Corrosion is the loss causing 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 corroding 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.
Common metal earth electrode is only provided with a fixing hole, and Earthing Reliability is poor, and useful life is short, perishable, even there will be stolen situation, and power department only way is exactly diligent measurement, diligent inspection, diligent replacing, expends a large amount of man power and materials.
Utility model content
The purpose of this utility model is to provide a kind of power circuit corrosion-resisting grounding device, and this device Earthing Reliability is high, good corrosion resistance, long service life.
The technical scheme in the invention for solving the technical problem is: a kind of power circuit corrosion-resisting grounding device, comprise stainless joint and earth strip, described stainless joint is pressed on one end of described earth strip by punch press, be set side by side with two fixing holes on stainless joint; Described earth strip is rectangular-shaped, and earth strip comprises graphite earth strip and stainless steel wire surrounding layer; Stainless steel wire surrounding layer consists of outer volume in many stainless steel wires of graphite earth strip outer surface.
Further technical scheme is: described graphite earth strip comprises the main heart yearn of graphite and graphite line surrounding layer, and graphite line surrounding layer consists of with outer envelope curve outer volume in the many of the main heart yearn outer surface of graphite.
Further technical scheme is: in the main heart yearn of described graphite, graphite line surrounding layer and stainless steel wire surrounding layer, all sandwich for strengthening flexible supporting wire.
Preferred: described supporting wire is carbon fiber or nickel wire.
Preferred: the quantity of described outer envelope curve is 16.
Preferred: the width of described graphite earth strip is 40mm, the thickness of graphite earth strip is 8mm.
Compared with prior art, the utlity model has following beneficial effect:
1, stainless joint is provided with two fixing holes, and more reliable compared with the earthing device ground connection of traditional single fixing hole, fail safe is higher.
2, be provided with stainless steel wire surrounding layer, graphite earth strip is played a protective role, extend the useful life of earthing device.
3, good conductivity, corrosion-resistant, high temperature resistant, easily install, non-maintaining, pollution-free.
4, adopt nonmetallic materials, avoided stolen risk.
5, in power circuit life cycle management, earthing device, without changing or overhaul, can significantly reduce operation expense, improves electric network reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model outside;
Fig. 2 is the structural representation of the utility model inside;
