초록

In this paper. the wearing charac teristics of current collecting shoes. interruption phenomena and contact resistances between collecting shoes and conductor rails are estab lished as design parameters for development of the third rail current collector. An experimental analysis for established design parameters is performed as the materials of current collector shoe, contact force, sliding velocity and contact condition (dry/wet condition) between current collectors shoe and conductor rails. As a result of this study. the magnitude of contact force is in proportion to the amount of wear in the collecting shoe, but is in inverse proportion to the interruption and contact resistance between the collecting shoe and the conductor rail. And optimal values of design parameters are pre sented through analyzing the experimental results of the amount of wear, interruption and contact resistance.
