Ukuqonda Ukubaluleka KweMcbkwayeI-RcbokuKhuseleko loMbane
Kwihlabathi lanamhlanje, sixhomekeke kakhulu kumbane phantse kuzo zonke iinkalo zobomi bethu. Ukususela ekunikezeni amandla emakhaya ethu nakwiishishini ukuya ekunikezeni amandla oomatshini bemizi-mveliso, ukuxhomekeka kwethu kumbane akunakugqithiswa. Ngenxa yesi sizathu, kufuneka sibeke ukhuseleko lombane kuqala, sithintele iingozi, kwaye siqinisekise ukusebenza kakuhle kwenkqubo yombane. Izinto ezimbini ezibalulekileyo ezidlala indima ebalulekileyo kukhuseleko lombane yiMiniature Circuit Breaker (MCB) kunye neI-Residual Current Breaker ene-Overcurrent Protection (RCBO)Kule bhlog, siza kujonga ukubaluleka kweMcb kunye neRcbo ekuqinisekiseni ukhuseleko lombane.
Okokuqala, masiqonde ukuba yintoni i-MCB kunye ne-RCBO kunye nemisebenzi yazo. Ii-MCB zizitshintshi zombane ezizenzekelayo ezenzelwe ukukhusela iisekethe kumonakalo obangelwa kukugqithisa okanye i-short circuit. Zisebenza ngokubona iimpazamo kwiinkqubo zombane kunye nokuphazamisa ukuhamba kombane ukuthintela nawuphi na umonakalo onokubakho. I-RCBO, kwelinye icala, yindibaniselwano ye-RCD (Residual Current Device) kunye ne-MCB ebonelela nge-earth fault, overload kunye ne-short circuit. Ii-RCBO zibaluleke kakhulu ekuboneleleni ngokhuseleko kwi-electrical shock kunye ne-electrocution.
Esinye sezizathu eziphambili zokuba ii-MCB kunye nee-RCBO zibaluleke kakhulu kukhuseleko lombane kukukwazi kwazo ukuthintela iingozi zombane. Ukugqithisa kunye neesekethe ezimfutshane kubeka umngcipheko omkhulu womlilo kunye nomonakalo kwizixhobo zombane. Ii-MCB zenzelwe ukuphazamisa ngokukhawuleza ukuhamba kombane xa kufunyenwe umthwalo omkhulu okanye isekethe emfutshane, ngaloo ndlela zithintela umonakalo onokubakho womlilo kunye nenkqubo yombane. Ngokufanayo, ii-RCBO zibonelela ngokhuseleko olongezelelweyo ngokuvula isekethe xa kukho impazamo yamandla aseleyo, ngaloo ndlela zinciphisa kakhulu umngcipheko wokothuka kunye nokutshayiswa ngumbane.
Ukongeza, i-MCB kunye ne-RCBO zidlala indima ebalulekileyo ekukhuseleni izixhobo zombane kunye nezixhobo. Xa kukho impazamo, i-MCB kunye ne-RCBO ziya kuyisusa ngokukhawuleza isekethe enengxaki ukuthintela umonakalo kwizixhobo zombane kunye nezixhobo. Oku akuqinisekisi nje kuphela ubomi benkonzo yezixhobo, kodwa kunciphisa nomngcipheko wokulahlekelwa yimali ngenxa yomonakalo wezixhobo.
Ukongeza ekuthinteleni iingozi zombane kunye nomonakalo wezixhobo, ii-MCB kunye nee-RCBO zinegalelo kuzinzo kunye nokuthembeka kweenkqubo zombane. Ngokuzihlukanisa iisekethe ezinengxaki kunye nokuthintela ukugqithisa, ezi zixhobo zinceda ukugcina amandla aqhubekayo kuyo yonke inkqubo. Oku kubaluleke kakhulu kwiindawo zoshishino kunye nezorhwebo, njengoko naluphi na ukuphazamiseka kwiinkqubo zombane kunokubangela ukungasebenzi kakuhle kunye nelahleko yemali.
Ngamafutshane, i-miniature circuit breaker (MCB) kunye ne-residual current current breaker (RCBO) enomsebenzi wokukhusela i-overcurrent zizinto ezibalulekileyo ukuqinisekisa ukhuseleko lombane. Amandla azo okuthintela iingozi zombane, ukukhusela izixhobo kunye nokugcina uzinzo lwenkqubo yombane kuzenza zibe zibalulekileyo kwiindawo zokuhlala kunye nezorhwebo. Ngokubeka phambili ukufakwa kunye nokugcinwa kwee-MCB kunye nee-RCBO, sinokunciphisa kakhulu umngcipheko weengozi zombane kwaye siqinisekise ukusebenza ngokukhuselekileyo nangokufanelekileyo kweenkqubo zombane.
