Ihowuliseyili 40.5KV HW-12 ngaphandle ombane aphezulu AC vacuum wesekethe breaker VCB wesekethe breakers yueqing

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

Isishwankathelo

I-hW-12 yangaphandle yombane ophezulu we-AC vacuum circuit breaker yi-currentransformer yangaphandle yokuhambisa izixhobo zokusasaza nge-voltage ye-40.5k kunye ne-50H yesigaba esithathu se-AC. Isetyenziselwa ukuhambisa ukunqunyulwa kwenethiwekhi kunye nokucima. umthwalo wangoku, ulayishe ngaphezulu okwangoku kunye nokufutshane kwesekethe yangoku kwinkqubo yamandla. kufanelekile ukukhuselwa kunye nolawulo kwiinkqubo zokuhanjiswa kwamandla kwezitishi kunye namashishini amashishini kunye nezemigodi. ilungele iigridi zamandla asezilalini kunye neendawo eziqhutywa rhoqo. Ngokukodwa kufanelekile kwiimfuno zenethiwekhi yasezidolophini kunye nenethiwekhi yasemaphandleni
