Description
Technical field
The utility model relates to a kind of grounding-for-lightning device, more specifically, relates to a kind of high-tension line lightning protection earthing device.
Background technology
Along with the development of China's electric power system, high-tension overhead line is laid also increasing.The power outage caused by transmission line of lightning strike is also increasing, in total tripping operation number of times of China's ultra-high-tension power transmission line, by being struck by lightning, the accident caused accounts for 55%-75%, especially the area frequent at lightening activity, soil resistivity is high, with a varied topography, the accident rate caused by transmission line of lightning strike is higher, and the economic loss caused is very huge, therefore, in overhead transmission line design, the research of lightning Protection Design is very important.
The earth resistance of current ground network mainly comprises: one, ground lead resistance, refers to by the resistance of the lead-in wire between earth electrode and equipment ground bus itself, and its resistance is relevant with material with the physical dimension of lead-in wire; Two, the resistance of earth electrode itself, its resistance is relevant with material with the physical dimension of earth electrode; Three, earth electrode surface and the contact resistance of soil, the contact area of the character of its resistance and soil, particle, water content, soil and earth electrode and to contact tightness degree relevant; Four, spreading resistance, from the electric current that earth electrode distally spreads the resistance of soil of process.Although earth resistance is made up of above-mentioned four partial ohmic, what play a decisive role is earth electrode surface and the contact resistance of soil and spreading resistance.
In prior art, usually adopt radioactive method to bury the copper steel plating of certain length underground as earth electrode, reduce earth resistance, this method is local preferably in soil property, place as more in earth, can reduce earth resistance well, but, in the mountain region that soil property is more severe, or the place that the many soil of stone is few, because copper steel plating cannot form good contact with the stone of surrounding, can not set up effective current spread passage, therefore, effectively earth resistance can not be reduced.
Utility model content
The utility model in order to solve diffusing effect in prior art poor, effectively cannot reduce earth resistance, the problem that simultaneously cost of earthing device is higher, and provide a kind of high-tension line lightning protection earthing device.
This high-tension line lightning protection earthing device comprises terminals, multiple earth electrode, copper wire, conductive plate, and described conductive plate is laid on below ground by level, and apart from 0.5 meter, ground; Multiple described copper wire is laid equably in described earth electrode; Coated one deck resin mold in the outside of described earth electrode; Multiple described earth electrode and level are laid on the described conductive plate electrical contact below ground.
The quantity of wherein said earth electrode is 3.
The material of wherein said earth electrode is graphite.
The diameter range of wherein said earth electrode is at 20 centimetres-40 centimetres.
The diameter of wherein said earth electrode is 30 centimetres, and the quantity of described copper wire is 5.
Following beneficial effect can be obtained by technique scheme: the diffusing effect substantially increasing lightning protection on the one hand, reduces earth resistance, simultaneously because graphite cost is lower, thus save the cost of high-tension line lightning protection earthing device.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-tension line lightning protection earthing device of the present utility model;
Fig. 2 is the sectional view of the earth electrode of high-tension line lightning protection earthing device of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of simulated earthquake apparatus for demonstrating provided by the invention and demenstration method thereof are described in detail.Here do to illustrate, in order to make embodiment more detailed, the following examples are best, preferred embodiment, also can adopt other alternative and implement for some known technologies those skilled in the art simultaneously; And accompanying drawing part is only to describe embodiment more specifically, and be not intended to carry out concrete restriction to the present invention.
Fig. 1 is the structural representation of high-tension line lightning protection earthing device of the present utility model.As shown in Figure 1, this high-tension line lightning protection earthing device comprises terminals 1, earth electrode 2, copper wire 4, conductive plate 3.Wherein earth electrode 2 is multiple, and the quantity of earth electrode is 3 in a preferred embodiment of the invention.In order to reduce the manufacturing cost of high-tension line lightning protection earthing device of the present utility model, the material of earth electrode preferably selects graphite.Conductive plate 3 usually level is laid on below ground, thus effectively reduces the contact resistance of high-tension line lightning protection earthing device and circumferentially earth.The environment laid according to high-tension line lightning protection earthing device and the character of soil, the diameter range of conductive plate 3 is from 2 meters-4 meters, and the present invention is preferably 3 meters.In addition, also according to the environment of high-tension line lightning protection earthing device laying and the character of soil, conductive plate 3 is laid on the scope apart from 0.5 meter-1 meter, ground.After conductive plate 3 is laid on below ground, make multiple earth electrode and conductive plate 3 electrical contact.
Figure 2 illustrates the sectional view of the earth electrode of high-tension line lightning protection earthing device of the present utility model.In order to effectively increase the conductive effect of earth electrode, and scattered current, in earth electrode, laid multiple copper wire equably.The diameter range of earth electrode, at 20 centimetres-40 centimetres, can select the copper wire of varying number according to the diameter of earth electrode.In embodiment of the present utility model, earth electrode is preferably 30 centimetres, and the quantity of copper wire is 5.Simultaneously in order to prevent earth electrode corrosion-vulnerable or insect bite in acid ground, and in the outside of earth electrode coated one deck resin mold 5.
Substantially increased the diffusing effect of lightning protection by technique scheme on the one hand, reduce earth resistance, simultaneously because graphite cost is lower, thus save the cost of high-tension line lightning protection earthing device.
Finally it should be noted that, above embodiment is only in order to describe the technical solution of the utility model instead of to limit this technical method, the utility model can extend in application other amendment, change, application and embodiment, and therefore think that all such amendments, change, application, embodiment are all in spirit of the present utility model and teachings.
