Isiphazamisi seVacuum yeMV VCB, VS1 ZN28 ZN63

Iinkcukacha zeMveliso

Iithegi zeMveliso

Inkcazo emfutshane yemveliso:

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.
Ubuninzi bomphunga buxhomekeke kumbane kwi-arcing.Ngenxa yokuhla kwemowudi yamaza angoku isantya sokuphuma komphunga kwaye emva koziro wangoku, indawo ephakathi iphinda ifumane amandla ayo edielectric ebonelelwe ngoxinzelelo lomphunga olujikeleze unxibelelwano oluncitshisiweyo.Ngenxa yoko, i-arc ayiphindi inqande kwakhona ngenxa yokuba umphunga wesinyithi ukhutshwa ngokukhawuleza kwindawo yoqhagamshelwano.

Qwalasela

Lawula ngokungqongqo isantya sokuvala kunye nokuvula i-vacuum circuit breaker.
Kwi-vacuum circuit breaker kunye nesakhiwo esithile, umenzi uye wachaza isantya esiphezulu sokuvala.Xa isantya sokuvala i-vacuum circuit breaker siphantsi kakhulu, ukunxiba koqhagamshelwano kuya kwanda ngenxa yokwandiswa kwexesha lokuqhekeka kwangaphambili;Xa i-vacuum circuit breaker inqanyuliwe, ixesha le-arcing lifutshane, kwaye ixesha layo eliphezulu le-arcing alidluli i-1.5 yamandla e-half wave wave.Kudingeka ukuba xa i-current iwela i-zero okokuqala, igumbi lokucima i-arc kufuneka libe namandla okwaneleyo okukhusela.Ngokuqhelekileyo, kulindeleke ukuba i-stroke yoqhagamshelwano kwi-frequency ye-half wave iya kufikelela kwi-50% - 80% ye-stroke epheleleyo ngexesha lokuphulwa kwesekethe.Ngoko ke, isantya sokuvula i-breaker circuit kufuneka silawulwe ngokungqongqo.Njengoko igumbi lokucima i-arc le-vacuum ye-vacuum breaker ngokubanzi lithatha inkqubo yokubrawuza, amandla ayo omatshini akakho phezulu, kwaye ukuxhathisa kwayo kukungcangcazela.Isantya esiphezulu kakhulu sokuvala i-breaker circuit siya kubangela ukungcangcazela okukhulu, kwaye kuya kuba nefuthe elikhulu kwi-bellows, ukunciphisa ubomi benkonzo ye-bellows.Ngoko ke, isantya sokuvala i-vacuum ye-circuit breaker idla ngokusetwa njenge-0.6 ~ 2m / s.
