Vacuum interrupter yeMV VCB, VS1 ZN28 ZN63
Tsanangudzo pfupi yechigadzirwa:
Kana kukanganisa kukaitika muhurongwa, mabatiro eanotyora anofambiswa akaparadzaniswa uye saka arc inogadzirwa pakati pavo.Kana iyo yazvino inotakura mameta inodhonzwa nepakati, tembiricha yezvikamu zvadzo zvekubatanidza yakakwira zvakanyanya nekuda kwekuti ionization inoitika.Nekuda kweiyo ionization, iyo nzvimbo yekubata inozadzwa nemhute yeiyo yakanaka ion inoburitswa kubva kune yekubata zvinhu.
Kuwanda kwemhute kunobva pane ikozvino mu arcing.Nekuda kwekudzikira kweave wave chiyero chekuburitswa kwemhute uye mushure meiyo zero yazvino, iyo yepakati inowanazve simba rayo redhielectric yakapihwa mhute density yakatenderedza mabatiro yakaderedzwa.Nekudaro, iyo arc haidzoke zvakare nekuti mhute yesimbi inobviswa nekukurumidza kubva munzvimbo yekusangana.
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.
