Kev ua haujlwm thiab kev xav tau ntawm cov insulators

Lub luag haujlwm tseem ceeb ntawm cov insulators yog kom ua tiav cov hluav taws xob rwb thaiv tsev thiab cov khoom siv kho kom zoo, uas tau teev tseg ntau yam kev ua haujlwm ntawm hluav taws xob thiab kev ua haujlwm. Yog hais tias tsis muaj kev puas tsuaj los yog flashover raws qhov chaw nyob rau hauv qhov kev txiav txim ntawm qhov kev khiav hauj lwm voltage, xob laim overvoltage thiab sab hauv overvoltage; nyob rau hauv qhov kev txiav txim ntawm lub sij hawm ntev thiab luv-term mechanical loads, tsis muaj kev puas tsuaj los yog kev puas tsuaj yuav tshwm sim; nyob rau hauv lub tshuab uas tau teev tseg, hluav taws xob thauj khoom thiab kev ua haujlwm mus sij hawm ntev nyob rau hauv ntau yam kev mob ib puag ncig, yuav tsis muaj kev cuam tshuam pom tseeb; cov khoom siv ntawm lub insulator yuav tsis tsim kom pom tseeb corona tawm tshwm sim nyob rau hauv kev khiav hauj lwm voltage, thiaj li tsis mus cuam tshuam nrog lub txais xov tooj cua los yog TV. Vim tias cov insulators yog cov khoom siv dav siv, lawv cov khoom siv sib txuas kuj yuav tsum muaj kev sib hloov. Tsis tas li ntawd, cov qauv txheej txheem ntawm cov insulators kuj xav tau ntau yam hluav taws xob, tshuab, lub cev thiab ib puag ncig kev hloov pauv ntawm cov insulators los xyuas lawv cov kev ua tau zoo thiab zoo raws li cov qauv sib txawv thiab kev siv.
