The present invention relates to an apparatus for preventing the one-sided wear of a trolley wire, which can extend a service life of a trolley wire by preventing the one-sided wear of the trolley wire provided in a lower part of a rigid overhead conductor wire by maintaining an optimum contact state between the rigid overhead conductor wire and a current collector in response to an inclination of the trolley wire of a curved section by preventing torsion between the rigid overhead conductor wire supported by an R-Bar bracket provided in the trolley wire of the curved section and the current collector due to an inclination (Cant) of the inclined curved section; and can prevent an accident such as pantagraph combustion by suppressing arc generation in an expansion element. The apparatus for preventing the one-sided wear of a trolley wire according to the present invention comprises: a hanger clamp for fixing and supporting the rigid overhead conductor wire combining a rigid body and the trolley wire; a bracket head arm provided in a front end of the R-Bar bracket to fixate and support the hanger clamp; an R-Bar bracket which comprises the bracket head arm on the front end thereof, a tail arm on a rear end thereof, and a plurality of bracket insulators at a center; a supporting arm which supports the R-Bar bracket while being fixed and installed on the ground or spatial structure; and an angle adjustment unit which is provided between the supporting arm and an R-Bar and adjusts or fixes an angle of the R-Bar bracket. |
