摘要
研制一个实时记录工频电源电压的记录仪,可提供和北京时间同步的时间信息,记录不少于30天的电压数据,数据可通过串口或U盘读出,由手持终端软件绘制出电压变化曲线,为供电系统的运行情况分析、设备故障分析以及事故处理提供有力的依据。
Designed a real-time power frequency voltage recorder,it provides synchronization with Beijing time,records the data of voltage not less than 30 days,and the data can be read by the serial port or U dish.The hand-held terminal can map out the voltage curve,it provides an efficient basis for power system analysis,equipment failure analysis and trouble removal.
