摘要

转轮法是IEC 62217—2005标准中推荐的一种重要的复合绝缘子老化试验方法

但转轮法试验中运行复合绝缘子相关性能的变化规律尚待深入研究。基于此

文中通过对4支不同运行年限的线路棒形悬式复合绝缘子进行转轮法试验

监测试验过程中绝缘子表面放电和泄漏电流的变化规律

并定期取样进行了憎水性和傅里叶变换红外光谱（FTIR）测试分析。结果表明:绝缘子表面放电程度和泄漏电流幅值呈3个阶段式发展;各阶段绝缘子憎水性能劣化速度和Si-O-Si和Si-CH3集团峰面积减少速度存在差异;憎水性劣化速度和Si-O-Si和Si-CH3集团峰面积减少速度与绝缘子老化程度呈正比。试验结果为转轮法在复合绝缘子老化评估中的应用提供了参考。

Abstract

As an important aging method of composite insulator

the tracking wheel test is recommended by IEC62217—2005 document. But it is needed to be further studied that the performances change of on-line composite in-sulators during the tracking wheel test. In the paper

the tracking wheel test is carried out on four line long rod sus-pension composite insulators which of different operating life

during which the change of surface discharge and leak-age current is monitored

the hydrophobic test and the Fourier transform infrared spectroscopy analysis（FTIR）aretested and analysis. The results descript that there are three development stages of the surface discharge and the leak-age current amplitude

during which the speed of the hydrophobic performance degradation and the Si-O-Si and Si-CH3 group peak area reduce has a difference. There also have a proportional relationship between the speed and theaging degree of composite insulator. The reference of which the tracking wheel test can be applied to evaluate the ag-ing of composite insulator is provided by the experiment result.
