摘要
氧化锌避雷器在电网中有着重要的作用,带电测试运行电压下的全电流、阻性电流、相位角能直接反映避雷器的运行状况,方法简单,数据准确。对氧化锌避雷器带电测试的原理及方法进行了分析研究,介绍了常用的几种电压采样方法。对测试结果的判断提出建议。
Zinc oxide arrester plays an important role in the power grid.The full current,resistance current and phase angle under the running voltage of living test could directly manifest the running state of the arrester,characterized by simple method and accurate data.This paper analyzes and studies the principle and methods for zinc oxide arrester,and introduces the common several voltage sampling methods,then proposes suggestions about the judgment of the testing result.
