Power sub-station a case for supplying two sections of road network

摘要

The present invention relates to a power sub-station (4) for supplying a first and a second section of road (1, 2) of a case of network with electrical energy from a three-phase mains power supply (8) with three phases via a first and a second transformer (5, 6) - with primary and secondary sides (5 ', 5 ", 6', 6"), dollar a - wherein the first and the second section (1, 2) are electrically insulated from one another, dollar a - wherein the primary side (5 ') of the first transformer (5) to the first and the second phase of the three-phase system (8) and the primary side (6') of the second transformer (6) to the second and the third phase of the three-phase current line (8) can be connected, dollar a - wherein the secondary side (5 ") of the first transformer (5) to the first section (1) and the secondary side (6") of the second transformer (6) to the second section of road (2) can be connected, dollar a - wherein the secondary sides (5 ", 6") of the transformers (5, 6) of a common ground point (14) have. Dollars a to the reduction or elimination of an asymmetrical loading of the three-phase current line (8), it is proposed to the first transformer (5) a capacitive and to the second transformer (6) an inductive load (16, 17) connected.
