Ubume kunye nokukhuselwa kwee-high-voltage pole-mounted circuit breakers

Iiswitshi efakwe kwipaliluhlobo lokutshintsha kokhuseleko olufakwe kwiipali zoncedo ukuqinisekisa ukhuseleko lombane. Umsebenzi wayo oyintloko kukuhlukanisa i-voltage ephezulu yesekethe. Izitshixo ezixhonywe epalini zineenguqu ezibalulekileyo ngokwemigaqo yokusebenza, ulwakhiwo, kunye neemeko zesicelo. Kwinkqubo yamandla, ngamnye udlala indima ekhethekileyo kunye nokugcina ngokudibeneyo ukhuseleko kunye nokusebenza okuzinzile kwegridi yamandla.

I-column-mounted circuit breaker kunye nokutshintsha komthwalo

Ukutshintshwa komthwalo we-pole-mounted unemisebenzi yokuqhawula umthwalo wangoku kunye nokuvala i-short-circuit current, kodwa ayikwazi ukuphula i-short-circuit current. Isetyenziselwa ubukhulu becala ukwahlulahlula komgca.

I-pale-mounted circuit breaker ingavala, ithwale kwaye ivule umbane oqhelekileyo wesiphaluka sokusebenza. Isenokuvala, iphathe kwaye ivule umsinga omfutshane ochaziweyo ngaphakathi kwexesha elimiselweyo. Ingasetyenziselwa njengokhuselo oluphambili lomgca kwaye lusetyenziswa ikakhulu kwiiswitshi ezinkulu zesebe. Umthamo wayo wokuvula unamandla kwaye inani lokuvula kunye nokuvala ngokulandelelana likhulu.

Indlela yokusebenza

Ukutshintshwa komthwalo kuqhutywe ngesandla kwaye kufuna ukungenelela komntu ukuvula okanye ukuvala isiphaluka.

I-breaker circuit sisixhobo esisebenza ngokuzenzekelayo. Xa kukho i-overload okanye isiphaluka esifutshane kwisekethe, i-breaker circuit iya kukhwela ngokuzenzekelayo kwaye inqumle okwangoku.

Ukuchaswa kokuqhekeka kunye nemisebenzi yokukhusela

Ukutshintsha komthwalo ngokuqhelekileyo kunomthamo ophantsi wokuqhawula kwaye ufanelekile imithwalo emincinci kunye neemeko ezingagqithisiyo. Zisetyenziselwa ikakhulu ukulawula ukuvulwa nokuvalwa kweesekethe. Nangona kunjalo, ngokwesiqhelo abanalo ukhuseleko lomthwalo omninzi okanye imisebenzi yokhuseleko lwesekethe emfutshane kwiimpazamo ezinjengomthwalo ogqithisileyo kunye neesekethe ezimfutshane.

I-breaker circuit inomthamo ophezulu wokuphuka kwaye inokusingatha imisinga emikhulu kunye neziphene ezinzima. Ayigcini nje ukunqumla isiphaluka kodwa inokukhusela ngokugqithisileyo kunye nemisebenzi yokukhusela i-short-circuit, ekwazi ukufumanisa ngokukhawuleza kunye nokunqumla umsinga ophosakeleyo.
