Coupling for bus bar system used for transport and distribution of electrical energy between gondola and tower in wind-power plant, has cable for connecting first end of fixed power rail with first end of movable power rails

摘要

The coupling (100) has fixed power rail (200-202) and a moving power rail (300-302) having first and second ends. The conductor rails are electrically connected together. The movable power rail (301,302) is rotatably provided about a rotational axis (D). A cable is provided for connecting the first end of fixed power rail (200) with first end of movable power rails (300). An independent claim is included for wind-power plant.
