Tam sim no, peb hom khoom siv feem ntau siv los ua cov kab hluav taws xob hauv kab hluav taws xob kis kab hluav taws xob, uas yog cov plooj (plooj), iav thiab cov kab hluav taws xob. yog qhov yuav tsum tau ua, thiab kev ua haujlwm thiab kev saib xyuas haujlwm yuav tsum raug txo kom ntau li ntau tau.Flashover, poob kab, tawg, tawg ntawm lub zog thiab lwm yam xwm txheej hauv kev ua haujlwm ntawm cov nyiaj siv ua haujlwm sab saum toj yuav ua rau lub zog tsis ua haujlwm hauv thaj chaw loj thiab coj loj poob rau kev lag luam hauv teb chaws.Yog li ntawd, kev xaiv cov kab hluav taws xob yog qhov tseem ceeb heev hauv kev tsim cov kab txuas kev xa.
Cov khoom qauv ntawm cov rwb thaiv tsev ：
1. Cov plooj (veneers) insulator
Porcelain yog ib hom khoom siv ntawm polycrystalline, uas yog ua los ntawm av nplaum thiab sintered ntawm qhov kub. Nws microstructure yog li ntawm polycrystals thiab microporous iav ua theem. Nws yog ib hom ntawm heterogeneous polycrystalline khoom.Porcelain cov tuam txhab tswj cov khoom siv raw, tshuaj tawg, ntsuas kub, thiab cov txheej txheem tua kom ua tiav qhov zoo tshaj plaws ntawm kev sib cuam tshuam sab hauv nruab nrab ntawm cov kua siv lead ua, cov micropores, thiab cov iav theem.Hauv cov neeg tsim khoom (NGK) siv cov hmoov ultrafine zoo. alumina kev lag luam hauv cov ntaub ntawv nyoos, thiab siv cov khoom siv zoo, uas tuaj yeem txhim kho cov tshuab muaj zog thiab hluav taws xob muaj zog ntawm cov hniav zoo nkauj.
2. Cov iav rwb thaiv tsev
Cov iav, cov khoom zoo ib yam li cov plooj (porcelain) tau siv.Glass los ntawm quartz xuab zeb, dolomite, feldspar, limestone thiab tshuaj nyoos cov khoom siv (xws li poov tshuaj carbonate, sodium) los ntawm qhov kub siab yaj mus ua kua, tab sis lub sijhawm no cov khoom siv hlau tag yog homogeneous kiag li, ntom qauv ntawm cov khoom siv, yog li tsis muaj kev loj hlob ntawm kev sib tham sab hauv ntawm cov kab mob me me.Thaum cov txheej txheem tempering, kom ntau dua, qhov siab compressive yog tsim rau sab nrauv ntawm lub khob insulator, yog li ntawd lub zog ntawm saum npoo tsis xws luag yog tshem tawm, thiab cov neeg kho tshuab lub zog muaj kev txhim kho zoo heev, kom lub zog tensile ntawm cov khoom tuaj yeem ua kom tsis muaj dab tsi hauv tag nrho cov txheej txheem ua haujlwm.
3. Cov rwb thaiv tsev
Cov ntxig hluav taws xob kuj yog hu ua cov organic sib xyaw ua cov insulators thiab silicone roj hmab insulators, tab sis cov ntaub ntawv thiab cov qauv ntawm ob lub hluavtaws hluavtaws yog qhov zoo sib xws. kev ua tau zoo. Nws tseem yog sab hluav taws xob sab hauv ntawm cov hluavtaws. Nws muaj lub zog loj tensile, zoo creep tsis kam, zoo vibration damping thiab muaj zog qaug zog lub cev tsis kam. Tam sim no qee cov tuam ntxhab siv ECR hloov acid tiv taus mandrel, zoo heev txhim kho qib ntawm acid tiv thaiv thiab hluav taws xob corrosion tsis kam ntawm mandrel.Ua kaus disc, kuj hu ua tiab , yog sab nraud rwb thaiv tsev ntawm cov ntxig hluav taws xob, feem ntau muab creepage nrug los tiv thaiv mandril los ntawm cov huab cua puag.Umbrella tais yog feem ntau ua los ntawm cov siab molecular polymer nrog silicone roj hmab ua cov lej, ntxiv ntau hom sau los ntawm cov qauv tshwj xeeb thiab cov txheej txheem.Qhov kev txuas ntawm cov roj hmab silicone tiab, manrod thiab kawg fittings yog lub tshuab tseem ceeb. Nyob rau tam sim no, cov cuab yeej ib txwm xws li gluing thiab extrusion sib raug zoo tau hloov mus rau lub thev naus laus zis tshiab ntawm kev txuas ntxiv ntawm lub tsho ntxiv, lub siab kub thiab siab siab silicone roj hmab txhaj tshuaj foob thiab arc tig chaw, uas tuaj yeem tswj tau qhov kev sib khi thiab kev txhim kho ntawm peb Cov.
