随着我国电气化铁道运营里程的增加、重载及高速铁路的快速发展，评价接触网的防雷性能、减少接触网发生雷击故障具有重要的理论意义和工程应用价值。
With the increasing of running kilometer in electrization railway and the fast development in our country , evaluating the lightning protection performance of catenary and reducing stroke-incidence in catenary are very important questions either in theory or in practice .
