UkuqondaI-RCCBAmasekethe Okuvikela: Umhlahlandlela Wokuphepha Kukagesi
Ezweni lamasekethe nokuphepha, ama-RCCB (ama-residual current circuit breakers) adlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi. Ukuqonda ukuthi amasekethe okuvikela e-RCCB asebenza kanjani kubalulekile ekuqinisekiseni ukuphepha kukagesi emakhaya, emahhovisi nasezindaweni zezimboni.
I-RCCB iyithuluzi elenzelwe ukunqamula ugesi ngokushesha lapho kutholakala ukuvuza kwamandla, okungase kwenzeke lapho uhlelo lukagesi lungasebenzi kahle noma lapho umuntu ethinta ucingo oluphilayo. Lokhu kunqamula ugesi ngokushesha kusiza ukuvimbela ukushaqeka kukagesi futhi kunciphisa ingozi yomlilo obangelwa yizinto zikagesi noma izintambo ezingasebenzi kahle.
Esinye sezici ezibalulekile ze-RCCB yikhono layo lokubona ukuvuza okuncane okungaphansi kuka-30mA nokuphazamisa isekethe zingakapheli ama-millisecond ambalwa. Lokhu kuzwela kubalulekile ekuvimbeleni ukushaqeka kukagesi okungaba yingozi empilweni.
Ama-RCCB avame ukusetshenziswa kanye nama-circuit breaker noma ama-fuse ukuze ahlinzeke ngesivikelo esiphelele emaphutheni kagesi. Ama-circuit breaker aklanyelwe ukuvikela ekugcwaleni ngokweqile kanye nama-short circuit, kuyilapho ama-RCCB egxile ekutholeni nasekunqamuleni amandla lapho kwenzeka ukuvuza kwamandla.
Ezindaweni zokuhlala, ama-RCCB avame ukufakwa kuphaneli kagesi eyinhloko ukuvikela wonke amasekethe endlini. Lokhu kuqinisekisa ukuthi wonke ama-socket kagesi, amasekethe okukhanyisa kanye nezinto zikagesi zivikelwe emaphutheni kagesi angaba khona.
Ezisetshenzisweni zezimboni nezentengiselwano, ama-RCCB adlala indima ebalulekile ekuqinisekiseni ukuphepha kwabasebenzi nokuvimbela isikhathi sokungasebenzi esibizayo ngenxa yezehlakalo zikagesi. Ngokufaka ukuvikelwa kwe-RCCB engqalasizinda kagesi, amabhizinisi angakha indawo yokusebenza ephephile futhi alandele imithethonqubo yokuphepha kagesi.
Kufanele kuqashelwe ukuthi imishini ye-RCCB idinga ukuhlolwa nokugcinwa njalo ukuqinisekisa ukusebenza kwayo okuvamile. Ukuhlolwa okuvamile kusiza ekuboneni noma yiziphi izinkinga ezingaba khona futhi kuqinisekisa ukuthi i-RCCB ingaphendula ngempumelelo emaphutheni kagesi.
Ngaphezu kokunikeza isivikelo ekushayweni ugesi, ama-RCCB ahlinzeka futhi ngezinga elithile lesivikelo emililweni kagesi. Ama-RCCB asiza ekunciphiseni ingozi yemililo ebangelwa amaphutha kagesi ngokunqamula ugesi ngokushesha uma kwenzeka iphutha.
Ngamafuphi, ukuqonda indima yama-RCCB kumasekethe okuvikela kubalulekile ekukhuthazeni ukuphepha kukagesi. Kungakhathaliseki ukuthi kusezindaweni zokuhlala, zezentengiselwano noma zezimboni, ama-RCCB adlala indima ebalulekile ekuvimbeleni ukushaqeka kukagesi nokunciphisa ingozi yemililo kagesi. Ngokufaka ukuvikelwa kwe-RCCB ezinhlelweni zikagesi nokuqinisekisa ukulungiswa njalo, singakha indawo ephephile futhi sinciphise izingozi ezingaba khona ezihlobene nogesi.
