Problems solved by technology

However, the reality is that during the maintenance work of the lower line, the position of the operator changes dynamically. If you don’t pay attention, the dynamic safety distance from the upper line may be insufficient, which poses a major safety hazard.

Embodiment Construction

[0038] For ease of understanding, combined here Figure 1-6 , the concrete structure and working mode of the present invention are further described as follows:

[0039] The specific structure of the upper floor anti-shock device used in the present invention is as follows: Figure 1-6 As shown, its main body includes a fixed hoop 10 , a support rod 20 and a support surface 30 arranged sequentially from bottom to top. exist Figure 1-4 and Figure 5-6 In the two groups of embodiments shown, the fixed hoops 10 are all in the shape of a "C" hoop, and the support rods 20 can also purchase telescopic rod structures on the market; the difference between the two groups of embodiments lies in the difference in the number of support rods 20 and the Differences in the configuration of the support surface 30 . in:

[0040] At once Figure 1-4 In the illustrated embodiment, the supporting surface 30 is formed by two hinged rods 32 together with a protective cloth 33 . Protective c...

Abstract

The invention belongs to the technical field of electric shock protection, and particularly relates to an upper-layer electric shock prevention method for lines erected on the same tower. The upper-layer anti-electric shock device comprises a fixing hoop or a fixing strap, the bottom end of a supporting rod is fixed to the fixing hoop or the fixing strap, and the top end of the supporting rod extends upwards and is fixedly connected with a supporting face. The supporting face is in a horizontal protection face shape, and the inner end, relatively close to the electric pole, of the supporting face forms a fixed end relative to the supporting rod. When the anti-electric shock device is used, the fixing hoop or the fixing strap of the upper anti-electric shock device is firstly fixed on an electric pole body, and then the supporting rod is stretched to a position 0.7 m away from an upper line, so that a safety distance 0.7 m exists between a supporting surface and the upper line. According to the invention, the dynamic operation condition of the maintenance operation of the power system can be conveniently satisfied without carrying out power failure operation on the upper-layer lineof the same-pole erected line, and the safety of the maintenance operation of the power system can also be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of electric shock protection, and in particular relates to an electric shock prevention method for an upper layer of a line erected on the same pole. Background technique [0002] Lines are erected on the same pole, that is, two or more lines are erected on the same pole. In the maintenance work of the power system, when the lines erected on the same pole are often energized on the upper 10kV line, the maintenance work of the lower 0.4kV line is carried out simultaneously. Under normal circumstances, there is a sufficient maintenance safety distance between the cross arm of the upper line and the cross arm of the lower line. However, the reality is that during the maintenance work of the lower line, the position of the operator changes dynamically. If one is not careful, the dynamic safety distance from the upper line may be insufficient, which poses a major safety hazard. Contents of the invention [00...
