耐漏电起痕硅橡胶的制备及应用研究进展

硅橡胶以其优异的电气绝缘性、憎水防污和耐污闪等性能而广泛应用于高压超高压电力电气设备及外绝缘领域。然而硅橡胶绝缘材料在长期使用过程中,在外界强电场放电作用下会发生漏电起痕破坏,致使材料失效甚至燃烧。这对电力系统与电气设备的安全运行,以及人们的生产和生活造成巨大的危害。因此,硅橡胶的耐漏电起痕研究吸引了越来越多研究者的关注。文中综述了近年来国内外关于耐漏电起痕硅橡胶的最新研究进展,分析了硅橡胶耐漏电起痕剂亟待解决的问题,并指出高效率、相容好、多功能的有机耐漏电起痕剂是耐电痕化硅橡胶的重要发展方向。

Progress in the Preparation and Application of Tracking and Erosion Resistant Silicone Rubber

Silicone rubber is widely used in high-voltage and super-high voltage electrical equipments and outdoor insulation,due to its excellent electrical insulation,water-repellence and flashover resistance.However,when served for a long time,silicone rubber insulation materials may suffer from tracking and erosion,resulting in insulation failure and even fire,because of strong external discharges.This caused great harm to the safety of the operation of power transmission systems and electrical equipment,as well as the industrial production and daily life of human.Therefore,research on the tracking and erosion resistance of silicone rubber attracted more and more attention.This paper reviewed the latest progress in the research of tracking and erosion resistant silicone rubber and analyzes the problems needed to be solved.Finally,it is pointed out that versatile organic agent for tracking and erosion resistance of silicone rubber with high efficiency and good compatibility is one of the most important developmental trends.
