摘　　要：本文介绍了一种基于MCU控制核心的输电线路杆塔突发电流监测器,较为详细地论述了其工作原理、硬件结构和软件设计。该监测器通过杆塔上的电流互感器获取故障电流信号,利用信号调理电路和MCU对故障电流进行高速采样和存储控制,实现故障电流的在线监测,同时通过实时时钟模块为每个故障电流到达时间定标,通过射频通讯模块将监测到的故障电流信息发送到站置机服务器中,本产品已在贵州六盘水供电局投入使用,结果证明具有很高的实用价值。In this paper,a core-based MCU to control the transmission line tower sudden monitors current monitors, and a more detailed discussion of its working principle,hardware structure and software design are prsented. Through the current transformer,the monitor obtains tower lightning current signal,and by using signal conditioning circuit and MCU,it can realize high-speed sampling and storage control,the realization of fault current on-line monitoring,real -time clock module through fault current for each arrival time calibration.Through the RF communication module it will monitor the fault current to the reliability of the information sent home server machine. This product has been in put into use in Liupanshui in Guizhou Power.The results prove that it has high practical value.
