长沙磁浮快线工程的防雷接地设计要点

磁浮快线的车体构造、轨道结构和受流方式与其他轨道交通方式明显不同,因此在防雷接地设计方面需要特殊考虑。介绍了长沙磁浮快线车站、高架区间、车辆段防雷及接地网的设置方式、使用材料及相关材料,详细说明了接触轨、F型轨道及弱电系统的防雷接地设计方案,着重介绍了区间及F型轨道防雷接地的具体做法及土建预留预埋的要求。经实际使用验证,长沙磁浮快线的防雷接地设计,取得了较好的防雷效果。

Design of Lightning Protection and Grounding for Changsha Maglev Express Project

There are significant differences between maglev train and other rail transit means in car-body structure,track structure and current collection mode,special consideration should be paid to the design of lightning protection and grounding.In this paper,the setting mode and materials of lightning protection and grounding facilities for Changsha maglev express station,elevated section and depot are introduced,concrete practices of the design are described.In the form of diagram,lightning protection and grounding solutions,the civil reserve requirements of embedded construction in the interval and F-type track are also introduced.These design schemes and solutions have been used in Changsha maglev express project with good lightning protection effect,providing a valuable reference for the design of similar oroiects in the future.
