摘　　要：临时用电几乎是每个施工现场必有的内容,其普遍性及重要性不言而喻。临电设备布置的合理性不但决定着成本投入的多少,更决定着施工安全性、便捷性。本文以作者参与的某码头辅助建筑物工程为例,分别从负荷计算、配电箱布置、电缆选择及敷设方式等方面详细阐述设计思路。在符合规范的前提下,形成一种相对最优的临时用电设计方案,并提出施工现场经常出现的理解误区,为相关工程提供思路与经验。其中防雷接地、安全防护等内容不在本文探讨范围内。Temporary electrical supply is a necessary sub-item in almost every project,thus its universality and importance are self-evident.Appropriate layout of temporary electric supply units not only reduces the construction cost,but also leads to the safety and convenience in constructing.Based on the auxiliary building project of a terminal,the design ideas were analyzed in detail from the aspects of load calculation,the layout of distribution boxes,the selection of cable specifications and laying methods.On the premise that the specifications were complied with,a relatively optimal design plan of temporary electrical supply was proposed,and the misconceptions about the construction were pointed out.The above design ideas and experience are beneficial to the related projects.Lightning protection,grounding and safety are not covered in this article.
