Kwi-MCCB, ireyithwe kwi-short circuit breaking capacity ibhekisa kumthamo wokuqhawuka phantsi kweemeko ezithile.Emva kwenkqubo yovavanyo oluchaziweyo, kuyimfuneko ukuqwalasela ukuba i-breaker circuit iyaqhubeka nokuthwala i-current yayo ehleliweyo.Ukuze kuhlangatyezwane neemfuno zabasebenzisi abahlukeneyo, abaninzi abavelisi besekethe ngoku bahlulahlula amandla okuqhekeza iqokobhe elifanayo kumanqanaba ahlukeneyo, kwaye abasebenzisi banokukhetha isaphuli sesekethe esifanelekileyo ngokweemfuno zabo ukusuka kowona mncinci ukuya kowona mkhulu. abaphuli beesekethe bangoku.Zixhaphake kakhulu kwaye zifumaneka phantse kuso nasiphi na isakhiwo okanye isakhiwo esihlala sithathwa njengesiqhelo.Nangona kunjalo, badlala indima ebalulekileyo kwinkqubo yethu yegridi yombane kwaye kufuneka igcinwe ukuze ihambisane nemigangatho yamva nje yokhuseleko.
Ii-MCCBs zibonelela ngempendulo ekhawulezileyo kwimpazamo yesiphaluka esifutshane, ngokusekwe kumgaqo we-electromagnetism.I-MCCB iqulethe ikhoyili ye-solenoid eyenza indawo encinci ye-electromagnetic xa ikhoyo ngoku idlula kwi-MCCB.I-MCCB isebenzisa isixhobo esinobuntununtunu kubushushu (isixhobo sobushushu) ngesixhobo esinovakalelo lwe-electromagnetic yangoku (isixhobo sombane) ukunika indlela yohambo (imagnethi yobushushu) kukhuseleko lobushushu kunye neenjongo zokuzahlula.Ngexesha lokusebenza okuqhelekileyo okanye iimeko eziqhelekileyo, intsimi ye-electromagnetic eyenziwa yi-solenoid coil ayinanto.Nangona kunjalo, xa impazamo yesiphaluka esifutshane isenzeka kwisekethe, umsinga omkhulu uqala ukuhamba nge-solenoid kwaye, ngenxa yoko, intsimi eyomeleleyo ye-electromagnetic isekiwe etsala ibha yohambo kwaye ivule abafowunelwa.
