I-Residual Current Operated Circuit Breaker (RCBO) Principle and Advantages
An I-RCBOligama elishunqulelweyo leResidual Current Breaker ene-Over-current. AnI-RCBOikhusela izixhobo zombane kwiintlobo ezimbini zeempazamo; intsalela yangoku nangaphezulu.
Umsinga oshiyekileyo, okanye ukuvuza koMhlaba njengoko kunokubhekiswa kuko ngamanye amaxesha, kuxa kukho ikhefu kwisekethi enokuthi ibangelwe ziintambo zombane ezingalunganga okanye ukuba ucingo lusikwe ngempazamo. Ukuthintela ukuhanjiswa kwangoku kwaye kubangele ukothuka kombane, i-RCBO i-breaker yangoku iyakumisa oku.
I-Over-current kuxa kukho ukugcwala okubangelwa zizixhobo ezininzi ezidityanisiweyo okanye kukho isiphaluka esifutshane kwinkqubo.
Ii-RCBOszisetyenziswa njengendlela yokukhusela ukunciphisa amathuba okwenzakala kunye nobungozi kubomi bomntu kwaye yinxalenye yemimiselo ekhoyo yombane efuna ukuba iisekethe zombane zikhuselwe kwi-residual current. Oku kuthetha ukuba kwiipropati zasekhaya, i-RCD iya kusetyenziselwa ukuphumeza oku kunokuba i-RCBO njengoko ixabisa ngakumbi kodwa ukuba i-RCD ihamba, inciphisa amandla kuzo zonke ezinye iisekethe ngelixa i-RCBO isenza umsebenzi wazo zombini i-RCD. kunye ne-MCB kwaye iqinisekisa ukuba amandla ayaqhubeka ukuya kuzo zonke ezinye iisekethe ezingakhange zikhubeke. Oku kubenza baxabiseke kumashishini angenako ukuhlawula yonke inkqubo yamandla ukusika ngenxa yokuba kukho umntu olayishe kakhulu iaa socket yeplagi (umzekelo).
Ii-RCBOszenzelwe ukuqinisekisa ukusebenza okukhuselekileyo kweesekethe zombane, kubangela ukuqhawulwa ngokukhawuleza xa kukho i-residual current okanye i-over-current ifunyenwe.
Umgaqo wokusebenza weI-RCBO
I-RCBOisebenza kwi-Kircand iingcingo eziphilayo. Kuyavunywa ukuba, i-current equkuqela ukuya kwisekethe ukusuka kwintambo ephilayo kufuneka ilingane naleyo ihamba ngocingo olungathathi hlangothi.
Ukuba iphoso lenzeka, i-current evela kwintambo engathathi hlangothi iyanciphisa, kwaye umahluko phakathi kwezi zibini zibizwa ngokuba yiNdawo yokuHlala. Xa iNdawo yokuHlala ichongiwe, isixokelelwano sombane sibangela ukuba i-RCBO iphume kwisekethe.
Isiphaluka sovavanyo esibandakanyiweyo kwisixhobo sangoku esishiyekileyo siqinisekisa ukuba ukuthembeka kwe-RCBO kuyavavanywa. Emva kokuba utyhale iqhosha lokuvavanya, i-current iqala ukuhamba kwisekethe yovavanyo ukususela ekubeni yaseka ukungalingani kwikhoyili engathathi hlangothi, i-RCBO ihamba, kunye nokunikezelwa kokuqhawula kunye nokutshekisha ukuthembeka kwe-RCBO.
Yintoni inzuzo ye-RCBO?
Konke kwisixhobo esinye
Ngaphambili, iingcali zombane zifake iisaphuli sesekethe esincinci (MCB)kunye nesixhobo sangoku esishiyekileyo kwibhodi yombane. I-residual current esebenzayo i-circuit breaker yenzelwe ukukhusela umsebenzisi ekuvezweni kwimisinga eyingozi. Ngokwahlukileyo, i-MCB ikhusela i-wiring yesakhiwo ekugqithiseni.
Iibhodi zokutshitsha zinendawo encinci, kwaye ukufakela izixhobo ezibini ezahlukeneyo zokhuseleko lombane ngamanye amaxesha kuba yingxaki. Ngethamsanqa, izazinzulu ziye zaphuhlisa i-RCBOs ezinokwenza imisebenzi emibini ekukhuseleni iingcingo zesakhiwo kunye nabasebenzisi kunye nokukhulula indawo kwi-switchboard ukususela ekubeni i-RCBOs inokubuyisela izixhobo ezibini ezahlukeneyo.
Ngokubanzi, ii-RCBOs zinokufakelwa ngexesha elifutshane. Ngoko ke, ii-RCBOs zisetyenziswa ngabasebenzi bombane abafuna ukuphepha ukufaka zombini i-MCB kunye ne-RCBO breakers.
