Temperature Characteristics of Main Transformer for KHST using Sensors

초록

Railway is configured with rolling stock, tunnel, bridge such as track architecture, power supply facilities, signal system. The importance of security is widely known since it is directly related with life damage. Recently, adopting railway security is required with railway car high speed and high performance tendency. For realizing this design, manufacturing and test and evaluation of each component shall be performed synthetically. Especially, It shall be essentially performed that static and dynamic test for each component which is designed and manufactured and safety evaluation on structure through total integration test of each components. In this study, temperature sensors were adhered to transformer that is used in KHST(Korean High-Speed-Train) to verify variation of temperature characteristics about transformer synthetically and efficiently. In the case that temperature of transformer exceeds reference temperature for running of KHST, overheating of transformer may cause a fatal accident of vehicle. Therefore, after on-line measuring system was constructed in vehicle, oil temperature and tank temperature were measured on real-time.
