Lub ntiaj teb Leakage Circuit Breakers: Txhim kho hluav taws xob kev nyab xeeb los ntawm kev tshawb pom thiab tiv thaiv kev ua txhaum hauv av

Nov-26-2024
hluav taws xob

An Ntiaj teb Leakage Circuit Breaker (ELCB)yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob kev nyab xeeb uas tsim los tiv thaiv hluav taws xob thiab tiv thaiv hluav taws xob hluav taws xob. Los ntawm kev kuaj xyuas thiab cuam tshuam tam sim ntawm qhov ntws ntawm qhov tam sim no thaum lub ntiaj teb to lossis av txhaum, ELCBs ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev nyab xeeb hauv ntau qhov chaw. Kab lus no qhia txog kev ua haujlwm, hom, kev siv, thiab cov txiaj ntsig ntawm ELCBs, hais txog lawv qhov tseem ceeb hauv kev nyab xeeb hluav taws xob.

Dab tsi yog ibNtiaj teb Leakage Circuit Breaker?

Lub Ntiaj Teb Leakage Circuit Breaker (ELCB) yog tsim los xyuas thiab teb rau cov dej ntws tawm uas khiav tawm ntawm lub tshuab hluav taws xob mus rau hauv av. Cov dej ntws tawm no, txawm tias me me, tuaj yeem ua rau muaj kev pheej hmoo loj, suav nrog hluav taws xob thiab hluav taws xob hluav taws xob. Lub ELCB saib xyuas qhov sib txawv ntawm qhov tam sim no ntawm cov nquag (nyob) thiab nruab nrab conductors ntawm ib lub voj voog. Yog tias kuaj pom qhov tsis sib xws, qhia tias qee qhov tam sim no nkag mus rau hauv lub ntiaj teb, ELCB tawm mus rau hauv Circuit Court, txiav tawm lub zog hluav taws xob los tiv thaiv kev xau ntxiv thiab muaj kev phom sij.

ELCB Ua Haujlwm Li Cas?

ELCBs ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev txheeb xyuas qhov sib txawv tam sim no. Lawv tsis tu ncua saib xyuas tam sim no ntws los ntawm cov neeg ua haujlwm nquag thiab nruab nrab. Raws li ib txwm muaj, qhov tam sim no ntws mus rau hauv Circuit Court los ntawm tus neeg xyuas pib ua haujlwm yuav tsum sib npaug ntawm qhov tam sim no rov qab los ntawm tus neeg xyuas pib nruab nrab. Yog tias muaj qhov tsis sib xws, nws qhia tau tias muaj cov dej ntws ntws mus rau lub ntiaj teb.

Lub ELCB muaj lub tshuab hloov tam sim no uas kuaj pom qhov tsis sib xws. Thaum qhov sib txawv tam sim no tshaj qhov pib ua ntej, feem ntau 30mA, ELCB ua rau lub tshuab hluav taws xob relay uas cuam tshuam rau hauv Circuit Court, yog li nres qhov ntws ntawm tam sim no thiab txo qhov kev pheej hmoo ntawm hluav taws xob poob lossis hluav taws.

Hom Lub Ntiaj Teb Leakage Circuit Breakers

Muaj ob hom ELCBs: Voltage Earth Leakage Circuit Breakers (voltage ELCBs) thiab Current Earth Leakage Circuit Breakers (ELCBs tam sim no), tseem hu ua Residual Current Devices (RCDs).

Voltage Earth Leakage Circuit Breakers (Voltage ELCBs)

Voltage ELCBs yog tsim los saib xyuas qhov voltage ntawm lub ntiaj teb tus neeg xyuas pib. Yog tias qhov hluav taws xob ntau dhau ntawm qhov chaw pib, qhia txog qhov xau tam sim no, ELCB yuav mus rau hauv Circuit Court. Cov hom ELCBs no muaj tsawg dua niaj hnub no thiab tau hloov pauv los ntawm ELCBs tam sim no vim muaj qee qhov kev txwv, xws li tsis muaj peev xwm txheeb xyuas cov dej xau me me tau zoo.

Tam sim no Lub Ntiaj Teb Leakage Circuit Breakers (ELCBs lossis RCDs tam sim no)

Tam sim no ELCBs, lossis Cov Khoom Siv Hluav Taws Xob (RCDs), tau siv dav dua thiab suav tias muaj kev ntseeg siab dua. Lawv saib xyuas qhov tsis sib xws ntawm cov dej nyob thiab nruab nrab. Thaum kuaj pom qhov sib txawv tam sim no, RCD tawm mus rau hauv Circuit Court. ELCBs tam sim no muaj kev nkag siab zoo thiab tuaj yeem ntes cov xau me me, muab kev tiv thaiv zoo dua.

Kev siv lub ntiaj teb Leakage Circuit Breakers

ELCBs yog qhov tseem ceeb hauv ib puag ncig uas muaj kev nyab xeeb hluav taws xob yog qhov tseem ceeb. Lawv yog ib qho tseem ceeb tshwj xeeb hauv qhov chaw ntub dej lossis qhov chaw ntub dej uas qhov kev pheej hmoo ntawm hluav taws xob raug mob siab dua. Cov ntawv thov tseem ceeb suav nrog:

Kev siv tsev

  • Chav dej:Hauv chav dej, qhov twg dej thiab cov khoom siv hluav taws xob sib koom ua ke, qhov kev pheej hmoo ntawm hluav taws xob poob siab yog siab. ELCBs muab kev tiv thaiv tseem ceeb los ntawm kev txiav lub hwj chim sai sai thaum muaj dej ntws tawm.
  • Chav ua noj:Cov chav ua noj yog lwm qhov chaw muaj kev pheej hmoo siab vim muaj dej thiab cov khoom siv hluav taws xob. ELCBs pab tiv thaiv hluav taws xob thiab hluav taws xob hluav taws xob.
  • Cov cheeb tsam sab nraum zoov:Kev teeb tsa hluav taws xob sab nraum zoov, xws li vaj teeb pom kev zoo thiab cov hluav taws xob hluav taws xob, raug rau huab cua, ua rau lawv muaj kev cuam tshuam rau cov dej xau. ELCBs ua kom muaj kev nyab xeeb hauv cov cheeb tsam no.
  • Cov chaw tsim kho:Cov chaw tsim kho feem ntau muaj kev teeb tsa hluav taws xob ib ntus thiab raug mob hnyav. ELCBs tiv thaiv cov neeg ua haujlwm los ntawm hluav taws xob thiab tiv thaiv hluav taws xob hluav taws xob.
