Corrosion-free conductive resistance-reducing material and its maintenance-free grounding device

Abstract

The invention discloses a non-corrosive electricity conduction and resistance reduction material and a maintenance-free grounding device comprising the non-corrosive electricity conduction and resistance reduction material. The non-corrosive electricity conduction and resistance reduction material is mainly composed of raw material asphalt, graphite or / and calcined coke and cement. The maintenance-free grounding device comprising the non-corrosive electricity conduction and resistance reduction material comprises 4-8 grounding electrodes which are horizontally arranged or vertically buried under the ground. The grounding electrodes are mutually connected through metal grounding down leads and horizontal metal grounding bodies to form a metal grounding looped network. Each grounding electrode comprises a metal grounding body and a non-corrosive electricity conduction and resistance reduction material layer, wherein the thickness of the non-corrosive electricity conduction and resistance reduction material layer is 30-45 millimeters, and the use amount of the non-corrosive electricity conduction and resistance reduction material wrapped around the outer surface of every one-meter long portion of the metal grounding body is 6-8 kilograms. The metal grounding down leads, the horizontal metal grounding bodies and the metal grounding bodies are connected in a welded mode. By means of the technical scheme of the non-corrosive electricity conduction and resistance reduction material and the maintenance-free grounding device comprising the non-corrosive electricity conduction and resistance reduction material, the corrosion problem of an existing grounding device can be solved effectively.

Description

Technical field [0001] The present invention involves a conductive material and grounding device, which is the field of conductive material technology, especially involving a non -corrosive conductive resistance and anti -maintenance materials. Background technique [0002] The corrosion of steel is a natural phenomenon, a technical problem that is difficult to overcome, and a major topic worthy of research.The grounding device is buried in the underground operation, and the operating conditions are harsh. In the areas of easily corrosive areas, the grounding device will be corroded by the corrosion of the ground. It can only be renovated, which will cause great waste of human and material resources. [0003] There are two ways to conduct electrical conductivity, one is electronic conductivity and the other is ionic conductivity.Ion conductivity is the main conductive method of the earth, and the earth soil is a complex multi -structured structure, including sand, soil, particles...

AI Technical Summary

Problems solved by technology

The grounding device is buried underground for operation, and the operating conditions are harsh. In a corrosion-prone area, the steel grounding body of the grounding device will be corroded within a few years and can only be rebuilt, resulting in a great waste of manpower and material resources.
