Evaluation Plan of Overhead Catenary System for a Maximum Speed of 400km/h

초록

In electric railway, an overhead catenary system is the one of the main subjects for increasing speed, because a vibration and etc. by a pantograph occur severely. For application of the next generation high speed train, called HEMU, in Korea, we developed and constructed a new high-speed overhead line system for a maximum speed of 400km/h in Honam High-speed line. In this study, an overview of Evaluation Plan for current collection performance test and method for the system is presented. The tests to measure current collection performance will be performed in track-sides and on-board of a train. Through the tests, abnormal current collection dynamic behavior between pantograph and contact wire can be detected.
