摘　　要：地铁作为缓解城市系统地面交通压力的有效措施之一,得到了我国政府的高度重视,我国的地铁运输建设事业也得到了快速的发展,各大城市都在纷纷建设一个完整的地铁运输系统,但在地铁工程建设的过程中,电力是一个不可缺少的重要施工资源。并且在建筑技术不断更迭换代的影响下,施工所用的各类用电设施数量也在不断的增加。但是由于地铁施工现场的临时用电设备负荷波动数值往往相对较大,同时电气设备的工作环境也相对较为恶劣,这也就导致会出现一定的用电安全问题。在这种情况下,为了确保地铁施工临时用电系统的稳定安全运行就需要对其用电负荷进行精确的计算,并选择最为合适的临时用电设备来确保整体的用电安全。As one of the effective measures to relieve the pressure on the ground transportation of the urban system,the subway has been highly valued by the Chinese government.China’s subway transportation construction has also been rapidly developed.Major cities are building a complete subway transportation system.But in the process of subway construction,electricity is an indispensable important construction resource.And under the influence of the continuous change of construction technology,the number of various electric facilities used in construction is also increasing.However,because the load fluctuation values of temporary electrical equipment at subway construction sites are often relatively large,and the working environment of electrical equipment is relatively harsh,this also leads to certain electrical safety issues.In this case,in order to ensure the stable and safe operation of the temporary electricity system for subway construction,it is necessary to accurately calculate its electricity load and select the most appropriate temporary electricity equipment to ensure overall electricity safety.
