Description

Technical field [0001] The invention relates to the electrical field, in particular to a conductive material and its preparation process. Background technique [0002] At present, in electrical facilities, power transmission lines, electrical equipment, facilities, communication equipment and facilities, computer rooms, railways, petrochemicals, high-rise buildings and other places, the grounding of protective grounding and protective grounding devices is reflected in the universal use of ferrous metals or Non-ferrous metals. Because the composition in the soil is very complex, it contains a variety of highly corrosive ions, and the electrical conductivity in the soil is mainly achieved by these highly corrosive ions in the process of ion exchange. During the ion exchange process, the ferrous or non-ferrous metals lose electrons, and the metal material consumes a certain amount of ions, which will corrode the metal grounding body, reducing the effective cross section of the meta...

AI Technical Summary

Problems solved by technology

During the ion exchange process, due to the loss of electrons by ferrous metals or non-ferrous metals, certain ions will be consumed by the metal material, which will corrode the metal grounding body and reduce the effective cross-section of the metal grounding body, which cannot meet the instantaneous high current. When the large current passes through, the grounding body heats up and burns out, making the grounding device lose the function of protection and protection

In addition, during the corrosion process, the metal will generate a new substance, a water-insoluble or slightly water-soluble metal salt. The metal salt is a hard and brittle solid with high resistivity. This layer of solid metal salt is wrapped in the grounding body. outside, so that the metal grounding body cannot be in direct contact with the soil, increasing the resistance of the grounding resistance, which cannot meet the requirements of the grounding resistance value of the grounding device

At present, in order to make the grounding resistance of the grounding device meet the design requirements, a graphite grounding module is used. The graphite grounding module is a kind of non-metallic conductive material, but the graphite grounding modules used so far are all hard and brittle. Under the action of external force, it is very easy to be broken and damaged. It cannot be used as a grounding body and a conductor, but can only be used to increase the surface area of ​​the grounding body. Therefore, it is necessary to design a conductive material and its preparation process that can solve the above problems.
