避雷器泄漏电流检测方法分析与应用

Analysis and Application of Lightning Arrester Leakage Current Detection Methods

目前避雷器泄漏电流检测主要有TV二次法、220 V电源法,检测结果存在差异,通过对上述2种方法检测结果进行分析,总结出影响避雷器泄漏电流检测结果的因素包括厂家批次、安装环境、电压等级、测试原理等。对检测方法进行分析,得出避雷器泄漏电流受到周围带电体等多种因素影响,在实际测量中应科学合理调整校正角度。

At present,there are TV secondary method and 220 V power supply method to detect the leakage current of lightningarrester,which have different detection results.Throughthe detection results analysisof the above two methods,it is concluded that the factors affecting the detection results of the lightningarrester leakage current include manufacturer batch,installation environment,voltage level,testing principle,etc.By analyzing the detection method,it is concluded that the leakage current of lightning arrester is affected by many factors such as the surrounding charged body,and the correction angle should be adjusted scientifically and rationally in actual measurement.
