Problems solved by technology

[0003] The middle of the existing graphite ground electrode is stainless steel wire, and the outside of the stainless steel wire is braided with graphite wire. The graphite ground electrode with such a structure has a small graphite ground surface, which cannot withstand the huge current caused by lightning, thus losing the lightning protection effect.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 Shown: a colloidal graphite ground electrode, including a graphite soft rope 1, is characterized in that: the graphite soft rope 1 is installed in a colloidal graphite block 2, and two ends extend out to be used for connecting the connecting end 3 of the circuit, the described The colloidal graphite block 2 is in an elongated block structure. The colloidal graphite block 2 is formed by mixing and solidifying colloidal graphite 4 and water. The graphite soft rope 1 is in a coiled state in the colloidal graphite block 2, so that the voltage uniform delivery,

[0018] A layer of colloidal graphite 4 is evenly coated on the contact portion between the connecting end 3 and the colloidal graphite block 2 for strengthening the graphite soft rope 1 .

[0019] The colloidal graphite block 2 is formed by mixing and solidifying colloidal graphite 4 and o...

Abstract

The invention relates to a high-voltage iron tower grounding device, and particularly to a colloidal graphite grounding electrode. The colloidal graphite grounding electrode comprises a graphite flexible rope and is characterized in that the graphite flexible rope is mounted in a colloidal graphite block; connecting ends for connecting with lines extend out of two ends; the colloidal graphite block has an elongated block-shaped structure; the colloidal graphite block is obtained through mixing colloidal graphite and water and solidifying; and the graphite flexible rope is in a coiled state in the colloidal graphite block so that voltage is uniformly transmitted. The colloidal graphite grounding electrode has advantages of high electric conductivity, high absorption, high plasticity, no soil environment, long service life, high corrosion resistance, simple production, stable grounding resistance, high binding ability with soil, and low contact resistance.

Description

technical field [0001] The invention relates to a grounding device for a high-voltage iron tower, in particular to a graphite grounding electrode. Background technique [0002] The graphite grounding electrode is mainly used to protect the iron tower against lightning and discharge lightning to the earth. [0003] The middle of the existing graphite ground electrode is stainless steel wire, and the outside of the stainless steel wire is braided with graphite wire. The graphite ground electrode with such a structure has a small graphite ground surface and cannot bear the huge current caused by lightning, thus losing the lightning protection effect. Contents of the invention [0004] The purpose of the present invention is to address the above-mentioned shortcomings, to provide a high conductivity, high adsorption, high plasticity, no pollution to the soil, long validity period, corrosion resistance, simple production, stable grounding resistance, strong binding ability with...
