氧化锌避雷器带电检测方法的研究

Research on Live Detection Method of Zinc Oxide Arrester

近年来,电力系统不断地建设发展,其可靠性和安全性也必须有所提高,而金属氧化锌避雷器试验中的停电预试验大多被带电检测取代。带电检测无需停电便可测得避雷器的全电流或其阻性电流分量,以此来诊断避雷器的性能。对比分析了几种带电检测传统方法及新兴方法,对推动氧化锌避雷器带电检测技术的革新意义重大。

In recent years,due to the continuous construction and development of the power system,its reliability and safety must also be improved,and the power outage pre-test in the metal zinc oxide arrester test is mostly replaced by live detection.The live detection can measure the total current of the arrester or its resistive current component without power outage,so as to diagnose the performance of the arrester.Several traditional and emerging methods of live detection are compared and analyzed,which are of great significance to promote the innovation of zinc oxide arrester live detection technology.
