Power transmission line tower grounding device

Abstract

The invention belongs to the electric power system technical field and relates to a power transmission line tower grounding device, in particular to a four-way type power transmission line tower grounding device. According to the power transmission line tower grounding device, connection units are in end-to-end connection with one another through annular grounding bodies so as to from a square; the four connection units are respectively provided with an actinoid grounding body; at least two connection units which are arranged diagonally are provided with grounding downleads; materials for making the connection units are all subjected to hot dip galvanizing anti-corrosion treatment, and therefore, the service life of the grounding device can be prolonged, and the effective sectional area of the grounding body can be increased, and contact resistance can be correspondingly reduced, and lightning protection and current release efficiency can be improved. The power transmission line tower grounding device of the invention has the advantages of simple structure, simple on-site operation and high universality. The power transmission line tower grounding device can satisfy requirements for power transmission line tower grounding device transformation and new line building construction and is applicable to transformation of grounding devices for any form of transmission line towers and construction.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a grounding device for a pole and tower of a transmission line, in particular to a four-way grounding device for a pole and tower of a transmission line. Background technique [0002] At present, the grounding device of the transmission line tower includes a grounding body and a grounding downconductor. The grounding body, also called the grounding electrode, refers to a metal conductor buried in the ground and directly in contact with the soil to discharge current to the earth. The grounding down conductor is a wire used to connect the lightning conductor and the grounding body. Its function is to conduct the lightning current on the lightning conductor and flow into the ground through the grounding body. It is an important part of the transmission line to avoid lightning tripping. Therefore, the grounding device must Reliable and effective, in order to reduce th...
