摘要

复合绝缘子具有质量轻、憎水性好等优点

但也易老化

复合绝缘子老化评估成为急需解决的问题。该试验借助傅里叶变换红外光谱（fourier transform infrared spectroscopy

FTIR）憎水性喷水法和硬度测试

对不同电压等级和不同运行年限的复合绝缘子进行老化状态评估。初步探寻了电压等级和运行年限等因素与现场复合绝缘子的FTIR测试之间的联系。结果表明

运行电压等级越高绝缘子各位置基团吸收峰面积和老化程度越不均匀;随着运行年限的增加基团吸收峰呈现降低的趋势

结合憎水性试验和微观结构分析

表明FTIR测试在一定程度上可以对老化绝缘子进行评估

并尝试提出了绝缘子老化程度划分依据。

Abstract

To assess the aging condition of composite insulators under different voltage levels and operating years

Fourier transform infrared spectroscopy（FTIR） test

HC water spray hydrophobicity test

and hardness test were conducted. The relations of the factors

such as voltage levels and operating years

with the results of field FTIR test of composite insulators were obtained. It is shown that the higher the voltage level is

the more uneven the absorption peak area of each group and the aging condition become. With the increase of operating years

the absorption peak of each group lowers. It is concluded that combining with hydrophobic test and microstructure analysis

FTIR test can be applied to aging condition assessment of insulators to some extent. Moreover

a grading criterion of aging condition of insulator is suggested.
