电力系统中多功能电力仪表的设计

The Design of Multi-functional Power Meter in Power System

针对电力系统中广泛应用的交流电力采集仪表存在的采集精度不高,采集范围不宽,受环境影响比较大等问题.设计出了一种采集变比可以任意设定,具有温度补偿功能的宽范围电力采集仪表.经试验验证得到,该仪表具有采集范围宽,适应环境能力强,采集精度高等特点,可以广泛应用在各种场合.

In view of the problems existing in AC power acquisition meter in power system,such as low acquisition accuracy,narrow acquisition range and large environmental temperature impact,the power acquisition meter with temperature compensation function and variable ratio setting and acquisition wide range is designed.The results of experiment show that the meter has the characteristics of wide acquisition range,strong adaptability to the environment,and high acquisition accuracy,thus it can be widely used in various occasions.
