Novel grounding reinforcement device and construction method thereof

Abstract

The invention discloses a novel grounding reinforcement device which comprises an upper pressing plate, a lower pressing plate, a middle pressing plate and a detachable fastener, wherein the upper pressing plate is made of an insulating material; a first notch raised in the outside direction is formed in the inner side of the upper pressing plate; two ends of the first notch respectively penetrate through the edge of the upper pressing plate; the lower pressing plate is made of an insulating material; the inner side face of the lower pressing plate is opposite to the inner side face of the upper pressing plate; a second notch raised in the outside direction is formed in the inner side of the lower pressing plate; two ends of the second notch respectively penetrate through the edge of the lower pressing plate; the middle pressing plate is made of a conductive material and is arranged between the inner side faces of the upper pressing plate and the lower pressing plate; a first clamping space is formed between the inner side face of the upper pressing plate and a corresponding side of the middle pressing plate; a second clamping space is formed between the inner side face of the lower pressing plate and the corresponding side of the middle pressing plate; the upper pressing plate, the middle pressing plate and the lower pressing plate are connected in a fastened manner by virtue of the detachable fastener. The novel grounding reinforcement device has the advantages that the reliability and the service life of the device are greatly improved when being compared with those of the conventional device, and the subsequent grounding maintenance quantity of the equipment can be reduced.

Description

technical field [0001] The invention relates to a novel grounding reinforcement device and a construction method thereof. Background technique [0002] The main function of the grounding device is to quickly diffuse and conduct lightning current in the ground to maintain a certain level of lightning resistance of the line. When lightning strikes a tower, part of the lightning current flows to the adjacent tower through the lightning protection wire, and the other part flows into the ground through the tower. The grounding resistance of the tower has a transient resistance characteristic, which is generally characterized by the impact grounding resistance. The good grounding of the line tower can effectively improve the lightning resistance level of the line and reduce the probability of counterattack. [0003] However, the long running time and the quality and process problems in the manufacture and installation of concrete poles lead to defects in the concrete grounding do...

AI Technical Summary

Problems solved by technology

[0004] The traditional pole grounding device in the prior art has the following disadvantages: 1. The anti-corrosion measures are not perfect, and the corrosion is very serious due to long-term operation; 2. The connection point has virtual welding; 3. The contact area between the grounding body and the grounding down conductor Small; 4. Many connection parts are only maintained in the form of rust
