The invention relates to an integrated hydraulic operating mechanism. The integrated hydraulic operating mechanism comprises a working cylinder, an energy accumulator and a three-stage integrated electric control valve which is used for controlling a piston rod of the working cylinder to move, wherein the working cylinder is horizontally arranged; the three-stage integrated electric control valveand the energy accumulator are both arranged on the working cylinder; the working cylinder is provided with a connecting end used for being connected to a circuit breaker; the axis of the energy accumulator is parallel to the axis of the working cylinder; an oil circuit interface of the energy accumulator is arranged at one end, far away from the connecting end, of the working cylinder; and the three-stage integrated electric control valve is arranged at one end, far away from the connecting end, of the working cylinder. The oil circuit interface of the electric energy accumulator of the hydraulic operating mechanism is arranged at one end, away from the connecting end, of the working cylinder, and the three-stage integrated electric control valve is arranged at one end, far away from theconnecting end, of the working cylinder, so that the arrangement positions of the working cylinder, the energy accumulator and the three-stage integrated electric control valve are relatively concentrated, the design of an internal oil way is facilitated, and the product cost is reduced.
