摘要(Abstract)：

传统HTV硅橡胶复合绝缘子以其优异的憎水性和憎水迁移性,广泛应用于国内外输电线路上,但由于其自身力学性能欠佳,极易受强风及鸟啄损伤,严重影响着材料本身的绝缘性能。针对这一情况,采用实验室自制的改性脂环族环氧树脂高聚物复合绝缘子与传统HTV硅橡胶绝缘子在直流电晕老化性能方面进行对比,研究了环氧树脂复合绝缘子在高电压状态的老化特性。试验结果表明:直流电晕老化后环氧树脂的憎水恢复速度较慢于硅橡胶,但完全满足憎水性运行要求;而通过直流击穿场强测试发现,环氧树脂与HTV硅橡胶相比具有更好的直流击穿特性;邵氏硬度测试和拉伸性能测试表明环氧树脂材料的拉伸强度和硬度均远高于硅橡胶,具有更好的力学性能,已达到防鸟啄和耐踩踏的目的。因此,文中设计的改性环氧树脂材料可为特高压直流输电工程地区绝缘子的使用提供了一个新的发展方向。
