The invention relates to an arc-shaped high-voltage electrode capable of generating a simulated uplink precursor, belonging to the technical field of research of lightning protection. The arc-shaped high-voltage electrode is additionally provided with an arc-shaped voltage balancing net and a spherical electrode on the basis of the prior art, wherein the spherical electrode is fixed on one end ofa central support rod; a plane voltage balancing net of the arc-shaped high-voltage electrode is flatly paved on the lower surface of a tabulate support frame, and the arc-shaped voltage balancing net is flatly paved on the lower surface of an arc-shaped support frame. The arc-shaped high-voltage electrode capable of generating the simulated uplink precursor can meet the requirement for the influence of a downlink precursor on an object positioned at a low-voltage side under natural lightning stroke and has multiple advantages of light weight of integral equipment, low cost, long service life, and the like.
