摘要
Abstract
In order to study the interface problems of running composite insulator, 37, 68 and 38 composite insulators with different operating years are selected respectively from Guangdong, Guangxi and Hebei areas to test the performance of the interfaces between the core and sheds, between fittings, cores and sheds material, and between the housing and sheds. It is discovered by using the statistical analysis method that 50% of the early composite insulators have poor bondings between the housing and the core; the end fittings and sealants become invalid in various extents; 83.8% of samples from Guangdong area become invalid in the seal between the inside of fittings and tope of the core; 78% of the samples from Hebei and Guangxi areas are degraded. The composite insulators made by compression technology is poor in bonding between the housings and sheds and can be stripped easily by hand. Aimed at the poor sensitivity of the method defined in the standard to detect the interface performance, a new method is proposed to test the interface performance through detecting the variation of DC leakage current of samples before and after boiling.关键词
