Iziphuli zesekethe ezilungisekayozizinto ezibalulekileyo kwiinkqubo zombane ezibonelela ngokhuseleko olugqithisileyo kunye nolwe-short-circuit. Esi sixhobo senzelwe ukuphazamisa ngokuzenzekelayo ukuhamba kombane xa kufunyenwe iimeko ezingaqhelekanga, ukuthintela umonakalo kwinkqubo yombane kunye neengozi ezinokubakho ezifana nomlilo okanye ukutshayiswa kombane. Isici esihlengahlengiswayo se-circuit breaker sivumela useto lwayo lokuhamba ukuba lwenziwe ngokwezifiso, nto leyo eyenza ukuba ibe sisisombululo esiguquguqukayo kwiintlobo ngeentlobo zezicelo.
Enye yezona nzuzo ziphambili zee-circuit breakers ezihlengahlengiswayo kukuba ziyakwazi ukuziqhelanisa nemithwalo eyahlukeneyo yombane. Ngokulungisa useto lokuhamba, i-circuit breaker inokwenziwa ngokwezifiso kumanqanaba athile angoku, ukuqinisekisa ukhuseleko olufanelekileyo kwizixhobo ezixhunyiweyo. Oku kuguquguquka kuluncedo ngakumbi kwiindawo apho imithwalo yombane inokutshintshatshintsha, njengezakhiwo zoshishino okanye izakhiwo zorhwebo.
Ukongeza ekuguquguqukeni, iziphuli-seki ezihlengahlengiswayo zinokunyusa ukuchaneka kweesekethe zokhuseleko. Ukukwazi ukulungisa useto lokuhamba kuvumela impendulo echanekileyo ngakumbi kwiimeko zoxinzelelo olugqithisileyo, kunciphisa umngcipheko wokukhubeka okungeyonyani ngelixa kugcinwa ukhuseleko oluthembekileyo. Eli nqanaba lolawulo libalulekile kwizicelo ezibalulekileyo ezifuna ukubekwa esweni okuchanekileyo kwangoku, njengeendawo zolwazi okanye izibonelelo zonyango.
Ukongeza, ukusebenza okuhlengahlengiswayo kwe-circuit breaker kuvumela ukusombulula iingxaki kunye nokugcinwa okusebenzayo. Ngokutshintsha useto lokuhamba, iingcali zinokuphucula ngokulula iiparameter zokhuseleko ngokusekelwe kwiimfuno ezithile zenkqubo yombane. Oku akupheleli nje ekwenzeni lula inkqubo yokulungisa iingxaki kodwa kukwanceda nohlengahlengiso lwexesha elizayo njengoko inkqubo itshintsha.
Xa ukhetha i-circuit breaker ehlengahlengiswayo, kubalulekile ukuqwalasela uluhlu lwezicwangciso ezihlengahlengiswayo ezibonelelayo. Ezinye ii-circuit breaker zivumela ukuba i-trip current ihlengahlengiswe, ngelixa ezinye zinokubonelela ngokukhetha ukulungisa ixesha lokuhamba okanye iimpawu ze-curve. Ukuqonda ukulungiswa okupheleleyo kubalulekile ekuqinisekiseni ukuba i-circuit breaker inokuhlangabezana ngempumelelo neemfuno zokhuseleko zenkqubo yombane.
Kubalulekile ukuqaphela ukuba nangona ii-adjustable circuit breakers zibonelela ngeenzuzo ezininzi, ukufakelwa kunye noqwalaselo olufanelekileyo kubalulekile ekwandiseni ukusebenza kwazo. Ukusebenza nengcali enolwazi oluphezulu kwiinkqubo zombane kunye nokukhuselwa kwee-circuit kubalulekile ekuqinisekiseni ukuba ii-adjustable circuit breakers zisetwe ngokuchanekileyo kwaye ziyahambelana nemigangatho yoshishino.
Ngamafutshane, ii-circuit breakers ezihlengahlengiswayo zisisombululo esiguquguqukayo nesichanekileyo sokukhusela ii-circuits kwi-overcurrent kunye nee-short circuits. Useto lwayo lokuhamba oluhlengahlengiswayo, ukuguquguquka kunye nokuchaneka kwenza ukuba ilungele ukusetyenziswa ngeendlela ezahlukeneyo ukusuka kwiindawo zoshishino kunye nezorhwebo ukuya kwiindawo ezibalulekileyo. Ngokusebenzisa amandla ahlengahlengiswayo ee-circuit breakers, iinkqubo zombane zinokungenelwa kukhuseleko olulungiselelwe wena kunye nokuthembeka okuphuculweyo, ekugqibeleni kunegalelo kukhuseleko kunye nokusebenza kakuhle kweziseko zophuhliso zonke.
