Grounding device based on installation and construction of transmission lines in power transmission and transformation projects

Abstract

The invention provides a grounding device based on the installation and construction of transmission lines in power transmission and transformation projects, including a tower body; horizontal connecting plates are respectively connected to the two sides of the top of the tower body, and the lower side of the horizontal connecting plate is provided with a horizontal bracing plate. Two sets of vertical plates are connected in the middle of the top of the tower body, and vertical insulating sleeves are interspersed in the middle of the inner side of the tower body; the lightning protection part is installed in the middle of the top of the tower body; the winding mechanism is installed on the cross support plate ; The protective piece is set on the bottom outer end of the tower body. In thunderstorms, use the pull rope to pull the upper shield, make the upper shield slide on the guide rod to both sides, and leak the lightning rod so that the lightning rod can play the role of lightning protection. Under the action of the spring, it shakes slightly to avoid the phenomenon that the lightning rod is easily broken due to its fixed connection. By setting the protective part, it plays the role of protecting the bottom of the tower body.

Description

technical field [0001] The invention belongs to the technical field of power transmission engineering construction, and more specifically relates to a grounding device based on the installation and construction of transmission lines in power transmission and transformation projects. Background technique [0002] The main causes of accidents on transmission lines can be attributed to bird damage, lightning strikes and external damage. Among them, the damage caused by lightning strikes is often more serious and causes many safety problems; Points: One is lightning protection, using corresponding devices to avoid damage caused by lightning strikes; the other is grounding, using static grounding to avoid adverse effects of static electricity on the power system, so it is necessary to carry out lightning protection and grounding protection for transmission towers. [0003] For example, the patent with application number CN201910462667.6 discloses a lightning protection and ground...

AI Technical Summary

Problems solved by technology

[0004] Based on the above, in the traditional transmission tower structure, the lightning protection structure is fixedly connected to the top of the tower body. In strong wind or thunderstorm weather, it is easy to break the lightning protection structure and affect the overall lightning protection effect of the tower body. Secondly, the bottom of the tower body lacks a protective structure. It is easy to cause danger when passers-by climb or touch
