Umbane ngumthombo wamandla oyimfuneko kwimisebenzi yethu yemihla ngemihla.Nangona kunjalo, ukongeza kwiingenelo zayo, inokubangela iingozi ezinkulu ukuba ayiphathwa kakuhle.Yiyo loo nto ukuba nee-breaker zesekethe ezithembekileyo kubalulekile ekugcineni iinkqubo zethu zombane zikhuselekile.Isaphuli sesekethe esincinci (MCB) sesinye isixhobo esinjalo esisetyenziswa ngokubanzi kubunjineli bombane namhlanje.Kweli nqaku, siza kungena kwingqikelelo ye-MCB kwaye sijonge iimpawu zayo, amandla, kunye nezibonelelo.
Yintoni naI-Miniature Circuit Breaker(MCB)?
I-breaker circuit encinci, njengoko igama libonisa, i-breaker circuit breaker esetyenziselwa ukukhusela iisekethe zombane kwi-overloads kunye neesekethe ezimfutshane.Ii-MCBszidla ngokusetyenziswa kwizicelo zombane ophantsi apho iimpazamo zamanzi zincinci.
Ndingenza njaniabaphuli beesekethe ezincinciumsebenzi?
Ii-MCBs zenzelwe ukufumanisa iimpazamo kwiisekethe zombane kunye nokuphazamisa ukuhamba kwangoku xa kufunyenwe impazamo.Umgaqo wayo wokusebenza yimpembelelo ye-electromagnetic yangoku yombane.Ngethuba lokusebenza okuqhelekileyo, ikhoyo ngoku ihamba ngoqhagamshelwano oluhambayo oludibaniswe ne-bimetal.I-bimetallic strip ineentsimbi ezimbini ezinee-coefficients ezahlukeneyo zokwandiswa.Xa i-current ngokusebenzisa i-strip idlula umda othile, yenza ubushushu kwaye i-bimetallic strip igobe.Esi senzo sikhupha indlela yokuhamba, iphazamisa ukuhamba kwangoku, ngaloo ndlela ikhusela isiphaluka kumonakalo.
Iimpawu zee-breaker circuits ezincinci
Ubungakanani obubambeneyo: Ubungakanani obubambeneyo beMCBiyenza ilungele ukufakelwa kombane omncinci.
Ukufakela ngokulula: Uyilo lwemodyuli ye-MCB yenza kube lula ukuyifaka ngaphandle kwezixhobo ezizodwa.
Ukuchaneka: Ii-MCBs zichanekile kakhulu ekufumaneni i-fault currents kuba ziphendula ngokukhawuleza kuyo nayiphi na i-overcurrent kwisekethe.
Umthamo ophezulu wokuqhawula: I-Miniature circuit breakers inomthamo ophezulu wokuqhawula i-short-circuit kwaye ifanelekile kwizicelo eziphantsi kwe-voltage.
Izinto ezilungileyo zeAbaphuli beSekethe abancinci
Ixabiso-Ngempumelelo: Ii-MCBs zineendleko kwaye zibonelela ngokhuseleko lombane oluthembekileyo kwiisekethe.
Ukuseta kwakhona ngokulula: I-MCB inokusetwa kwakhona ngokulula emva kokubona impazamo, ukonga ixesha kunye nomzamo.
Ukuhamba okukhethiweyo: I-breaker circuit encinci inekhono lokukhetha, oko kukuthi, i-miniature breaker circuit breaker esondeleyo kwiihambo zephutha, ngaloo ndlela inciphisa impembelelo yesiphoso.
Ukuhlala ixesha elide: Abaqhekezayo beesekethe ezincinci banobomi benkonzo ende kwaye banokumelana neendawo ezinzima ukubonelela ngokhuseleko oluthembekileyo lweenkqubo zombane.
Ukuququmbela
Ukuqukumbela, i-MCB sisixhobo esibalulekileyo esinokunika ukhuseleko olusisiseko kwiisekethe.Ziyindleko, kulula ukuzifaka kunye nokufumanisa iimpazamo ngokuchaneka okuphezulu.Ii-MCBs lukhetho lokuqala kuninzi lwezicelo zombane ophantsi ngenxa yobungakanani bazo obubambeneyo kunye nomthamo omfutshane wokuqhawula isekethe.Ii-MCBs sele zineminyaka eliqela kwaye zihlala zivela ngeempawu eziphambili kunye nokugqwesa kobugcisa.Ke ngoko, ukukhetha i-MCB efanelekileyo kwinkqubo yakho yombane kubalulekile ekugcineni ukhuseleko, ukuthembeka kunye nokusebenza kakuhle.
