Description

The invention relates to personal protective equipment against exposure to high-frequency electromagnetic fields and is an improvement to the invention in the art. St. Nfe 753423.

The purpose of the invention is to increase the effectiveness of human protection by eliminating the effect of heating protective clothing in high-frequency electromagnetic fields.

Figure 1 schematically shows protective clothing, front view; figure 2 - the same, rear view.

Protective clothing contains a jacket 1 with a hood 2, dungarees 3, gloves or mittens 4. All of the listed elements of protective clothing are made of electrically conductive fabric. The protective clothing also contains a face shield 5 made of electrically conductive fiber in the form of a sparse mesh and boots or boots 6 on an electrically conductive sole. All elements of protective clothing are electrically interconnected, for which connecting terminals are provided.

leads and jumpers 7. Contact leads are made using a push-button connector, and jumpers are made of electrically conductive fabric. Jacket 1 and semi-overalls 3 have inserts FROM an insulating fabric with ventilation openings. On the seamy side of the jacket, a gasket of insulating material is sewn. On the upper part of the hood, on the back, on the outer sides of the sleeves and gloves, on the floors of the jacket, on the trousers, flexible conductors 8 are attached to the front and back, which protrude above the clothes in the form of pins located 2-3 mm apart from friend The ratio of the height of the pins to the distance between them is 1.3-1.8. The flexible conductors are made of copper wire with a diameter of 0.1-0.3 mm and woven into the electrically conductive fabric of clothing.

When the pins are located in a row at a distance less than 2 mm (more frequent arrangement), the efficiency of their secondary radiation is low due to the mutual overlap of their electric fields. With

more rarely than 3 mm, the location of the pins also reduces the effect of secondary radiation, as the number of secondary emitters (pins) per unit decreases. The ratio of the height of the pins to the distance between them in the range of 1.3-1.8 is also selected from the observation of the occurrence of overlapping of their electric fields.

When placed in a high-frequency anti-electromagnetic field, a person in protective clothing is not exposed to the negative effect of this field, since electrically conductive protective clothing is a partial shield for high-frequency electromagnetic waves. A part of electromagnetic waves, not reflected by protective clothing, induces a voltage on an electrically conductive fabric of clothing. Since the conductive pins are secondary radiation

-

With all the bodies, then the entire energy of the voltage induced on the electrically conductive fabric is spent on secondary radiation, so the protective clothing is not heated.
