Abstract
Official abstract text for this publication.
A wind turbine having a nacelle with a stationary region and a rotor, at least one blocking unit for blocking the rotor, and an access control system is provided. The access control system controls a locking of at least one access door to at least one closed-off region in the wind turbine depending on a blocking of the rotor by means of the least one blocking unit. The access control system has a key transfer system and a hydraulic control unit for controlling the blocking unit. The key transfer system has a hydraulic key unit for preventing an unintentional activation of the hydraulic unit and an access door key unit for locking or unlocking the access door. The key transfer system has at least one first and second key, the hydraulic control unit being locked or unlocked by means of the first key, and the access door key unit being locked or unlocked by means of the second key, and the key transfer system also having a fan key unit for activating or deactivating a fan, the first key of the hydraulic key unit being used to lock and unlock the fan key unit and a fan key being used as a second key for locking or unlocking the access door key unit.
