多电源TN系统的N线在哪里一点接地

摘要

In combination with actual engineering projects, the Code of Acceptance of Construction Quality of Electrical Installation in Building ( GB 50303 - 2002) and Low-voltage Electrical Installations— Part 1: Fundamental Principles, Assessment of General Characteristics, Definitions (GB / T 16895. 1- 2008 / IEC 60364 - 1: 2005) are compared for their differences in provisions on multiple power TN system earthing as well as their roles in preventing the occurrence of stray current and withstanding the stray electromagnetic interference.%　　从工程实际出发，比较 GB 50303-2002《建筑电气工程施工质量验收规范》及 GB / T 16895.1-2008/ IEC 60364-1：2005《低压电气装置第1部分：基本原则、一般特性评估和定义》对多电源 TN系统接地规定的不同点，以及二者防止杂散电流产生、抗杂散电磁干扰的功能。
