Kurinda inzitizi zumuzingi, umutekano n'umutekano.

A kumena inzitizini ibikoresho byamashanyarazi bikunze gukoreshwa mumuzunguruko wa AC.Icyitegererezo cyingirakamaro muri rusange kigizwe nuwimuka wimuka, itumanaho ryimukanwa hamwe na static ihuza.Mu muzunguruko, moderi yingirakamaro irashobora guhagarika amashanyarazi, guhuza amashanyarazi no kurinda ibikoresho byamashanyarazi.Ukurikije imiterere n'ihame ry'akazi, birashobora kugabanywamoicyiciro kimwe cyumuzunguruko, ibyiciro bitatu byumuzunguruko kandikumena ikirere.Inzitizi zumuzingi, nkigikoresho cyo guhagarika hagati yumuzunguruko nogutanga amashanyarazi, bigira uruhare runini mumashanyarazi.Iyo imizigo irenze urugero, umuzunguruko mugufi nandi makosa, kurinda ibikorwa byamashanyarazi mugihe bizacibwa, kugirango umuzunguruko ufungure kurinda umutekano wumuntu numutungo nibindi bikoresho kwangirika.Nonehokumena inzitiziikoreshwa cyane muri sisitemu yingufu nayo yitwa "over-undervoltage protector" cyangwa "fuse".Imwe mumikorere yingenzi nuguhita uhagarika amashanyarazi mugihe hari uruziga rugufi.

Ihame ry'imikorere

Iyo umuyoboro wa AC unyuze kumurongo wamashanyarazi, gukurura amashanyarazi, gutwara ibikorwa byuburyo bukora, kuburyo icyuma gisohora imiyoboro irekura ingendo, bityo bikagabanya uruziga.

Mu myitozo, igikoresho cyo gutinda gishobora kongerwaho kugirango umuzenguruko ushobora guhagarikwa nyuma yimikorere yo guhinduranya irangiye mugihe cyagenwe.

Iyo umuyoboro mugari muto unyuze mumashanyarazi, icyuma hafi yumuhuza kirashonga kandi kigakururwa nubushyuhe bwumuriro bitewe ningufu za arc kinetic nubushyuhe bukabije buterwa no gushonga kwa contact, bityo bikagabanya umuyoboro.

Iyo amashanyarazi yafunzwe cyangwa umuzenguruko uhujwe nayo birananirana, icyuma cyumuzunguruko kirashobora kumena uruziga mugihe gito.

Ukurikije imiterere yuburyo igabanijwemo ibice, bigendanwa kandi bihagarikwa bitatu.

Ukurikije uburyo bwo kurekura bugabanijwemo intoki n'amashanyarazi muburyo bubiri.

Ukurikije uburyo bwo gukora bushobora kugabanywa mukwirakwiza umukandara kandi nta guhererekanya umukandara ubwoko bubiri;

Ibyiciro

(1)Inzitizi zumuzingiIrashobora kugabanywamo icyumba cyo guhagarika icyumba (VHV), irembo rya arc ihagarika (AVR), kurekura vacuum (VSD) hamwe n’umuhuza wa vacuum ukurikije uburyo bwo guhagarika arc.

Ibipimo byihariye

Ubwoko bwumuzunguruko umeze nkibindi bikoresho byamashanyarazi, nka kode igizwe ninyuguti "P", "Y" nimibare yo guhinduranya, hamwe na code igizwe ninyuguti "C" nimibare yo guhinduranya ibyuma. , nibindi, ariko imikorere yabo nimiterere biragaragara ko bitandukanye kandi mubisanzwe ntibishobora gukoreshwa mubikorwa rusange.Fata ZF6 na ZF14 kurugero.

3) Ikigereranyo cyagenwe: bivuga icyerekezo kinini cyimirimo ikora yamashanyarazi ishobora kwihanganira mubihe byagenwe.

4. "Ubushobozi bwo kumena" bivuze ko icyuma cyumuzunguruko gishobora guhagarika byimazeyo AC 50Hz cyangwa DC 1000V cyangwa munsi yacyo mugihe cyagenwe, kandi igihe cyo kumena ntigishobora kurenga 5ms.

5) Ibiranga imikorere

Ihame ryo guhitamo

1 、 Igabanyijemo:

.Imashanyarazi yamashanyarazi ifite ibyiza byo gukora bidakunze kubaho kandi byoroshye, ariko birasabwa guhagarika amashanyarazi mugihe umurongo na moteri biremereye cyangwa bigufi cyane kugirango birinde impanuka kwaguka.Kubwibyo, kumena inzitizi bigomba kuba byujuje ibisabwa kugirango uhagarike amashanyarazi mugihe cyagenwe, hamwe nigihe gito cyo kumeneka, guhitamo neza nibindi.

. imiterere yimbere yibikoresho byamashanyarazi kugirango byuzuze ibisabwa mukurinda moteri no kugenzura imiyoboro ya AC.Mubyongeyeho, ifite kandi relay irenze, rezo ya volvoltage na zeru zikurikirana.
