Abaphuli beSekethe abancinci: Izixhobo ezifanelekileyo zokuKhusela uFakelo loMbane
Ukhuseleko lubalulekile kufakelo lombane.Ukusilela kwesekethe kunokubangela ukwenzakala ebantwini, kwipropathi nakwizixhobo.Ke ngoko, nasiphi na isixhobo kufuneka sibe nenkqubo yokhuseleko eyomeleleyo yokuthintela nasiphi na isiganeko esiyintlekele ukuba senzeke.Esinye sezixhobo ezibaluleke kakhulu kulo mba siqhekeza sesekethe esincinci (MCB).Kule bhlog, siza kuphonononga iimpawu, izibonelelo, kunye nokusetyenziswa kwesi sixhobo sokhuseleko sibalulekileyo.
Yintoni naI-Miniature Circuit Breaker?
A i-breaker circuit encincisisixhobo esibambeneyo nesithembekileyo esiqhawula umbane kwisekethe xa kukho imeko yombane engaqhelekanga.IMCBinamacandelo amabini asisiseko - i-bimetal kunye ne-trip mechanism.I-Thermal okanye i-electromagnetic overload kwi-bimetal sensing circuit.Xa i-current idlula umthamo olinganisiweyo we-breaker circuit, i-bimetal igoba, ibangela ukuba indlela yokukhwela isebenze.
Indlela yohambo yilatshi egcina abafowunelwa bevaliwe xa kungekho mthwalo ogqithisileyo kwisekethe.Xa i-bimetal ihamba, i-latch ikhulula abafowunelwa, isusa amandla kwisiphaluka.IMCBuqhawula umbane ngoko nangoko, ukuthintela nawuphi na umonakalo okanye iimeko ezingakhuselekanga.Ngoko ke, ii-breaker circuit encincisisixhobo esibalulekileyo sokuthintela umlilo wombane, ukutshatyalaliswa kombane kunye nesekethe emfutshane.
Iinzuzo zokusebenzisaMCB
Enye yeenzuzo eziphambili zokusebenzisa i-MCB kukuba inika ukhuseleko oluthembekileyo kwiimpazamo zombane.Ngokungafaniyo neefusi okanye nasiphi na esinye isixhobo sokukhusela,Ii-MCBszinokusetyenziswa kwakhona.Emva kokuba iphoso licinyiwe, i-MCB inokubuyiselwa kwakhona, ivumela amandla ukuba abuyiselwe kwisekethe.Ngoko ke, ii-breaker circuit encinciayifuni kutshintshwa rhoqo isixhobo sokukhusela, nto leyo egcina iindleko zokusigcina.
Enye inzuzo ebalulekileyo yokusebenzisaIi-MCBsbubungakanani bazo obubambeneyo.Njengoko itekhnoloji ihambela phambili, ii-MCBs zanamhlanje ziba ncinci ngobungakanani ukuze zithathe indawo encinci kwibhodi yokutshintsha.Ukongeza, ii-MCBs ziyafumaneka kwimisinga eyahlukeneyo elinganisiweyo kunye nokwaphulwa kwamandla, okwenza ukuba zilungele usetyenziso olubanzi.Ii-MCBs zinokukhusela uluhlu lweesekethe, ukusuka kwiisekethe ezincinci zokukhanyisa ukuya kwimithwalo enzima yemizi-mveliso.
Ukusetyenziswa kweMiniature Circuit Breakers
MCBsisixhobo esiyimfuneko kulo naluphi na ufakelo lombane.Zisetyenziswa kwizicelo zokuhlala, zorhwebo kunye nezoshishino.Kwizicelo zokuhlala, ii-MCBs zikhusela ukukhanya kunye neesekethe zamandla.Umzekelo, ii-MCBs ziyakwazi ukwahlula izixhobo ezingalunganga okanye iintambo zombane ekhitshini okanye kwigumbi lokuhlala.Kwizicelo zorhwebo, ii-MCBs zifakwe kwii-switchboards ukukhusela iikhompyuter, iiseva, kunye nezinye izixhobo zombane ezibuthathaka.Kwizicelo zamashishini, iiMCBs zisetyenziselwa ukukhusela oomatshini abanzima, iimoto kunye neminye imithwalo ephezulu yamandla.
ukuququmbela
Ukuqukumbela, abaphuli beesekethe ezincinci bayinxalenye ebalulekileyo yokufakelwa kombane.Ikhusela iinkqubo zombane kwiimeko ezingaqhelekanga zombane kwaye ikhusela nawuphi na umonakalo, ukwenzakala okanye ilahleko.Ii-MCBs zibonelela ngokhuseleko oluthembekileyo, zisebenziseka kwakhona kwaye zithatha indawo encinci kakhulu.Ke ngoko, ii-MCBs zifanelekile kuluhlu lwezicelo ukusuka kwindawo yokuhlala ukuya kwimizi-mveliso.Kuba ukhuseleko lombane lubaluleke kakhulu, kubalulekile ukukhetha i-MCB efanelekileyo kwisicelo sakho ukuqinisekisa ukhuseleko oluphezulu.
