SUBSTATION DEVICE, RAILWAY POWER SUPPLY SYSTEM, AND METHOD FOR FEEDING AT LEAST ONE SINGLE-PHASE SUPPLY LINE

摘要

The invention relates to a substation device (12, 12a, 19) for feeding at least some sections of at least one single-phase supply line (3), in particular a contact line of a route (8), from at least one three-phase power supply grid (6), comprising at least one transformer (13) which is designed to be connectable to at least two phases (25) of the power supply grid (6) on the primary side and to the supply line (3) on the secondary side. The aim of the invention is to improve known railway power supply systems. According to the invention, this is achieved in that the at least one transformer (13) is designed to adjust a phase position of at least one secondary-side voltage. The invention further relates to a railway power supply system and to a method for feeding at least one single-phase supply line (3).
