地铁车站机电设备综合接地系统的分析及探讨

Analysis and Discussion on Comprehensive Grounding System for Electromechanical Equipment at Subway Station

地铁车站空间狭小、机电设备种类繁多、数目庞大。为保证人身安全和设备的安全、可靠运行,地铁车站机电设备综合接地系统在满足强电、弱电专业及其他非电气金属管道全部接地的同时,降低地铁车站内的接触电压、跨步电压、设备的对地电压,防止过电压、静电以及电磁感应的影响。针对地铁车站设备接地要求,对地铁车站接地系统进行分析和探讨。

The subway station has small space, a great variety and a large number of electromechanical equip- ments. In order to guarantee personnel safety and safe and reliable equipment operation, comprehensive grounding system for electromechanical equipment at subway station could not only meet the whole grounding of strong cur- rent, weak current and other non -electric metal pipelines, but also reduce the voltage to ground of contact volt- age, step voltage and equipment within the subway station to prevent the influence of overvohage, static electricity and electromagnetic induction. According to the grounding requirement for the equipment at the subway station, grounding system of the subway station is analyzed and discussed.
