Compact converter station
First Claim
1. A converter station for a high-voltage DC connection between two three-phase AC voltage networks, comprising:
- a converter building which has a number of floors, and in which transformer units, converter valves, 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, wherein 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 the air-insulated connecting device, with an air-insulated isolating switch being provided to produce an isolating gap between the DC cable pot head and the smoothing reactor.
