Guhagarika Vacuum kuri MV VCB (igikonoshwa ceramic, Umuvuduko ukabije: 7.2kV-12kV)

Vacuum Arc gukira kwa Vacuum Inzira yameneka
Icyuho kinini gifite imbaraga za dielectric nyinshi cyane.Kuri zeru zero arc irazimya vuba cyane, kandi imbaraga za dielectric zashizweho vuba cyane.Uku kugaruka kwingufu za dielectric ni ukubera ibyuma biva mu byuka biri hagati yimikoranire bikwirakwira vuba kubera kubura molekile ya gaze.Nyuma yo guhagarika arc, imbaraga zo kugarura mugihe microseconds yambere ni 1 kV / µs isegonda ya arc ya 100A.
Kuberako ibiranga byavuzwe haruguru biranga vacuum circuit breaker, irashobora gukemura ibibazo bikomeye byo kugarura ibintu bifitanye isano namakosa maremare ntakibazo.

Umutungo wibikoresho
Ibikoresho byandikirwa kumashanyarazi ya vacuum bigomba kugira imitungo ikurikira.

Gukora Umuyoboro Wumuzunguruko
Iyo ikosa ribaye muri sisitemu, imibonano ya breaker yimuwe hanyuma rero arc ikorwa hagati yabo.Iyo ibintu bitwara imibonano bikururwa, ubushyuhe bwibice byabo bihuza ni byinshi cyane bitewe na ionisation ibaho.Bitewe na ionisiyoneri, umwanya wo guhuza wuzuyemo imyuka ya ion nziza isohoka mubikoresho byo guhuza.

Kubungabunga cycle ya vacuum yamashanyarazi
Imashanyarazi ya vacuum ifite ibiranga kwizerwa cyane, kuramba kuramba hamwe nigihe kirekire cyo kubungabunga no gusana, ariko ntidushobora kwibeshya ko icyuma cyumuzunguruko kidakenera kubungabungwa.Inzira yo kubungabunga igomba kugenzurwa byoroshye hakurikijwe amabwiriza abigenga kandi igahuzwa nibikorwa nyabyo.
