基于光学成像的铁路站场闪电监测技术研究与实现

Research and Implementation of Lightning Monitoring Technology in Railway Stations and Yards Based on Optical Imaging

针对当前铁路系统中由于缺乏对站场内闪电活动的有效监测手段,闪电击中地面设备时无法得到确切的雷击位置,雷害事后处理困难的问题,研制了一种适合铁路站场的光学闪电监测设备,用于小范围内设备密集区域的地闪监测,并记录闪电发生的过程。详细介绍该设备的结构组成、工作流程和架设方法,并通过人工触发闪电试验对该设备进行了验证,可为雷害事故后续的故障寻因和雷害分析提供参考和依据。

In view of the lack of effective monitoring means for lightning activities in the railway system now,the exact lightning strike position cannot be obtained when lightning strikes ground equipment,and it is difficult to deal with lightning damage afterwards,an optical lightning monitoring device suitable for railway station is developed,which is used for ground lightning monitoring in a small area with dense equipment and recording the lightning occurrence process.The system composition,work flow and erection method of the device are introduced in detail.The device is verified by the artificially triggered lightning experiment.The device can provide reference and basis for subsequent fault cause finding and lightning damage analysis of lightning accidents.
