| 摘 要： | 污秽绝缘子的泄漏电流是表征绝缘子表面状态的重要动态参数.污秽绝缘子泄漏电流特性以及基于泄漏电流特征量的污秽度预测、闪络风险评估一直是国内外相关领域学者研究的热点,但泄漏电流的统计特性和闪络风险的定量计算的研究很少.为此,在人工搭建的雾室内,对XP-160和LD-120绝缘子进行大量人工污秽试验,以泄漏电流幅值Im和闪络...

| Abstract: | A lot of artificial pollution tests were experimentally investigated in the fog chamber for two kinds of insulators,XP-160 and LD-120 insulators,a large number of test data were obtained,and flashover risk comprehensive assessment based on leakage current amplitude(Im) and flashover voltage(Uf) of polluted insulators was also established.The results show that: probability functions of both amplitude of leakage current(Im) and flashover voltage(Uf) can be described with the normal distribution.Statistical ch... |
