Nkag Siab Txog Cov Khoom Siv Hluav Taws Xob Uas Siv Hluav Taws Xob Uas Muaj Cov Khoom Siv Hluav Taws Xob: Ib Phau Ntawv Qhia Txog Kev Siv Hluav Taws Xob
Hauv kev nyab xeeb ntawm hluav taws xob, cov khoom siv hluav taws xob seem (RCDs) ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv tib neeg thiab khoom vaj khoom tsev ntawm kev phom sij ntawm hluav taws xob. Tsab xov xwm no piav qhia txog kev ua haujlwm, qhov tseem ceeb, thiab kev siv ntawm cov khoom siv hluav taws xob seem (RCDs), lub hom phiaj yog los pab cov neeg nyeem kom nkag siab txog cov khoom siv tseem ceeb no.
Lub tshuab hluav taws xob seem (RCD) yog dab tsi?
Ib lub cuab yeej tiv thaiv hluav taws xob seem (RCD) yog ib lub cuab yeej tiv thaiv kev nyab xeeb uas tsim los tiv thaiv kev poob hluav taws xob thiab hluav taws xob los ntawm kev puas tsuaj ntawm av. Nws ua haujlwm los ntawm kev saib xyuas qhov hluav taws xob hauv lub voj voog. Yog tias nws pom qhov tsis sib npaug ntawm qhov hluav taws xob ntawm cov xov hlau nyob (theem) thiab cov xov hlau nruab nrab, qhia tias qhov hluav taws xob xau rau cov xov hlau av, RCD yuav txiav lub voj voog sai sai. Qhov kev teb sai no - feem ntau yog nyob rau hauv30 milliseconds—tiv thaiv cov xwm txheej me me kom tsis txhob loj hlob mus ua qhov xwm txheej txaus ntshai rau lub neej.
Qhov txawv ntawm tus breaker txheem thiab tus RCD breaker yog dab tsi?
Qhov txawv tseem ceeb ntawm RCD thiab lub circuit breaker yog lawv lub hom phiaj: RCD: Tiv thaiv tib neeg ntawm kev raug hluav taws xob lossis kev raug hluav taws xob los ntawm kev ntes cov hluav taws xob xau. Circuit Breaker: Tiv thaiv cov kab ke hluav taws xob thiab cov khoom siv los ntawm kev txiav lub zog thaum muaj hluav taws xob ntau dhau lossis luv luv.
Lub hauv paus ntsiab lus ua haujlwm ntawm cov khoom siv tam sim no (RCD) hauv lub tshuab hluav taws xob Circuit Court yog dab tsi?
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab hluav taws xob seem (RCD) yog raws li lub hauv paus ntsiab lus ntawm qhov sib txawv ntawm qhov hluav taws xob. Raws li qhov xwm txheej ib txwm muaj, qhov hluav taws xob ntws los ntawm cov xov hlau uas muaj sia yuav tsum sib npaug rau qhov hluav taws xob ntws los ntawm cov xov hlau nruab nrab. Txawm li cas los xij, yog tias muaj qhov tsis zoo tshwm sim, xws li hluav taws xob poob siab lossis hluav taws xob puas tsuaj, qee qhov hluav taws xob yuav xau mus rau cov xov hlau hauv av. RCD pom qhov tsis sib npaug ntawm qhov hluav taws xob no thiab mus txuas ntxiv txiav lub voj voog, yog li txiav tawm lub zog fais fab.
Cov khoom siv hluav taws xob seem (RCDs) muaj ntau yam kev ntsuas, feem ntau yog los ntawm30 mA rau kev tiv thaiv tus kheej to 100 mA lossis 300 mA rau kev tiv thaiv hluav tawsCov qib qis dua txhais tau tias lub cuab yeej rhiab heev rau cov hluav taws xob xau, ua rau RCDs tseem ceeb hauv cov chaw uas kev nyab xeeb ntawm tus kheej yog qhov txhawj xeeb tseem ceeb.
Qhov Tseem Ceeb ntawm Cov Khoom Siv Hluav Taws Xob Tam Sim No
Qhov tseem ceeb ntawm cov khoom siv hluav taws xob seem (RCD) hauv cov hluav taws xob Circuit Breakers tsis tuaj yeem tsis quav ntsej. Lawv yog qhov tseem ceeb rau kev tiv thaiv kev raug mob hluav taws xob uas tuaj yeem ua rau raug mob hnyav lossis tuag taus. Cov ntaub ntawv qhia tau tias RCDs tuaj yeemtxo qhov kev pheej hmoo ntawm kev raug hluav taws xob poob siab txog li 90%Qhov no ua rau lawv yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob hauv tsev, kev lag luam, thiab kev lag luam.
Ntxiv rau qhov ua kom muaj kev nyab xeeb rau tus kheej, cov khoom siv hluav taws xob seem (RCDs) kuj tseem tiv thaiv cov khoom siv hluav taws xob kom tsis txhob puas tsuaj. Kev puas tsuaj ntawm hluav taws xob tuaj yeem ua rau kub dhau thiab hluav taws, ua rau muaj kev puas tsuaj loj rau cov khoom. RCDs pab txo cov kev pheej hmoo no los ntawm kev txiav lub voj voog thaum muaj teeb meem, yog li ua rau lub neej ntawm cov kab ke hluav taws xob thiab cov khoom siv ntev dua.
Daim Ntawv Thov ntawm Cov Khoom Siv Tiv Thaiv Circuit Breaker Tam Sim No
Cov khoom siv hluav taws xob seem (RCDs) siv dav hauv ntau qhov chaw. Hauv cov tsev nyob, lawv feem ntau raug teeb tsa rau hauv cov thawv faib khoom los tiv thaiv cov voj voog xa hluav taws xob rau cov qhov hluav taws xob, teeb pom kev zoo, thiab cov khoom siv sab nraum zoov. Hauv cov tsev lag luam, RCDs yog qhov tseem ceeb rau kev tiv thaiv cov neeg ua haujlwm thiab cov neeg siv khoom, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj dej, xws li chav ua noj thiab chav dej.
Hauv cov chaw ua haujlwm, cov khoom siv tiv thaiv tam sim no (RCDs) tseem ceeb heev rau kev tiv thaiv cov tshuab thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm uas yuav ntsib kev phom sij ntawm hluav taws xob. Ntxiv mus, cov cai thiab cov cai tswjfwm hluav taws xob feem ntau yuav tsum tau teeb tsa RCDs, ua rau lawv yog ib feem ntawm kev teeb tsa hluav taws xob niaj hnub.
Hauv luv luv
Hauv kev xaus lus, cov khoom siv hluav taws xob seem (RCDs) yog cov khoom siv tseem ceeb hauv kev nyab xeeb hluav taws xob. Lawv tuaj yeem ntes tau sai thiab teb rau qhov tsis ua haujlwm hluav taws xob, ua rau lawv yog ib qho tseem ceeb hauv kev tiv thaiv lub neej thiab khoom vaj khoom tsev. Txawm hais tias nyob hauv tsev, lag luam, lossis chaw ua haujlwm, kev teeb tsa cov RCDs hom hluav taws xob yog ib qho kev ntsuas ua ntej uas tuaj yeem txhim kho kev nyab xeeb thiab txo qhov kev pheej hmoo ntawm kev raug mob hluav taws xob. Nrog rau kev nce qib ntawm thev naus laus zis, kev tsim qauv thiab kev ua haujlwm ntawm RCDs tau txhim kho tas li, kom ntseeg tau tias lawv tseem nyob rau pem hauv ntej ntawm kev daws teeb meem kev nyab xeeb hluav taws xob.
