By using above-mentioned technical proposal, since mountain area major part belongs to high soil resistivity, transmission line of electricity bar Tower ground resistance is difficult to reach regulatory requirements, may be because insulator damages, aerial earth wire and conducting wire break caused by counterattack when by being struck by lightning Line, therefore grounding body is set the internal conductor for being formed with cavity by the technical program, by being filled in the shell of grounding body Fexible conductor in irregular shape, when lightning current by irregular fexible conductor to ground leakage current when, meeting between fexible conductor The power in irregular direction is generated, last overall power is to cancel each other out, so that lightning stroke energy is assimilated, even if being grounded In the higher soil of resistance, diffusing effectively can also be carried out to thunder energy.
Further, the fexible conductor is expanded graphite particles or conductive sponge.
By using above-mentioned technical proposal, fexible conductor is preferably expanded graphite particles or conductive sponge, on the one hand works as thunder Electric current by irregular expanded graphite or conductive sponge to ground leakage current when, meeting between expanded graphite particles or conductive sponge The power for generating irregular direction cancels each other out the power of last totality, to assimilate lightning stroke energy;On the other hand, Using expanded graphite or conductive sponge as cotton, there is certain elasticity, between expanded graphite or conductive sponge mutually Also lightning stroke impact energy can be absorbed under the spring damping of effect, it is ensured that the security protection of grounding body.
Further, it is distributed between multiple fexible conductors in the grounding body ontology multiple for reducing ground resistance Water-absorbing resin.
By using above-mentioned technical proposal, multiple suctions for reducing ground resistance are distributed between multiple fexible conductors Water-resin can keep being constantly in dampness around grounding body using water-absorbing resin, be conducive to improve connecing for surrounding soil Ground resistance condition, and reduce the ground resistance of earthed system.
Further, the both ends of the shell are opening-like, are mounted in two open ends of shell for soft graphite Dismountable closure end that line is pierced by.
By using above-mentioned technical proposal, dismountable closure end is set, is not easy the fexible conductor in shell outer It lets out, is also convenient for the merging of filler.
Further, the shell is conductor or semiconductor.
Further, the shape of the shell is cuboid or cylindrical body.
Further, erosion resistant coating is coated on the outside of the soft graphite line.
Further, at least one is arranged in the soft graphite line.
The utility model embodiment has the advantages that
Soft graphite line is arranged in the absorption grounding body of the utility model on grounding body ontology, and in grounding body ontology Multiple fexible conductors in irregular shape are filled in inside, make soft graphite line across grounding body ontology, and soft graphite line One end is pierced by the shell of grounding body ontology for connecting earthing device, and the other end is pierced by the shell of grounding body ontology for being connected to Depth of soils.By the irregular fexible conductor of filling shape in the shell of grounding body, when lightning current pass through it is irregular soft Property conductor to ground leakage current when, the power in irregular direction can be generated between fexible conductor, last overall power is to cancel each other out, To assimilate lightning stroke energy, even if can also effectively be carried out to thunder energy scattered in the higher soil of ground resistance Stream, without complicated line, structure is simple, and earthing effect is good, small in size, easy to use.
