ABSTRACT:
In order to provide a converter station for a high-voltage DC connection between two three-phase AC voltage networks, having a converter building which has a number of floors, and in which transformer units, converter devices, filter units, a gas-insulated switchgear assembly with feeder units, at least one cooling system, a DC cable pot head for electrical connection of a high-voltage cable carrying direct current, a smoothing reactor and gas-insulated busbars for electrical connection of these components are arranged, while maintaining its compact design and the arrangement of its components in a closed building, whose cost is low and which has a physically simple design, the invention proposes that the DC cable pot head and the smoothing reactor are arranged on the same floor as the converter valves and are electrically connected to one another via an air-insulated connecting device, with an air-insulated isolating switch being provided in order to produce an isolating gap between the DC cable pot head and the smoothing reactor.
