一。电子设备中的屏蔽与接地处理电磁干扰是电子设备或通讯设备中最主要的干扰形式。电磁兼容性就是指电子设备在电磁场环境中的适应能力,所以电子设备的抗干扰设计就是使设计的电子设备对在同一环境中工作的其他电子设备,既不产生干扰也不受到电磁干扰的影响。运行中的各类电气、电子设备都能产生各种电磁能量,产生干扰。许多设备既可能产生和发射电磁干扰,也可能受环境电磁干扰的影响。
one. Shielding and grounding in electronic equipment Electromagnetic interference is the most important form of interference in electronic or communications equipment. Electromagnetic compatibility refers to the ability of electronic equipment to adapt to the electromagnetic field environment, so the anti-interference design of the electronic equipment is to make the designed electronic equipment to other electronic equipment working in the same environment, neither generating interference nor being affected by electromagnetic interference . All kinds of electrical and electronic equipment in operation can generate various kinds of electromagnetic energy and cause interference. Many devices can generate and emit electromagnetic interference as well as electromagnetic interference from the environment.
