고속선 및 기존선에서 한국형 고속열차의 집전특성 분석

The pantograph for Korean High Speed Train was developed and had been evaluating by through "G7-R&D project" for home grown high speed train technology. In this paper, from the point of view in mechanical aspect, comparison study on the current collection characteristics between the KHST pantograph and contact wire in catenary system on the High-Speed Line and Ho-Nam/Kyoung-Bu conventional lines is conducted. A measuring system for the performance and mechanical characteristics of the KHST pantograph is used for this study, which was developed and installed on the Proto-type Korean High Speed Train, and physical characteristics were measured while the KHST runs on the High-Speed Line and conventional lines. Through this study, remarkable variations of characteristics which can affect to a current collection quality of high-speed train are found and analyzed from measured mean contact forces in both tracks.
