Yintoni uMsebenzi weNgxowa-mali yeSekethe yeVacuum

Yintoni umsebenzi wei-vacuum circuit breaker?
I-1, i-Circuit breakers isetyenziselwa kakhulu ukuvula nokuvala iisekethe kwiinkqubo zamandla.Xa i-short-circuit iphutha lenzeka kwi-circuit, i-short-circuit current inganqunyulwa ngokuvala i-breaker circuit ngokukhawuleza, kwaye i-scope yengozi inokuthintelwa ukuba ikhulise.
I-2, i-breaker circuit ingasetyenziselwa ukulawula nokukhusela i-motor kunye ne-transformer, ngaloo ndlela idlala indima yokukhusela i-motor kunye ne-transformer.Ukongeza, inokusetyenziswa njengesixhobo sokubonisa umqondiso wesiphoso, ngoko ingasetyenziselwa ulawulo olukude, ukubeka iliso kwindawo ephakathi, ukubeka esweni ukusebenza kwezixhobo, kwaye inokusetyenziswa njengokhuseleko lwesiphaluka esifutshane xa kukho ukungaphumeleli komgca.
I-3, i-breaker circuit inokunqumla ngokukhawuleza umthwalo wangoku ngaphandle kokucinywa kwamandla.Xa isiphaluka sihluleka, umbane wangoku unokutshintshwa ukusuka kwindawo yokungaphumeleli ukuya kwindawo ekhuselekileyo, ngaloo ndlela unciphisa ixesha lokungaphumeleli kwamandla kunye nokuphepha ukulahlekelwa kwezoqoqosho okubangelwa ukuhluleka kwamandla.
I-4, i-breaker circuit ingasetyenziselwa ukukhusela i-motor short circuit, kwaye i-motor ayiyi konakaliswa ngenxa yeempazamo.
I-5, i-breaker circuit inokulawulwa ngumbane wesigaba sesithathu, esinokubonelela ngamaxabiso ombane ahlukeneyo ngamaxesha ahlukeneyo.
I-6, I-vacuum ye-breaker circuit ineempawu zomthamo omncinci, ubunzima obulula, ukuthembeka okuphezulu kunye nokunye ngenxa yokwamkela isakhiwo sokucima i-arc yeqondo eliphezulu le-vacuum kunye nokumelana nokunciphisa okuphantsi.I-vacuum circuit breaker ibe yenye yezona zixhobo zombane ezisetyenziswa kakhulu kwisekethe ye-AC, ebizwa ngokuba "ngumgca wokugqibela wokukhusela" kwinkqubo yamandla.Okwangoku, i-vacuum circuit breakers isetyenziswa ngokubanzi kwinethiwekhi yokusabalalisa kwaye idlala indima ebalulekileyo.
7 、 Okwangoku, i-vacuum zesekethe izaphuli ezisetyenziswa ngokuqhelekileyo zinokwahlulwa zibe ziindidi ezintathu: i-gas insulation switch (GIS), i-arc yokucima i-medium yi-vacuum kunye ne-air insulation mode: igumbi lokucima i-arc yisakhiwo se-oxide yesinyithi.
