Description
Technical field
A kind of bounce-proof device is the utility model is related to, especially a kind of breaker bounce-proof device.
Background technology
Breaker is important high-voltage electrical apparatus element, and the length in its life-span is that the leading indicator of quality and evaluation is carried out to it
One of.Existing breaker is mainly by the vacuum interrupter and and vacuum moving of the dynamic and static contact of the internally provided with vacuum being fixed in shell
The shackle rod of contact connection, and the breaking motion composition being connected with shackle rod, the various models being such as used
Breaker.Though these breakers can close as needed or the high-tension line of disjunction distribution network system, but also there is not
Foot part, first, the combined floodgate of breaker is completed by the vacuum moving in vacuum chamber, the mechanical collision of static contact, because of its warp
Often make stronger crash-active, direct consequence be mutually wear it is more serious；Secondly, vacuum during breaker closing is dynamic and static
The spring starting the arc between contact can also aggravate the abrasion of contact, and produce overvoltage, and this not only severely impacts the use longevity of itself
Life, also endangers other electrical equipments；Again, for fast chopper, because its actuation time is extremely short, vacuum moving contact and open circuit are transported
The responsiveness of motivation structure quickly, in addition to the heavy wear and spring that more easily cause contact, during breaking motion separating brake
Vacuum moving contact resilience can also be driven often by crossing fast motion, make to produce arcing between vacuum moving contact and static contact, further
The contact of ablation two, aggravate its abrasion, easily cause the acceleration of breaker to be scrapped.
Utility model content
The technical problems to be solved in the utility model is to overcome weak point of the prior art, there is provided one kind avoids vacuum
The breaker bounce-proof device to be bounced between dynamic and static contact.
To solve technical problem of the present utility model, used technical scheme is that breaker bounce-proof device includes one
End connection vacuum moving contact, the other end connect breaking motion, the middle shackle rod for convex rod, and fixed vacuum extinction
The case for circuit breaker of room, particularly：
Cushion collar is set with outside the convex rod of the shackle rod；
The bottom of the cushion collar contradicts with flexible gaskets and connected；
The flexible gaskets are fixedly connected with case for circuit breaker.
Further improvement as breaker bounce-proof device：
Preferably, flexible gaskets are fixedly connected through elastic ring with case for circuit breaker.
Preferably, cushion collar and spacing≤vacuum moving contact of the convex rod of shackle rod and the spacing of vacuum static contact.
Preferably, weight >=2kg of cushion collar.
Preferably, elastic ring is mixture more than one or both of turn, disc spring circle, rubber ring.
It is relative to the beneficial effect of prior art：
After such structure, when breaker closing, cushion collar has not only acted as spacing effect, also absorbs and resolves
The kinetic energy that road motion is moved upward to behind position, avoid the spring triggered between vacuum moving, static contact by strong collision；When disconnected
During the device separating brake of road, flexible gaskets absorb the kinetic energy after breaking motion moves downward in place, and cooperate with cushion collar to keep away together
Exempt from the rebound motion of breaking motion, prevent the drawing because of caused by the resilience of vacuum moving contact between vacuum moving, static contact
Arc phenomenon.Both the service life of breaker had greatly been extended, the harm to other electrical equipments has been turn avoid, also reduces confession
The cost of distribution network system operation, the breaker for making it be extremely easy to widely be commercially used for distribution network system high pressure circuit
On.
Brief description of the drawings
Fig. 1 is a kind of basic structure schematic diagram of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the composition of breaker bounce-proof device is as follows：
Vacuum interrupter 1 is fixed with case for circuit breaker 8.Vacuum moving contact 2 and centre in vacuum interrupter 1 are convex rod
Shackle rod 4 connect, the other end of shackle rod 4 is connected with breaking motion 7.It is set with outside the convex rod of shackle rod 4
Its bottom contradicts the cushion collar 3 of connection with flexible gaskets 5；Wherein, spacing≤vacuum moving of cushion collar 3 and 4 convex rod of shackle rod
The spacing of contact 2 and vacuum static contact, now it is chosen less than the spacing 1 (can be 1-2) of vacuum moving contact 2 and vacuum static contact
Mm, the weight of cushion collar 3 are 2kg (can >=2kg).Flexible gaskets 5 are fixedly connected through elastic ring 6 with case for circuit breaker 8；Wherein,
Elastic ring 6 is mixture more than one or both of turn, disc spring circle, rubber ring, and now selection is turn.
The present apparatus when breaker closing, breaking motion 7 drive shackle rod 4 and vacuum moving contact 2 thereon to
Upper motion, before vacuum moving contact 2 completes feed motion into contact with vacuum static contact, the convex rod collision of shackle rod 4
To cushion collar 3, the kinetic energy of breaking motion 7, shackle rod 4 and vacuum moving contact 2 is absorbed and discharged by cushion collar 3, is prevented
Strong collision between vacuum moving, static contact.When breaker open operation, breaking motion 7 drives shackle rod 4 and thereon
Vacuum moving contact 2 moves downward, and before the breaking execution of motion 7, the convex rod of shackle rod 4 collides flexible gaskets
5, the kinetic energy of breaking motion 7, shackle rod 4 and vacuum moving contact 2 is delivered on flexible gaskets 5 and elastic ring 6, realized
Reduction of speed, discharge kinetic energy, the effect for preventing breaking motion 7 from rebounding.
Obviously, those skilled in the art can to breaker bounce-proof device of the present utility model carry out it is various change and
Modification is without departing from spirit and scope of the present utility model.So, if belonging to these modifications and variations of the present utility model
Within the scope of the utility model claims and its equivalent technologies, then the utility model is also intended to comprising these changes and modification
Inside.
