Vim li cas Cov Txheej Txheem Cable Insulation thiaj li tseem ceeb rau kev ua tau zoo？

Cov qauv yooj yim ntawm cov xov hluav taws xob muaj plaub ntu: lub plawv hlau (tus neeg coj hluav taws xob), txheej rwb thaiv tsev, txheej tiv thaiv thiab txheej tiv thaiv. Cov txheej rwb thaiv tsev yog qhov hluav taws xob cais ntawm lub plawv hlau thiab av thiab cov theem sib txawv ntawm lub plawv hlau kom ntseeg tau tias muaj kev xa hluav taws xob, thiab yog ib feem tseem ceeb ntawm cov qauv cable fais fab.

Lub luag haujlwm ntawm cov txheej txheem rwb thaiv tsev:

Lub plawv ntawm ib lub cable yog ib tug conductor. Yuav kom tiv thaiv cov khoom siv puas tsuaj los ntawm luv luv circuit ntawm cov xov hlau raug thiab kev puas tsuaj rau tib neeg los ntawm cov xov hlau uas tshaj qhov kev nyab xeeb voltage, ib txheej insulating tiv thaiv yuav tsum tau ntxiv rau lub cable. Lub resistivity hluav taws xob ntawm cov hlau conductor hauv lub cable yog me me heev, thiab lub resistivity hluav taws xob ntawm lub insulator yog siab heev. Qhov laj thawj vim li cas lub insulator tuaj yeem insulated yog vim: cov nqi zoo thiab tsis zoo hauv cov molecules ntawm lub insulator yog khi nruj heev, cov khoom them uas tuaj yeem txav mus los ywj pheej yog tsawg heev, thiab lub resistivity yog loj heev, yog li feem ntau, macro tam sim no tsim los ntawm kev txav mus los dawb them nyob rau hauv qhov kev ua ntawm lub teb hluav taws xob sab nraud tuaj yeem tsis quav ntsej, thiab nws suav hais tias yog ib yam khoom tsis-conductive. Rau cov insulators, muaj lub zog tawg uas muab cov electrons txaus lub zog los txhawb lawv. Thaum lub zog tawg dhau lawm, cov khoom siv tsis insulated lawm.

Qhov cuam tshuam ntawm qhov tuab ntawm cov rwb thaiv tsev tsis tsim nyog rau ntawm lub cable yog dab tsi?

Ua kom lub neej ua haujlwm ntawm cov hlau thiab cov khoom siv cable luv dua, yog tias qhov nyias nyias ntawm lub plhaub cable tsis ua raws li qhov yuav tsum tau ua, tom qab ua haujlwm ntev, tshwj xeeb tshaj yog nyob rau hauv qhov chaw faus ncaj qha, hauv qab dej, qhib lossis corrosive ib puag ncig, vim yog qhov xeb ntev ntawm cov khoom siv sab nraud, qib rwb thaiv tsev thiab qib kho tshuab ntawm qhov nyias nyias ntawm lub plhaub yuav raug txo qis. Kev kuaj xyuas lub plhaub tsis tu ncua lossis kev ua tsis tiav ntawm kab av, qhov nyias nyias yuav raug rhuav tshem, qhov cuam tshuam tiv thaiv ntawm lub plhaub cable yuav ploj mus. Tsis tas li ntawd, kev siv sab hauv tsis tuaj yeem tsis quav ntsej, lub zog hluav taws xob ntev ntawm hlau thiab cable yuav tsim ntau cua sov, nws yuav ua rau lub neej ua haujlwm ntawm hlau thiab cable luv dua. Yog tias qhov zoo tsis raws li tus qauv, nws yuav ua rau hluav taws thiab lwm yam kev phom sij rau kev nyab xeeb.

Ua kom qhov nyuaj ntawm cov txheej txheem tso, thaum lub sijhawm tso yuav tsum xav txog qhov tawm ntawm qhov sib txawv, kom cov cua sov tsim tawm tom qab lub zog ntawm cov hlau thiab cable, qhov tuab ntawm lub plhaub tuab dhau yuav ua rau qhov nyuaj ntawm kev tso, yog li qhov tuab ntawm lub plhaub yuav tsum ua raws li cov qauv tsim nyog, txwv tsis pub nws tsis tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv cov hlau thiab cable. Ib qho ntawm cov yam ntxwv ntawm cov khoom zoo yog pom hauv qhov zoo ntawm cov khoom. Txawm hais tias nws yog lub zog cable lossis cov ntaub yooj yim, qhov zoo ntawm cov txheej rwb thaiv tsev yuav tsum tau them sai sai rau hauv kev tsim khoom, thiab nws yuav tsum tau tswj hwm thiab sim nruj me ntsis.

Tej zaum ntau tus neeg yuav muaj kev tsis ntseeg, vim tias lub luag haujlwm ntawm cov txheej rwb thaiv tsev loj heev, qhov chaw ntawm cov teeb pom kev zoo cable thiab cov cable qis-voltage yog them nrog ib txheej ntawm cov yas lossis roj hmab rwb thaiv tsev, thiab cov cable siab-voltage hauv thaj teb tsis tau them nrog rwb thaiv tsev.

Vim tias thaum muaj hluav taws xob ntau dhau, qee cov ntaub ntawv uas yog cov rwb thaiv tsev, xws li roj hmab, yas, ntoo qhuav, thiab lwm yam, kuj yuav dhau los ua cov neeg coj hluav taws xob, thiab yuav tsis muaj cov nyhuv rwb thaiv tsev. Kev qhwv rwb thaiv tsev rau ntawm cov xov hluav taws xob siab yog kev nkim nyiaj thiab cov peev txheej. Qhov chaw ntawm cov xov hluav taws xob siab tsis tau npog nrog rwb thaiv tsev, thiab yog tias nws raug dai rau ntawm lub pej thuam siab, nws yuav xau hluav taws xob vim yog kev sib cuag nrog lub pej thuam. Txhawm rau tiv thaiv qhov xwm txheej no, cov xov hluav taws xob siab ib txwm raug dai rau hauv qab cov fwj porcelain uas muaj rwb thaiv tsev zoo, yog li cov xov hluav taws xob siab raug rwb thaiv tsev los ntawm lub pej thuam. Tsis tas li ntawd, thaum txhim kho cov xov hluav taws xob siab, tsis txhob rub lawv rau hauv av. Txwv tsis pub, vim muaj kev sib txhuam ntawm cov xov hlau thiab hauv av, cov txheej rwb thaiv tsev du qub raug puas tsuaj, thiab muaj ntau lub burrs, uas yuav tsim cov taub tawm, ua rau muaj kev xau.

Cov txheej rwb thaiv tsev ntawm cov xov hlau raug teeb tsa raws li qhov xav tau ntawm cov xov hlau. Hauv cov txheej txheem tsim khoom, cov chaw tsim khoom yuav tsum tswj cov tuab ntawm cov rwb thaiv tsev kom nruj raws li cov qauv txheej txheem, ua tiav kev tswj hwm cov txheej txheem, thiab xyuas kom meej qhov zoo ntawm cov xov hlau thiab cov xov hlau.
