基于单片机控制的地震台站交流电保护系统的研发

Research on AC Power Line Protection System of Seismic Stations based on SCM

针对地震台站交流电的故障问题,开发了一套保护系统。该系统利用单片机采集地震台站供电线路的温度、电压、电流等数据,分析、判断出供电线路的状态,及时给出继电器的相应命令来控制供电线路的接通或关闭。通过自动判断、自动恢复或关闭线路来降低线路故障,减少故障停电时间,提高地震台站的运行效率。

Aiming at the troubles of seismic stations＇ AC power line,this study focuses on developing a set of protection system.The system collects and analyzes the temperature,voltage,and current data of power line using SCM.Then the states of power supply line are utilized to trigger the electrical relay to switch on or shut down the power in time.The system can offer the benefits of less power line troubles and decreased time of power off by judgement,recover or shuting automatically,and improve the operating efficiency of seismic stations.
