Ukuqonda ukubaluleka kwe-RCD Earth leakage circuit breaker

Emhlabeni wokuphepha kukagesi, izinqamuli zesekethe eziyinsalela ye-RCD zidlala indima ebalulekile ekuvikeleni abantu nempahla ezingozini zikagesi. Lawa madivayisi aklanyelwe ukuqapha ukugeleza kwamanje kumakhebuli aphilayo naphakathi nendawo, futhi uma kukhona ukungalingani, azokhubeka futhi anqamule ukunikezwa kwamandla. Esinye isibonelo esinjalo yi-I-JCR4-125 RCD, eyaziwa ngokwethembeka nokusebenza kahle ekuvimbeleni izingozi zikagesi.

II-JCR4-125 RCDikala ukugeleza kwamanje kuzintambo ezibukhoma nezingathathi hlangothi, futhi uma kukhona ukungalingani, lokho okwamanje kugeleza emhlabeni ngaphezu kokuzwela kwe-RCD, i-RCD izokhubeka futhi inqamule ukunikezwa. Lesi sici sibalulekile ekuvimbeleni ukushaqeka kukagesi nemililo ebangelwa izinto ezisebenza kabi, izintambo ezilimele, noma okunye ukungasebenzi kahle kukagesi. Ngokubona ngokushesha nokuphazamisa imisinga engavamile, ama-RCD anikeza ungqimba olwengeziwe lwesivikelo ezingozini zikagesi, okuwenza abe ingxenye ebalulekile yanoma yiluphi uhlelo lukagesi.

Enye yezinzuzo ezibalulekile zama-RCD yikhono lawo lokuvimbela ukushaqeka kukagesi. Uma umuntu ehlangana nokhondatha kagesi ophilayo, umsinga ogeleza emzimbeni wakhe ungabangela ukulimala okubi kakhulu noma ngisho nokufa. Ama-RCD aklanyelwe ngokukhethekile ukuthola ama-curls anjalo angajwayelekile futhi anqamule ukunikezwa kwamandla ngaphakathi kwama-millisecond, ehlisa kakhulu ingozi yokushaqeka kukagesi. Lokhu kubaluleke kakhulu ezindaweni lapho izinto zikagesi zisetshenziswa eduze namanzi, njengezindlu zangasese, amakhishi nezindawo zangaphandle.

Ngaphezu kokuvikela ngokumelene nokushaqeka kukagesi, ama-RCD nawo adlala indima ebalulekile ekuvimbeleni imililo kagesi. Uma kwenzeka kuba namaphutha kagesi, njengesekhethi emfishane noma ukuhluleka kokushisa, ama-currents angavamile angageleza kuzintambo, okuholela ekwakhekeni kokushisa okudlulele kanye nethuba lomlilo ovuthayo. Ngokuthola le misinga engavamile nokuvala amandla kagesi, ama-RCD asiza ekwehliseni ubungozi bomlilo kagesi, anikeze ukuthula kwengqondo okubalulekile kubanikazi bezakhiwo nabahlali.

Ngaphezu kwalokho, ama-RCD abalulekile ekuqinisekiseni ukuhambisana nemithetho nemigomo yokuphepha kukagesi. Ezindaweni eziningi, ukufakwa kwe-RCD kugunyazwe ezinhlotsheni ezithile zamasekhethi kagesi, ikakhulukazi lezo ezihlinzeka ngezindawo ezinengcuphe ephezulu yokushaqeka kukagesi noma umlilo. Kanjalo, ama-RCD awasona nje isilinganiso sokuphepha esinconyiwe kodwa ayimfuneko engokomthetho ezimweni eziningi, okuwenza abe isici esingaxoxisananga ngaso sokuklama nokufakwa kwesistimu kagesi.

Sekukonke, ama-circuit breaker amanje e-RCD asele njenge-JCR4-125 ayizingxenye ezibalulekile zokuphepha zikagesi, ezihlinzeka ngokuvikeleka okuthembekile futhi okusebenzayo ngokumelene nokushaqeka kukagesi nemililo. Kungakhathaliseki ukuthi kusezindaweni zokuhlala, ezentengiselwano, noma ezindaweni zezimboni, ama-RCD adlala indima ebalulekile ekunciphiseni ubungozi bezingozi zikagesi, ukuqinisekisa ukuthotshelwa kwemithetho, futhi ekugcineni, kuvikelwe abantu nempahla ezingozini zamasistimu kagesi angalungile. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ama-RCD ngokungangabazeki azohlala eyisivikelo esibalulekile emhlabeni wanamuhla.
