Description
Technical field
The utility model relates to spring operating mechanism, and particularly the combined floodgate of vacuum circuit-breaker medi-spring operating mechanism keeps structure.
Background technology
The against vacuum circuit breaker, need behind combined floodgate, maintain the pressure between the dynamic/static contact in the primary conductive loop, so that good electrical contact is arranged behind combined floodgate, reduce the primary conductive resistance in circuit and keep the stability of resistance, combined floodgate in this sky circuit breaker of will looking for the truth keeps structure to stablize, otherwise vacuum circuit-breaker can take place refuse to close or increase the phenomenons such as components and parts of burning in the primary conductive loop because of resistance.Now general solution is to transmit contact pressure by four connecting rods to make it fasten the dropout semiaxis to buckle in making process, like this buckle and take off between mouthful semiaxis and do not have relative motion, the effect of formation snap close.If want close a floodgate to keep stable, will strengthen buckle and take off pressure between mouthful semiaxis, but intensified pressure the time, when fault is threaded off, will increase tripping force, reduce the sensitivity of threading off, the phenomenon that serious words can cause vacuum circuit-breaker to refuse branch or burn release electromagnet.Because above-mentioned two require to be difficult to satisfy simultaneously, therefore the spring operating mechanism of vacuum circuit-breaker of the prior art often can not satisfy above-mentioned requirements simultaneously, makes mechanism have operation hidden danger.So, just need a kind of combined floodgate to keep stable, the combined floodgate of the sensitive vacuum circuit-breaker of threading off simultaneously keeps structure.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that stability that the existing in prior technology vacuum circuit-breaker close a floodgate to keep and the sensitivity of dropout can not be satisfied simultaneously, and a kind of vacuum circuit-breaker combined floodgate maintenance structure is provided.This device can make the vacuum circuit-breaker combined floodgate keep stable, and it is sensitive to guarantee again to thread off.
The technical solution that realizes the foregoing invention purpose is such: the combined floodgate that is provided keeps structure to comprise closing keeping device, transmission device and the trip gear that is provided with on lead frame and the framework, it is characterized in that:
Closing keeping device is made up of sprocket shaft, keep plate and pawl, and keep plate is provided with alignment pin, and keep plate is fixed on the sprocket shaft, and pawl is connected with keep plate by connecting pin, and torsion spring is housed on the connecting pin;
Transmission device is made up of big connecting lever, direction board and bent plate, big connecting lever is fixed on the connecting lever axle, and direction board is provided with trundle, and big connecting lever is connected by the indication pin with direction board, direction board is connected by trundle with the bent plate lower end, and the upper end of bent plate is connected with connecting pin in the closing keeping device;
Trip gear is made up of dropout semiaxis, buckle and reset tension spring, and the dropout semiaxis is provided with draw-in groove, and buckle is fixed on the buckle axle, and the buckle axle is provided with draw-in groove, and an end of reset tension spring is connected with the lower end of buckle, and the other end is hooked on the lead frame.
Compared with prior art, the beneficial effects of the utility model are: adopt secondary semiaxis snap close force-reducing device, when closing a floodgate maintenance, by buckle to the braking of semiaxis and pawl to the buckle axle, form metastable combined floodgate hold mode, and do not act directly on effectively on the buckle, make the dropout merit reduce, strengthen the sensitivity of threading off.

Embodiment
As shown in drawings: the utility model comprises lead frame 1 and closing keeping device, transmission device and trip gear,
Closing keeping device is made up of sprocket shaft 9, keep plate 10 and pawl 14, be welded with alignment pin 13 on the keep plate, keep plate 10 is installed on the sprocket shaft 9, and pawl 14 is connected by connecting pin 12 with keep plate 10, torsion spring 3 is contained on the connecting pin 12, for pawl 14 provides elastic force.
Transmission device is made up of big connecting lever 17, direction board 7 and bent plate 15, big connecting lever 17 is welded on the connecting lever axle 6, indication pin 5 is welded on the big connecting lever 17, direction board 7 is welded on the indication pin 5, trundle 8 is welded on the direction board 7, the lower end of bent plate 15 is connected on the trundle 8, and the upper end of bent plate 15 is connected on the connecting pin 12 in the closing keeping device.
Trip gear is made up of dropout semiaxis 2, buckle 11 and reset tension spring 16, dropout semiaxis 2 is provided with draw-in groove, and buckle 11 is fixed on the buckle axle 4, and buckle axle 4 is provided with draw-in groove, one end of reset tension spring 16 is connected with the lower end of buckle 11, and the other end is hooked on the lead frame 1.
Corresponding axle, pin on closing keeping device, transmission device and the trip gear, respectively be arranged on lead frame 1 on the corresponding socket joint connection of eyelet.
Operation principle of the present utility model is as follows:
In the making process, the buckle 11 in the described trip gear is being buckled under the effect of reset tension spring 16 on the draw-in groove of dropout semiaxis 2, and buckle 11, buckle axle 4 and dropout semiaxis 2 are static at this moment; Simultaneously, big connecting lever 17 in the transmission device clockwise rotates, be welded on indication pin 5 on the big connecting lever 17, be welded on the direction board 7 on the indication pin 5 and the trundle 8 that is welded on the direction board 7 also rotates along with the rotation of big connecting lever 17, at this moment, being connected bent plate 15 on the trundle 8 is also being driven and is being moved upward; The other end of bent plate 15 links together by the connecting pin in the closing keeping device 12 and keep plate 10, pawl 14, and the rotation of bent plate 15 makes keep plate 10 rotate counterclockwise around sprocket shaft 9; Keep plate 10 keeps relative static position with the alignment pin 13 of pawl 14 by torsion spring 3, connecting pin 12 and on being welded on keep plate 10.
When combined floodgate put in place, keep plate 10 drove pawls 14 and slips over buckle axle 4, and the effect by torsion spring 3 is stuck in the draw-in groove of buckle axle 4, and at this moment, all parts are in static relatively state, the hold mode of just closing a floodgate.
When separating brake, dropout semiaxis 2 clockwise rotates, buckle 11 drives buckle axle 4 and rotates under the effect of back-moving spring 16, pawl 14 can not be stuck on the buckle axle 4, so the relative static conditions of remaining parts changes, pawl 14 drives keep plate 10 and clockwise rotates, and bent plate 15 moves downward, and makes big connecting lever 17 rotate counterclockwise until the separating brake position around connecting lever axle 6.
