고속철도차량용 주변압기 성능향상을 위한 Mold type기술사양 검토연구

초록

Currently the oil type main transformers are used for all of high speed train in domestic and international railway service. To minimize the weight and size of the transformer comparing with existing them is of benefit to maintenance cost. Old-style way should consider oil leakage problem and explosion safety matter due to the driving vibration. Thus, we tried to apply Mold type main transformer for high speed railway vehicle to make maintenance free, safety, energy savings and high efficiency) in order to improve performance. In this paper we examined the development of key technologies required to classify the main requirements.
