低压配电系统接地制式研究

Research of the Low-voltage Distribution Systems' Grounding Type

本文从防雷工程设计施工实践出发,按照国内外相关防雷技术标准中的规定,对IT、TT、TN这三种接地制式进行判别,有利于SPD在低压配电系统中的安装。

According to the domestic and foreign relevant technical standards of lightning protection regulations,we this paper distinquishs the IT,TT,and TN grounding types from the practice of lightning protection engineering design and construction.It is available for SPD’s installation in low voltage distribution system.
