TL;DR — Ngā Mea Me Mōhio Koe
- Ngā poraka whakamutunga taumaha, 150A te whakatauranga, me te waea 35mm² (AWG 2) e whakaaetia ana koinei te paerewa mō te tohatoha hiko o te pokapū whakahaere motuka — e whakarato ana i ngā pūwāhi hononga haumaru, whakarite hoki mō ngā taura whāngai motuka tae atu ki te 50mm².
- Ko ngā iahiko tomo o te motuka (6-8× FLA) e hiahia ana ki ngā poraka whakamutunga me te papatipu wera nui — ka rahua ngā poraka mana whakahaere paerewa kua whakatauria ki te iahiko pumau ōrite i raro i ngā huringa mahi MCC nā te mea kāore i a rātou te wāhanga whakawhiti parahi hei mimiti i te pūngao urunga mai.
- Ko te wāhi reka 35mm² (AWG 2) ehara i te mea tūpono noa: he tino taurite te kaha (150A me te tawhē haumaru 25% i te 40°C), te whakahaere waea miihini (te pūtoro piko
- Tika mai i tā mātou wheketere, he 35-50% te iti iho o te utu mō ngā poraka pito mahi taumaha i ngā waitohu Pākehā kua whakamanahia e te IEC/UL — me ngā wā tuku mō ngā hua putumōhio paerewa o te 2-3 wiki.
- Ko te whakaritenga SCCR te mōrearea #1 mō te tutuki i ngā whakaritenga i roto i te kōwhiringa poraka whakamutunga MCC — me manatoko tonu kei te ōrite te whakatauranga iahiko poto o te poraka pito ki te SCCR whānui o te MCC (ko te tikanga he 42kA ki te 65kA mō ngā taputapu hou).
He aha te Whakamārama i te Poraka Whakamutunga Taumaha mō ngā Pokapū Whakahaere Mōta?
Kia mārama ake ahau ki te tikanga o te kupu "heavy duty" — nā te mea he maha noa iho ngā whakamahinga o tēnei kupu i roto i tēnei umanga. Ko te poraka matihiko taumaha, e ai ki tētahi whakamāramatanga whai tikanga, he mea i hangaia mō ngā whakatauranga iahiko tonu mai i te 100A ki te 400A, me ngā awhe whakaaetia waea e tīmata ana i te 10mm² (AWG 8) tae atu ki te 150mm² (300 kcmil). Ehara ēnei i ngā poraka whakamutunga e whakamahia ana e koe mō ngā hononga PLC I/O, ngā koropiko taputapu 4-20mA rānei. Koinei ngā poraka e noho ana i waenganui i te pahi matua MCC me ngā waeine tīmatanga motuka takitahi — arā, ko ngā mea e kawe ana i te iahiko e ranea ana hei whakahaere i tētahi motuka whakapūngao 75kW (100 HP).
I tō mātou wheketere, ka tuhia e mātou he rārangi mārama: Mena kei te whakahaerehia e te poraka pūrua te mana whāngai motuka — ehara i te mana whakahaere, ehara i te waea tohu, engari ko te mana toru-wāhanga e huri ana i te motuka — ka taka ki roto i tā mātou kāwai hua mahi taumaha. He take hangarau motuhake tēnei e tū ai: e toru ngā ahotea hiko e whakaatuhia ana e ngā ara iahiko motuka, kāore e taea e ngā ara iahiko whakahaere, ā, me whai whakaaro te hoahoa poraka taunga ki ngā ahotea e toru i te wā kotahi.
