1. Nruab lub plhaub tiv thaiv
Ib puag ncig hauv av ntawm cov chaw tsuas thee yog qhov nyuaj heev. Tsis yog tsuas yog ntau yam khoom siv tsim khoom sib sau ua ke xwb, tab sis kuj tseem yuav muaj roj. Yog tias muaj arcs thiab sparks tshwm sim thaum lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob rau ntau yam laj thawj, hluav taws thiab tawg yuav tshwm sim. Ib lub cuab yeej tiv thaiv hu ua flameproof casing yog siv tshwj xeeb los tiv thaiv cov khoom siv hluav taws xob thiab tag nrho cov khoom siv hluav taws xob. Tom qab txhim kho lub flameproof casing no, cov arcs, sparks thiab tawg tsim los ntawm cov khoom siv hluav taws xob lossis cov khoom siv yuav raug cais tawm sab hauv thiab yuav tsis cuam tshuam rau ib puag ncig sab nraud thiab cov khoom siv ib puag ncig. Txoj kev no muaj tus nqi siv siab hauv cov khoom siv cav hauv av thiab cov hloov hluav taws xob siab thiab qis, thiab qhov cuam tshuam zoo heev.
2. Siv cov voj voog uas muaj kev nyab xeeb sab hauv
Cov voj voog muaj kev nyab xeeb yog lub tswv yim tshiab ntawm cov voj voog kev nyab xeeb, uas feem ntau yog hais txog qhov tseeb tias txawm tias muaj luv luv lossis hluav taws xob tshwm sim thaum lub sijhawm ua haujlwm ntawm lub voj voog, qib tsis txaus los ua rau muaj hluav taws lossis ua rau cov khoom siv hluav taws xob thiab cov pa roj uas kub hnyiab. Tam sim no, daim ntawv tshwj xeeb ntawm kev nyab xeeb no tau siv dav hauv kuv lub tebchaws lub zog, textile thiab lwm yam kev lag luam. Cov voj voog muaj kev nyab xeeb tuaj yeem ua haujlwm ruaj khov ntawm thaj chaw txaus ntshai thiab thaj chaw muaj kev nyab xeeb hauv cov kab ke hluav taws xob. Cov yam ntxwv tseem ceeb ntawm cov voj voog muaj kev nyab xeeb txhais tau tias lawv cov ntsuas tam sim no thiab voltage me me, yog li lawv tsim nyog dua rau cov cuab yeej ntsuas me me thiab cov kab sib txuas lus hauv cov chaw tsuas thee.
3. Ua cov kev ntsuas kom muaj kev nyab xeeb ntxiv
Txoj kev no hais txog kev siv cov kev tiv thaiv tshwj xeeb rau cov yam ntxwv ntawm cov khoom siv hluav taws xob sib txawv thiab cov kab ke uas tsim cov hluav taws xob thiab lwm yam kev phom sij rau kev nyab xeeb. Cov xwm txheej tseem ceeb uas yuav tsum tau tiv thaiv suav nrog luv luv circuits, overheating, sparks, arcs, thiab lwm yam, thiab cov txheej txheem tseem ceeb siv suav nrog kev txhim kho lub zog rwb thaiv tsev thiab ua haujlwm zoo ntawm kev txias. Cov kev ntsuas kev nyab xeeb no feem ntau siv rau transformers thiab motors hauv cov thee mines, uas tuaj yeem txhim kho qib kev nyab xeeb ntawm cov khoom siv hluav taws xob nws tus kheej.
4. Lub cuab yeej txiav tawm tsis siv neeg
Los ntawm kev teeb tsa cov sensors ntawm qhov chaw tsim nyog ntawm cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob, thaum pom cov hluav taws xob luv luv, kub dhau, thiab hluav taws xob, lub zog thiab lub voj voog yuav raug txiav tawm. Qhov zoo ntawm txoj kev no yog tias nws tuaj yeem hloov pauv kev saib xyuas cov khoom siv hluav taws xob tiag tiag thiab ua kev kho mob zoo thaum thawj zaug muaj kev phom sij. Ua li no, lub zog feem ntau tuaj yeem raug txiav tawm ua ntej qhov chaw kub thiab hluav taws xob ua rau cov hmoov av thee thiab roj nyob hauv ib puag ncig kom tiv thaiv kev tawg.
