umgaqo woqhawulo-vacuum wangaphandle

Kwisekethe, i-circuit breaker isebenza nje nge-fuse, kodwa i-fuse inokusebenza kanye kuphela, ngelixa i-breaker circuit ingasetyenziselwa ngokuphindaphindiweyo.Ngethuba nje ixesha elikhoyo lifikelela kwinqanaba eliyingozi, linokubangela ngokukhawuleza isiphaluka esivulekileyo.ucingo oluphilayo kwisekethe luqhagamshelwe kuzo zombini iziphelo zokutshintsha.Xa iswitshi ibekwe kwimeko, yangoku iqukuqela ukusuka kwi-terminal esezantsi, ngokulandelelanayo nge-electromagnetic, i-contactor ehambayo, i-static contactor, kwaye ekugqibeleni isuka kwi-terminal ephezulu.

Okwangoku ingenza imagneti kwi-electromagnetic.Amandla ombane owenziwe yi-electromagnetic ayanda ngokunyuka kwangoku.Ukuba i-current iyancipha, amandla omagnetic nawo aya kuncipha.Xa utsiba lwangoku ukuya kwinqanaba eliyingozi, umazibuthe uya kuvelisa amandla kazibuthe amakhulu ngokwaneleyo ukutsala intonga yentsimbi eqhagamshelwe kunxibelelwano lokutshintsha.Oku kuthambekisa i-contactor ehambayo kude ne-static contactor, ethi yona inqumle isekethe.Umsinga uphazamisekile.

Izaphuli zesekethe ze-vacuum zangaphandle zingasetyenziselwa ukuhambisa amandla ombane, ukuqala iimotor ezi-asynchronous ngokungaqhelekanga, kunye nokukhusela iintambo zamandla kunye neenjini.Xa benomthwalo onzima okanye isiphaluka esifutshane kunye neempazamo ze-undervoltage, banokunqumla ngokuzenzekelayo isiphaluka.Umsebenzi wabo ulingana nokutshintsha kwe-fuse.Ukudibanisa ne-overheating relay njl. Kwaye emva kokuphula impazamo yangoku, akukho mfuneko yokutshintsha iindawo ngokubanzi.
