I-MCB (I-Miniature Circuit Breaker): Ukuphucula uKhuseleko loMbane ngeCandelo eliBalulekileyo
Kwihlabathi lanamhlanje elihambele phambili kwezobuchwepheshe, ukukhusela iisekethe kubaluleke kakhulu.Kulaphoizaphuli zesekethe ezincinci (MCBs)yiza ekudlaleni.Ngobungakanani babo obubambeneyo kunye noluhlu olubanzi lweereyithingi zangoku, ii-MCBs zitshintshile indlela esikhusela ngayo iisekethe.Kule bhlog, siza kujonga nzulu kwiimpawu kunye nezibonelelo ze-MCBs, sigxininisa ukuba kutheni zibalulekile izinto zombane kwizicelo zokuhlala kunye nezorhwebo.
Inguquko yabaphuli beesekethe:
Ngaphambi kokufika kwee-MCBs, iifuse eziqhelekileyo zazisetyenziselwa ukukhusela iisekethe.Ngelixa iifusi zibonelela ngenqanaba lokhuseleko, nazo zinemida ethile.Ngokomzekelo, xa i-fuse "iqhuma" ngenxa yephutha okanye i-overcurrent, kufuneka itshintshwe enye entsha.Oku kunokuba ngumsebenzi ochitha ixesha, ngakumbi kwindawo yoshishino apho ixesha lokuphumla lingakhokelela ekulahlekeni kwemali.Ii-MCBs, kwelinye icala, zizixhobo ezinokusetwa kwakhona ezibonelela ngenzuzo ebalulekileyo ngaphezulu kwe-fuses.
Ubungakanani obubambeneyo:
Enye yeempawu eziphawulekayo ze-MCB bubukhulu bayo obudibeneyo.Ngokungafaniyo nezaphuli zesekethe ezinkulu zexesha elidlulileyo, ii-MCBs zithatha indawo encinci kwiipaneli zombane.Oku kubumbana kuvumela ukusetyenziswa ngokufanelekileyo kwendawo, oko kuyenza ilungele ukulungisa ngokutsha iinkqubo zombane ezikhoyo kunye nofakelo olutsha.Ubungakanani babo obuncinci bukwanceda ukwenza lula ukugcinwa kunye nokuqinisekisa ukutshintshwa okulula, ukunciphisa ixesha lokuphumla.
Uluhlu olubanzi lwemisinga ekalisiweyo:
IiMCBs ziyafumaneka kwiireyithingi ezahlukeneyo zangoku ukuze zihambelane nezicelo ezahlukeneyo.Nokuba sisakhiwo sokuhlala okanye sorhwebo, ii-MCBs zibonelela ngokuguquguquka ngokunikezela ngeendlela ezahlukeneyo zokuhlangabezana neemfuno ezithile zomthwalo wombane.Oku kuguquguquka kuqinisekisa ukhuseleko olufanelekileyo lwesekethe kumonakalo onokwenzeka kwisixhobo sombane ngenxa yokugcwala okanye iisekethe ezimfutshane.
Ukhuseleko olulungiselelweyo:
Njengoko kukhankanyiwe ngaphambili, i-MCB ibonelela ngokugqithiswa kunye nokukhuselwa kwesiphaluka esifutshane.Isici esiluncedo kwii-MCBs kukukwazi ukufumanisa ngokukhawuleza nokuphendula kwiimpazamo ezinjalo zombane.Kwimeko yomthwalo ogqithisiweyo okanye omfutshane, i-breaker circuit encinci ihamba ngokukhawuleza, ukunqumla amandla kunye nokukhusela izixhobo ezisezantsi.Le mpendulo ekhawulezayo ayithinteli kuphela umonakalo kwizixhobo zombane, kodwa inciphisa ingozi yomlilo kunye neengozi zombane.
Ukhuseleko olomeleziweyo:
Xa kuziwa kwiinkqubo zombane, ukhuseleko luphambili oluphambili.Ii-MCBs zandisa ukhuseleko ngokudibanisa iimpawu ezongezelelweyo ezifana ne-built-in-arc fault monitor kunye nokukhusela umhlaba.Ezi mpawu ziqinisekisa ukubonwa kwangaphambili kweempazamo ze-arc kunye neziphene zomhlaba, ukunciphisa ngakumbi umngcipheko weengozi zombane.Nge-MCB, ungaphumla ngokulula ukwazi ukuba iisekethe zakho zikhuselwe kakuhle.
ukuququmbela:
Ukufika kwe-miniature circuit breaker (MCB) iguqule indlela esikhusela ngayo iisekethe zombane.Ubungakanani babo obuncinci, uluhlu olubanzi lokulinganiswa kwangoku kunye nokukhuselwa okuphuculweyo kubenza ukuba babe ngamacandelo abalulekileyo ombane kwizicelo zokuhlala kunye nezorhwebo.Ukubandakanya ii-MCBs kwiinkqubo zombane aziphuculi kuphela ukhuseleko, kodwa kuqinisekisa ukusebenza kakuhle kunye nokunciphisa ixesha lokuphumla.Yamkela inkqubela phambili yetekhnoloji ezizisa ii-MCBs ukukhusela iisekethe zakho ngokuzithemba.
