I-Circuit Breakers echazwe: uKhuselo, uHlelo, kunye nokusetyenziswa
Yintoni iCircuit Breaker?
Ii-Circuit breakers zizixhobo eziphambili zokukhusela ezisetyenziselwa ukunqumla ngokuzenzekelayo iisekethe eziphosakeleyo kwiinkqubo zombane. Imisebenzi yabo ephambili ibandakanya ukukhuselwa komthwalo ogqithisiweyo, ukhuseleko lwesiphaluka esifutshane, kunye nokuhlukaniswa kombane.
Izaphuli zesekethe zihlelwa ngokwesicelo zibe I-Miniature (MCB), i-Molded Case (MCCB), Air (ACB), iVacuum (VCB), kunye neNtsalela yangoku (RCCB/RCBO) iintlobo.
Basebenza nge thermal (umthwalo ogqithisileyo) kwaye kazibuthe (isiphaluka esifutshane) iindlela zokukhubeka ze uqhawulo olukhawulezayo.
Kwi iinkqubo zokulawula iimoto, iziqhekeza zisebenza njenge iiswitshi zokukhusela eziphambili, esebenza kunye abafowunelwa (ulawulo olude) kwaye iireyilayi ze-thermal (ukukhusela umthwalo ogqithisileyo).
Ukukhetha kufuneka iqwalasele irethiwe yangoku, ukophula umthamo, inani lepali, kwaye ijika elijikayo (umz., uhlobo C lokhuselo lwemoto olusemgangathweni) ukudibanisa umthwalo kunye nenkqubo idinga ngokuchanekileyo.
