AIR-GAP SECURE SYSTEM FOR A WIND TURBINE

摘要

Disclosed is a wind turbine, which comprises a rotatable structure being coupled to a hub of the wind turbine and to a generator rotor comprising a brake disc, a stationary structure being coupled to a generator stator and comprising a stator frame and a safety bearing element. The rotatable structure is rotatably coupled to the stationary structure, wherein the stator frame (102) comprises a brake mounting section to which a calliper brake is mountable such that the brake disc is breakable by the mounted calliper brake. The safety bearing element is mounted to the brake mounting section such that the brake disc is in slidable contact with the safety bearing element if a distance between the brake mounting section and the brake disc is reduced below a predetermined reference value.
