I-GBT 18487.1-2015 ichaza igama elithi umvikeli wamanje oyinsalela ngale ndlela: Isivikeli samanje esiyinsalela (RCD) isitsha sokushintshwa esisebenza ngomshini noma inhlanganisela yezinto zikagesi ezingavula, zithwale futhi ziphule imanje ngaphansi kwezimo ezijwayelekile zokusebenza, kanye nokunqamula abathintwayo uma insalela yamanje ifinyelela inani elishiwo.Igiya lokushintshwa elingumshini noma inhlanganisela yezinto zikagesi ezingakhanyisa, zithwale futhi zinqamuke ngaphansi kwezimo ezivamile zokusebenza futhi ezinganqamula abathintwayo lapho amandla asalayo afinyelela inani elishiwo ngaphansi kwezimo ezithile.
Izinhlobo ezihlukene zesivikeli samanje esisele ziyatholakala ezimeni ezihlukene zokuvikela futhi uhlobo olufanele lokuvikela kwamanje okusele kufanele lukhethwe ukuze lesi simo sivikelwe.
Ngokwesigaba esijwayelekile sensalela yamanje equkethe izici zesenzo sengxenye ye-DC, abavikeli bamanje abayinsalela bahlukaniswa kakhulu ngabavikeli bamanje abayinsalela yohlobo lwe-AC, uhlobo lwezivikeli zamanje eziyinsalela yohlobo, uhlobo luka-F lwezivikeli zamanje eziyinsalela kanye nohlobo luka-B lwezivikeli zamanje eziyinsalela.Imisebenzi yabo ngokulandelana kwayo imi kanje.
Uhlobo lwe-AC lwesivikeli samanje esisele: i-sinusoidal AC residual current.
Uhlobo A lwesivikelo samanje esisele: Umsebenzi wohlobo lwe-AC, wamanje ophehla insalela ye-DC, wamanje ophehlayo wensalela ye-DC obekwe phezulu ku-6mA we-DC yamanje ebushelelezi.
Umvikeli wamanje oyinsalela wohlobo F: Uhlobo A, ingxubevange yamanje eyinsalela evela kumasekhethi anikwe amandla yisigaba nokungathathi hlangothi noma amakhondaktha wesigaba nomhlaba amaphakathi, amandla amanje aphehlayo ensalela ye-DC abekwe phezulu ku-DC ebushelelezi engu-10mA.
Isivikeli samanje sensalela yohlobo B: Uhlobo F, i-sinusoidal AC eyinsalela yamanje ku-1000Hz nangaphansi, insalela yamanje ye-AC ibekwe ngaphezulu izikhathi ezingu-0.4 zesenzo sensalela esilinganiselwe samanje noma esingu-10mA esibushelelezi se-DC samanje (noma yikuphi okukhulu), ukunyakazisa insalela yamanje ye-DC ibekwe ngaphezulu izikhathi ezingu-0.4 izikhathi ezingu-0.4 ilinganiselwe isenzo sensalela yamanje noma i-10mA ebushelelezi ye-DC yamanje (noma yikuphi okukhulu), insalela yamanje ye-DC evela kumasekhethi alungisiwe, i-DC eyinsalela yamanje.
Isakhiwo esiyisisekelo seshaja esebhodini ye-EV ngokuvamile sihlanganisa ukuhlunga kwe-EMI kwesigaba sokufaka, ukulungisa kanye ne-PFC, umjikelezo wokuguqulwa kwamandla, isihlungi se-EMI sesigaba sokuphumayo, njll. Ibhokisi elibomvu esithombeni esingezansi libonisa isici samandla esinezigaba ezimbili. isifunda sokulungisa esinesiguquli sokuhlukanisa, lapho i-Lg1, i-lg2 nama-capacitor asizayo enza isihlungi se-EMI sokufaka, i-L1, C1, D1, C3, Q5 yakha uhlobo lokukhuphuka Isekhethi ye-PFC yesiteji sangaphambili, Q1, Q2, Q3, Q4, T1 , i-D2, i-D3, i-D4, i-D5 yakha umjikelezo wokuguqulwa kwamandla wesiteji esingemuva, i-Lg3, i-lg4 nama-capacitor asizayo enza isihlungi se-EMI esiphumayo ukuze kuncishiswe inani le-ripple.
Phakathi nokusetshenziswa kwemoto, nakanjani kuzoba namaqhubu nokudlidliza, ukuguga kwedivayisi nezinye izinkinga ezingenza ukuvala ngaphakathi kweshaja yemoto kube yinkinga, ukuze ishaja yemoto enqubweni yokushaja i-AC ezindaweni ezahlukene zokuhlaziya imodi yokwehluleka. ingatholakala ngendlela elandelayo izindlela zokuhluleka.
(1) iphutha eliphansi ohlangothini lwe-AC lokokufaka kwenethiwekhi kamasipala, ngaleso sikhathi iphutha lamanje kuba imvamisa yemboni ye-AC yamanje.
(2) Iphutha eliphansi esigabeni sokulungisa, lapho iphutha lamanje lishaya i-DC current.
(3) Iphutha le-DC/DC eliphansi nhlangothi zombili, lapho iphutha lamanje libushelelezi le-DC yamanje.
(4) Iphutha le-transformer lomhlabathi lokuhlukaniswa, iphutha lamanje alikho imvamisa ye-AC yamanje.
Kusuka ohlotsheni oluyinsalela lwamanje lokuvikela isivikelo umsebenzi akwaziwa, ingavikela uhlobo AC umsebenzi, pulsating DC residual current, pulsating DC residual current superimposed under 6mA smooth DC current, kanye neshaja yemoto DC fault current ≥ 6mA, A uhlobo. umvikeli wamanje osele angase abonakale e-hysteresis noma angeke enze, okuholela emsebenzini ojwayelekile, khona-ke umvikeli wamanje osele uzolahlekelwa umsebenzi wokuvikela.
I-European standard IEC 61851 ayigunyazi Uhlobo B, kodwa kuma-EVSE anezivikeli zamanje ezisele zohlobo A, kuyadingeka ukuqinisekisa ukuthi isekethe yephutha enokuqukethwe kwe-DC okungaphezu kuka-6mA iyanqanyulwa, eyodwa noma enye.Kuhlanganiswe nokuhlaziywa kokukhethwa komvikeli wamanje okuyinsalela engenhla, kuyacaca ukuthi uma ukuvikelwa kwephutha okungenhla kufanele kuhlangatshezwane nakho, ngokombono wezokuphepha, kudingeka uhlobo lwe-B lwesivikeli samanje oluyinsalela.
