Abstract
In order to control the situation of operating performance change of the running composite insulator, this paper introduces development of sampling inspection on transmission line composite insulator in the last four years of Guangdong power grid, and systematic experimental inspection on its macroscopic performance including hydrophobicity inspection, mechanical failure load, sealing property test , water diffusion with sheath, and so on. Sampling inspection results indicate that mechanical property of the composite insulator and sealing property of its ends are stable but performance such as interface adhesion, hydrophobicity and electrical erosion resistance of the umbrella skirt is clearly aging. Aging of performance is related with operating years of the composite insulator, performance of interface adhesion and electrical erosion resistance of the umbrella decreases obviously after the insulator operating over 8 years. In addition, declination of interface adhesion may cause declination of mechanical property of the core rod and even cause breakage fault, which should be closely paid attention to in operation and maintenance process.关键词
