电子信息系统中接地方法的分析

为了提高电子信息系统抑制电磁干扰的能力,采取恰当良好的接地方法是工程实际中的重要措施之一。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,根据工程中电子信息系统的特点和电子设备的具体情况,采取了相应的接地方法,有效地消除了各电路电流经公共地线阻抗时产生的共阻抗耦合干扰及地环路电流与其它电路产生的磁耦合干扰,避免了电路受磁场和地电位差的影响,抑制了电子信息系统的直流接地干扰,保证了电子信息系统正常安全的工作。

Discussing and study for grounding method of electron and information system

In order to restrain disturbance in the practical engineering and to make the equipment or system working reliably,the proper grounding is being an important method.While different grounding methods of electron and information system,different suppress the performance of elect romagnetic interference,the direct current grounding methods for restrain disturbance of the electron and information system were preserted and discussed in this paper.
