摘　　要：基于GPS授时技术设计了网络同步采集卡,进行高压交流输电线路电晕信号的测量。采集卡采样频率可达每通道10 MS/s,使用TCP/IP协议进行数据传输;可介入局域网或互联网。利用瞬时功率法对高压输电线路的电晕损耗进行分析计算,使用首端电阻法对薄膜电阻法测量电晕损耗的可行性进行了进一步验证。实验结果表明,系统抗干扰能力强,能获得电晕放电信号的细节信息,实用性较强。The network synchronization acquisition card is designed based on GPS timing technology, to measure the corona signal of the high voltage AC transmission line. Acquisition card sampling frequency is up to 10 MS/s, using the TCP/IP protocol for data transmission and can be involved in the local area network or the Internet. Using instantaneous power method to analyze and calculate the corona loss of high voltage transmission lines, the feasibility of measuring corona loss is verified by using the first method. The experimental results show that the system is able to obtain the detailed information of the corona discharge signal, and the system is more practical.
