METHOD FOR CONSTRUCTING AN ELECTROMAGNETIC PULSE SHIELDING FACILITIY AT PROTECTION ROOM AND THE ELECTROMAGNETIC PULSE SHIELDING FACILITIY

摘要

The present invention relates to an electromagnetic pulse shielding apparatus and a method of controlling the electromagnetic pulse shielding apparatus in a protection room in which an inner space is formed by a plurality of walls, electronic equipment is provided in the inner space, and manpower for operating the electronic equipment temporarily or permanently stays in the inner space Wherein the wall surface of the wall is surface-treated so as to have a surface roughness higher than a first predetermined roughness; Attaching a metallic first plate to a peripheral portion of a vent hole passing through the first wall of the plurality of walls; Attaching a metallic second plate to the periphery of the waveguide insertion hole passing through the second wall of the plurality of walls; (Zn) -Aluminum (Al) wire is sprayed on the wall surface of the wall through an arc sprayer to form an arc sprayed metal shielding layer on the wall surface of the wall, the first plate and the second plate And the zinc-aluminum wire is also sprayed between the edges of the first plate and the second plate and the wall surface of the wall to continuously form the arc-sprayed metal shielding layer ; A first electromagnetic wave shielding gasket is attached on the first plate so as to surround the air hole and multiple holes are formed to allow ventilation to the inside and outside of the protection room, Attaching a metallic ventilation duct to the first electromagnetic wave shielding gasket; And a second electromagnetic wave shielding gasket is attached on the second plate so as to surround the waveguide insertion hole and a protrusion of a waveguide through which a plurality of electric wires for supplying electric power or electric signals to the electronic equipment are inserted, 2 electromagnetic wave shielding gasket, wherein the electromagnetic wave shielding facility is installed in a protection room including the step of attaching the waveguide so as to be in close contact with the electromagnetic wave shielding gasket.
