Thib peb, Scope ntawm daim ntawv thov
Hluav taws xob cov khau yog cov khoom tiv thaiv kev ua haujlwm ntawm tus kheej uas ua haujlwm pabcuam kev nyab xeeb thaum ua haujlwm ntawm cov khoom siv hluav taws xob. Lawv tsim nyog siv los ntawm cov neeg ua haujlwm hauv chaw ua haujlwm uas xav tau kev sib cuag hluav taws xob, xws li cov neeg ua haujlwm hauv kev lag luam hluav taws xob thiab cov khoom siv hluav taws xob tu cov neeg ua haujlwm.
1. Raws li cov kev cai ntawm DL408-1991, DL409-1991 thiab GB26860-2011, hluav taws xob insulating khau thiab hluav taws xob insulating daim ntaub khau thiab tag nrho cov roj hmab khau looj plab hlaub thiab kuaj khau nrog ntsuas voltage ntawm 15kV thiab Hauv qab no yog tsim rau lub zog zaus hauv qab 1000V. Hauv qhov chaw ua haujlwm; tag nrho cov khau roj hmab thiab tag nrho-polymeric khau looj plab hlaub ntawm 15kV lossis siab dua yog tsim rau kev ua haujlwm ib puag ncig siab dua 1000V.
2. Kev lag luam fais fab siv tag nrho cov roj hmab khau boots thiab tag nrho-polymeric khau looj plab hlaub nrog lub thickness ntawm 15kV los yog ntau tshaj.
3. Siv tag nrho cov khoom siv roj hmab khau boots thiab tag nrho cov-polymeric khoom khau boots nyob rau hauv mine.
4. Hluav taws xob rwb thaiv tsev tawv khau thiab hluav taws xob insulating daim ntaub roj hmab khau yog tsim rau siv nyob rau hauv ib qho chaw qhuav, tsis haum rau sab nraum zoov, ntub dej thiab lwm qhov chaw ua hauj lwm nyob rau hauv rainy huab cua.
Plaub, teeb meem xav tau kev saib xyuas
1. Ua ntej siv, xyuas seb cov cim ntawm cov hluav taws xob rwb thaiv tsev khau puas ua tiav thiab ua tau raws li tus qauv yuav tsum tau ua. Cov ntsiab lus ntawm cov paib muaj xws li:
(1) Nyob rau sab sauv lossis ib sab ntawm txhua lub khau hluav taws xob, yuav tsum muaj cov khau loj, tus lej qauv, hom hluav taws xob rwb thaiv tsev (lossis Askiv EH), lub cim hluav taws xob thiab tiv taus qhov ntsuas hluav taws xob.
(2) Tus neeg tsim khoom lub npe, tus naj npawb ntawm cov khau, cov khoom lossis cov npe khoom, hnub tsim khoom, thiab kev ua haujlwm ntawm hluav taws xob rwb thaiv tsev.
2. Thaum siv hluav taws xob rwb thaiv tsev khau thiab hluav taws xob rwb thaiv tsev khau khau, ua rau sab sauv hauv qhov chaw ua haujlwm. Qhov twg muaj corrosion los yog kev puas tsuaj rau hauv qab, nws tsis tuaj yeem hnav nrog cov khau hluav taws xob insulated.
3. Cov khau hluav taws xob insulated yuav tsum tsis txhob ntub. Nws yog txwv tsis pub siv tom qab damp. Thaum damp, nws yuav tsum tau muab tso rau hauv qhov chaw ventilated thiab txias kom qhuav ib txwm.
4. Thaum hnav cov khau hluav taws xob rwb thaiv tsev, tsis txhob sib cuag nrog cov ntse ntse, qhov kub thiab txias thiab cov khoom corrosive los tiv thaiv cov khau ntawm kev puas tsuaj thiab cuam tshuam rau lawv cov rwb thaiv tsev.
5. Cov khau hluav taws xob rwb thaiv tsev yuav tsum muab cia rau hauv qhov chaw qhuav thiab qhov cua kom tsis txhob muaj pwm thiab tsis txhob muaj roj, kua qaub lossis alkali lossis lwm yam khoom siv corrosive.
6. Txij li hnub tsim khoom, kev siv thiab khaws cia ntawm cov khau hluav taws xob rwb thaiv tsev yog 24 lub hlis. Cov khau hluav taws xob rwb thaiv tsev tshaj lub sijhawm txwv yuav tsum raug kuaj xyuas ib qho los ntawm ib qho, thiab tsuas yog siv tau tom qab dhau qhov kev xeem.
7. Raws li ib txwm muaj, cov khau hluav taws xob rwb thaiv tsev yuav tsum tau sim ib zaug txhua 6 lub hlis, thiab tsuas yog siv tau tom qab dhau qhov kev xeem. Yog tias nws tsis ua raws li tus qauv yuav tsum tau ua, nws yuav tsum tsis txhob siv cov khau hluav taws xob rwb thaiv tsev.
