针对工矿设备中电机保护的现状,设计了基于单片机的自动监测电机保护系统,能够对电流、电压、电机温度等关键参数进行实时在线监测,对过流、欠流、三相不平衡、过欠压、漏电、过温等常见故障进行智能判断,对数据进行掉电存储,同时方便了故障排除及检修。 Aiming at the status quo of motor protection in industrial and mining equipment, an automatic monitoring motor protection system based on single chip microcomputer is designed. It can monitor real time on-line parameters of key parameters such as current, voltage and motor temperature, and over-current, under- Voltage, leakage, over-temperature and other common faults intelligent judgment, power-down data storage, and facilitate troubleshooting and overhaul.
