Isiphazamisi sesekhethi esisele esinokuvikela kwamanje (i-RCBO), empeleni siwuhlobo lwesiphazamisi esinomsebenzi wokuvikela ukuvuza.I-RCBO inomsebenzi wokuvikela ekuvuzeni, ukushaqeka kukagesi, ukugcwala ngokweqile kanye nokujikeleza okufushane.I-RCBO ingavimbela ukwenzeka kwezingozi zokushaqeka kukagesi futhi ibe nomthelela osobala wokugwema izingozi zomlilo ezibangelwa ukuvuza kukagesi.Ama-RCBO afakwe emabhokisini ethu avamile okusabalalisa izindlu ukuze kuqinisekiswe ukuphepha kwabantu.I-RCBO iwuhlobo lwe-breaker ehlanganisa ukusebenza kwe-MCB ne-RCD ku-breaker eyodwa.Ama-RCBO angeza ngesigxobo esingu-1, 1 + angathathi hlangothi, izigxobo ezimbili noma izigxobo ezi-4 kanye nesilinganiso se-amp kusuka ku-6A kuye ku-100 A, ijika elikhubekayo B noma C, Umthamo wokuphuka 6K A noma 10K A, RCD uhlobo A, A & AC.
Udinga ukusebenzisa i-RCBO ngezizathu ezifanayo esincoma ngazo i-RCB - ukuze ikusindise ekubanjweni ugesi ngengozi futhi uvimbele imililo kagesi.I-RCBO inazo zonke izimfanelo ze-RCD enomtshina we-overcurrent.
I-RCD iwuhlobo lwe-circuit breaker engavula ngokuzenzakalelayo i-breaker uma kwenzeka kuba nephutha lomhlaba.Le breaker yakhelwe ukuvikela ezingozini zokushaywa ugesi ngengozi nomlilo obangelwa amaphutha omhlaba.Abasebenza ngogesi baphinde bayibize ngokuthi i-RCD (Idivayisi Yamanje Esele) kanye ne-RCCB (I-Residual Current Circuit Breaker) Lolu hlobo lwesinqamuli luhlala lunenkinobho yokuphusha yokuhlola i-breaker.Ungakhetha kuzigxobo ezi-2 noma ezi-4, ukulinganisa kwe-Amp kusuka ku-25 A kuye ku-100 A, ijika elikhubekayo B, Uhlobo A noma i-AC kanye nesilinganiso se-mA sisuka ku-30 siye ku-100 mA.
Okufanelekile, kungaba ngcono ukusebenzisa lolu hlobo lwe-breaker ukuvimbela imililo yengozi kanye nokucwiliswa kukagesi.Noma imuphi umsinga odlula kumuntu obaluleke ngaphezu kuka-30 mA ungaqhubezela inhliziyo ibe yi-fibrillation ye-ventricular (noma ilahle isigqi senhliziyo)—isizathu esivame kakhulu sokufa ngenxa yokushaqeka kukagesi.I-RCD imisa amandla amanje phakathi kwama-millisecond angama-25 kuya kwangu-40 ngaphambi kokuthi kwenzeke ukushaqeka kukagesi.Ngokuphambene, ama-circuit breaker avamile njenge-MCB/MCCB (Miniature Circuit Breaker) noma ama-fuse aphuka kuphela uma i-current kusekethe ingaphezu kwamandla (okungaba izikhathi eziyizinkulungwane lapho i-RCD iphendula khona).Ukuvuza okuncane okuhamba emzimbeni womuntu kunganele ukukubulala.Noma kunjalo, ngeke kukhuphule inani lamanje eliphelele ngokwanele ukuze kufakwe i-fuse noma kulayishe ngokweqile i-breaker circuit futhi kungasheshi ngokwanele ukusindisa impilo yakho.
Umehluko omkhulu phakathi kwawo womabili lawa ma-circuit breaker ukuthi i-RCBO ifakwe umtshina oweqile.Kuleli qophelo, ungahle ucabange ukuthi kungani bezithengisa ngokwehlukana uma kubonakala kunomehluko owodwa omkhulu phakathi kwabo?Kungani ungadayisi ngomusa kuphela emakethe?Ukuthi ukhetha ukusebenzisa i-RCBO noma i-RCD kuncike ohlotsheni lokufaka nesabelomali.Isibonelo, uma kukhona ukuvuza komhlaba ebhokisini lokusabalalisa kusetshenziswa zonke izinqamuli ze-RCBO, isinqamuli esineswishi engalungile kuphela esizocisha.Nokho, lolu hlobo lwezindleko zokumisa luphakeme kunokusebenzisa ama-RCD.Uma isabelomali siyinkinga, ungalungiselela i-MCB emithathu kwezine ngaphansi kwedivayisi eyodwa eyinsalela yamanje.Ungakwazi futhi ukuyisebenzisela izinhlelo zokusebenza ezikhethekile njenge-jacuzzi noma ukufaka ubhavu oshisayo.Lokhu kufakwa kudinga ukusebenza kwamanje okusheshayo nokuncane, ngokuvamile okungu-10mA.Ekugcineni, noma iyiphi i-breaker ofuna ukuyisebenzisa incike ekwakhiweni kwebhodi lokushintsha kanye nesabelomali.Kodwa-ke, uma uzoklama noma uthuthukise ibhodi lakho lokushintshela ukuze uhlale ulawula futhi uqinisekise ukuvikelwa kukagesi okungcono kakhulu kukho kokubili impahla yesisetshenziswa nempilo yomuntu, qiniseka ukuthi uthintana nochwepheshe kagesi onokwethenjelwa.
I-AFDD iyi-Arc Fault Detection Device futhi iklanyelwe ukuthola ukuba khona kwama-arcs kagesi ayingozi futhi inqamule isekethe ethintekile.Amadivayisi e-Arc Fault Detection asebenza esebenzisa ubuchwepheshe be-microprocessor ukuhlaziya i-waveform kagesi.Babona noma yimaphi amasignesha angajwayelekile angasho i-arc kusekethe.I-AFDD izonqamula ngokushesha amandla esekethe ethintekile ivimbele umlilo.Azwela kakhulu kuma-arcs kunamadivayisi ajwayelekile okuvikela isekethe njengama-MCB nama-RBCO.
