摘要
介绍一种基于MSP430F449单片机的智能同步开关控制系统,该系统通过对电网的相电压、相电流进行采样,利用过零信号控制高压开关接通和断开的时间,使得开关的主触头分别在电压的过零点附近合上,在电流的过零点附近断开,消除容性负载的浪涌电流和感性负载的感应电压。
This article introduces the application of MSP430F449 microcontroller in the control system of intelligent synchronous vacuum switch.this system can control turn-on and turn-off time of the high voltage switch making use of the zero-pass signal and by adopting phase voltage and electric current of the electrical network.,it can be connected when the voltage is zero and it can be broken away when the electric current is zero. then it can eliminate the wave-like electric current with capacitive load and the inductive voltage with inductive load .this system can also figure out the effective number of phase voltage and electric current and power factor,monitoring the run parameter of the electrical network anytime.
