- Ka pā tika te whiriwhiri i te kaihanga tika ki te pono o te pūnahaMā ngā poraka ārai kua whakamanahia e te UL 1059 me te IEC 60947-7-1 mai i tētahi kaiwhakarato mātau ka whakarite kia pumau te kaha hiko-kore, kia ātete-mura ngā rauemi, kia pumau hoki te pāmahana mō te wā roa i raro i te kawenga tonu.
- Kei a J-GUANG ngā poraka arai momo-tīwiri me te pana-roto me ngā whare PA66 e tutuki ana i ngā whakaritenga UL, kua whakatauria mō te 10 A ki te 400 A, kua whakamauhia ki runga i ngā rēra DIN TS 35 paerewa mō ngā tono tohatoha mana modular.
Mena kei te rapu koe i tētahi kaihanga poraka taunga ārai mō te tohatoha hiko ngaohiko-tiketike me te whakairinga reera DIN, anei te whakautu tika: Me tuku e te kaihanga tika ngā poraka pito kua whai mana UL 1059, IEC 60947-7-1 rānei ki te kaha hiko kua whakamanahia, ngā arai wehewehe ā-tinana i waenga i ia pou, me te whakamau rēra DIN kore-taputapu ki runga i ngā rēra paerewa TS 35. Nā te mea ko te mahi matua o te poraka tauārai he ārai i te āwhata i waenga i ngā ara iahiko ngaohiko teitei e tata ana., ko te kounga o te rauemi whakamarumaru — ko te nuinga he UL 94 V-0 te whakatauranga PA66, PBT rānei — me te tika o te whakakikorua pakitara ārai e whakatau tika ana i te pono mō te wā roa o ngā panera tohatoha hiko. I J-GUANG, ko ia poraka mutunga ārai e hangaia ana e mātou ka whakamatautauria te ātete hiko i te 2500 V AC mō te 60 hēkona e ai ki ngā whakaritenga UL 1059 i mua i te tukunga.
Ka ārahi tēnei aratohu i ngā kaihanga hokohoko, ngā kaihanga panera, me ngā kaituku hiko i roto i ngā paearu whiriwhiri nui i te wā e aromatawai ana i tētahi kaihanga poraka taunga arai: ngā mātāpono wehewehe ngaohiko, ngā paerewa whakairinga reera DIN, ngā whakatakotoranga rauemi, ngā whakaritenga tiwhikete, me ngā whakaaro tono o te ao tūturu. Ka tohaina e au aku mea i ako mai i te tuku poraka pito ki te neke atu i te 200 ngā kiritaki ahumahi puta noa i te 30 whenua.
He aha te Poraka Whakamutunga Ārai, ā, he aha te Hiranga o te Wehewehenga?
He hononga hiko whakamahana te poraka taunga ārai e whakamahi ana i ngā pakitara ā-tinana kua whakaarahia — ngā ārai — i waenganui i ia tūranga taunga. hei waihanga i ngā tawhiti ngoki me te tawhiti whakawātea e ārai ana i te āwhata hiko me ngā ara iahiko poto tūpono. He rerekē ki ngā poraka pito whāngai paerewa e noho ana ngā ara iahiko tata ki roto i ngā kōhao tuwhera, ka wehea e ngā poraka ārai ia pūwāhi hononga ki tētahi pakitara pakari o te kirihou hangarau ātete-mura.
He mea nui tēnei wehewehenga nā te mea ka hangaia e ngā ara iahiko tohatoha hiko ngaohiko-tiketike — te nuinga o te wā mai i te 380 V ki te 690 V AC i ngā taiao ahumahi — ngā āhuatanga ka taea e te poke o te mata, te hauhautanga, te wiri rānei te whakaputa i te mura i waenga i ngā pito kāore i te whakamahanatia. Kua tirotirohia e au tētahi pakaru o te mara i tētahi teihana papu i Texas, i reira ka taea e tētahi poraka pito kore-ārai te whai i te waro i waenga i ngā āhua tata i te 480 V AC, ka puta he poto āhua-ki-āhua i hinga ai te pokapū whakahaere motuka katoa. Nā taua aituā anake i pau te whare tata ki te USD 47,000 i roto i te wā whakatā kore i whakaritea. Mēnā he poraka pito aukati kua tohua tika, kua āraia ā-tinana taua ara whai.
