Abstract: A switchgear assembly for a wind turbine comprises an electric switchgear and a support structure supporting the electric switchgear, wherein the support structure comprises a damping device for damping mechanical impacts due to vibrations during operation of mechanical parts of the wind turbine. The switchgear assembly can be used in an offshore wind turbine.

Abstract: A fast earthing switch device for HV applications which includes a gas-tight casing, a movable contact connectable to and unconnectable from a fixed contact. The movable contact is linearly movable between an open position and a closed position. The device further includes an operating mechanism for the movable contact and is characterized in that the operating mechanism includes an actuating spring actuating a closing operation of the movable contact from the open position to the closed position, at least a driving lever mounted on an operating shaft actuating an opening operation of the movable contact from the closed position to the open position, the driving lever also partially reloading the actuating spring during the opening operation, the operating mechanism further includes coupling means operatively coupling the driving lever to the movable contact.

Abstract: A fast earthing switch device for HV applications which includes a gas-tight casing, a movable contact connectable to and unconnectable from a fixed contact. The movable contact is linearly movable between an open position in which it is spaced apart from the fixed contact and a closed position in which it is connected to the fixed contact and vice versa. The device further includes an operating mechanism for the movable contact and is characterized in that the operating mechanism includes an actuating spring actuating a closing operation of the movable contact from the open position to the closed position, at least a driving lever mounted on an operating shaft actuating an opening operation of the movable contact from the closed position to the open position, the driving lever also partially reloading the actuating spring during the opening operation, the operating mechanism further includes coupling means operatively coupling the driving lever to the movable contact.

Abstract: An exemplary HV switching device includes a casing having at least a first fixed contact and a second fixed contact that are spaced apart from each other and can be connected to two corresponding power terminals. A first movable contact and a second movable contact are spaced apart from each other and actuated for coupling the first fixed contact and the second fixed contact, respectively. At least one of the first fixed contact and first movable contact has a shape for coupling the first movable contact to the first fixed contact in at least a first coupling position and a second coupling position which are spaced apart, and at least one of the second fixed contact and second movable contact has a shape for coupling the second movable contact to the second fixed contact in at least a third coupling position and a fourth coupling position which are spaced apart.
