要約(英語): Localized wear of pantograph contact strips is a significant problem affecting the current-collecting systems in electric railways, because it may cause fusion of the pantograph head, resulting in devastating damage to the overhead contact wire. However, the causes of localized wear of carbon-based contact strips have not been clarified, and thus, effective prevention measures cannot been established. The purpose of this study is to clarify the generation mechanism of localized wear in copper-impregnated carbon-based contact strips. In this study, the actual locally worn strips were analyzed with a micro Raman spectrometer. The sliding wear behavior of contact strips with different degrees of graphitization of the carbon substrate was investigated using a block-on-ring-type wear tester.
