    Abstract：The store buildings’requirements for power supply reliability vary significantly with the operating business，management mode and grade；the store load classification is proposed by analyzing the business and management mode in combination with several specifications；instead of the construction area，the store grade and business practice are the primary factors in evaluating the influences of various loads on the operation；and choices for important load switching positions and corresponding applicable equipment types are given in the further discussion on the power supply plan of important load in combination with the power supply plan for spacious business hall and business hall with stores arranged in row.

  摘 要：商店建筑因其经营业态、管理模式及档次不同，对供电可靠性的要求有很大区别；通过对商店业态及其管理模式的分析，结合几部规范的规定提出商店负荷分级的建议；商店建筑面积并不是主要因素，重点应考虑商店的档次和经营方式，主要是各类负荷对建筑或商业运营的影响程度；进一步讨论重要负荷的供电方案，结合大空间营业厅和连续排列商铺营业厅的配电方案，给出重要负荷切换位置的几种方式，并分析各方案适用的设备类型。

  关键词：商店建筑；负荷分级；重要负荷；供电方案；电源切换；负荷类别；N - 1原则；备用电源
