Google Earth在输电线路防雷中的应用

介绍了Google Earth在输电线路防雷中的应用情况。利用Google Earth直观显示雷击故障杆塔三维地形情况,在此基础上对雷击典型地形进行分类汇总;结合Google Earth的测量距离和新增坐标位置功能,对雷电定位系统杆塔经纬度坐标进行核对,同时在发生雷击故障时,将雷电定位系统查询的杆塔范围和Google Earth显示的地形地貌相结合,进一步减小巡视杆塔范围;用Google Earth直观显示海拔高度的功能,对输电线路杆塔所在位置的地面倾角进行定量求解。

Application of Google Earth in Lightning Protection of Transmission Lines

The article elaborates application of Google Earth in lightning protection of transmission lines： Google Earth is adopted to provide three-dimensional view of the topography where there are poles and towers with lightning faults,on the basis of which the typical topographies are aggregated in line with categories;By combining the measured distance and newly-added function of coordinate location,latitude and longitude coordinates of poles and towers in lightning location system will be verified.When lighting faults occur,the range of poles and towers inspected by ligntning location sytem will be combined with topography shown by Google Earth to further minish inspection scope of poles and towers.The angle of ground at the place of poles and towers of transmission lines can be quantitatively calculated by exerting elevation display function of Google Earth.
