Abstract: The stored-spring-energy actuator mechanism (210) for the high-voltage circuit breaker (218) has a spiral spring (216) which can be loaded by means of the loading device (212). The high-voltage circuit breaker (218) can be switched on once and off once with the energy stored in the loaded spiral spring (216). The energy stored in the fluid-pressure accumulator (258) is sufficiently great to charge the spiral spring (216) at least once. The working-stroke movement of the piston rod (242) in arrow direction (A) is transformed via the gear segment (236) into a rotation through 360.degree. of the gear (232) meshing with this gear segment (236). The spiral spring (216) is thereby loaded via the loading lever (230).

Abstract: Two disks per vacuum switch tube are mounted on a drive shaft, the disks having grooves running around the drive shaft and open in relation to one another. In the grooves of two of these disks, a cylindrical follower is guided, the movement of which is transmitted via a link to a swivel lever and to a movable switch contact. The drive shaft is driven, supported via a releasable support member in the switch-on and in the switch-off position, in a clockwise direction by the spiral spring in order to switch off or switch on the power switch. The follower is restrictedly guided in the grooves of the disks, whereby the position of the movable switch contact is obliged to correspond to the corresponding rotation position of the drive shaft.

Abstract: In a stored-spring-energy type actuator mechanism for a high-voltage circuit breaker, energy is stored in a spiral spring in order to switch on the circuit breaker and also to load a switch-off spring of the circuit breaker. To store sufficient energy for more than one switch-on operation, a fluid-pressure accumulator is provided in which sufficient energy is stored to wind up the spiral ring at least one additional time through a fluid-pressure motor. Between the pressure accumulator and the motor is a control valve which opens when the spiral spring is partly unloaded, causing the hydraulic motor to rewind the spring.
