WIND TURBINE AND METHOD OF CONSTRUCTION OF A WIND TURBINE

摘要

The invention concerns a wind turbine (1', 1'') with a nacelle (5) and a rotor (8), the rotor (8) comprising a number of blades (10) and a hub (7), the nacelle (5) and the hub (7) being connected with each other in an interface region (17), the wind turbine further comprising a transport system (20) for transporting hydraulic and/or pneumatic fluid from the nacelle (5) into the hub (7). The transport system (20) comprises a rotary unit (13) as a connection through which the fluid passes and a part of which rotates in operation together with the hub (7) which rotary unit (13) is positioned in the hub (7) at a position distanced from the interface region (17) facing away from the nacelle (5), the transport system (20) further comprising a pipe system (11) leading from the interface region (17) into the hub to the rotary unit (13) and being fixed in its position. The invention also concerns a method of construction of such wind turbine (1', 1'').
