The shielded room is a closed room composed of metal plates or metal meshes. The radar microwave radiation leakage value of the shielded computer room is in full compliance with the restraint norms, and is higher than the national mass irradiance restraint norms, which can play a useful role in protecting the human body working and watching in its vicinity. So what is the design principle of the shielded room? The following is introduced by the staff of the manufacturer:
1. The design principle of the shielded room is mainly: during the transmission of the electric wave, the alternating magnetic field and electric field are replaced, and the electric field is used when it tries to pass through the shielding shell made of ferromagnetic material with excellent grounding function. The energy will be attenuated by having a grounded conductor, and the magnetic field energy will be lost by generating eddy currents in the material passing through the magnetic field. Therefore, its strength will be shielded by greater attenuation and play a role in shielding and blocking electromagnetic waves.
2. Shielding is to use a metal plate (metal mesh) to make a hexahedron to confine the electromagnetic wave within a certain space so that the energy of the field is greatly attenuated from one side to the other. The shielding room is to use its shielding principle to make a hexahedral room with metal materials. Due to the absorption loss of the metal plate (net) to the incident electromagnetic wave, the interface reflection loss and the reflection loss within the plate, the energy of the electromagnetic wave is greatly reduced, and Make the shielding room have a shielding effect. Because there are usually people and equipment working in the shielded room, while the shielding room is sealed on six sides, there must be a shielded door for personnel and equipment to enter and exit, good ventilation, indoor power supply, signal entry and exit, and necessary indoor Renovate to ensure that the shielded room can work properly.
3. The function of the shielded room is mainly derived from whether there is a high-function shielded door. The shielded door is crimped with the knife on the door panel through the application of the reed, thereby increasing the number of leaking electric waves and reaching the leak-proof Claim. The size of the air volume selects the area and unit of the ventilation waveguide, and the hexagonal honeycomb-shaped wind-permeable cloud guide window is placed in the shielding shell. The permeable cloud guide window is formed by vacuum lead welding in a hexagonal honeycomb-shaped cut-off wave drain pipe in accordance with microwave practice and strict technology.
