摘　　要：施工现场临时用电负荷计算的方法有多种,其计算结果直接决定临时用电的组织与实施以及后期变压器容量和线缆选择。根据现场用电实例,分别选用需要系数法、利用系数法以及常用的临时用电简化方法进行负荷计算,对这三种方法的计算结果和设备选择进行比较分析。结合实际工作,在此基础上,对负荷计算的方法进行了推导和改进,从而为临时用电计算提供了一个新的方法。There are many methods to calculate the temporary electricity load in the construction site ,Which directly determine the organization and implementation of temporary electricity and the selection of the transformer capacity and the cable.According to the temporary electricity examples,the paper use demand coefficient method, utilization coefficient method and the simplified method to calculate the load calculation, and analysis the results of the three methods .Combined with the actual work practice, this paper deduced and improved the method of load calculation, so as to provide a new calculation method for the temporary use of electricity.
