The invention provides a line arrester gap distance correction method and a gap structure thereof, and relates to the technical field of power transmission and distribution primary equipment of a power system. The method for correcting the gap distance of the line lightning arrester comprises the following specific steps: S1, calculating the series gap distance of the lightning arrester according to the 50% discharge voltage of the positive polarity lightning impulse of the lightning arrester with the gap at the altitude of 1000mm and the gap power frequency withstand voltage when the lightning arrester breaks down, and taking the series gap distance as a reference value for correcting the gap distance at different altitudes; by calculating and testing the series gap distance of the line lightning arrester under atmospheric pressure at different altitudes, a correction method for the series gap distance of the line lightning arrester at different altitudes is obtained, reliable action of the series gap distance of the line lightning arrester under lightning overvoltage at different altitudes is ensured, a line insulator is protected, and the service life of the line lightning arrester is prolonged. Line insulator breakdown or flashover is prevented, and the line trip-out rate is reduced; and meanwhile, the maximum power frequency overvoltage occurring in the system can be tolerated.
