I-RCD, i-RCCB, i-RCBO: Izixazululo Zokuphepha Ezithuthukisiwe Zikagesi

I-RCD, i-RCCB kanye ne-RCBO: Yazi Umehluko

Ama-RCD, ama-RCCB kanye nama-RCBO konke kuyimishini kagesi ebalulekile esetshenziselwa ukuvimbela ingozi yokushaqeka kukagesi kanye nomlilo. Nakuba kuzwakala kufana, idivayisi ngayinye inomsebenzi ohlukile futhi inezici zayo ezihlukile. Ukuqonda umehluko phakathiI-RCD, i-RCCBfuthiI-RCBOkubalulekile ekuqinisekiseni ukuphepha kukagesi ezindaweni zokuhlala nezebhizinisi.

I-RCD, isifinyezo se-Residual Current Device, iyidivayisi yokuphepha eyenzelwe ukunqamula ugesi ngokushesha lapho kutholakala ukuvuza kwamandla kusekethe. Ukuvuza kukagesi kungenzeka ngenxa yezintambo ezingalungile, ukwehluleka kwemishini, noma ukuxhumana ngqo nezingxenye eziphilayo. Ama-RCD abalulekile ekuvimbeleni ukushaqeka kukagesi futhi avame ukusetshenziswa emakhaya, emahhovisi nasezindaweni zezimboni.

I-RCCB (okungukuthi i-Residual Current Circuit Breaker) uhlobo lwe-RCD oluklanyelwe ngqo ukuvikela amaphutha omhlaba. I-RCCB iqapha ukungalingani kwamanje phakathi kwabaqhubi abaphilayo nabangathathi hlangothi futhi ikhubaza isekethe lapho kutholakala ukuvuza komhlabathi. Lokhu kwenza ama-RCCB asebenze kahle kakhulu ekuvimbeleni ukushaqeka kukagesi okubangelwa amaphutha ohlelo lukagesi.

I-RCBO (i-residual current breaker enokuvikelwa kwe-overcurrent) ihlanganisa imisebenzi ye-RCCB kanye ne-miniature circuit breaker (MCB) kudivayisi eyodwa. Ngaphezu kokunikeza ukuvikelwa kwephutha lomhlabathi, i-RCBO iphinde inikeze ukuvikelwa kwe-overcurrent, okusho ukuthi ingakhubeka isekethe uma kwenzeka i-overload noma i-short circuit. Lokhu kwenza ama-RCBO abe nezimo ezihlukahlukene futhi afaneleke ezinhlotsheni ezahlukene zezicelo, okuhlanganisa nokuvikela amasekethe ngamanye emabhodini okusabalalisa.

Omunye wemimehluko emikhulu phakathi kwala madivayisi ukusetshenziswa kwawo kanye nezinga lokuvikelwa akunikezayo. Ama-RCD avame ukusetshenziselwa ukuhlinzeka ngokuvikelwa okujwayelekile kwesekethe yonke, kuyilapho ama-RCCB nama-RCBO evame ukusetshenziselwa ukuvikela amasekethe athile noma amadivayisi ngamanye. Ngaphezu kwalokho, ama-RCBO anenzuzo eyengeziwe yokuvikelwa kokushisa ngokweqile, okwenza abe yisisombululo esiphelele samaphutha ahlukahlukene kagesi.

Uma kukhulunywa ngokufakwa, i-RCD, i-RCCB kanye ne-RCBO zenzelwe ukufakwa uchwepheshe kagesi oqeqeshiwe. Ukufakwa okufanele kubalulekile ukuqinisekisa ukuthi la madivayisi asebenza kahle futhi ahlinzeke ngokuvikeleka okudingekayo. Ukuhlolwa nokugcinwa njalo kubalulekile ukuqinisekisa ukuthi ama-RCD, ama-RCCB kanye nama-RCBO ayaqhubeka nokusebenza njengoba kulindelekile.

Ngamafuphi, i-RCD, i-RCCB kanye ne-RCBO ziyizingxenye ezibalulekile zezinhlelo zokuphepha kagesi, futhi ingxenye ngayinye inenhloso ethile yokuvimbela ukushaqeka kukagesi kanye nezingozi zomlilo. Ukuqonda umehluko phakathi kwala madivayisi kubalulekile ekukhetheni isivikelo esifanele sezinhlelo ezahlukene. Kungakhathaliseki ukuthi usebenzisa i-RCD yokuvikela okujwayelekile, i-RCCB yokuvikela amaphutha omhlaba, noma i-RCBO ukuhlanganisa isivikelo samaphutha omhlaba kanye nokuvikela okungaphezu kwamandla kagesi, la madivayisi adlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi ezindaweni zokuhlala nezentengiselwano.
