The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment 1 of the hydraulic pressure spring operating mechanism of the utility model, as shown in Figures 1 to 4, hydraulic spring grease cup actuating
Mechanism includes piston cylinder 8, the telescoping cylinder being fixedly connected on piston cylinder 85 and the multiple groups disc spring piece 3 being sleeved on piston cylinder 8,
Certainly, other kinds of spring can also be used in disc spring in other embodiments.There is in piston cylinder 8 piston rod 6, piston rod 6 with
Moving contact is connected as moving contact and provides energy.Because the moving contact in the arc-chutes in breaker is linear motion, so piston cylinder 8
On piston rod 6 need to keep linear motion state.In order to ensure 8 piston rod 6 of piston cylinder keeps linear motion state, piston cylinder 8
Upper end is equipped with guide plate 7, guide plate 7 and 6 shaft hole matching of piston rod, plays the role of to 6 guide and limit of piston rod, and this
Guide plate 7 in embodiment is fixed with piston cylinder 8 by screw.There are three telescoping cylinders for the fixed installation of 8 upper end outside wall surface of piston cylinder
5, telescoping cylinder 5 is hydraulic cylinder, and downward, the hydraulic fluid chamber of telescoping cylinder 5 passes through connecting hole and oil to the telescopic end of three telescoping cylinders 5
Pipe connection.Three telescoping cylinders 5 in the present embodiment are uniformly distributed in 8 outer peripheral surface of piston cylinder, certainly telescoping cylinder 5 in other embodiments
It can be other numbers other than three, telescoping cylinder 5 can also be otherwise fixedly mounted on 8 outer peripheral surface of piston cylinder.It is flexible
The pressing plate 10 for compressing disc spring piece 3 and with the press cooperation of telescoping cylinder 5, pressure are set on 8 outer peripheral surface of piston cylinder of 5 downside of cylinder
Guide ring 9 is installed, the purpose of setting guide ring 9 is to make pressing plate 10 by fixed-direction in work between plate 10 and piston cylinder 8
It is slided in 8 outside wall surface of plug cylinder.There is the location hole 101 cooperated with 5 telescopic rod top end of telescoping cylinder on pressing plate 10, location hole is set
101 purpose is that one side location hole 101 can play the role of limiting 5 telescopic rod of telescoping cylinder, is on the other hand remarkably improved
The assembly efficiency of hydraulic pressure spring operating mechanism in the present embodiment.
It is applied to cut-off high-tension circuit-breaker by hydraulic pressure spring operating mechanism in this present embodiment, therefore hydraulic spring grease cup actuating
Mechanism need to provide higher actuating force for moving contact, and in other words, the spring in hydraulic pressure spring operating mechanism need to have longer stroke.In order to
The length of piston cylinder 8 is saved, 8 lower end of piston cylinder in the present embodiment has been connected through a screw thread extended segment 4, in other embodiments
Extended segment 4 can also be fixed on piston cylinder 8 by way of grafting.Extended segment in the present embodiment is tubular structure, extended segment 4
Diameter it is identical as 8 diameter of piston cylinder and be in the same plane the outside wall surface of extended segment 4 and the outside wall surface of piston cylinder 8, this
The purpose of sample design is on the one hand to be sleeved on piston cylinder 8 convenient for multiple groups disc spring piece 3, on the other hand facilitates multiple groups disc spring
Piece 3 is adjacent on piston cylinder 8 and extended segment 4, to facilitate pressing plate 10 and the guiding assembly of extended segment 4.The upper end of disc spring piece with
Pressing plate is held out against, and the lower end of extended segment 4 is equipped on the length direction of extended segment to the Stop structure of disc spring piece lower end block.This reality
Applying the Stop structure in example includes the support plate 2 radially extended along extended segment, and support plate also can be used in other embodiments
The other structures such as support ring.Multiple groups spring leaf is pressed in support plate 2, and snap ring 1 is equipped on the downside of support plate 2, and snap ring 1 can will prop up
Fagging 2 is fixed on extended segment 4, and certainly, in other embodiments, other clamping structures such as bail can also be used in snap ring.
Hydraulic pressure spring operating mechanism working principle in the present embodiment is, when work, operation of oil pump drives hydraulic oil to enter
Telescoping cylinder 5,5 telescopic end of telescoping cylinder drive downlink by hydraulic oil, compress multiple groups disc spring piece 3, disc spring piece 3 gradually reduces, and works as movement
Oil pump is closed when to setting height, and telescoping cylinder 5 is in state of pressure keeping, and the elastic force of disc spring piece 3 acts on telescoping cylinder 5 at this time,
It is exactly that the active force of disc spring piece 3 acts on the hydraulic oil in telescoping cylinder 5,3 amount of force of disc spring piece determines liquid in telescoping cylinder 5
The pressure size of pressure oil.When hydraulic pressure spring operating mechanism is connected to point or after reclosing command, the oil circuit deflecting at once in system is stretched
Hydraulic oil in cylinder 5 is extruded at once under the action of disc spring 3 elastic force of piece, and the combined floodgate or closing position completed needed for flowing to.
When separating brake, hydraulic oil enters the epicoele of piston cylinder 8 under the control of reversal valve, pushes 6 downlink of piston rod, completes separating brake movement.
When combined floodgate, hydraulic oil enters the cavity of resorption of piston cylinder 8 under the control of reversal valve, and piston rod 6 is pushed to move up, and completes feed motion.
When needing to change the energy storage pressure of spring operating mechanism, extended segment 4 is removed, and the extended segment for other length that change the outfit, if needed
Increase energy storage pressure, then needs the longer extended segment of length that changes the outfit, and increase accordingly the quantity of disc spring piece；If necessary to reduce storage
Energy pressure, then need the shorter extended segment of length that changes the outfit, and subtract the quantity of corresponding disc spring piece.
