Isiphazamisi seVacuum yeMV VCB(iqokobhe leceramic, Umbane olinganisiweyo: 7.2kV-12kV)

Vacuum Arc recovery of Vacuum Circuit Breaker
Ivacuum ephezulu inamandla aphezulu kakhulu edielectric.Kwi-zero yangoku i-arc icinyiwe ngokukhawuleza, kwaye amandla e-dielectric asekwa ngokukhawuleza.Oku kubuyiselwa kwamandla e-dielectric kungenxa yesinyithi esiphuhliweyo esifumaneka kwindawo phakathi koqhagamshelwano lusasazeka ngokukhawuleza ngenxa yokungabikho kwee-molecule zegesi.Emva kokuphazamiseka kwe-arc, amandla okubuyisela ngexesha le-microseconds ezimbalwa zokuqala yi-1 kV/µs yesibini kwi-arc current ye-100A.
Ngenxa yolu phawu lukhankanywe apha ngasentla lwe-vacuum circuit breaker, luyakwazi ukusingatha izinto ezibuhlungu zokubuyisela ezihambelana neempazamo zomgca omfutshane ngaphandle kobunzima.

Ipropathi yezinto zoqhagamshelwano
Izinto zoqhagamshelwano ze-vacuum circuit breaker kufuneka zibe nale propati ilandelayo.

Ukusebenza iVacuum Circuit Breaker
Xa iphutha lenzeka kwinkqubo, abafowunelwa be-breaker bahanjiswa ngaphandle kwaye ngoko i-arc iphuhliswa phakathi kwabo.Xa abafowunelwa abaphetheyo bangoku batsalwa ngaphandle, ubushushu beendawo zabo zokuxhuma buphezulu kakhulu ngenxa yokuba kwenzeka ionization.Ngenxa ye-ionization, indawo yoqhagamshelwano izaliswe ngumphunga we-ion e-positive ekhutshwa kwizinto zoqhagamshelwano.

Umjikelo wolondolozo lwe-vacuum circuit breaker
I-vacuum circuit breaker ineempawu zokuthembeka okuphezulu, ubomi benkonzo ende kunye nokugcinwa kwexesha elide kunye nomjikelezo wokulungisa, kodwa ayinakuphosakela ukuba i-vacuum circuit breaker ayifuni ukugcinwa.Umjikelo wolondolozo kufuneka ulawulwe ngokuguquguqukayo ngokwemigaqo efanelekileyo kwaye udibanise neemeko zokusebenza zangempela.
