Claims
- 1. Assembly for mutually coupling a generator rotor having a superconductive exciter winding and a shaft carrying exciter current leads, and wherein disconnectible electrical, hydraulic and mechanical connections are located in vicinity of the coupling assembly and extend in axial direction of the rotor and the shaft, the coupling assembly comprising, in combination, a pair of couplng halves defining in the interior thereof a hollow chamber gas-tightly sealed against outer atmosphere, the disconnectible connections being located in said hollow chamber and including releasable plug connection halves, respectively comprising mutually telescoping socket-like plug members for a liquid-coolant circulatory system and for the exciter current leads, said plug connection halves being located, respectively, facing the rotor and the shaft, said telescoping socket-like plug members being displaceable in axial direction thereof relative to one another upon insertion thereof in and disconnection thereof from one another and upon thermal expansion thereof, a coaxial channel formed in the shaft, a leak suction chamber surrounding the shaft at the end thereof distant from said coupling halves, said coaxial channel connecting said hollow chamber to said leak suction chamber, and an expansion compensating device disposed in said hollow chamber and vacuum-tightly and axially displaceably connecting to the rotor, the plug connection halves facing the rotor, said expansion compensating device having an end wall, the rotor-facing plug connection halves comprising the respective plug members for the circulatory system and for the exciter current leads and being connected to said end wall of said expansion compensating device.
- 2. Coupling assembly according to claim 8, wherein the coolant circulatory system comprises coolant channels, in the form of coaxial tubes, the coolant channels being mutually connected at a connecting location by said plug members in said hollow chamber defined by said coupling halves, and including sealing rings interposed between said cooling tubes at said connecting location for sealing said tubes yet affording axial displacement thereof.
- 3. Coupling assembly according to claim 2 including evacuated annular channels located between and separating said coaxial coolant tubes so as to thermally insulate said coaxial tubes one from the other.
- 4. Coupling assembly according to claim 1 wherein the exciter current leads comprise hollow conductors extending axially parallel and disposed radially outwardly of the coolant circulatory system, the hollow conductors including said plug members for the exciter current leads.
- 5. Coupling assembly according to claim 4 wherein the exciter current leads in the generator rotor are surrounded by a separate coolant tube and including sealing ring means sealingly interposed between the plug contact connection of the exciter current leads and said separate coolant tube in vicinity of said coupling halves.
