Abstract

A storage module for a hydraulic stored-energy spring mechanism for operating a high-voltage switch, for example a high-voltage circuit breaker, having a spring element which acts to store energy and having a fluid for transmitting the energy of the spring element, by a moving storage piston, to a piston rod for operating the high-voltage switch, wherein the storage piston projects into the housing which is filled with fluid and the housing forms a pressurized storage reservoir for the fluid. The pressurized storage reservoir is connected to a hydraulic system of the stored-energy spring mechanism by at least one channel element which projects into the pressurized storage reservoir and a pressurized channel which is connected to the channel element. The storage piston closes a subregion of the channel element starting from a specific piston stroke “s”.
