Description

The invention relates to protective clothing and allows you to increase the reliability of electrical protection and ease of use. Protective clothing electrical Invention refers to protective clothing, especially designed to prevent and protect people when working on high-voltage electrical installations.

The aim of the invention is to improve the reliability of 'protective clothing for electricians from electric shock and increased convenience in use.

FIG. 1 shows an electrician's protective clothing, front view; in fig. 2 is a section A-A in FIG. one; on fig.Z - section bb in fig. one; in fig. 4 - protective clothing, rear view; in fig. 5 - section bb In FIG. 4; in fig. 6 shows the layout of conductive shunts channels; in fig. 7 2

The fitter is made in the form of a jumpsuit, contains conductive pads in the knees, buttocks, elbow, groin areas, hand and foot protection, grounding, conductive shunts and alarm systems. Conductive pads c. chest, back, shoulder areas are made in one piece as a coquette with a single sleeve, hand and foot protection are made in one piece with a jumpsuit, conductive shunts are made in the form of two parallel butt-shaped conductors; - with her part of the trousers of the suit and connected with shunts. 7 il.

conductive spring loaded plate to protect the feet.

Protective clothing electrician is a jumpsuit of mesh material. On the front and rear halves of the overalls are conductive pads 1, made in the form of a one-piece yoke with a sleeve of carbon fabric, conductive pads 2 in the knees and 3 buttocks, lining 4 of the inguinal region, conductive pads 5 of carbon material located vertically along the entire length of the overalls from the bottom of the leg to the shoulder pad and along the front and elbow crease of the sleeves, as well as horizontally in the lumbar region and along

setting up the bottom edge of the current the lining 1 front and rear.

Thermal-insulating gaskets 6 (FIG. 2.3) are laid in the areas of the conductive plates 1-5 on the C-side of the lanyard; hand protection means 7 are made in one piece with the sleeve of the overalls; the handheld area of the hand protection is protected by conductive plates 8, under which thermal insulation pads are laid

. Current draining occurs on the continuous 4-channel system of easy-.15 valuable shunt-conductors. Channel layout is as follows: 1st channel

10 begins and ends at stepping seams, runs along the front left or right part of the overalls to the shoulder lining ", then along the front bend of the left or right sleeve, along the bottom (back part) of the sleeves, along the elbow bend of the sleeves and parallel to the shoulder cover plate; 2nd 25

channel 11 also begins at the step seams, and ends at the side seams, it passes along the front of the overalls, turns along the shoulder pad

to the front fold of the sleeves, along the bottom 30 (at the palmar part) of the sleeves, then goes along the ulnar fold of the sleeve, along the back line of the shoulder pad, turns and runs along the entire length of the back to the bottom of the side seams 35

The 3rd channel 12 begins and ends at the side seams of the overalls, it first passes along the side seam, then is horizontal

in the lumbar part of the jumpsuit and 40

runs along the other side seam;

Channel 4 13 begins and ends also at the side seams * It runs along the side seams, then vertically ₍ right back, to the shoulder pad), ¹ 45 ki, horizontally along the back shoulder pad, and then vertically along the side seam.

Each channel carries shunts 14, consisting of two conductors (figure 2).

Thus, when the exit shunts ·

14 a bundle forms at the side seam

 from 6 conductors, at a step seam from 4 conductors. The output beam shun- $$ 14 are connected with the means 15 of the protection of the legs, forming a closed loop of the entire conductive system. Means

15 leg protection consists of a metal plate 16. and metal springs 1 7.

The proposed device works as follows.

If the electrician touches the electrical installation, then the current will flow through the conductive plates 1-5 through the system of shunt-wires 14, consisting of four channels 10-13, and through the means 15 of the leg protection, bypassing the vital organs of the person.

In the proposed protective clothing electrician due to the fact that additional conductive plates of fabric with carbon filaments are also installed in the groin area of the coveralls made of mesh fabric, as well as due to the introduction of conductive pads and a single system of shunts connected to The availability of hand protection tools, which are made in one piece with the sleeve of the overalls, significantly increases the reliability of the electrical protection of workers and the convenience of using protective clothing. At the same time, places of possible contact with live parts are also protected, as a result of which the fabric does not ignite, which withstands the arcing that occurs during a short circuit on an AC contact network of up to 27.5 kV. In addition, protected electrician's clothing increases its electrical protection when working in electrical installations .
