ABSTRACT:
The invention relates to a rotatable high-current connector 1A, 1B for establishing an electric power supply to movable consumers in closed chambers. The high-current connector includes several rotatable, coaxial pipes 2, 3, 55, 46 for the conduit of a current and a cooling agent. The pipes concerned 2, 3, 55, 46 are at one end provided with flanges 9, 13, 14, 11. Two stationary counter flanges 19, 20 which are insulated with respect to one another are disposed coaxially to these two flanges 9, 13. The electric connection is established via two bundles of strands 17, 18.
In order to provide a passage of two separate circulatory cooling systems across the high-current connector 1A, 1B, the internal borehole 4 and the annular hollow space 5 can be connected to the first circulatory cooling system, on the one side, via screwed fittings 7a, 7b and, on the other side, via flanges 41, 43 having boreholes 34, 40 and they can be connected to the second circulatory cooling system and the two annular gaps 50, 51 via two connecting pieces 8a, 8b, on the one side, and, on the other side, via the connecting flange 33 having boreholes 36, 37.
