信号(直流)接地方案

A Project of DC signal Earthing

本文从电磁干扰到电磁兼容等方面,阐述了信号(直流)接地在计算机系统中的重要性,介绍了多点接地、单点接地在电磁兼容、防雷要求上存在的差异。根据综合接地示意图,并结合自己多年工作实际提出了一种计算机系统信号(直流)接地方案。

In this paper we explained the importance of DC signal earthing in compute r system in the aspects of electromagnetic inte rference,compatibility and so on.W e also introduced the differ-ence between multi -point and single point earthing in the aspects of electromagnetic compatibility and the requirement of lightning pro tection.At last,we provide a project of DC signal earthing in computer system according to the int egrated sketch map and our many years' experience.
