Cov ntawv thov hluav taws xob siab yog qhov tseem ceeb hauv ntau yam lag luam xws li kev tsim hluav taws xob, kev tsim khoom, thiab kev sib txuas lus. Cov qhov hluav taws xob siab (HV) yog ib qho ntawm cov khoom tseem ceeb hauv cov ntawv thov no. Cov qhov hluav taws xob no tau tsim los txuas cov cables siab kom muaj kev nyab xeeb thiab ua tau zoo, tab sis lawv kuj muaj kev pheej hmoo loj yog tias tsis tuav kom raug. Tsab xov xwm no piav qhia txog cov lus qhia tseem ceeb rau kev tuav cov qhov hluav taws xob siab kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.
1. Nkag siab txog cov khoom siv
Ua ntej ua haujlwm nrogcov qhov hluav taws xob siab, nco ntsoov nkag siab txog cov khoom siv uas siv. Paub txog cov lus qhia, kev ntsuas, thiab cov txheej txheem ua haujlwm ntawm cov xov hluav taws xob siab thiab cov qhov (sockets). Cov kev paub no yuav pab koj txheeb xyuas cov kev phom sij thiab nkag siab txog cov kev ceev faj tsim nyog uas yuav tsum tau ua.
2. Siv Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
Ib txwm hnav cov khoom siv tiv thaiv tus kheej (PPE) thaum ua haujlwm nrog cov qhov hluav taws xob siab. Qhov no suav nrog cov hnab looj tes rwb thaiv tsev, cov tsom iav, lub kaus mom tawv, thiab cov khaub ncaws tiv thaiv hluav taws. PPE kom raug tuaj yeem txo qhov kev pheej hmoo ntawm kev raug hluav taws xob thiab lwm yam kev raug mob uas cuam tshuam nrog kev ua haujlwm nrog hluav taws xob siab.
3. Lub zog tua hluav taws xob
Ua ntej txuas lossis tshem tawm cov qhov hluav taws xob siab, xyuas kom tseeb tias lub kaw lus tsis muaj zog lawm. Qhov no txhais tau tias tua lub hwj chim thiab siv cov khoom siv kuaj kom raug los xyuas kom meej tias lub voj voog tsis muaj zog lawm. Tsis txhob xav tias lub voj voog tsis muaj zog lawm; ib txwm siv lub cuab yeej ntsuas hluav taws xob kom paub tseeb tias qhov no yog qhov tseeb.
4. Khaws qhov deb kom muaj kev nyab xeeb
Kev tswj kom muaj kev nrug deb yog qhov tseem ceeb thaum ua haujlwm nrog cov khoom siv hluav taws xob siab. Kev hluav taws xob siab tsim cov teb hluav taws xob uas nthuav dav dhau ntawm qhov ntau thiab tsawg ntawm cov khoom siv lub cev. Thaum lub sijhawm ua haujlwm, xyuas kom koj thiab cov neeg sawv ntawm qhov chaw nyob deb ntawm cov qhov hluav taws xob siab. Ua raws li cov lus qhia kev nyab xeeb uas tau teeb tsa kom tswj tau qhov deb tsawg kawg nkaus thiab zam kev sib cuag tsis tau xav txog.
5. Tshawb xyuas koj cov khoom siv tsis tu ncua
Yuav tsum tau kuaj xyuas cov qhov hluav taws xob high voltage thiab cov khoom siv cuam tshuam tsis tu ncua kom ntseeg tau tias muaj kev nyab xeeb. Xyuas seb puas muaj cov cim qhia tias puas tsuaj, puas tsuaj lossis xeb uas yuav cuam tshuam rau kev ruaj khov ntawm lub qhov hluav taws xob. Cov khoom puas tsuaj yuav tsum tau hloov tam sim ntawd thiab cov khoom siv yuav tsum tau tshem tawm ntawm kev siv kom txog thaum kho tiav.
6. Ua raws li cov txheej txheem xauv / tagout
Thaum ua haujlwm rau lossis nyob ze ntawm cov qhov hluav taws xob muaj zog siab, yuav tsum ua raws li cov txheej txheem lockout/tagout (LOTO). Cov txheej txheem no ua kom ntseeg tau tias cov khoom siv raug kaw kom zoo thiab tsis tuaj yeem rov ua kom muaj zog dua thaum lub sijhawm saib xyuas lossis kho. Ib txwm ua raws li koj lub koom haum cov txheej txheem LOTO kom muaj kev nyab xeeb ntxiv.
7. Siv cov cuab yeej thiab cov txheej txheem tsim nyog
Thaum siv cov qhov hluav taws xob siab, siv cov cuab yeej tsim los rau kev siv hluav taws xob siab. Cov cuab yeej rwb thaiv tsev pab tiv thaiv kev sib tsoo nrog cov khoom siv hluav taws xob. Tsis tas li ntawd, ua raws li cov txheej txheem txuas thiab txiav cov xov hlau kom raug kom txo qhov kev pheej hmoo ntawm kev arc lossis luv luv circuits.
8. Kev cob qhia thiab kev qhia cov neeg ua haujlwm
Kev cob qhia yog ib qho tseem ceeb ntawm kev nyab xeeb hauv kev siv hluav taws xob siab. Xyuas kom tseeb tias txhua tus neeg ua haujlwm koom nrog kev ua haujlwm ntawm cov chaw hluav taws xob siab tau kawm tiav hauv cov txheej txheem kev nyab xeeb, kev siv cov khoom siv, thiab cov txheej txheem teb rau thaum muaj xwm txheej ceev. Cov kev kawm rov ua dua tshiab tsis tu ncua tuaj yeem pab ua kom muaj kev nyab xeeb hauv kev ua haujlwm.
xaus lus
Ua haujlwm nrogcov hlua khi hluav taws xob siabHauv cov ntawv thov hluav taws xob siab yuav tsum nkag siab zoo txog cov txheej txheem kev nyab xeeb thiab cov kev coj ua zoo tshaj plaws. Los ntawm kev ua raws li cov lus qhia kev nyab xeeb no, cov neeg ua haujlwm tuaj yeem txo qhov kev pheej hmoo ntawm kev ua haujlwm hluav taws xob siab. Kev muab kev nyab xeeb tso ua ntej tsis yog tsuas yog tiv thaiv kev nyab xeeb ntawm tus kheej xwb, tab sis kuj ua kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm tau zoo ntawm cov kab ke hluav taws xob siab. Nco ntsoov tias kev nyab xeeb yog lub luag haujlwm sib koom thiab nws yog qhov tseem ceeb kom ceev faj hauv cov chaw muaj hluav taws xob siab.
