Txawm tias sab nrauv sheath ntawmkabthiab cov ntaub qhwv sab hauv muaj qee yam rwb thaiv tsev, tab sis txhawm rau tiv thaiv kev puas tsuaj ntawm cov khoom siv los ntawm luv luv Circuit Court ntawm cov hlau raug, thiab kev puas tsuaj ntawm cov xaim dhau ntawm qhov kev nyab xeeb voltage yuav tsum tau ntxiv rau cov kab hluav taws xob tiv thaiv txheej. Lub luag haujlwm tseem ceeb ntawm txheej txheej rwb thaiv tsev yog txhawm rau tiv thaiv tus neeg xyuas pib hauv cable los ntawm ib puag ncig ib puag ncig lossis los ntawm ib leeg ntawm cov neeg nyob ib sab.
Ntau qhov tsis tsim nyog cables tso tawm los ntawm General Administration of Quality Supervision of the State los yog lub chaw saib xyuas hauv zos yog qhov tsis tsim nyog. Hauv kev tshaj tawm ntawm ntau tus neeg xa khoom tawm los ntawm Lub Xeev Grid, peb tuaj yeem pom cov ntawv ceeb toom zoo li no los ntawm cov tuam txhab cable: cov txheej txheem rwb thaiv tsev tuab ntawm lub hwj chim cable tsim tsis tsim nyog. Tom qab ntawd dab tsi yog qhov cuam tshuam ntawm qhov tsis tsim nyog rwb thaiv tsev thickness ntawm lub cable?
Nws yuav ua rau lub neej luv luv ntawm cov khoom siv hlau thiab cable. Tom qab ua haujlwm ntev, tshwj xeeb tshaj yog nyob rau hauv ncaj qha faus, dej nyab, qhib huab cua lossis corrosive ib puag ncig, cov txheej txheem rwb thaiv tsev thiab cov txheej txheem txheej txheem ntawm cov sheath nyias yuav raug txo vim yog lub sij hawm ntev corrosion ntawm sab nraud nruab nrab. Tsis tas li ntawd, kev kuaj lub tsho niaj hnub lossis kab hauv av ua txhaum yuav ua rau nyias nyem-dhau. Qhov no yuav plam qhov kev tiv thaiv ntawm cable sheath. Kev siv sab hauv tsis tuaj yeem tsis quav ntsej. Cov kab hluav taws xob nyob thiab cov kab hluav taws xob tsim hluav taws xob ntau. Qhov kev tso cai ua haujlwm kub ntawm tus neeg xyuas pib yog 70 degree, thiab qhov kev pabcuam ntev ntawm PVC yuav tsum tsis pub tshaj 65 degree. Yog li cov xov hlau thiab cables yeej nyob rau hauv lub xeev ntawm "sab hauv teeb meem thiab sab nraud aggression". Yog tias qhov zoo tsis yog raws li tus qauv, nws yuav ua rau hluav taws kub thiab lwm yam kev nyab xeeb.
Ua kom cov txheej txheem nteg, ntau thiab ntau ib puag ncig yuav tsum tau ntawm high-voltage cable khoom yuav tsum yog me me txoj kab uas hla, nyob rau hauv cov txheej txheem nteg yuav tsum tau txiav txim siab tawm hauv qhov sib txawv, nyob rau hauv thiaj li yuav dissipate lub tshav kub generated tom qab lub thaiv thiab cable energized. Cov kab ntau dhau yuav ua rau qhov nyuaj ntawm kev tso. Ib qho tshwj xeeb ntawm cov khoom zoo yog cuam tshuam los ntawm cov tsos zoo ntawm cov khoom. Txawm hais tias lub hwj chim cable lossis cov ntaub ntawv yooj yim, hauv kev tsim khoom yuav tsum tau them sai sai rau qhov zoo ntawm cov rwb thaiv tsev txheej, thiab nws cov kev tswj nruj thiab kev soj ntsuam.
Tej zaum peb yuav muaj kev tsis ntseeg, lub teeb pom kev zoo cable, qhov hluav taws xob qis hluav taws xob saum npoo yog them nrog ib txheej ntawm cov yas lossis roj hmab rwb thaiv tsev ntawm daim tawv nqaij. Txawm li cas los xij, cov kab hluav taws xob siab hauv lub tshav pob tsis tau them nrog cov tawv nqaij rwb thaiv tsev. (Lub high-voltage cables nkag mus rau hauv zej zog yog nruab nrog ib txheej rwb thaiv tsev sab nraud, uas tsuas yog ua lub luag haujlwm pabcuam thiab tsis muaj kev nyab xeeb. Nws yog ib qho tsim nyog yuav tsum xyuas kom muaj kev nyab xeeb nyob deb.) Qhov saum npoo yog du thiab ci hauv lub hnub ci. Vim li cas ntau pua volts ntawm cov hlau qhwv cov tawv nqaij, thiab kaum tawm txhiab volts, ntau pua txhiab volts ntawm high voltage hlau tab sis tsis qhwv rwb thaiv tsev daim tawv nqaij?
Qhov no yog vim tias thaum muaj hluav taws xob ntau dhau lawm, qee cov ntaub ntawv insulating, xws li roj hmab, yas, ntoo qhuav, thiab lwm yam, yuav dhau los ua cov khoom siv hluav taws xob thiab yuav tsis ua kom insulating. Wrapping rwb thaiv tsev daim tawv nqaij ntawm high voltage cable yog pov tseg ntawm cov nyiaj thiab khoom siv. Qhov saum npoo ntawm high-voltage xaim tsis npog lub rwb thaiv tsev ntawm daim tawv nqaij, thiab nws yuav xau vim kev sib cuag nrog tus pej thuam. Txhawm rau tiv thaiv qhov no, cov xaim hluav taws xob hluav taws xob ib txwm tau dai nyob rau hauv cov kab ntev ntev ntawm cov porcelain vases kom insulate lawv ntawm tus pej thuam. Tsis tas li ntawd, thaum txhim kho high-voltage cables, tsis txhob rub rau hauv av. Tsis tas li ntawd, vim qhov kev sib txhuam ntawm cov hlau thiab hauv av, cov txheej txheem rwb thaiv tsev qub qub raug puas ntsoog, muaj ntau cov burrs, cov burrs no yuav tsim tawm tawm, uas ua rau to.
Nws tuaj yeem pom tias txheej txheej rwb thaiv tsev ntawm lub cable yog teem raws li qhov xav tau ntawm cov cable. Nyob rau hauv cov txheej txheem tsim khoom, peb yuav tsum ua tib zoo ua haujlwm ntawm cov khoom siv thiab nruj me ntsis tswj cov rwb thaiv tsev tuab raws li cov qauv kev cai, uas tsis tsuas yog txuag cov peev txheej rau kev lag luam, txo cov khoom siv thiab nce cov txiaj ntsig, tab sis kuj ua kom cov kab zoo thiab tsim cov khoom lag luam siab. khoom zoo thiab pheej yig. Tau kawg, nyob rau hauv tus txheej txheem ntawm kev siv, peb yuav tsum tau them sai sai rau seb puas muaj kev puas tsuaj rau lub rwb thaiv tsev txheej thiab hloov nws nyob rau hauv lub sij hawm yog tias pom.
