Ibicuruzwa
Guhagarika Vacuum kuri MV VCB (igikonoshwa ceramic, Umuvuduko ukabije: 7.2kV-12kV)
Ibisobanuro muri make kubicuruzwa:
Gukata kurubu mumashanyarazi yamashanyarazi biterwa numuvuduko wumuyaga hamwe nibintu bya elegitoronike byangiza ibintu.Urwego rwo gutema narwo ruterwa nubushyuhe bwumuriro - munsi yubushyuhe bwumuriro, munsi ni urwego rwo gutema.
Birashoboka kugabanya urwego rugezemo aho gutemagura biboneka muguhitamo ibikoresho byitumanaho bitanga ibyuka byumuyaga bihagije kugirango byemere ko bigera kumurongo muto cyane cyangwa agaciro ka zeru, ariko ibi ntibikunze gukorwa kuko bigira ingaruka kumbaraga za dielectric nabi. .
Imbaraga zo gukingira cyane: Ugereranije nibindi bitangazamakuru bitandukanye byifashisha bikoreshwa mumashanyarazi yameneka ni uburyo bwiza bwa dielectric.Nibyiza kuruta ibindi bitangazamakuru byose usibye ikirere na SF6, bikoreshwa kumuvuduko mwinshi.
Iyo arc yafunguwe no kwimura itumanaho muri vacuum, guhagarika bibaho kuri zeru yambere.Hamwe no guhagarika arc, imbaraga zabo za dielectric ziyongera kugeza ku gipimo cyigihe ibihumbi ugereranije nabandi bamena.

(1) Ingamba zo gukumira umuvuduko ukabije.Vacuum circuit breaker ifite imikorere myiza yo kumena.Rimwe na rimwe, iyo ucitse imitwaro ya inductive, hejuru ya volvoltage ikorwa kumpera zombi za inductance kubera ihinduka ryihuse ryumuzingi.Kubwibyo, kubikoresho byumye byumye hamwe nibindi bikoresho bifite imbaraga zo kurwanya imbaraga za impulse nkeya, nibyiza ko ushyiraho ibikoresho birinda amashanyarazi arenze urugero, nkabafata ibyuma bya okiside.
(2) Kugenzura byimazeyo imizigo igezweho.
Ubushobozi burenze urugero bwa vacuum circuit breaker burakennye.Kubera ko ubushyuhe bwumuriro bukorwa hagati yo guhura nigikonoshwa cyumuzunguruko wa vacuum, ubushyuhe kuri contact hamwe ninkoni yayobora byanduzwa cyane ninkoni yayobora.Kugirango ubushyuhe bukore bwa vacuum yamashanyarazi itarenga agaciro kemewe, icyerekezo cyacyo kigomba kuba kigarukira cyane kugirango kiri munsi yikigereranyo cyagenwe.
