Uhlalutyo oluSebenzayo lweResidual Current Circuit Breaker RCBO

UkuqondaAbaphuli beesekethe zeRCBO ezisele zangoku: Isikhokelo Esipheleleyo

Kwicandelo lokhuseleko lombane,Ii-RCBO (iziphuli zesekethe ezisele zamandla ezinokhuselo olugqithisileyo lwamandla)zizinto ezibalulekileyo kwizixhobo zombane zanamhlanje. Zidibanisa ukusebenza kwezixhobo zangoku ezisele (ii-RCD) kunye nee-miniature circuit breakers (ii-MCB), zibonelela ngokhuseleko oluphindwe kabini kwiimpazamo zomhlaba kunye neemeko zomsinga ogqithisileyo. Eli nqaku liza kujonga imigaqo yokusebenza, iingenelo kunye nokusetyenziswa kwee-RCBO.

Yintoni i-RCBO?

Ii-RCBO zenzelwe ukukhusela iisekethe zombane kwiingozi ezimbini eziphambili: iimpazamo zomhlaba kunye nokugqithisa. Impazamo yomhlaba yenzeka xa umbane ungena emhlabeni ngendlela engalindelekanga, enokubangela ukutshayiswa kombane okanye umlilo. Kwelinye icala, ukugqithiswa kombane kwenzeka xa umbane ungena kwisekethe udlula amandla awo amiselweyo, okunokubangela ukutshisa kakhulu kunye nokonakalisa izixhobo zombane.

I-RCBO isoloko ijonga umsinga ohamba kwisekethe. Ukuba ibona ukungalingani phakathi kwee-conductors ezishushu nezingathathi cala (oko kukuthi, umsinga ovuzayo), iyakhubeka kwaye iwuqhawule umsinga. Ikwakhubeka ukuba umsinga udlula umda omiselweyo, ikhusela umsinga kuzo zombini iintlobo zeziphene.

Iimpawu eziphambili ze-RCBO

1. Ukhuseleko oluBini: Eyona nzuzo iphambili ye-RCBO kukukwazi kwayo ukubonelela ngokhuseleko lwamandla aseleyo kunye nokhuseleko lwamandla agqithisileyo kwisixhobo esinye. Oku kususa imfuneko yee-RCD kunye nee-MCB ezahlukeneyo, ngaloo ndlela kwenza inkqubo yombane ibe lula.

2. Uyilo oluNcinci: Ii-RCBO ngokubanzi zincinci ngakumbi kunezixhobo ezahlukeneyo, nto leyo evumela ukusetyenziswa kakuhle kwendawo kwiiyunithi zabathengi okanye kwiibhodi zokusasaza.

3. Ukukhetha Ukukhetha: Ii-RCBO ezininzi zenzelwe ukuba zikhethe ukukhubeka, nto leyo ethetha ukuba xa kukho impazamo, yisekethe echaphazelekayo kuphela eya kuqhawulwa. Olu phawu luphucula ukuthembeka kwenkqubo yombane kwaye lunciphisa ukuphazamiseka kwezinye iisekethe.

4. Uvakalelo oluLungisekayo: Ii-RCBO zibonelela ngamanqanaba ahlukeneyo obuthathaka, adla ngokuqala kwi-30mA yokhuseleko lomntu ukuya kwi-100mA okanye i-300mA yokhuseleko lwezixhobo. Oku kuguquguquka kuvumela iskimu yokhuseleko ukuba yenziwe ngokwezifiso ngokweemfuno ezithile zofakelo.

Ukusetyenziswa kwe-RCBO

Ii-RCBO zisetyenziswa kakhulu kwiindawo zokuhlala, zorhwebo, kunye nezoshishino. Emakhaya, zihlala zifakelwa kwizixhobo zombane ukukhusela iisekethe ezinika amandla izixhobo ezibalulekileyo ezifana neefriji, oomatshini bokuhlamba iimpahla, kunye neenkqubo zokufudumeza. Kwizakhiwo zorhwebo, ii-RCBO zibalulekile ekukhuseleni izixhobo ezinobuthathaka kunye nokuqinisekisa ukhuseleko lwabasebenzi kunye nabathengi.

Kwimisebenzi yemizi-mveliso, ii-RCBO zisetyenziswa koomatshini abafuna ukhuseleko lokufaka izinto ezingafunekiyo emhlabeni kunye nokukhusela izinto ezigqithisileyo. Ukhuseleko lwabo oluthembekileyo lunceda ekuthinteleni ukungasebenzi kakuhle okubiza kakhulu kunye nomonakalo wezixhobo.

Isishwankathelo

Izixhobo zamandla ombane ezisele (ii-RCBO) zibalulekile ekuqinisekiseni ukhuseleko lombane kuzo zonke iindawo. Zidibanisa ukusebenza kwee-RCD kunye nee-MCB, zibonelela ngokhuseleko olupheleleyo lwe-ground fault kunye ne-overcurrent. Ngokhuseleko oluphindwe kabini, uyilo oluncinci, ukukhubeka okukhethiweyo, kunye nobuntununtunu obuhlengahlengiswayo, ii-RCBO zisisombululo esiguquguqukayo sokufakelwa kombane kwanamhlanje. Njengoko ukhuseleko lwenkqubo yombane luyinto ephambili, ukuqonda nokusebenzisa ii-RCBO kubalulekile ekukhuseleni ubomi kunye nepropathi. Nokuba kukwiindawo zokuhlala, zorhwebo, okanye zoshishino, ii-RCBO zibalulekile kukhuseleko lombane.
