Ii-residual current breaker (RCCB)iyithuluzi elibalulekile lokuphepha kagesi elidlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi ezingaba khona. Laklanyelwe ukubona nokukhipha amandla ngokuzenzakalelayo lapho kutholwa ukungalingani kwamandla kagesi, ngaleyo ndlela kuvinjelwe ukushaqeka kukagesi kanye nomlilo ongaba khona.
Umsebenzi oyinhloko weI-RCCBiwukuqapha njalo ugesi osesekethe. Iqhathanisa ugesi wokufaka nowokukhipha bese iphazamisa ugesi uma ithola umehluko omncane. Lokhu kungenzeka ngenxa yokuvuza kogesi ngenxa yezintambo ezingasebenzi kahle, izinto zikagesi ezonakele, noma ukuphazamiseka kokufakwa kokushisa. Ngokunqamula ugesi ngokushesha,Ama-RCCBukunciphisa ingozi yokushaqeka kukagesi futhi kuvimbele imililo kagesi ebangelwa izintambo ezishisa kakhulu noma ezifushane.
Enye yezinzuzo eziyinhloko ze-I-RCCByikhono layo lokubona kokubili i-DC kanye ne-AC currents. Lokhu kuyenza ifaneleke ezinhlotsheni eziningi zezicelo kusukela ekwakhiweni kwezindlu kuya ezindaweni zezimboni nezentengiselwano. Ama-RCCB avame ukufakwa emthonjeni wesekethe ukuze ahlinzeke ngesivikelo kuzo zonke izinto zikagesi ezingezansi kanye nesekethe.
Ngaphezu kokunikeza isivikelo ekushayweni ugesi kanye nomlilo,Ama-RCCBfuthi inikeza ukusebenziseka kalula. Inenkinobho yokuhlola evumela abasebenzisi ukuthi bahlole ukuthi idivayisi isebenza kahle yini ngokulingisa iphutha. Ukuhlolwa okuvamile kuyanconywa ukuqinisekisa ukuthiI-RCCBisebenza kahle futhi inikeza isivikelo esidingekayo lapho kudingeka khona.
Kubalulekile ukuqaphela ukuthi i-RCCB akufanele ididaniswe nama-circuit breaker. Nakuba womabili amadivayisi enzelwe ukuvikela amaphutha kagesi,I-RCCBigxile ekutholeni nasekuvimbeleni ukushaqeka kukagesi kanye nomlilo okubangelwa ukuvuza kwamanje.
Ngamafuphi,i-circuit breaker evuzayoiyithuluzi elibalulekile ukuqinisekisa ukuphepha kukagesi. Ngokubona nokunqamula ugesi ngokushesha uma kwenzeka ukungalingani kwamanje, ama-RCCB asiza ekuvimbeleni ukusha kukagesi okungenzeka kanye nemililo kagesi. Ukuguquguquka kwawo kanye nokulula kokusetshenziswa kwenza kube kufanelekile ezinhlotsheni ezahlukahlukene zokusetshenziswa. Ukuhlolwa njalo nokugcinwa kwama-RCCB kubalulekile ukuqinisekisa ukusebenza kwawo kahle kanye nokuvikelwa okuqhubekayo.
