随着轨道交通不断向地面、高架区间延伸,轨道交通的直击雷防护也成为一项新课题。通过分析轨道交通可能遭受的雷电危害,着重对轨道交通的直击雷进行分析,并提出通过提高架空地线及提高护栏顶部接闪器的方法,对轨道交通进行保护,可供类似项目的防雷设计者参考。 As rail transit continues to extend to the ground and overhead areas, direct lightning protection in rail transit has also become a new topic. Through the analysis of the lightning damage that the rail transit may suffer, the paper analyzes the direct lightning of the rail transit and proposes to protect the rail transit by raising the overhead ground wire and improving the lightning receptor on the top of the parapet, so as to provide lightning protection for similar projects Designer’s reference.
