Abstract
The utility model discloses a lightning-protection grounding device for an electric power line. The lightning-protection grounding device comprises a ground lead and a cylindrical grounding body. The ground lead and an upper end of the cylindrical grounding body are fixedly connected together, a certain arc inclined angle is left between the ground lead and the cylindrical grounding body, the inclined angle between the ground lead and the cylindrical grounding body is 15-25 degrees, and the bottom of the cylindrical grounding body is provided with a conical base seat. The bottom of the cylindrical grounding body is provided with the conical base seat, so the device cannot be easily pulled out, and safety factors of maintenance and running of an electric power system are improved; and the certain arc inclined angle is left between the ground lead and the cylindrical grounding body to be taken as a lightning protection angle, the protection angle provides a protection zone for the ground lead, and a good lightning protection effect can be achieved.
Description
One, technical field:
The utility model relates to a kind of earthing device, particularly relates to a kind of power circuit lightning protection earthing device.
Two, background technology:
When lightning protection earthing device is installed in electric power system, often adopt earth electrode to connect, it is that low side is the straight-bar body of tip type, and straight-bar earth electrode can insert in the earth of electric pole below easily, and then upper end is connected with ground lead.It is insecure that but straight-bar earth electrode connects, and is usually pulled out, and normally safe operation of circuit, gives full operation maintenance and bring very large potential safety hazard.
Three, utility model content:
Technical problem to be solved in the utility model is: a kind of anti-lightning strike effective, the power circuit lightning protection earthing device that can not be extracted is easily provided.
The utility model is that the technical scheme that technical solution problem is taked is:
A power circuit lightning protection earthing device, comprises ground lead and column type earth electrode, and the upper end of described ground lead and column type earth electrode is fixed together, and leaves certain circular arc angle between the two; Described column type earth electrode bottom is provided with sloped footing.
Angle between described ground lead and column type earth electrode is 15～25 degree.
Described ground lead and column type earth electrode weld together.
The utility model, owing to being provided with sloped footing in column type earth electrode bottom, can not be pulled out this device easily, has improved the coefficient of safety of electric power system maintenance operation.
The utility model leaves certain circular arc angle between ground lead and column type earth electrode, and as lightning protection angle, shielding angle is 15～25 degree, and shielding angle, for ground lead provides a protection zone, has reached good anti-lightning strike effect.
Four, accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Five, embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of power circuit lightning protection earthing device, comprise ground lead 1 and column type earth electrode 2, ground lead 1 is fixed and welded together with the upper end of column type earth electrode 2, between the two, leave certain circular arc angle, circular arc angle is 15～25 degree, in column type earth electrode 2 bottoms, is provided with sloped footing 3.
The utility model, because the bottom at column type earth electrode 2 is provided with sloped footing 3, can not be pulled out this device easily, has improved the coefficient of safety of electric power system maintenance operation; And the utility model leaves certain circular arc angle as lightning protection angle between ground lead 1 and column type earth electrode 2, and shielding angle, for ground lead provides a protection zone, can reach good anti-lightning strike effect.
