Description
Technical Field
The utility model relates to an earthing device, concretely relates to transmission line's theftproof earthing device.
Background
The power transmission line is often built in plain, hilly and mountain mountainous areas and open fields, is exposed in the atmospheric environment, is easy to be struck by lightning, and the lightning stroke line can cause faults such as power transmission line tripping. The purpose of installing the grounding device on the power transmission line is to enable lightning current acting on the conducting wire and the ground wire to be discharged to the ground along the grounding body as soon as possible, so that the damage of line facilities such as the conducting wire, the insulator and the like caused by lightning overvoltage is avoided. But because transmission line resident law consciousness along the line is thin, easily receives the benefit to order about to and current earthing device withdrawal resistance is not enough, cause the stolen condition of earthing device serious, cause very big influence for the operation safety of circuit, maintainer will frequently overhaul the change simultaneously, increased intensity of labour and working costs.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome prior art not enough, provide a simple structure, fixed firm, the strong transmission line's of withdrawal resistance theftproof earthing device.
The utility model provides a technical scheme that its technical problem adopted is, a transmission line closed type theftproof earthing device, including the horizontal grounding body, the horizontal grounding body is "mouthful" style of calligraphy closed frame, is equipped with the theftproof angle steel on its outer frame, the theftproof angle steel is the nail type, the extreme point and the midpoint department of horizontal grounding body frame are equipped with the theftproof angle steel for the anchor horizontal grounding body.
Furthermore, the upper portion of theftproof angle steel is equipped with the barb, and the lower extreme is equipped with the closed angle.
Furthermore, the horizontal grounding body is galvanized round steel and is laid on the periphery of the foundation of the power transmission line tower.
Utilize the utility model discloses transmission line iron tower earthing device of construction has good theftproof performance, effectively reduces transmission line operation maintenance's the degree of difficulty and cost, improves the fail safe nature of transmission line operation.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a schematic structural view of the anti-theft angle iron in the embodiment shown in fig. 1.
In the figure: 1. the anti-theft angle iron comprises a horizontal grounding body, 2 parts of anti-theft angle steel, 2-1 parts of barbs and 2-2 parts of sharp corners.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to the attached drawings 1-2, the anti-theft grounding structure comprises a horizontal grounding body 1, wherein anti-theft angle steel 2 is arranged on an outer frame of the horizontal grounding body 1, the horizontal grounding body 1 is a closed frame shaped like a Chinese character 'kou', and the anti-theft angle steel 2 is in a nail shape.
The horizontal grounding body 1 adopts phi 12 galvanized round steel, is laid on the periphery of the iron tower foundation of the power transmission line and is in a square closed frame. A plurality of anti-theft angle steels 2 are arranged at the outer frame end points and the evenly spaced points of the square closed frame.
The anti-theft angle steel 2 is L40x5 angle steel, the length is 400mm, the barb 2-1 is arranged on the upper portion, the size of the barb 2-1 is matched with that of the horizontal grounding body 1 and used for anchoring the horizontal grounding body 1 to ensure that the horizontal grounding body 1 cannot be easily pulled out, and the sharp corner 2-2 is arranged on the lower end to facilitate hammering into soil.
According to the embodiment, the horizontal grounding body 1 is firmly embedded around the iron tower foundation of the power transmission line by utilizing the uniformly distributed anti-theft angle steels 2, the barbs 2-1 are arranged at the upper ends of the anti-theft angle steels 2, and the anti-theft angle steels are difficult to pull out without special tools, so that the anti-theft function is realized.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are still within the scope of the present invention, provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
