Abstract

The invention discloses a graphite composite grounding protection material and a preparation method thereof. The graphite composite grounding protection material comprises, by volume, the following raw materials including crystalline flake graphite 40%-70%, cement 25%-55%, asphalt 2%-5% and epoxy resin 2%-5%. The graphite composite grounding protection material is applied to metal connecting parts of a metal grounding body and a non-metal grounding body and can effectively protect metal against corrosion, accordingly the stability of a grounding system is greatly improved, the service life of the grounding system is prolonged, and the maintenance cost of a production operation unit is reduced.

Description

technical field [0001] The invention relates to the technical field of lightning protection and grounding of electric power systems, in particular to a graphite composite grounding protection material and a preparation method thereof. Background technique [0002] With the development of the power grid, the construction of various power facilities is increasing year by year, especially in recent years, with the development of UHV transmission projects, large-scale cross-regional transmission lines are becoming wider and wider. Our country has a large area and complex and changeable terrain. There are many dense lightning strike areas in the territory, especially in the southern region. Lightning strike is a relatively serious natural disaster, and the lightning protection grounding of transmission lines is directly related to the safety and stability of the power system. [0003] At present, the main measures taken for lightning shielding of transmission lines include enhan...
