Grounding device based on power transmission and transformation project power transmission line installation and construction

Abstract

The invention provides a power transmission line installation and construction grounding device based on a power transmission and transformation project. The device comprises a tower body, wherein transverse connecting plates are connected to two side frames of the top end of the tower body respectively, transverse supporting plates are arranged on the lower sides of the transverse connecting plates, two sets of vertical plates are further connected to the middle of the top of the tower body, and a vertical insulating sleeve is inserted into the middle of the inner side of the tower body in a penetrating mode; a lightning protection part which is mounted in the middle of the top of the tower body; a winding mechanism which is mounted on the transverse supporting plate; and a protection piece which is arranged at the outer end of the bottom side of the tower body in a sleeving manner. In thunderstorm days, the upper protective cover is pulled through the pull rope, so that the upper protective cover slides towards the two sides on the guide rod, the lightning rod is exposed, the lightning rod can play a lightning protection role, and in case of strong wind, the lightning rod shakes in a small range under the action of the lower protective cover and the supporting spring, and the phenomenon that the lightning rod is easily broken due to fixed connection is avoided; by arranging the protection piece, the effect of protecting the bottom of the tower body is achieved.

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
