Kuenzaniswa nemamwe mabreaker edunhu, iyo nheyo yekushanda yevacuum circuit breaker yakasiyana neiyo arc yekudzima svikiro.Iko hakuna conductive medium muvacuum, iyo inoita kuti arc ibve nekukurumidza.Naizvozvo, kupatsanurwa pakati peakasimba uye static mabatiro edunhu anotyora idiki kwazvo.
Insulation maitiro evacuum
Vacuum ine yakasimba insulation maitiro.Mune vacuum circuit breakers, gasi rakatetepa kwazvo, kufamba kwemahara kwemamorekuru egasi kwakakura, uye mukana wekudhumhana idiki kwazvo.Naizvozvo, kudhumhana dissociation haisiriyo chikonzero chikuru chekuparara kwenzvimbo yechokwadi, asi zvimedu zvesimbi zvakanyungudutswa ne electrode pasi pechiito chesimba remagetsi emagetsi ndicho chinhu chikuru chinokonzera kukanganisa kwekudzivirira.
Kusimba kwesimba muvacuum gap hakungobatanidzi nekukura kwegomba uye kufanana kwemunda wemagetsi, asiwo zvakanyanya kukanganiswa nemidziyo ye electrode zvinhu uye pamusoro pemamiriro.Pasi pemamiriro ediki diki gap (2-3 mm), iyo vacuum gap ine yakakwirira insulation hunhu pane yakanyanya kudzvanywa mweya uye SF6 gasi, ndicho chikonzero nei kuvhurika kwenzvimbo yevacuum circuit breaker kazhinji kudiki.
Kupesvedzera kwezvinhu zve electrode pamagetsi ekuparara kunonyanya kuratidzwa musimba remagetsi (tensile simba) rezvishandiso uye nzvimbo yekunyungudika yesimbi zvinhu.Iyo yakakwirira yekusimba kwesimba uye nzvimbo yekunyunguduka, ndiko kuwedzera kwesimba rekudzivirira re electrode pasi pevacuum.
kushanda musimboti
Kana iyo yakakwira vacuum yemhepo ikozvino inoyerera nepakati zero point, iyo plasma inokurumidza kupararira uye kudzima arc kuti ipedze chinangwa chekucheka ikozvino.
