摘　　要：介绍了国际上现有的几个复合绝缘子老化试验方法的特点,并对我国现场运行复合绝缘子的老化现象进行分析,在此基础上以模拟硅橡胶复合绝缘子在现场运行中的老化模式为目的,设计、建造了相应的试验装置,进行了多种人工加速老化试验,并比较了不同方法的可行性和合理性。结果表明,各种老化方法都有自己的优势和特点,但适合国内情况的老化方法还有待于更深入的研究。The features of several existing ageing test method for composite insulators abroad are presented. The ageing phenomena of domestic composite insulators put into field operation is analyzed, on this basis for the purpose of simulating the ageing mode of composite insulators made of silicon rubber, which are put into field operation, corresponding testing equipments are designed and built with which a variety of artificial accelerated ageing tests are performed, and the feasibility and reasonableness of different test methods are compared. Comparison results show that existing ageing test methods have their own superiorities and properties, and it is to be further researched for the ageing method suitable to the icing conditions in China.
