继电保护辅助设备智能监测系统研究

对继电保护辅助设备检测方法进行研究，提出了一套继电保护辅助设备智能监测系统。利用物联网新型传感器、LPWAN和数据智能分析等技术，实现了压板及转换开关位置、户外箱柜内环境等继电保护辅助设备的状态实时感知、自动巡视、异常预警和数据共享等功能。研究结果表明，所提出的监测系统能够有效消除因压板及转换开关错漏投、端子箱凝露积水等原因造成的电网运行重大安全隐患，有效降低运维人员日常巡视的工作量，缓解巡视工作量与运行班组承载能力之间的矛盾。

Research on Intelligent Monitoring System of Relay Protection Auxiliary Equipment

The detection method of relay protection auxiliary equipment is studied, and a set of intelligent monitoring system of relay protection auxiliary equipment is proposed. By using new sensor of Internet of things, LPWAN, data intelligent analysis and other technologies, real-time state perception, automatic inspection, abnormal warning, data sharing and other functions of auxiliary relay protection equipment, such as the position of pressing plate and transfer switch, and the environment inside outdoor cabinet, are realized. The research results show that the monitoring system proposed can effectively eliminate the major hidden dangers of power grid operation caused by the fault and leakage of pressure plate and transfer switch, condensation of terminal box and water, effectively reduce the daily inspection workload of operation and maintenance personnel, and alleviate the contradiction between inspection workload and the carrying capacity of operation team.