He aha ngā Poka Whakamutunga Rerekē e Hiahiatia ana e ngā Poka Whakahaere Motuka
Ko ngā pokapū whakahaere motuka, i runga i te hiko, tētahi o ngā taiao tino kino mō ngā hononga poraka taunga. I ako ahau i tēnei akoranga i te tau 2012 i te wā i kōrero ai tētahi o ā mātou kiritaki tuatahi mō ngā pakaru o te poraka pito i roto i te tāutanga MCC i muri i ngā marama e waru noa o te whakahaeretanga — ngā poraka kua paahitia e rātou ngā whakamātautau katoa o te wheketere me te angitu. I te wā i rere atu ai tā mātou miihini ki te papaanga (he wheketere huihuinga motuka i Michigan), i kitea e mātou te raruraru i roto i te 15 meneti: He tino rawaka ngā poraka whakamutunga mō te whakahaere i te 120A āhua pumau, engari i pāngia rātou e ngā pikinga pikinga o te 720A e ono ngā wā i te hāora i te mea e haere tonu ana, e whakaweto ana hoki ngā motuka raina whakaputa.
Nā taua haerenga kotahi ki te mara i tino whakarerekē te āhua o tā mātou hoahoa me te aromatawai i ā mātou poraka taunga taumaha. Anei ngā mea e hiahiatia ana e ngā taiao MCC kāore e taea e ngā poraka taunga paerewa te whakatutuki:
Te Au Puku: Te Kaikōhuru Huna
E 6-8 ngā wā ka kumea e ngā motuka whakaauaha te kaha o te amperage kawenga-katoa (FLA) i te wā e tīmata ana — ka kumea e te motuka 75kW me te FLA 140A te 840-1120A mō te 2-5 hēkona pea i te wā e tīmata ana puta noa i te raina. Ahakoa te whakawhāititanga o te tere whakaurunga ki te 3× FLA e ngā tīmatanga ngohengohe, kei te titiro tonu koe ki te 420A e pupuhi ana mā te hononga poraka pito. Nā te mea ka whakamatautauria ngā poraka pito paerewa mō te mahi wera i te iahiko whakatauranga anake, kaua mō te taumahatanga poto-wā, kāore i te nui te wera o te wāhanga parahi hei mimiti i te kaha urunga mai me te kore e neke ake i te pāmahana whakangawari o te whare PA66.
Te Wiri: Te Kaiwhakakore Hononga
Kī tonu ngā MCC i ngā whakapā hiko-mīhini e katia ā-tinana ana, e tuwhera ana hoki i ngā mano tini wā i te rā. Ka tukuna e ia mahi whakapā he ru miihini puta noa i te hanganga wāhanga poutū katoa — ā, ka pāngia e ia poraka pito e mau ana ki taua hanganga. Ka āta wetekina ngā poraka pito tīwiri paerewa me te taipana whakakaha 1.2-1.5 Nm i raro i tēnei wiri. Ka whakamahia e ngā poraka taumaha ngā tīwiri maitai M5, M6 rānei me te taipana 2.5-5.0 Nm, ā, kei roto i te āhua o te tīwiri he āhuatanga raka-ake (he horoi puna kōniko, he mata pa niho rānei) e ārai ana i te hurihuri i raro i te wiri.
Wāhi Herekore me te Whakamahana
He kikī rawa ngā wāhanga poutū o te MCC: ko ngā pae pahi, ko ngā kaiwawao ara iahiko, ko ngā kaiwhakapā, ko ngā whakawhiti taumaha, ko ngā whakawhiti mana whakahaere, me ngā poraka pito ka whakataetae katoa mō te wāhi i roto i te whare NEMA 1, NEMA 12 rānei. Ko te pāmahana taiao i roto i te MCC e whakahaerehia ana ka eke ki te 50-55°C — 10-15°C teitei ake i te paerewa whakatauranga 40°C mō ngā poraka pito. I te pāmahana taiao 55°C, me whakaheke te whakatauranga iahiko whai hua o te poraka taunga mā te 12-15%, ko te tikanga ka noho te whakatauranga pereti ingoa 150A hei kaha tonu 128-132A. He nui ake te tawhē wera o ngā poraka mahi taumaha me ngā pae parahi nunui mō tēnei āhuatanga.
