Embodiment 1

[0024] like figure 1 As shown, an anti-static protection board for electric power maintenance includes an outer board body 101 and an inner board body 102. The upper and lower ends of the outer board body 101 are provided with bent parts 103. A chute 104 is provided on the upper and lower end surfaces of the laminate body 102, and one end of the bent portion 103 is snapped into the chute 104, and a blind hole 105 is provided on one end surface of the chute 104, and The upper end surface of the bending portion 103 is provided with a threaded hole, and a bolt 106 is arranged in the threaded hole, and the bolt passes through the threaded hole and is embedded in the blind hole 105. A rubber layer 106 is provided on the outer end surface of the bending portion 103, and the rubber layer is bonded to the bending portion 103 by a fireproof adhesive, and the rubber layer 106 is rubber mixed with white carbon It is made of black and fire-proof adhesive, and the surface of the outer pla...

Embodiment 2

[0027] In order to improve the safety performance, on the basis of Embodiment 1, in this embodiment, preferably, both the outer layer body 101 and the inner layer body 102 are covered with insulating rubber.

[0028] In order to facilitate grasping, in this embodiment, preferably, a handrail 107 is provided on the side wall of the outer layer body 101, an insulating layer 108 is provided on the said handrail 107, and an insulating layer 108 is provided on the said handrail 107. The grounding device 109 of the insulating layer 108 is provided on it. By setting the insulating layer, it is possible to avoid electric shock when holding the handrail.

[0029] In order to avoid denaturation and aging of the insulating layer under the action of light, in this embodiment, preferably, the surface of the insulating layer 108 is coated with cured titanium dioxide colloid.

[0030] In order to improve the fireproof performance, in this embodiment, preferably, the cured titanium dioxide c...

Abstract

The invention discloses an antistatic protection plate for electric power overhauling. The antistatic protection plate comprises an outer-layer plate body and an inner-layer plate body. End faces of upper and lower ends of the outer-layer plate body are provided with bent parts. Slide grooves are arranged in upper and lower end faces of the inner-layer plate body. One end of each of the bent parts is clamped in the corresponding slide groove. A blind hole is arranged in the end face of one end of each of the slide grooves. A threaded hole is arranged in the end face of the upper end of each of the bent parts. A bolt is arranged in each of the threaded holes, penetrates through the corresponding threaded hole and then is embedded in the corresponding blind hole. A rubber layer is arranged on the outer side end face of each of the bent parts. Each of the rubber layers is made of rubber mixed white carbon black and fireproof binder. The surface of the outer-layer plate body and the surface of the inner-layer plate body are covered by antistatic fiber cloth. The antistatic fiber cloth is made of woven cotton fiber winding antistatic wires. According to the invention, by using the relatively-sliding two layers of plate bodies, and arranging the rubber layers and antistatic limit cloth, safety of the whole structure is improved.

Description

technical field [0001] The invention relates to an antistatic protection board for electric power maintenance. Background technique [0002] At the power maintenance site, when a short-circuited high-voltage line breaks and falls on the ground, a ground potential area will be generated on the ground. When workers enter the ground potential area, step voltage is likely to exist, causing electric shock accidents. Contents of the invention [0003] The purpose of the present invention is to provide an anti-static protection board for electric power maintenance, which can improve the problems existing in the prior art. Two boards are used to isolate the ground potential area, and two-layer boards that can slide relatively are used, and by setting The rubber layer and anti-static limit cloth improve the safety of the overall structure. [0004] The present invention is realized through the following technical solutions: [0005] An anti-static protection board for power maint...
