Abstract
The utility model discloses a non-metallic composite carbon fiber copper-coated grounding material, which is a grounding material. The grounding material comprises a strip carbon fiber base material with a cross section in any shape, and an axial surface of the carbon fiber base material is coated by a metal copper layer. As carbon fiber is a non-metallic material, corrosion prevention is not a problem, and electrochemical corrosion between the carbon fiber and other metals does not happen. Thus the grounding material is suitable for use in hidden underground projects, and there is no need for repetitive maintenance work such as overhauls, so that usage costs are low. Besides, the carbon fiber base material effectively enhances conductive performance and mechanical strength of the grounding material, and the excellent mechanical strength can reduce the risk of being stolen in later usage. And thanks to the special natural toughness of the carbon fiber base material, the grounding material does not deform during coiling and storage and extends naturally during installation, so that workload of installation is reduced. Moreover, the grounding material is simple in structure, suitable for industrial production, and easy to promote.
Description
Technical field
The utility model relates to a kind of earthing material, and in particular, the utility model relates generally to a kind of nonmetal carbon fiber reinforce plastic copper-plated ground material.
Background technology
At present, conventional earthing material mainly with galvanized steel bar or band steel, copper facing band steel and at ordinary carbon steel external coating nano-carbon anticorrosion conductive coating to reach antiseptic effect.Yet in actual use, all there is different defects in aforesaid three kinds of earthing materials, the factory length that for example galvanized steel bar or band steel are general is 6 to 9 meters, galvanized layer thickness is about 60 to 70 microns, only have 8 to 15 years the service life in soil, in construction, the place of grounding head adopts electric welding, because the high temperature of electric welding has destroyed zinc coat, even if adopted antiseptic and rustproof measure, the place of joint is also the weakest link of whole earthing device.The electric conductivity of galvanized steel only has 8.6% of copper material in addition, it is 1/3 of copper plated steel, therefore when design in order to increase electric conductivity and to improve thermal stability, the material section of using is large especially, every meter of weight is 3.8 to 5 kilograms of left and right, the transformer station of a 220KV for example, nonrecoverable steel are more than 30 tons.The extra charges such as the transportation bringing thus, construction, installation, cause engineering cost significantly to raise.Therefore, generally adopt the earth mat of galvanized steel earthing material, about overhaul in 8 to 10 years once, northern area about left and right overhaul in 15 years once in southern area.The spent manpower and materials of overhaul exceed an expense to twice than newly-built ground network.Galvanized steel bar or band steel mainly be take steel as base material in addition, cathode copper 250 to 300 microns of surface coverage one decks, factory length is from 20 meters to 100 meters, and joint quantity is few, electric conductivity and the antiseptic property of material have been improved, can reach more than 30 years theoretical service life, in at present conventional earthing material, belong to comparatively advanced earthing material, but still have its weak point, its major embodiment both ways, on the one hand because copper plating (flat) steel is also that the metallic cover that two kinds of current potentials do not wait forms, if when construction or transportation, the coating of outer surface is damaged, after being embedded in soil, breakage is two kinds of different metals, according to the current potential ordinal number of copper steel material, can form a potential difference with about 0.7 V, produce electrochemical action and cause corrosion, this is while being connected to each other due to grounding electrode that copper and steel form, when the distance of copper and steel more approaching, its internal resistance is less, the electric current flowing through is larger, cause the rate of corrosion of steel to rise, etching extent also increases.When copper plating (flat) steel substrate weightlessness reaches more than 50%, earth mat enters ground if any fault current, can cause earth mat or draw the fusing of reaching the standard grade, and causes power failure or transformer such as burns at the security incident.On the other hand because copper facing round steel diameter is at 14 millimeters to 18 millimeters, 100 meter of one volume of length, in the time of construction, need to it is stretching, cause thus workload and work difficulty to increase, round steel by artificial alignment, glacing flatness is too poor, does not meet the requirement of heat release welding, therefore welds difficulty large, welding point mortality is high, causes a large amount of wastes.Adopt the carbon steel of brushing nano-carbon anticorrosion conductive coating in reality simultaneously, especially complicated high resistivity mountain area, ground connection ditch had both dug out-of-flatness, also dig not straight, the round steel that plasticity is not strong or band steel etc. must have on the stone that part withstands on left, right-hand or below, cannot brush and put in place, steel, nano-carbon anticorrosion conductive coating, water and soil will form primary cell, using steel earth electrode as anode, are eroded.Therefore adopt nano-carbon anticorrosion conductive coating can accelerate conversely earth electrode corrosion, although may protect a part of earth electrode to avoid corrosion, accelerated the corrosion rate of another part earth electrode, overall, real in corrosion earth electrode, shorten its life-span.Based on aforementioned three kinds of existing deficiencies of earthing material, be necessary to do further improvement and research for structure and the material of earthing material.
Utility model content
