Dielectric galoshes tsis yog lub hauv paus, tab sis pab txhais tau tias tiv thaiv siv thaum ua haujlwm ntawm kev teeb tsa hluav taws xob. Kev siv cov khau zoo li no tuaj yeem ua tau tsuas yog nyob hauv huab cua ntshiab, thaum tsis muaj nag lossis daus.

Peculiarities

Hluav taws xob insulating (dielectric) galoshes feem ntau siv rau kev ua haujlwm ntawm kev teeb tsa hluav taws xob, tab sis lawv kuj muaj lwm lub hom phiaj - siv hauv tsev. Cov khau zoo li no muab kev tiv thaiv tsim nyog tiv thaiv hluav taws xob siab txog 20 kV rau 3 feeb . (qhov ua haujlwm siab tshaj plaws yog 17 kV). Vulcanized roj hmab outsole tiv taus cov roj thiab roj, lub sijhawm tiv tshav kub kub (txog 300 ° C tuaj yeem tiv tauj tau 1 feeb).

Cov khoom muaj cov khoom tiv thaiv zoo heev, tiv thaiv kev txiav kom ntau thiab lub zog nqus hauv thaj chaw pob taws.

Galoshes yog ib qho yooj yim muab tso rau thiab nrawm, thiab yooj yim rau fasten . Siv ua ke nrog lwm cov cuab yeej xav tau, lawv nce kev nyab xeeb ntawm kev ua haujlwm. Lawv tau ua los ntawm cov roj hmab feem pua siab raws cov roj hmab ntuj. Lawv muaj lub neej txee ntev txog 12 lub hlis txij li hnub tsim khoom.

Qee cov qauv muaj cov ntaub xaws hauv sab hauv kom zoo dua lub zog tsim kua muag. Qhov tiv thaiv plam ib leeg tuaj yeem siab txog 10 hli. Cov cuab yeej tiv thaiv no txawv ntawm nws cov xim ci.

Qhov taw qhia taw qhia rau khau dielectric ntawm hom piav qhia yog qhov xau tam sim no tsis tshaj 2.5 mA.

Cov khoom muaj monolithic ib leeg nrog cov nplaim nplaim . Raws li kev nyab xeeb xav tau, nws raug txwv tsis pub suav nrog cov khoom txawv teb chaws hauv kev tsim cov galoshes. Ua ntej siv, txhua tus khub yuav tsum tau tshuaj xyuas rau delamination, delamination, tawg, vim lawv ua rau kev puas tsuaj ntawm kev ncaj ncees ntawm txheej insulating.

Cov khoom siv los ntawm cov khoom lag luam tau tsim ua tau raws li qhov yuav tsum tau ua ntawm kev nyab xeeb thiab tiv thaiv kev ua haujlwm, nws tsis tuaj yeem lees txais suav nrog tshuaj lom, tshuaj lom tawg hauv qhov sib xyaw ntawm cov khoom, nrog rau cov uas muaj cov yam ntxwv hluav taws xob.

Thaum nyob rau hauv kev sib cuag nrog lub ntsej muag uas tshwj xeeb yog txhoj puab heev, galoshes yuav tsum tsis txhob tso cov tshuaj lom neeg, tshuaj lom neeg thiab tshuaj lom . Lub xub ntiag ntawm kev tiv thaiv tshwj xeeb tuaj yeem hais los ntawm cov cim ntawm khau. Nws tuaj yeem yog "En" lossis "Ev".

Tsis thiab qhov ntev

Hauv cov lus ntawm lub tsev tsim khoom rau dielectric galoshes, qhov ntsuas tau siv: 300, 307, 315, 322, 330, 337, 345. GOST kuj tseem siv rau hauv qhov loj me txav mus los, yog li, nws tsis tshua muaj, tab sis koj tuaj yeem pom cov khau cim 292 thiab 352 ntawm kev ua lag luam. Tseeb tiag, cov qauv no tsis muaj tab sis tuaj yeem xaj los ntawm lub hoobkas. Dielectric galoshes ib txwm muaj xim zoo nkauj, uas txawv lawv los ntawm cov qauv zoo sib xws siv hauv kev ua liaj ua teb.

Lawv muaj peev xwm tiv taus txog li 1000 V.

Qhov sib npaug sib npaug tuaj yeem yog: 40, 41, 42, 43, 44, 45, 46. Thaum xaiv ib khub, cov hauv qab no yuav tsum raug coj mus rau hauv tus account:

• ncej dav;
• qhov siab.

Cov yam ntxwv xav tau muaj nyob hauv GOST 13385-78. Txiv neej lub galoshes muaj qhov loj me ntawm 240 txog 307. Cov poj niam khau pib ntawm 225 (txog 255).