Te Awhe Waea 35mm² (AWG 2): He aha i waiho ai tēnei hei Paerewa MCC
Kei te wāhi e tū ai te ara iahiko 35mm² ki te hononga o ngā here hangarau e toru e hono ana ki te hoahoa pokapū whakahaere motuka. Ehara i te tau matapōkere — he hua tēnei o te arotautanga o te kaha, te whakahaere miihini, me te utu.
| Tawhā | 25mm² (AWG 4) | 35mm² (AWG 2) | 50mm² (AWG 1/0) |
|---|---|---|---|
| Te kaha i te 40°C (parahi, arataki-toru i roto i te paipa) | 110A | 145A | 170A |
| Te kaha i te 55°C (MCC roto, kua whakahekehia) | 93A | 123A | 144A |
| Te tawhē haumaru i runga ake i te whakatauranga poraka 150A | -26% ❌ | +21% ✅ | +42% (rahi rawa) |
| Te whānui o waho o te taura (kua whakamātaotia ki te XLPE) | ~14mm | ~16mm | ~19mm |
| Te pūtoro piko iti rawa (mō ia NEC) | ~98mm | ~112mm | ~133mm |
| Te utu mō ia mita (whakatairanga) | 0.75× | 1.00× | 1.40× |
E whakamārama mārama ana te ripanga i te pūrākau: 35mm² te ara iahiko goldilocks mō ngā ara iahiko motuka 150A. He iti rawa te taura 25mm² mō te 150A i ngā pāmahana MCC teitei — ka whakawhirinaki koe ki te taha wera o te poraka taunga hei whakakapi i te iti o te kawe hiko, he mahi hangarau ngoikore tēnei. He haumaru te taura 50mm² engari he rahi rawa — he 40% te utu, he nui ake te wāhi e hiahiatia ana mō te piko, ā, kāore he painga mō te mahi hiko nā te mea ko te poraka taunga tonu te mea whakawhāiti i te 150A.
Ngā Hangarau Hononga mō ngā Taupānga Taumaha
Ina whakamutua e koe te taura whāngai motuka 35mm² i roto i te MCC, He rite te hiranga o te hangarau hononga ki te whakatauranga o te poraka taunga. E whā ngā momo hononga motuhake e hangaia ana e mātou mō tā mātou raina hua taumaha, ā, he whakamahinga motuhake tā ia momo:
Hononga Tūhono/Pūtu (E taunakitia ana mō te ≥35mm²)
Ka taea te whakamahi i ngā pito mowhiti whakapiko ki tētahi pine maitai M6, M8 rānei kua mirohia me te nati hexagon me te horoi puna. Koinei tā mātou taunakitanga tino kaha mō tētahi kaiārahi 35mm², neke atu rānei, inā koa mō ngā hononga taha-raina (taumai) i roto i ngā tono MCC. He tino whai kiko ngā take: ka taea e te pito mowhiti te huri i te hononga 360-tohu huri noa i te pou, ka ātete te hononga miihini ki te wiri ina tika te whakapiko, ā - he mea nui mō te tiaki - Ka taea te momotu me te hono anō i te pito mowhiti i ngā wā maha, me te kore e whakaiti i te kaha o te ara iahiko, he mea tino nui tēnei ina hiahiatia te whakawhiti i ngā peere MCC i te wā e whakarerekētia ana ngā raina whakaputa.
Rawhi Tīwiri Mana (Mō te 10-35mm²)
Ka peia e te tīwiri maitai M5, M6 rānei tētahi pereti pēhanga e pēhi ana i te ara iahiko ki te pae iahiko parahi. Koinei tā mātou momo hononga rongonui mō ngā pito whāngai motuka i te awhe 10-35mm² nā te mea e whakakotahi ana i te tāutanga tere (i raro i te 30 hēkona mō ia waea me te tīwiri hiko) me te pono roa. Ka whakamahia e te tīwiri te 3.0-4.0 Nm o te taipana — he nui hei whakapiri makariri i ngā aho ara iahiko ki te mata pa parahi whakakikoruatia ki te tine, ka hanga he hononga piri-hau e ātete ana ki te waikura me te paheketanga huringa wera.
