Cov hnab looj tes Dielectric tiv thaiv tes los ntawm hluav taws xob. Los ntawm cov khoom siv ntawm tsab xov xwm no, koj yuav kawm paub tias cov yam ntxwv zoo li cas muaj ntau yam, xaiv thiab siv lawv li cas.
Peculiarities
Cov hnab looj tes dielectric seamless yog ib feem ntawm cov khoom siv hluav taws xob. Lawv tau siv thaum ua haujlwm nrog cov khoom siv hluav taws xob thiab cov xov hluav taws xob. Cov cuab yeej tiv thaiv xav tau thaum koj xav tau:
- disconnect / txuas lub pantograph nrog qhov hluav taws xob ntau dua 800 V;
- hloov qhov hluav taws xob qhov hluav taws xob siab;
- hloov lub teeb pom kev zoo;
- disconnect lub terminals ntawm lub transformer;
- ua haujlwm nrog lub thim rov qab lub ntsiab lus.
Cov hnab looj tes uas tsis muaj dielectric ua kom muaj kev nyab xeeb ntawm cov kws kho hluav taws xob muab kev teeb tsa hluav taws xob, kab hluav taws xob, cov khoom siv hluav taws xob.
Ntxiv mus, nyob ntawm ntau yam, lawv tuaj yeem dhau los ua kev tiv thaiv ntxiv yog tias qhov hluav taws xob ntau dua 1000 V.
Yog tias lawv loj me me kom haum, lawv khaws lawv cov kev paub siv tas nrho.
Cov PPE no raug raws li qhov xav tau kev nyab xeeb . Cov hnab looj tes ua los ntawm cov txheej txheem ntawm kev sib khi tsis xeb yog qhov yooj yim los ua haujlwm nrog. Lawv tau siv los ntawm cov kws tshaj lij, ua haujlwm ntawm qib sib txawv ntawm qhov nyuaj. Cov khoom lag luam me me, txawm li cas los xij, qhov kev xaiv xav tau kev saib xyuas tshwj xeeb. Qhov yuam kev me me tuaj yeem ua rau raug mob vim hluav taws xob.
Cov hnab looj tes dielectric raug kuaj ob zaug hauv ib xyoos . Qhov kev sim no tau ua nyob hauv chav kuaj mob raws li qhov tshwj xeeb. Nyob rau tib lub sijhawm, cov ntim tshwj xeeb nrog kua tau siv, muab cov hnab looj tes tso rau hauv kom lawv tsis tsuas yog sab nraud, tab sis kuj sab hauv. Ntxiv mus, txoj kab ncaj ncaj ntug ntawm txhua khub yuav tsum tsis txhob raus dej hauv qhov tsawg kawg 5 hli. Hauv ib feeb, qhov hluav taws xob ntawm 6 kV tau siv.
Hauv qhov no, qhov xau tam sim no yuav tsum tsis pub tshaj 6 mA. Tom qab qhov kev sim, cov hnab looj tes tau qhuav hauv chav tshwj xeeb, tom qab ntawd lawv tau thwj cim nrog qhov qhia txog lub sijhawm siv mus txog thaum kuaj xyuas tom ntej . Qhov nruab nrab, tus nqi ntsuas ib khub tuaj yeem yog 195 rubles, muab tias nws tau ua tiav hauv 5 hnub. Yog tias koj xav tau, koj tuaj yeem tshawb xyuas tus khub hauv 1 hnub los ntawm kev them nyiaj 295 rubles.
Ntau yam
Cov hnab looj tes uas tsis muaj dielectric tuaj yeem raug cais raws li ob yam: cov khoom siv tsim khoom thiab tus naj npawb ntawm cov ntiv tes. Cov cuab yeej tiv thaiv tus kheej yog tsim los ntawm cov khoom siv sib xyaw roj hmab (ntawv roj hmab lossis yas). Ua tsaug rau kev siv cov khoom siv ntuj tsim, cov khoom lag luam tsis ua rau tawv nqaij ntawm txhais tes thiab tsis ua rau muaj kev fab tshuaj.
Cov hnab looj tes yas thiab roj hmab dielectric muaj ntau qhov sib txawv . Nws tau xaiv hauv txoj hauv kev uas nws nyiam ua haujlwm nrog hnab looj tes.
Cov qauv rau kev ua haujlwm ntawm subzero kub tau dav dua.
Qhov no ua tiav kom lub tsho (piv txwv li, knitted leggings lossis lub tsho sov sov) tuaj yeem hnav hauv qab hnab looj tes.
Raws li tus naj npawb ntawm cov ntiv tes, cov khoom lag luam yog ib txwm muaj tsib ntiv taw thiab ob-ntiv taw . Kev xaiv ntawm hom thib ob tsis yooj yim dua, tsib tus ntiv tes tsis txwv tus neeg siv txoj haujlwm. Thaum xaiv ib lossis lwm qhov kev xaiv, ib tus yuav tsum tsis txhob hnov qab txog qib qhov hluav taws xob. Raws li qhov no, cov khoom lag luam tau muab faib ua 2 pawg: "Ev" thiab "En".
