Ungasarudza sei circuit breaker yakakodzera yeEV Chargers?

Ungasarudza sei circuit breaker yakakodzera yeEV Chargers?

Senyanzvi yezvekuchaja zvivakwa zvemagetsi, CHINAEVSE inofara kukutungamira munzira yekusarudza nekuisa circuit breaker yekuisa Electric Vehicle Supply Equipment (EVSE).

Kuisa circuit breaker chaiyo ndeimwe yematanho akakosha pakugadzira chiteshi chekuchaja cheEV. Nekuti kuchaja kweEV kunoonekwa semutoro unoenderera mberi(ichitora simba remagetsi rakawanda kwemaawa panguva imwe chete), mitemo yemagetsi yemudzimba kana yekutengeserana inofanira kushandiswa zvakasimba kudzivirira kupisa zvakanyanya, kukanganiswa, kana njodzi dzemoto.

Heino gwara rakazara pamusoro pezvinhu zvine chekuita nehunyanzvi, mitemo yekuchengetedza, uye nzira dzakanakisisa dzekuisa EVSE circuit breaker.

1. Mutemo we125% (Kuverenga Mutoro Unoramba Uchienderera Mberi)

Kusiyana nemidziyo yemumba inomhanya nguva nenguva (senge microwave kana toaster),Chaja yemagetsiinoshanda nesimba rakawanda kwenguva yakareba.

• Mutemo:Pasi peNational Electrical Code (NEC) neIEC equivalents, munofanira kuisa saizi yecircuit breaker nemaconductor pa125% yemagetsi anobuda nguva dzose mucharger yeEV.
• Masvomhu:Kana bhokisi rako remagetsi remagetsi rikabuda32A, kuverenga kwehukuru hwemuputsi ndekwekuti:

Saka, unofanira kuisa40A circuit breaker.

Tafura Yekutarisa Yekuputsa Yakajairika

2. Kusarudza Rudzi Rwakakodzera rweBreaker

Zvichienderana nezvinodiwa munharaunda yenyu (North American NEC vs. International/European IEC), zvinodiwa pamhando dzedziviriro zvinosiyana.

A. Dziviriro yeMagetsi Akasara & Kukanganisa Kwepasi (RCD / GFCI)

Kuchaja magetsi emagetsi (EV charging) kune njodzi dzakasiyana-siyana maererano nekubuda kwemagetsi emagetsi emagetsi eDC, izvo zvinogona "kudzima" michina yakajairika yerudzi rweA.

• Misika yeIEC (Europe/Australia/Asia):Kana EVSE isina 6mA DC leakage detection, iwezvinofanirashandisaRCD yerudzi rweBkana RCBO (Residual Current Breaker ine Overcurrent protection) iyo inoona zvikanganiso zveAC neDC. Kana EVSEanoitaine 6mA DC detection yakabatanidzwa, standardRudzi A RCDkazhinji zvakakwana.
• Misika yeNEC (North America):MaEVSE mazhinji emazuva ano eLevel 2 ane dziviriro yeCCID50 (Personnel Protection) yakavakirwa mukati. Zvisinei, kana uri kuisachibatanidziroEVSE (semuenzaniso, NEMA 14-50 kana 6-50 yekubuda), NEC 2020/2023 inodaGFCI breakermupanera rechinhu ichocho, kunyangwe kana charger iine dziviriro yayo yemukati.

B. Makomba erwendo rweCircuit Breaker (IEC)

Kana uchishanda pasi pemitemo yeIEC, kusarudza trip curve chaiyo kunodzivirira matambudziko kubva pamagetsi ekutanga ekupinda kana EV yatanga kuchaja:

• Rudzi C Curve:Inokurudzirwa zvikuru pakuisa EVSE. Inobata mafungu emhepo ari pakati nepakati asingagumburwe nguva isati yakwana.
• Dzivisa makomba erudzi rweB kunze kwekunge zvataurwa nemakodhi emunharaunda, sezvo anogona kugumburwa zviri nyore kana zvinhu zvakawanda zvichiramba zvichirema.

3. Zvaunofanira Kufunga Nezvekuisa Zvinhu Zvakakosha

Kukura kweWaya uye Kudzikisa Kupisa

Chinopwanya chinoshanda zvakanaka chete sewaya yakabatana nayo. Nekuda kwemutoro unoramba uchienderera mberi, iva nechokwadi chekuti waya (AWG kana mm2) inoenderana nehukuru hwechinopwanya.mushure mezvichireva kubviswa kwekupisa kana waya dzichipfuura nenzvimbo dzinopisa (senge denga) kana nzira dzinoshandiswa nevanhu.

• Muenzaniso:Kune breaker ye50A,Waya yemhangura ye6 AWGndizvo zvakajairika. Usambofa wakakanganisa breaker ine maamp akawanda ine waya dzisina kukura.

Magadzirirwo eTorque

Kubatana kusina kusimba ndicho chikonzero chikuru chekubvira kwemoto wemagetsi muma EV setups. Kana mota dzichiramba dzichitakura, ma terminal asina kusimba anogadzira kuramba kwakanyanya, zvichikonzera kuungana kwekupisa kwakanyanya kunogona kunyungudutsa breaker ne panel busbar.

• Shandisa sikurudhiraivha/chipanera chetorque chakagadziriswa nguva dzosekusimbisa machira emuchina wekupwanya zvinhu kuti zvienderane nezvinodiwa nemugadziri (zvinowanzo dhindwa padivi pemuchina wekupwanya zvinhu).

Kugona kwePaneli & Kupisa Kwemhepo

• Kuverenga Mutoro:Usati wawedzera 40A kana 60A breaker, ita kuverenga mutoro pane panel/property iripo kuti uve nechokwadi chekuti sevhisi huru inogona kubata mutoro wekuwedzera unoenderera mberi.
• Kupisa Kunopisa:Kana ukaisa maEV breaker akawanda padivi nepadivi mubhodhi rekutengesa, funga nezvekusiya nzvimbo isina chinhu pakati pawo kuti mhepo ifambe zvakanaka uye kupisa kupararire.

4. Rondedzero yekutarisa yekuisa kwehunyanzvi

1. Mvumo & Mitemo:Gara uchitarisa kuti mitemo yemuno inotevedzwa sei (semuenzaniso, NEC Article 625, IEC 60364-7-722) wobva watora mvumo dzemagetsi dzinodiwa.
2. Hardware vs. Plug-in:Kuisa tambo dzemagetsi kunofarirwa zvikuru nekuda kwekuvimbika kwakanyanya uye hakudi kuti pave nechinhu chinodhura chekunze cheGFCI breaker munzvimbo dzakawanda.
3. Kunyora mazita:Nyora zita rakajeka pachinhu chinopwanya chiri mupaneru huru sekuti “EV CHARGER” kuti uve nechokwadi chekuti chinoonekwa nekukurumidza panguva yekugadzirisa.
4. Kuedzwa Mushure mekuiswa:ShandisaEVSEkuyedza adapta yekutevedzera kubatana kwemotokari uye kuyedza mashandiro eRCD/GFCI trip usati waipa kumushandisi wekupedzisira.
