Abstract

The invention discloses a graphite grounding module which comprises a graphite module main body which is cast by graphite conductive concrete and a metal steel bar which is connected with the module main body. The graphite conductive concrete material comprises 20 parts of water, 30 to 40 parts of portland cement, 5 to 15 parts of graphite, 10 to 15 parts of sandstone, 2 to 5 parts of humectants, 10 to 25 parts of bentonite, and 5 to 10 parts of electrolyte by weight. Through burying a metal framework in the module and improving present graphite conductive concrete, intensity of the graphite grounding module is enhanced so as to solve a problem of manufacturing a large volume prefabricated module. Improvement of the graphite conductive concrete is reducing graphite content and reinforcing concrete intensity, and through adding little moisture retention material and electrolyte, conductive performance is ensured.

Description

technical field [0001] The invention relates to the field of safety grounding, in particular to a graphite grounding body. Background technique [0002] The grounding device of the power facility plays the role of drainage and dispersal. In order to increase the dispersal effect of the buried underground grounding body, the main body of the graphite module containing graphite conductive concrete is often connected to the metal grounding body, which can increase the surface area of ​​the metal grounding body. Enhance the dissipation capacity of the whole grounding device. [0003] In the prior art, when the grounding module is made into a prefabricated module, the size of the prefabricated module is limited, and it is easy to be broken during transportation and construction. The reason is that after graphite is added to conventional concrete, the strength of concrete is reduced. [0004] ZL02139619 discloses a grounded conductive concrete. This invention has good electrical...
