基于TSC测试的硅橡胶复合绝缘子伞裙材料老化特性研究
Study on Aging Characteristics of Silicone Rubber Sheds of Composite Insulators Based on TSC Test
摘要
Abstract
In order to assess the aging characteristics of composite insulators based on the thermally stimulated current (TSC) test, the composite insulators in service were studied using the TSC test and the HC water spray hydrophobicity test. The influences of several aging factors on the shed materials of composite insulators in service such as shed locations, operating years and environment contamination levels were considered. It is found that the peak current of test samples and the corresponding trap charge amount of the TSC curve are larger under the following situation: samples from the location where the electric field of the insulator string is higher; and samples from the insulators with a longer operating life or working in seriously polluted areas. By comparative analysis of these two test methods for evaluating the aging degree of insulator sheds, it is found that the TSC test can distinguish the different aging degrees of the shed materials of composite insulators more clearly and has more advantages in aging characteristics evaluation.关键词