Rawhi Pouaka/Rawhi Nohoanga (Mō ngā Momo Arataki Whakauru 16-50mm²)
Mā te rawhi nohoanga āhua-U me ngā tīwiri e rua ka taea te rawhi motuhake i ngā taha e rua o te ara iahiko. He mea nui tēnei hoahoa ina whakamutua ngā taura motuka konumohe i te taha o ngā taura whāngai parahi — nā te mea ka uru ki roto ngā tauwehenga whānui wera rerekē o te konumohe (23×10⁻⁶/K) me te parahi (17×10⁻⁶/K) me te kore e puta he wāhi wera i te atanga whakapā.
Ngā Poraka Tūhono Tohatoha Hiko (Mō ngā Hononga Pahi Matua)
Koinei ā mātou poraka nui rawa atu, me ngā titi miro M10, M12 rānei kua whakatauria mō te 250-400A. Ka whakamahia ēnei ki te wāhi e hono ai te pae pahi poutū o te MCC ki ngā taura whāngai e haere mai ana — te pūwāhi hononga tuatahi rawa atu i te pokapū whakahaere motuka. I tēnei taumata o nāianei, ka noho te poraka pito hei wāhanga hanganga, ehara i te mea he hononga hiko noa iho — ko ngā kaha ā-pūkaha mai i te piko o te taura 150mm² me tautoko e te whare poraka pito me tōna whakamau reera DIN, kaua e te pou parahi anake.
Ngā Tiwhikete: Ngā Mea e Hiahiatia ana e tō Whakatakotoranga MCC
Kāore i te mārama ngā whakaritenga hoko mō te pokapū whakahaere motuka mō ngā whakaritenga tiwhikete poraka taupū. Mena kei roto i te whakatakotoranga he taputapu MCC kua whakarārangihia ki te UL 845 (pērā i ngā MCC ahumahi katoa o Amerika Te Raki), me mau te tohu rārangi UL tika ki ia wāhanga o roto — tae atu ki ngā poraka pūrua.
Mō ngā poraka pito mahi taumaha i roto i ngā tono MCC, ko ngā tiwhikete matua ko:
UL 1059 (Paerewa mō ngā Poraka Whakamutunga) — e kapi ana i ngā poraka taunga kua whakatauria ki te 1500V. Mō ia UL 1059 Putanga 6-2024, me whakamātauria ngā poraka pito mō te ātete hiko-kore, te pikinga pāmahana i te iahiko whakatauranga, me te ātete iahiko ara-poto. Ko ā mātou poraka taumaha kua whakarārangihia ki te UL he tohu SCCR mai i te 10kA ki te 65kA i runga i te whakaritenga o te taputapu tiaki o runga — ā, ka whakaratohia e mātou ngā ripanga whakaritenga SCCR i roto i ia pepa raraunga hua.
CSA C22.2 Nama 158 — te ōrite o Kanata, e hiahiatia ana mō ngā MCC kua tāutahia ki Kanata. Ka tāpirihia e te whakamātautau CSA he whakamātautau pānga makariri i te -35°C kāore e hiahiatia ana e te UL, he mea nui tēnei mō ngā tāutanga MCC o waho i ngā āhuarangi raki.
IEC 60947-7-1 — te paerewa o te ao. Mō ia te whakatikatika hou, me whakaatu mārama e ngā poraka pito te iahiko ātete-poto kua whakatauria (Icw) — te iahiko ka taea e te poraka te kawe mō te 1 hēkona me te kore e pakaru. Mō tētahi poraka mahi taumaha 150A, ko te uara Icw kei waenganui i te 3.0kA ki te 4.5kA (1 hēkona), me whakarite tēnei ki te kaha tuku-mā roto o te kaiwawao ara iahiko o runga o te MCC.
Te Kōwhiri i tētahi Kaiwhakarato Poraka Taumaha: He aha te Wehewehenga o te Kounga mai i te Whakakorenga
E hiahia ana ahau ki te kōrero tika mō tēnei kaupapa, nā te mea Kua kī tonu te mākete poraka taunga i ngā kaiwhakarato e tuku ana i ngā hua he rite tonu te āhua i roto i ngā whakaahua o te rārangi ingoa engari he rerekē rawa te mahi i raro i ngā āhuatanga whakahaere o te MCC.