Raws li GOST 12.4.103-83, tus cim "En" qhia tias cov khoom tuaj yeem siv los ua kev tiv thaiv tiv thaiv tam sim no ntawm qhov hluav taws xob mus txog 1000 V . Lub cim "Ev" qhia tias hnab looj tes tsim nyog raws li cov cuab yeej tiv thaiv ntxiv rau kev teeb tsa nrog qhov hluav taws xob ntau dua 1 kV. Nyob rau tib lub sijhawm, lawv tau siv nrog hluav taws xob insulating tongs thiab pas nrig.
Yuav xaiv li cas?
Muaj ntau qhov txheej txheem tseem ceeb los txiav txim siab thaum xaiv cov hnab looj tes dielectric. Piv txwv li, cov khoom siv roj hmab zoo rau kev ua haujlwm nrog hluav taws xob ntau txog 1000 V thiab ntau dua 1 kV muaj 2 txheej sib txawv ntawm qhov ntxoov ntxoo. Cov zauv cim nyob sab nraud ntawm lawv.
Raws li GOST cov qauv, cov hnab looj tes dielectric yog ib txwm muaj, ntxiv rau tsim los rau tshwj xeeb tshaj yog muag lossis, sib tham, ua haujlwm nyuaj . PPE tsis yog thoob ntiaj teb: koj yuav tsum yuav cov khoom lag luam uas haum rau lub hom phiaj. Piv txwv li, cov khoom npaj rau kev ua haujlwm ntxhib yuav tsum muaj phab ntsa tuab txog li 9 hli. Analogues rau kev ua haujlwm zoo yuav tsum tsis txhob tuab dua 4 hli.
Koj yuav tsum yuav cov qauv uas leggings tuaj yeem yooj yim muab tso rau hauv sov lossis knitted mittens.
Qhov ntev tshaj plaws ntawm cov hnab looj tes dielectric yuav tsum yog yam tsawg 35 cm (ntsuas los ntawm qhov taub ntawm tus ntiv tes ntsuas mus rau ntug ntawm cov khoom).
Nws yog ib qho tseem ceeb yuav cov khoom lag luam hauv qhov loj me, coj mus rau hauv tus account cov hnab looj tes lossis hnab looj tes hnav hauv qab lawv . PPE uas loj dhau tuaj yeem cuam tshuam rau tus neeg siv txoj haujlwm.
Raws li rau hom khoom, txhua yam nws nyob ntawm lub hom phiaj . Qee zaum ob-ntiv taw ntau yam tuaj yeem siv rau kev ua haujlwm. Thaum ua cov haujlwm yooj yim, ib tus tsis tuaj yeem ua yam tsis hloov kho ntawm tsib-ntiv tes hom. Thaum xaiv koj qhov kev xaiv, koj yuav tsum tau them sai sai rau qhov ua tau zoo. Cov khub saib xyuas yuav tsum tsis muaj cov seem seem ntawm kev tsim khoom (piv txwv li, nthuav tawm cov roj hmab sib txuas, nrog rau lwm yam tsis xws luag).
Cov ntsiab lus ntawm kev siv
Tsuas yog cov hnab looj tes uas tau thwj nrog daim ntawv qhia kev xeem tshwj xeeb tuaj yeem siv tau. Hauv qhov no, cov khoom lag luam yuav tsum tsis txhob muaj cov khoom puas. Tsis txhob siv PPE ntub lossis qias neeg . Ua ntej pib ua haujlwm, koj yuav tsum txheeb xyuas cov khoom kom raug lossis tawg. Txog qhov no, hnab looj tes tau muab tso rau ntawm qhov tiaj tiaj thiab sib tw ntawm cov ntiv tes.
Hnab looj tes yuav tsum tau tshuaj xyuas ua ntej txhua qhov siv . Yog tias txhua yam tau ua tiav, lawv tuaj yeem siv tau rau rau lub hlis txij li hnub tshuaj xyuas, tom qab ntawd lawv yuav tsum rov xeem dua. Yog tias qhov kev tshuaj xyuas qhia pom qhov tawg lossis qhov txhab, cov hnab looj tes yuav tsum tau hloov nrog cov tshiab.
Cov looj hnab looj tes tuaj yeem hnav los tiv thaiv hnab looj tes .… Thaum ua haujlwm, yuav tsum tau saib xyuas kom tsis txhob qhwv cov npoo ntawm hnab looj tes. Qhov no cuam tshuam rau tus neeg siv kev nyab xeeb. Tsis txhob txhuam cov hnab looj tes nrog koj lub qhov ncauj, qhov no yuav ua rau lawv ntub.
Kev tua kab mob tsis tuaj yeem tsis quav ntsej ib qho twg, uas yog siv cov tshuaj tov dej qab zib lossis xab npum . Hnab looj tes yuav tsum hnav tshaj khaub ncaws. Thaum ua haujlwm ze rau ntawm cov npoo ntse, hnab looj tes tawv yuav tsum hnav dua cov hnab looj tes dielectric.
Txoj cai khaws cia tsis tuaj yeem tsis quav ntsej . Roj hmab degrades thaum raug tshav kub, roj av, roj av ntxhia, ultraviolet rays thiab alkali daws. Khaws cov khoom kom deb ntawm cov khoom siv cua sov thiab lub tshuab hluav taws xob, tsis txhob hnov qab txog qib zoo ntawm cov av noo. Tsis txhob khaws hnab looj tes nyob rau hauv tshav ntuj ncaj qha.
