Isimiso se-outdoor vacuum circuit breaker

Kumjikelezo, i-circuit breaker yenza njenge-fuse, kodwa i-fuse ingakwazi ukusebenza kanye kuphela, kuyilapho ama-circuit breaker angasetshenziswa ngokuphindaphindiwe.Uma nje i-current ifinyelela ezingeni eliyingozi, ingabangela ngokushesha isifunda esivulekile.intambo ephilayo kusekethe ixhunywe kuzo zombili iziphetho zeswishi.Lapho iswishi ibekwe endaweni, i-current igeleza isuka kutheminali engezansi, ilandelana ngozibuthe kagesi, isixhumi esithintayo esinyakazayo, isixhumi esimile, futhi ekugcineni sisuke kutheminali ephezulu.

Yamanje ingakwazi ukudonsa uzibuthe we-electromagnetic.Amandla kazibuthe akhiqizwa uzibuthe kagesi ayanda ngokukhula kwamandla.Uma okwamanje kuncipha, amandla kazibuthe nawo azokwehla.Lapho i-current igxumela ezingeni eliyingozi, uzibuthe kagesi uzokhiqiza amandla kazibuthe amakhulu ngokwanele ukudonsa induku yensimbi exhunywe ekuxhumekeni kweswishi.Lokhu kutshekisa i-contactor ehambayo kude ne-static contactor, yona enqamula isekethe.Umsinga uphazamisekile.

Ama-circuit vacuum angaphandle angasetshenziswa ukusabalalisa amandla kagesi, ukuqala ama-asynchronous motors njalo, futhi avikele izintambo zikagesi namamotho.Uma inomthwalo omkhulu noma i-short circuit kanye namaphutha e-undervoltage, inganqamula isekethe ngokuzenzakalelayo.Umsebenzi wabo ulingana neswishi ye-fuse.Inhlanganisela ne-overheating relay njll Futhi ngemva kokuphula iphutha lamanje, ngokuvamile asikho isidingo sokushintsha izingxenye.