Anei ngā mea kua akohia e mātou e wehewehe ana i tētahi poraka taunga taumaha kounga teitei mai i tētahi poraka taunga taonga — me ngā mea me manatoko e koe ina aromatawai ana i tētahi kaiwhakarato poraka tauranga mahi taumaha:
1. Tiwhikete parakore parahi. Kei roto i te pae parahi hiko C11000 tūturu ngā tuhinga e whakaatu ana i tōna hanganga mai i te whare whakapai parahi. Kei roto i te parahi rūpahu, i te parahi hangarua rānei — he mea tino noa i roto i ngā poraka pito iti te utu — ngā poke (ko te rino me te hāora te nuinga) e whakaiti ana i te kawe hiko mā te 5-15%, ā, ka hangaia he wāhi wera i ngā rohe kōpaka. Ka whakaratohia e mātou he tiwhikete whakamātautau mira mō ia puranga parahi e whakamahia ana i roto i tā mātou raina mahi taumaha.
2. Te matotoru o te whakakikorua tine. E rua ngā mahi a te whakakikorua tine i runga i te pae parahi: ka ārai i te waikura o te parahi (ka whakanui ake i te ātete pa i te roanga o te wā), ā, ka hanga he mata ngohengohe, he āhua rite ka honoa mātao ki te ara iahiko i raro i te pēhanga tīwiri. Ko te matotoru whakakikorua paerewa ahumahi he 3-5μm; ka tāpirihia e mātou he whakakikorua ki te 5-8μm nā te mea ka roa ake te wā tiaki waikura mai i te 5 tau ki te 15+ tau i roto i ngā taiao o roto e whakahaeretia ana.
3. Whakamātauria te tīwiri maitai me te whakamahana. Me mau tonu ngā āhuatanga hangarau o ngā tīwiri whakapūmau i roto i te poraka matihiko taumaha ahakoa ngā mano tini o ngā huringa wera mai i te -40°C ki te +130°C. E whakamahi ana mātou i ngā tīwiri maitai waro taumata 8.8 me te whakakikorua konutea-nikora me te paninga whakawhiti kōromate — ka whakaratohia e tēnei huinga te ātete waikura 5× o ngā tīwiri whakakikorua konutea paerewa, ā, ka mau tonu te kaha piri puta noa i te awhe pāmahana katoa.
4. Te hanganga o ngā rauemi whare. He maha ngā whare poraka taunga kua tohua ki te "PA66" me te kore e tohua te nui o te muka karāhe. Ko te ōrau whakakaha muka karāhe (te nuinga o te wā ko te 25%, 30 rānei%) ka pā tika ki te pumau o te āhua o te whare i raro i te wera — i te 130°C, ka mau tonu te kaha kume o te whare PA66 GF25 i te 40% o tōna kaha kume i te pāmahana rūma, ko te PA66 GF30 ia ka mau tonu te 55%. Mō ngā poraka taumaha e mahi ana i ngā pāmahana MCC teitei, ko te rerekētanga i waenga i te GF25 me te GF30 ko te rerekētanga i waenga i te whare e pupuri ana i te tika o te miro tīwiri me te whare kāore.
Te Whakauru i ngā Poraka Whakamutunga Taumaha ki roto i ngā Hoahoa MCC: Te Hangarau Whaihua
Neke atu i te tekau tau te roa o tā rātou tuku poraka pito ki ngā kaihanga MCC me ngā kaihanga panera, anei ngā taipitopito whakauru e wehewehe ana i te tāutanga ma me te moemoeā rapurongoā:
Te Whakamahere Wāhi Ara Waea. Ko te whānui o ngā wāhanga poutū o te MCC he 100-150mm te taha matau. Ko te huihuinga poraka pito mahi taumaha me ngā tūranga 12 i te piko 15mm e noho ana i te 180mm o te reera DIN — me te tāpiri i ngā radius piko taura mō ngā kaiārahi 35mm² ka tāpirihia he 110mm ki ia taha. Ko te tikanga o tēnei, ka pau te 400mm o te wāhi waea poutū i tētahi poraka 12-tūranga, me whai whakaaro ki tēnei i roto i te tuhi tahora wāhanga MCC i mua i te kukume i te waea tuatahi.
