摘　　要：文章介绍了一种便携式电网过电压记录系统,能满足在信号记录、存储和数据处理上的自动化,并能在电网中长时间连续稳定的工作。根据电网电压的波动而自动设置为快采与慢采,采用500ksps的采样转换速率,实现了对电网信息的高速采集。This paper introduced a kind of portable over - voltage auto recording devices for the electric power supply network. It not only can record, memorize and deal with power signal automatically, but also can work well in power system. According to voltage changing, its can set collection speed by itself. 500 ksps is adopted to achieve high speed collection of information of power network in this system.
