I-RCD/RCCB/RCBO: Ukhuseleko olupheleleyo loMbane

UkuqondaI-RCD, I-RCBOkwayeI-RCCBIzixhobo zoKhuseleko loMbane eziSisiseko

Kwihlabathi lokhuseleko lombane, uya kudibana namagama anjenge-RCD, i-RCBO kunye ne-RCCB. Ezi zixhobo zidlala indima ebalulekileyo ekukhuseleni abantu kunye nempahla kwiingxaki zombane. Ukuqonda imisebenzi yazo, umahluko kunye nokusetyenziswa kwazo kubalulekile kuye nabani na obandakanyeka ekufakweni okanye ekugcinweni kombane.

Yintoni i-RCD?

I-RCD, okanye isixhobo samandla asele, sisixhobo sokhuseleko esenzelwe ukuthintela ukutshayiswa kombane kunye nemililo yombane ebangelwa ziziphene zomhlaba. Sisebenza ngokujonga rhoqo umbane ohamba kwisekethe. Ukuba sibona ukungalingani phakathi kweentambo ezishushu nezingathathi cala (okubonisa ukuba umbane uyavuza emhlabeni), sivula isekethe ngaphakathi kwee-millisecond. Le mpendulo ikhawulezayo inokusindisa ubomi, yenze ii-RCD zibe yinxalenye ebalulekileyo yeenkqubo zombane zokuhlala nezezorhwebo.

Ii-RCD zisetyenziswa kakhulu kwiisekethe ezibonelela ngezixhobo zangaphandle, amagumbi okuhlambela kunye neekhitshi apho umngcipheko wokothuka ngombane uphezulu. Ziza ngeendlela ezahlukeneyo, kuquka ii-RCD eziphathwayo zokufakelwa okwethutyana kunye nee-RCD ezisisigxina ezifakwe kwiiyunithi zabathengi.

Yintoni i-RCCB?

I-RCCB, okanye i-residual current breaker, luhlobo olukhethekileyo lwe-RCD. Umsebenzi ophambili we-RCCB kukubona iimpazamo zomhlaba nokuvula i-circuit ukuthintela ukutshayiswa ngumbane. Ngokungafaniyo ne-standard circuit breakers ezikhusela kwi-overloads kunye ne-short circuit, ii-RCCB zigxila kuphela ekukhuseleni ukuvuza komhlaba.

Ii-RCCB zisetyenziswa kakhulu kwiinkqubo zombane zokuhlala nezezorhwebo ukuphucula ukhuseleko. Zifumaneka ngokwamanqanaba ahlukeneyo, nto leyo evumela abasebenzisi ukuba bakhethe isixhobo esifanelekileyo kwiimfuno ezithile zokufakelwa kwabo umbane. Nangona ii-RCCB zibonelela ngokhuseleko olugqwesileyo kwi-electrical shock, aziboneleli ngokhuseleko kwi-overloads okanye kwi-short circuits, apho ezinye izixhobo zisebenza khona.

Yintoni i-RCBO?

I-RCBO, okanye i-residual current breaker enokhuselo olugqithisileyo, idibanisa imisebenzi ye-RCD kunye ne-circuit breaker. Oku kuthetha ukuba i-RCBO ayikhuseli kuphela kwiimpazamo zomhlaba, kodwa ikwakhusela nakwii-overloads kunye nee-short circuits. Olu sebenzi lubini lwenza i-RCBO ibe lukhetho oluguquguqukayo lokufakelwa kombane kwanamhlanje.

Ii-RCBO ziluncedo kakhulu apho indawo incinci khona, njengoko zinokuthatha indawo ye-RCD kunye ne-circuit breaker ngaxeshanye. Oku akupheleli nje ekwenzeni lula i-switchboard, kodwa kukwaphucula ukhuseleko ngokubonelela ngokhuseleko olupheleleyo kwisixhobo esinye. Zilungele iipropati zokuhlala, izakhiwo zorhwebo kunye nokusetyenziswa kwemizi-mveliso.

Umahluko oPhambili

Nangona ii-RCD, ii-RCCB kunye nee-RCBO zineenjongo ezifanayo kukhuseleko lombane, imisebenzi yazo yahlukile kakhulu:

- I-RCD: Isetyenziswa kakhulu ukubona iimpazamo zomhlaba kunye nokukhupha isekethe ukuthintela ukubetheka kombane. Ayiboneleli ngokhuseleko olugqithisileyo okanye olufutshane lwesekethe.

- I-RCCB: I-RCD eyenzelwe ngokukodwa ukubona iimpazamo zomhlaba. Njenge-RCD, ayikhuseli kwi-overloads okanye kwi-short circuits.

- I-RCBO: Idibanisa ukusebenza kwe-RCD kunye ne-circuit breaker ukukhusela kwiimpazamo zomhlaba kunye nokugqithisa/ii-short circuits.

Kufuphi

Ngamafutshane, ii-RCD, ii-RCCB, kunye nee-RCBO zizixhobo ezibalulekileyo kukhuseleko lombane. Ukuqonda imisebenzi kunye nomahluko wazo kubalulekile ekukhetheni ukhuseleko olufanelekileyo kwinkqubo yakho yombane. Nokuba ungumnikazi wendlu, umbane, okanye umphathi wesakhiwo, ukuqonda ezi zixhobo kunokukunceda wenze ukhetho olukhuselekileyo kwaye uthintele iingozi zombane. Xa ucinga ngokufaka ezi zixhobo, soloko unxibelelana nombane ofanelekileyo ukuqinisekisa ukuba uyayithobela imithetho nemigangatho yendawo.
