Abstract: The invention relates to a method for examining an electric energy accumulator (31) for a blade angle adjustment drive (14) of a wind turbine (1), comprising an inverter (21), at least one electric motor (20) which is fed by the inverter (21) and the energy accumulator (31). Said electric motor (20) is blocked, the energy accumulator (31) is charged by the blocked electric motor (20) by means of the inverter (21) and the discharging of the thus charged energy accumulator (31) is observed.

Abstract: A pitch system for a wind turbine installation having an electrically driven pitch drive associated with each rotor blade and an electric motor arranged in a rotating part of the wind turbine installation for blade adjustments. A power and control unit is associated with the motor and has line connections for the transmission of power and control data from the power and control unit to the motor and vice versa. The line connections are passed via a first rotating bushing arranged at a connecting point between the rotating part and an axially adjacent stationary region. The pitch system also includes second rotating bushing which operates mechanically and electrically separately from the first rotating bushing and is connectable to the power and control unit and to the motor for maintaining reliable transmission of the power and control data if the first rotating bushing fails.

Abstract: A switchgear cabinet for a wind turbine has a cabinet housing with a ventilation hole defined therein. A fan is disposed in the cabinet housing and supported on the cabinet housing so as to be disposed in front of or in the ventilation hole. A circumferential coaming is disposed on the outer side of the cabinet housing surrounding the ventilation hole. A pan-shaped cover has a closed front and a rim. The cover is disposed over the coaming with the rim extending around the coaming. The cover is spaced from the coaming so as to define at least one air-permeable connection between the fan and the surroundings of the cabinet.
