Embodiment 1
[0027] A grounding wire device, comprising a tubular conductor, one end of the tubular conductor is a tapered end 1 with a tapered structure, the other end of the tubular conductor 3 is closed, and through holes are distributed on the wall of the tubular body at intervals, The conical head of the tubular conductor is solid, and the inner cavity of the tubular body is filled with activated carbon and a drag reducing agent. In the middle, the tubular electrical conductor also includes a wire, and the wire extends into the inner cavity of the tubular electrical conductor until it reaches the solid part and is exposed at the closed end of the tubular electrical conductor. The wire 5 located in the inner cavity of the tubular electrical conductor is a bare wire, and the wire The exposed end is connected with terminal 6. The drag reducing agent is a long-term drag reducing agent, and the drag reducing agent includes fine graphite, bentonite, curing agent, lubricant, and conductive c...

The invention discloses a grounding wire device, comprising a tubular electric conductor, wherein one end of the tubular electric conductor is of a taper solid structure; the other end of the tubular electric conductor is sealed; through holes are distributed in the wall of a tubular electric conductor at intervals; activated carbon and a resistance reducing agent are filled in an inner cavity of the tubular electric conductor; the activated carbon is distributed on two ends of the tubular electric conductor; the resistance reducing agent is filled in the middle of the activated carbon on the two ends of the tubular electric conductor; the tubular electric conductor also comprises a wire; the wire stretches into the inner cavity of the tubular electric conductor, directly reaches a solid part and is exposed out of the sealed end of the tubular electric conductor; the wire located in the inner cavity of the tubular electric conductor is a bare wire; and a terminal block is connected onto the exposed end of the wire. By the adoption of the grounding wire device provided by the invention, the technical problems of grounding for lightening under various special conditions can be effectively solved; the difficult construction problem of a grounding project is solved as well; and as a grounding wire bar is directly stricken into the ground without ground groove excavation, the grounding effect under the condition of strongly corrosive geology and the grounding effect of construction in an urban limited narrow region are better.
Description
technical field [0001] The invention relates to a grounding device, in particular to a grounding wire device suitable for various geological and climate conditions. [0002] Background technique [0003] At present, excavation of trenches and trenches for power engineering grounding grids in urban areas are easily restricted by narrow urban areas and municipal planning, and at the same time, there are many restrictions on grounding construction sites under strong corrosive geological conditions. It is necessary to develop a grounding rod, which can effectively solve the technical problems of lightning protection and grounding protection under various special conditions, and solve the difficult problems of difficult construction of grounding projects, especially for grounding construction in restricted narrow areas in urban areas, strong corrosion Grounding construction under geological conditions can carry out simple and effective grounding.
