Abstract: The present invention relates to a rope-driven transmission for a wind turbine. The transmission comprises an input rotary member for being operatively connected to a rotor of a wind turbine and in rotational connection with at least one secondary shaft which is arranged in parallel with the rotational axis of said input rotary member, wherein said secondary shaft is adapted for operative connection with an output member of at least one electrical generator, wherein said rotational connection between said input rotary member and said at least one secondary shaft is provided by a rope, the course of said rope defining a rope path, and wherein said rope path includes a plurality of turns around said input rotary member and said secondary shaft. The transmission facilitates an easy monitoring and maintenance of the transmission. The invention further relates to a method of maintaining the transmission by replacing the rope. The invention further relates to a wind turbine generator comprising the transmission.

Abstract: The invention provides a wind turbine comprising a nacelle, a rotor comprising at least one blade attached to a hub, and an electrical supply structure for supplying electrical power from the nacelle to the rotor. The rotor is rotatably connected to the nacelle about an axis of rotation. The supply structure comprises a switch which has a connected mode in which the nacelle and the rotor are electrically connected, and a disconnected mode in which the nacelle and the rotor are electrically disconnected. Furthermore, the switch is adapted to change from the disconnected mode to the connected mode when the rotor does not rotate.
