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
Ii-Withdrawer circuit breakers zinoyilo olulodwa lwendlela oluvumela ukuba zifakwe okanye zisuswe lula kwi-switchboard. Olu phawu luluncedo kakhulu ekulungiseni nasekusombululeni iingxaki njengoko lunciphisa ixesha lokungasebenzi kwaye lunciphisa isidingo sokufakelwa kwakhona kwentambo. Indlela yedrowa idla ngokuquka iseti yee-rails kunye nezihlanganisi ezivumela i-circuit breaker ukuba ingene kwaye iphume ngokulula endlwini yayo.
Iingenelo zee-circuit breakers ezinokurhoxiswa
Eyona nzuzo iphambili yee-circuit breakers ezinokurhoxiswa kukukwazi kwazo ukwenza kube lula ukugcinwa ngokukhawuleza nangokufanelekileyo. Xa kufika ixesha lokutshintsha okanye ukulungisa i-circuit breaker, uyilo olufana nedrowa luvumela ukususwa ngokukhawuleza kunye nokutshintshwa ngaphandle kokususa inani elikhulu leentambo. Oku akugcini nje ngokusindisa ixesha kodwa kunciphisa nomngcipheko weempazamo ngexesha lokugcinwa. Ukongeza, ii-circuit breakers ezitsalwayo zinokuvavanywa kwaye zihlolwe ngokulula ngelixa zingaphandle kwe-switchboard ukuqinisekisa ukuba zikwimeko yokusebenza ngokuchanekileyo ngaphambi kokuba ziphinde zisetyenziswe.
Enye inzuzo yeziphuli zesekethe ezinokutsalwa yi-drainage kukuba zisebenza ngeendlela ezahlukeneyo. Ezi ziphuli zesekethe zingasetyenziswa kwiindlela ezahlukeneyo zokusebenza, ukusuka kwizakhiwo zoshishino ukuya kwizakhiwo zorhwebo kunye neepropati zokuhlala. Kulula ukuzisusa nokuzitshintsha, nto leyo eyenza zibe lukhetho olufanelekileyo kwiindawo apho ixesha lokungasebenzi kufuneka lincitshiswe kwaye ukulungiswa kube lula.
Usetyenziso lwezaphuli zesekethe ezinokurhoxiswa
Iziphuli zesekethe zedrowa zidla ngokusetyenziswa kwiinkqubo zombane ezibalulekileyo apho ukuthembeka nokufikeleleka kubaluleke kakhulu. Zihlala zifumaneka kumaziko edatha, ezibhedlele, kwimizi-mveliso, nakwezinye iindawo ezifuna umbane ongaphazanyiswa. Kwezi meko, iziphuli zesekethe zedrowa zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko nokuthembeka kweziseko zombane.
Ukongeza, ii-drawout circuit breakers zisetyenziswa kwiinkqubo zamandla avuselelekayo ezifana nokufakelwa kwamandla elanga kunye nomoya. Uyilo olufana nolwedrowa luvumela ukugcinwa kunye nokulungiswa okusebenzayo kwee-circuit breakers, okunceda ukuphucula ukuthembeka kunye nokusebenza ngokubanzi kweenkqubo zamandla avuselelekayo.
Ngamafutshane, ii-drawout circuit breakers zibonelela ngesisombululo esisebenzayo kwiinkqubo zombane ezifuna ukugcinwa lula kunye nokukhuselwa okuthembekileyo. Uyilo lwazo olwahlukileyo luvumela ukususwa nokutshintshwa ngokukhawuleza, okwenza ukuba zilungele ukusetyenziswa ngeendlela ezahlukeneyo. Nokuba zikwindawo yemizi-mveliso, yezorhwebo okanye yokuhlala, ii-drawout circuit breakers zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kweenkqubo zombane.
