一种应用于制盐业电机的智能保护系统

An Intelligence Protection System Applied in the Motors Used in Salt Making Industry

介绍了一种用于制盐业三相交流电机的电流、电压和温度的智能保护系统的设计与实现。当检测到欠压、过压、过流、电流和电压不平衡、绕组温度过高和单相运行情况时,系统经过单片机8098的控制就会切断输入的三相电源,并在报警的同时显示故障的类型。

This paper introduces the design and practice of intelligence protection system for the current,voltage and temperature of three-phrase AC motors.When undervoltage,overvoltage ,overcurrent, imbalance between current and voltage,excessively high temperature of winding and single phasing are detected,the system will cut off the input three-phase power spply through the control of single chip 8098 and display the type of failures at the same time of alarm.
