RCCB 4 Ncej 40A 63A 80A 30mA Hom B RCD Lub Ntiaj Teb Leakage Circuit Breaker rau DC 6mA EV Chaw Nres Tsheb
Residual Current Circuit Breaker (RCCB) lossis Residual Current Device (RCD) yog qhov tseem ceeb ntawm lub chaw nres tsheb charger.Nws yog cov cuab yeej kev nyab xeeb uas pab tiv thaiv tib neeg los ntawm hluav taws xob poob siab los ntawm qhov seem tam sim no.Thaum siv cov khoom siv hluav taws xob, tej zaum yuav muaj feem cuam tshuam txog tam sim no vim muaj kev cuam tshuam luv luv lossis kev cuam tshuam ntawm rwb thaiv tsev.Nyob rau hauv cov xwm txheej zoo li no, RCCB lossis RCD txiav tawm lub zog hluav taws xob sai li sai tau thaum nws pom qhov xau tam sim no, yog li tiv thaiv tib neeg los ntawm kev puas tsuaj.

IEC 62752: 2016 siv rau hauv-cable tswj thiab tiv thaiv cov cuab yeej (IC-CPDs) rau hom 2 them hluav taws xob tsheb tsheb, tom qab ntawd hu ua IC-CPD suav nrog kev tswj hwm thiab kev nyab xeeb.Cov txheej txheem no siv rau cov khoom siv nqa tau ib txhij ua haujlwm ntawm kev tshawb nrhiav qhov seem tam sim no, ntawm kev sib piv ntawm tus nqi ntawm qhov tam sim no nrog cov nqi khiav hauj lwm seem thiab qhib qhov kev tiv thaiv hluav taws xob thaum qhov seem tam sim no tshaj tus nqi no.
Feem ntau muaj ob hom RCCBs: Hom B thiab Hom A. Hom A feem ntau siv hauv tsev, qhov B yog nyiam nyob rau hauv chaw tsim khoom.Qhov laj thawj tseem ceeb yog, Hom B muab kev tiv thaiv ntxiv rau DC qhov seem tam sim no uas Hom A tsis muaj.
Hom B RCD zoo dua li Hom A raws li nws tuaj yeem ntes DC qhov seem tam sim no tsawg li 6mA, qhov hom A tsuas tuaj yeem ntes AC seem tam sim no.Hauv cov ntawv thov kev lag luam, DC seem tam sim no muaj ntau dua vim yog siv cov khoom siv DC-powered.Yog li, Hom B RCD yog qhov tsim nyog nyob rau hauv ib puag ncig zoo li no.
Qhov sib txawv tseem ceeb ntawm B hom thiab A hom RCD yog qhov ntsuas DC 6mA.DC residual tam sim no feem ntau tshwm sim hauv cov khoom siv uas hloov AC rau DC lossis siv lub roj teeb.Hom B RCD kuaj xyuas cov seem seem no thiab txiav tawm lub zog hluav taws xob, tiv thaiv tib neeg los ntawm hluav taws xob shocks.
