為探究表面狀態(tài)對(duì)硅橡膠電暈老化進(jìn)程及特性的影響,采用多針-板電極對(duì)表面清潔和表面覆污的硅橡膠樣品進(jìn)行不同時(shí)長(zhǎng)的電暈老化試驗(yàn),測(cè)量老化前后材料表面憎水性和微觀結(jié)構(gòu)的變化,并在人工霧室中完成沿面閃絡(luò)試驗(yàn)。研究結(jié)果表明:相較于表面清潔的硅橡膠,在一定程度上,表面污穢會(huì)減弱電暈放電對(duì)硅橡膠材料的影響,隨著污穢度的增加,老化前后靜態(tài)接觸角變化逐漸減小,電暈放電對(duì)硅橡膠表面的破壞性減弱;硅橡膠的閃絡(luò)電壓隨表面污穢度的增大而降低,并逐漸趨于平穩(wěn),同時(shí)老化程度越深,閃絡(luò)電壓也越低。本文的研究結(jié)果可為硅橡膠復(fù)合絕緣子設(shè)計(jì)和防污閃提供參考。
- Abstract:

In order to explore the effects of surface condition on the corona aging process and characteristics of silicone rubber, this paper uses a multi-needle-plate electrode to conduct corona aging tests for different time on silicone rubber samples with clean and soiled surfaces, measures changes in the hydrophobicity and microstructure of the material surface before and after aging, and tests the surface flashover voltage in the artificial fog chamber. The research results show that: compared with silicone rubber with clean surface, to a certain extent, surface contamination will weaken the impact of corona discharge on silicone rubber surface, with the increase of pollution degree, the change of static contact angle after aging gradually decreases, and the destructive effect from corona discharge on the surface of silicone rubber weakens; the flashover voltage of silicone rubber decreases with the increase of pollution degree and gradually stabilizes, at the same time, the deeper the aging degree, the lower the flashover voltage. The results of this paper may provide a reference for the design and anti-pollution flashover of silicone rubber composite insulators.
