摘要：Trip to cope with the lightning strike caused around power grid, this paper proposed a transmission line based on the mechanism of lightning strike around all lightning strike tripping around risk analysis methodThis method needed to detour lightning tripping thunderstorms and risk analysis of transmission lines tower size, proportion of topography, altitude, insulation configuration data were collected, calculated in turn hit distance, distance and exposure correction of line pressure level and single-base tower above factors lightning strike riskBased on the calculation model, the lightning wind characteristics under different tower shout height, lightning day and terrain were studied to identify the weak links along the lineSelect the composition condition calculation of typical tower lightning strike tripping around risk, based on the same area across the terrain and tower usage of extract weight coefficient calculation all lightning strike tripping around risk, through the typical combination of the weighted average of all lightning strike tripping around risk was analyzedThrough the example analysis, verified the feasibility of this method to improve the reliability of transmission lines.
