Ni gute wahitamo icyuma gitanga umuriro gikwiye kuri EV Chargers?

Ni gute wahitamo icyuma gitanga umuriro gikwiye kuri EV Chargers?

Nk'inzobere mu bijyanye no gusharija ibikoresho by'amashanyarazi, CHINAEVSE yishimiye kugufasha mu nzira yo guhitamo no gushyiramo icyuma gihagarika amashanyarazi (circuit breaker) kugira ngo gishyirweho ibikoresho by'amashanyarazi (EVSE).

Gushyiramo icyuma gitanga umuriro gikwiye ni imwe mu ntambwe z'ingenzi cyane mu gushyiraho sitasiyo yo gushyushya umuriro wa EV. Kubera ko gushyushya umuriro wa EV bifatwa nk'ikintuumutwaro uhoraho(gukurura umuyoboro w’amashanyarazi mwinshi amasaha menshi), amategeko asanzwe agenga amashanyarazi yo mu ngo cyangwa ay’ubucuruzi agomba gukurikizwa cyane kugira ngo hirindwe ubushyuhe bwinshi, gucika intege, cyangwa ibyago by’inkongi.

Dore ubuyobozi bwuzuye ku byerekeye tekiniki, amahame y'umutekano, n'uburyo bwiza bwo gushyiraho EVSE circuit breaker.

1. Itegeko rya 125% (Gusuzuma Umutwaro Uhoraho)

Bitandukanye n'ibikoresho byo mu rugo bikoresha igihe runaka (nk'icyuma gishyushya microwave cyangwa toaster),Shajara ya EVikora ku bushobozi ntarengwa mu gihe kirekire.

• Itegeko:Dukurikije Amategeko y'Igihugu agenga Amashanyarazi (NEC) n'ibigereranyo bya IEC, ugomba gupima icyuma gihagarika amashanyarazi n'ibiyobora amashanyarazi kuri125% by'umusaruro ntarengwa w'amashanyarazi uhoraho w'imodoka ya EV.
• Imibare:Niba amashanyarazi yawe asohoka ku rukuta32A, ingano y'umuvuduko w'imashini igabanya ibiciro ni iyi:

Kubwibyo, ugomba gushyirahoAkamashini gakoresha amashanyarazi ka 40A.

Imbonerahamwe y'Ubunini bw'Ibice Bisanzwe by'Ibice Bisanzwe

2. Guhitamo ubwoko bwiza bw'imashini igabanya ubukana

Bitewe n'amahame ngenderwaho y'akarere utuyemo (IEC y'Amerika y'Amajyaruguru ugereranyije n'IEC Mpuzamahanga/IEC y'i Burayi), ibisabwa ku bwoko bw'uburinzi biratandukanye.

A. Uburinzi bw'ibisigazwa by'umuriro n'uburinzi bw'ubutaka (RCD / GFCI)

Gushyushya amashanyarazi bitera ibyago bidasanzwe bijyanye no kuva kw'umuriro wa DC, bishobora "guhuma" ibikoresho bisanzwe bya Type A bisigaye.

• Amasoko ya IEC (Uburayi/Ositaraliya/Aziya):Niba EVSE idafite uburyo bwo gupima amazi ya DC ya 6mA, urashoboraugombakoreshaRCD yo mu bwoko bwa Bcyangwa RCBO (Residual Current Breaker ifite uburinzi bwa Overcurrent) isuzuma amakosa ya AC na DC. Iyo EVSEikoraifite uburyo bwo gupima DC bwa 6mA, busanzweUbwoko bwa A RCDubusanzwe birahagije.
• Amasoko ya NEC (Amerika ya Ruguru):EVSE nyinshi zigezweho zo ku rwego rwa 2 zifite uburinzi bw’ubutaka bwa CCID50 (Personnel Protection). Ariko, niba urimo gushyirahoplug-inEVSE (urugero, NEMA 14-50 cyangwa 6-50 isohoka), NEC 2020/2023 isaba aIgikoresho cyo gukata GFCImu gice cy'icyo gikoresho, nubwo icyuma gishyushya cyaba gifite uburinzi bwacyo imbere.

