摘要
国内外仑认的、有效检测氧化物避雷器性能的方法是使用有线方式从PT电压信号通过电阻电流方法或相角差进行检测，但在实际情况下，大多数变电站避雷器安装的位置使得电压信号很难被检测到。由于直接采用阻性电流法或相角差法对避雷器性能进行检测需要获得电压相位信号，而电压相位信号又不能直接从高压线路上获得，给使用传统的检测方法检测避雷器的性能带来困难，本文通过试验研究和理论分析，提出了采用基于场强法的非接触获得高压输电线路的电压相位信号方式检测避雷器的性能。并通过手持端远程读取数据。
Recognized oxide arrester at home and abroad, effective detection method is to use the wired way from voltage signal through the resistance current method or PT phase Angle difference detection, but most of the actual distance and the substation lightning arrester installation position, it is difficult to get the voltage signal. Due to direct the resistance current method or phase Angle difference method is adopted to test the performance of surge arrester need voltage phase signal, and voltage phase signals cannot be gotten directly from the high tension line the road.Using the traditional test method for testing the performance of the lightning arrester is difficult.Through the experimental study and theoretical analysis, the method of non-contact way for high voltage transmission line voltage and phase signalwas proposedbased on the field intensity. Anddata were readthrough the handheld remote
