connecting lever for the buffer, reduce the impact to switch on of moving contact process for the buffer, and by It is more than the aperture of the first radial direction oil hole in the aperture of the second radial direction oil hole, so can further improve the through-flow energy of hydraulic oil Power, the further damping reducing hydraulic oil, at the end of closing a floodgate, Sub-gate release device and the spacing cooperation of separating brake roller, So that tripping spring to be held in energy storage state.When needing dynamic and static contact separating brake, Sub-gate release device releases to separating brake roller Spacing, tripping spring drives integrated connecting lever to rotate, and output toggle arm drives moving contact towards away from corresponding stationary contact also by output pull bar The motion of head direction, integrated connecting lever drives bearing pin to move towards hinge hole head end, because hinge hole is an elongated hole, therefore separating brake it Just, piston rod does not move forward, and buffer does not produce damping action it is ensured that the separating brake of moving contact is initially fast to integrated connecting lever Degree, moves to the head end of hinge hole with rear pin shaft, and piston rod band piston moves, and is closed on piston cap by hydraulic oil effect piston One end is close to the corresponding end of piston cap, and the axial oilhole on piston is blocked by piston cap, in the first radial direction oil hole institute on piston The hydraulic oil of side piston can only be flowed to by the first radial direction oil hole, annular gap and this circuit of the second radial direction oil hole Rear side, the circulation area of hydraulic oil is little, the damping force of hydraulic oil big it is ensured that the damping to integrated connecting lever for the buffer, and Aperture due to the first radial direction oil hole is less than the aperture of the second radial direction oil hole, further increased the damping force of hydraulic oil, from And realize different dampings during breaking-closing operating.Piston is by the inside and outside annular
