Iindaba zeshishini

Ii-Circuit breakers kunye ne-disconnectors zinokuphazamisa zombini iisekethe. Ngokuxhomekeke kwinani lezibonda, banokusebenza kwisigaba esisodwa okanye kwiisekethe ezithathu.

Ukutshintsha okufakwe kwipali luhlobo lokhuseleko olufakwe kwiipali zoncedo ukuqinisekisa ukhuseleko lombane. Umsebenzi wayo oyintloko kukuhlukanisa i-voltage ephezulu yesekethe.

Kwiinkqubo zangaphandle zokuhambisa amandla ombane aphezulu, i-40.5KV isebenza njengenqanaba lamandla ombane ongundoqo kwindawo yombane ophakathi-phezulu, isenza imisebenzi ebalulekileyo efana nokuhanjiswa kwamandla, ukugcinwa kwezixhobo zodwa.

I-12kV yangaphakathi ye-SF₆ iswitshi yomthwalo yinqanaba lesithathu le-AC high-voltage load switch kunye ne-voltage elinganisiweyo ye-12kV, ilungele ukufakwa kwangaphakathi. Isebenzisa i-SF₆ igesi njenge-insulating kunye ne-arc-extinguishing medium.
