The invention relates to an electric rotation type high-voltage test grounding electrode. The electric rotation type high-voltage test grounding electrode comprises a base, a left vertical plate, a right vertical plate, a guiding plate and a grounding electrode body; the grounding electrode body comprises a grounding electrode rod body, a limiting plate arranged at the upper end of the grounding electrode rod body, an electric connector arranged at the upper end of the limiting plate, a drill body arranged at the lower end of the grounding electrode rod body, and a wiring plate arranged on thefront side surface of the limiting plate; the base, the left vertical plate, the right vertical plate, the guiding plate and the grounding electrode body are all aluminum alloy parts; and the aluminum alloy is prepared from the following components based on mass percentages: 2.0-3.2% of Mg, 3.5-4.5% of Si, 0.2-0.3% of Mn, 0.1-0.2% of Cr, 0.18-0.25% of Zr, 0.35-0.40% of Ti, 0.15-0.3% of Yb and the balance of Al and impurities less than or equal to 0.05%. Specific to the problems of time consumption and labor consumption in test grounding electrode installation, easy corrosion and high mass, the electric rotation type high-voltage test grounding electrode is provided, and the provided test grounding electrode is not only high in intensity, excellent in corrosion resistance and light in weight, but also capable of automatically drilling into the ground to realize the grounding operation.
