I-residial yesekethe yesekethe yamanje evikela kakhulu (i-RCBO), empeleni uhlobo lokuqhekeza khona umjikelezo onomsebenzi wokuvikela ukuvuza. I-RCBO inomsebenzi wokuvikelwa ekuvuzweni, ukushaqeka kukagesi, ukugcwala ngokweqile kanye nesifunda esifushane. I-RCBO ingavimbela ukwenzeka kwezingozi zikagesi futhi kube nomphumela osobala wokugwema izingozi zomlilo ezibangelwa ukuvuza ngogesi. I-RCBOS ifakwe emabhokisini ethu ajwayelekile okusabalalisa amakhaya ukuqinisekisa ukuphepha komuntu siqu. I-RCBBO uhlobo lwe-breaker oluhlanganisa ukusebenza kwe-MCB kanye ne-RCD ku-Breaker eyodwa. I-RCBOS ingangena esigxotsheni esingu-1, esingu-1 + esingathathi hlangothi, izigxobo ezimbili noma izigxobo ezi-4 kanye nesilinganiso se-amp kusuka ku-100 a noma c, i-curve a, a & 10 I-AC.
Udinga ukusebenzisa i-RCBO ngenxa yezizathu ezifanayo esincoma i-RCB - ukukusindisa kusuka ku-electrocution ngengozi futhi uvikele imililo kagesi. I-RCBO inazo zonke izimfanelo ze-RCD enomtshina ongaphezulu.
I-RCD uhlobo lomjikelezo wesifunda olungavula ngokuzenzakalelayo i-breaker uma kwenzeka kunephutha lomhlaba. Lo mphukeli wenzelwe ukuvikela ezingozini ze-electrocution ngengozi nomlilo obangelwa amaphutha omhlaba. Abasebenza ngogesi baphinde bayibiza ngokuthi i-RCD (idivaysi eyakhayo yamanje) ne-RCCB (ikhefu lokujikeleza kwamanje (okuseleyo okusele) lolu hlobo lwe-breaker luhlala lunenkinobho ye-push yokuhlola okuqhakazayo. Ungakhetha kusuka ezigxotsheni ezi-2 noma ezi-4, ukukala okuphezulu kusuka ku-25 a ku-100 a, ukhiphe ijika le-100 a, thayipha ijika b, thayipha i-a noma i-AC ne-MMA kusuka ku-30 kuye ku-100 ma.
Ngokufanelekile, kungaba ngcono ukusebenzisa lolu hlobo lwe-breaker ukuvikela imililo enengozi kanye ne-electrocution. Noma yikuphi okukhona okukhona kumuntu okubaluleke kakhulu kune-30 Ma kungashayela inhliziyo ibe yi-fibrillar ye-ventricular (noma ukuphonsa isigqi senhliziyo kuvaliwe) - imbangela evame kakhulu yokufa ngenxa yentuthuko kagesi. I-RCD iyeka okwamanje kungakapheli ama-millisecond angama-40 kuye kwangama-40 ngaphambi kokuba kushaqeke ngogesi. Ngokuphambene, abaphukile bendawo evamile efana ne-MCB / MCCB (Breaker Circuit Breaker) noma i-fuse break kuphela lapho amaamaya ejikeleza khona ngokwedlulele (kungaba yizinkulungwane zokuvuza amanje i-RCD ephendula). Ukuvuza okuncane okuvuza kwamanje ngomzimba womuntu kungakwanela ukukubulala. Noma kunjalo, kungenzeka ukuthi ngeke kukhuphule inani lamanje elinele ngokwanele nge-fuse noma ukulayisha ngokweqile i-breaker yesekethe futhi hhayi ngokushesha ngokwanele ukusindisa impilo yakho.
Umehluko omkhulu phakathi kwalaba bobabili laba baphula izifunda ukuthi i-RCBO ifakwe umtshina ongaphezulu. Ngalesi sikhathi, kungenzeka ukuthi ucabanga ukuthi kungani bemaketha lokhu ngokwahlukana uma kubonakala kungumehluko owodwa omkhulu phakathi kwabo? Kungani ungathengisi ngohlobo kuphela emakethe? Noma ngabe ukhetha ukusebenzisa i-RCBO noma i-RCD incike ngohlobo lokufaka nesabelomali. Isibonelo, lapho kunomhlaba ukuvuza ebhokisini lokusabalalisa usebenzisa wonke ama-rcbo Breakers, kuphela umqhekezi onokushintsha okungalungile ozophuma. Kodwa-ke, lolu hlobo lwezindleko zokucushwa luphakeme kunokuba usebenzisa i-RCD's. Uma isabelomali siyinkinga, ungahlela ezintathu ze-MCB ezine ngaphansi kwensiza eyodwa eyakhayo. Ungase futhi uyisebenzise ngezinhlelo ezikhethekile ezifana neJacuzzi noma ukufakwa kweThebhu Ye-Hot Tu. Lokhu kufakwa kudinga ukusebenza ngokushesha nokungaphansi kwamanje, ngokuvamile 10MA. Ekugcineni, noma ngabe yikuphi okwephukile ofuna ukukusebenzisa kuya ngokwakha kwakho inkinobho kanye nesabelomali. Kodwa-ke, uma uzokwazi ukuklama noma uthuthukise i-switchboard yakho ukuze uhlale emthethweni futhi uqinisekise ukuvikeleka kukagesi okuhle kakhulu kwempahla yemishini kanye nempilo yomuntu, qiniseka ukuthintana nochwepheshe othembekile kagesi.
I-AFDD iyithuluzi lokuthola amaphutha we-ARC futhi yakhelwe ukuthola ukuba khona kwama-arc kagesi ayingozi futhi unqamule umjikelezo othintekile. Amadivayisi okuthola amaphutha we-Arc asebenza esebenzisa ubuchwepheshe be-microprocessor ukuhlaziya ama-waveform kagesi. Babona noma yiziphi izibonakaliso ezingajwayelekile ezizosho i-arc kwisifunda. I-AFDD izoqeda ngokushesha amandla kwisiko elithintekile ngempumelelo ukuvikela umlilo. Zizwela kakhulu ama-arcs kunamadivaysi ajwayelekile wokuvikela umjikelezo onjengeMCBS & RBCOS.
