Description
Technical field
The utility model relates to high-tension electricity equipment technical field, in particular to a kind of spring operating mechanism buffer.
Background technique
Vacuum circuit breaker is control important in electric system and protection equipment, and spring operating mechanism be in breaker not
The important component that can lack, it will not only guarantee that breaker accurately cut-offs and closes, and reliably be maintained at combined floodgate or
Person's gate-dividing state, therefore spring mechanism working performance and quality directly affect the working performance and reliability of breaker, vacuum
The characteristics of breaker is that the contact movement excess of stroke is shorter, opens, contact over travel within the scope of speed more demanding away from closing speed in stroke
It is required that lower, combined floodgate core main points are, the excess of stroke is shorter, in the lower situation of combined floodgate tip speed, it is necessary to assure vacuum circuit breaker
The reliable combined floodgate of device, because a kind of spring operating mechanism buffer of the invention is very necessary.
Utility model content
The utility model provides a kind of spring operating mechanism buffer, can solve in the prior art, and buffering effect is poor, property
It can poor, inconvenient problem with use.
The utility model provides a kind of spring operating mechanism buffer, including buffer shell, plunger, buffer
Cylinder, inner cavity and piston rod, the buffer interior of shell are provided with inner cavity；Buffer shell one end inner wall is fixedly connected with
Plunger；The plunger is connected with buffer cylinder；The buffer cylinder interior is provided with piston rod；The piston rod spacing place installation
There is plunger.
Preferably, the plunger, buffer cylinder and piston rod are arranged in inner cavity；The inner cavity is provided with hydraulic
Oil.
Preferably, the other end of the buffer shell is using piston rod as axial symmetry setting, there are six bolts.
Preferably, the buffer interior of shell is provided with first groove adaptable with plunger and buffer cylinder.
Preferably, being provided with the second groove being adapted with piston rod on the buffer cylinder.
Preferably, the inner cavity and buffer cylinder are provided with one group of hydraulic oil run-through channel: first groove and described the
Two grooves are communicated by plunger cavity.
Preferably, being provided with damping hole on the buffer cylinder.
A kind of spring operating mechanism buffer provided by the utility model, piston rod are in separating brake settling position, work as mechanism
When receiving closing operation order, piston rod moves downward under the action of mechanism switching-in spring power, buffer shell and buffer
Pressure difference is generated between cylinder, hydraulic oil is under the action of pressure difference by plunger cavity and damping hole in buffer shell and buffering
It is flowed between device cylinder.Since the outflow of damping hole limits, the speed of piston rod is also restrained.During closing operation,
Switching-in spring energy a part for giving tripping spring energy storage, offset by the buffering of hydraulic oil in buffer by another part energy
Fall.Finally, piston rod rests on combined floodgate settling position.When mechanism receives sub-switching operation order, piston rod stablizes position from closing a floodgate
It sets and starts to move right, tripping spring energy is all absorbed by the buffering counter-force of buffer, and it is steady that piston rod eventually settles at separating brake
Positioning is set, and the device cushion performance made is good, and performance is more stable.Buffer interior of shell is provided with inner cavity；Outside buffer
Shell one end inner wall is fixedly connected with plunger and plunger is disposed through cavity；Buffer cylinder is connected in plunger；In buffer cylinder
It is internally provided with piston rod；Plunger is installed in piston rod spacing place, have it is structurally reasonable, it is easy to install and use.

Fig. 2 is a kind of partial structure diagram of spring operating mechanism buffer provided by the utility model；
Fig. 3 is a kind of partial structure diagram of spring operating mechanism buffer provided by the utility model.
Description of symbols: 1- buffer shell；2- plunger；3- buffer cylinder；The inner cavity 4-；5- piston rod.
Specific embodiment
As shown in Figure 1 to Figure 3, with reference to the accompanying drawing, a specific embodiment of the utility model is retouched in detail
It states, it is to be understood that the protection scope of the utility model is not limited by the specific implementation.
A kind of spring operating mechanism buffer provided by the embodiment of the utility model, including buffer shell 1, plunger 2,
Buffer cylinder 3, inner cavity 4 and piston rod 5, the buffer outer 1 are internally provided with inner cavity 4；1 one end inner wall of buffer shell
It is fixedly connected with plunger 2；The plunger 2 is connected with buffer cylinder 3；The buffer cylinder 3 is internally provided with piston rod 5；It is described
5 spacing place of piston rod is equipped with plunger 2.
Preferably, the plunger 2, buffer cylinder 3 and piston rod 5 are arranged inside inner cavity 4；It is arranged inside the inner cavity 4
There is hydraulic oil.
Preferably, the other end of the buffer shell 1 is that there are six bolts for axial symmetry setting with piston rod 5.
Preferably, the buffer shell 1 is internally provided with first groove adaptable with plunger 2 and buffer cylinder 3.
Preferably, being provided with the second groove being adapted with piston rod 5 on the buffer cylinder 3.
Preferably, the inner cavity 4 is provided with one group of hydraulic oil run-through channel with buffer cylinder 3: first groove with it is described
Second groove is communicated by 2 cavity of plunger.
Preferably, being provided with damping hole on the buffer cylinder 3.
Working principle: piston rod 5 is in separating brake settling position, and when mechanism receives closing operation order, piston rod 5 is in machine
It is moved downward under the action of structure switching-in spring power, pressure difference is generated between buffer shell 1 and buffer cylinder 3, hydraulic oil is being pressed
It is flowed between buffer shell 1 and buffer cylinder 3 under the action of power difference by 2 cavity of plunger and damping hole.Due to damping hole
