防雷接地设计作为站房电气设计的一部分,除了一般建筑通用的做法外,还有其特殊做法和要求。结合沪杭客运专线松江南站工程设计实例,总结了铁路站房防雷接地的做法。指出铁路站房的综合防雷系统需要采取内外结合的形式,信号机房需要落实屏蔽和等电位联结的措施,整个站房通过等电位联结而形成联合接地,能够有效防止雷电危害。
Lightning protection grounding design as part of the electrical design of the station, in addition to general construction practices, but also its special practices and requirements. Combined with the Shanghai-Hangzhou Passenger Dedicated Line Songjiang South Station project design examples, summed up the railway station room lightning grounding practices. It is pointed out that the integrated lightning protection system of railway station house needs to take the form of internal and external combination. The signal room needs to implement the shielding and equipotential bonding measures. The whole station house forms a united ground through the equipotential bonding and can effectively prevent the lightning damage.
