摘要

高压电缆附件的膨胀效应和劣化很容易导致绝缘击穿，严重威胁高压电缆的安全稳定运行。本文提出了一种表面疏水疏油涂层的制备方法，以提高电缆附件的抗膨胀性。对硅橡胶（SiR）进行了湿热老化实验，分析了其界面性能、膨胀性能和电性能。结果表明，改性后的SiR表面形成了含碳氟键的SiO2纳米颗粒涂层，增强了样品表面对水分和硅脂的阻隔作用，抑制了SiR的膨胀和损伤效应，抑制了老化对SiR表面结构的损伤，提高了SiR的表面电导率、闪络电压和潜在衰减率。

Effect of Hydro-Oleophobicity Coating on Swelling and Insulation Properties of SiR for Cable Accessories

The swelling effect and deterioration of high-voltage cable accessories can easily lead to insulation breakdown and seriously threaten the safe and stable operation of high-voltage cables. This article proposes the preparation of a surface hydro-oleophobicity coating to enhance the swelling resistance of the cable accessories. Wet thermal aging experiments were conducted on silicone rubber (SiR), with subsequent analysis of the interface properties, swelling properties, and electrical properties. The results showed that the SiO2 nanoparticle coating containing carbon-fluorine bonds was formed on the surface of the modified SiR, which enhanced the barrier effect of the sample surface on moisture and silicone grease and suppressed the swelling and damage effect on the SiR. The modification restrained the damage of aging to the surface structure of SiR and improved the surface conductivity, flashover voltage, and potential decay rate.
