A Study on Development of Overhead Contact Line System for a Maximum Speed of 400km/h

초록

At a speed of 400km/h, vibration and wave propagation reflection occur severely. These phenomena present negative effects on current collection quality, consequently reducing lifetime of catenary components and safety. For application of the next generation high speed train which has a maximum speed of 400km/h in Korea, a new high speed overhead contact line system appropriate for 430km/h class trains must be developed. Therefore, in this study, the basic specifications of 400km/h class overhead contact line system are proposed. The tension and property of a contact wire and messenger wire, span length, system height and etc. are determined based on the dynamic simulation results between the pantograph and the overhead catenary system. Core catenary components such as a contact wire, tensioning device, steady arm, bracket, clevis termination clamp and etc. are also being developed. In addition, the mounting diagram design software is being developed. The developed system and components will be installed on the Honam high-speed test-bed and evaluated their performance until 2014.
