Abstract

The utility model relates to a grounding device, particularly to a branching type grounding device. The grounding device comprises a vertical conductive connecting strip and a first grounding strip vertically connected with the conductive connecting strip, wherein an upper end of the conductive connecting strip is connected with a grounding body. The grounding device is characterized in that a plurality of second connecting strips in a parallel arrangement mode are arranged at the first grounding strip; and a spacing distance exists between each two adjacent second connecting strips. According to the grounding device provided by the utility model, because the multiple second connecting strips are additionally arranged, the contact area with the ground is increased and diffusivity of impulse currents can be enhanced; and under the circumstances that the length of a ground wire is not increased, impulse grounding impedance can be reduced. And the provided grounding device is especially suitable for an area with high earth resistivity.

Description

Branch's formula earthing device
Technical field
The utility model relates to a kind of earthing device.
Background technology
Ground connection is an important ring of electric power system, is ensureing the normal operation of electric power system.Particularly in high soil resistivity, relatively poor to the diffusing stream ability of earth current because of soil, make impedance ground excessive, influence the safe operation of electric power system.When transmission line is subjected to impulse current, during as generation thunderbolt or earth fault, be prone to accidents.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, and branch's formula earthing device is provided, and to reduce impedance, improves the stream ability purpose of loosing.For this reason, the utility model is taked following technical scheme.
Branch's formula earthing device, comprise conduction intercell connector that vertical upper end can be connected with earth electrode, with conduction intercell connector first earthing strip connected vertically, it is characterized in that: described first earthing strip is provided with many second earthing strips, there is spacing distance in the second earthing strip parallel arrangement between adjacent second earthing strip.Many second earthing strips of setting up increase the contact-making surface with the soil, can strengthen the diffusivity of impulse current, under the situation that does not increase earth connection length, can reduce the earthing device that impacts impedance ground, are particularly useful for the earthing device of high soil resistivity.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
Described second earthing strip is perpendicular to conduction intercell connector and first earthing strip, and the mid point of second earthing strip is connected with first earthing strip, and the two ends of second earthing strip are taper, and the lower end of first earthing strip is taper.
Described first earthing strip is provided with many 3rd vertical earthing strips, and the lower end of the 3rd earthing strip is taper.Set up the 3rd earthing strip, further strengthen the diffusivity of impulse current.
The 3rd earthing strip is established in the junction of first earthing strip and second earthing strip, and the upper end of the 3rd earthing strip links to each other with first earthing strip.
The conduction intercell connector is provided with many first earthing strips, and first earthing strip is radial and arranges.
Between conduction intercell connector and first earthing strip, between first earthing strip and second earthing strip, be connected by welding between first earthing strip and the 3rd earthing strip.Realize that the three reliably is electrically connected.
Beneficial effect: many second earthing strips of setting up, can strengthen the diffusivity of impulse current, under the situation that does not increase earth connection length, can reduce the earthing device that impacts impedance ground, be particularly useful for the earthing device of high soil resistivity.
