Description
Technical field
The utility model is related to a kind of vacuum circuit breaker, more particularly to a kind of breaker spring buffer unit.
Background technology
Electric locomotive or motor-car are fitted with vacuum circuit breaker, and vacuum circuit breaker realizes that closure cut-offs work(by ecp
Can, when breaker closing, Electronic control compressed air valve is opened, by air force forward direction pusher cylinder piston, and then
Insulation push rod is promoted to realize that dynamic/static contact is closed, while compression is arranged on the back-moving spring of moving contact bottom, closure is completed；Surely
When empty breaker needs to disconnect, cylinder pressure release, back-moving spring recovers, and promotes insulation push rod and piston reverses direction to transport by elastic potential energy
It is dynamic, until piston contact cylinder bottom, dynamic/static contact disconnection.
Vacuum circuit breaker mechanism of the prior art as shown in figure 1, vacuum circuit breaker receive instruction disconnect when, back-moving spring
2 release elastic potential energys, promote resetting-mechanism 4 and insulation push rod 3 to move down, and realize that vacuum circuit breaker disconnects.
Cylinder moment pressure release during due to disconnecting, back-moving spring dynamics is very big, promotes piston slap cylinder bottom, to cylinder and
Mechanism causes mechanical shock, has a strong impact on vacuum circuit breaker mechanical life.
The content of the invention
The purpose of this utility model is to provide one kind and can improve the breaker mechanical life-span, and assembling structure it is simple it is compact,
The breaker spring buffer unit being easily achieved.
The purpose of this utility model is achieved through the following technical solutions：
Breaker spring buffer unit of the present utility model, including lower insulator upper flange, resetting-mechanism and insulation push rod,
Buffer unit is provided between the lower insulator upper flange and resetting-mechanism.
The technical scheme provided by above-mentioned the utility model is as can be seen that the breaker bullet of the utility model embodiment offer
Spring buffer unit, uses breaker spring buffer unit, buffer unit effectively to absorb breaker due to increasing electric locomotive with motor-car
To cylinder and the mechanical momentum of associated reset mechanism during disconnection, it is possible to increase the breaker mechanical life-span.Assembling structure is simply compact,
It is easily achieved.
Brief description of the drawings
Fig. 1 is the structural representation of vacuum circuit breaker mechanism of the prior art.
The structural representation of the breaker spring buffer unit that Fig. 2 is provided for the utility model embodiment is (during closure state
Buffer gear).
The structural representation of the breaker spring buffer unit that Fig. 3 is provided for the utility model embodiment is (during off-state
Buffer gear).
In figure：
1st, lower insulator upper flange, 2, back-moving spring, 3, insulation push rod, 4, resetting-mechanism, 5, buffer casting, 6, buffering
Spring groove, 7, buffer spring.
Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment for obtaining, belongs to protection domain of the present utility model.
Breaker spring buffer unit of the present utility model, its preferably specific embodiment is：
Including lower insulator upper flange, resetting-mechanism and insulation push rod, the lower insulator upper flange and resetting-mechanism it
Between be provided with buffer unit.
The buffer unit includes buffer spring, buffer casting and buffering spring groove, and the buffer casting is arranged on
On the lower insulator upper flange, the buffer spring groove is arranged on the rotation dish between the resetting-mechanism and insulation push rod
On, the buffer spring is loaded between the buffer casting and buffer spring groove.
The buffer unit is supporting in vacuum circuit breaker.
Breaker spring buffer unit of the present utility model, increases electric locomotive and buffers dress with breaker spring with motor-car
Put, buffer unit is arranged on insulator flange, is made up of parts such as buffer spring, buffer casting, buffer spring grooves, assemble
It is simple and compact for structure, it is easy to accomplish.Buffer unit is effectively absorbed when breaker disconnects to cylinder and the machinery of associated reset mechanism
Momentum, it is possible to increase breaker mechanical life-span.
Specific embodiment：
Install mechanism such as Fig. 2 (circuit breaker closing conjunction state) and Fig. 3 (breaker off-state) of breaker buffer unit additional, delay
Spring base is rushed on lower insulator upper flange, buffer spring groove is arranged on resetting-mechanism, buffer spring is arranged on buffering
Between spring base and buffer spring groove.When vacuum circuit breaker receives instruction disconnection, back-moving spring promotes resetting-mechanism and insulation to push away
Bar is moved down, and is assembled together because buffer spring groove is fastened with resetting-mechanism by screw, and buffer spring groove is with reset machine
Structure is moved down, and when the needs deceleration stopping of stroke later stage is moved to, buffer spring groove starts to compress buffer spring, buffer spring
Groove is subject to buffer spring reaction force simultaneously, realizes pushing away deceleration to resetting-mechanism and insulation the counter of push rod.Pacify buffer spring bottom
On buffer casting, buffer casting is arranged on lower insulator upper flange by screw, such mechanism disconnect momentum according to
It is secondary to be delivered on lower insulator upper flange by resetting-mechanism, buffer spring groove, buffer spring, buffer casting, realize disconnecting
Sharing for momentum, effectively reduces mechanical shock of the insulation push rod to bottomed cylinder, so as to improve the mechanical life of vacuum circuit breaker.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by the protection domain of claims.
