Problems solved by technology

These products have disadvantages to varying degrees. Metals are not resistant to corrosion, especially in soils with high saline-alkali and chloride ion content, they are easily damaged by corrosion and fail, resulting in high costs, high energy consumption, toxic emissions, and environmental pollution. Short service life; although the manufacturing cost of non-metallic graphite ground electrodes is lower than that of metal ones, it is easy to break and break, which is not convenient for construction

Abstract

The invention discloses an anti-corrosion lightning protection earth electrode which is obtained through performing mixed braiding on carbon fibers and copper wires for obtaining a braided wire, and furthermore applying an anti-corrosion coating on the surface of the braided wire. The anti-corrosion coating comprises the following raw materials by weight: 2-35 parts of modified bisphenol A-type epoxy resin, 0.5-12 parts of fluorocarbon resin, 0.1-2 parts of dimethicone, 10-56 parts of diluent, 2-20 parts of curing agent, 0.5-5 parts of silane coupling agent, 1-14 parts of silicon micropowder,and 5-24 parts of antimony doped tin oxide. The invention further discloses a preparation method of the anti-corrosion lightning protection earth electrode. According to the lightning protection earthelectrode, through protection of the surface coating, high conductivity and excellent corrosion resistance are realized. Furthermore service life is prolonged. The anti-corrosion lightning protectionearth electrode has wide market prospect.

Description

technical field [0001] The invention relates to the technical field of electrical grounding, in particular to a corrosion-resistant lightning protection grounding electrode and a preparation method thereof. Background technique [0002] Electricity plays an extremely important role in human production and life. However, lightning, as a natural phenomenon in nature, often produces super-strong current and voltage, which is easy to cause damage to electrical equipment, thus causing a lot of economic losses to human beings. Therefore, in order to ensure the safety, stability and smoothness of transmission lines, it is particularly important to carry out lightning protection work. People often carry out lightning protection work by setting up grounding devices. Grounding is the most important link in lightning protection projects. The function of protective grounding is to make a good metal connection between the uncharged metal parts of electrical equipment and the grounding bo...
