Abstract

The invention relates to an anti-lightning, anti-static earth and anti-breakdown earth electrode manufactured by a carbon fiber. The invention relates to an earth electrode that is formed by mechanical weaving of a carbon fiber mixed with expanded natural graphite. According to a construction condition, the earth electrodes can be woven into ones with various shapes like a strip shape, a band shape, a rope shape and a cylinder shape and the like and with random lengths; and stainless steel wires, brass wires, and alloy wires and the like can be added to the earth electrodes for enhancement. Besides, the whole body of the provided earth electrode is directly connected with the earth and is buried; and one end of the earth electrode is connected with a protected body. According to the invention, the earth electrode has advantages of good plasticity, excellent conductive performance, stable resistance, strong tensile strength, acid and alkali resistance, high and low temperature resistance, long service life, convenient installation and friendly environment. And the earth electrode can be widely applied to various fields like electric power, communication, transportation, finance, petrochemistry, and a building system and the like for lightning and static resistance.

Description

technical field [0001] The invention relates to a carbon fiber lightning protection, anti-static and anti-breakdown grounding electrode. Background technique [0002] At present, there are many kinds of lightning protection ground electrodes, including metal, non-metallic graphite, and hybrid. These products all have drawbacks to varying degrees. Metals are not corrosion-resistant, especially in soils with high salinity and chloride ions, which are easily damaged by corrosion and fail, resulting in high cost, high energy consumption, emission of toxic substances, and environmental pollution. The service life is short; although the manufacturing cost of non-metallic graphite grounding electrodes is lower than that of metals, it is easy to break and break, which is inconvenient for construction. In densely populated and clustered places, mountainous areas and rocky areas with high soil resistivity, due to poor surface environment and limited construction conditions, the tradi...
