The grounding module may not be familiar to some friends, but it is used in various fields such as industrial manufacturing, chemical production, building materials, railway transportation , etc. It can be said that he plays a big role. Very versatile. This is actually a grounding object, but it is a non-metallic material. Why use non-metallic materials as grounding tools? This is because non-metallic materials have relatively strong stability and good electrical conductivity. This can make the grounding process easier and more convenient. So what exactly is it for?
The grounding 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. It solves the problem that the bodies ofMetal grounders have low affinity in acidic or alkaline soils and are prone to corrosion on the surface of the metal body, causing a change in the grounding resistance. When there are too many organic substances in the soil, it's easy. to form a phenomenon where the surface of the metal body is enveloped by ink, resulting in the weakening of the conductivity and effusion ability increases the dispersion area of the grounding body itself, reduces the contact resistance between the grounding body and the ground, and has strong moisture absorption and hydration capabilities, which reduces the resistivity of the surrounding soil. The dielectric constant increases, the interlayer contact resistance decreases, and the corrosion resistance increases, thereby achieving lower ground resistance and longer service life.
Function:
(1)? Reduce the resistance ofcontact. The main material of the grounding module has a physical structure similar to that of the ground and can be integrated with the ground, making the effective contact area between the grounding body and the ground several times larger than that of the metal grounding body, thus increasing the effective dispersion. area of the grounding body and significantly reducing the contact resistance between the ground body and the ground can significantly improve the grounding efficiency and reduce the area occupied by the ground network.
(2) Stable ground resistance. The grounding module itself has a strong ability to absorb moisture and keep the ground around it moist, ensuring that the grounding module can effectively perform its conductive function at the same time, the properties conductive conductive objects in the grounding body are not affected; by seasonal changesers such as dry humidity, high and low temperatures, etc. Therefore, stable ground resistance can be provided.
(3)? Reduce potential counterattacks on the ground. The non-metallic material of the grounding module forms a low resistance area with a relatively smooth change between metal and ground with a huge resistivity difference when a large current strikes, this can reduce the transient potential gradient of the earthing body. and ground wire, and reduce the step voltage and touch voltage to reduce the probability of potential backlash to ground.
After listening to the editor's explanation above about the role of the grounding module. My friends must have a new understanding of grounding modules. In fact, the most important role of grounding modules is in safety installations. Due to the grounding functione security, they are used in anti-interference installations, lightning protection installations and anti-static installations. various factories and communities. Among safety installations such as installations, it can reduce the resistance effect, thereby achieving perfect completion of grounding work and good safety guarantee. That's all for today's explanation of what the grounding module does, I hope. Give everyone a little help.
