아크방전을 이용한 전기철도용 비접촉 집전시스템 적용방안 검토

초록

The power supply system in railway has been developed for high speed train such as wheel type and MAGLEV. The conventional power collection with contact between pantograph and contact wire was disadvantage for increase the speed. Also, it’s system had problems with wear of contact points, noise generation, arc discharge generation due to incomplete contact. Therefore the contactless power transfer system was proposed to solve these problems in transportation system. There were inductive coupling, capacitive coupling, electromagnetic wave transmission with resonance coupling and plasma bridge between vehicle and wire in contactless power transfer method. This paper is presented about current collection using arc discharge between power line and collector shoe in railway.
