Umahluko kunye nokusetyenziswa kwe-RCCB kunye ne-RCBO

UkuqondaIi-RCCBkwayeIi-RCBOIzinto ezibalulekileyo zoKhuseleko loMbane

Ukhuseleko lubaluleke kakhulu ekufakweni kombane. IiResidual current breakers (RCCBs) kunye neeResidual current current breakers ezine-overcurrent protection (RCBOs) zizixhobo ezimbini ezibalulekileyo ezidlala indima ebalulekileyo ekukhuseleni abantu kunye nepropathi. Nangona ukusetyenziswa kwazo kufana, ukuqonda umahluko kunye nokusetyenziswa kweeRCCB kunye neeRCBO kubalulekile kuye nabani na osebenza kwindawo yombane okanye yokhuseleko.

Yintoni i-RCCB?

I-residual current breaker (RCCB) sisixhobo sokhuseleko esenzelwe ukuthintela ukutshayiswa kombane kunye nemililo yombane ebangelwa ziziphene zomhlaba. Sisebenza ngokujonga ibhalansi yombane ohamba kwiintambo ezishushu nezingathathi cala. Ukuba kufunyenwe ukungalingani kombane (umzekelo, ukuba umntu uchukumisa ucingo olushushu, olunokubonisa ukuvuza kombane), i-RCCB iyawa ngaphakathi kwee-milliseconds kwaye iqhawule isekethe. Le mpendulo ikhawulezayo ibalulekile ekuthinteleni ukwenzakala okanye ukufa okukhulu.

IiResidual current circuit breakers (RCCBs) zihlala zilinganiswa ngee-milliamperes (mA) kwaye ziyafumaneka kumanqanaba ahlukeneyo obuthathaka, njenge-30mA yokuzikhusela komntu kunye ne-100mA okanye i-300mA yokukhusela umlilo. Zisetyenziswa kakhulu kwiinkqubo zombane zokuhlala kunye nezorhwebo ukuphucula ukhuseleko, ngakumbi kwiindawo ezinamanzi, njengezindlu zangasese kunye neekhitshi.

Yintoni i-RCBO?

I-RCBO (iResidual Current Circuit Breaker ene-Overcurrent Protection) idibanisa ukusebenza kwe-RCCB kunye ne-miniature circuit breaker (MCB). Oku kuthetha ukuba i-RCBO ayikhuseli nje kuphela kwiimpazamo zomhlaba, kodwa ikwabonelela ngokhuseleko lwe-overcurrent kwi-overloads kunye ne-short circuits.

Ukusebenza okumbaxa kwe-RCBO kwenza ukuba ibe lukhetho oluguquguqukayo kwiifektri zombane zanamhlanje. Ingasetyenziselwa ukukhusela iisekethe ngazinye, ivumela ulawulo oluchanekileyo kunye nokhuseleko. Umzekelo, ukuba kwenzeka impazamo kwisekethe, i-RCBO iya kukhubeka, ihlukanise loo sekethe ngaphandle kokuchaphazela ezinye iisekethe. Olu phawu luluncedo ngakumbi kwiindawo zokuhlala ezineesekethe ezininzi.

Umahluko omkhulu phakathi kwe-RCCB kunye ne-RCBO

Nangona zombini ii-RCCB kunye nee-RCBO zibalulekile kukhuseleko lombane, usetyenziso lwazo lwahlukile kakhulu:

1. Umsebenzi: I-RCCB ibonelela ngokhuseleko lwempazamo yomhlaba kuphela, ngelixa i-RCBO ibonelela ngokhuseleko lwempazamo yomhlaba kunye nokhuseleko olugqithisileyo.

2.Ukusetyenziswa: Ii-RCCB zihlala zisetyenziswa kunye nee-MCB, ngelixa ii-RCBO zinokutshintsha zombini izixhobo, ngaloo ndlela zenza lula inkqubo yokukhusela isekethe.

3. Ixabiso kunye nendawo: Ekubeni ii-RCBO zinemisebenzi emibini, zinokuba zibiza kakhulu kunee-RCCB. Nangona kunjalo, ekubeni ii-RCBO zidityaniswe izixhobo ezibini zibe yinto enye, zinokonga indawo kwikhabhathi yokuhambisa.

4. Indlela Yokuhamba: I-RCCB iyahamba xa kufunyenwe ukungalingani kwangoku, ngelixa i-RCBO iyahamba xa kuvela ingxaki yomhlaba kunye nomsinga ogqithisileyo.

Kufuphi

Ngamafutshane, zombini ii-RCCB kunye nee-RCBO zizinto ezibalulekileyo ekuqinisekiseni ukhuseleko lombane. Ii-RCCB zikhusela kakhulu kwiimpazamo zomhlaba, nto leyo ezenza zibe zizixhobo ezibalulekileyo kwiindawo ezinobungozi obukhulu. Kwelinye icala, ii-RCBO zidibanisa ukhuseleko lweempazamo zomhlaba kunye nokhuseleko olugqithisileyo, nto leyo ebonelela ngesisombululo esibanzi kwiinkqubo zombane zanamhlanje.

Xa uyila okanye uphucula izixhobo zombane, kubalulekile ukuqwalasela iimfuno ezithile zokusingqongileyo kunye nenqanaba lokhuseleko elifunekayo. Ukuqonda umahluko kunye nokusetyenziswa kweeRCCB kunye neeRCBO kunokunceda iingcali zombane kunye nabanini bezindlu ukuba benze izigqibo ezinolwazi eziphucula ukhuseleko kunye nokuthembeka kweenkqubo zabo zombane. Nokuba ukhetha iRCCB okanye iRCBO, ukubeka phambili ukhuseleko lombane kusoloko kuyindlela efanelekileyo.
