【摘要】 针对目前国内生产的电压监测仪只能对某一个测试点进行监测、实时采集的数据只保存在 EEROM中、统计数据有限的问题 ,介绍一种对电压质量进行记录的智能化电压监测仪 ,可实现多个回路同时监测 ,并有统计电压最大值、最小值 ,电压合格率 ,按时间查询 ,观测各测试点日电压曲线 ,打印月报表、日报表等功能。该系统已安装在湖南树木岭变电站。更多还原

【Abstract】 At present the domestic voltage monitoring instruments can only monitor one certain point, the monitored data must be saved in EPROM and the monitored data is limited in number. In this paper an intelligent voltage monitoring instrument is presented, which can monitor several circuits simultaneously and possesses such functions as carrying out the statistics of eligible rate, maximum and minimum values of voltages, querying the monitored data according to specified time, inspecting daily voltage curve of each monitored point, printing monthly and daily report. This instrument has been installed in Shumuling substation, Hunan province.更多还原
