Guhagarika icyuho cyo kohereza hanze TD-25.8 / 630-20 (186)

Vacuum interrupter nigikoresho cyumuyagankuba gikoresha amashanyarazi akoresha vacuum ikora ikora insuline arc kuzimya kandi ikanamenya imikorere yumuriro wumuriro wamashanyarazi hamwe numubano wafunzwe muri vacuum.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.Muri ubu buryo, guhagarika ubushobozi bwubu hamwe nubuzima bwa serivisi ya vacuum interrupter iratera imbere.
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 gutembera gutunguranye.Muri ibyo aribyo byose, ihungabana ryinjijwe muri sisitemu ishobora kuvamo imbaraga zirenze urugero.
Muri iki gihe, hamwe no gukata gake cyane, kumena vacuum ntibishobora gutera ingufu zirenze urugero zishobora kugabanya insuline ziva mubikoresho bikikije.
