1. Sib piv ntawm lub neej pabcuam
GG quot; Kev pab cuam lub neej" txhais tau hais tias lub neej muab kev pab cuam ntawm cov neeg kho tshuab thiab hluav taws xob lub zog ntawm cov khoom tsis pub tsawg tshaj li lub Hoobkas nqi raws li cov xwm txheej tau teev tseg nyob hauv tus qauv.Qhov txawv" kev pab cuam lub neej" ntawm peb hom insulators yog txiav txim siab los ntawm lawv cov sib txawv ntawm cov qauv thiab cov txheej txheem tsim tawm.Tom qab 15 ~ 25 xyoo ntawm kev ua haujlwm, tus nqi kuaj ntawm cov khoom siv hauv tsev plooj (veneers) insulator tsis ncav cuag lub Hoobkas txheej txheem. Tus nqi tsis tsim nyog ntawm txhua qhov kev xeem nce xyoo ntawm xyoo, thiab cov laus ua ntau dua thiab ntau dua.Hauv li cas, qhov zoo ntawm cov plooj (veneers) insulator ua los ntawm NGK Tangshan Electric porcelain Co., Ltd. tau mus txog thoob ntiaj teb qib theem ntawm tib hom, nrog rau cov kev pabcuam lub sijhawm uas yuav tsum muaj ntau dua 30 txog 50 xyoo, thiab qhov kev xeb zuj zus tau mus txog theem qib tsis ntau dua 1 / 100,000 ib xyoo.
2. Cov khoom siv roj hmab silicone ntawm cov hluavtaws insulator muaj hydrophobicity zoo, thiab cov hydrophobicity tseem tuaj yeem hloov tau.Hauv cov tsiv teb tsaws, qhov chaw ntawm cov kuab paug txheej kuj muaj hydrophobicity, thiab nws cov dej hauv av tshwm tuaj rau hauv cov kua dej me me, hauv qab qhov kev ua haujlwm ntawm tas mus li voltage, nws yog qhov nyuaj rau tsim cov kwj paug tawm, yog li nws tuaj yeem tswj lub teeb tsa hluav taws xob tsis zoo rau lub sijhawm ntev.Thaum ntxiv, cov qauv thiab cov duab ntawm cov hluavtaws hluavtaws tsis zoo rau qhov nqus thiab txuam ntawm cov pa phem, thiab lawv muaj qhov zoo kev tu tus kheej kev ua tau zoo hauv ib puag ncig ntuj.Qhov nplaim hydrophobicity ntawm plooj hlau plooj (insulator) thiab cov iav insulator yog qhov tsis zoo, thiab nws yooj yim los tsim cov arc rau saum npoo thiab ua rau muaj kuab paug flashover nyob rau hauv qhov kev ua ntawm voltage tom qab fouling txuam nrog. Lub caij no, ntau txheej txheem plooj (plooj tsev) thiab cov iav insulator yog nruab nrog lub tswb thiab lub qhov sib sib zog nqus hom, uas ua rau nws nyuaj rau tus kheej ua kom huv thiab huv ntawm cov rwb thaiv tsev thiab tsis ncaj rau txo kev ua qias tuaj.
