软起动综合控制器电流信号采集方法的研究

Study on current signal acquisition method of soft start controller

文章主要研究了矿用隔爆兼本质安全型交流电动机软起动控制器的电流信号采集电路,对软起动器的二次侧交流信号进行高速采样,利用均方根算法获取所需的电流参数。实验证明,采用该采样方法,提高了系统的总体性能。

The paper mainly studied the current signal acquisition circuit of the soft start controller for mine flame proof and intrinsic safe AC motor. High data acquisition was made on the twice side exchange signals of the soft starter. The mean square root algorithm was applied to pick up the required current parameters. The experiment showed that the application of the acquisition method could improve the overall performances of the system.
