RUNNING CHARACTERISTICS FOR ON-LINE TEST OF RAILWAY VEHICLE

초록

The traction system is composed of motor block and traction motor. They are important electric devices on KTX. Motor block controls speed and acceleration by changing voltage supplied into traction motor. The changed voltage used for the input power of traction motor in the bogie frame generates the driving power. In this paper, we build the on-line measuring system to verify the performance and function of the traction system used in KTX. The data recorded by running and braking measurement system is analyzed and evaluated. Here, the signal control system and data recording equipment are described and the structure and principle of the main circuit system is simply explained."
