The role of electromagnetic shielding room in our lives continues to increase, meeting the needs of production engineering. It can be divided into direct attach type and copper mesh type. The steel plate welded structure of the electromagnetic shielding room is welded by 2～3mm cold-rolled steel plates and the keel frame. It has high shielding efficiency and adapts to various specifications and sizes. It is the main form of the electromagnetic shielding room. It is suitable for projects with small area and general requirements for shielding effectiveness. Why is the electromagnetic shielding room so affirmed? We have summed up its use value.
The electromagnetic shielding room can prevent the harmful electromagnetic energy or harmful radiation generated by the equipment from leaking. Electronic equipment radiates harmful electromagnetic waves to the environment during operation, such as high-power electronic emission equipment, medical nuclear magnetic resonance rooms, CT rooms, etc. Therefore, electromagnetic shielding measures must be installed.
The electromagnetic shielding room can be used to steal secrets. Generally, there are laser resonance and loudspeaker resonance. The laser resonance type mainly measures the vibration of the glass windows of the conference room to restore the voice information of the indoor speaker; to prevent this information from spreading in the air, special technical measures must be taken to protect and suppress the leakage of electromagnetic radiation, and technical measures to solve this leakage There are: interference technology and shielding technology.
The electromagnetic shielding room can also increase the influence of electromagnetic waves on electronic equipment, reduce the stability of the equipment, and greatly increase the failure rate, which directly affects the normal operation of the electronic system. Therefore, the electromagnetic shielding room will play a very important role in the protection of important electronic equipment such as electronic information systems, command systems and weapon equipment systems.
The installation process of the electromagnetic shielding room mainly includes the construction of keel frame, the welding of steel plate modules, the installation of protective doors, filters, waveguide windows, adapter plates, etc., the connection of waveguide windows and air-conditioning vents, self-checking of protection efficiency, indoor electrical laying, interior decoration, etc. step. In order to prevent minor installation problems, it is necessary to do protection work.
