Cov cuab yeej hluav taws xob seem (RCCBs)yog cov khoom siv kev nyab xeeb tseem ceeb siv rau hauv kev teeb tsa hluav taws xob los tiv thaiv cov hluav taws xob txaus ntshai. Nws muab kev tiv thaiv zoo dua tiv thaiv kev pheej hmoo ntawm kev poob siab hluav taws xob thiab hluav taws kub los ntawm kev ua tsis tiav ntawm lub tshuab hluav taws xob.
Ib qho ntawm cov haujlwm tseem ceeb ntawm ib qhoRCCByog nrhiav seb puas muaj qhov xau lossis tsis sib npaug ntawm cov hluav taws xob tam sim no. Nws ua haujlwm los ntawm kev sib piv cov hluav taws xob nkag thiab cov zis tam sim no hauv lub voj voog. Yog tias muaj qhov sib txawv ntawm ob qho, nws txhais tau tias muaj cov hluav taws xob xau thiab muaj qhov tsis zoo hauv lub kaw lus.RCCBces sai sai cuam tshuam lub voj voog, txiav lub zog thiab tiv thaiv kom tsis txhob muaj kev puas tsuaj.
Qhov tseem ceeb ntawmRCCBnws muaj peev xwm tiv thaiv tau ob hom kev puas tsuaj: kev puas tsuaj hauv av thiab kev xau hluav taws xob. Kev puas tsuaj hauv av tshwm sim thaum tus neeg hluav taws xob kov lub ntiaj teb ncaj qha, ua rau luv luv Circuit. Kev xau hluav taws xob, ntawm qhov tod tes, tuaj yeem tshwm sim thaum cov khoom rwb thaiv tsev tsis ua haujlwm lossis thaum kev sib txuas hluav taws xob tsis muaj zog.
RCCBsyog qhov tseem ceeb tshwj xeeb hauv cov chaw nyob hauv tsev uas muaj kev pheej hmoo ntawm kev raug mob hluav taws xob vim yog cov xov hlau tsis raug lossis cov khoom siv puas tsuaj ntau dua. RCCB tiv thaiv lub neej thiab cov khoom vaj khoom tsev ntawm cov neeg nyob hauv tsev los ntawm kev ntes thiab cuam tshuam txhua qhov tsis ua haujlwm sai sai, tiv thaiv kev poob hluav taws xob thiab hluav taws kub.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tiasRCCBstsis txhob hloov cov fuses lossis cov khoom siv tiv thaiv overcurrent. Hloov chaw, nws ua kom tiav lawv los ntawm kev muab ib txheej ntxiv ntawm kev tiv thaiv tshwj xeeb tiv thaiv cov av tsis ua haujlwm thiab cov dej ntws tawm. Yog li ntawd, nws raug pom zoo kom nruabRCCBib sab ntawm cov khoom siv tiv thaiv hluav taws xob uas twb muaj lawm kom ntseeg tau tias muaj kev nyab xeeb hluav taws xob tag nrho.
Hauv luv luv, qhovlub ntiaj teb leakage circuit breakeryog ib qho khoom siv kev nyab xeeb tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev raug mob hluav taws xob. Los ntawm kev ntes thiab cuam tshuam cov voj voog tsis zoo sai sai, nws tuaj yeem tiv thaiv kev poob hluav taws xob thiab hluav taws, yog li ua kom muaj kev nyab xeeb hluav taws xob hauv tsev thiab lwm qhov chaw. Kev nqis peev hauvRCCByog ib qho kev txiav txim siab ntse vim nws muab kev tiv thaiv ntxiv rau cov tswv tsev thiab kev thaj yeeb nyab xeeb ntawm lub siab.
