Abstract
The utility model discloses a ground device of a tower, which comprises a closed ring composed of galvanized flat steels or round steels and at least two radial grounding bodies connected with the closed ring in a welding manner; one end of the radial grounding body is connected with the closed ring in a welding manner, and the other end of the radial grounding body extends outwards; and the leg of the tower is arranged in the closed ring, and the radial grounding body is composed of one or more than one graphite modules. The ground device has advantages of good conductivity, non-toxic, non-pollution, good acid and alkali resistance, strong corrosion resistance, long service life, simple construction and small work amount. With the adoption of the utility model, the grounding resistance can be greatly reduced, the excavation length of a grounding groove can be shortened, the grounding resistance of the tower can be easily reduced in the area with high resistivity of soil, and the greatly shortened length of the excavation of the grounding groove is beneficial for protecting the environment, maintaining water and soil, simplifying the construction, reducing the work amount and saving investments.
Description
Technical field
The utility model relates to a kind of earthing device, particularly relates to a kind of earthing device of shaft tower.
Background technology
The overhead transmission line tower grounding is most important to the safe and stable operation of electric power system, and reducing pole tower ground resistance is the major measure that improves line lightning resisting level, reduces lightning outage rate.Owing to the high lightning stroke flashover accident that produces of pole tower ground resistance is quite a lot of, many in the past shaft towers that are positioned at mountain area, the higher area of soil resistivity, its earth resistance is difficult to reach acceptability limit, there is the earth resistance of many shaft towers higher, cause line lightning resisting level low, thunder and lightning often taking place attack directly, cause line tripping, has influenced the safe and stable operation of electrical network.
Existing earthing device adopts each shaft tower leg to be provided with independently more, and little Q-RING adds common round steel radioactive ray as earth electrode.Existing earthing device is difficult to reach the grounding requirement of shaft tower in high soil resistivity and earth electrode length limited system area; even it is also longer at common regional earth electrode; ground slot excavation length is long; quantities is big; be unfavorable for environmental protection and water and soil conservation, also increased quantities and initial cost greatly simultaneously, and the common round steel radioactive ray earth electrode of ubiquity need ray very long; and the shortcoming perishable, that useful life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of earthing device of shaft tower.
The purpose of this utility model is implemented by following technical scheme, a kind of earthing device of shaft tower, it includes the closed-loop that is made of zinc-coated flat steel sheet or round steel, at least 2 ray earth electrodes that are welded to connect with described closed-loop, one end and the described closed-loop of described ray earth electrode are welded to connect, the other end of described ray earth electrode stretches out, and all shaft tower legs are positioned at closed-loop, and described ray earth electrode is made up of 1 or an above graphite module.
When described ray earth electrode was made up of two or more described graphite modules, adjacent two described graphite modules connected by bolt.
Described ray earth electrode is positioned at the ground connection groove, be provided with the infiltration bed of material between described ray earth electrode and the described ground connection groove bottom land, the connection gap of adjacent two described graphite mo(u)ld interblocks is filled with graphite-filled material, good and prevent corrosion of steel to reach ground connection, gap between described ray earth electrode and the described ground connection groove is filled with backfill soil, described backfill soil is filled to equal with ground, should sprinkle water compaction in layers in right amount when filling described backfill soil.
Described closed-loop and described ray earth electrode weld are enclosed with described graphite-filled material, to guarantee welding reliability and corrosion resistance.
Advantage of the present utility model is, the utlity model has good conductivity, nontoxic, pollution-free, and antiacid alkali, corrosion resistance are strong, long service life, and construction is simple, and quantities is little.By adopting the utility model can reduce the excavation length of earth resistance and shortening ground slot significantly; can reduce the earth resistance of high soil resistivity shaft tower at an easy rate; it is simple that the significantly shortening of ground slot excavation length helps environmental protection and water and soil conservation and construction; reduce quantities, save investment.
