500 kV氧化锌避雷器电阻片温度分布特性研究
|
摘要
氧化锌避雷器是电力系统中的重要设备之一,其性能的好坏直接影响到电网的安全稳定运行。为了能够有效监测氧化锌避雷器的运行状态,及时发现氧化锌避雷器的缺陷故障,避免重大事故的发生,文中对500 kV氧化锌避雷器进行了不同位置受损及受潮情况下的升温试验,分析了500 kV氧化锌避雷器在各种运行工况下的温度分布特性。试验表明:氧化锌避雷器单节电阻片击穿受损时,温升速率最显著的是其相邻避雷器节;氧化锌避雷器电阻片受潮时,受潮位置的温升速率最快、幅值最高。试验所得结论为通过温度判据进行避雷器故障诊断提供了真实数据,同时也为避雷器的状态评价提供有力依据。
The purpose of this study is to effectively monitor operation status of zinc oxide arresters, find their defects in time and avoid major accidents. Elevated temperature test was conducted for the 500 kV zinc oxide arrester with damage and damp at different position. The temperature distribution characteristics of the arrester were analyzed under different working conditions. Test results showed that when the resistance sheet of one arrester node was broken down the most significant temperature rise appeared at the adjacent arrester node, and the damped position of the resistance sheet exhibited the highest temperature rise rate and amplitude.
