GBT 18487 ikigezweho gisigaye kigera ku giciro cyagenwe.Nibikoresho bya mashini cyangwa guhuza ibikoresho byamashanyarazi bishobora gufungura, gutwara no kumena amashanyarazi mugihe gisanzwe gikora kandi gishobora guhagarika imikoranire mugihe amashanyarazi asigaye ageze kubiciro byagenwe mubihe byagenwe.
Ubwoko butandukanye bwibisigisigi birinda birahari kubintu bitandukanye byo kurinda kandi ubwoko bukwiye bwo kurinda ibisigisigi bigomba guhitamo kugirango ibintu bikingirwe.
Ukurikije ibyiciro bisanzwe byerekana ibisigisigi birimo ibintu bya DC biranga ibikorwa, abashinzwe kurinda ibisigara bigabanijwe cyane cyane mubice bya AC bisigara birinda ibyuma birinda ibintu, Ubwoko bwimyanda isigara, ubwoko bwa F busigaye burinda ibintu hamwe nubwoko bwa B busigaye burinda ibintu.Inshingano zabo ni izi zikurikira.
Ubwoko bwa AC busigaye burinda ibintu: sinusoidal AC isigaye.
Ubwoko bwa A busigaye burinda ibintu: imikorere yubwoko bwa AC, guhinduranya DC ibisigisigi bya DC, gusohora DC ibisigisigi bya DC hejuru ya 6mA yumuyaga wa DC woroshye.
Ubwoko bwa F busigaye burinda ibintu: Ubwoko A, imiyoboro isigara ivuye mumuzunguruko ikoreshwa nicyiciro kandi kidafite aho kibogamiye cyangwa icyiciro hamwe nubutaka buringaniye bwisi, impiswi ya DC isigara hejuru yumuriro wa DC ya 10mA.
Ubwoko B busigaye burinda ibintu: Ubwoko F, sinusoidal AC isigara kuri 1000Hz no munsi yayo, amashanyarazi asigaye ya AC yarengeje inshuro 0.4 igipimo cyibisigisigi cyagenwe cyangwa 10mA yoroshye ya DC (niyo yaba ari nini), ihinduranya DC isigara hejuru yikubye inshuro 0.4 inshuro igipimo cyibisigisigi cyibikorwa cyangwa 10mA yoroshye ya DC (niyo iruta iyindi), DC isigara iva mumuzunguruko ikosowe, amashanyarazi asigaye ya DC.
Ubwubatsi bwibanze bwa EV kuri charger muri rusange burimo EMI kuyungurura igice cyinjiza, gukosora na PFC, guhinduranya amashanyarazi, EMI muyunguruzi kubisohoka igice, nibindi. Agasanduku gatukura mumashusho hepfo yerekana ibintu bibiri byingufu Inzira yo gukosora hamwe na transformateur yo kwigunga, aho Lg1, lg2 na capacator zifasha gukora kwinjiza EMI muyunguruzi, L1, C1, D1, C3, Q5 bigize intambwe yo gutera intambwe Ubwoko bwa mbere PFC umuzenguruko, Q1, Q2, Q3, Q4, T1 .
Mugihe cyo gukoresha ikinyabiziga, byanze bikunze hazabaho gutitira no kunyeganyega, gusaza kwibikoresho nibindi bibazo bishobora gutuma insulasiyo mumashanyarazi yimodoka itera ikibazo, kuburyo kubushoferi bwimodoka mugikorwa cyo kwishyuza AC ahantu hatandukanye muburyo bwo gusesengura uburyo bwo kunanirwa irashobora kuboneka kuburyo bukurikira uburyo bwo gutsindwa.

(3) DC / DC ikosa ryubutaka kumpande zombi, mugihe ikosa ryoroshye ryoroshye DC.

Kuva mubwoko bwa A busigara burinda ibikorwa byo kurinda birashobora kumenyekana, birashobora kurinda imikorere yubwoko bwa AC, guhinduranya DC ibisigisigi bya DC, guhindagura DC ibisigisigi bya DC bitarenze munsi ya 6mA byoroshye DC, hamwe na charger yimodoka DC ikosa ≥ 6mA, Ubwoko ibisigisigi byubu birinda bishobora kugaragara hystereze cyangwa ntibikora, bikavamo akazi gasanzwe, noneho ibisigisigi byubu bisigaye bizabura imikorere yo kurinda.
Ibipimo ngenderwaho byu Burayi IEC 61851 ntibitegeka Ubwoko B, ariko kuri EVSEs hamwe nubwoko bwa A bwasigaye burinda ibintu, birakenewe ko hiyongeraho kwemeza ko umuzenguruko wamakosa ufite DC irimo ibintu birenga 6mA ucibwa, umwe cyangwa undi.Ufatanije nisesengura ryibisigisigi byavuzwe haruguru byatoranijwe kurinda, biragaragara ko niba uburinzi bwavuzwe haruguru bugomba kubahirizwa, uhereye kumutekano, hakenewe ubwoko bwa B busigaye burinda umutekano.
