Long-acting earthing device

Abstract

The invention discloses a long-acting earthing device comprising a metal wiring terminal and an earthing main body. The earthing main body comprises an ion bin and a water-logging box. The inside of the ion bin is of a cavity structure in which a conductive ion material is placed; and the inside of the water-logging box is of a cavity structure. Both the ion bin and the water-logging box at least comprise a cavity. The invention has the advantages of effectively retaining and improving the humidity of soil for a long term and remarkably improving the resistance-reducing effect and the diffuse effect of the earthing device for a long term; and a metal material on the earthing device cannot be corroded, thus the service life of the long-acting earthing device is remarkably prolonged.

Description

technical field [0001] The invention relates to the fields of lightning protection and safe electricity use, in particular to a non-metal long-term grounding device with good resistance-reducing effect and long service life. Background technique [0002] The current non-metallic grounding module is widely used because it is more convenient and simple than using angle steel, flat steel and drag-reducing agent, but some shortcomings are also found in use: First, the non-metallic body of the grounding module contains conductive ionic materials , the conductive ions are in direct contact with the metal pole core. Due to the influence of chemistry, especially electrochemical corrosion, the pole core is severely corroded. will rot. The second is that the non-metallic body of the grounding module has very limited water absorption and water retention capacity due to the cured binder material that limits the function of the water-absorbing material, making it impossible to effective...

Problems solved by technology

[0002] The current non-metallic grounding module is widely used because it is more convenient and simple than using angle steel, flat steel and drag-reducing agent, but some shortcomings are also found in use: First, the non-metallic body of the grounding module contains conductive ionic materials , the conductive ions are in direct contact with the metal pole core. Due to the influence of chemistry, especially electrochemical corrosion, the pole core is severely corroded. will rot

Second, since the binder material is cured, the function of the water-absorbing material is limited, and the non-metallic body of the grounding module has a very limited water-absorbing and water-retaining capacity, and it is impossible to effectively increase and maintain the moisture of the surrounding soil

The third is that the migration of conductive ions inside the grounding module is limited after the binder material is cured, and the penetration ability of conductive ions is limited. Except for the surface, it is difficult for the conductive ions inside the grounding module to penetrate out, so the resistance reduction effect of the grounding module is very good. limited

[0003] In addition, although the technical solution disclosed in the patent application number 200810068846.3 technically solves the above problems, the product only relies on capillary pores and ion chambers to absorb water, and its ability to absorb and retain water is limited, so it cannot effectively maintain the moisture in the surrounding soil for a long time , and relying on the ion chamber to store water will accelerate the rapid dissolution and loss of conductive ionic materials and shorten the service life of the product, so it is difficult for the product to maintain and reduce the grounding resistance value of the ground grid stably for a long time
