A Circuit Court breaker nrog kev tiv thaiv overload(feem ntau hu uaRCBO) yog ib qho tseem ceeb hauv txhua lub voj voog hluav taws xob. Nws lub luag haujlwm tseem ceeb yog los tiv thaiv ob hom kev ua txhaum hluav taws xob: tam sim no seem thiab overload. Tsab xov xwm no yuav nkag mus rau hauv qhov nyuaj ntawmRCBOthiab piav qhia nws qhov tseem ceeb thiab kev ua haujlwm.
An RCBOyog ib lub cuab yeej uas muab cov haujlwm ntawm cov khoom siv tam sim no (RCD) thiab lub tshuab hluav taws xob sib txuas ua ke. Qhov kev koom ua ke no ua rau nws yog ib qho cuab yeej ruaj ntseg tseem ceeb, tshwj xeeb tshaj yog nyob hauv tsev thiab hauv chaw ua haujlwm. Ua ntej,Cov RCBOtiv thaiv cov teeb meem tam sim no uas tseem tshuav, uas tshwm sim thaum lub tshuab hluav taws xob tsis sib npaug ua rau muaj hluav taws xob xau. Qhov xwm txheej no yuav tshwm sim los ntawm cov khoom siv tsis zoo, cov xov hluav taws xob puas, lossis cov xwm txheej ntub dej. RCBO yuav ntes tau txhua qhov xau, tam sim ntawd ua rau lub voj voog tawg thiab txo qhov kev pheej hmoo ntawm kev raug hluav taws xob poob thiab hluav taws kub.
Qhov thib ob, RCBO muab kev tiv thaiv kev overload. Overload tshwm sim thaum lub voj voog raug rau ntau dhau tam sim no uas tshaj nws lub peev xwm. Qhov no tuaj yeem tshwm sim los ntawm ntau lub cuab yeej muaj zog heev uas tau ntsaws rau hauv lossis muaj teeb meem hluav taws xob hauv lub cuab yeej. Yog tsis muajRCBO, hluav taws xob ntau dhau tuaj yeem ua rau cov xov hlau kub dhau, ua rau muaj hluav taws xob kub hnyiab. Txawm li cas los xij, yog tias hluav taws xob ntau tshaj qhov ntsuas tau teev tseg, qhovRCBOyuav ua rau lub voj voog tam sim ntawd, tiv thaiv kev puas tsuaj ntxiv.
Kev teeb tsa ntawm ib qhoRCBOyog ib qho txheej txheem yooj yim heev. Feem ntau nws raug ntsia rau ntawm lub vaj huam sib luag hluav taws xob thiab txuas nrog lub voj voog siv cov xov hlau. Lub cuab yeej muaj ntau yam ntxwv xws li kev teeb tsa tam sim no hloov kho tau, cov nyees khawm sim thiab cov txheej txheem teeb liab rau kev yooj yim siv thiab kev saib xyuas tsis tu ncua.
RCBO tsis yog tsuas yog ua kom muaj kev nyab xeeb ntawm hluav taws xob xwb, tab sis kuj muab kev yooj yim. Yog tias muaj teeb meem hluav taws xob, lub tshuab hluav taws xob ib txwm muaj feem ntau txiav hluav taws xob rau tag nrho lub voj voog, ua rau tag nrho cov khoom siv txuas nrog tsis muaj zog. Txawm li cas los xij,Cov RCBOua qee yam xaiv, tsuas yog ua rau cov voj voog uas cuam tshuam xwb. Qhov no ua rau muaj kev cuam tshuam tsawg kawg nkaus vim tias lwm yam ntawm lub kaw lus hluav taws xob tuaj yeem ua haujlwm tsis muaj kev cuam tshuam.
Hauv kev xaus lus, ibLub tshuab hluav taws xob seem tam sim no (RCBO) nrog kev tiv thaiv kev thauj khoom ntau dhauyog ib qho tseem ceeb hauv txhua lub tshuab hluav taws xob. Nws tiv thaiv kev poob hluav taws xob, hluav taws, thiab kev puas tsuaj rau cov khoom siv thiab cov voj voog los ntawm kev muab kev tiv thaiv tiv thaiv cov teeb meem tam sim no thiab kev thauj khoom ntau dhau.RCBOua ke cov yam ntxwv kev nyab xeeb nrog kev yooj yim kom ntseeg tau tias kev ua haujlwm hluav taws xob du thiab muaj kev nyab xeeb, ua rau cov tswv tsev thiab cov neeg ua haujlwm muaj kev thaj yeeb nyab xeeb.
