1. Tsawg ua haujlwm ua haujlwm tsawg
Flashover thiab kev puas tsuaj ntawm cov kab hluav taws xob ua ke tau tshwm sim ntau zaus txij li xyoo 1998, thiab lawv cov teeb meem tuaj yeem muab faib ua txoj hlua sib tsoo thiab flashover kev sib tsoo.Qhov qub yog cov khoom lag luam teeb meem zoo; Lub tom kawg muaj feem xyuam rau kev siv tsis raug vim tsis muaj kev ua haujlwm, thiab kuj tseem cuam tshuam txog kev tsis zoo ntawm cov roj hmab silicone.Thaum ob xyoos dhau los, nrog kev txhim kho txuas ntxiv ntawm cov duab ntawm cov ntxig hluav taws xob lub kaus mom tiab luv, kev siv lub tshuab khi kawg, lub kaus tes sib sau tshuab, kev ntseeg tau ntawm kev siv lub zog thiab kev tswj kom zoo, kev ua haujlwm raug mob ntawm insulator puas txo qis, thiab kev tsim thev naus laus zis tau mus txog thoob ntiaj teb kev theem pib.
2. Cov uas muaj ntau yam ntawm daim ntawv thov los ua ntau thiab dav dua
Comulite insulators tsis yog tsuas yog siv hauv Suav teb xwb, tab sis kuj tau xa tawm hauv ntau qhov ntau ntxiv.Thaum kawg lub Kaum Hlis 2005, muaj txog 30,000 cov hluav taws xob hauv cov hluav taws xob tau siv rau hauv Suav teb' s DC fais fab kis kab, suav tau ntau dua li ib nrab ntawm dc insulators.Not tsuas yog siv rau sab nrauv kis kab, tab sis kuj maj mam siv rau hauv cov chaw hloov pauv.Thaum tam sim no, qee qhov ntawm 110 thiab 220kV kab hluav taws xob hauv tebchaws tau pib siv cov kab hluav taws xob hauv cov kab hluav taws xob thiab kab tsheb npav, thiab kom deb li deb lawv tau zoo lag luam tsis tau tsuas yog rau txoj hlua dai, tab sis tseem nce ntxiv rau cov nyom thiab cov hlua khi.Qhov insulators tau siv dav hauv txhua qhov ntawm lub zog, thiab lawv cov kev ua tau zoo thiab kev ntseeg siab tau tau txais dav thiab hais tawm.
