Ulawulo loshishino 12KV VS1 yangaphandle cleaner wesekethe full VCB

I-HWZN63 (VS1) ikhefu lesekethe yangaphandle (emva koku ekubhekiswa kuyo njengesiphathi sesekethe) sisixhobo sokuhambisa ngaphandle esinamandla alinganisiweyo e-12kV kunye nesigaba sesithathu se-ac ye-50Hz. Isetyenziselwa ikakhulu umthwalo wangoku, ukulayisha ngaphezulu ngoku kunye nokujikeleza kwesekethe yangoku kwinkqubo yamandla Kufanelekile ukukhuselwa kunye nokulawulwa kweenkqubo zokuhambisa umbane kwizitishi nakwimizi-mveliso kunye nakwimigodi.

Le breaker yesekethe ineempawu zobungakanani obuncinci, ubunzima bokukhanya, anti-ukufuma, ukugcinwa kwemivundla njalo njalo, inokuziqhelanisa neemeko zemozulu ezibi kunye nemeko emdaka.

1. I-4000A yangoku yekhabhinethi yokutshintsha kufuneka iqinise ukupholisa umoya
2 Xa umlinganiso weesekethe ezihamba kancinci ungaphantsi kwe-40KA, Q = 0.3s; xa umlinganiso omfutshane wesekethe yokuqhekeka okwangoku ungaphezulu okanye ulingana no-40KA, Q = 180s
