摘要
在悬式瓷绝缘子串电压分布及发热特征基础上进行了讨论,分析了红外成像测温法和火花间隙法等常见检测劣化绝缘子方法的工作原理,对悬式瓷绝缘子低(零)值带电检测进行了模拟试验,对比分析了红外成像测温法和火花间隙法对低(零)值绝缘子检测的有效性和准确性,总结了变电站绝缘子劣化检测的方法和措施。
Based on the study of voltage distribution and heat generation characteristics of suspended porcelain insu- lators, the paper analyzes the mechanisms of common methods for detecting faulty insulators, such as infrared imaging method, and spark gap method, etc. Besides, it also simulates the live detection of low-resistance （zero-resistance） suspended porcelain insulators, compares the effectiveness and accuracy of the above said methods, and summarizes the methods and measures for detecting faulty insulators in substations.
