关于民用建筑中低压配电级数的探讨
摘要：文章主要结合JGJ 16-2008《民用建筑电气设计规范》(以下简称《民规》)第7. 1. 4条和GB 50052-2009《供配电系统设计规范》(以下简称《供配电规范》)第4. 0. 6条对低压配电级数的要求，通过对条文的解释以及对民用建筑中典型配电系统案例进行分析，提出民用建筑低压配电系统中配电级数计算方式中的注意事项，同时提出民用建筑中末端设备及其控制箱应视为整体纳入配电级数的计算。
关键词：配电级数 保护级数 电压等级 终端用电设备 重要负荷

Discussion on the Series of Low-voltage Power Distribution in Civil Buildings
Abstract: The article is mainly combined with Article 7. 1. 4 of JGJ 16-2008“Code for Electrical Design of Civil Buildings”( hereinafter referred to as “Civil Rules”) and GB 50052-2009 “Code for Design of Power Supply and Distribution Systems ”( hereinafter referred to as “Code for Power Supply and Distribution”) Article 4. 0. 6 requires the low-voltage power distribution levels. Through the interpretation of its provisions and the analysis of cases of typical power distribution systems in civil buildings,it is proposed that attention should be paid to the calculation method of power distribution levels in low-voltage power distribution systems for civil buildings At the same time,it is proposed that the terminal equipment and its control box in civil buildings should be considered as a whole to be included in the calculation of the distribution level.
Keywords: number of power distribution stages; protection level; voltage level; terminal power equipment; important load;
