Ukukhusela igobolondo kunye neendawo zokusebenza ze-MCCB

Abaphuli beesekethe zetyala elibunjiweyo (I-MCCB) ziyinxalenye ebalulekileyo kuyo nayiphi na inkqubo yombane, zibonelela ngokhuseleko lokugqithisa kunye nokhuseleko lwe-short-circuit. Ezi circuit breakers zenziwe ngamacandelo aliqela abalulekileyo afana ne-insulation housing kunye nendlela yokusebenza, edlala indima ebalulekileyo ekusebenzeni nasekuthembekeni kwe-molded case circuit breaker.

Indlu yokukhusela ubushushu yeyona nto iphambili kwi-molded case circuit breaker kwaye inika indawo efunekayo yokufakela zonke izinto ze-circuit breaker. Yenziwe nge-thermoset composite resin ekumgangatho ophezulu (i-DMC bulk material) okanye i-glass polyester (injection molding), eqinisekisa amandla aphezulu e-dielectric kuyilo oluncinci. Izixhobo ezithile ezisetyenziselwa i-insulating housing zimiselwa luhlobo kunye nobukhulu bendlu e-molded kwaye zichaza neempawu eziphambili ze-circuit breaker, ezifana ne-voltage ephezulu kunye ne-current rating.

Ukongeza ekuboneleleni ngendawo efunekayo yokufakela izinto, iqokobhe lokukhusela likwadlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kwe-molded case circuit breaker. Amandla aphezulu e-dielectric eqokobhe lokukhusela aqinisekisa ukuba i-circuit breaker inokusebenza ngokufanelekileyo phantsi kweemeko ezahlukeneyo zomthwalo wamandla, nto leyo ebonelela ngokhuseleko kwinkqubo yamandla kunye nabasebenzisi. Eli candelo libalulekileyo lingqina loyilo kunye nobunjineli obugqwesileyo be-molded case circuit breaker, ukuqinisekisa ukusebenza kwayo kwiintlobo ngeentlobo zezicelo.

Indlela yokusebenza ye-molded case circuit breaker yenye into ebalulekileyo ekufanele iqwalaselwe. Indlela yokusebenza inoxanduva lokuvula nokuvala oonxibelelwano ngaphakathi kwe-circuit breaker kwaye yenzelwe ukubonelela ngolawulo oluchanekileyo lokusebenza kwe-circuit breaker. Isantya apho oonxibelelwano bevula kwaye bevala ngaso sinxulumene ngokuthe ngqo nokuhamba kwesiphatho sendlela yokusebenza, okuvumela i-MCCB ukuba isebenze ngokufanelekileyo nangokuthembekileyo.

Ngokuphathelele ukhuseleko kunye nokulula, indlela yokusebenza ye-molded case circuit breaker ikwabonelela ngemisebenzi exabisekileyo. Umzekelo, ii-circuit breakers zenzelwe ukukhubeka ngokuzenzekelayo xa kuyimfuneko, ukuqinisekisa ukhuseleko lwenkqubo yombane kunye nabasebenzisi bayo. Ukongeza, xa kufakwa ii-circuit breakers ezininzi kwi-switchboard, iindawo ezahlukeneyo zesibambo zingasetyenziselwa ukuchonga ii-circuit ezineengxaki, okuvumela ukusombulula iingxaki kunye nokugcinwa ngokukhawuleza nangokufanelekileyo.

Ngaphambi kokuba baphume kwifektri, ii-molded case circuit breakers zenza uvavanyo oluqatha ukuqinisekisa ukuba ziyahlangabezana nemigangatho ephezulu yokusebenza kunye nomgangatho ophezulu. Oku kuquka ukuvavanya ii-circuit breakers ukuze zivuleke kwaye zivale phantsi koxinzelelo olukhulu kunye neemeko ze-short circuit kusetyenziswa iindlela zesigaba esinye kunye nesigaba esibini. Ngokujonga ukuba i-circuit breaker ikhubeka ngaphakathi koluhlu olumiselweyo lwamaxabiso, abavelisi banokuqinisekisa ukuba ii-molded case circuit breakers zisetyenziswa ngokukhuselekileyo nangokuthembekileyo kwiindawo ezahlukeneyo.

Ngamafutshane, igobolondo lokukhusela kunye nendlela yokusebenza ye-molded case circuit breaker zizinto ezibalulekileyo ezimisela ukusebenza kwayo, ukuthembeka kunye nokhuseleko. Ngokusebenzisa izixhobo ezikumgangatho ophezulu kunye nobunjineli obuchanekileyo, ezi zinto ziqinisekisa ukuba i-MCCB inika ukhuseleko olufanelekileyo kwinkqubo yombane ngelixa ibonelela ngokusebenza okulula nokulula ukuyisebenzisa. Ngokugxila kakhulu ekusebenzeni nasekukhuselekeni, i-molded case circuit breakers zihlala zizinto ezibalulekileyo kwizicelo eziqala kwiindawo zokuhlala ukuya kwizakhiwo zoshishino.

Iqela leMutai linamava angaphezu kweminyaka elishumi okuvelisa nokuthengisa kwicandelo le-iziphuli zesekethe, izixhobo zoqhagamshelwano, amandla amabiniiiswitshi zokudlulisela ngokuzenzekelayo, njl. Silangazelela ngokwenene ithuba lokusebenzisana nani.
