摘　　要：随着电网的快速发展,高压电气的绝缘性能决定了电网可靠性及稳定性,对操作过电压进行采集和分析是科研人员评价高压电气绝缘性能的重要指标之一。针对传统利用示波器方法依赖于有线方式进行波形采集,存在连接测试线繁琐、接地端不良时易发生触电等问题,设计了以兆易创新GD32位微型计算机为核心,基于Zigbee 3.0无线传输技术的操作过电压采集分析系统,解决了原始波形信号在高压电场环境下传输过程中易受外界干扰导致信号失真的难题。依据操作过电压采集结果开展绝缘性能分析,为高压电气设备防雷接地性能评估及电网规划提供一定参考。With the development of power grid,the insulation performance of high voltage electric power system determines the reliability and stability of power network.The acquisition and analysis of operating overvoltage is one of the important indexes for researchers to evaluate the high voltage electrical insulation performance.According to the traditional oscilloscope method relies on the wired method for waveform acquisition,which has some problems such as cumbersome connection test line and electric shock when the ground end is bad.It designs an operating overvoltage acquisition and analysis system based on Zigbee 3.0 wireless transmission technology,which is based on Zhaoyi Innovation GD32-bit microcomputer.The method solves the problem that the original waveform signal is easy to be distorted by external interference in the transmission process under the environment of high voltage electric field.The insulation performance analysis is carried out based on the data collected from the operating overvoltage,which provides some reference for the evaluation of lightning protection and grounding performance of high voltage electrical equipment and power network planning.
