微機型保護裝置是用于測量、控制、保護、通訊一體化的一種經濟型保護;針對配網終端高壓配電室量身定做，以三段式無方向電流保護為核心，配備電網參數的監視及采集功能，可省掉傳統的電流表、電壓表、功率表、頻率表、電度表等，并可通過通訊口將測量數據及保護信息遠傳上位機，方便實現配網自動化;裝置根據配網供電的特性在裝置內集成了備用電源自投功能，可靈活實現進線備投及母分備投功能。適用于110KV及以下電壓等級的保護、監控及測量，可用于線路、變壓器、電容器、電動機、母線PT檢測、備用電源自投回路及主設備的保護、控制與監視。單元化的設計使其不但能方便地配備于一次設備，也可以集中組屏、集中控制。規范的現場總線接口支持多個節點協調工作，實現系統級管理和綜合信息共適用范圍。

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.
