摘要
介绍了单相多功能电能计量芯片71M6521的基本功能和特点。在此基础上,设计了计量精度高、工作稳定、成本相对较低的数字单相多功能电能表,以实现对三相电流、电压,有功、无功功率,电能脉冲的输出等的计量。该数字单相多功能表可用于电力系统、工矿企业、智能大厦的电力监控。
The basic function and feature of single phase multi-function electric energy measurement chip 71 M6521 were introduced. The digital single phase multi-function electric energy meter of high-precision measurement, stable running, relatively lower cost, was designed, and the measurement of three-phase current, voltage, active and reactive power and the output of electric pulse were realized. It could be used for the power monitoring of the power system, industrial and mining enterprises, intelligent building.
