Isihluthulelo sokuvikela imishini kagesi kanye nokuphepha kwabasebenzi: indima kanye nokusetshenziswa kwe-RCBO

Isihloko Sebhulogi: Ukubaluleka Kwe-Ama-RCBOkwezokuphepha kukagesi

Emkhakheni wokuphepha kukagesi, kunezindlela eziningi ezahlukene zokuvikela abantu nempahla ezingozini zamaphutha kagesi. I-RCBO (i-residual current breaker enesivikelo sokulayisha ngokweqile) ingenye yalezi divayisi. Le divayisi idlala indima ebalulekile ekuvimbeleni imililo kagesi, ukushaqeka kukagesi, nezinye izimo eziyingozi. Kule bhulogi, sizoxoxa ngokubaluleka kwe-RCBO ekuphepheni kukagesi nokuthi kungani kufanele ibe yingxenye ebalulekile yanoma yiluphi uhlelo lukagesi.

Okokuqala, ama-RCBO aklanyelwe ukuthola nokunqamula ugesi ngokushesha lapho kutholwa iphutha lesifunda. Lokhu kungabangelwa ukuvikela okonakele, ukuchayeka emanzini, noma iphutha likagesi elibangela ukuvuza. I-RCBO ivikela ukuphepha komuntu siqu kanye nempahla ngokunqamula ngokushesha ukunikezwa kukagesi nokuvimbela ingozi yokushaqeka kukagesi nomlilo.

Enye inzuzo enkulu yama-RCBO yikhono lawo lokuvikela ukulayisha ngokweqile. Lokhu kusho ukuthi idivayisi ingabona futhi uma kukhona ugesi ongaphezu kwamandla esekethe, okungase kubangelwe ugesi ongaphezu kwamandla. Kulesi simo, i-RCBO izokhubeka futhi inqamule ugesi, ivimbele ukushisa ngokweqile kanye nezingozi zomlilo ezingaba khona. Lesi sici sibaluleke kakhulu ezindaweni zokuhlala nezentengiselwano lapho kusetshenziswa khona amadivayisi kagesi amaningi ngesikhathi esisodwa.

Ngaphezu kwalokho, ama-RCBO ahlinzeka ngezinga eliphezulu lokuvikela kuneziphuli zesekethe zendabuko nama-fuse. Nakuba iziphuli zesekethe nama-fuse zisebenza kahle ngokumelene nokulayisha ngokweqile nama-short circuits, azihlinzeki ngokuvikelwa kwamanje okusele. Ngakolunye uhlangothi, i-RCBO ingathola ngisho nokuvuza kwamanje okuncane okungaphansi kuka-30mA futhi ithathe isinyathelo esisheshayo sokunqamula ukunikezwa kwamandla. Lokhu kwenza ama-RCBO abe yingxenye ebalulekile yokufakwa kukagesi kwesimanje, njengoba ingozi yokwehluleka kukagesi ihlala ikhona.

Ngaphezu kwezici zawo zokuvikela, ama-RCBO kulula ukuwafaka nokunakekela. Angafakwa kabusha ezinhlelweni zikagesi ezikhona futhi adinga ukulungiswa okuncane uma esefakiwe. Lokhu kwenza kube yisisombululo esingabizi kakhulu sokuthuthukisa ukuphepha kukagesi ngaphandle kokudinga izinguquko ezinkulu engqalasizinda ekhona.

Kubalulekile ukuqaphela ukuthi ama-RCBO kufanele afakwe uchwepheshe kagesi oqeqeshiwe, njengoba ukufakwa nokuhlolwa okufanele kubalulekile ukuqinisekisa ukusebenza kwawo kahle. Kunconywa futhi ukuthi uhlole njalo i-RCBO ukuqinisekisa ukusebenza kwayo okufanele kanye nokuthembeka kwayo. Lokhu kubaluleke kakhulu ezakhiweni ezindala noma ezindaweni lapho izinhlelo zikagesi zingase zibe ngaphansi kwezimo ezinzima.

Ngamafuphi, ama-RCBO ayingxenye ebalulekile yokuqinisekisa ukuphepha kukagesi futhi kufanele abhekwe njengengxenye ebalulekile yanoma yiluphi uhlelo lukagesi. Ikhono lawo lokubona ugesi osele, ukuhlinzeka ngokuvikelwa kokudlula ngokweqile kanye nokunikeza izinga eliphezulu lokuphepha kunamadivayisi okuvikela isekethe yendabuko kwenza kube utshalomali olubalulekile ezisetshenziswayo zokuhlala, zezentengiselwano kanye nezezimboni. Ngokufaka i-RCBO ekufakweni kukagesi, singanciphisa kakhulu ingozi yezingozi zikagesi futhi sakhe indawo ephephile kuwo wonke umuntu.
