摘要
本文主要介绍了基于芯片ATT7053A的符合国家最新标准的多功能电子式单相电能表的电路设计,并指出电路设计和在最后电能表校表过程中要注意的一些重要事项。该多功能电子式单相电能表采用段码式液晶屏显示,并能精确地测量有功电能、无功电能、有功功率、无功功率、电压有效值、电流有效值和功率因数等多参量,并依据预先设定的相应费率要求进行电能计量。
In this paper,a energy meter in accord with the new technical specification of the state grid based on the ATT7053A is illustrated.In the end,some important application notes about the electric circuit design and the course of the energy meter calibration are put forward.This energy meter applies LCD panel to display important data.It can measure active energy,reactive energy,IRMS,VRMS,power factor and so on.It also can measure the energy consumpution according to the set rate in advance.
