摘要
电气设备在其运行过程中发出的有用信号，对其它设备而言可能是无用信号。同时，设备也受到外来无用信号的影响———干扰。在不损失有用信号所包含信息的条件下，有用信号和干扰信号的共存能力称为电磁兼容（ＥＭＣＥｌｅｃｔｒｏ－ｍａｇｎｅｔｉｃＣｏｍｐａｔｉｂｉｌｉｔｙ）。本文拟就电磁干扰的产生及传输、电磁干扰的危害、电磁兼容要求和试验方法标准，以及电气设备的抗干扰设计方法等进行初步分析和探讨。
Electric equipment in operation sedn out useful signals,which may be useless to other equipment.Meanwhile,the equipment also is affected by outer useless signals--disturbance.Under condition that the informations included in the useful signal are not lost,the ability that useful signal and disturbance signal exist together is called as electro-magnetic compatibility(EMC).This paper analyzes and discusses the generation,transmission and harm of electro-magnetic disturbance,the requirement and test standard of the EMC as well as anti-interference design method of electric equipment.
