Carbon fiber graphite grounding connector and manufacturing method thereof

Abstract

The invention relates to a carbon fiber graphite grounding connector which comprises carbon fibers, wherein the carbon fibers are glued into one row through first conductive glue; a puffing furnace is used for puffing graphite into graphite worms; the graphite worms are respectively compounded on upper and lower sides of the carbon fibers, and then the carbon fibers are pressed to form graphite paper; the graphite paper is cut into strips and then the strips are rolled, so that the graphite lines are prepared; the mass ratio of the graphite to the carbon fibers to the conductive glue is (77-83):(10-12):(0.5-1.5); the carbon content of the graphite is more than or equal to 99.9%; the graphite lines are arranged in parallel so as to form a line core; the graphite lines are weaved into a weaved conductive layer on the periphery of the line core. The carbon fiber graphite grounding connector provided by the invention has excellent conductivity and surge current tolerance, reliable corrosion resistance, stable mechanical structure, high thermal stability, convenience in transportation and construction and high soil compactness.

Description

technical field [0001] The invention belongs to the field of lightning protection system protection, and in particular relates to a carbon fiber graphite grounding body. Background technique [0002] At present, my country's lightning protection grounding body is divided into two types: metal and non-metal. Metal lightning protection grounding bodies have a long history and are widely used. The most widely used are galvanized steel products, followed by copper-plated, pure copper, and alloy products that are less used; non-metallic grounding bodies are mainly resistance-reducing module products. [0003] Through research and relevant data, it is shown that galvanized iron and steel products are widely promoted and applied in my country's lightning protection grounding body, accounting for more than 99.7% of the market. Copper-plated, pure copper, alloy, resistance-reducing modules and sintered carbon rod products, although the above-mentioned products have excellent electri...

AI Technical Summary

Problems solved by technology

Copper-plated, pure copper, alloy, resistance-reducing modules and sintered carbon rod products, although the above-mentioned products have excellent electrical conductivity, due to serious environmental pollution, high energy consumption, and waste of materials, they are less used in society, and they all exist to varying degrees. Problems, such as: representative galvanized steel products are not corrosion-resistant, easy to rust, increase the grounding resistance and cause lightning accidents, short service life (about 5 years), frequent renovation, waste of materials, land, and serious funds, In addition, the production of grounding bodies will also discharge toxic waste liquid, pollute the environment, and consume high energy

Carbon rod products have complex manufacturing process, high energy consumption, serious environmental pollution, poor toughness, high brittleness, easy to break, metal connecting wires are easy to rust and damage, and installation and connection are difficult

At present, in our country, all units that use the above-mentioned traditional lightning protection grounding body are deeply troubled and harmed by product problems to varying degrees, but this problem has not been solved in our country so far.

The only way for users is frequent inspection and frequent replacement. This method is expensive and wastes materials and land. This is not in line with my country's industrial development policies of energy conservation, emission reduction, environmental protection, and high production capacity. It is contrary to the strategy of fast and sound construction and development of the national economy

[0004] Therefore, people have invented a flexible graphite lightning protection grounding body, but its mechanical strength is low, and the metal fixing parts used for binding at both ends also have the problems of not being corrosion-resistant and easy to rust
