Study on Dynamic Operation Charateristics of High-voltage Semi-rigid Cable Terminal for EMU
With the EMU number and running time increase in recent years,several ground discharge failures happened on EMU roof caused by insulation failure of high-voltage semi-rigid cable terminal during operation,resulting in a series of accidents.This paper demonstrates the typical accidents of high-voltage semi-rigid cable terminal,tests at 200-300 km/h speed level.The operating vibration characteristic data of high-voltage semi-rigid cable terminal were obtained and the optimal suggestions were proposed by the aspects of design,manufacture,testing and experimental research.