Mō te UL 1059 paerewa, ka whakarōpūtia ngā poraka pito mā te whakatauranga ngaohiko i runga i te tawhiti ngoki me te tawhiti whakawātea. Mō te poraka ārai 600 V te whakatauranga, me 6.4 mm (0.252 inihi) te iti rawa o te tawhiti ngoki i waenga i ngā wāhanga ora kāore i te whakamahanatia. Ko te IEC 60947-7-1 E tautuhia ana e te paerewa he anga ōrite mō ngā poraka 1000 V AC / 1500 V DC kua whakatauria me ngā whakaaro mō te taumata parahanga 3.
⚡ Pānga o te Ao Tūturu
Nā te mea ka āraia e ngā pakitara ārai te whai i te pewa i waenga i ngā pito tata, mā te huri mai i te poraka whāngai-roto ki te poraka ārai kua whakatauria tika, ka whakaitihia te tere o te aituā ara iahiko poto mā te neke atu i te 90% i roto i te tipu tukatuka kai i mahi tahi mātou i te tau 2024. Nā ngā ārai i whakakore te aratau rahunga tuatahi — te puehu waro e hono ana i waenga i ngā kaiārahi hiko i roto i te taiao horoi.
Ngā Whakatakotoranga Matua i te Wā e Kōwhiria ana he Kaihanga Poraka Whakamutunga Ārai
1. Te Whakatauranga Ngaohiko me te Kaha Whakakorehiko
He ngaohiko whakahaere whakatauranga kei ia poraka tauārai e tautuhi ana i tōna ngaohiko mahi haumaru mōrahi. Ko te whakatauranga e whakawhirinaki ana ki te tawhiti i waenga i ngā ārai, te taupū aroturuki whakatairite (CTI) o te rauemi whakamarumaru, me te nui o te parahanga o te taiao e whakaarohia ana. E toru ngā akomanga ngaohiko e tautuhia ana e te UL 1059: 300 V, 600 V, me te 1000 V. Ka whakawhānuihia tēnei e te IEC 60947-7-1 ki te 1000 V AC me te 1500 V DC.
Ko te whakamātautau ātete dielectric te tohu a te kaihanga mō te kaha wehe. E ai ki te UL 1059, me tu te poraka ārai 600 V i te 2500 V AC e whakamahia ana mō te 60 hēkona me te kore e pakaru, e nui rawa rānei te ia turuturu. Ka tūtohu tonu ahau kia pātai atu ki tō tākuta kaihanga poraka taunga arai mō te pūrongo whakamātautau tuturu — kaua ko te tiwhikete anake — nā te mea e whakaatu ana te pūrongo i ngā uara o te iahiko turuturu i inehia. Me whakaatu e te poraka pai te turuturu i raro i te 1 mA i te 2500 V.
2. Te Kaha o nāianei me te Awhe o te Arataki
Ko ngā whakatauranga o nāianei mō ngā poraka pūrua arai kei waenga i te 10 A mō ngā ara iahiko whakahaere tae atu ki te 400 A mō ngā whāngai mana matua. Ko te wāhanga whakawhiti o te ara iahiko te mea e whakatau ana i te kaha o te iahiko: ko te pūrua 2.5 mm² (AWG 14) ka taea te whakatauranga mō te 24 A, ko te pūrua 35 mm² (AWG 2) ka taea te whakahaere tae atu ki te 150 A. Ko te tawhā matua i konei ko te pikinga pāmahana — ka whakawhāitihia e te UL 1059 te pikinga pāmahana i te pūrua ki te 30 °C i runga ake i te taiao i raro i te iahiko whakatauranga.
