Lightning protection for wind turbines and control systems

摘要

Hub assembly (8) and nacelle (4) of wind turbine including means lightning conducting driving unrayo between the hub (8) and the nacelle (4), the hub (8) mounted for rotation relative to nacelle (4) and estandoadaptado to support the turbine blades (10), the hub (8) a conductor (26) of the hub for conexióncon a turbine blade (10) supported by the hub (8), means lightning conducting track (40) conductive and a terminal (28) which face and are movable relative to each other, one being lapista (40) conductive terminal (28) mounted on the hub (8) and being electrically connected to the conductor (18) of the hub; wherein the other of the track (40) conductive terminal (28) is mounted on the nacelle (4) and elterminal (28) includes a main body terminal (30) which is separate from the track (40) conductive and unaextensión terminal (32, 42) conductive sacrificial including a plurality of conductive members situadoslado side and extending from the main body of the terminal (30) to the track (40).
