Abstract

The invention discloses an environment-friendly aluminum copper rare earth alloy vertical earthing electrode and a preparation method thereof. The earthing electrode comprises an earthing electrode body made of an environment-friendly aluminum copper rare earth alloy material and an earthing electrode lead-in head made of an aluminum alloy material. The earthing electrode lead-in head is arranged at the lower end of the earthing electrode body. The preparation method comprises the following steps: casting an alloy ingot and carrying out hot extrusion moulding to prepare the earthing electrode body; carrying out shot peening and preoxidation composite treatment on the earthing electrode body; casting the earthing electrode lead-in head; and combining the earthing electrode body and the earthing electrode lead-in head. By optimizing the structure and material of the vertical earthing electrode, the vertical grounding electrode has good dispersion ability, grounding conductivity and soil corrosion resistance, and meanwhile, has the advantages of convenient construction and easy soil implantation and the like.

Description

technical field [0001] The invention relates to an environment-friendly aluminum-copper rare-earth alloy vertical grounding electrode and a preparation method thereof, belonging to the technical field of electric power grounding. Background technique [0002] The grounding grid is an important facility to ensure the safety of power system equipment and people. The grounding materials currently used are mainly galvanized steel and pure copper. The corrosion rate of galvanized steel in the soil is high, and the operating life is short, which cannot guarantee the safe operation of the power grid. Pure copper has good corrosion resistance and electrical conductivity in soil, but it will cause soil pollution when used in large quantities in grounding grids, and copper resources in my country are in short supply and the price is high. [0003] The environment-friendly aluminum-copper rare-earth alloy grounding material is a new type of grounding material. It uses aluminum as the...
