I-RCCB MCB: Abagcini boKhuseleko lwaMandla

UkuqondaIi-RCCB kunye nee-MCBIzinto ezibalulekileyo zoKhuseleko loMbane

Kwihlabathi lokufakelwa kombane, ukhuseleko lubaluleke kakhulu. Izinto ezimbini ezibalulekileyo ezidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lombane zii-residual current circuit breakers (RCCBs) kunye nee-miniature circuit breakers (MCBs). Ezi zixhobo zimbini zisebenza ngeenjongo ezahlukeneyo kodwa zihlala zisetyenziswa kunye ukubonelela ngokhuseleko olupheleleyo kwiimpazamo zombane. Eli nqaku lijonga ngokunzulu imisebenzi, umahluko, kunye nokubaluleka kwee-RCCB kunye nee-MCB kwiinkqubo zombane zanamhlanje.

Yintoni i-RCCB?

I-RCCB, okanye i-residual current breaker, sisixhobo sokhuseleko esenzelwe ukuthintela ukutshayiswa kombane kunye nemililo yombane ebangelwa ziziphene zomhlaba. Isebenza ngokujonga ibhalansi yombane ohamba kwiintambo eziphilayo nezingathathi cala. Phantsi kweemeko eziqhelekileyo, umbane kuzo zombini iintambo kufuneka ulingane. Nangona kunjalo, ukuba kukho isiphene, njengokuvuza okubangelwa kukusilela kokufakwa kwe-insulation okanye umntu ochukumisa umbane ophilayo, i-RCCB iyawubona lo kungalingani. Xa ibona umahluko, odla ngokuba phantsi njenge-30 mA, iyawa, inqumle umbane ngokukhawuleza.

Ii-RCCB zibalulekile kwiindawo apho umngcipheko wokothuka ngumbane uphezulu khona, njengezindlu zangasese, iikhitshi kunye nangaphandle. Zibonelela ngomgangatho obalulekileyo wokhuseleko, ngakumbi kumaqela abuthathaka anjengabantwana kunye nabantu abadala.

Yintoni i-MCB?

Ii-MCB (ii-miniature circuit breakers), kwelinye icala, zenzelwe ukukhusela iisekethe kwi-overloads kunye ne-short circuits. Ngokungafaniyo nee-RCCB, ezigxila ekuvuzeni, ii-MCB zijonga umsinga ohamba kwisekethe. Ukuba umsinga udlula umthamo olinganisiweyo we-MCB ngenxa yokugcwala kakhulu (umzekelo, izixhobo ezininzi kakhulu ezisetyenziswa ngexesha elinye) okanye i-short circuit (impazamo edala indlela enganyangekiyo), i-MCB iya kukhubeka ize ivule isekethe.

Ii-MCB zibalulekile ekuthinteleni ukonakala kwezixhobo kunye neentambo, kunye nokunciphisa umngcipheko wemililo yombane ngenxa yokushisa kakhulu. Zisetyenziswa rhoqo kwiiswitchboards zokuhlala kunye nezorhwebo ukuqinisekisa ukuba iisekethe zisebenza ngaphakathi kwemida ekhuselekileyo.

Umahluko omkhulu phakathi kwe-RCCB kunye ne-MCB

Nangona zombini ii-RCCB kunye nee-MCB ziyinxalenye ebalulekileyo yokhuseleko lombane, zinemisebenzi eyahlukileyo:

1. Umsebenzi: I-RCCB isetyenziselwa ukukhusela kwimpazamo yomhlaba kunye nokutshayiswa kombane, ngelixa i-MCB isetyenziselwa ukukhusela kwi-overload kunye ne-short circuit.
2. Ukusebenza: Uhambo lwe-RCCB ngenxa yokungalingani kwangoku kunye nohambo lwe-MCB ngenxa yoxinzelelo lwamandla.
3. Ukusetyenziswa: I-RCCB isetyenziswa kakhulu kwiindawo apho umngcipheko wokothuka ngombane uphezulu, ngelixa i-MCB isetyenziselwa ukukhusela iisekethe ekugqithiseni kakhulu.

Ukubaluleka kokusebenzisa zombini i-RCCB kunye ne-MCB

Ukuze kubekho ukhuseleko oluphezulu lombane, kucetyiswa ukuba i-RCCB kunye ne-MCB zidityaniswe ngolandelelwano. Olu dibaniso lubonelela ngokhuseleko olupheleleyo kwiimpazamo zomhlaba kunye nokugqithisa kweesekethe. Kwindawo yokufakelwa kombane eqhelekileyo, i-MCB iya kukhusela isekethe ekugqithiseni kakhulu, ngelixa i-RCCB iya kuqinisekisa ukuba naluphi na umbane ovuzayo uyafunyanwa kwaye uphathwa ngokukhawuleza.

Ngamafutshane, ii-RCCB kunye nee-MCB zizinto ezibalulekileyo kwiinkqubo zombane zanamhlanje, kwaye nganye idlala indima ekhethekileyo ekukhuseleni kwiingozi zombane. Ukuqonda imisebenzi kunye nomahluko wazo kubalulekile kuye nabani na obandakanyeka ekufakweni okanye ekugcinweni kombane. Ngokusebenzisa zombini ezi zixhobo, abanini bezindlu kunye namashishini banokuphucula kakhulu ukhuseleko lwabo lombane kwaye bakhusele ubomi kunye nepropathi kwiingozi zeziphene zombane.
