Abstract
The utility model provides a power line corrosion resistance grounding device which solves the problems of short service life and easy corrosion of a metal grounding body in the prior art. The power line corrosion resistance grounding device comprises a graphite line and a stainless steel joint which is pressed at one end of the graphite line through a punch. The graphite line comprises a main core line and a number of outer wrapping lines which are woven on the outer surface of the main core line. Support filaments which are used for reinforcing flexibility are clipped into the main core line and the outer wrapping lines. According to the utility model, the power line corrosion resistance grounding device has the advantages of good conductivity, high temperature resistance, easy installation, no maintenance and no pollution; by using a non-metallic material, the risk of theft is avoided; the grounding device does not need replacement or heavy repair in the whole life cycle of a power line; operation and maintenance costs can be greatly reduced; and the grid reliability is improved.
Description
Technical field
The utility model relates to power domain, particularly a kind of power circuit earthing device.
Background technology
Grounding system is the basic guarantee of safeguarding the power system security reliability service, guaranteeing operations staff and electric equipment safety, and the earth resistance that reduces the tower grounding device is a very important measure that improves line lightning resisting level.China's electric power line pole tower generally adopts the galvanized steels such as round steel, band steel as earth electrode, underground owing to being embedded in, moving after several years will rust corrosion, reduced cross-sectional area even ruptures, and causes pole tower ground resistance to raise, earthing device performs practically no function, and brings hidden danger for the power circuit safe operation.
Corrosion is the loss that causes due to material and environment reaction, and corrosion process is divided into chemistry, electrochemical and physics.Be embedded in the corrosion of metal in soil, the category that belongs to electrochemical corrosion, the soil water that is dissolved with salt and other mineral matters plays electrolyte solution, but soil corrosion is more complicated than electrolyte corrosion, because the effect earth electrode diameter that corrodes constantly reduces, the thermal stability of earth electrode and electric conductivity all can constantly reduce, and surpass certain time limit, the earth electrode fracture that will be corroded.
The common metal earth electrode is short useful life, and is perishable, even stolen situation can occur, and the power department only way is exactly diligent measurement, diligent inspection, the diligent replacing, expends a large amount of man power and materials.
The utility model content
The utility model proposes a kind of power circuit corrosion-resisting grounding device, solved in prior art short, corrosion-prone problem in metal earth electrode useful life.
The technical solution of the utility model is achieved in that
A kind of power circuit corrosion-resisting grounding device comprises graphite line and is pressed on the stainless joint of described graphite line one end by punch press; Described graphite line comprises envelope curve outside main heart yearn and outer many of compiling in described main heart yearn outer surface; Described main heart yearn and outer envelope curve inner clamps enter for strengthening flexible supporting wire.
Alternatively, the diameter of described main heart yearn is 14-16mm.
Alternatively, the diameter of described graphite line is 20 ± 2mm.
Alternatively, the number of described outer envelope curve is 16.
Alternatively, described supporting wire is carbon fiber or nickel wire.
The beneficial effects of the utility model are:
(1) good conductivity, high temperature resistant, easily install, non-maintaining, pollution-free;
(2) adopt nonmetallic materials, avoided stolen risk;
(3) earthing device need not to change or overhaul in the power circuit life cycle management, can the decrease operation expense, improve electric network reliability.
