Cov ncauj lus yooj yim ntawm cov plooj (porcelain composite insulator) siv los txhawb thiab ntxig rau cov hlau yog hu ua plooj (porcelain composite insulator) Cov plooj (veneers) puas muaj qhov ua los ntawm cov seem, cov kaus mom hlau, steel taw, thiab cov roj hmab sib xyaw. Vim tias qhov zoo los tiv thaiv kev ua qias tuaj muaj peev xwm ntawm cov plooj (porcelain composite insulators), cov naj npawb ntawm cov khoom siv tuaj yeem txo kom txo qhov ntev ntawm txoj hlua, tuaj yeem txo qhov siab ntawm cov hlau ntau thiab nws tus kheej lub teeb nyhav. Kev siv loj-tonnage cov plooj (iav) cov cov kab hluav taws xob tiv thaiv yog qhov tseem ceeb tshaj rau kev tsim kho UHV cov haujlwm.
1. Kev daws qhov teeb meem flashover teeb meem ntawm cov plooj (porcelain) thiab cov iav ua haujlwm tsis zoo
Nrog txoj kev loj hlob sai ntawm kev tsim kho kev lag luam, atmospheric thiab kev lag luam ib puag ncig muaj kuab paug tseem ntau zuj zus. Hauv qhov huab cua ntub ntawm nag, huab, te, lwg, thiab lwm yam hauv qhov, cov tshuaj lom rau hauv av hauv cov nplaim dej thiab cov iav insulators yuav maj mam yaj hauv dej, thiab dej zaj duab xis nrog qee yam kev coj ua yuav tsim nyob rau nplaim ntawm cov rwb thaiv tsev. Yog hais tias lub insulator yog qhov qias neeg thiab lub nplaim ntawm cov insulator yog qhov txaus lawm, lub zog muaj paug tawm qhov yuav tshwm sim, uas yuav yooj yim ua rau muaj kuab paug flashover.
2. Daws daws" nkig tawg" teeb meem ntawm cov khoom siv zoo li tus pas nrig hluav taws xob txhaws kab
Raws li cov ntaub ntawv tsim nyog: Hauv kev kho tshuab kev puas tsuaj ntawm cov organic insulators," brittle tawg" ntawm qhov tseem ceeb qws suav tau 60% ntawm tus pas nrig loj tawg qhov teeb meem uas tau tshwm sim, thiab 35% ntawm tag nrho cov kev sib tsoo tshuab." nkig tawg" ntawm lub mandrel tau dhau los ua kev phom sij tshaj plaws nyob rau hauv tam sim no cov organic sib xyaw insulator.
3. Ua rau cov teeb meem uas cov ntxig hluav taws xob tsis tuaj yeem siv rau txoj hlua tensile
Tam sim no, kuv lub teb chaws' s sib xyaw ua kom tsis muaj zog tsis siv dav hauv kev siv cov hlua, feem ntau yog vim muaj kev txhawj xeeb txog cov tshuab tsis muaj zog ntawm cov ntxig hluav taws xob. Tom qab tag nrho, kuv lub teb chaws' s cov hluavtaws hluavtaws muaj cov kev paub ua haujlwm tsawg dua li txawv tebchaws. Tshwj xeeb tshaj yog tom qab cov organic puas insulator tawg rau ntawm cov kab hluav taws xob loj, qee qhov ua kom cov kab hluav taws xob siv rau ntawm cov kab uas tsis muaj zog insulator yog hloov nrog cov plooj (plooj) lossis cov iav insulators kom ntseeg tau ruaj khov thiab txhim khu kev ntseeg lub zog.
