Umkhiqizo
Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)
Incazelo emfushane yomkhiqizo:
Isiphazamisi se-vacuum, esaziwa nangokuthi i-vacuum switch tube, siyingxenye eyinhloko yeswishi yamandla kagesi aphezulu aphakathi nendawo.Isetshenziswa kakhulu ohlelweni lokulawula ukudluliswa kwamandla nokusabalalisa, futhi isetshenziswa nasezinhlelweni zokusabalalisa i-metallurgy, imayini, i-petroleum, amakhemikhali, ujantshi wesitimela, ukusakaza, ukuxhumana kanye nezimboni zokushisisa imvamisa ephezulu.Isiphazamisi seVacuum sinezimpawu zokonga amandla , ukonga izinto ezibonakalayo, ukuvimbela umlilo, ukuvikela ukuqhuma, umthamo omncane, impilo ende, izindleko zokulungisa eziphansi, ukusebenza okuthembekile futhi akukho kungcola.Isiphazamisi se-vacuum sihlukaniswe ukusetshenziswa kwesiphazamisi kanye nokushintshwa komthwalo.Isiphazamisi se-circuit breaker sisetshenziswa kakhulu esiteshini esincane kanye nezinsiza zegridi yamandla emnyangweni wamandla kagesi.
Lalela
Lawula ngokuqinile isivinini sokuvala nokuvula se-vacuum circuit breaker.Ku-vacuum circuit breaker ngesakhiwo esithile, umenzi uchaze isivinini sokuvala esingcono kakhulu.Uma isivinini sokuvala se-vacuum circuit breaker siphansi kakhulu, ukuguga kokuxhumana kuzokhuphuka ngenxa yokwandiswa kwesikhathi sangaphambi kokuhlukana;Lapho i-vacuum circuit breaker inqanyuliwe, isikhathi se-arcing sifushane, futhi isikhathi saso esiphezulu se-arcing asidluli i-1.5 power frequency half wave.Kudingeka ukuthi lapho lamanje liwela uziro okokuqala ngqa, igumbi lokucisha i-arc kufanele libe namandla anele okufakwa ngaphakathi.Ngokuvamile, kulindelekile ukuthi ukushaywa kothintana naye ku-wave yesigamu samandla kuzofinyelela ku-50% - 80% we-stroke egcwele ngesikhathi sokuphulwa kwesifunda.Ngakho-ke, isivinini sokuvula se-breaker circuit kufanele silawulwe ngokuqinile.Njengoba igumbi lokucisha i-arc le-vacuum circuit breaker ngokuvamile lithatha inqubo yokubhula, amandla ayo okusebenza awaphezulu, futhi ukumelana kwayo nokudlidliza kuphansi.Isivinini esikhulu kakhulu sokuvala se-circuit breaker sizodala ukudlidliza okukhulu, futhi sizoba nomthelela omkhulu ekuvutheleni, kunciphise impilo yesevisi yokuvunguza.Ngakho-ke, isivinini sokuvala se-vacuum circuit breaker ngokuvamile sisethwa njenge-0.6 ~ 2m / s.
