Grounding module may be relatively unfamiliar to some friends, but it is in the field of industrial manufacturing, chemical production, construction materials, railroad transportation and other fields have applications, can be said to play a large role, a wide range of uses. It is actually a grounding object, but it is a non-metallic materials, why use non-metallic materials to do grounding tools? This is because the stability of non-metallic materials is relatively strong, and conductivity is also good. It can make the grounding process more simple and convenient. So what specifically is it useful for?
Grounding module is a non-metallic material-based grounding body, which consists of conductivity, stability of non-metallic minerals and electrolytic substances, this product effectively solves the problem of metal grounding body in acidic or alkaline soil affinity is poor and easy to surface corrosion of the metal body and the grounding resistance changes, when the soil is too much organic material, easy to form the surface of the metal body is Ink wrapped in the phenomenon, resulting in the conductivity and lagging ability to weaken the situation, increasing the grounding body itself dissipation area, reducing the contact resistance between the grounding body and the soil, with a strong moisture-absorbing and moisturizing capacity, so that the soil resistivity around the vicinity of the reduction in the dielectric constant increases, the interlayer contact resistance decreases, and corrosion resistance is enhanced, and thus obtain a smaller grounding resistance and a longer service life.
Role:
(1)? Reduce contact resistance. The main material of the grounding module and the physical structure of the soil is similar to the soil, can be combined with the soil as a whole, so that the effective contact area of the grounding body and the soil than the metal grounding body many times larger than the effective area of the grounding body to increase the effective dissipation area of the grounding body, greatly reducing the grounding body and the contact resistance of the soil, so it can significantly increase the efficiency of the grounding, reduce the land area occupied by the ground network.
(2)? Stabilize grounding resistance. Grounding module itself has a strong moisture absorption and moisturizing ability, so that the soil around it remains moist, to ensure that the grounding module effectively play the role of conductive; at the same time, the conductive properties of conductive materials in the grounding body is not affected by seasonal changes in dryness and humidity, high and low temperatures, and so can provide stable grounding resistance.
(3)? Reduce ground potential backlash. The non-metallic material of the grounding module makes the huge difference in resistivity between the metal and the soil to form a relatively gentle change of low resistance area, when the large current impact, it can reduce the grounding body, grounding wire transient potential gradient, reduce the step voltage and contact voltage, reduce the probability of ground potential backlash.
Listening to the above editorial about the role of the grounding module description. Friends must have a new understanding of the grounding module, in fact, the biggest role of the grounding module is in the safety facilities, because the role of safety grounding relationship, in all kinds of factories and community anti-interference facilities, lightning facilities and anti-static facilities and other safety facilities, can do to reduce the role of the resistance to achieve the perfect completion of the work of the grounding and security of a good guarantee. About the role of the grounding module explained to you here today, I hope to give you a little help.
