Technical field
The present invention relates to electric system Lightning protection fields, and in particular to a kind of absorption grounding body.
Background technique
The earthing or grounding means of transmission line of electricity is maintenance power system security reliability service, ensures that electrical equipment and operations staff are pacified Full basic guarantee and important measures, earthing or grounding means includes grounding body and ground line, and has the grounding body of good impact characteristics Can by by conducting lightning currents importing underground play the role of lightning protection, provide effective protection for transmission line of electricity, thus avoid because of Lightning stroke causes power outage, and safe operation and power supply reliability to electric system all have highly important meaning.
Some geographical environment mountain ranges rise and fall at present, and height above sea level is higher, and with a varied topography, these mountain area major parts belong to high soil Resistivity area, powerline pole tower ground resistance is difficult to reach regulatory requirements, may be because of insulator caused by counterattack when by being struck by lightning Damage, aerial earth wire and conductor cord disconnection, cause line tripping.
Summary of the invention
The purpose of the present invention is to provide a kind of absorption grounding bodies, and to solve existing grounding body, there are above-mentioned insufficient Problem.
To achieve the above object, the embodiment of the present invention provides a kind of absorption grounding body, and the absorption grounding body includes Grounding body ontology and the soft graphite line being arranged on grounding body ontology, the grounding body ontology include shell and are filled in shell Internal multiple fexible conductors in irregular shape, the soft graphite line is 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 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 embodiment of the present invention has the advantages that
Soft graphite line is arranged in absorption grounding body of the invention on grounding body ontology, and in the inside of grounding body ontology Multiple fexible conductors in irregular shape are filled, soft graphite line is made to pass through grounding body ontology, and one end of soft graphite line The shell of grounding body ontology is pierced by for connecting earthing device, the other end is pierced by the shell of grounding body ontology for being connected to soil Depths.By the irregular fexible conductor of filling shape in the shell of grounding body, when lightning current is led by irregular flexibility When body is to ground leakage current, the power in irregular direction can be generated between fexible conductor, last overall power be cancel each other out, thus Lightning stroke energy is assimilated, even if effectively diffusing, nothing can also be carried out to thunder energy in the higher soil of ground resistance Complicated line is needed, structure is simple, and earthing effect is good, and it is small in size, it is easy to use.