Xeem

Ua ntej siv dielectric galoshes, lawv yuav tsum tau kuaj xyuas qhov tsis xws luag. Yog tias qhov kev tshem tawm tshwm ntawm qhov chaw, tawg ntawm lub ncoo thiab lub hauv caug, sib txawv ntawm cov nqaws, cov leej faj tau tawm los, tom qab ntawd cov khoom siv tsis tau. Lub txee lub neej ntawm cov roj hmab galoshes tau hais los ntawm cov chaw tsim khoom thiab feem ntau yog ib xyoos txij li hnub tsim khoom thiab ib xyoos thiab ib nrab nyob rau hauv cov xwm txheej ntawm kev siv hauv Far North.

Lawv yuav tsum tau kuaj ib ntus ntawm lub tuam txhab nrog qhov hluav taws xob. Qhov zaus ntawm qhov kev tshuaj xyuas no yog tsim los ntawm cov cai tswj hwm.

Tom qab ua tiav txoj haujlwm, galoshes raug ntxuav thiab qhuav kom zoo. Raws li kev nyab xeeb xav tau, yuav tsum muaj ob peb khub khau roj hmab ntawm ntau qhov sib txawv nyob ze txhua qhov kev teeb tsa hluav taws xob . Nws yog ib qho tseem ceeb los tshuaj xyuas lub xub ntiag ntawm daim ntawv txheeb xyuas zaum kawg ua ntej siv. Qhov kev ntsuas tau ua tiav peb zaug txhua xyoo, nrog rau qhov ntsuas hluav taws xob ntawm 3.5 kV. Lub sij hawm raug yog 1 feeb. Nws yog qhov zoo tshaj yog tias khau tau tshuaj xyuas txhua lub sijhawm lawv tau siv.

Yog tias muaj kev puas tsuaj tshwm sim, tom qab ntawd daim tshev ua tiav tsis tau teem sijhawm . Nws yuav tsum tau ua tiav tsuas yog cov kws tshaj lij uas tsim nyog uas muaj daim ntawv pov thawj tsim nyog hauv lawv txhais tes. Ua ntej kuaj xyuas, txheeb xyuas qhov ncaj ncees ntawm qhov rwb thaiv tsev, nrog rau lub xub ntiag ntawm lub Hoobkas cim. Yog tias tus qauv tsis tau raws li qhov yuav tsum tau ua, tom qab ntawv qhov kev kuaj xyuas tsis tuaj yeem ua kom txog thaum qhov ua tsis tau raug tshem tawm.

Ib qho hluav taws xob tam sim no dhau los ntawm cov khoom txhawm rau ntsuas qhov xau tam sim no . Galoshes tau muab tso rau hauv lub taub ntim nrog dej sov. Hauv qhov no, cov npoo yuav tsum yog saum cov dej, vim tias qhov chaw sab hauv yuav tsum qhuav. Cov dej theem yuav tsum yog 2 centimeters qis dua ntawm ntug khau. Ib qho hluav taws xob tau muab tso rau sab hauv. Nws, nyeg, yog hauv av siv lub milliammeter. Qhov hluav taws xob tau tuav txog li ob feeb, nce nws mus rau qib 5 kV. Kev nyeem ntawv tau siv 30 vib nas this ua ntej qhov kev xeem tas.

Yuav siv li cas?

Kev ua haujlwm ntawm galoshes tsuas yog ua tau thaum huab cua qhuav. Cov khau yuav tsum tau khaws kom huv thiab huv si, tsis txhob tawg lossis lwm yam puas tsuaj. Cov khau tuaj yeem siv sab nraum zoov thiab hauv chav uas muaj huab cua kub xws li -30 ° C txog + 50 ° C. Galoshes tau muab tso rau lwm cov khau, thaum nws yuav tsum qhuav thiab huv . Nws raug nquahu kom paub tseeb tias tsis muaj cov ntsiab lus ntawm ib leeg uas tuaj yeem ua rau cov khoom puas.

Yuav khaws cia li cas?

Yog tias khau ruaj ntseg tsis khaws cia kom raug, lawv yuav tsis ua lawv lub luag haujlwm tseem ceeb. Rau dielectric overshoes, chav qhuav, tsaus nti tau siv, qhov twg huab cua sov siab dua 0 ° C. Cov khoom siv roj hmab tsis zoo yog tias qhov kub siab tshaj + 20 ° C.

Nkawm khau tau muab tso rau ntawm cov ntoo, cov av noo sib xws yuav tsum yog yam tsawg 50% thiab tsis ntau dua 70%.

Nws yog txwv tsis pub muab tso rau hom khau kev nyab xeeb no nyob ib puag ncig ntawm lub tshuab cua sov.

Qhov nrug yuav tsum yog yam tsawg 1 meter. Tib yam siv rau kev tshaj tawm xov xwm, suav nrog cov kua qaub, alkalis, cov txheej txheem roj. Ib qho ntawm cov tshuaj no, yog tias lawv nkag rau ntawm cov roj hmab, ua rau cov khoom puas.
