三相电源相序检测的仿真分析

Simulation Analysis on Phase Sequence Detection of Three-phase Power Supply

文章利用仿真软件对该相序指示器电路进行仿真,以图形的形式输出各信号分量的波形、有效值和相位信息。最后给出了相序指示器的测试电路,通过操作按钮来检测相序,从而降低了实验触电的危险。该方法有助于学生理解三相电源相序检测原理。

In this paper,the simulation software is used to simulate the phase sequence indicator circuit and output the waveform,effective value and phase information of each signal component in the form of graph.Finally,the test circuit of the phase sequence indicator is given,which can detect the phase sequence by operating the button,so as to reduce the risk of electric shock.This method is helpful for students to understand the phase sequence detection principle of three-phase power supply.
