Description
Technical field
The utility model is related to earthing device of electrical equipment, and in particular, to a kind of long-effective corrosion Novel connecting earth polar.
Background technology
Thunder and lightning is a kind of common electric discharge phenomena of nature, there is millions of lightnings, annual thunder in nature every year
Economic loss improves year by year caused by electricity, and especially in power industry, the development of extra-high voltage leads to the structures such as shaft tower increasingly
Height, the incidence of lightning stroke, which also has, to be correspondingly improved.But it trips in order to prevent because power grid is struck by lightning, polarity of ground energy
Quality is particularly important, and an earthing or grounding means with rationally, can not only correctly provide safeguard, moreover it is possible to reduce engineering for effective lightning protection
Construction cost.In order to meet Operation of Electric Systems stability requirement, earthing pole should be able to meet wanting for system safe and stable operation
Ask, prevent lightning stroke trip accident from occurring, it is ensured that the safety of power supply with it is reliable.
Earthing pole is mainly embedded in underground, and in the construction of earthing pole, the size of earth excavation is directly related to earthing pole
Construction period and manpower and materials cost.Earthing pole at this stage largely uses in power grid, and all kinds of shaft towers, substation have
Corresponding earthing or grounding means, the earthing pole used include made of many novel resistance-lowering materials, and such Master Cost is higher, in power grid
Middle popularization is extremely uneconomical.The patent that for example number of patent application is 201320752764.7《A kind of novel corrosion resistant earthing pole》It carries
And covering one layer of novel conductive material high molecular polymer pyrroles's film in ground connection pole surface, this kind of macromolecule membrane, which avoids, to be connect
Earth polar itself is in direct contact with corrosive environment, can extend the service life of the earthing pole of copper clad steel type, but such high score
Sub- material price is high, and coating processing is complicated, the somewhat expensive for the earthing pole used on a large scale.Patent《Substation grounding
Protective device》（Number of patent application 201610637224.2）A kind of ground protection dress mainly for substation is proposed in one text
It sets, as long as change ground connection proximate matter surface shape is utilized in the present apparatus, increases overstriking earthing material to reach after long-time is corroded
Grounding requirement can still be met.Such scheme uses the safety coefficient of bigger, does not meet the economical and efficient that existing power grid proposes
The thought of sustainable development, while more materials are used, the solution of these counterviolences is technical relatively low.Patent application
Number be 201210495831.1 patent《Corrosion-free conduction resistance-lowering material and its earth device without maintenance》Disclose a kind of no corruption
The conductive resistance-lowering material of erosion, such earthing or grounding means directly wraps metal material with other materials, although appearance does not have etching problem
