摘　　要：从馈电开关在煤矿井下供电系统的重要性入手,针对国内矿用低压馈电开关继电保护装置存在的问题,使用F2812作为处理芯片,同时引入光纤以太网作为通讯媒介。该系统能自动判断短路、过载、过压、欠压和漏电等故障并提供保护,具有通讯接口实现了继保装置和上位机之间的数据传输。经现场实际测试,各项指标均达到设计要求。From importance of feed switch in underground mine power supply system to start,and according to domestic mine low pressure feed switch relaying protection existing problems to use F2812 as a processing chip,while introduction of optical fiber Ethernet as communication medium.The system can automatically judgment short circuit, overload, over-voltage, voltage, leakage current fault and provide protection, has a communication interface to transfer data between device and PC.After actual test, all indexes meet requirement of design.
