hoki, nā te mea ka taea e te wiri o te taraiwa te wetewete i ngā pito tata.
