Ungayikhetha kanjani i-circuit breaker efanele yama-EV Charger?

Ungayikhetha kanjani i-circuit breaker efanele yama-EV Charger?

Njengochwepheshe wengqalasizinda yokushaja i-EV, i-CHINAEVSE izokujabulela ukukuqondisa ngenqubo yokukhetha nokufaka i-circuit breaker yokufakwa kwe-Electric Vehicle Supply Equipment (EVSE).

Ukufaka i-circuit breaker efanele kungenye yezinyathelo ezibaluleke kakhulu ekusetheni isiteshi sokushaja se-EV. Ngoba ukushaja kwe-EV kubhekwa njengokushajaumthwalo oqhubekayo(idonsa ugesi ophezulu amahora amaningi ngesikhathi), imithetho ejwayelekile kagesi yezindlu noma yezentengiselwano kumele isetshenziswe ngokuqinile ukuvimbela ukushisa ngokweqile, ukukhubeka, noma izingozi zomlilo.

Nasi umhlahlandlela ophelele mayelana nokucabangela ubuchwepheshe, izindinganiso zokuphepha, kanye nemikhuba emihle kakhulu yokufaka i-EVSE circuit breaker.

1. Umthetho we-125% (Ukubalwa Komthwalo Okuqhubekayo)

Ngokungafani nezinto zasekhaya ezisebenza ngezikhathi ezithile (njenge-microwave noma i-toaster), i-Ishaja ye-EVisebenza ngamandla aphezulu isikhathi eside.

• Umthetho:Ngaphansi kwe-National Electrical Code (NEC) kanye ne-IEC equivalents, kufanele ulinganise i-circuit breaker kanye nama-conductor ku-125% womkhiqizo oqhubekayo ophezulu weshaja ye-EV.
• Izibalo:Uma ibhokisi lakho lodonga le-EV liphuma32A, ukubalwa kosayizi we-breaker yilokhu:

Ngakho-ke, kufanele ufake i-I-circuit breaker engu-40A.

Ithebula Lokubhekisela Lokulinganisa Usayizi Ovamile We-Breaker

2. Ukukhetha Uhlobo Olufanele Lokuphula

Kuye ngezindinganiso zakho zesifunda (i-North American NEC vs. International/European IEC), izidingo zezinhlobo zokuvikela zizohluka.

A. Ukuvikelwa Kwamanje Okusele kanye Nephutha Lomhlaba (RCD / GFCI)

Ukushaja i-EV kudala izingozi ezihlukile mayelana nokuvuza kwamanje kwephutha le-DC, okungaphazamisa amadivayisi ajwayelekile asele ohlobo A.

• Izimakethe ze-IEC (iYurophu/i-Australia/i-Asia):Uma i-EVSE ingenayo i-6mA DC yokuvuza eyakhelwe ngaphakathi, wenakumelesebenzisaUhlobo B lwe-RCDnoma i-RCBO (Residual Current Breaker enokuvikelwa kwe-Overcurrent) ethola amaphutha e-AC kanye ne-DC. Uma i-EVSEingabeine-6mA DC detection ehlanganisiwe, ejwayelekileUhlobo A lwe-RCDngokuvamile kwanele.
• Izimakethe ze-NEC (eNyakatho Melika):Ama-EVSE amaningi esimanje e-Level 2 ane-CCID50 (Personnel Protection) ground-fault protection eyakhelwe ngaphakathi. Kodwa-ke, uma ufaka i-i-plug-inI-EVSE (isb, i-NEMA 14-50 noma i-6-50 outlet), i-NEC 2020/2023 idingaI-GFCI breakerkuphaneli yaleso sitsha, noma ngabe ishaja inesivikelo sayo sangaphakathi.

B. Amajika Ohambo Lokuphula Isekethe (IEC)

Uma usebenza ngaphansi kwezindinganiso ze-IEC, ukukhetha ijika lohambo elifanele kuvimbela ukukhubeka okuvela kugesi wokuqala lapho i-EV iqala ukushaja:

• Ijika Lohlobo C:Kunconywa kakhulu ekufakweni kwe-EVSE. Iphatha amaza okungena aphakathi nendawo ngaphandle kokukhubeka ngaphambi kwesikhathi.
• Gwema amajika ohlobo B ngaphandle kokuthi kuchazwe amakhodi endawo, njengoba angakhubeka kalula kakhulu ngaphansi kwemithwalo ephezulu eqhubekayo.

3. Izinto Ezibalulekile Okufanele Uzicabangele Zokufaka

Usayizi Wezintambo Nokususwa Kokushisa

I-breaker ilingana kuphela nentambo exhunywe kuyo. Ngenxa yomthwalo oqhubekayo, qiniseka ukuthi i-wire gauge (AWG noma mm2) ihambisana nosayizi we-breaker.ngemvaokubangela ukuqhekeka kokushisa uma izintambo zidlula ezindaweni ezishisayo (njenge-attics) noma imigudu yokwabelana.

• Isibonelo:Ngomshini wokuvula i-50A,Ucingo lwethusi oluyi-6 AWGkuyinto ejwayelekile. Ungalokothi uphazamise i-high-amp breaker enezintambo ezincane.

Imininingwane yeTorque

Ukuxhumeka okuxekethile kuyimbangela yokuqala yomlilo kagesi kumasethingi e-EV. Ngaphansi komthwalo oqhubekayo, amatheminali axekethile adala ukumelana okuphezulu, okuholela ekukhuleni kokushisa okukhulu okungancibilikisa i-breaker kanye ne-panel busbar.

• Sebenzisa njalo isikulufu/isikrufu se-torque esilinganisiweukuqinisa ama-breaker lugs ngokwencazelo eqondile yomenzi (ngokuvamile anyatheliswa ohlangothini lwe-breaker).

Umthamo Wephaneli Nokushisa Okuzungezile

• Ukubalwa Komthwalo:Ngaphambi kokwengeza i-breaker engu-40A noma engu-60A, yenza ukubala umthwalo kuphaneli/impahla ekhona ukuqinisekisa ukuthi isevisi eyinhloko ingakwazi ukusingatha umthwalo owengeziwe oqhubekayo.
• Ukushabalalisa Ukushisa:Uma ufaka ama-EV breaker amaningi eceleni ebhodini lokusabalalisa lezentengiselwano, cabanga ngokushiya isikhala esingenalutho phakathi kwawo ukuze kuvunyelwe ukuhamba komoya okungcono kanye nokushabalaliswa kokushisa.

4. Uhlu Lokuhlola Lokufakwa Kobungcweti

1. Izimvume Nemithethonqubo:Hlola njalo ukuthobela imithetho yendawo (isib. Isigaba se-NEC 625, i-IEC 60364-7-722) bese udonsa izimvume zikagesi ezidingekayo.
2. I-Hardware vs. I-Plug-in:Ukufakwa kwezintambo eziqinile kukhethwa kakhulu ngenxa yokuthembeka okuphezulu futhi kuqeda isidingo se-breaker yangaphandle ye-GFCI ebizayo ezindaweni eziningi.
3. Ukulebula:Bhala ngokucacile i-breaker kuphaneli eyinhloko ngokuthi “I-EV CHARGER” ukuqinisekisa ukuhlonza okusheshayo ngesikhathi sokulungiswa.
4. Ukuhlolwa Kwangemva Kokufakwa:SebenzisaI-EVSEi-adaptha yokuhlola ukuze ilingise uxhumano lwemoto futhi ihlole ukusebenza kohambo lwe-RCD/GFCI ngaphambi kokuyidlulisela kumsebenzisi wokugcina.
