摘　　要：论述负荷等级的划分原则、划分标准及国家规范要求的一、二级负荷供电要求。就目前电气设计过程中对于消防和非消防一、二级负荷供电的常规做法,特别是配电线路最末一级配电箱处的做法进行系统分析。从经济和技术两个方面比较,结合相关国家规范和设计手册,系统阐述其在配电线路最末一级配电箱处设置自动切换装置的必要条件,提出合理化的设置建议。This paper discusses the division principle and division standard of load grade and the power supply requirements of class I and class II loads required by the national specifications, and systematically analyzes the conventional methods of power supply for fire-fighting and non fire-fighting class Ⅰ and class Ⅱ loads in the current electrical design process, especially the methods at the last level distribution box of the distribution line, and compares them from the economic and technical aspects.In combination with the relevant national specifications and design manuals, it systematically expounds the non fire-fighting class I The second level load needs to set the necessary conditions of automatic switching device at the last level distribution box of the distribution line, and put forward reasonable setting suggestions.
