The grounding moduleis a grounding body with carbon material as the main body. It is composed of non-metallic minerals with good conductivity and stability. The grounding module can be divided into plum-shaped grounding module and cylindrical grounding module according to the shape of the product. , Square grounding module, Leikeshi grounding module.
1. The main material of the grounding module is similar to the physical structure of the soil and can be integrated with the soil. 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 dissipation area of the grounding body and greatly reduces the contact resistance between the grounding body and the soil. Therefore, it can significantly improve the grounding efficiency and reduce the occupation of the ground network. Land area.
2 .The grounding module itself has strong moisture absorption and moisturizing ability to keep the soil around it moist, ensuring that the grounding module effectively exerts its electrical conductivity; at the same time, the conductive properties of the conductive objects in the grounding body are not affected by seasonal changes such as dry humidity, high and low temperatures. Therefore, stable ground resistance can be provided.
3.The non-metallic material of the grounding module forms a relatively smooth low-resistance area between the metal and the soil with a huge difference in resistivity. When a large current impacts, it can reduce the temporary potential gradient of the grounding body and the grounding wire and reduce the stepping. Voltage and contact voltage reduce the probability of ground potential counterattack.
