Embodiment Construction

[0020] Its working principle is: after the grounding module and the grounding grid described in the present invention are welded together, they are buried and watered, and the water penetrates the shell of the porous plate and enters the filling medium in the shell. The filling medium interacts with water. On the one hand, the high water retention material absorbs water and keeps the whole module moist; The etchant is used to reduce the corrosion rate of the metal skeleton and the porous plate shell by conductive ions as much as possible. The sacrificial anode frame and the porous plate shell are welded together to protect the ground grid and slow down corrosion in the form of sacrificial anode. When working, the conductive ions in the filling medium penetrate the shell of the porous plate and infiltrate into the surrounding soil under the action of water, forming a root-like conductive path and expanding the contact area with the soil.

Abstract

The invention discloses a corrosion-preventing and resistance-reducing grounding module. The straw pulp paper or the wood pulp paper is laid on the inner surface of a shell, the middle in the shell is provided with a sacrificial anode, and a sacrificial anode inner core is embedded into the sacrificial anode; and an inner cavity between the sacrificial anode and the shell is provided with a filling medium. The invention adopts the sacrificial anode using iron or copper as the inner core as a framework, adopts a high-water-retention material, a forming material, a metal corrosion inhibiting agent and a conducting electrolyte as the filling medium, adopts a porous plate made of a thin-wall sacrificial anode material as the shell and can prevent the corrosion of a grounding net and effectively reduce the resistance of the grounding net.

Description

technical field [0001] The invention relates to the field of lightning protection and grounding facilities, in particular to a grounding module which can prevent corrosion of the grounding grid and reduce the resistance of the grounding grid. Background technique [0002] The grounding module is one of the effective ways to reduce the grounding resistance of the grounding grid. The use of the grounding module avoids the side effect of corrosion of the grounding grid caused by the use of resistance reducing agents, but due to its limited area, its resistance reducing ability is limited in some high resistance areas. [0003] The results of existing patent searches show that the disclosed patented grounding module achieves the purpose of reducing resistance from two aspects: one is by increasing the surface area of ​​the module, as described in the application (patent) Nos. 200820203333.4 and 200720128250.9; Conductive ions increase the conduction function of the current, as ...
