Khoom
Nqus interrupter rau MV VCB, VS1 ZN28 ZN63
Cov lus piav qhia luv luv ntawm cov khoom:
Thaum qhov kev ua txhaum tshwm sim hauv lub kaw lus, cov kev sib cuag ntawm lub breaker yog txav sib nrug thiab yog li lub arc yog tsim los ntawm lawv.Thaum cov neeg nqa tam sim no rub tawm sib nrug, qhov kub ntawm lawv cov khoom sib txuas yog siab heev vim qhov ionization tshwm sim.Vim yog ionization, qhov chaw sib cuag tau ntim nrog cov vapor ntawm cov ions zoo uas tau tawm ntawm cov khoom sib cuag.
Qhov ntom ntawm vapor nyob ntawm qhov tam sim no hauv arcing.Vim qhov txo qis ntawm cov nthwv dej tam sim no lawv qhov kev tso tawm ntawm vapor poob thiab tom qab xoom tam sim no, qhov nruab nrab rov ua dua nws lub zog dielectric muab vapor ceev nyob ib puag ncig cov neeg raug txo.Li no, lub arc tsis retrike dua vim hais tias cov hlau vapor yog sai sai tshem tawm ntawm qhov chaw tiv tauj.
Ua tib zoo mloog
nruj me ntsis tswj qhov kaw thiab qhib ceev ntawm lub tshuab nqus tsev Circuit Court breaker.
Rau lub tshuab nqus tsev vacuum breaker nrog ib tug qauv, cov chaw tsim tshuaj paus tau teev qhov zoo tshaj plaws kaw ceev.Thaum kaw ceev ntawm lub tshuab nqus tsev vacuum breaker tsawg dhau, qhov hnav ntawm kev sib cuag yuav nce vim qhov txuas ntxiv ntawm lub sijhawm ua ntej tawg;Thaum lub tshuab nqus tsev vacuum breaker yog disconnected, lub sij hawm arcing yog luv, thiab nws lub sij hawm arcing siab tshaj plaws tsis tshaj 1.5 lub zog zaus ib nrab nthwv dej.Nws yuav tsum tau hais tias thaum tam sim no hla xoom thawj zaug, lub arc extinguishing chamber yuav tsum muaj txaus rwb thaiv tsev lub zog.Feem ntau, nws xav tias stroke ntawm kev sib cuag nyob rau hauv lub zog zaus ib nrab nthwv dej yuav ncav cuag 50% - 80% ntawm tag nrho cov hlab ntsha tawg thaum lub sij hawm tawg.Yog li ntawd, qhov qhib ceev ntawm Circuit Court breaker yuav tsum nruj me ntsis tswj.Raws li lub arc extinguishing chamber ntawm lub tshuab nqus tsev Circuit Court breaker feem ntau siv cov txheej txheem brazing, nws lub zog txhua yam tsis siab, thiab nws qhov kev co tsis zoo.Ntau dhau lawm kaw cov kev nrawm nrawm yuav ua rau kev co kom zoo dua, thiab tseem yuav muaj feem cuam tshuam rau kev sib tw, txo qhov kev pabcuam lub neej ntawm lub neej.Yog li ntawd, qhov kaw ceev ntawm lub tshuab nqus tsev Circuit Court breaker feem ntau yog teem li 0.6 ~ 2m / s.
