Vacuum interrupter yeVXG (150)
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.
Mumagetsi edunhu, vacuum-interrupter yekubata zvinhu zvinonyanya kuita 50-50 copper-chromium alloy.Anogona kugadzirwa nekuisa simbi yemhangura-chrome alloy sheet panzvimbo yepamusoro nechepazasi yekusangana pamusoro pechigaro chekubatanidza chakagadzirwa nemhangura isina oxygen.Zvimwe zvinhu, senge sirivheri, tungsten uye tungsten makomisheni, anoshandiswa mune mamwe madhizaini ekukanganisa.Iyo vacuum interrupter's contact structure ine simba guru pakutyoka kwayo, kusimba kwemagetsi uye nhanho yekutema ikozvino.
Zvikamu zvevacuum interrupter zvinofanirwa kunyatsocheneswa musati maungana, sezvo zvinosvibisa zvinogona kubudisa gasi muhamvuropu yevacuum.Kuti ive nechokwadi chekuparara kwakanyanya kwemagetsi, zvikamu zvinounganidzwa muimba yakachena umo huruva inodzorwa zvakanyanya.
Mushure mekunge nzvimbo dzapera uye dzakacheneswa ne electroplating uye kuongororwa kwemaziso kwepamusoro-soro yezvikamu zvose zvaitwa, iyo inovhiringidza inounganidzwa.High-vacuum solder inoshandiswa pazvisungo zvezvikamu, zvikamu zvakarongeka, uye zvinokanganisa zvinogadziriswa.Sezvo utsanana panguva yegungano inonyanya kukosha, mabasa ose anoitwa pasi pemamiriro e-air-conditioned clean-room.
Vagadziri vevacuum-interrupter vanogadzirisa izvi zvinonetsa nekusarudza zvinhu zvekubata uye magadzirirwo ekuderedza kutema kwazvino.Kuchengetedza michina kubva pakuwedzeredza, vacuum switchgears inowanzo sanganisira mavhisi anosunga.
Vacuum arc yekudzimisa kamuri yakakamurwa kuita arc yekudzimisa kamuri yedunhu rebreaker, load switch uye vacuum contactor.Iyo arc yekudzimisa kamuri yedunhu breaker inonyanya kushandiswa kune substations uye magetsi gidhi zvivakwa muchikamu chemagetsi, uye iyo arc yekudzima kamuri yekuremedza switch uye vacuum contactor inonyanya kushandiswa kune yekupedzisira vashandisi vemagetsi grid.
