Ukubaluleka kwee-residual current breakers kwiinkqubo zombane
Kwihlabathi lanamhlanje eliphucukileyo nelanamhlanje, ukhuseleko lombane kufuneka lube yeyona nto iphambili kwizakhiwo zokuhlala nezezorhwebo. Njengoko izixhobo kunye neenkqubo zisetyenziswa ngakumbi nangakumbi, umngcipheko weengozi zombane kunye nemililo uyanda. Kulapho iiResidual Current Circuit Breakers (RCCB) zidlala khona indima ebalulekileyo ekuboneleleni ngokhuseleko nokuqinisekisa ukhuseleko lokufakelwa kombane.
I-RCCB, ekwaziwa ngokuba yi-isixhobo sangoku esisele (RCD), sisixhobo sokhuseleko lombane esenzelwe ukunqumla umbane ngokukhawuleza xa kufunyaniswa ukungalingani kwindlela esebenza ngayo i-current flow. Oku kungalingani kunokubangelwa ziintambo ezingasebenzi kakuhle okanye ukuvuza okuvela kunxibelelwano lomntu neengcingo eziphilayo okanye izixhobo ezingasebenzi kakuhle. Ngokufumanisa nokuqhawula umbane ngesiqingatha somzuzwana, ii-RCCB zinceda ekuthinteleni ukucima umbane, ukucima umbane kunye nemililo yombane.
Enye yezona nzuzo ziphambili zokufakelaIi-RCCBkwiinkqubo zombane kukho amandla okubonelela ngokhuseleko ekudibaneni ngokuthe ngqo nangokungathanga ngqo nezixhobo eziphilayo. Oku kuthetha ukuba nokuba umntu udibana ngengozi nocingo oluphilayo, i-RCCB iya kuphazamisa ngokukhawuleza ukuhamba kombane, ithintele ukwenzakala okanye ukufa okukhulu. Ukongeza, ii-RCCB zinokubona kwaye zithintele iimpazamo zokufakelwa kombane, ziqinisekise ukuba ukufakelwa kombane kukhuselekile kwaye kuyahambelana nemigaqo efunekayo.
Enye into ebalulekileyo kwii-RCCB kukukwazi kwazo ukubonelela ngokhuseleko kwimisinga eseleyo enokuvela ngenxa yokusilela kwezixhobo, iziphene zentambo okanye izinto ezingqongileyo ezifana nokufuma. Le misinga eseleyo inokubangela iingozi ezinkulu, ngakumbi kwiindawo ezimanzi okanye ezingaphandle, kwaye i-RCCB yenzelwe ukubona nokuqhawula umbane kwiimeko ezinjalo, ngaloo ndlela inciphisa umngcipheko wokutshayiswa ngumbane nomlilo.
Ukongeza ekuphuculeni ukhuseleko lombane, ii-RCCB zikwadlala indima ebalulekileyo ekunciphiseni umngcipheko womlilo kwizakhiwo. Imililo yombane inokubangelwa zizinto ezahlukeneyo, kubandakanya ii-short circuits, ukugqithisa kakhulu, kunye neempazamo zomhlaba. Ngokuzihlukanisa ngokukhawuleza ii-circuits okanye izixhobo ezineengxaki, ii-RCCB zinokunciphisa amathuba okuba umlilo uvele, ngaloo ndlela zikhusele ubomi kunye nepropathi.
Kubalulekile ukuqaphela ukuba kumazwe amaninzi nakwiindawo, ukufakwa kwee-RCCB kwiinkqubo zamandla kuyimfuneko esemthethweni. Ngokulandela le migaqo nemigangatho, abanini bezakhiwo kunye nabaphathi bombane banokuqinisekisa ukhuseleko kunye nokhuseleko lwabantu abasebenzisa ukufakelwa kombane.
Ngamafutshane, iziphuli-mbane ezivuzayo emhlabeni ziyinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje. Ngokuhlala ujonga umbane ngokuqhubekayo kwaye ukhawuleze ukucima umbane xa kukho ukungalingani okanye impazamo, ii-RCCB zibonelela ngomgangatho obalulekileyo wokhuseleko ngokuchasene nokutshayiswa kombane, ukutshayiswa ngumbane, kunye nemililo yombane. Ke ngoko, abanini, abakhi bombane kunye nabantu ngabanye kufuneka baqonde ukubaluleka kwe-RCCB kwaye baqinisekise ukuba ikhona kuzo zonke izinto ezifakelweyo zombane. Kaloku, xa kufikwa kukhuseleko lombane, ukuthintela kusoloko kungcono kunokujongana nemiphumo yengozi okanye umlilo.
