Guhagarika icyuho kugirango uhindure imitwaro （205A）

Mubihe bimwe na bimwe, icyuho cyumuzunguruko gishobora guhatira umuyoboro wumuzunguruko kugeza kuri zeru mbere ya zeru karemano (no guhindukira kwumuyaga) mukuzunguruka-kuzunguruka.Niba ibikorwa byo guhagarika igihe bitameze neza kubijyanye na AC-voltage yumurongo (mugihe arc yazimye ariko imibonano iracyagenda kandi ionisation itarakwirakwira), voltage irashobora kurenga icyuho cyihanganira voltage.Ibi birashobora kongera gutwika arc, bigatera imigezi yinzibacyuho itunguranye.Birashoboka kugabanya urwego rugezemo aho gutemagura biboneka muguhitamo ibikoresho byitumanaho bitanga imyuka ihagije yicyuma kugirango ibyuka bigere kumurongo muto cyane cyangwa agaciro ka zeru , ariko ibi ntibikunze gukorwa kuko bigira ingaruka kumbaraga za dielectric.
Muri iki gihe, hamwe no gukata gake cyane, kumena vacuum ntibishobora gutera ingufu zirenze urugero zishobora kugabanya insuline ziva mubikoresho bikikije.
Vacuum arc kuzimya chambre, izwi kandi nka vacuum switch tube, nikintu nyamukuru kigize amashanyarazi.Igikorwa cyacyo nyamukuru nugukora umuzunguruko kuzimya arc byihuse no guhagarika umuyaga nyuma yo guhagarika amashanyarazi binyuze mumashanyarazi meza ya vacuum muri tube, kugirango wirinde impanuka nimpanuka.
Guhuza bitwara uruziga rwumuzingi iyo rufunze, rukora amaherere ya arc iyo ifunguye.Byakozwe mubikoresho bitandukanye, bitewe nikoreshwa rya vacuum interrupter nigishushanyo cyigihe kirekire cyo guhura, gukira byihuse byumuvuduko ukabije, hamwe no kugenzura umuriro mwinshi bitewe no gutemwa kurubu.
Umuvuduko wa vacuum ufite ingabo zikikije imikoranire no kumpera yumusangirangendo, birinda ibintu byose byandikirana byavumbuwe mugihe cya arc guhurira imbere imbere y ibahasha ya vacuum.Ibi byagabanya imbaraga zo kubika ibahasha, amaherezo bikavamo arcing ya interrupter iyo ifunguye.Inkinzo kandi ifasha kugenzura imiterere yikwirakwizwa ryamashanyarazi-imbere imbere yo guhagarika, bigira uruhare runini rwo gufungura amashanyarazi.Ifasha gukuramo imbaraga zimwe na zimwe zakozwe muri arc, kongera igipimo cyo guhagarika igikoresho.
