- Txhim kho cov casing tiv thaiv
Lub underground ib puag ncig ntawm thee mines yog complex. Tsis tsuas yog muaj ntau yam khoom tsim tawm, tab sis kuj tseem muaj roj. Yog tias arcs thiab sparks raug tsim thaum lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob rau ntau yam laj thawj, hluav taws kub thiab tawg yuav tshwm sim. Cov cuab yeej tiv thaiv hu ua flameproof casing yog siv los tiv thaiv cov khoom siv hluav taws xob thiab tag nrho cov khoom siv hluav taws xob. Tom qab kev txhim kho cov flameproof casing no, lub arcs, sparks thiab explosions generated los ntawm hluav taws xob Cheebtsam los yog cov cuab yeej yuav raug cais nyob rau hauv thiab yuav tsis cuam tshuam rau sab nraud ib puag ncig thiab ib puag ncig cov khoom. Txoj kev no muaj cov ntawv thov siab nyob rau hauv cov thee mine underground motors thiab high voltage switches, thiab cov nyhuv kuj zoo.
- Siv intrinsically muaj kev nyab xeeb circuits
Intrinsically kev nyab xeeb circuits yog ib lub tswv yim tshiab ntawm kev ruaj ntseg circuits, uas feem ntau yog hais txog qhov tseeb hais tias txawm tias ib tug luv luv Circuit Court los yog spark tshwm sim thaum lub sij hawm ua hauj lwm ntawm lub Circuit Court, lub degree tsis txaus ignite los yog detonate ib puag ncig combustibles thiab combustible gases. Tam sim no, daim ntawv tshwj xeeb ntawm kev ruaj ntseg Circuit Court no tau siv dav hauv kuv lub teb chaws lub zog, textile thiab lwm yam lag luam. Intrinsically kev nyab xeeb circuits tuaj yeem ua haujlwm ruaj khov ntawm thaj chaw txaus ntshai thiab thaj chaw nyab xeeb hauv cov tshuab hluav taws xob. Cov yam ntxwv tseem ceeb ntawm kev ruaj ntseg circuits txhais tau hais tias lawv qhov tam sim no thiab qhov hluav taws xob tsis zoo yog qhov me me, yog li lawv tsim nyog rau cov ntsuas me me thiab cov kab sib txuas lus hauv cov mines.
- Siv kev ntsuas kev nyab xeeb
Txoj kev no yog hais txog kev siv cov phiaj xwm kev tiv thaiv rau cov yam ntxwv ntawm cov khoom siv hluav taws xob sib txawv thiab cov tshuab hluav taws xob hluav taws xob uas tsim cov hluav taws xob thiab lwm yam kev phom sij. Lub ntsiab tshwm sim los tiv thaiv muaj xws li luv luv Circuit Court, overheating, sparks, arcs, thiab lwm yam, thiab lub ntsiab txoj kev uas siv xws li kev txhim kho rwb thaiv tsev lub zog thiab ua hauj lwm zoo ntawm txias. Cov kev tiv thaiv kev nyab xeeb no feem ntau yog siv rau cov transformers thiab motors hauv cov mines, uas tuaj yeem txhim kho kev nyab xeeb ntawm cov khoom siv hluav taws xob nws tus kheej.
- Tsis siv neeg txiav tawm ntaus ntawv
Los ntawm kev txhim kho cov sensors ntawm qhov chaw tsim nyog ntawm cov khoom siv hluav taws xob thiab cov tshuab hluav taws xob, ib zaug luv luv Circuit Court, overheating, thiab sparks pom, lub hwj chim mov thiab Circuit Court raug txiav tawm. Qhov kom zoo dua ntawm txoj kev no yog tias nws tuaj yeem hloov tau cov ntaub ntawv ntawm lub sijhawm saib xyuas cov khoom siv hluav taws xob zoo thiab ua kom muaj txiaj ntsig zoo thaum thawj zaug muaj kev phom sij. Nyob rau hauv txoj kev no, cov khoom siv hluav taws xob feem ntau tuaj yeem raug txiav tawm ua ntej lub tshav kub thiab cov hluav taws kub hnyiab cov hmoov av thiab cov pa roj hauv ib puag ncig kom tiv thaiv qhov tshwm sim ntawm kev tawg.
