Abstract
The utility model discloses an opening limiting closing buffer structure for a load switch. The opening limiting closing buffer structure comprises a connecting lever, wherein a central portion of the connecting lever is connected with an operation rotation shaft and can be driven by the operation rotation shaft to swing, a front end and a back end of the connecting lever are respectively provided with a roller, a framework at one side of the operation rotation shaft is respectively provided with a limiting device and an oil buffer which are opposite to the two rollers, and the connecting lever is driven by the operation rotation shaft to enable the two rollers to selectively press against the limiting device and the oil buffer. Through the opening limiting closing buffer structure, when the load switch is closed, over-stroke of an operation mechanism of the load switch which is caused by inertia force and relatively large force of a closing spring and can cause collision between the connection lever and the load switch is avoided, so damage to a composite switch body is avoided; when the load switch is opened, a rebound elimination effect is realized through the oil buffer, and thereby closing limiting and opening rebound elimination of the load switch during operation are realized, and requirements for mechanical operation characteristics of the load switch are realized.
Description
Technical field
The utility model relates to a kind of spacing combined floodgate buffer structure of separating brake of on-load switch, belongs to mesohigh power transmission and distribution technical field.
Background technology
In the electrical power distribution system switchgear, because the operating mechanism segment space inside of on-load switch is very narrow and small, need on the body of on-load switch transmission, increase position-limit mechanism and buffer gear, existing position-limit mechanism and buffer gear arrange unreasonable, complex structure, operate inconvenience, very flexible on the one hand, due to the poor reliability of operation, easily damage load switch body on the other hand.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can improves operating reliability, avoids the spacing combined floodgate buffer structure of separating brake of the impaired on-load switch of on-load switch.
In order to solve the problems of the technologies described above, the spacing combined floodgate buffer structure of the separating brake of on-load switch of the present utility model, comprise a connecting lever, the middle part of connecting lever is connected to also can be at the drive lower swing of operation rotating shaft in the operation rotating shaft, the rear and front end of connecting lever is respectively arranged with a roller, on the framework of described operation rotating shaft one side, be respectively arranged with and two stopping means and oil bumpers that the roller position is relative, connecting lever can make two rollers optionally be pressed on stopping means and oil bumper under the drive of operation rotating shaft.
Described stopping means comprises a cushion block, and the front of cushion block is relative with the roller position of connecting lever front end, and the cushion block back side is connected with a screw rod, and described cushion block is fixedly connected on framework by screw rod.
Be provided with bolster between described cushion block and framework.
Described bolster is the Cowhells packing ring.
After adopting above-mentioned structure, due to arrange with two stopping means and oil bumpers that the roller position is relative, when on-load switch closes a floodgate, by the bolster on stopping means, cushioned, make mechanism's stop motion, the operating mechanism that prevents on-load switch is because the strength of inertia force and switching-in spring caused more greatly stroke, cause the body of connecting lever part and on-load switch to be collided, damage the combination switch body, when the on-load switch separating brake, oil bumper can be according to the distance between required stroke adjustment oil bumper and connecting lever, and the pressure of oil bumper also can be regulated, can play the effect of eliminating bounce-back by oil bumper thus, play while having realized thus the on-load switch operation and close a floodgate spacing and eliminate separating brake and rebound, reach the operate machine requirement of characteristic of on-load switch.
The accompanying drawing explanation
Fig. 1 is "on" position structural representation of the present utility model;
Fig. 2 is gate-dividing state structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the spacing combined floodgate buffer structure of the separating brake of on-load switch of the present utility model is described in further detail.
As shown in the figure, the spacing combined floodgate buffer structure of the separating brake of on-load switch of the present utility model, comprise a connecting lever 1, the middle part of connecting lever 1 is connected to also can be at the drive lower swing of operation rotating shaft in the operation rotating shaft, the rear and front end of connecting lever 1 is respectively arranged with a roller 2, on the framework 3 of operation rotating shaft one side, be respectively arranged with and two stopping means 8 and oil bumpers 4 that roller 2 positions are relative, connecting lever 1 can make two rollers 2 optionally be pressed on stopping means 3 and oil bumper 4 under the drive of operation rotating shaft, position device 3 comprises a cushion block 5, the front of cushion block 5 is relative with the roller position of connecting lever 1 front end, cushion block 5 back sides are connected with a screw rod 6, cushion block 5 is fixedly connected on framework 3 by screw rod 6, be provided with bolster 7 between piece 5 and framework 3, bolster 7 is the Cowhells packing ring.
Its operation principle is as follows:
When on-load switch closes a floodgate, mechanism drives hexagonal axis and rotates together with connecting lever, connecting lever turns an angle afterwards and cushion block clashes into, bolster 7 is cushioned, make mechanism's stop motion, the operating mechanism that prevents on-load switch, because the strength of inertia force and switching-in spring caused more greatly stroke, causes the body of connecting lever part and on-load switch to be collided, damage the combination switch body
When the on-load switch separating brake, the roller of connecting lever 1 lower end contacts with oil bumper, the surface of oil bumper employing full thread can be according to the distance between required stroke adjustment oil bumper and connecting lever, and the pressure of oil bumper also can be regulated, can play the effect of eliminating bounce-back by oil bumper thus, realized thus that on-load switch when operation plays and closed a floodgate spacing and eliminate the separating brake bounce-back, reached the operate machine requirement of characteristic of on-load switch.
