Abstract (en)

[origin: CN202183327U] The utility model relates to an energy storage module for a hydraulic spring energy storage driver, in particular to an energy storage module for the hydraulic spring energy storage driver for operating a high-voltage switch, especially for a high-voltage circuit breaker. The energy storage module is provided with a spring element (51) which serves as an energy storage and fluid used for enabling energy of the spring element (51) to be transmitted to a piston rod for operating the high-voltage switch by utilizing a movable energy storage piston (30), wherein the energy storage piston extends into a shell (1) filled with the fluid and sealed in pressure seal mode, and the shell forms a high-pressure energy storage storing part (13) used for the fluid. The high-pressure energy storage storing part is connected to a hydraulic system of the spring energy storage driver through at least one sub-passage (11 and 12) extending into the high-pressure energy storage storing part and a high-pressure passage (10) linked at the portion of the sub-passage. The energy storage piston seals up a partial area of the sub-passage starting from a certain piston stroke (s).
