Yintoni iMolded Case Circuit Breaker

Ehlabathini leenkqubo zombane kunye neesekethe, ukhuseleko lubaluleke kakhulu.Esinye isixhobo esibalulekileyo esidlala indima ebalulekileyo ekugcineni ukhuselekoI-Molded Case Circuit Breaker (MCCB).Eyenzelwe ukukhusela iisekethe ekugqithiseni okanye kwiisekethe ezimfutshane, esi sixhobo sokhuseleko sidlala indima ebalulekileyo ekuthinteleni umonakalo kwiinkqubo zombane.

Ke, yintoni kanye kanye i-mold case circuit breaker?Eyaziwa ngokuba yi-MCCB, sisixhobo sokukhusela isiphaluka esizenzekelayo esisetyenziswa kwiinkqubo zombini eziphantsi kunye ne-high-voltage.Umsebenzi wayo ophambili kukuqhawula umbane ngokuzenzekelayo xa impazamo okanye i-overcurrent condition ifunyenwe.Esi senzo sikhawulezayo sinceda ukuthintela nawuphi na umonakalo okanye iimeko ezinobungozi ezinokubangelwa sisiphene sombane.

Ii-MCCBsngamacandelo abalulekileyo kuluhlu olubanzi lwezicelo ukusuka kwimizi-mveliso kunye nezorhwebo ukuya kwindawo yokuhlala.Ngokuqhelekileyo zisetyenziswa kwiinkqubo zokuhambisa amandla, amaziko okulawula iimoto kunye neebhodi zokutshintsha.Ukuguquguquka kwabo kuvumela ukuba banikeze ukhuseleko kwiindidi ezahlukeneyo zeesekethe, okwenza kube yinxalenye yokhuseleko lombane.

Enye yeenzuzo eziphambili zee-MCCBs kukukwazi kwabo ukuphatha imisinga ephezulu.Xa i-overload okanye isiphaluka esifutshane senzeke, i-MCCB iphazamisa ngokukhawuleza ukuhamba kwangoku, ukukhusela izixhobo zombane ezixhunyiwe kunye nokuthintela nawuphi na umonakalo onokwenzeka.Olu phawu aluncedi kuphela ukukhusela inkqubo yombane kodwa lukhusela naziphi na iingozi zomlilo ezibangelwa ukushisa okugqithiseleyo okubangelwa iimeko ezigqithisileyo.

Ukongeza, ii-MCCBs zilula ukusebenza kunye nokugcina.Emva kokuba iphoso licinyiwe, i-MCCB inokubuyiselwa ngokulula ukubuyisela amandla kwinkqubo ngaphandle kokungenelela ngesandla.Olu lula alugcini nje ixesha kodwa luqinisekisa ukuphendula ngokukhawuleza kuzo naziphi na iimpazamo zombane, ukunciphisa ixesha lokunciphisa kunye nokugcina ukusebenza okuqhubekayo kwenkqubo yombane.

Enye inkalo ebalulekileyo ye-MCCB kukuthembeka kwayo.Ezi zixhobo zenzelwe ukubonelela ngokhuseleko oluhambelanayo kunye noluqilima kwiimpazamo zombane ekuhambeni kwexesha.Ukukwazi kwabo ukuphatha uluhlu olubanzi lwemithwalo yombane kunye neemeko zokusingqongileyo kwenza ukuba kube yinto ethembekileyo yokuqinisekisa ukhuseleko lwesekethe kunye nokuthembeka.

Isishwankathelo,I-Molded Case Circuit Breakers (MCCBs) zibalulekile ekuqinisekiseni ukhuseleko nokhuseleko lweesekethe.Ukukwazi kwabo ukuphendula ngokukhawuleza kwi-overload okanye iimeko zesekethe ezimfutshane, kunye nokuthembeka kwabo kunye nokulula ukusebenza, kubenza babe yinto eyimfuneko kuyo nayiphi na inkqubo yombane.Kungakhathaliseki ukuba kumashishini, ukuthengisa okanye indawo yokuhlala, i-MCCBs idlala indima ebalulekileyo ekuthinteleni umonakalo kwizixhobo zombane, ukunciphisa ixesha lokunciphisa kwaye kubaluleke kakhulu, ukukhusela ubomi.Ukubaluleka kwe-MCCBs kukhuseleko lombane akunakugqithiswa ngenxa yokukwazi ukubonelela ngokhuseleko olusebenzayo kunye noluqilima lwesekethe.
