【摘要】 本文介绍了一种带通信的多功能智能型磁力起动器。该磁力起动器利用单片机对交流接触器的起动过程、吸持过程、分断过程进行控制,提高了接触器的电寿命。而且该起动器具有电动机过压、欠压、堵转、过载、不平衡、断相保护等功能特点,能够实时显示电动机的线电压、三相电流,并可以实现与主控计算机的双向通信。更多还原

【Abstract】 A kind of intelligent magnetic starter was introduced in this paper. It can control the starting, maintaining and opening of the AC contactor. The function of protector was to protect the motor when it was in the state of over-voltage, under-voltage, jam, overload, unbalance and phase failure, it can also display the line voltage; three phase current of the motor. Moreover, the intercommunication between the protector and PC was realized.更多还原
