Low-frequency electromagnetic shielding chamber

Abstract

The invention discloses a low-frequency electromagnetic shielding chamber. The chamber is formed by welding and sealing a plurality of shielding plates, the interior of the low-frequency electromagnetic shielding chamber is composed of a main machine chamber and an operation chamber. A first electromagnetic shielding door frame is arranged between the host room and the operation room; a first electromagnetic shielding door with a shielding protection function is arranged on the inner side of the first electromagnetic shielding door frame; the first electromagnetic shielding door frame is connected with a magnetic conductive material layer through a riveting hook; a transparent observation window and a control panel are arranged on one side of the first electromagnetic shielding door, a second electromagnetic shielding door with a shielding enhancing function is arranged outside the operation chamber, a waveguide port is formed in the main machine chamber, and a power supply filter anda signal filter are arranged in the operation chamber. The low-frequency electromagnetic shielding chamber is reasonable in structural design, the sealing effect of the main machine chamber is effectively improved, and the electromagnetic shielding effect of the main machine chamber is remarkably enhanced.

Description

technical field [0001] The invention relates to an electromagnetic shielding device, in particular to a low-frequency electromagnetic shielding room. Background technique [0002] The electromagnetic shielding room is generally isolated from external electromagnetic interference. The electromagnetic shielding room is used to simulate the ideal electromagnetic environment to ensure the accuracy of the test results in the measurement and testing of indoor electronic and electrical equipment, and to block the spread of indoor electromagnetic radiation to the outside world, and will strongly The electromagnetic radiation is shielded and isolated to prevent interference with the normal operation of other electronic and electrical equipment or damage the health of the staff, prevent information leakage of electronic information equipment, and ensure information security. [0003] At present, there are two main structures for electromagnetic shielding room: fixed electromagnetic sh...
