Zusammenfassung:A multi-dimensional analysis method for a whole-line lightning shielding failure tripping risk of a power transmission line, comprising: first collecting data of a thunderstorm day, tower size, terrain proportion, altitude and insulation configuration of a power transmission line that requires lightning shielding failure tripping risk analysis; and calculating in sequence strike distance and exposure distance, and correcting the line lightning resistance level of an altitude factor and a lightning shielding failure risk of a single-base tower. Lightning shielding failure characteristics when nominal height, lightning day, terrain and the like are different are researched on the basis of a calculation model, and a weak link in the whole line may be identified; and a representative combination condition is selected to calculate a typical tower lightning shielding failure tripping risk, and on the basis of a same-region whole-line terrain proportion and a tower use condition, a weight coefficient is extracted to
