Umkhiqizo
Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)
Incazelo emfushane yomkhiqizo:
I-vacuum circuit breaker ine-insulating medium ephezulu yokushabalala kwe-arc uma kuqhathaniswa nesinye isiqhelisi sesekethe.Ukucindezela ngaphakathi kwesiphazamisi se-vacuum cishe ku-10-4 torrent futhi kulokhu kucindezela, ama-molecule ambalwa kakhulu akhona kusiphazamisi.I-vacuum circuit breaker inezindawo ezimbili ezimangalisayo.
Imvilophu yangaphandle ye-vacuum circuit breaker yenziwe ngengilazi ngoba imvilophu yengilazi isiza ekuhloleni i-breaker ngaphandle ngemva kokuhlinzwa.Uma ingilazi iba Milky kusukela ekupheleni kwasekuqaleni kwesibuko se-silvery, khona-ke kubonisa ukuthi i-breaker ilahlekelwa i-vacuum.
Ukunquma kwamanje ku-vacuum circuit breaker kuncike ecindezelweni lomhwamuko kanye nezakhiwo ze-electron ephumayo yento yokuxhumana.Izinga lokunquma liphinde lithonywe yi-thermal conductivity-yehlisa ukuqhutshwa kokushisa, okuphansi yizinga lokunquma.
Kungenzeka ukunciphisa izinga lamanje lapho ukuqotshwa kwenzeka khona ngokukhetha into yokuxhumana enikeza umhwamuko wensimbi owanele ukuvumela owamanje ukuba ufike enanini eliphansi kakhulu noma inani elinguziro, kodwa lokhu akuvamile ukwenziwa ngoba kuthinta kabi amandla e-dielectric. .
Izinyathelo zokuvimbela ukugcwala ngokweqile.I-vacuum circuit breaker inokusebenza okuhle kokuphuka.Kwesinye isikhathi lapho kuphulwa umthwalo ongenisayo, ukugcwala okukhulu kwe-overvoltage kukhiqizwa kuzo zombili iziphetho ze-inductance ngenxa yoshintsho olusheshayo lwe-loop current.Ngakho-ke, kuma-transformers ohlobo olomile kanye nezinye izinto zokusebenza ezinokumelana ne-voltage ephansi ye-impulse, kungcono ukufaka amadivaysi okuvikela ukuguquguquka kwe-overvoltage, njenge-metal oxide arresters.
Izici
1. Indlela yokusebenza incane, ivolumu iyonke incane, futhi isisindo silula.
2. Ingxenye yokuxhumana iyisakhiwo esivalwe ngokuphelele, esingeke sinciphise ukusebenza kwayo ngenxa yethonya lomswakama, uthuli, amagesi ayingozi, njll., futhi isebenza ngokuthembekile ngokusebenza okuzinzile kokuvala.
3. Ngomsebenzi wokuvala kabusha okuningi, ifanele izidingo zohlelo lokusebenza kunethiwekhi yokusabalalisa.
