I-China Umephuli wojikelezo Umenzi, umthengisi, umzi-mveliso

I-2p ye-RCbo B Uhlobo lomphulaphuli omabini olwenziweyo ngokugqithileyo Uhlobo oluthi "luhlala lubhekisa kuhlobo oluthile okanye ukucaciswa komphuli wesekethe, olunokubandakanya iimpawu zokusebenza, ikalwe nge-voltage yangoku, ezinye iiparamitha zesekethe.

Uhlobo lwe-4P RCBO AC luyi-4-pole breaker circuit breaker edibanisa ukukhuselwa kwangoku okushiyekileyo kunye nemisebenzi yokukhusela i-overcurrent, ngokukodwa eyenzelwe ukutshintshiselana kweesekethe zangoku (AC). Inokuthi inqumle unikezelo lwamandla ngokuzenzekelayo xa intsalela yangoku (okt ukuvuza kwangoku) ifunyenwe kwisekethe ukuthintela imililo yombane kunye neengozi zokothuka zombane. Ngelo xesha, nayo inomsebenzi wokukhusela ogqithisiweyo onokuthi unqumle ngokuzenzekelayo ukunikezelwa kwamandla xa kwenzeka ukugqithisa okanye i-short-circuit kwisekethe ukukhusela ukhuseleko lwesiphaluka kunye nezixhobo.

I-2P ye-2P 1p + i-hit + i-NUSTAL STETRORT ENGCWANGCISO NGOKUSETYENZISELWEYO ngumphunga wesekethe odibanisa ukhuseleko lwangoku kunye nokukhuselwa ngaphezulu. Kuyakwazi ukusika ngokuzenzekelayo ukubonelela ngamandla xa intsalela entsalela (i.e. Ukuvuza okwangoku kufunyanwa kwisekethe ukuthintela imililo yombane kunye neengozi zombane. Kwangelo xesha, ikwanomsebenzi wokhuselo ogqithisileyo, olunokunqunyulwa ngokuzenzekelayo ukuhambisa amandla xa isekethe lilayishwe kakhulu okanye likufutshane ukukhusela ukhuseleko lwesekethe kunye nezixhobo.

I-1P + uhlobo lwe-elektroniki i-rcbois uhlobo olukhethekileyo lomphunga wesekethe osebenzisa umgaqo wesekethe wokufumanisa kwaye unqumle i-Ofisi yentsalela (ukuvuza okwangoku) kwingozi yombane kunye neengozi zomoyikiso zothusa zomoya. Kwangelo xesha, ikwanomsebenzi wokhuselo ogqithisileyo, olunokunqunyulwa ngokuzenzekelayo ukuhambisa amandla xa isekethe lilayishwe kakhulu okanye likufutshane ukukhusela ukhuseleko lwesekethe kunye nezixhobo.

Uhlobo lwe-elektroniki i-RCO inokuqhagamshela kwaye iphule okwangoku kwisekethe ephambili, kwaye inqumle ngokuzenzekelayo isekethe xa intsalela (ukuvuza okwangoku) yenzeka kwisekethe enkulu, okanye ingozi yombane. Kwangelo xesha, i-RCBO ikwanomsebenzi wokhuselo olugqithisileyo, olunokunqunyulwa isekethe xa kugqitha okanye kusenzeka kwisekethe elifutshane kwisekethe ukukhusela ukhuseleko lwesekethe kunye nezixhobo.

Olu hlobo lwe-4p 63a / 30ma i-racd ye-CCD ibangela indlela yangaphakathi ye-RCD yangaphakathi, ebangela i-RCD yokuyeka ukusika amandla, ngaloo ndlela ekhusela ukhuseleko lwezixhobo zombane nabasebenzi.
