10 Pair Earth Connection Module is a grounding body mainly made of non-metallic materials. It is composed of non-metallic minerals and electrolytic substances with good conductivity and stability. The affinity in the soil is poor, and the surface of the metal body is prone to rust and the grounding resistance changes. When there are too many organic substances in the soil, it is easy to form the phenomenon that the surface of the metal body is covered by ink, resulting in the weakening of electrical conductivity and efflux ability, increasing the It increases the diffusion area of the grounding body itself, reduces the contact resistance between the grounding body and the soil, and has strong moisture absorption and moisturizing ability, which reduces the resistivity of the surrounding soil, increases the dielectric constant, and reduces the interlayer contact resistance. Small, corrosion resistance is enhanced, so it can obtain smaller grounding resistance and longer service life.
(1) Reduce contact resistance. The main material of the grounding module is similar to the physical structure of the soil, and can be integrated with the soil, so that the effective contact area between the grounding body and the soil is many times larger than that of the metal grounding body, which increases the effective diffusion area of the grounding body and greatly reduces the The contact resistance between the grounding body and the soil can significantly improve the grounding efficiency and reduce the land area occupied by the grounding grid.
(2) Stable ground resistance. The grounding module itself has strong hygroscopic and moisturizing ability, which keeps the surrounding soil moist and ensures that the grounding module can effectively conduct electricity. Therefore, stable grounding resistance can be provided.
(3) Reduce ground potential counterattack. The non-metallic material of the grounding module forms a relatively gentle low-resistance area between the metal and the soil with a huge difference in resistivity. When a large current is impacted, the transient potential gradient of the grounding body and the grounding wire can be reduced, and the step voltage and the step voltage can be reduced. Contact voltage to reduce the probability of ground potential counterattack.
