300㎞/h 이상 고속대역에서 한국형 고속열차의 집전특성 분석

The Korean High Speed Train(KHST) had been developed and evaluating on the Kyoung-Bu High Speed Line by through "G7-R&D project“. In order to evaluate the function and characteristics of high speed train system, various experimental conditions have been considered and conducted. In this paper, current collection characteristics of KHST between pantograph and catenary system and dynamic behaviors are measured and analysed over 300 to 350㎞/h in running speed of KHST. A measuring system which was developed and installed on the Korean High Speed Train for the performance and mechanical characteristics of the KHST pantograph is used for this trial running test and we proofed that KHST has a remarkable and stable current collection characteristics as it had been designed.
