摘　　要：分析地铁车站施工临时用电实施过程中存在各种问题。西安地铁4号线某站施工时,临时用电中存在供电方案选择、负荷末端电压损失、二级箱配置、漏电保护配置和开关箱接地等问题。在用电安全第一原则的前提下,通过优化设计方案、并联电容器等措施,减少了用电元器件和电缆材料等投资。There are various problems during the implementation of temporary electricity in subway station construction. The paper takes Xi'an metro line four as an example, and analyzes the choice of the power supply, loss of load terminal voltage、the second-level box configurationleakage protection configuration switch box grounding and other issues in the power supply process. Under the premise of the first principle of electricity safety, through the optimization of design programs, shunt capacitors and other measures,as much as possible to reduce investment of electrical components and cable materials.
