Cov xwm txheej ntawm daim ntawv thov ntawm RCCB

Cov xwm txheej siv ntawm cov khoom siv hluav taws xob seem (RCCB) yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm tib neeg thiab khoom vaj khoom tsev. Ua ntej nkag mus rau hauv cov xwm txheej siv tshwj xeeb, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab cai ntawm kev raug hluav taws xob thiab lub luag haujlwm ntawm RCCB hauv kev tiv thaiv kev raug hluav taws xob.

Kev raug hluav taws xob poob yog kev raug mob hnyav uas tshwm sim los ntawm kev hla dhau ntawm cov hluav taws xob hla lub cev tib neeg. Thaum ib tug neeg txhais tes kov cov xov hlau uas muaj sia, hluav taws xob tuaj yeem ntws hla lub cev, ua rau raug mob. Tom qab muaj kev raug hluav taws xob poob, yuav tsum txiav cov hluav taws xob sai li sai tau. Lub sijhawm txwv rau kev txiav cov hluav taws xob nyob ntawm qhov ntau ntawm cov hluav taws xob ntws hla lub cev. Piv txwv li, yog tias cov hluav taws xob yog 50mA, lub sijhawm txiav tawm yuav tsum tsis pub dhau 1 vib nas this. Yog tias cov hluav taws xob yog 500mA, lub sijhawm txiav tawm yuav luv dua rau 0.1 vib nas this.

A Cov Khoom Siv Hluav Taws Xob Tam Sim No (RCCB) yog ib lub cuab yeej siv hluav taws xob uas tsim los txiav lub hwj chim yog tias muaj hluav taws xob xau lossis hluav taws xob poob. Thaum lub hwj chim mus txog qhov tam sim no uas tau teeb tsa los ntawm lub qhov hloov tiv thaiv, RCCB yuav txiav lub hwj chim hauv ib lub sijhawm luv luv kom ntseeg tau tias tib neeg thiab khoom muaj kev nyab xeeb. Qhov no ua rau RCCB yog ib qho tseem ceeb ntawm kev nyab xeeb hluav taws xob hauv ntau yam xwm txheej.

Cov xwm txheej siv ntawm RCCB muaj ntau yam thiab npog ntau yam. Ib qho ntawm cov xwm txheej tseem ceeb yog cov kab faib khoom rau cov khoom siv hluav taws xob tuav thiab txawb, nrog rau cov khoom siv ruaj khov uas cov tib neeg yuav tsis tuaj yeem khiav tawm raws sijhawm yog tias muaj hluav taws xob raug mob. Tsis tas li ntawd, cov khoom siv hluav taws xob hauv chaw ua haujlwm sab nraum zoov thiab cov khoom siv hauv tsev lossis cov qhov hluav taws xob yuav tsum tau nruab nrog RCCBs nrog cov nqi tam sim no ua haujlwm tsis pub tshaj 30mA. Qhov no ua kom ntseeg tau tias cov tib neeg tau txais kev tiv thaiv los ntawm kev phom sij ntawm hluav taws xob hauv cov chaw no.

Lwm qhov teeb meem tseem ceeb ntawm RCCB yog lub teeb pom kev ntawm lub elevator uas siv AC 220V. Hauv qhov no, qhov hluav taws xob zoo tshaj plaws rau lub teeb pom kev ntawm lub elevator yog 36V. Txawm li cas los xij, thaum siv AC 220V, yuav tsum muaj RCCB ntsia kom muab kev tiv thaiv ntxiv. Tsis tas li ntawd, lub teeb yuav tsum muaj lub hau tiv thaiv kom txo qhov kev pheej hmoo ntawm kev raug hluav taws xob poob siab.

Hauv kev xaus lus, cov xwm txheej siv ntawm cov khoom siv hluav taws xob seem (RCCB) yog qhov tseem ceeb heev los tiv thaiv kev poob hluav taws xob thiab xyuas kom muaj kev nyab xeeb ntawm tib neeg thiab khoom vaj khoom tsev. Txij li cov khoom siv hluav taws xob tuav thiab txawb mus rau cov khoom siv hauv tsev thiab teeb pom kev zoo ntawm lub elevator, RCCBs ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov teebmeem tsis zoo ntawm kev poob hluav taws xob. Los ntawm kev nkag siab thiab kev siv cov xwm txheej siv rau RCCB, cov tib neeg thiab cov koom haum tuaj yeem tsim kom muaj ib puag ncig muaj kev nyab xeeb dua thiab txo qhov kev pheej hmoo ntawm kev raug mob hluav taws xob.
