Abstract
Device for transmitting rotary motion in a diverter switch comprising a motion-transmitting member for transforming an alternating rotary motion of a drive shaft into a unidirected rotary motion of a driven body driven about driven shaft. The motion-transmitting member includes an intermediate body rotatable about an intermediate shaft. A mechanical energy accumulation member is connected to the driven body. The motion-transmitting member for transforming the alternating rotary motion of the drive shaft into a unidirected rotary motion of the driven shaft includes an intermediate motion member connected to a crank mechanism. The motion member includes an engagement mechanism for transforming the linear motion into a unidirected rotary motion of the intermediate shaft via drive members.

A device for transmitting rotary motion in a diverter switch, said device comprising:
- a motion-transmitting member for transforming an alternating rotary motion of a drive shaft into a unidirected rotary motion of a body driven about driven shaft, wherein the motion-transmitting member comprises
- an intermediate body that is rotatable about an intermediate shaft,
- a mechanical energy accumulation member connected to the driven body, said energy accumulation member being adapted to receive energy from the intermediate shaft, and
- a mechanical energy transmitting member configured to transmit the mechanical energy accumulated in the energy accumulation member to the driven body,
- an intermediate motion member, connected to the drive shaft with a crank mechanism, for transforming the alternating rotary motion into an alternating linear motion, said intermediate motion member comprising engagement member for transforming the linear motion into a unidirected rotary motion of the intermediate shaft via drive members, and wherein the motion member is designed to exhibit an overtravel in relation to the transmitted rotary motion.
A method for controlling a transformer, a reactor or a capacitor by transmitting rotary motion in a diverter switch, the method comprising:
- transforming an alternating rotary motion of a drive shaft into a unidirected rotary motion of a body driven about driven shaft utilizing a motion-transmitting member, wherein the motion-transmitting member comprises
- an intermediate body that is rotatable about an intermediate shaft,
- a mechanical energy accumulation member connected to the driven body, said energy accumulation member being adapted to receive energy from the intermediate shaft, and
