Txoj kev txhim kho thiab kev siv ntawm cov cov ntxig ntxig rau cov keeb kwm muaj keeb kwm ntau dua 40 xyoo.Qhov kev tshawb fawb thiab kev txhim kho ntawm cov kws tshuaj tiv thaiv hauv Suav teb pib thaum xyoo 1980. Lub luag haujlwm nws pib lig, nws muaj qhov pib siab. Rau lub hauv paus ntawm kev kawm paub txawv teb chaws, qhov kub thiab txias vulcanized silicone roj hmab insulators tau tsim thiab tsim thaum pib heev.Qhov 35 ~ 110kV cov txheej txheem tiv thaiv kab hluav taws xob tau muab tso rau hauv kev sim ua haujlwm hauv ib nrab xyoo 1980.Yog pib qhov kawg ntawm xyoo 1989 rau 1990 [1], Tuam Tshoj sab hnub tuaj, sab qaum teb Tuam Tshoj, sab qaum teb Tuam Tshoj thiab lwm qhov chaw muaj thaj chaw loj muaj kuab paug flashover xwm txheej uas tau tshwm sim hauv cov txheej txheem insulator rau hauv kev ua haujlwm rau kev ua haujlwm, thiab hauv 110 thiab 220 kv kab ntawm cov pa phem flashover tshwm sim, nquag thaj chaw muaj kev lom zem ntau. kev siv cov tshuaj insulator, tom qab los ntawm lub teb chaws Yelemees, Tebchaws Asmeskas thiab cov neeg tsim khoom siv hauv tsev hauv hluav taws xob hauv 500 kv daim phiaj hluav taws xob.Thaum kawg ntawm xyoo 1994, cov naj npawb ntawm cov tshuaj insulators muaj txog 50,000.Vim li ntawd, tus naj npawb ntawm cov tshuaj insulators hauv lub network muaj ob npaug xyoo tom qab xyoo, los ntawm 100,000 rau xyoo 1995 txog 200,000 hauv xyoo 1996, ntau dua 460,000 qhov kawg ntawm 1997, 600,000 thaum kawg ntawm 1998, thiab ntau dua 840,000 thaum xaus Xyoo 1999 [2] .Yog lub Kaum Hlis 2005, kwv yees li 6 plhom rau cov tshuaj tiv thaiv (hloov ua 110kV) tau tso rau hauv kev ua haujlwm hauv Suav teb.
Nyob rau 20 xyoo dhau los, daim ntawv thov thiab kev tsim kho sai ntawm cov cov ntxig hluav taws xob tau nthuav tawm qee qhov teeb meem tsis tau daws teeb meem, xws li flashover hauv cov av noo siab (ntev ntev huab, dej lwg thiab nag), lub zog hloov kho, rhuav tshem, hlua ploj, poob, noog puas, dej khov nyem thiab ua haujlwm kev siv tshuab, thiab lwm yam. [429] .Txawm li ntawd, kev ua haujlwm tau ua haujlwm tau qhia meej tias kev siv cov roj hmab silicone sib xyaw ua ke tiv thaiv qhov chaw loj muaj kuab paug flashover sib tsoo, zoo heev txo qhov qub impurity cheeb tsam hnyav ntxuav thiab xoom nrhiav thiab yog li ntawm kev saib xyuas kev ua haujlwm thiab tswj kev ua haujlwm, dhau los ua peb lub teb chaws hauv kev daws teeb meem kis kab hluav taws xob rwb thaiv tsev sab nraud ntawm cov pa phem nyob rau hauv cov chaw muaj kuab paug ib qho ntawm cov qauv zoo tshaj plaws.Qhov kev qhia qib thiab daim ntawv thov ntawm cov ntxig hluav taws xob hauv Suav teb tau rau hauv lub ntiaj teb' s ua thawj theem, thiab lawv cov kev ua haujlwm tau ua rau muaj kev nyiam ntawm CIGRE thiab IEC.
