Thaum lub sijhawm ua haujlwm ntev ntawm cov insulators, lawv raug cuam tshuam rau ntau yam ntuj thiab dag zog. Cov pa phem tso rau saum npoo ntawm cov insulators yuav txo tau cov hluav taws xob lub zog ntawm cov insulators nyob rau hauv qhov kev txiav txim ntawm huab cua tej yam kev mob xws li los nag, daus, pos huab thiab Frost, raws li zoo raws li ib tug tshwj xeeb ib puag ncig, xws li lub sij hawm ntev emission ntawm chemical gas. tshuaj nroj tsuag nyob ib ncig ntawm kab, thiab yog li muaj kuab paug flashover xwm txheej yuav tshwm sim. Yog li, dab tsi yog qhov tshwj xeeb muaj kuab paug ntawm insulators?
(1) Cov pa phem: feem ntau yog tsim nyob rau hauv tej yam kev mob ntawm cov pa phem, tshwj xeeb tshaj yog yuav muab faib ua plua plav paug, ntsev thiab alkali muaj kuab paug, hiav txwv ntsev los yog seawater muaj kuab paug, guano pollution;
(2) Ice thiab daus muaj kuab paug: Cov dej khov thiab cov daus muaj kuab paug yog cov pa phem tshwj xeeb ntawm cov rwb thaiv tsev. Thaum cov dej khov los yog daus yaj, nws yuav ua rau muaj kev txhim kho zoo ntawm cov hluav taws xob hluav taws xob, uas ua rau cov hluav taws xob hluav taws xob tsis sib haum nyob rau hauv qhov kev khiav hauj lwm voltage, uas tseem hu ua dej khov flashover kev huam yuaj.
(3) Industrial pollution: industrial pollution yog hais txog cov roj theem, cov kua theem, thiab cov theem cov pa phem tawm hauv cov txheej txheem ntawm kev tsim khoom, uas feem ntau tshwm sim nyob rau hauv cov nroog, suburbs thiab industrial concentrated cheeb tsam, nrog rau cov hais saum toj no tshuaj nroj tsuag, smelters. thiab thermal fais fab nroj tsuag pa luam yeeb, cement nroj tsuag, thee thiab mine plua plav, circulating dej txias ntauwd los yog ciav acidizing dej pos huab.
