电子信息系统接地抗干扰技术之探讨

Discussing Technology for Grounding and Restrain Disturbance of Electron and Information System

电磁干扰作为能降低电子设备有效性能发挥的电磁能量,已成为电子信息系统安全稳定工作的突出障碍。而恰当良好的接地是工程实际中抑制干扰,使设备或系统可靠工作的重要方法。针对电子信息系统不同接地方式抑制电磁干扰性能的不同,讨论了几种接地方式的优缺点及适用范围,对于电磁干扰抑制在电子信息系统中的实际应用具有一定的指导意义。

Electromagnetic interference, as an energy of electromagnetism that may degrade the performance of electron equipment ,has been the outstanding obstacle of the electron and information system＇s working in a stable and safe state,and the proper grounding is an important method which can restrain disturbance in the practical engineering and to make the equipment or system working reliably. While different grounding methods of electron and information system, different suppress the performance of electromagnetic interference, this paper brings about several grounding methods and analyzes strongnees, weakness and available scope, which has instructional significance for practical application of electromagnetism interference suppression in electron and information system.