Ka tūtohu ahau kia whakaitihia tonutia te whakatauranga o nāianei kua whakaputaina e te kaihanga mā te 20% pea. mō ngā tono mahi tonu i roto i ngā kāpata kua katihia ina neke atu te pāmahana taiao i te 40 °C. He ture matua tēnei i whakawhanakehia e au i muri i te kitenga i ngā pāmahana o roto o te kāpata e eke ana ki te 55 °C i roto i tētahi tipu hurihuri rā o Mareia — i mahi tonu ā mātou poraka whakamutunga i roto i ngā whakaritenga e toru tau i muri mai nā te mea kua tohua e mātou te rahi e whai ake nei i te whakatauranga ingoa.
3. Rauemi Ārai me te Whare Noho
Ko te rauemi o te whare o te poraka ārai te mea tino nui e rerekē ai te kounga i waenga i ngā kaihanga. Ko te paerewa ahumahi ko te PA66 (nylon 66) me te PBT (polybutylene terephthalate) kua whakapakarihia ki te muka karāhe, e rua ngā mea kua whakatauria kia UL 94 V-0 mō te ātete mura. He pai ake te kaha miihini o te PA66 me te pāmahana ratonga tonu teitei ake (tae atu ki te 120 °C), ko te PBT ia e whakarato ana i te pumau o ngā āhuatanga me te iti o te mimiti makuku.
Kāore e rite ana ngā PA66 katoa. I roto i tā mātou wheketere i Ningbo, ka tangohia e mātou te PA66+GF30 kounga-kore (30% muka karāhe) mai i ngā kaiwhakarato whai mana, ā, ka whakahaerehia he whakamātautau rauemi DSC (Differential Scanning Calorimetry) hei manatoko i te ira rewa me te pāmahana whakawhiti karāhe. Kua kite ahau i te pakaru o ngā poraka pito iti ake te utu i roto i ngā marama e ono nā te mea i whakamahia e te kaihanga te PA66 hangarua me te tohatoha muka koretake - ka pakaru ngā arai i raro i te huringa wera, ā, ka heke te CTI i raro i te whakatakotoranga iti rawa.

Ae, he maha ngā poraka taunga arai hou kua hangaia mō te whakairi tika i te rēra DIN ki runga i ngā rēra paerewa TS 35 (35 mm) e ai ki te DIN EN 60715. Mā te whakairinga rēra DIN ka taea te tāutanga ā-pūrua, ka whakaiti i te wā huihuinga kāpata, ā, ka māmā ake te tiaki me te whakahou ā muri ake nei. Ko ētahi poraka arai e whakamahi ana i ngā turanga whakapiri-whakauru kua whakauruhia, ko ētahi e hiahia ana ki te turanga urutau. I J-GUANG, ka hoahoa mātou i ā mātou poraka taunga arai hototahi ki te rēra DIN me ngā tikanga whakapiri-whakauru kore-taputapu e mau tonu ana ki te rēra ka tukuna mā te whakamahi i te tīwiri ngāwari.
He aha ngā tiwhikete e tika ana kia whiwhihia e te kaihanga poraka tauārai pono?
Me pupuri e te kaihanga poraka taunga ārai pono te tohu UL 1059 (paerewa mō ngā poraka taunga i Amerika Te Raki), te IEC 60947-7-1 (paerewa ā-ao mō ngā poraka taunga), te tohu CE mō te urunga ki te mākete Pākehā, me te RoHS mō te haumaru taiao. Tērā pea ka hiahiatia ētahi atu tohu pēnei i te CSA, TUV, ATEX rānei, i runga i te tono me te ahumahi e hiahiatia ana. Mā ēnei tohu ka whakaū kua paahitia e ngā hua a te kaihanga ngā whakamātautau motuhake a te hunga tuatoru mō te haumaru hiko, te roa o te mahi miihini, me te mahi wera i raro i ngā tikanga whakamātautau kua tautuhia.
Me pēhea taku whiriwhiri i waenga i ngā poraka arai momo-tīwiri me ngā poraka arai pana-roto?
