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
The present invention relates to a kind of carbon fibre lightning protection, antistatic, the anti-earth electrode that punctures.
Background technology
Lightning protection is extremely of a great variety at present, comprises metal species, nonmetal graphite class, mixes class etc.All there is drawback in various degree in these products, and metal species is not corrosion-resistant, particularly in the high soil of saline and alkaline and chloride ion content, very easily are corroded to damage and lost efficacy, cause expensive, highly energy-consuming, the discharging noxious substance, contaminated environment, useful life is short; Though nonmetal graphite class earth electrode manufacturing cost reduces than metal species, be easy to rupture and lose, be not easy to construction.In place and high mountain area, the petrographic province of soil resistivity densely populated, that housing-group is concentrated, poor because of ground surface environment, execution conditions are restricted, and traditional ground connection technology pattern is difficult to meet the demands.
Summary of the invention
The present invention aims to provide a kind of lightning protection that utilizes the carbon fibre manufacturing to form, the anti-static grounding utmost point; To overcome the drawback that at present existing production technology and product exist; Further reduce production costs, improve product useful life, make product can adapt to abominable more complicated operating mode.
The present invention adopts high purity graphite that carbon fibre and high temperature expand to mix the strip of working out, band shape, rope form, cylindric etc.; Its length can be decided with operating mode is installed; And can add wires such as stainless steel wire, copper wire, alloy silk to increase earth electrode intensity, and ground connection is integral structure very, and entire body directly is embedded in the soil; One end adds joint, and is linked to each other by protective.
The earth electrode flexibility that the present invention relates to is good; Tensile strength is high, and bendable is converted into arbitrary shape and buries underground, has reduced difficulty of construction; Can form excellent contact with various types of soil, rock well; Bigger with effective contact area of soil than traditional metal earth electrode, increased the wandering area of earth electrode itself, greatly reduce the contact resistance of earth electrode and soil.
Carbon fibre that the present invention adopted and high purity graphite basic composition is carbon, and physicochemical property is stable, anti-high and cold high heat; Its conductivity does not receive seasonal effect, has excellent corrosion resistance simultaneously, and environment is not polluted; Be environment-friendly products; Play the wire material surface of humidification simultaneously and also do corrosion-resistant treatments, the overall corrosion resistance of this earth electrode is good, and can reach more than a century useful life.
Remarkable advantage of the present invention is that tensile strength is high, and flexible good, anticorrosive, electric conductivity is good, and anti-big power frequency and impulse current impact, and it is lower to compare pure graphite-structure resistance, high-low temperature resistant, and long service life, energy-conserving and environment-protective, convenient for installation and maintenance.
Product of the present invention can be used for working earthing, safety ground and lightning protections such as power plant, transformer station, switchyard, ultra-high-tension power transmission line, electric railway, telecommunications, mobile communication base station, microwave relay station, ground satellite receiving station, radar station; Working earthing and protective earthings such as valuable precision instrument, computer room equipment, post and telecommunications program-controlled equipment, radio and television equipment, electromedical equipment; Lightning protections such as various skyscrapers and tall and big structures, showplace ancient building, tall and big memorial tower; And petroleum transportation pipeline and oil gas jar, flammable and explosive substance warehouse lightning protection.
