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 (2.58) 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° of the gear (232) meshing with this gear segment (236). The spiral spring (216) is thereby loaded via the loading lever (230). When the three-way valve (256) is changed over, the cylinder- piston unit (214) is hydraulically connected to the low- pressure reservoir (266), as a result of which the gear segment (236) is pivoted back under the force of the restoring spring (250), and the piston-cylinder unit (214) is moved back into the inoperative position. Unloading of the spiral spring (216) is prevented by the backstop (232), and the coupling between the loading lever (230) and the gear (232) is neutralized by a free- wheel. It is possible to drive the cylinder-piston unit (214) with thin-bodied hydraulic oil, which permits reliable working in a Wide temperature range.
