Wind turbine with sealed off stator chamber

摘要

A wind turbine having a wind turbine tower with a nacelle; a wind turbine rotor hub with at least one rotatably mounted wind turbine blade; a shaft coupled to the wind turbine rotor hub and a generator. The generator has a rotor having at least one superconducting rotor coil arranged rotatably relative to a stator having at least one stator coil. The rotor is arranged in a rotor housing and the stator is arranged in a stator housing, the housings being separated by a rotor-stator gap. The stator housing has a stator inner shell and a stator outer shell connected together by at least one stator housing end plate. The stator inner shell has a first inner shell element attached to a stator iron that is connected to a second inner shell element. A pressure plate is attached to the second inner shell element and the stator outer shell.

1. A wind turbine comprising:
a wind turbine tower a nacelle provided on the wind turbine tower a wind turbine rotor hub rotatably mounted at the nacelle, the wind turbine rotor hub having at least one wind turbine blade mounted thereon a shaft coupled to the wind turbine rotor hub, and a generator coupled to the shaft, which generator comprises a rotor arranged rotatably in relation to a stator, which rotor comprises at least one superconducting rotor coil in a rotor chamber encapsulated by a rotor housing, and which stator comprises at least one stator coil of a conducting material, where the stator coil is in a stator chamber encapsulated by a stator housing; the superconducting rotor coil and the stator coil being arranged to have interacting magnetic fields for inducing a current in the stator coil when the rotor is rotated, and where there is a rotor-stator gap between the rotor housing and the stator housing wherein the stator housing comprises a stator inner shell facing the rotor housing, wherein the stator inner shell comprises at least a first inner shell element which is at least attached to at least one wedge in a stator iron arranged in the stator chamber by an adhesive having strong adhesion properties to the materials of the wedges and to the first inner shell element.
