摘要： 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.
