| 摘 要： | 基于短距离无线通信的便携式氧化锌避雷器在线测试仪由高压钳型电流传感器模块、绝缘操作杆和便携式主机三部分组成。高压钳型电流传感器模块夹在避雷器高压端或接地端，将采集到的泄漏电流信号调理放大，转化为数字信号，通过无线通信的方式将采集的信号传输到便携式主机；便携式主机通过无线方式接收高压钳型电流传感模块传送的数字信号，进行分析计算，得到氧化锌避雷器阻性电流的三次谐波含量，通过分析判断给出氧化锌避雷器的老化程度。

| Abstract: | This paper introduces a portable testing instrument for the Zinc-Oxide Surge Arrester. The high-voltage pliers-shape current transducer module clips on the high-voltage side or the earthing end of the ZSA to collect the small leakage current signal from ZSA. The data of the leakage current is then transmitted to the host processor by the wireless means. Based on the analysis of the third harmonic wave of leakage current, the aging degree of ZSA is thus obtained. |
