太原地铁2号线综合接地系统设计

Design of Integrated Grounding System for Taiyuan Metro Line 2

简介地铁综合接地系统的组成,对地铁综合接地系统强弱电设备接地、接地母排、LEB箱、站外落地式导向牌接地、接地电缆的设计要求进行阐述。依据GB 50157-2013《地铁设计规范》要求,以太原地铁2号线车站为例,对地铁综合接地网的设计进行探讨,提出地铁地下车站综合接地设计方案。

The composition of the integrated grounding system of the metro line is introduced briefly and the design requirements for the grounding of strong and weak current installations, the grounding bus-bars, the LEB cabinets, the grounding of floor-type indication signs and the grounding cables of integrated grounding system of the metro line are described. According to GB 50157- 2013 Code for Design of Metro, Taiyuan Metro Line 2 is taken as an example to discuss the design of the integrated grounding grid of the metro line and a design scheme for the integrated grounding of underground stations is proposed.
