摘要
城轨交通以其快捷、准点、运输能力强等优点,近年来得到快速发展。由于其涵盖的专业多,各系统设备都要接地,这给综合接地系统设计带来更高的要求。此文针对直流和交流牵引供电系统实际,对地铁车站接地系统的构成、接地方式、接地体的埋深,以及与土建工程的结合等进行探讨,提出有关综合接地方案。
Urban rail transit has developed rapidly in recent years because of its advantages such as shortcut, punc- tuality and strong transport capacity. Because it covers a large number of specialties, and every system e- quipment must be grounded, which brings higher requirements for the design of integrated grounding sys- tem. According to the actual situation of DC and AC traction power supply system, the composition, grounding mode and buried depth of grounding system of subway station are discussed. The combination of grounding system and civil engineering is analyzed. And the comprehensive grounding scheme is put forward.
