摘　　要：主要介绍一种新型的三相四线电能表的设计方案,该方案采用了三相电能测量芯片SA9904和Microchip的PIC16F77作为核心器件。本文所设计的电能表不仅可以测量三相有功无功电量,而且可以分别测量三个单相有功电量,并且通过6位LED数码管,实现三相有功无功电量和三个单相电量的循环显示。The design of a new type of three-phase and four route energy meter was introduced. Three-phase energy measurement IC SA9904 and Microchip＇s PIC16F77 are adopted in this design as core devices. This energy meter not only can measure the three-phase active and reactive energy but also can respectively measure the three single-phase active energy. Furthermore, it implement circle display of the energy and single-phase active energy with 6-bit LED.
