轨道交通屏蔽门接地研究

摘要

The impact of rail potential on operators and passengers is analyzed according to the effect of direct current when flowing through human body. Recommendations that the rail transit shield door system shall comprehensively adopt TN - S earthing system and measures for further reducing the current flowing through human body are proposed. This solution solves the construction difficulty in insulating installation of platform shield door based on guaranteeing personal safety, and eliminates current hidden dangers of igniting and burning of shield door components.%从直流电流通过人体时的效应着手，分析轨电位对运营人员和乘客人身安全的影响，提出轨道交通屏蔽门系统全面采用TN-S接地系统的建议方案和进一步减小通过人体电流的措施，该方案在保证人身安全的前提下，解决了站台屏蔽门绝缘安装的施工难题，消除了目前屏蔽门构件打火、燃烧的隐患。
