Abstract
A hydraulic device for operating at least one linearly movable component, especially a movable contact piece of a medium-voltage or high-voltage power circuit breaker, includes a piston-cylinder configuration being assigned to the at least one component. A high-pressure reservoir supplies a hydraulic fluid at high pressure to the piston-cylinder configuration. A low-pressure reservoir is provided for the hydraulic fluid. A pump conveys the hydraulic fluid from the low-pressure reservoir to the high-pressure reservoir. A central distribution device is connected to the at least one component and has at least one line for the hydraulic fluid at high pressure and at least one line for the hydraulic fluid at low pressure.
