摘要
该文介绍了以 PIC单片机为核心 ,设计的一种智能型三相电机保护器 .其最大特点是使用了带 A/D转换模块的 PIC单片机 ,通过 A/D转换器的应用成功地实现了准确越过电机启动瞬间的电流动态变化期 ,正确地在电机工作电流稳定时采样电机的工作电流 ,并实现了电机缺相、过电流、欠电流、欠电压保护 .不仅电路简单 ,且使用简便、工作可靠 .
This paper introduces an intelligent protector for three phase motors which has the PICMCU as the core.It uses the PICMCU with the A/D change over module which helps to overcome the instant electric current dynamic changing period succesfully.The protector samples the working electric current of the motor correctly when the current is steady,and it can protect the motor when the motor has the problems of motor missing,overload electric,lack of electric or lack of voltage.This kind of protector not only has the simple circuit but also is convenient.
