1屏蔽链路的接地屏蔽链路本身应使用单点接地,即配线架端接地方式。在与计算机网络设备连接后,由于网络设备(包括网卡)都接在PE地上,因此形成了事实上的三点接地。这样,在高频应用时,系统形成了多点接地,它满足了最基本的高频抗干扰要求:能够抑制电场干扰,同时对磁场干扰也具有 1 shielded chain grounding shield The link itself should use a single point of grounding, patch panel end grounding. After connecting with the computer network equipment, as the network equipment (including network card) are connected to the PE ground, thus forming a de facto three-point grounding. In this way, when the high-frequency application, the system formed a multi-point grounding, which meets the most basic high-frequency anti-interference requirements: to suppress electric field interference, but also has a magnetic field interference