Ko te kōwhiringa i waenga i ngā poraka arai momo-tīwiri me te arai pana-whakauru ka whakawhirinaki ki te taumata wiri o tō tono, te auau tiaki, me ngā whakaritenga whakawhiti waea. He nui ake te kaha o te kume a ngā poraka arai momo-tīwiri, ā, he pai ake mō ngā taiao wiri nui me ngā rahi arataki nui ake (neke atu i te 10 AWG / 6 mm²). He rerekē, ka whakaitihia e ngā poraka arai pana-whakauru te wā waea tae atu ki te 60% nā te mea kāore e hiahiatia he whakakī tīwiri, ā, ka whakaaetia ngā waea totoka, ngā waea kua mutu ki te ferrule me te nekehanga whakauru ngāwari. Mō ngā tono tohatoha mana me ngā rahi arataki whakauru, ka tūtohu a J-GUANG i ngā poraka arai momo-tīwiri mō te whāngai mana matua me ngā poraka pana-whakauru mō ngā ara iahiko peka kei reira te wāhi me te tere e whai tikanga ana.
He aha te rerekētanga i waenga i te poraka taunga ārai me te poraka taunga whāngai?
Ko te rerekētanga matua ko te whakaurunga o ngā pakitara whakamahana teitei i waenganui i ia tūranga o te pūrua ki te wehe ā-tinana i ngā hononga tata, engari ko te pūrua whāngai-mā roto he maha ngā kōhao pūrua kua whakatōkia, kāore he ārai e wehe ana. Ka whakaratohia e ngā poraka ārai he parenga pai ake i te arai āwhata me ngā ara iahiko poto, ā, koinei te whiringa pai mō te tohatoha hiko ngaohiko-tiketike i runga ake i te 250 V. He iti ake te kiato o ngā poraka whāngai-mā roto, ā, he iti ake te utu mō ngā waea tohu ngaohiko-iti me ngā ara iahiko whakahaere. I roto i te mahi hoahoa papaaho, ka whakamahia e mātou ngā poraka ārai mō ngā hiko matua AC me ngā ara iahiko motuka i te wā e whakamahia ana ngā poraka whāngai-mā roto mō ngā hononga PLC me ngā pūoko.
He aha ngā rahi o ngā arai hiko ka taea te whakauru ki ngā poraka taura ārai?
He whānuitia ngā rahi o ngā arai hiko e taea ana te whakamahi i ngā poraka pito arai, i runga i te raupapa. Ko ngā whānuitanga noa mai i te 0.2 mm² (AWG 24) mō ngā waea whakahaere tae atu ki te 300 mm² (600 kcmil) mō te tohatoha mana taumaha. Ko ngā poraka arai tohatoha mana tino noa ka taea te whakamahi i te 2.5 mm² ki te 16 mm² (AWG 14 ki te AWG 6). Ka tohua e ia tauira poraka arai he wāhanga whakawhiti arai iti rawa me te mōrahi me te taipana whakakī e taunakitia ana mō ngā pito tīwiri. Mā te neke atu i te whānuitanga waea kua whakatauria ka pāngia te ātete pa me te pono mō te wā roa.
Me pēhea taku manatoko i te kounga o tētahi kaihanga poraka taunga ārai?
Hei manatoko i te kounga o te kaihanga poraka pito ārai, tonoa ngā pūrongo whakamātautau a te hunga tuatoru mō te kaha hiko-kore (te tikanga 2500 V AC mō te 1 meneti ia UL 1059), te pikinga pāmahana i te iahiko kua whakatauria, me te manawanui miihini (te maha o ngā huringa whakauru/tango). Pātaihia ngā tiwhikete rauemi — ko te rauemi whare PA66, PBT rānei kua whakatauria e te UL 94 V-0 e tohu ana i te ātete mura pai ake. Haere ki te wheketere, tono rānei i tētahi haerenga ataata hei tirotiro i te tika o te hanga me te kounga huihuinga. Tirohia ngā tauira mō te matotoru ōrite o te pakitara ārai, ngā mata pito kore-pūwero, me te hononga miro tīwiri ōrite. Me whakarato katoa ēnei e te kaihanga rongonui me te kore e whakaroa.
