摘要
针对ＺｎＯ避雷器泄漏电流的在线检测问题，从测试方法和测试手段２个方面对目前的测试仪状况进行了分析．在信号的取样环节方面，提出了一种采用光电隔离传输电路作为取样环节的方案，不仅能满足测试仪与主电路间电气隔离的要求，同时能较好地跟踪避雷器泄漏电流波形。
For the problem of monitoring the state of the Zinc oxide surge arrestors,this paper analyses and discusses the current conditions of the instruments in the respects of measuring ideology and measuring methods.A leakage current sample method based on an optic electronic transmitting and isolating circuit is proposed. This sample not only can isolate the system and the instrument electrically,but also can transmit the analogue signals linearly.
