Technical review of on-board mold transformer for high-speed train

초록

Main transformer is a power source for driving the traction motor is installed in the lower space of the vehicle, an auxiliary power supply and power propulsion of the train through the converter, an inverter I have supplied. It is intended technical study for development dry it is possible to prevent leakage is a drawback of the inflow Transformer which is applied to an electric railway vehicle, has the advantage not require maintenance (Mold Type) transformer. Railway vehicle Dry (Mold Type) transformer, so the transformer is a new concept that can solve the drawbacks of the inflow Transformer conventional, by developing it, is mounted on the train existing vehicle. It may improve reliability. In this study, we have proposed a specification and basic design requirements for product development through the technical studies for the application for rail vehicles of dry (Mold Type) transformer.
