Lubchav tsev neeg siv khoomyog ib qho ntawm cov khoom tseem ceeb ntawm kev teeb tsa hluav taws xob hauv tsev nyob lossis tsev lag luam. Nws muaj lub qhov hloov pauv tseem ceeb, fuses thiab circuit breakers thiab tswj kev faib hluav taws xob thoob plaws hauv thaj chaw. Hauv tsab xov xwm no, peb yuav kawm tob dua txog qhov tseem ceeb ntawm cov khoom siv hluav taws xob thiab tham txog lawv cov haujlwm thiab cov yam ntxwv.
Lub hom phiaj tseem ceeb ntawm lub tshuab no yog los tiv thaiv lub voj voog kom tsis txhob muaj hluav taws xob ntau dhau thiab luv luv. Nws ua haujlwm ua ib qho kev thaiv kev nyab xeeb ntawm lub zog hluav taws xob nkag los thiab ntau yam khoom siv hauv lub tsev. Yog tsis muaj cov khoom siv hluav taws xob, qhov kev pheej hmoo ntawm kev raug mob hluav taws xob xws li hluav taws thiab hluav taws xob poob siab yuav nce ntxiv heev.
Cov khoom siv hluav taws xob muaj ntau hom thiab ntau qhov loj sib txawv nyob ntawm qhov xav tau ntawm kev teeb tsa hluav taws xob. Hom feem ntau hu ua lub thawv fuse ib txwm muaj, qhov twg ntau lub fuses tiv thaiv txhua lub voj voog. Txawm li cas los xij, cov khoom siv niaj hnub no feem ntau muaj cov circuit breakers, uas ua haujlwm tau zoo dua thiab muab kev tiv thaiv zoo dua.
Ib qho ntawm cov haujlwm tseem ceeb ntawm lub tshuab them nqi yog lub qhov hloov pauv loj. Lub qhov hloov pauv no tso cai rau koj tua hluav taws xob rau tag nrho cov chaw thaum muaj xwm txheej ceev lossis thaum xav tau kev saib xyuas. Lub qhov hloov pauv loj yuav tsum yooj yim nkag mus, yog li nws feem ntau nyob rau hauv thaj chaw pom tseeb thiab yooj yim nkag mus, xws li ze ntawm qhov nkag lossis hauv chav siv hluav taws xob.
Hauv chav tsev siv hluav taws xob, muaj cov voj voog sib cais uas faib hluav taws xob mus rau ntau qhov chaw ntawm lub tsev. Cov voj voog no muaj kev tiv thaiv los ntawm cov fuses lossis circuit breakers uas tau tsim los qhib lub voj voog thaum muaj kev thauj khoom ntau dhau lossis luv luv. Qhov no tiv thaiv kev puas tsuaj rau cov khoom siv thiab cov khoom siv txuas nrog lub voj voog, ua kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg nyob hauv.
Lwm yam tseem ceeb ntawm cov khoom siv niaj hnub no yog lub cuab yeej hluav taws xob seem (RCD). RCD yog ib lub cuab yeej kev nyab xeeb uas sai sai nrhiav tau qhov tsis sib npaug ntawm cov hluav taws xob, xws li thaum ib tug neeg kov cov xov hlau uas muaj hluav taws xob. Tom qab ntawd nws yuav txiav lub zog, tiv thaiv kev poob hluav taws xob thiab tej zaum yuav cawm tau txoj sia. RCDs tau dhau los ua qhov yuav tsum muaj rau feem ntau ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj dej xws li chav ua noj thiab chav dej.
Nyob rau hauv xyoo tas los no, cov khoom siv rau cov neeg siv khoom kuj tau hloov zuj zus los suav nrog cov yam ntxwv ntxiv, xws li kev tiv thaiv hluav taws xob.Cov khoom siv tiv thaiv hluav taws xob ntau dhau (SPDs)pab tiv thaiv cov khoom siv los ntawm kev nce hluav taws xob los ntawm xob laim lossis hluav taws xob nce siab. Los ntawm kev teeb tsa SPDs hauv cov khoom siv rau cov neeg siv khoom, koj tuaj yeem tiv thaiv koj cov khoom siv hluav taws xob muaj nqis xws li TV, khoos phis tawj thiab cov khoom siv hauv tsev los ntawm kev puas tsuaj.
Hais yooj yim xwb, cov khoom siv hluav taws xob yog ib feem tseem ceeb ntawm txhua qhov kev teeb tsa hluav taws xob. Nws ua kom muaj kev nyab xeeb ntawm hluav taws xob thoob plaws hauv lub tsev, tiv thaiv cov voj voog thiab cov neeg hauv lub tsev. Thaum xaiv cov khoom siv rau cov neeg siv khoom, nws yog ib qho tseem ceeb uas yuav tsum xaiv ib qho uas ua tau raws li cov kev cai tshwj xeeb ntawm koj lub tshuab hluav taws xob thiab ua raws li cov qauv kev nyab xeeb. Kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv rau cov neeg siv khoom kuj tseem ceeb heev kom ntseeg tau tias lawv ua haujlwm tau zoo thiab muaj kev nyab xeeb.
