Abstract
The utility model relates to an antitheft earth electrode which comprises an angle steel earth electrode or a steel pipe earth electrode. The length of an angle steel or a steel pipe is greater than two meters; an inverted triangular angle steel is uniformly welded on the inner surface of the angle steel or is uniformly welded on the outer peripheral surface of the steel pipe; the lower end of the angle steel or the steel pipe is provided with a conical tip; conductive magnetic powder is filled in the inverted triangular angle steel; a hamming reinforcement plate is welded at the upper end of the angle steel or the steel pipe; and a jointing clamp connection hole is formed in the angle steel or the steel pipe below the reinforcement plate. The antitheft earth electrode has the advantages that 1, the inverted triangular angle steel is designed on the surface of the antitheft earth electrode, so that the contact area between the antitheft earth electrode and the soil and the pull-out resistance are increased, the problem that the earth electrode is stolen is solved and the effect of preventing an overhead power line from suffering from the lightning stroke is ensured; and 2, the conductive magnetic powder is filled in the inverted triangular angle steel, so that the electrical conductivity of the earth electrode is ensured and the resistance of the earth electrode is reduced.
Description
Technical field
The utility model relates to the set anti-theft grounding electrode of the empty lightning conducter of high voltage supply coil holder in a kind of high voltage supply net, solves stolen and the trip accident when causing the electrical network thunderbolt of earth electrode.
Background technology
Overhead ground wire earth electrode on the present high-tension electricity electric wire, it all is the depths of pounding the 1.5m-2.5m in the ground with an angle steel or steel pipe, the top is connected as earth electrode with lightning conducter by lightning-arrest wire clamp uses, because angle steel and steel tube surface smoother, the lawless person need not difficultly just can pull out and steal, cause the tripping operation of thunderbolt electrical network and large tracts of land to have a power failure, have a strong impact on user's production and the problem of household electricity.
Summary of the invention
The purpose of this utility model provides a kind of anti-theft grounding electrode, and the earth electrode that overcomes above-mentioned prior art existence is stolen, causes that the thunderbolt electrical network causes the large tracts of land tripping operation to have a power failure, and affects the problem of the normal production of user.
The technical solution of the utility model is achieved in the following ways:
The utility model comprises angle steel earth electrode or steel pipe earth electrode, the length of its angle steel or steel pipe is greater than two meters, inner surface at angle steel evenly is welded with the del angle steel, or evenly be welded with the del angle steel at the steel pipe outer peripheral face, be provided with the cone point at angle steel or steel pipe lower end, the electroconductive magnetic powder is housed in the del angle steel; Be welded with the stiffener of a hammering in angle steel or steel pipe upper end, be provided with the binding clip connecting hole at angle steel or the pipe of stiffener bottom.
Compared with the prior art the utility model has the following advantages:
1, in surface design of the present utility model the del angle steel, increased resistance long-pending with soil contact and that extract, solved the stolen problem of earth electrode, guaranteed the lightning-arrest effect of hitting of overhead power line.
2, the conductive magnetic powder of having packed in the del angle steel has been guaranteed the conductivity of earth electrode to reduce earth electrode resistance.

Accompanying drawing-structural representation of the present utility model;
1-stiffener among the figure, 2-binding clip connecting hole, 3-angle steel earth electrode, 4-del angle steel.
Embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model comprises angle steel earth electrode 3 or steel pipe earth electrode, the length of its angle steel or steel pipe is greater than two meters, inner surface at angle steel evenly is welded with del angle steel 4, or evenly be welded with del angle steel 4 at the steel pipe outer peripheral face, be provided with the cone point at angle steel or steel pipe lower end, the electroconductive magnetic powder is housed in del angle steel 4; Be welded with the stiffener 1 of a hammering in angle steel or steel pipe upper end, be provided with binding clip connecting hole 2 at angle steel or the pipe of stiffener 1 bottom.
When using the utility model, according to the electric pressure of power supply network the quantity of anti-theft grounding electrode is set, under high-voltage wire pole of 35KV 1-2 anti-theft grounding electrode can be set, under the high-voltage wire pole more than the 35KV 2-3 anti-theft grounding electrode can be set.Fixed screw on the binding clip connecting hole 2 of the binding clip of the earth connection lower end of overhead power line lightning conducter by earth connection and anti-theft grounding electrode upper end links to each other, and the upper end of earth connection links to each other with lightning conducter on being located at high-voltage line.In the rainy season that thunder and lightning is multiple, as long as there is thunder and lightning to click the high voltage supply circuit, lightning conducter at first receives high tension voltage and the electric current of thunder and lightning and passes to the earth by anti-theft grounding electrode rapidly, prevents the thunder and lightning high-voltage fence of breaking, and has guaranteed the normal operation of high-voltage fence.
