微機(jī)型保護(hù)裝置是用于測量、控制、保護(hù)、通訊一體化的一種經(jīng)濟(jì)型保護(hù);針對(duì)配網(wǎng)終端高壓配電室量身定做，以三段式無方向電流保護(hù)為核心，配備電網(wǎng)參數(shù)的監(jiān)視及采集功能，可省掉傳統(tǒng)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(shù)據(jù)及保護(hù)信息遠(yuǎn)傳上位機(jī)，方便實(shí)現(xiàn)配網(wǎng)自動(dòng)化;裝置根據(jù)配網(wǎng)供電的特性在裝置內(nèi)集成了備用電源自投功能，可靈活實(shí)現(xiàn)進(jìn)線備投及母分備投功能。適用于110KV及以下電壓等級(jí)的保護(hù)、監(jiān)控及測量，可用于線路、變壓器、電容器、電動(dòng)機(jī)、母線PT檢測、備用電源自投回路及主設(shè)備的保護(hù)、控制與監(jiān)視。單元化的設(shè)計(jì)使其不但能方便地配備于一次設(shè)備，也可以集中組屏、集中控制。規(guī)范的現(xiàn)場總線接口支持多個(gè)節(jié)點(diǎn)協(xié)調(diào)工作，實(shí)現(xiàn)系統(tǒng)級(jí)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.
