Vacuum interrupter yeMV VCB(ceramic shell, Rated voltage: 7.2kV-12kV)
Tsanangudzo pfupi yechigadzirwa:
Vacuum interrupter, inozivikanwawo sekuti vacuum switch chubhu, ndiyo yakakosha chikamu chepakati-yakakwirira voltage simba switch.Basa guru revacuum interrupter nderekuita kuti yepakati uye yakakwira voltage yedunhu ibvise magetsi evhacuum arc yekudzimisa kamuri yeceramic shell kuburikidza nekunakisisa kwekuvharira kwevacuum mukati mechubhu, iyo inogona kukurumidza kudzima arc uye kudzvinyirira ikozvino. , kuitira kudzivirira tsaona netsaona.
Vacuum circuit breaker ine yakakwira insulating medium yekutsakatika kwearc kana ichienzaniswa neimwe yedunhu inotyora.Dzvinyiriro mukati mevacuum interrupter inenge 10-4 torrent uye pakumanikidzwa uku, mashoma mamorekuru aripo mune inovhiringidza.Iyo vacuum yedunhu breaker ine kunyanya maviri phenomenal zvivakwa.
High insulating simba: Mukuenzanisa nemamwe akasiyana-siyana anodzivirira midhiya anoshandiswa mune redunhu breaker vacuum ndeye yepamusoro dielectric medium.Zviri nani kupfuura mamwe midhiya kunze kwemhepo uye SF6, iyo inoshandiswa pakumanikidza kwakanyanya.
Teerera
Nyatsodzora kuvhara nekuvhura kumhanya kwevacuum circuit breaker.
Kune iyo vacuum circuit breaker ine chimwe chimiro, mugadziri akatsanangura yakanakisa kuvhara kumhanya.Kana kukurumidza kwekuvhara kwevacuum circuit breaker kwakanyanya kuderera, kupfeka kwekusangana kuchawedzera nekuda kwekuwedzera kwenguva yekuparara kwepamberi;Kana iyo vacuum yedunhu breaker ikabviswa, nguva yekumisa ipfupi, uye iyo yakanyanya arcing nguva haipfuure 1.5 simba frequency hafu wave.Izvo zvinodikanwa kuti kana ikozvino yayambuka zero kekutanga, iyo arc yekudzima kamuri inofanirwa kuve neyakakwana yekusimbisa simba.Kazhinji, zvinotarisirwa kuti sitiroko yekusangana mumagetsi frequency hafu wave ichasvika 50% - 80% yekurohwa kwakazara panguva yekutyora kwedunhu.Naizvozvo, kumhanya kwekuvhura kwemutsigiri wedunhu kunofanirwa kudzorwa zvakanyanya.Sezvo iyo arc yekudzima kamuri yevacuum wedunhu breaker kazhinji inotora brazing process, simba rayo remuchina harina kukwirira, uye kuramba kwayo vibration kwakashata.Kunyanya kuvharika kwekumhanya kwedunhu rinotyora kunokonzeresa kuzunguzika kukuru, uye kuchavawo nekukanganisa kukuru pamabhero, kuderedza hupenyu hwebasa remabhero.Naizvozvo, iyo yekuvharisa yekumhanyisa yevacuum circuit breaker inowanzoiswa se 0.6 ~ 2m / s.
