Grounding module

Abstract

A grounding module comprises a module body and is characterized in that the formula of the grounding module basically comprises the following components in parts by weight: 13-17 parts of coke powder, 1.5-8 parts of cement, and 0.3-5 parts of graphite powder. The formula of the grounding module further comprises 0.3-5 parts of ion releasing agent. The grounding module has the advantages that the grounding module adopts natural nonmetallic mineral materials which have excellent conductivity and soil compatibility as conducting medium of the grounding module, conductivity of the grounding module is not affected by seasons, so that stable ground resistance is provided, besides, due to the nonmetallic mineral materials, a low resistance zone which is gentle in variation is formed between metal and soil which have huge difference in resistivity, step voltage and contact voltage are lowered, probability of occurrence of ground potential counterattack is reduced, moreover, by matching an ion releaser, electrolyte can durably permeate into the soil in a high concentration mode, the goal that ground resistance can be rapidly lowered is achieved, and characteristics of the grounding module such as density, corrosion resistance, conductivity, compressive strength are enhanced.

Description

technical field [0001] The invention relates to the technology of a grounding device for conducting electricity, in particular to a grounding module connected with wires. Background technique [0002] There is a Chinese utility model patent with the patent number CN94230002.5 titled "Low Resistance Grounding Module", which discloses a low resistance grounding module, which is cast from non-metallic electrolytic gel and wrapped with a pole core inside. One or both ends of the core protrude from the module body, and it is connected with lightning protection and lightning protection equipment by fasteners. When the grounding module is long or heavy, a mesh or rod-shaped skeleton can be set in the module body to prevent breaking. The grounding resistance has the characteristics of low resistance and anti-corrosion, and its resistance change rate is less than or equal to 20% after being subjected to a large current impact. This patented technology has played a positive role in ...

Problems solved by technology

This patented technology has played a positive role in overcoming the inconvenience of using the traditional technology of resistance reducing agents. However, the low-resistance grounding module disclosed in this patent is cast from pole cores and non-metallic electrolytic gels. Because it is used as an electrode The metal pole core is located in the resistance-reducing layer as a whole, and is in contact with the electrolyte ions as a conductive substance. Not only is the corrosion serious, the service life is short, and more importantly, the raw materials and structural design of the grounding module are unreasonable, resulting in unstable conduction. Inhomogeneous; and the module is cast from the pole core and non-metallic electrolytic gel, so the firmness and strength are not high. Therefore, the raw material and structure of the low-resistance grounding module need to be further improved
