Isixhobo sokwaphula iisekethe esibunjiweyo: Isixhobo sokukhusela esikrelekrele kwiinkqubo zombane zoshishino

Abaphuli beeSekethe zeTyala eziBunjiweyo: Ukuqinisekisa uKhuseleko loMbane

IiMoulded Case Circuit Breakers (MCCB) zizinto ezibalulekileyo kwiinkqubo zombane ezenzelwe ukukhusela kwi-overcurrent kunye ne-short circuits. Ezi zixhobo zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokuthembeka kokufakelwa kombane kwiindawo ezahlukeneyo, kuquka iindawo zokuhlala, zorhwebo kunye nezoshishino.

Enye yeempawu eziphambili ze-MCCB kukukwazi kwayo ukubonelela ngokhuseleko lokugqithisela kunye nolwe-short-circuit. Xa umbane kwisekethe uphezulu kakhulu, i-MCCB iyakhubeka ngokuzenzekelayo, iphazamise ukuhamba kombane kwaye ithintele umonakalo kwinkqubo yombane kunye nezixhobo ezixhunyiweyo. Olu phawu lubalulekile ekuthinteleni imililo yombane kunye nezinye iingozi ezinokubangelwa ziimeko zombane ogqithisileyo.

I-MCCB ikwayilwe ukuba ibe namandla, ithembeke kwaye ikwazi ukumelana nobunzima bemisebenzi yemihla ngemihla. Ukwakhiwa kwezindlu ezibunjiweyo kubonelela ngokhuseleko oluphezulu kwizakhi zangaphakathi, kuqinisekisa ukuba i-circuit breaker inokusebenza ngokufanelekileyo kwiindawo ezinzima. Ukongeza, ii-MCCB ezininzi zenzelwe ukuba zingabi nalondolozo, nto leyo enciphisa isidingo sokuhlolwa nokugcinwa rhoqo.

I-MCCB inika ukuguquguquka kunye nokulula kokusetyenziswa ekufakweni nasekusetyenzisweni. Ezi circuit breakers zifumaneka ngobukhulu obahlukeneyo kunye noqwalaselo ukuhlangabezana neemfuno ezahlukeneyo ze-voltage kunye ne-current. Zingafakwa ngokulula kwii-switchboards nakwii-switchboards, zibonelela ngesisombululo esilula nesigcina indawo sokukhusela ii-circuit.

Ukongeza, iiMCCB zanamhlanje zihlala zineempawu eziphambili ezifana noseto lokuhamba oluhlengahlengiswayo, ukhuseleko lweziphene zomhlaba kunye nokukwazi ukujonga kude. Ezi mpawu zongezelelweyo ziphucula ukhuseleko olupheleleyo kunye nokusebenza kweenkqubo zombane, zivumela ukhuseleko olulungiselelwe wena kunye nokuphuculwa kokuchongwa kweziphene.

Ngamafutshane, ii-molded case circuit breakers ziyinxalenye ebalulekileyo yeenkqubo zombane, zibonelela ngokhuseleko olufunekayo lwe-overcurrent kunye ne-short-circuit. Ulwakhiwo lwayo oluqinileyo, ukuthembeka kunye neempawu zayo eziphambili zenza ukuba ibe yinto ephambili ekuqinisekiseni ukhuseleko lombane kunye nokuthintela iingozi ezinokubakho. Nokuba kukwiindawo zokuhlala, zorhwebo okanye kwimizi-mveliso, ii-MCCB zidlala indima ebalulekileyo ekukhuseleni ukufakwa kombane kunye nokubonelela abasebenzisi ngoxolo lwengqondo.
