Umbane ngumthombo wamandla obalulekileyo kwimisebenzi yethu yemihla ngemihla. Nangona kunjalo, ukongeza kwiingenelo zawo, unokuba neengozi ezinkulu ukuba awuphathwanga kakuhle. Yiyo loo nto ukuba nee-circuit breakers ezithembekileyo kubalulekile ekugcineni iinkqubo zethu zombane zikhuselekile. I-miniature circuit breaker (I-MCB) sesinye sezixhobo ezinjalo ezisetyenziswa kakhulu kubunjineli bombane namhlanje. Kweli nqaku, siza kujonga ingcamango ye-MCB size sihlolisise iimpawu zayo, amandla ayo kunye neenzuzo zayo.
Yintoni iI-Miniature Circuit Breaker(MCB)?
I-miniature circuit breaker, njengoko igama lisitsho, yi-miniature circuit breaker esetyenziselwa ukukhusela ii-electrical circuits kwi-overloads kunye ne-short circuits.Ii-MCBzihlala zisetyenziswa kwizicelo zevolthi ephantsi apho i-fault currents incinci.
Ndingenza njaniiziphuli zesekethe ezincinciumsebenzi?
Ii-MCB zenzelwe ukubona iimpazamo kwiisekethe zombane kunye nokuphazamisa ukuhamba kombane xa kufunyenwe impazamo. Umgaqo wayo osebenzayo yimpembelelo ye-electromagnetic yombane. Ngexesha lokusebenza okuqhelekileyo, umbane uhamba ngoqhagamshelwano olushukumayo oluqhagamshelwe kwi-bimetal. I-bimetallic strip ineentsimbi ezimbini ezinee-coefficients ezahlukeneyo zokwandisa. Xa umbane odlula kwi-strip udlula umda othile, uvelisa ubushushu kwaye i-bimetallic strip iyagoba. Eli nyathelo likhulula indlela yokuhamba, liphazamisa ukuhamba kombane, ngaloo ndlela likhusela isekethe ekonakaleni.
Iimpawu zee-miniature circuit breakers
Ubungakanani obuncinci: Ubungakanani obuncinci beI-MCByenza ukuba ilungele ukufakwa kombane okuncinci.
Kulula Ukufakela: Uyilo lwe-MCB oluyimodyuli lwenza kube lula ukuyifaka ngaphandle kwezixhobo ezikhethekileyo.
Ukuchaneka: Ii-MCB zichaneke kakhulu ekufumaneni imisinga yempazamo kuba zisabela ngoko nangoko kuyo nayiphi na i-overcurrent kwisekethe.
Umthamo ophezulu wokuqhekeza: Ii-Miniature circuit breakers zinamandla aphezulu okuqhekeza ii-short-circuit kwaye zifanelekile ukusetyenziswa kwe-low voltage.
Iingenelo zeIiMinimable Circuit Breakers
Ixabiso Eliphantsi: Ii-MCB zisebenza kakuhle kwaye zibonelela ngokhuseleko lombane oluthembekileyo kwiisekethe.
Kulula ukuyiseta kwakhona: I-MCB inokuphinda isetelwe kwakhona ngokulula emva kokubona impazamo, oko konga ixesha kunye nomgudu.
Ukukhubeka ngokukhetha: I-miniature circuit breaker inamandla okukhetha ukukhubeka, oko kukuthi, i-miniature circuit breaker ekufutshane nee-fault point trips, ngaloo ndlela inciphisa impembelelo ye-fault.
Ihlala ixesha elide: Ii-Miniature circuit breakers zisebenza ixesha elide kwaye ziyakwazi ukumelana neemeko ezinzima ukubonelela ngokhuseleko oluthembekileyo kwiinkqubo zombane.
Ukuququmbela
Ukuqukumbela, i-MCB sisixhobo esibalulekileyo esinokubonelela ngokhuseleko olusisiseko kwiisekethe. Zingabizi kakhulu, kulula ukuzifaka kwaye zifumanisa iimpazamo ngokuchanekileyo okuphezulu. Ii-MCB zikhetho lokuqala kwiizicelo ezininzi ze-voltage ephantsi ngenxa yobukhulu bazo obuncinci kunye nomthamo ophezulu wokuqhekeka kweesekethe ezimfutshane. Ii-MCB bezikho kangangeminyaka eliqela kwaye zihlala zitshintsha ngeempawu eziphambili kunye nokugqwesa kobugcisa. Ke ngoko, ukukhetha i-MCB efanelekileyo kwinkqubo yakho yombane kubalulekile ekugcineni ukhuseleko, ukuthembeka kunye nokusebenza kakuhle.
