地铁站台门绝缘问题解决对策

Development and New Solutions for Solving the Problem of Insulation of PED

地铁站台门的绝缘问题涉及多方面,包括站台门本身绝缘结构设计、站台绝缘层的方案及施工、站台其他专业的接口和施工管理以及等电位连接理论等。从这些方面深入剖析现行地铁站台门在实际工程中的绝缘问题,对最新的包括站台门绝缘结构优化、绝缘喷涂技术等各种绝缘方案进行综合分析,结合实际工程项目实施,提岀复合绝缘地槛结合门体涂刷绝缘材料的新型绝缘方案,方案中站台门主体承重结构基本保持不变,主要聚焦于绝缘问题本身,着重解决地槛既要耐磨又要绝缘的难点。

The insulation problem of platform edge doors(PEDs)involves many aspects,including the insulation structure design of the PED itself^equipotential connection theory,etc.After in-depth analysis of the causes of existing insulation problems and the latest insulation schemes,based on actual project implementation,a new insulation solution for composite insulation threshold based on insulation material coating on the door frame is proposed.The new solution not only focuses on the problems to be solved but also avoids the creation of new problems,and strives to promote reliable technological progress.
