摘要
无功补偿用电容器避雷器因长期承受操作过电压的应力,损坏率较高。通过分析与无功电容器配合使用的避雷器特点,指出现有在线监测技术的局限,尤其是沿用普通工频避雷器监测表的测量弊端,分析了具体的原因,提出了一种基于三次谐波法以及谐波滤波方案的离线型带电检测技术,实践证明其应用效果较好。
The capacitor arrester for reactive power compensation has a high damage rate because of the long-term stress of operating overvoltage. For the arrester used in conjunction with reactive power capacitor, this paper points out the limitations of the existing on-line monitoring technology, especially the disadvantages of measuring with common power frequency arrester monitoring meter. It analyses the specific reasons and puts forward a new type of off-line live detection technology based on the third harmonic method, which has been proved to be effective in practice.
