Ukuqonda ukubaluleka kwe-1p + N MCB kunye ne-RCD kuKhuseleko loMbane

Kwinkalo yokhuseleko lombane,1p + N MCBs kunye nee-RCDs zidlala indima ebalulekileyo ekukhuseleni abantu kunye nepropathi ekutshatyalalisweni kombane kunye nomlilo. I-2-pole RCD eshiyekileyo ye-circuit breaker, ekwabizwa ngokuba yi-Type AC okanye Uhlobo lwe-A RCCB JCRD2-125, isaphuli sesekethe yangoku esibuthathaka eyenzelwe ukukhusela abasebenzisi kunye nempahla yabo. Esi sixhobo esitsha sisebenza ngokuphazamisa ukuhamba kombane njengoko udlula kwiyunithi yabathengi okanye ibhokisi yokuhambisa ukuba kukho ukungalingani okanye ukuphazamiseka kwindlela yangoku.

1p+N MCB(okanye i-Miniature Circuit Breaker) yinto ebalulekileyo kwiinkqubo zombane. Yenzelwe ukuvala ngokuzenzekelayo isiphaluka xa kufunyenwe impazamo, ukuthintela umonakalo kwiingcingo kunye nezixhobo zokusebenza. Xa idityaniswe ne-RCD, i-1p + N MCB ibonelela ngesisombululo esibanzi sokhuseleko kwindawo yokuhlala kunye nofakelo lombane loshishino.

I-2-pole RCD i-residual current circuit breakers ezifana ne-JCRD2-125 inika ukhuseleko oluphezulu malunga nokutshitshiswa kombane kunye nomlilo onokubakho. Uvakalelo lwayo kukungalingani kwangoku luyenza ibe sisixhobo esiyimfuneko kwiinkqubo zombane zanamhlanje. I-RCD ikhusela iimeko ezinobungozi kwaye iqinisekisa ukhuseleko lwabantu kunye nepropati ngokuphazamisa ngokukhawuleza okwangoku xa kwenzeka iphutha.

I-JCR2-125 RCD yenzelwe ukuhlangabezana neyona migangatho iphezulu yokhuseleko, inika abasebenzisi kunye nabafakeli uxolo lwengqondo. Ikhono layo lokubona kunye nokuphendula ukungalingani kwangoku kuncinci kwenza kube yinto ethembekileyo nesebenzayo yokhuseleko. Ngohlobo lwayo lwe-AC okanye uhlobo lwe-A, i-JCR2-125 i-RCD inikezela ngeendlela ezahlukeneyo kunye nokulungelelaniswa kokufakelwa kombane okwahlukeneyo, okwenza kube yinto yokuqala yokukhetha iingcali zoshishino.

Indibaniselwano ye1p+N MCBkunye ne-2-pole RCD i-residual current circuit breaker ibalulekile ukuqinisekisa ukhuseleko lombane kwiindawo zokuhlala kunye nezorhwebo. Ezi zixhobo zisebenza kunye ukuze zibone iimpazamo, zithintele ukutshitshiswa kombane kunye nokunciphisa umngcipheko womlilo, zibonelela ngesisombululo esibanzi sokhuseleko kwiinkqubo zombane zanamhlanje. I-JCR2-125 RCD inikezela ngeempawu eziphambili kunye novelwano oluphezulu, olubandakanya ukuzinikela kukhuseleko nokuthembeka kofakelo lombane. Ngokuqonda ukubaluleka kwala macandelo kunye nokutyalomali kwiimveliso ezisemgangathweni, abantu kunye namashishini banokubeka phambili ukhuseleko kunye nokukhusela iimpahla zabo kwiingozi ezinokuthi zibe nombane.
