Investigation of Shinkansen Static Changeover Switch Capable of Suppression of Exciting Inrush Current into Transformer on Train

摘要

At substations of Shinkansen, three-phase power received from the utility power system is converted into a pair of single phase power sources with different phases. When a Shinkansen car passes the boundary between two power sources with different phases, the power source for Shinkansen instantly switches from one to the other. Vacuum switches have been used as changeover switches so far.
