Guhagarika icyuho kugirango uhindure imitwaro （203）

Uburyo bukora bwo hanze butwara kwimuka, gufungura no gufunga uruziga.Guhagarika icyuho birimo akaboko kayobora kugenzura imiyoboro igenda no kurinda inzogera zifunga kutazunguruka, byagabanya ubuzima bwayo cyane.
Nubwo ibishushanyo bimwe na bimwe bya vacuum-interrupter bifite ibibuto byoroshye guhuza, imibonano isanzwe ikorwa hamwe nuduce, imirongo, cyangwa ibiti kugirango bongere ubushobozi bwabo bwo guca imigezi miremire.Umuyoboro wa Arc unyura muburyo bwimikorere itanga imbaraga za magneti kumurongo winkingi, ibyo bigatuma arc ihuza aho igenda yihuta hejuru yubusabane.Ibi bigabanya kwambara bitewe nisuri na arc, ishonga ibyuma byitumanaho aho bihurira.
Mubice byumuzunguruko, ibikoresho bya vacuum-interrupter nibikoresho byibanze ni 50-50 umuringa-chromium.Birashobora gukorwa mugusudira umuringa - chrome alloy urupapuro hejuru no hepfo yo guhuza hejuru yintebe yo guhuza ikozwe mumuringa utagira ogisijeni.Ibindi bikoresho, nka silver, tungsten na tungsten, bikoreshwa mubindi bishushanyo mbonera.Imiterere ya vacuum ihagarika imiterere ifite uruhare runini mubushobozi bwayo bwo kumeneka, kuramba kwamashanyarazi nurwego rwo gutema.
Iyo ihagaritse umubare runaka wubu, mugihe cyo gutandukana kwimikorere ihamye kandi ihagaze, ikigezweho kiragabanuka kugeza aho imibonano itandukana gusa, bikavamo kwiyongera gukabije kwurwanya hagati ya electrode no kwiyongera kwubushyuhe bwihuse, kugeza guhumeka ibyuma bya electrode bibaho, kandi mugihe kimwe, imbaraga zumuriro mwinshi cyane zirakorwa, bikavamo imyuka ihumanya cyane no gucika icyuho, bikaviramo arc vacuum.Iyo amashanyarazi yumurongo wa voltage yegereye zeru, kandi mugihe kimwe, kubera kwiyongera kwintera yo gufungura, plasma ya vacuum arc ikwirakwira vuba.Nyuma yimyuka ya arc itambutse zeru, uburyo bwo guhuza icyuho bwihuse buhinduka kuva kumuyoboro ukajya muri insulator, bityo ikigezweho kikaba cyaciwe.Bitewe nuburyo bwihariye bwo guhuza, icyuho cyo guhuza kizatanga umurima muremure wa magnetiki mugihe cyo guterana.Uyu murima wa magneti urashobora gutuma arc ikwirakwizwa neza hejuru yubusabane, ikagumana voltage ntoya ya arc, kandi bigatuma icyumba kizimya vacuum arc gifite umuvuduko mwinshi wo gukira imbaraga za post dielectric ya post arc, bikavamo ingufu nto za arc nigipimo gito cya ruswa.
