Cov qauv yooj yim ntawm lub hwj chim cable yog tsim ntawm plaub ntu: Tus Core hlau (tus kws kos duab), rwb thaiv tsev txheej, ntaub thaiv npog txheej thiab tiv thaiv txheej. Lub rwb thaiv tsev txheej yog qhov hluav taws xob rho tawm ntawm cov hlau core thiab hauv av thiab sib txawv ntawm cov khoom sib txawv ntawm lub zog hluav taws xob, thiab yog qhov tseem ceeb ntawm lub hwj chim cable qauv.
Lub luag haujlwm ntawm cov rwb thaiv tsev txheej:
Lub tub ntxhais ntawm txoj hlua cab yog tus neeg xyuas. Txhawm rau tiv thaiv cov khoom siv puas tsuaj los ntawm cov xaim hluav taws xob luv luv ntawm cov xaim hluav taws xob thiab cov neeg muaj zog tshaj li ntawm cov khoom tiv thaiv kev nyab xeeb, txheej txheem tiv thaiv kev tiv thaiv yuav tsum tau ntxiv rau cable. Qhov hluav taws xob tiv thaiv cov hlau tus neeg coj ua hauv lub cable yog qhov me me, thiab hluav taws xob tiv taus cov insulator yog siab heev. Qhov laj thawj yog vim li cas insulator tuaj yeem ua tau insulated yog vim: qhov kev them nyiaj tsis zoo thiab tsis zoo yog tsis quav ntsej, thiab nws tsis zoo yog tsis quav ntsej, thiab nws tau suav hais tias yog cov tshuaj tsis yog ua haujlwm. Rau insulators, muaj qhov tawg yuam uas muab cov tshuab hluav taws xob txaus kom muaj zog kom txaus siab rau lawv. Thaum tawg qhov hluav taws xob tau dhau lawm, cov khoom siv tsis muaj kev tswj cov tshuaj ntxiv.
Dab tsi yog qhov cuam tshuam ntawm kev tsis tsim nyog rwb thaiv tsev tuab ntawm lub cable?
Luv tawm cov kev pabcuam lub neej ntawm cov xaim thiab cov khoom lag luam cable, yog tias muaj kev ua haujlwm sab nraud, tom qab kev ua haujlwm ntev ntawm cov hnab riam los txo qis. Cov kev sim ua pov cov tshuaj ntsuam pov tseg lossis kab ua haujlwm tsis ua haujlwm, cov phiaj xwm nyias yuav tawg, cov nyhuv tiv thaiv ntawm cable sheath yuav ploj. Ib qho ntxiv, kev siv hauv sab hauv yuav tsis raug quav ntsej, xaim thiab cable ntev lub zog yuav tsim kom muaj cua sov, nws yuav ua rau lub neej luv ntawm cov xaim thiab cable. Yog tias qhov zoo tsis tau txog ntawm tus qauv, nws yuav ua rau hluav taws thiab lwm yam kev nyab xeeb.
Ua kom muaj kev nyuaj ntawm cov txheej txheem pw, yog li cov qauv tuab, yog li nws tsis tuaj yeem ua lub luag haujlwm ntawm kev tiv thaiv cov xaim thiab cable. Ib qho ntawm cov yam ntxwv ntawm cov khoom zoo yog xav txog hauv cov tsos zoo ntawm cov khoom. Seb nws yog lub hwj huam cable lossis ib daim ntaub yooj yim xaim xaim, qhov zoo tshaj ntawm cov rwb thaiv tsev txheej yuav tsum tau them nyiaj rau hauv kev tsim khoom, thiab nws yuav tsum tau siv nruj me ntsis thiab kuaj.
Tej zaum muaj coob tus neeg yuav muaj kev ua xyuav, vim tias lub teeb ci cable thiab cov txheej txheem roj hmab, thiab cov roj av hluav taws xob, thiab cov roj av hluav taws xob hauv teb tsis duav nrog rwb thaiv tsev.
Vim tias muaj ntau dhau qhov hluav taws xob, qee cov ntaub ntawv uas yog keeb kwm insulating, xws li cov roj hmab, yas, yuav kuj tsis muaj cov nyhuv insulating. Wrapping rwb thaiv tsev ntawm high-voltage cables yog khib nyiab ntawm cov nyiaj thiab cov peev txheej. Qhov saum npoo ntawm cov hlau hluav taws xob high-voltage tsis duav nrog rwb thaiv tsev nrog rwb thaiv tsev, thiab yog tias nws raug tshem tawm ntawm tus pej thuam siab, nws tuaj yeem txi hluav taws xob vim muaj ntauwd. Txhawm rau tiv thaiv qhov tshwm sim no, cov hlau siab xaim hluav taws xob ib txwm raug ncua nyob rau hauv ntev ntawm cov raj hluav taws xob ntev, yog li ntawd lub siab loj hlau yog insulated los ntawm tus pej thuam. Ib qho ntxiv, thaum txhim kho qib high-voltage, tsis txhob rub lawv rau hauv av. Txwv tsis pub, vim kev sib txhuam ntawm cov xaim thiab av, renialy rwb thaiv tsev txheej yog puas, thiab muaj ntau yam burrs, uas yuav tsim tawm, ua kom muaj kev tawm paug, ua kom muaj kev tawm paug, ua rau muaj kev xau.
Lub rwb thaiv tsev txheej ntawm lub cable yog teem raws li qhov xav tau ntawm lub cable. Hauv cov txheej txheem ntau lawm, cov chaw tsim khoom yuav tsum tau tswj cov rwb thaiv rwb thaiv cov txheej txheem ua raws cov txheej txheem kev tswj hwm, thiab ua kom zoo nkauj txheej txheem xaim thiab cable.
