Ukuqonda Ukubaluleka KweIiMCCBkwiiNkqubo zoMbane
Kwicandelo leenkqubo zombane, i-MCCB (Molded Case Circuit Breaker) idlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kofakelo lonke. Eli candelo libalulekileyo lenzelwe ukukhusela iisekethe kwimithwalo emininzi kunye neesekethe ezimfutshane, ngaloo ndlela kuthintelwe umonakalo onokubakho kwizixhobo kunye nokuqinisekisa ukhuseleko lwabasebenzi.
Enye yeempawu eziphambili ze-MCCB kukukwazi kwayo ukuphatha imisinga ephezulu. Oku kuyenza ifaneleke kwiintlobo ngeentlobo zezicelo ukusuka koomatshini bemizi-mveliso ukuya kulwakhiwo lwezorhwebo. Ukukwazi ukuphatha imisinga ephezulu kuthetha ukuba ii-MCCB zinokukhusela ngokufanelekileyo kwimithwalo engaphezulu, eyenzeka xa umsinga ohamba kwisekethe udlula umthamo wawo olinganiselweyo. Kwimeko enjalo, i-MCCB iya kukhubeka kwaye iphazamise ukuhamba komsinga, ngaloo ndlela ithintele nawuphi na umonakalo kwisekethe okanye kwizixhobo ezixhunyiweyo.
Enye into ebalulekileyo kwi-MCCB kukukwazi kwayo ukukhusela kwiisekethe ezimfutshane. Isekethe emfutshane yenzeka xa uqhagamshelo olungalindelekanga luvela phakathi kwamanqaku amabini kwisekethe, nto leyo ebangela ukunyuka okukhulu kwamandla ombane ngequbuliso. Oku kunokubangela ubushushu obugqithisileyo kwaye mhlawumbi ingozi yomlilo. Ii-MCCB zenzelwe ukubona nokuphazamisa ngokukhawuleza ukuhamba kombane xa kusenzeka isekethe emfutshane, ngaloo ndlela zithintela nawuphi na umonakalo okanye ingozi enokubakho.
Ukongeza kumsebenzi wokukhusela, i-molded case circuit breaker ikwanayo nenzuzo yokuba kulula ukuyiseta kwakhona emva kokukhubeka. Oku kuthetha ukuba xa unobangela wokuxinana okanye i-short circuit isonjululwe, i-MCCB inokuphinda isetwe ukuze kubuyiselwe ukuhamba, kuncitshiswe ixesha lokungasebenzi kwaye kuqinisekiswe ukuqhubeka kwemisebenzi.
Ukongeza, ii-MCCB zincinci kwaye kulula ukuzifaka, nto leyo eyenza ukuba zibe lukhetho olufanelekileyo kwiintlobo ngeentlobo zezicelo. Ubungakanani bazo obuncinci busebenzisa kakuhle indawo kwii-switchboards nakwii-switchboards, ngelixa kulula ukuzifaka, nto leyo eyenza zibe lukhetho olulula kubakhi bombane kunye nabasebenzi bokulungisa.
Kufuneka kuqatshelwe ukuba ii-molded case circuit breakers kufuneka zikhethwe kwaye zifakwe ngokweemfuno ezithile zenkqubo yombane. Izinto ezinje ngovavanyo lwangoku, amandla okuphuka kunye nokuhambelana nezinye izixhobo zokukhusela kufuneka ziqwalaselwe ngononophelo ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
Ngamafutshane, ii-MCCB zidlala indima ebalulekileyo ekukhuseleni iinkqubo zombane kwi-overloads kunye nee-short circuits. Ukukwazi kwazo ukuphatha i-currents ephezulu, ukuthintela ukungasebenzi kakuhle kunye nokubonelela ngezakhono zokuseta kwakhona ezilula kwenza ukuba ibe yinxalenye ebalulekileyo yokuqinisekisa ukhuseleko kunye nokuthembeka kofakelo lombane. Ngokuqonda ukubaluleka kwee-MCCB kunye nokukhetha i-MCCB efanelekileyo kwisicelo esithile, iinkqubo zombane zinokukhuseleka kwaye zigcinwe ngokufanelekileyo ukuze zisebenze kakuhle.
