UkuqondaI-RCBOIzinto Ezibalulekileyo Zokhuseleko Lombane
Kwihlabathi lokufakelwa kombane, ukhuseleko lubaluleke kakhulu. Enye yezinto ezibalulekileyo ukuqinisekisa ukhuseleko yi-residual current breaker enokhuselo olugqithisileyo, eyaziwa ngokuba yi-RCBO. Esi sixhobo sidlala indima ebalulekileyo ekukhuseleni abantu kunye nempahla kwiimpazamo zombane, nto leyo eyenza ukuba sibe yinxalenye ebalulekileyo yeenkqubo zombane zanamhlanje.
Yintoni i-RCBO?
I-RCBO yindibaniselwano yezixhobo ezimbini zokukhusela: isixhobo samandla asele (RCD) kunye ne-miniature circuit breaker (MCB). Umsebenzi ophambili we-RCD kukufumanisa iimpazamo zomhlaba, ezenzeka xa amandla ageleza emhlabeni ngendlela engalindelekanga. Iimpazamo zomhlaba zinokwenzeka ngenxa yokusilela kokufakwa kwezinto ezikhuselayo, ukufuma okanye ukudibana ngengozi neendawo eziphilayo. Xa kufunyenwe iimpazamo zomhlaba, i-RCD iyawuqhawula umjikelo ukuze kuthintelwe umngcipheko wokutshayiswa ngumbane okanye umlilo.
Kwelinye icala, ii-MCB zikhusela kwi-overcurrents ebangelwa kukugqithisa okanye ii-short circuits. I-overcurrents inokubangela ukuba iingcingo zishushu kakhulu, nto leyo enokubangela umlilo. Ngokudibanisa le misebenzi mibini, ii-RCBO zibonelela ngokhuseleko olupheleleyo, ziqinisekisa ukuba zombini iimeko ze-ground failure kunye ne-overcurrent ziyalungiswa.
Kutheni usebenzisa i-RCBO?
Kukho iingenelo ezininzi zokusebenzisa ii-RCBOs kufakelo lombane:
1. Ukhuseleko Oluphuculweyo: Eyona nzuzo iphambili ye-RCBO kukuba ibonelela ngokhuseleko olongezelelekileyo. Ngokubona iimpazamo zomhlaba kunye nombane ogqithisileyo, inokunciphisa umngcipheko wokutshayiswa ngumbane kunye nomlilo, ikhusele abantu kunye nempahla.
2. Ukhuseleko lweSekethe nganye: Ngokungafaniyo nee-RCD zemveli ezikhusela iisekethe ezininzi, ii-RCBO zinokufakwa kwisekethe enye. Oku kuthetha ukuba ukuba isekethe enye ayisebenzi, yisekethe leyo kuphela eya kuqhawuka kwaye ezinye ziya kuqhubeka nokusebenza. Oku kuluncedo ngakumbi kwindawo yokuhlala, apho iindawo ezahlukeneyo zinokuba nemithwalo yombane eyahlukileyo.
3. Ukonga indawo: I-RCBO incinci kwaye ingathatha indawo ye-RCD kunye ne-MCB kwisixhobo esinye. Oku akugcini nje ngokugcina indawo kwizixhobo zabathengi, kodwa kukwalula inkqubo yokufakelwa kwentambo kunye nokufakelwa.
4. Kulula ukuyivavanya: Uninzi lwee-RCBO zixhotyiswe ngeqhosha lokuvavanya, nto leyo evumela umsebenzisi ukuba ajonge rhoqo ukusebenza kwesixhobo. Oku kuqinisekisa ukuba indlela yokukhusela isebenza kakuhle, nto leyo ekunika uxolo lwengqondo.
Ukufakelwa kunye nokugcinwa
Ukufakelwa kwe-RCBO kufuneka kuhlale kwenziwa yingcali yombane eqeqeshiweyo ukuqinisekisa ukuthotyelwa kwemithetho kunye nemigangatho yombane yendawo. Ingcali yombane iya kuvavanya iimfuno ezithile zofakelo, kubandakanya iimfuno zomthwalo kunye nenani leesekethe ekufuneka zikhuselwe.
Emva kokufakela, ukugcinwa rhoqo kubalulekile. Abasebenzisi kufuneka bavavanye i-RCBO besebenzisa iqhosha lokuvavanya nyanga zonke ukuqinisekisa ukuba isebenza kakuhle. Ukuba isixhobo siqhuma rhoqo okanye asikwazi ukuseta kwakhona, oko kunokubonisa ingxaki efuna ingqalelo yobuchwephesha.
Kufuphi
Ngamafutshane, ii-RCBO ziyinxalenye ebalulekileyo kwiinkqubo zombane zanamhlanje, zibonelela ngokhuseleko oluphindwe kabini kwiimpazamo zomhlaba kunye nombane ogqithisileyo. Amandla azo okuphucula ukhuseleko, ukubonelela ngokhuseleko lwesekethe nganye, kunye nokonga indawo kuzenza zilungele zombini ukusetyenziswa kweendawo zokuhlala kunye nezorhwebo. Njengoko imigangatho yokhuseleko lombane iqhubeka nokutshintsha, ukubaluleka kwezixhobo ezifana nee-RCBO akunakugxininiswa kakhulu. Ngokutyala imali kwii-RCBO ezisemgangathweni kunye nokuqinisekisa ukuba zifakwe kwaye zigcinwe kakuhle, abanini bepropathi banokunciphisa kakhulu iingozi ezinxulumene neempazamo zombane, baqinisekise imeko-bume ekhuselekileyo kuye wonke umntu.
