I-Miniature circuit breakers (MCBs) zizinto ezibalulekileyo kwiinkqubo zombane ezenzelwe ukukhusela kwiisekethe ezingaphezulu kunye nezifutshane. Isalathiso sokuthembeka se-miniature circuit breakers yinto ephambili ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kofakelo lombane. Ukuqonda esi salathisi kubalulekile kwiinjineli zombane, amagcisa, kunye nabani na obandakanyekayo kuyilo nokugcinwa kweenkqubo zombane.
Isalathiso sokuthembeka kwe-MCB ngumlinganiselo wokukwazi kwayo ukwenza ngokungaguqukiyo ngaphakathi kweeparamitha ezichaziweyo ekuhambeni kwexesha. Ithathela ingqalelo izinto ezinje ngomgangatho wezinto eziphathekayo, uyilo, iinkqubo zokuvelisa, kunye nokuthotyelwa kwemigangatho yoshishino. Izibonakaliso eziphezulu zokuthembeka zibonisa ukuba abaphuli beesekethe ezincinci abanako ukungasebenzi okanye ukungasebenzi kakuhle ngexesha lokusebenza okuqhelekileyo, ukubonelela ngezinga eliphezulu lokukhusela iinkqubo zombane.
Izinto ezininzi eziphambili ezichaphazela isalathiso sokuthembeka kwamaqhekeza amancinci amancinci. Enye yeengcamango eziphambili ngumgangatho wezinto ezisetyenziselwa ukwakhiwa kwayo. Amacandelo aphezulu kunye nobuchule bokwakha obunqabileyo buphucula kakhulu ukuthembeka kwe-MCB. Ukongeza, ukuthobela imigangatho yoshishino kunye neenkqubo zovavanyo olungqongqo ngexesha lokuvelisa kubalulekile ekuqinisekiseni ukusebenza okufanayo.
Uyilo lwe-MCB lukwadlala indima ebalulekileyo ekumiseleni ukuthembeka komgangatho wayo. Izinto ezifana ne-tripping mechanism, izinto zoqhagamshelwano kunye neempawu ze-thermal zenzelwe ngokucophelela ukuqinisekisa ukusebenza okuthembekileyo phantsi kweemeko ezahlukeneyo zomthwalo. I-breaker circuit breaker eyilwe kakuhle iya kuba ne-index ephezulu yokuthembeka, inika ukuzithemba kwikhono layo lokukhusela isiphaluka.
Ukugcinwa rhoqo kunye nokuvavanya kubalulekile ukuvavanya ukuthembeka kwe-MCBs kwiifakelo zombane ezikhoyo. Ukuhlolwa rhoqo, ukulinganisa kunye nokuvavanya phantsi kweemeko zeempazamo ezifaniswayo kunceda ukuchonga naziphi na iingxaki ezinokuthi zibe khona kwaye uqinisekise ukuba i-miniature breaker circuit breaker iyaqhubeka nokusebenza ngaphakathi kweenkcazo ezithembekileyo zokuthembeka.
Isishwankathelo, izikhombisi ezithembekileyo zeesekethe ezincinci ziyingqwalasela ephambili ekuqinisekiseni ukhuseleko kunye nokusebenza kweenkqubo zombane. Ngokuqonda izinto ezichaphazela le index, iingcali zombane zingenza izigqibo ezinolwazi xa ukhetha, ukufaka, nokugcina ii-MCBs kwiinkqubo ezahlukeneyo. Ukubeka phambili ukuthembeka kwe-MCB ekugqibeleni kunegalelo kukhuseleko lulonke kunye nokusebenza kakuhle kofakelo lombane.
