城市轨道交通站台门门槛绝缘方案研究

Research on the Insulation Scheme of Urban Rail Transit Platform Door Threshold

针对现行地铁线路站台门门槛的结构局限性,从站台门门槛绝缘失效的原因及安装方式出发,探讨了传统站台门门槛绝缘失效的原因。结合生产安装的实际情况,提出了3个站台门门槛绝缘新方案。这些新方案未对现有站台门门体结构作大的变动,具有良好的经济性。经过理论验证和工程化试验验证,新方案绝缘效果良好,施工便捷。

According to the structural limitations of current metro station door,reasons for traditional station door threshold insulation failure and the installation problems are discussed.Combined with the actual installation,three station door threshold insulation schemes are proposed,which have good economy with only limited changes of the present door structure.Through theoretical and engineering tests,the new insulation schemes are proved to have good performance and construction convenience.