Te Whakahaere Wera. Ka puta he wera tata ki te 6-8W mō ia tūranga mai i te ātete pa me ngā mate I²R o te pae pahi, he huihuinga poraka pito 150A me ngā tūranga e 8, ā, ko te toharite o te 110A mō ia tūranga ka puta he wera tata ki te 6-8W mō ia tūranga — tata ki te 50-65W te tapeke. I roto i tētahi wāhanga NEMA 12 MCC kua hiritia, kāore he hauhautanga ā-kaha, ka ara ake te pāmahana o roto o te wāhanga e taua 65W mā te 5-8°C i runga ake i te pāmahana taiao i roto i tētahi huringa mahi e 4-hāora. Me tāpiri atu tēnei pikinga pāmahana tāpiri ki te tātaitanga whakahekenga pāmahana taiao — i roto i te mahi, he maha ngā wā ka whai hua te mahi a te poraka 150A i roto i te NEMA 12 MCC kua utaina katoatia hei poraka 135A.
Waea mai i te Poraka Whakamutunga ki te Tīmatanga. Ko te hapa waea e kitea whānuitia ana i te mara ko te whakahaere i ngā taura whāngai motuka mai i te poraka pūmau ki te tīmatanga motuka ma te whakamahi i ngā pekepeke iti. Mena he 35mm² te whānui o te poraka pito, ā, ka whakaaetia e te tīmatanga o te motuka he 35mm² ngā hononga, me 35mm² hoki te whānui o te hononga i waenganui i a rāua — kaua e 16mm², e 25mm² rānei nā te mea he māmā ake te piko i aua hononga. Ka wera ake te hiko o te peke 16mm² i roto i te ara iahiko 150A i te 30-40°C i ngā ara iahiko 35mm² i ia taha, ka waihanga i tētahi ngoikore wera e tohu haere ana ngā kaitirotiro.
Te Utu Katoa o te Mana Whakahaere: Neke atu i te Utu Hoko
Ko te utu mō ia wae te mea e aro nui ana ki ngā tīma hokohoko; ko te pono ia o ngā miihini tiaki. Mā te tātaitanga o te utu katoa o te mana pupuri ka honoa ēnei tirohanga — ā, i roto i ō mātou wheako, koinei te tautohe tino whakatenatena mō te haumi ki ngā poraka whakamutunga mahi taumaha kounga teitei.
Me tatau tātou i te TCO mō tētahi huihuinga poraka pito mahi taumaha 20-tūranga i roto i tētahi MCC — te whakarite i tētahi otinga kounga teitei a te kaihanga me tētahi taonga kawemai:
| Huānga Utu | Poraka Moni (J-Guang, Tika) | Kawemai Taonga |
|---|---|---|
| Te utu hoko huihuinga 20-tūnga | $48.00 | $28.00 |
| Te mahi tāutanga (2 hāora × $65/hāora) | $130.00 | $130.00 |
| Te tiaki ā-tau (tirotiro taipana anō, 0.5 hāora × $65/hāora) | $32.50 | $32.50 |
| Te tūponotanga o te rahunga i roto i te roanga ratonga 5-tau | 0.5% | 3.2% |
| Te utu mō ia takahanga rahunga (wā kore mahi + whakakapinga) | $2,800 | $2,800 |
| Te utu mō te korenga e tumanakohia ana mō ngā tau e 5 | $14.00 | $89.60 |
| Tapeke TCO 5-Tau | $354.50 | $410.10 |
E $20 te utu tāpiri mō te poraka moni nui i te tīmatanga, engari e $55.60 te penapena i roto i ngā tau e rima — he 2.8× te hokinga mai i runga i te haumitanga tāpiri. Kāore hoki tēnei tataunga e whakauru ana i te utu mō te wā whakatā whakaputa i te wā e whakakapia ana te poraka i rahua, ā, mō tētahi raina whakaputa e whakaputa ana i te $5,000/haora i roto i te moni whiwhi, ka tāpirihia he $10,000-20,000 mō ia takahanga rahua.
