Effects of Operating Condition on FTIR of Composite Insulator
摘要
Abstract
To investigate aging state of composite insulators under different operating conditions,Fourier transform infrared spectroscopy is employed to analyze the composite insulators with different service time and working in different environment and voltage grade.And the change of the typical functional groups of composite insulator's umbrella skirt is also analyzed.The results show that in heavy pollution area the pollution degree of insulator surface is relatively high,leading to lower contents of Si-O-Si and Si-CH3 chains on umbrella skirt surface of the composite insulator and higher aging degree.Furthermore,mathematical statistics is adopted to obtain the absorption peak areas of Si-CH3 and Si-O-Si chains on the insulators corresponding to different voltage grade.It is shown that the absorption peak areas for the composite insulators working at different voltage grade are dispersive,and the absorption peak areas for the 220 kV insulator is obviously smaller than that for the 110 kV insulator.In general,the absorption peak areas get smaller with increasing service time of the composite insulator.关键词
