The ground wire grounded utmost point
Technical field
The utility model relates to a kind of auxiliary equipment in the electric power system, particularly a kind of ground wire grounded utmost point of electric current being introduced soil for electric power transmission line.
Background technology
Earth electrode mainly in electric power system ground connection use, be with the earthy a kind of safety appliance of power failure equipments temporary short-circuit, be an important tool that guarantees transmission line interruption maintenance operating personnel safety.Traditional ground wire grounded utmost point generally includes earth electrode and the ground wire that is welded on the earth electrode, and ground wire normally directly is welded in parallel on the earth electrode.In the use, when earth electrode inserts ground, because ground wire and earth electrode be arranged in parallel, very easily will be welded on the ground wire bending on the earth electrode, when especially running into special landforms such as hillside, cause the disconnected strand of ground wire easilier, not only shortened the life cycle of ground wire, the more important thing is concerning the operating personnel and also can bring great potential safety hazard.
The utility model content
The technical problems to be solved in the utility model provides the high ground wire grounded utmost point of a kind of performance easy to use, safe, improving the useful life of earth electrode, and fundamentally guarantees operating personnel's safety.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
The ground wire grounded utmost point comprises earth electrode and ground wire, and the upper end of described earth electrode fixedly installs a contiguous block, and described ground wire is fixedly installed on the contiguous block, and described ground wire is vertical mutually with earth electrode with the end that contiguous block is fixed.
Improvement of the present utility model is: described ground wire is welded on the contiguous block.
Further improvement of the utility model is: described contiguous block is provided with at least two through holes, and line and the earth electrode of described through hole are perpendicular; One end of ground wire is fixedly connected with the wire clamp of band screw, and the screw of described wire clamp is corresponding with the through hole of contiguous block, and wire clamp is fixedlyed connected with contiguous block by bolt.
Owing to adopted technique scheme, the obtained technological progress of the utility model is as follows.
Ground wire of the present utility model is connected with earth electrode by the contiguous block that is arranged on the earth electrode, has increased the be connected area of ground wire with earth electrode, makes the utility model more firm; The vertical setting of ground wire and earth electrode, make that ground wire parallels with ground in the process of earth electrode being inserted ground, ground wire can not contact with ground, avoided in the earth electrode insertion process, the fractureing generation of ground wire phenomenon, improve useful life of the present utility model, fundamentally guaranteed operating personnel's safety.Ground wire one end is connected by bolt with contiguous block by the wire clamp that arranges, and can change ground wire by removing bolt after ground wire damages, and does not only influence result of use of the present utility model, has also improved versatility of the present utility model.The setting of contiguous block in addition can also be used as handle, when the utility model is applied in the location of many doping of geologic structure sandstone, hand-holdable contiguous block, carry out earth electrode pound into, avoided directly holding the possibility that the easy adversary of earth electrode causes accidental injury.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1
A kind of ground wire grounded utmost point is applied in the electric power system, uses as electric current in the circuit is inserted in the soil, to guarantee staff's safety work.Mainly comprise earth electrode 1 and ground wire 2, the upper end of earth electrode 1 fixedly installs a contiguous block 3, and described ground wire is welded on the contiguous block, and described ground wire is vertical mutually with earth electrode 1 with the end that contiguous block is fixed.During use, directly the face of land is inserted in the lower end of earth electrode and get final product, arrange because ground wire is vertical with earth electrode, and parallel to the ground, therefore can not damage ground wire.When running into the harder location of geology, can hold contiguous block, with hammer hammering earth electrode, earth electrode can be pounded into underground.
Embodiment 2
The difference of present embodiment and embodiment 1 is: contiguous block is provided with two through holes, and line and the earth electrode of two through holes are perpendicular; One end of ground wire is fixedly connected with the wire clamp 4 of band screw, and the screw of wire clamp is corresponding with the through hole of contiguous block; Fixedly connected by bolt 5 between wire clamp 4 and the contiguous block 3.