Ngā Pātai Auau
Q: Ka taea te whakamahi i ngā poraka mutunga mahi taumaha mō ngā taura motuka parahi me te konumohe?
Āe — engari me ngā āhuatanga hoahoa motuhake anake. Ko ngā ara iahiko konumohe e hiahia ana ki ngā poraka pito me ngā mata whakapā parahi whakakikoruatia ki te tine, ki te hiriwa rānei, me ngā tikanga hononga kua tohua mō te whakamahinga Al/Cu (bimetallic). Mō ia IEC 60947-7-1, me whakamātautau anō ngā poraka pito kua whakatauria mō ngā ara iahiko konumohe i te huringa wera (500 huringa i waenga i te 25°C me te 110°C) nā te mea ka nui ake te ahotea i te atanga whakapā nā te CTE teitei ake o te konumohe. Ka whakamahia e ā mātou poraka Al/Cu-rated ngā mata whakapā niho me ngā whakakā puna Belleville hei pupuri i te pēhanga whakapā tonu ahakoa te rerekētanga o te whānui wera o te ara iahiko konumohe.
P: He aha ngā mahi tiaki e hiahiatia ana mō ngā poraka taunga taumaha i roto i te ratonga MCC?
Ko te iti rawa o te whakaritenga ko te whakahou i ngā hononga tīwiri katoa i ia tau. Ka tūtohu anō mātou kia tirotirohia te pāmahana (te matawai kāmera infrared) i ngā wā kati tiaki ā-tau — ko te pikinga o te pāmahana neke atu i te 15°C i runga ake i ngā poraka pito tata e tohu ana kei te whanake haere te hononga ātete-teitei e hiahia ana kia arohia tonutia. Mō ngā poraka i roto i ngā wāhanga MCC wiri nui (mō ngā poraka he neke atu i te 10 ngā huringa ia hāora o ngā tīmatanga whakawhiti-aho), he mea tika kia tirotirohia ia ono marama i te tau.
P: E hia ngā poraka whakamutunga mahi taumaha ka taea te whakairi ki runga i te reera DIN kotahi i roto i te MCC?
Ko te mararatanga o te wera ngā mea whakawhāiti, ehara i te wāhi tūturu. Ka taea e te rēra DIN paerewa 1-mita i roto i te wāhanga poutū MCC te whakauru i te 40-50 ngā tūranga o ngā poraka mutunga mahi taumaha i te piko 20mm. Heoi, ki te mea kei te kawe katoa aua poraka i te iahiko tata-whakatau, ka taea e te putanga wera whakakotahi te neke ake i te kaha whakamatao kawe hiko taiao o te wāhanga. Ko tā mātou aratohu hangarau: kaua e neke atu i te 30 ngā tūranga mahi taumaha mō ia mita rārangi o te reera DIN mēnā kāore te wāhanga MCC e whakauru ana i te hauhautanga ā-kaha — ā, me wehe tonu ngā rōpū poraka au-teitei me te iti rawa kia rua ngā tūranga kau, ngā poraka tohu au-iti rānei hei hanga i ngā wehenga wera i te ara pahi.
P: Me rerekē ngā poraka whakamutunga mō ngā motuka whāngai-VFD me ngā motuka whakawhiti-aho i roto i te MCC kotahi?
