Lightning Damage and Lightning Protection Effectiveness of Overhead Ground Line on 10 kV Lines in Beijing Area
摘要
Abstract
In order to clarify the lightning damage and the lightning protection effectiveness of overhead ground line of 10 kV line in Beijing area,the author carries out simulation calculations of direct lightning stroke flashover rate and induced lightning stroke flashover rate for 10 kV overhead lines installed with o-verhead ground lines based on the lightning ground flash statistics from 2013 to 2022 in Beijing.Through quantitative analysis,the influence of three key parameters,namely,conductor and ground spacing,soil resistivity and tower frequency grounding resistance,on direct lightning stroke flashover rate,induced lightning stroke flashover rate and lightning stroke flashover rate of 10 kV overhead lines is obtained,and then a proposal for the configuration of overhead ground line in Beijing area is given.The research results can provide technical support for the application of lightning protection for overhead ground line of 10 kV line in Beijing area.关键词
