沈阳地铁车站降压变电所设置方案研究

Research on Step-down Substation Setting Plan for Shenyang Subway

降压变电所的位置和设置方式对地铁车站的土建规模和供电系统的投资有很大影响。本文结合沈阳地铁一号线一期工程典型车站的土建结构和动力照明用电负荷的分布情况,通过经济技术分析、比较,深入研究地铁车站降压变电所的设置方案,在保证功能的前提下,达到合理利用资源,节约土建和供电系统投资的目的。

The position and location of service substation have great influence to the architecture dimensions and the power supply system＇s investment of underground station. According to the architecture structure and the power and lighting loads distributing of Shenyang section 1 line 1 typical underground station, this paper proposes a project of service substation location by analysis of investment and technology. Based on function, the project can make good use of resource and economize the investment of the architecture and the power supply system.
