The invention discloses a wear leveling pressure regulator, a carbon brush switching method and a switching distinguishing method. The wear leveling pressure regulator is provided with a plurality of brackets for mounting carbon brushes. The brackets are mounted in placement grooves of a fixed seat. The fixed seat is mounted on a lower rotary shaft provided with an inserting groove. An upper rotary shaft is provided with a pressing rod and a supporting rod; the pressing rod is used for pressing the brackets where the carbon brushes needing to be used are arranged; the supporting rod is used for supporting the upper rotary shaft to prevent the brackets from being excessively pressed by the pressing rod. The wear leveling pressure regulator has the beneficial effects of realizing leveled wearing and prolonging service life by replacing the used carbon brush; furthermore, the wear leveling pressure regulator also has the beneficial effects that the plurality of carbon brushes are selected according to the size o
