Iziphuli zesekethe zedrowazizinto ezibalulekileyo kwiinkqubo zombane, zibonelela ngokhuseleko lokugqithisa kunye nolwe-short-circuit. Olu hlobo lwe-circuit breaker luyilwe ukuba lususwe okanye lufakwe lula kwinkqubo, nto leyo evumela ukugcinwa nokutshintshwa ngokukhawuleza ngaphandle kokuphazamisa ukuseta umbane wonke. Kweli nqaku, siza kuhlola iimpawu, iingenelo, kunye nokusetyenziswa kwe-circuit breakers ezinokurhoxiswa.
Imisebenzi yezaphuli zesekethe ezinokurhoxiswa
I-circuit breaker enokutsalwa isebenzisa uyilo olulodwa lwendlela yokusebenza kwaye inokutsalwa lula kwindawo yokufaka i-switchboard. Olu phawu luvumela abasebenzi bokulungisa ukuba basuse ii-circuit breakers ukuze zihlolwe, zivavanye, okanye zitshintshwe ngaphandle kokuvala yonke inkqubo. Iindlela zokudonsa zihlala ziquka iseti yee-rails kunye nezihlanganisi ukuze kube lula ukususa nokufaka i-circuit breaker ngokulula.
Iingenelo zee-circuit breakers ezinokurhoxiswa
Uyilo lwedrowa olufana nolwe-circuit breaker lubonelela ngeenzuzo ezininzi ngokubhekiselele kulondolozo, ukhuseleko kunye nokuguquguquka. Enye yezona nzuzo ziphambili kukukwazi ukunciphisa ixesha lokungasebenzi ngexesha lokugcinwa okanye ukulungiswa. Ukusebenzisa ii-drawout circuit breakers kwenza kube lula ukususwa nokutshintshwa kwezixhobo, kunciphisa ixesha elifunekayo lokulungiswa, kwaye kunciphisa ukuphazamiseka kwenkqubo yombane.
Ukongeza, ii-drawout circuit breakers zivumela abasebenzi bokulungisa ukuba basebenzise i-circuit breaker kwindawo elawulwayo, nto leyo eyonyusa ukhuseleko. Ngenxa yokuba i-circuit breaker ingasuswa ngaphandle kokubeka izinto zombane eziphilayo, umngcipheko weengozi zombane uncitshiswa kakhulu. Olu phawu lubaluleke kakhulu kwiindawo zoshishino nezorhwebo apho iinkqubo zombane zinzima kwaye zinokuba yingozi.
Ukongeza, uyilo lwedrawout lubonelela ngokuguquguquka ngokwemigaqo yokuphuculwa kwenkqubo okanye uhlengahlengiso. Xa kufika ixesha lokutshintsha okanye ukuphucula idrawout circuit breaker, inkqubo yenziwa lula njengoko iyunithi inokususwa ngokulula kwaye itshintshwe ngomzamo omncinci. Olu kuguquguquka kunceda ukuphucula ukusebenza kakuhle kunye nokuthembeka kwenkqubo yombane.
Usetyenziso lwezaphuli zesekethe ezinokurhoxiswa
Iziqhekezi zesekethe zedrowa zisetyenziswa kakhulu kwiindlela ezahlukeneyo zokusebenza, kuquka izakhiwo zoshishino, izakhiwo zorhwebo, amaziko edatha kunye neenkqubo zokusasazwa kombane. Ukuguquguquka kwazo kunye nokulula kokugcinwa kwazo kuzenza zilungele iindawo apho umbane ongenakuphazamiseka ubaluleke kakhulu kwaye ixesha lokungasebenzi kufuneka lincitshiswe.
Kwiindawo zoshishino, ii-circuit breakers ezinokutsalwa zidla ngokusetyenziswa kwizicelo ezinzima ezifana nezityalo zokuvelisa, ii-refineries, kunye nemisebenzi yemigodi. Ukukwazi ukususa nokutshintsha ii-circuit breakers ngokukhawuleza kubalulekile ekugcineni ukusebenza okuqhubekayo kwezixhobo ezibalulekileyo kunye noomatshini.
Kwizakhiwo zorhwebo nakwiindawo zolwazi, ii-drawout circuit breakers zisetyenziselwa ukuqinisekisa ukusasazwa kwamandla okuthembekileyo nokukhuselekileyo. Ii-drawer circuit breakers kulula ukuzigcina zisemgangathweni kwaye zinokuphuculwa okanye zitshintshwe ngaphandle kokuphazamisa lonke ulwakhiwo lombane, nto leyo eyenza ukuba zibe zilungele ezi ndawo.
Ngamafutshane, ii-drawout circuit breakers zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko, ukuthembeka kunye nokusebenza kakuhle kweenkqubo zombane. Uyilo kunye nokusebenza kwazo okwahlukileyo zibonelela ngeenzuzo ezininzi, nto leyo eyenza ukuba ibe lolona khetho luphambili kwiintlobo ngeentlobo zezicelo. Nokuba kukwiindawo zoshishino, zorhwebo okanye kwiziko, ii-drawout circuit breakers zibonelela ngesisombululo esisebenzayo sokugcina nokukhusela ukufakwa kombane.
