Kwicandelo lokhuseleko lombane,ii-residual current breakers (ii-RCCB)zidlala indima ebalulekileyo ekukhuseleni abantu kunye nempahla kwiingozi zombane. Ezi zixhobo zenzelwe ukuthintela ukutshayiswa ngumbane kunye nokunciphisa umngcipheko wemililo yombane ebangelwa ziziphene zomhlaba. Eli nqaku liza kuxoxa ngomsebenzi, ukubaluleka, kunye nokusetyenziswa kwee-RCCB ngokweenkcukacha.
Yintoni i-residual current operated circuit breaker (RCCB)?
I-residual current breaker (RCCB) sisixhobo sombane esiqhawula isekethe xa sibona ukungalingani kwamandla ombane phakathi kweentambo eziphilayo (isigaba) kunye nezingathathi cala. Oku kungalingani kunokubangelwa yimpazamo, efana nomntu ochukumisa ngempazamo umqhubi ophilayo, okanye impazamo yombane ebangela ukuba amandla ombane avuza emhlabeni. I-RCCB isoloko ijonga amandla ombane kwisekethe, kwaye ukuba ibona umahluko wamandla ombane (ngesiqhelo i-30 mA yokuzikhusela), iyawa kwaye iwaqhawule amandla ombane ngaphakathi kwee-milliseconds.
Yintoni umgaqo osebenzayo we-residual current operated circuit breaker (RCCB)?
I-residual current operated circuit breaker (RCCB) isebenza ngokomgaqo we-differential current. Iqulathe i-iron core kunye nee-coil ezimbini: enye ye-live wire kunye nenye ye-neutral wire. Kwiimeko eziqhelekileyo, i-current ehamba kwii-conductors ezimbini ilingana, kwaye amasimi emagnethi aveliswa yi-coils ayarhoxisana. Nangona kunjalo, ukuba kukho i-leaking current, le balance iyaphazamiseka, nto leyo ebangela umahluko kumandla e-magnetic field. Oku kungalingani kubangela i-RCCB ukuba ikhubeke, ikhuphe i-circuit kwaye ithintele iingozi ezinokubakho.
Ukubaluleka kweeResidual Current Operated Circuit Breakers
Ukubaluleka kwee-residual current operated circuit breakers (RCCBs) akunakujongwa. Ziyindlela ebalulekileyo yokuzikhusela kwi-electrical shock, enokukhokelela ekwenzakaleni okukhulu komntu okanye ekufeni. Ngokwemigangatho yokhuseleko, izakhiwo ezininzi zokuhlala nezorhwebo, ingakumbi iindawo ezinamanzi (ezifana nezindlu zangasese kunye neekhitshi), kufuneka zixhotyiswe ngee-RCCBs. Ii-RCCBs zinokusabela ngokukhawuleza kwiimpazamo zombane, nto leyo ephucula kakhulu ukhuseleko lokufakelwa kombane.
Ukongeza, ii-residual current operated circuit breakers (RCCBs) zinceda ekuthinteleni imililo yombane. Iimpazamo zemigca, umonakalo we-insulation, okanye iimpazamo zombane zinokubangela ubushushu obugqithisileyo kunye neentlantsi, ezinokutshisa izinto ezitshayo. Ii-RCCB zinokuqhawula isekethe ngoko nangoko xa kukho impazamo, ngaloo ndlela zinciphisa umngcipheko womlilo kwaye zikhusele ubomi kunye nepropathi.
Ukusetyenziswa kweeResidual Current Operated Circuit Breakers
IiResidual current operated circuit breakers (RCCBs) zisetyenziswa kakhulu kwiindawo ezahlukeneyo, kuquka iindawo zokuhlala, ezorhwebo, nezemizi-mveliso. Kwizakhiwo zokuhlala, zihlala zifakelwa kwipaneli ephambili yokusasaza ukukhusela zonke iisekethe. Kwizakhiwo zorhwebo, iiRCCB zibalulekile ekukhuseleni izixhobo nokuqinisekisa ukhuseleko lwabasebenzi kunye nabathengi. Kwiindawo zoshishino, ingakumbi apho kusetyenziswa oomatshini abanzima, iiRCCB zibalulekile ekukhuseleni abasebenzi kwiingozi zombane.
Ngaphezu koko, ii-residual current operated circuit breakers (RCCBs) zinokudityaniswa nezinye izixhobo zokukhusela, ezifana nee-miniature circuit breakers (MCBs) kunye nee-surge protectors (SPDs), ukwenza inkqubo yokhuseleko lombane ebanzi. Olu dibaniso aluqinisekisi nje kuphela ukubhaqwa nokuphathwa kweempazamo zomhlaba kodwa lukwajongana ngempumelelo nokugqithisa kunye nokunyuka.
Yintoni ebangela ukuba i-RCD breaker ikhubeke?
Iisekethe ezigcwele kakhulu, ukungena komswakama, iingcingo ezonakeleyo, ukuvuza komhlaba, kunye nezixhobo ezingasebenzi kakuhle zezinye zezizathu eziphambili zokukhubeka kwe-RCD. Ukuqonda ezi zinto kunokukunceda uchonge kwaye ulungise le ngxaki ngokukhawuleza ukuqinisekisa ukhuseleko lombane ekhayeni lakho.
Isishwankathelo
Ngamafutshane, ii-residual current circuit breakers (ii-RCCB) ziyinxalenye ebalulekileyo yeenkqubo zokhuseleko lombane zanamhlanje. Ziyayibona kwaye ziphendule ukungalingani kombane, zisebenza njengezixhobo ezibalulekileyo zokuthintela ukuqhawuka kombane kunye nemililo yombane. Njengoko ubomi bethu bemihla ngemihla buxhomekeke ngakumbi kumbane, ukuqonda nokusebenzisa ii-RCCB kubalulekile ukuqinisekisa ukhuseleko emakhaya, kwiindawo zokusebenza, nakwezinye iindawo. Ukutyala imali kwii-RCCB ezikumgangatho ophezulu kunye nokuqinisekisa ukufakwa kwazo ngokufanelekileyo kunika uxolo lwengqondo kwaye kuthintela ngempumelelo ukuqhawuka kombane ngengozi.
