Abstract
The corridor Chongqing Jingtang Line 10kV line is terrain,along the route with chemical park and there are several lines across the valley and the river caused the larger span,the fault of mine-affected is serious.Through the on-site investigation of the point of the whole line which is vulnerable to lightning and the lightning protection of distribution transformers,analysis the lightning disturbance-prone reasons such as the effects of lightning from the topography,contamination reduce the level of Insulator insulation and the lightning problems of the distribution transformers,etc.On which basis proposed erecting the ground coupling,installing the protection gap,improving the distribution transformer lightning protection measures and so on,thus improving the mine-resistant level of the line,which ensures the reliability of the power distribution.关键词
