I-Residual current breaker enesivikelo sokulayisha ngokweqile: ukuqinisekisa ukuphepha kukagesi

Ama-Residual current breaker (RCBO) anokuvikelwa kokudlula ngokweqile ayizingxenye ezibalulekile ezinhlelweni zikagesi ezenzelwe ukuvikela amaphutha kagesi kanye nokugqithisa ngokweqile. Ihlanganisa imisebenzi yedivayisi yamanje eseleyo (RCD) kanye ne-miniature circuit breaker (MCB) ibe yiyunithi eyodwa, ihlinzeka ngokuvikelwa okuphelele ekuvuza kanye nokudlula kwamandla kagesi. Le divayisi entsha idlala indima ebalulekile ekuqinisekiseni ukuphepha kukagesi ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni.

Umsebenzi oyinhloko we-RCBO ukuthola ukungalingani kwamanje okubangelwa amaphutha omhlaba, njengokuthintana kwabasebenzi nama-conductor aphilayo noma imishini eyonakele. Uma kwenzeka ukungasebenzi kahle okunjalo, i-RCBO izovula isekethe ngokushesha, ivimbele ukushaqeka kanye nengozi engaba khona yokushaywa ugesi. Lesi sici sibaluleke kakhulu ezindaweni lapho imishini kagesi iseduze namanzi, njengekhishi nezindlu zangasese, njengoba inganciphisa kakhulu amathuba engozi.

Ngaphezu kokuvikela emaphutheni omhlaba, ama-RCBO avikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane. Ngokuqapha ukugeleza kwamandla kagesi, uma kutholakala amandla kagesi amaningi, isekethe ingaphazanyiswa ngokushesha, kuvinjelwe umonakalo kuzintambo zikagesi kanye nezinto zikagesi, futhi kuncishiswe ingozi yomlilo. Lokhu kusebenza okubili kwenza i-RCBO ibe yidivayisi yokuphepha ebalulekile, enikeza isivikelo esiphelele ezingozini ezahlukene zikagesi.

Enye yezinzuzo eziyinhloko ze-RCBO yikhono layo lokuhlinzeka ngokuvikelwa komuntu ngamunye kwesekethe ngayinye. Ngokungafani nama-RCD endabuko avikela yonke imishini kwisekethe eyodwa, ama-RCBO angafakwa kumasekethe athile, okuvumela ukuvikelwa okuqondiwe. Lokhu kusho ukuthi uma kwenzeka iphutha, isekethe ethintekile kuphela enqanyulwa, okunciphisa ukuphazamiseka kohlelo lonke lukagesi. Leli zinga lokunemba lizuzisa kakhulu ezindaweni zezentengiselwano nezimboni lapho ukuqhubeka kwamandla kubalulekile khona.

Ngaphezu kwalokho, ukuvikelwa kokulayisha ngokweqile okuhlanganiswe ne-RCBO kuqeda isidingo se-MCB ehlukile, okuholela ebhodini lokusabalalisa elilula kakhulu nelonga isikhala. Lokhu akugcini nje ngokunciphisa isikhathi sokufaka nezindleko, kodwa futhi kwenza kube lula ukugcinwa nokuxazulula izinkinga ngoba kunezinto ezimbalwa okufanele ziphathwe. Umklamo omncane we-RCBO uphinde wenze kube kuhle ukufakwa kabusha ezinhlelweni zikagesi ezikhona, okuhlinzeka ngendlela elula nephumelelayo yokuthuthukisa izindlela zokuphepha.

Uma ukhetha i-RCBO, kubalulekile ukucabangela izidingo ezithile zesistimu kagesi, okuhlanganisa uhlobo lwesekethe, izinga lokuzwela elidingekayo ukuze kutholakale iphutha lomhlabathi, kanye nesilinganiso esiphezulu samandla kagesi. Kubalulekile futhi ukuqinisekisa ukuthi i-RCBO ihambisana nezindinganiso zokuphepha ezifanele kanye nemithethonqubo ukuqinisekisa ukuthembeka nokusebenza kwayo.

Ngamafuphi, i-residual current current breaker enesivikelo sokulayisha ngokweqile iyithuluzi lokuphepha elibalulekile elidlala indima ebalulekile ekuvimbeleni izingozi zikagesi. Ikhono layo lokubona amaphutha omhlaba kanye nokulayisha ngokweqile, kanye nokuvikelwa kwayo kwesekethe kanye nomklamo wokonga isikhala, lenza libe yingxenye ebalulekile ekufakweni kukagesi. Ngokuhlanganisa ama-RCBO ezinhlelweni zikagesi, ingozi yokushaqeka kukagesi, umlilo, kanye nomonakalo wemishini ingancishiswa kakhulu, okuhlinzeka ngendawo ephephile yezicelo zokuhlala nezebhizinisi.
