Pole and tower grounding device

Abstract

The invention provides a pole and tower grounding device. The pole and tower grounding device comprises first connecting beams, second connecting beams, a grounding plate and a grounding fringing ball, wherein multiple first connecting beams are arranged, the first connecting beams are connected end to end and define a closed loop, the second connecting beams are arranged at joints of the first connecting beams, one end of each second connecting beam is located inside the closed loop, the other end of each second connecting beam is located outside the closed loop, the grounding plate is arranged at one end, located in the closed loop, of each second connecting beam, the grounding fringing ball is arranged at one end, located outside the closed loop, of each second connecting beam, and an acupuncture is arranged on each second connecting beam. The acupuncture is arranged on each second connecting beam, shunt acupunctures can be increased, current can be beneficially and rapidly guided into soil, and current fringing capability of the grounding device also can be improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission line construction, and in particular relates to a pole tower grounding device. Background technique [0002] With the continuous increase of power transmission capacity of the power grid, when the transmission line fails, the magnitude of the short-circuit current is also increasing. Insulator short to ground fault. [0003] 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 transmi...

AI Technical Summary

Problems solved by technology

[0005] 1. The structure of the grounding equipment is simple, the form is solidified, and the lightning protection effect is poor;

[0006] 2. The contact area between the grounding electrode and the soil of the grounding equipment is small, which cannot meet the requirements of large current discharge to the ground;

[0007] 3. The grounding device cannot collect the leakage generated when lightning strikes, the efficiency of lightning protection and leakage is low, and there are certain safety hazards
