일반철도선로 안정성 향상을 위한 전철설비의 특성에 관한 연구

Abstract

These days, the cautions and worries about safety has emerged as a major interest in the whole society, and it definitely includes the field of the rail way system which a few millions of people are using a day. Among various systems that the railway system consists of, the electric power facilities that supplies trains with electricity play a vital role for retaining the stable rail service. Therefore, it is very demanding to develop the techniques to maintain and repair the facilities by correctly predicting their residual life. These techniques should be based on the analysis of the effects from the factors of regional and seasonal circumstances in Korea, and the current state of the rail way maintenance and material supply state, to propose the better direction to improve safety and develop the method of maintenance and repair of the rail way system. This research aims to investigate the components of the railway system and the role of PDS(power disconnecting switch), which is one of the most vital facilities in the railway system, examining its general characteristics. Then, it will analyze the main causes of the malfunction in PDS, proposing possible measures to prevent the breakdowns and disorders from it.