Āe — ā, he kōrero tēnei e warewarehia ana. Kei roto i ngā ngaru putanga VFD ngā haunga auau-tiketike (ngā auau whakawhiti o te 2-16 kHz) e whakanui ana i te pānga kiri i roto i ngā kawe parahi, ā, e whakaputa ana i te whakamahana I²R tāpiri i roto i ngā hononga poraka pito. E ai ki ā mātou whakamātautau, me whakaheke te kaha o te poraka 150A e hono ana ki te putanga VFD e rere ana i te auau whakawhiti 8kHz ki te tata ki te 130A (he whakahekenga 13%) hei utu mō te whakamahana haurore tāpiri. Mena kei te whakaranu koe i te VFD me ngā tīmatanga whakawhiti-rāina i roto i te MCC kotahi, tohua ngā poraka whakamutunga i runga i te whakahekenga o te VFD kia rite ai te ōritetanga — he iti ake te utu ki te tohu nui rawa i te kotahi huinga poraka i te pupuri i ngā tūemi rārangi e rua.
Q: Kia pēhea te roa o te wā e tatari ana mō ngā whirihoranga poraka matihiko mahi taumaha ritenga?
Mō tā mātou raina hua taumaha paerewa (80A-400A), ka tukuna ngā hua o te rarangi pukapuka i roto i ngā rā pakihi e 5-7 mai i tō mātou whare i Ningbo. Ko ngā whirihoranga ritenga — te maha o ngā pou kāore i te paerewa, ngā whakatauranga iahiko whakauru, te waehere tae motuhake, te tohu ritenga — e 2-3 wiki te roa tae atu ki te whakaaetanga hangarau me te tirotiro tuhinga tuatahi. Ka pupuri mātou i te putunga parepare o ngā kōtaha paera parahi paerewa katoa me ngā pokepoke whare, nō reira ko ngā whirihoranga ritenga ka whakawhāitihia e te wā huihuinga me te whakamātautau, ehara i te wātea o ngā rauemi mata.

He aha a J-Guang hei Kaiwhakarato Poraka Taumaha mōu
E 15 tau mātou e hanga ana i ngā poraka pūkaha — mai i te tau 2010. I roto i taua wā, neke atu i te 50 miriona ngā tūranga poraka taunga kua tukuna e mātou ki ngā kiritaki i roto i te neke atu i te 40 whenua. I whakawhanakehia tā mātou raina hua taumaha hei whakautu i te wheako rahunga mara i Michigan i te tau 2012 — ā, ko ia whakatau hoahoa o ā mātou hua o nāianei e hoki ana ki ngā āhuatanga whakahaere MCC o te ao tūturu, ehara i te mea ko ngā whakatakotoranga whakamātautau taiwhanga anake.
Ko tā mātou āheinga hanga poraka taunga taumaha ko:
- Ngā whakatauranga o nāianei: 80A, 100A, 125A, 150A, 175A, 200A, 250A, 300A, me te 400A
- Ngā awhe waea: 6mm² ki te 150mm² (AWG 10 ki te 300 kcmil)
- Ngā momo hononga: Pūmau/poro (M5-M12), rawhi tīwiri hiko, rawhi pouaka/rawhi nohoanga
- Ngā Tiwhikete: Kua whakarārangihia ki te UL 1059, kua tohua ki te tohu CE, e tutuki ana i te RoHS/REACH, ISO 9001:2008 QMS
- Ngā whakatauranga SCCR: 10kA ki te 65kA me ngā ripanga taputapu tiaki kua whakaritea
- Ngā rauemi whare: PA66 GF30, UL94 V-0, CTI >400V
- Ngā āheinga ritenga: Waitohu OEM, tae ritenga, whirihoranga whakatauranga whakaranu, tohu motuhake
Ka whakamatautauria ia poraka pito taumaha e tukuna ana e mātou ki te 100% hiko — te ātete hiko i te 2× ngaohiko whakatauranga + 1000V, te ine ātete pa ki ia tūranga pito, me te tirotiro tirohanga i raro i te whakanui 10×. Ehara tēnei i te paerewa ahumahi; ko tā mātou paerewa tēnei. I tangohia e mātou tēnei paerewa nā te mea ko te utu mō te rahunga i te mara - arā, te ingoa pai, te whakawhirinaki a te kiritaki, me te moni tūturu - he nui ake i te utu o te whakamātautau.
