Miniature yamashanyarazi ni ubwoko bwa switchgear ya voltage ntoya, ikoreshwa mukurinda ibikoresho byamashanyarazi numutekano wawe.
Imashini ntoya yamashanyarazi irashobora gushyirwaho haba mumazu (kurugero, mumabati yo kugabura) cyangwa hanze (urugero, mumasanduku yo kugabura).
1. Hariho ubwoko butatu bwuburyo bwo kwishyiriraho: gukosorwa, kugendanwa no guhagarikwa.
2. Umuyoboro wapimwe wumurongo wumurongo ugabanijwe mubwoko bwa N na P, N numuyoboro hamwe numuyoboro ntarengwa wagenwe, P nuwo munsi hamwe nu munsi ntarengwa wagenwe, naho N igabanyijemo L, L, N ni 1,2 -3A, na B ni 2A ukurikije icyerekezo cyagenwe.
Imashini ntoya yamashanyarazi irashobora gukoreshwa mumazu, amazu y'ibiro, inganda n'ahandi.
I. Gutondekanya ibice bito byumuzunguruko.
.
Sisitemu yo mu kirere ikwiranye na AC yo gukwirakwiza amashanyarazi make hamwe na voltage yagabanutse kugera kuri 690V kandi ntishobora kwihanganira ubwoko ubwo aribwo bwose bwo kunanirwa kw’umuzunguruko mugihe imirongo itabogamye (N) na zeru (D) ihujwe, kuko hari imyuka myinshi ya inert muri ikirere.
Byongeye kandi, sisitemu ifite voltage yagereranijwe ya 690V (N) cyangwa irenga (hejuru ya 1800V) ntishobora kunyura mumiyoboro yicyuma cyangwa amasahani.
Sisitemu ya Vacuum ikwiranye na voltage yagenwe kuri 660V, umutwaro muremure kandi nta murongo wikosa uhari.
(2) Bishyizwe muburyo bukoreshwa: hari ubwoko bubiri: imikorere yintoki nigikorwa cyikora.
Igikorwa cyintoki: gikoreshwa muguhuza cyangwa kumena uruziga rusanzwe numuzunguruko udasanzwe, umukoresha wintoki anyuze mumaboko, intoki cyangwa buto kugirango abigereho.
Igikorwa cyikora: binyuze mumuzunguruko uhindura kuri bouton igenzura, kugirango ugere kumirimo isabwa.
.
Imwe ni imashini;ikindi ni electrodinamike.
Imashini yumuzunguruko ikoreshwa cyane cyane kuri 50HZ AC, 660V DC, sisitemu yo hejuru ya voltage.
Electrodynamic action circuit yameneka ikoreshwa cyane muri sisitemu ya AC 1000V cyangwa umurongo wo gukwirakwiza voltage nkeya;ubundi bwoko nka fus, reaction, switch birashobora kuba birenze-kurinda no kugenzura.
Imashanyarazi yamashanyarazi yamashanyarazi igabanijwemo ibikoresho byohereza ikirere hamwe nigikoresho cyohereza ibikoresho.
.
Sisitemu yo kuzimya arc irashobora kugabanywamo ibyiciro bibiri: umurongo utabogamye hamwe numurongo utabogamye.Iyambere irashobora gukoreshwa mumuzunguruko utabogamye kubikorwa bitandukanye, iyanyuma ntishobora gukoreshwa mumirongo yose itabogamye (nk'amazu yo guturamo n'inzu y'ibiro), naho iyanyuma ikoreshwa cyane muburyo bwose bw'imirongo y'amashanyarazi (nk'inyubako zinganda nububiko) usibye gutura.
Sisitemu yo kuzimya amashanyarazi arc irashobora gukoreshwa mumuzunguruko wose ukeneye kurinda umurongo w'amashanyarazi impanuka y'amashanyarazi;irashobora gukoreshwa mumuzunguruko wose ukeneye kurinda umurongo w'amashanyarazi impanuka y'amashanyarazi udafite umurimo wo kurinda cyangwa udafite umurimo wo kurinda mubikorwa rusange.Sisitemu yo kuzimya amashanyarazi ya arc irashobora gukora "umuzunguruko mugufi" hagati yinkomoko yumuriro, umutwaro numurongo utabogamye, ushobora guca amashanyarazi vuba kugirango ugabanye imitwaro yaka umuriro.
(5) Gutondekanya kumikorere: hariho unipolar na breakolar breakers;ubwo buryo bwombi bushobora gukoreshwa mumirongo yumuriro cyangwa gukwirakwiza kabine, bita icyiciro kimwe na moteri nyinshi zumuzunguruko (ni ukuvuga kugira ibyiciro bibiri cyangwa byinshi) hamwe nu byiciro bibiri byumuzunguruko (bizwi kandi nkibice bitatu byumuzunguruko);icyiciro kimwe nicyiciro cya kabiri cyumuzunguruko gifite ibice byihariye byo kugenzura, nka: ibyiciro bitatu-bigabanya imiyoboro yamashanyarazi, nibindi.;ibyiciro bibiri byumuzunguruko bikoreshwa cyane cyane muri sisitemu yo gukwirakwiza 10 kV cyangwa munsi yayo, cyangwa nka sisitemu yo gukingira mumabati yo gukwirakwiza 10 kV cyangwa munsi.
