氧化锌避雷器抗相间、空间干扰带电测试研究

Research on Interphase and Space Interference Electric Testing Technology for Zinc Oxide Lightning Arrester

对变电站内氧化锌避雷器及其周围导体进行三维建模,直接仿真计算氧化锌避雷器遭受的相间、空间干扰电流的幅值和相位,评估干扰源对氧化锌避雷器带电测试的影响大小,并在已有氧化锌避雷器带电检测技术应用成果的基础上,通过叠加原理,将此干扰电流滤除以得到氧化锌避雷器绝缘状态的真实信息,提高避雷器带电测试水平,为逐步开展的状态检修工作提供可靠的数据支撑。

this topic proposed within the substation on zinc oxide lightning arrester and the surrounding the conductor for 3 d model-ing, and the direct simulation of the zinc oxide lightning arrester to suffer , space interference current amplitude and phase, to assess the effect of interference sources of zinc oxide lightning arrester charged test size, and results in the existing zinc oxide lightning ar-rester charged detection technology application, on the basis of through the superposition principle, the interference current filter di-vided by zinc oxide lightning arrester insulation condition of real information , improve the level of lightning arrester charged test, to gradually develop the status of the repair work to provide reliable data to support.
