Umahluko kunye nokusetyenziswa kwe-RCCB kunye ne-RCBO

UkuqondaI-RCCBkwayeI-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 sibona ukungalingani kombane, okunokubonisa ukuvuza kombane (umzekelo, ukuba umntu uchukumisa ngengozi ucingo olushushu), i-RCCB iyawa kwi-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 lokufakelwa kombane kwanamhlanje. Ingasetyenziselwa ukukhusela iisekethe ngazinye, ivumela ulawulo oluchanekileyo kunye nokhuseleko. Umzekelo, ukuba isixhobo esithile okanye isekethe ayisebenzi kakuhle, i-RCBO iya kukhubeka, ihlukanise isiphene ngaphandle kokuchaphazela yonke inkqubo yombane. 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, zisebenza ngeenjongo ezahlukeneyo:

1. Ububanzi bokhuseleko: I-RCCB ibonelela ngokhuseleko lweziphene zomhlaba kuphela, ngelixa i-RCBO ibonelela ngokhuseleko lweziphene zomhlaba kunye nolwe-overcurrent (umthwalo omninzi kunye ne-short circuit).

2.Isicelo: I-RCCB idla ngokusetyenziswa kunye ne-MCB ukubonelela ngokhuseleko olupheleleyo, ngelixa i-RCBO ingasetyenziswa ngokuzimeleyo ukukhusela isekethe enye.

3. Ukufakelwa: Ukufakelwa kwe-RCCB kunye ne-MCB kuthatha indawo engakumbi kwibhodi yokusasaza, ngelixa i-RCBO inokudibanisa imisebenzi emibini kwisixhobo esinye, ngaloo ndlela igcina indawo.

Ukukhetha phakathi kwe-RCCB kunye ne-RCBO

Xa ukhetha phakathi kwe-RCCB kunye ne-RCBO, cinga ngeemfuno ezithile zenkqubo yakho yombane. Ukuba ufuna ukhuseleko lokusilela komhlaba kwaye sele ufake i-MCB, i-RCCB inokwanela. Nangona kunjalo, kwiindlela ezintsha zokufakela okanye zokuphucula iinkqubo ezikhoyo, ii-RCBO zihlala zicetyiswa ngenxa yeempawu zazo zokukhusela ezibanzi kunye noyilo lokonga indawo.

Kufuphi

Ngamafutshane, zombini ii-RCCB kunye nee-RCBO zizinto ezibalulekileyo kukhuseleko lombane. Ukuqonda imisebenzi yazo, umahluko, kunye nokusetyenziswa kwazo kunokukunceda wenze izigqibo ezinolwazi xa uyila okanye uphucula inkqubo yakho yombane. Nokuba ungumnikazi wendlu, umbane, okanye ingcali yokhuseleko, ukubeka phambili ukusetyenziswa kwezi zixhobo kunokunciphisa kakhulu umngcipheko weengozi zombane, kuqinisekisa imeko-bume ekhuselekileyo kuye wonke umntu.
