Kev nyab xeeb hauv kev lag luam hluav taws xob yog qhov tseem ceeb ntawm kev ua haujlwm ntawm tag nrho lub zog hluav taws xob. Qhov no tsis yog hais txog kev tswj hwm, tab sis hais txog kev tiv thaiv tiag tiag ntawm cov neeg ua haujlwm, uas cawm tib neeg txoj sia. Raws li cov ntaub ntawv tswj hwm, txhua txoj kev tiv thaiv tau muab faib ua qhov yooj yim thiab ntxiv.

Nyob rau tib lub sijhawm, pab pawg thib ob tsis muaj qhov qis dua rau thawj zaug, pab kom tsis txhob muaj teeb meem, dhau los ua tus cawm seej thaum ua haujlwm hauv kev teeb tsa hluav taws xob nrog ntau dua 1,000 V. Hauv kab lus, cia peb tham txog dielectric bots: nws yog dab tsi, tus qauv tswj tau zoo thiab thaum twg cov cuab yeej tiv thaiv yuav tsum tau sim.

Dab tsi yog dielectric khau boots thiab overshoes?

Dielectric khau boots yog tus kheej txhais tau tias tiv thaiv kev ua haujlwm thiab kev ua haujlwm thiab kev saib xyuas cov neeg ua haujlwm los ntawm hluav taws xob poob. Ua ntej tshaj plaws, xws li cov khoom tso cai rau koj kom tsis txhob muaj cov kauj ruam voltage uas tshwm sim hauv tes hauj lwm thiabcais nruab nrab, nrog rau vim luv luv Circuit Court thaum hloov. Ib rooj plaub cais tuaj yeem suav hais tias yog qhov kev siv ntawm qhov nce siab ntawm lub zog hluav taws xob siab ntawm txoj kab hloov pauv.

Kev tsim cov khau tshwj xeeb tuaj yeem ua tau los ntawm lub tuam txhab uas muaj daim ntawv tso cai tsim nyog, thiab nws cov khoom ua raws li lub xeev cov qauv lossis cov lus qhia tshwj xeeb. Sab nraud, cov khoom muaj ib qho zoo li ib qho, muaj cov roj hmab tuab. Lub outsole yog grooved rau traction zoo.

Kev siv cov cuab yeej tiv thaiv yog nyob ntawm kev ua haujlwm thiab cov xwm txheej uas nws yuav ua. Raws li cov lus qhia thiab STP ntawm kev nyab xeeb, dielectric khau looj plab hlaub yog siv hauv cov xwm txheej hauv qab no:

1. Kev ua haujlwm hloov pauv hauv qhib thiab kaw switchgears.
2. Kev ua kom muaj zog tuaj yeem ua rau luv luv rau hauv av los ntawm cov av electrode, qhov tshwm sim ntawm cov kauj ruam voltage.
3. Thaum ib-theem luv luv rau lub ntiaj teb nyob rau hauv kev sib cais nruab nrab. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev siv cov khau yuav tsum muaj nyob rau txhua qhov, txawm tias muaj xwm txheej ceev ntawm VL-10, 35 kV.

Raws li qhov ua tau zoo, cov ntaub ntawv tau muab hauv GOST 13385-78.

xeev Standards

Dielectric khau raj raws li GOST 13385-78 raug hu ua "Tshwj xeeb dielectric khau ua los ntawm cov ntaub ntawv polymeric". Cov ntaub ntawv sau tawm cov haujlwm tseem ceeb hais txog cov duab, qhov loj ntawm cov khoom, lawv yog dab tsi thiab dab tsixeem cov qauv yuav tsum tau ua. Cov tom kawg yog suav tias yog lub hauv paus rau kev ua haujlwm tau zoo thiab kev tiv thaiv cov neeg ua haujlwm los ntawm qhov hluav taws xob siab.

Tests

Cov txheej txheem ntawm kev sim dielectric khau looj plab yuav luag tag nrho sib haum nrog cov hnab looj tes. Txhawm rau ua qhov no, khau tau muab tso rau hauv lub nkoj tshwj xeeb nrog dej, uas tau muab hluav taws xob txog li 20 kV. Cov txheej txheem yuav siv li 2 feeb. Nws raug tso cai ua haujlwm nrog ntau yam khoom ib zaug. Yog hais tias ib yam khoom ua tsis tau qhov kev xeem, nws yog stamped nrog ib tug liab indelible number case.

Thaum muab tso rau hauv kev ua haujlwm, bots yuav tsum tau kuaj xyuas txhua 2 xyoos. Hauv qee lub koom haum, lub sijhawm xa tawm raug txo los ntawm kev txiav txim lossis lwm cov ntaub ntawv tswj hwm kos npe los ntawm tus kws tshaj lij.

Kev nyab xeeb

Dielectric khau boots yuav tsum tsis yog tsuas yog yuav tsum tau kuaj, tab sis kuj yuav tsum tau ua raws li teem sijhawm soj ntsuam. Raws li cov ntaub ntawv tswj hwm, cov thawj coj thiab cov neeg ua haujlwm yuav tsum tau koom nrog hauv cov haujlwm no - ib hlis ib zaug, cov khoom yuav tsum tau kuaj xyuas cov khoom puas tsuaj. Tsis tas li ntawd, ua ntej txhua qhov kev siv, lawv raug kuaj los ntawm cov neeg ua haujlwm thiab kho cov neeg ua haujlwm. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev hnav khau ntawm qhov chaw mus tas li yog qhov tsis tsim nyog. Nws yuav tsum hnav tsuas yog nyob rau hauv rooj plaub uas tau piav qhia hauv cov cai TB.
