Vacuum interrupter yeMV VCB(ceramic shell, Rated voltage: 7.2kV-12kV)
Tsanangudzo pfupi yechigadzirwa:
Ikozvino kutema muvacuum circuit breaker kunoenderana nekumanikidza kwemhute uye electron emission zvimiro zvechinhu chinobatika.Chiyero chekucheka chinokanganiswawo neiyo thermal conductivity-dzikisire thermal conductivity, yakaderera ndiyo yekucheka mwero.
Zvinogoneka kudzikisira nhanho iripo panochekwa nekusarudza chinhu chinobatika chinopa mhute yesimbi yakakwana kubvumira yazvino kuti iuye kune yakaderera kukosha kana zero kukosha, asi izvi hazviwanzo kuitwa nekuti zvinokanganisa simba re dielectric. .
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.
Kana arc ikavhurwa nekufamba nepakati pevanobatika muvacuum, kukanganisa kunoitika pazero yekutanga yazvino.Nekukanganiswa kwearc, simba ravo re dielectric rinowedzera kusvika pachiyero chezviuru zvenguva kana zvichienzaniswa nemamwe mabreak.
Teerera
(1) Matanho ekudzivirira kuwandisa.Vacuum circuit breaker ine yakanaka yekutyora kuita.Dzimwe nguva kana uchityora inductive mutoro, yakakwira overvoltage inogadzirwa kumativi ese maviri einductor nekuda kwekukurumidza shanduko ye loop ikozvino.Naizvozvo, kune yakaoma-mhando transformers uye zvimwe midziyo ine yakaderera impulse voltage resistance, zviri nani kuisa overvoltage ekudzivirira michina, senge metal oxide arresters.
(2) Nyatsodzora mutoro ikozvino.
Iyo yekuremedza huwandu hwevacuum circuit breaker haina kunaka.Sezvo kupisa kwemafuta kunoumbwa pakati pekusangana uye goko revacuum circuit breaker, kupisa pakubata uye conductive tsvimbo inonyanya kufambiswa pamwe neiyo conductive tsvimbo.Kuti uite tembiricha yekushanda yevacuum circuit breaker isapfuure kukosha kunobvumidzwa, iko kushanda kwayo kunofanirwa kuve kwakanyatso kuganhurirwa kuve yakaderera pane yakayerwa ikozvino.
