Intsalela yesekethe eyangoku ishiyekileyo yokhuseleko olugqithisileyo (i-RCBO), ngokwenene luhlobo lomphunga wesekethe onomsebenzi wokhuselo lokuvuza. I-RCB inomsebenzi wokukhusela ngokuvuza, ukothuka kombane, ukulayisha ngaphezulu kunye nesekethe emfutshane. I-RCBO inokuthintela ukwenzeka kweengozi zothuso lomoya kwaye inefuthe elibonakalayo lokuphepha iingozi zomlilo ezibangelwa kukuvuza kombane. I-RCBOs ifakwe kwiibhokisi zethu eziqhelekileyo zokuhambisa ekhaya ukuqinisekisa ukhuseleko lwabantu. I-RCB luhlobo lomphunga oludibanisa i-MCB kunye ne-RCD kwi-RCD kwilinye i-SCD elinye. I-RCBOs ingangena kwi-1 pole, i-1 + izibonda ezibini okanye izibonda ezi-4 kunye ne-AMP kwi-A, i-o, i-C, i-A, i-A, i-A kunye I-AC.
Kuya kufuneka usebenzise i-rcbo ngezizathu ezifanayo esicebisa nge-rcb - ukusindisa kwi-elektroction ngengozi kwaye kuthintele imililo yombane. I-RCBO inazo zonke iimpawu ze-RCD ngomchiza ogqithileyo.
I-RCD luhlobo lomphunga wesekethe olunokuvula ngokuzenzekelayo umphuli emva kwetyala lomhlaba. Lo mtyholi wenzelwe ukukhusela umngcipheko wokubeka umngcipheko kwi-elektrocal yengozi kunye nomlilo obangelwa ziimpazamo zomhlaba. I-Wordiders ikwayibiza ngokuba yi-RCD (iSixhobo esikhoyo) kunye ne-RCCB (umphunga wesekethe) ophumeleleyo. Unokukhetha ukusuka kwizibonda ezi-2 okanye ezi-4, i-AMP isuka kwi-25 A ukuya kuthi ga kwi-100 A, i-curve ye-b, chwetheza i-B, i-AC kunye ne-Matring ukusuka kwi-30 ma.
Ngokufanelekileyo, kuya kuba kuhle ukusebenzisa olu hlobo lomphulaphuli ukuthintela imililo ngengozi kunye ne-elektrocy. Nakuphi na ukudlula komntu obonakalayo ngakumbi kune-30 man inokuqhuba intliziyo ibe yintliziyo ye-ventricular fibrillation (okanye iphosa isingqisho sentliziyo). I-RCD imisa i-25 ukuya kwi-40 millisecond ngaphambi kokothusa ngombane. Ngokwahlukileyo, abaphulaphuli besekethe abaqhelekileyo njenge-MCB / McCB (i-Minity (i-Minity (i-fus yekhefu kuphela xa okwangoku kwisekethe igqithisileyo Ukuvuza okuncinci okuvuzayo ngoku ngomzimba womntu kunokwanela ukukubulala. Nangona kunjalo, kungenzeka ukuba iyonyuse iyonke epheleleyo ye-fuse okanye ilayishe ngaphezulu komphuli wesekethe kwaye ungakhawulezi ngokwaneleyo ukusindisa ubomi bakho.
Umahluko ophambili phakathi kwaba bobuqhetseba sesekethe kukuba i-RCBO ixhotywe ngumgcini ongaphezulu. Okwangoku, usenokucinga ngesizathu sokuba bathengise ngokwahlukeneyo ukuba kubonakala ngathi kukho umahluko omkhulu phakathi kwabo? Kutheni ungathengisi kuphela kwintengiso? Nokuba ukhetha ukusebenzisa i-RCBO okanye i-RCD ixhomekeke kuhlobo lofakelo kunye nohlahlo-lwabiwo mali. Umzekelo, xa kukho umhlaba ukuvuza kwibhokisi yokuhambisa usebenzisa onke ababhuli eRCbo, kuphela umphulaphuli otyhafileyo uya kuhamba. Nangona kunjalo, olu hlobo lweendleko zesimo ziphezulu kune-RCD's. Ukuba uhlahlo-lwabiwo mali lungumcimbi, unokuqwalasela ezintathu ze-MCB ezine phantsi kwesixhobo esinye sentsalela. Ungayisebenzisa nangezicelo ezizodwa ezinjengejacuzi okanye ukufakwa kwetyhubhu eshushu. Olu kufakekelo lufuna ukuba isebenze ngokukhawuleza kwaye incinci isebenze ngoku, ngokubanzi i-10ma. Ekugqibeleni, nayiphi na i-whichever ofuna ukuyisebenzisa ixhomekeke kuYilo lwakho lweSwitchboard kunye noHlahlo-lwabiwo mali. Nangona kunjalo, ukuba uza kuyila okanye uphucule i-switchboard yakho ukuze uhlale kumgaqo kwaye uqiniseke ukuba usebenzise umbane ofanelekileyo kuzo zombini iiasethi zeasethi kunye nobomi bomntu, qinisekisa ukuba unxibelelana ngengcali yombane othembekileyo.
I-AFD sisixhobo esibonakalayo se-ARC kwaye yenzelwe ukukhangela ubukho bee-ARCs zombane eziyingozi kwaye unqamle kwisekethe echaphazelekayo. Umsebenzi wokuKhubazeka we-ARC Umsebenzi usebenzisa itekhnoloji ye-microprocesm ukuhlalutya i-wavefofonte yombane. Babona naluphi na utyikityo olungaqhelekanga olunokuthetha i-arc kwisekethe. I-AFD iya kuthi iphelise amandla kwisekelo echaphazelekileyo ethintela ngokufanelekileyo umlilo. Zijongeke kakhulu kwi-ARCs kunezixhobo zokukhusela eziqhelekileyo ezifana ne-MCBS kunye ne-RBCOS.
