Nkag siab txog qhov tseem ceeb ntawmRCCB nrog kev tiv thaiv kev thauj khoom ntau dhau
Thaum nws los txog rau kev nyab xeeb ntawm hluav taws xob, kev siv cov kev tiv thaiv kom raug yog qhov tseem ceeb heev. RCCB nrog kev tiv thaiv kev thauj khoom ntau dhau yog ib qho ntawm cov khoom tseem ceeb hauv txhua lub tshuab hluav taws xob. Lub cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev raug mob hluav taws xob thiab ua kom muaj kev nyab xeeb ntawm tib neeg thiab khoom vaj khoom tsev.
RCCB sawv cev rau Residual Current Circuit Breaker thiab yog ib lub cuab yeej kev nyab xeeb tseem ceeb uas ntes thiab qhib lub voj voog hluav taws xob thaum pom muaj qhov tsis zoo xws li qhov hluav taws xob xau lossis tsis sib npaug ntawm hluav taws xob. Qhov no pab tiv thaiv kev poob hluav taws xob thiab hluav taws, ua rau nws yog ib feem tseem ceeb ntawm kev teeb tsa hluav taws xob.
Txawm li cas los xij, tsuas yog nruabRCCBtsis txaus. Nws tseem ceeb heev uas lub cuab yeej muaj kev tiv thaiv overload uas ua tiav lawm. Lub hom phiaj ntawm kev tiv thaiv overload yog txiav tawm lub voj voog thaum tam sim no tshaj qhov muaj peev xwm ntsuas ntawm lub voj voog. Qhov no yog qhov tseem ceeb rau kev tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob thiab tiv thaiv kev ncaj ncees ntawm lub kaw lus hluav taws xob.
Yog li ntawd, vim li cas RCCB uas muaj kev tiv thaiv kev thauj khoom ntau dhau thiaj li tseem ceeb? Cia peb saib ze dua seb yog vim li cas:
1. Tiv thaiv kev raug mob hluav taws xob
Kev raug mob los ntawm hluav taws xob tuaj yeem ua rau muaj kev puas tsuaj loj heev, ua rau raug mob hnyav, tuag thiab puas tsuaj rau khoom vaj khoom tsev. RCCBs nrog kev tiv thaiv kev thauj khoom ntau dhau pab tiv thaiv cov xwm txheej no los ntawm kev qhib lub voj voog thaum pom muaj qhov txhaum lossis kev thauj khoom ntau dhau, yog li txo qhov kev pheej hmoo ntawm kev raug hluav taws xob thiab hluav taws kub.
2. Tiv thaiv cov khoom siv hluav taws xob
Ntxiv rau kev tiv thaiv kev raug mob hluav taws xob, kev tiv thaiv overload kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv hluav taws xob. Thaum tam sim no tshaj qhov peev xwm ntsuas ntawm lub voj voog, nws tuaj yeem ua rau cov khoom siv hluav taws xob, tshuab, thiab lwm yam khoom siv hluav taws xob puas tsuaj. Nrog kev tiv thaiv overload, lub voj voog raug txiav tawm ua ntej muaj kev puas tsuaj tshwm sim, ua kom ntseeg tau tias lub neej ntev thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob.
3. Xyuas kom ua raws li cov cai kev nyab xeeb
Hauv ntau lub tebchaws, suav nrog Tebchaws Meskas thiab European Union, muaj cov cai tswjfwm kev nyab xeeb nruj rau kev teeb tsa cov tshuab hluav taws xob. Cov cai no feem ntau yuav tsum tau siv RCCBs nrog kev tiv thaiv kev thauj khoom ntau dhau kom ntseeg tau tias muaj kev nyab xeeb ntawm kev teeb tsa hluav taws xob. Los ntawm kev ua cov kev tiv thaiv tsim nyog, koj tuaj yeem ua kom ntseeg tau tias ua raws li cov cai no thiab zam kev raug cai thiab kev nyiaj txiag.
4. Kev thaj yeeb ntawm lub siab
Kev teeb tsa RCCB nrog kev tiv thaiv kev thauj khoom ntau dhau tuaj yeem ua rau cov tswv tsev thiab cov tswv lag luam muaj kev thaj yeeb nyab xeeb. Kev paub tias koj lub tshuab hluav taws xob tau nruab nrog cov kev ntsuas kev nyab xeeb kom raug tuaj yeem txo qhov kev txhawj xeeb txog kev nyab xeeb hluav taws xob thiab txo qhov kev pheej hmoo ntawm kev raug mob lossis kev puas tsuaj.
Hauv kev xaus lus, ib qhoRCCB nrog kev tiv thaiv kev thauj khoom ntau dhauyog ib feem tseem ceeb ntawm txhua lub tshuab hluav taws xob. Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev raug mob hluav taws xob, tiv thaiv cov khoom siv hluav taws xob, ua kom ua raws li cov cai kev nyab xeeb, thiab muab kev thaj yeeb nyab xeeb rau cov tswv. Yog tias koj tab tom txhim kho lossis hloov kho lub tshuab hluav taws xob, nco ntsoov siv RCCBs nrog kev tiv thaiv kev thauj khoom ntau dhau kom ntseeg tau tias muaj kev nyab xeeb thiab kev ncaj ncees ntawm koj qhov kev teeb tsa hluav taws xob.
