The microcomputer protection device is an economical protection which is used to integrate measurement, control, protection and communication. It is customized for the high voltage distribution room of the distribution network terminal, with the three-stage directional current protection as the core, equipped with the monitoring and collection function of the grid parameters, which can save the traditional ammeter, voltmeter, power meter, frequency meter, kilowatt-hour meter, etc., and can transmit the measurement data and protection information to the upper computer through the communication port, which is convenient to realize the automation of the distribution network. According to the characteristics of power supply in the distribution network, the function of the standby power source is integrated in the device, which can flexibly realize the functions of incoming line backup and female sub-backup. It is suitable for protection, monitoring and measurement of 110KV and below voltage levels, and can be used for line, transformer, capacitor, motor, bus PT detection, backup power source circuit and main equipment protection, control and monitoring. The unit design makes it not only convenient to be equipped with a primary device, but also can be centralized group screen and centralized control. The standardized fieldbus interface supports the coordination of multiple nodes to achieve system-level management and comprehensive information.