B. Imirongo y'urugendo rw'umuvuduko w'uruziga (IEC)

Niba ukorera ku bipimo ngenderwaho bya IEC, guhitamo umurongo ukwiye w'urugendo birinda ingorane ziterwa n'umuyoboro w'amashanyarazi winjira mu gihe amashanyarazi atangiye gusharija:

• Ubwoko bwa C:Irasabwa cyane mu gushyiraho EVSE. Ikora ku buryo buciriritse bwo kwinjira mu kirere kidatera igihombo.
• Irinde ko ubwoko bwa B buhinduka keretse iyo bugenwe n'amakode yo mu gace, kuko bushobora kugwa byoroshye cyane iyo imizigo myinshi idashira.

3. Ibitekerezo by'ingenzi ku bijyanye no gushyiraho

Ingano y'insinga n'ubushyuhe

Akamashini gakoresha amashanyarazi kaba gafite ubushobozi bwo gutandukanya insinga n'insinga. Kubera ko umutwaro uhoraho, menya neza ko insinga (AWG cyangwa mm2) ihuye n'ingano y'akamashini gakoresha amashanyarazi.nyumaKubara ingaruka z'ubushyuhe iyo insinga zinyuze mu bidukikije bishyushye (nk'ibyumba byo hejuru) cyangwa imiyoboro ihuriweho.

• Urugero:Ku gikoresho cyo gusohora 50A,Insinga 6 z'umuringa za AWGni ibisanzwe. Ntuzigere ubangamira igikoresho cyo gusohora amatara gifite amplifiers nyinshi gifite insinga ntoya.

Ibisobanuro by'ingufu

Imiyoboro idafite ingufu ni yo mpamvu ya mbere itera inkongi z'amashanyarazi mu byuma bikoresha amashanyarazi. Iyo umuriro ukomeje kwiyongera, imiyoboro idafite ingufu itera uburinzi bwinshi, bigatuma ubushyuhe bwinshi bushobora gushonga umuyoboro w'amashanyarazi n'umuyoboro w'amashanyarazi.

• Buri gihe koresha screwdriver/wrench ifite torque inganagufunga imigozi y'icyuma gicana umuriro ku buryo bukwiye bw'uwagikoze (ubusanzwe cyanditswe ku ruhande rw'icyuma gicana umuriro).

Ubushobozi bw'ibice by'imashini n'ubushyuhe bw'ikirere

• Kubara Imitwaro:Mbere yo kongeramo icyuma gihagarika 40A cyangwa 60A, banza ubaze umutwaro ku gice/umutungo uhari kugira ngo umenye neza ko serivisi nyamukuru ishobora kwihanganira umutwaro uhoraho wiyongereye.
• Gusesa ubushyuhe:Niba ushyizemo utumashini twinshi twa EV dufatanye mu kibaho cyo gukwirakwiza ibicuruzwa, tekereza gusiga umwanya udafite icyuho hagati yabyo kugira ngo umwuka unyure neza kandi ubushyuhe bugashira neza.

4. Urutonde rw'ibintu bigomba gukorwa mu buryo bw'umwuga

1. Impushya n'amabwiriza:Buri gihe genzura niba aho utuye hubahirizwa amategeko (urugero, ingingo ya NEC 625, IEC 60364-7-722) hanyuma ufate ibyangombwa by'amashanyarazi bikenewe.
2. Ifite insinga cyangwa porogaramu ikoreshwa mu gucomeka:Gushyiramo insinga zikozwe mu byuma bikundwa cyane kubera ko byizewe cyane kandi bigatuma bidasaba ko habaho imashini ihenze yo hanze ya GFCI mu turere twinshi.
3. Ibirango:Shyira ikimenyetso cy'imashini iri mu gice cy'ingenzi mu nyuguti "EV CHARGER" kugira ngo umenye neza ko ari yo ikoreshwa vuba mu gihe cyo kuyisana.
4. Isuzuma nyuma yo gushyirwaho:KoreshaEVSEgupima adaptateri kugira ngo yigane isano ry'imodoka no kugerageza imikorere ya RCD/GFCI mbere yo kuyiha umukoresha wa nyuma.
