The invention discloses a kind of breaker bounce-proof device.It includes one end and connects vacuum moving contact (2), the breaking motion (7) of other end connection, the shackle rod (4) that centre is convex rod, and the case for circuit breaker (8) of fixed vacuum interrupter (1), particularly cushion collar (3) is set with outside the convex rod of shackle rod (4), the bottom of cushion collar (3) is contradicted with flexible gaskets (5) and is connected, and flexible gaskets (5) are fixedly connected with case for circuit breaker (8).It had both greatly extended the service life of breaker, turn avoid the harm to other electrical equipments, also reduces the cost of distribution network system operation, made it be extremely easy to widely be commercially used on the breaker of distribution network system high pressure circuit.
Description
Technical field
The present invention relates to a kind of bounce-proof device, 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 the leading indicator that quality is carried out to it and is evaluated
One of.The main vacuum interrupter and and vacuum moving by the dynamic and static contact of the internally provided with vacuum being fixed in shell of existing breaker
The shackle rod of contact connection, and the breaking motion composition being connected with shackle rod, the various models such as used
Breaker.Though these breakers can close as needed or disjunction distribution network system high-tension line, but also exist not
Foot part, first, the combined floodgate of breaker are that vacuum moving in vacuum chamber, the mechanical collision of static contact are completed, because of its warp
Often make stronger crash-active, direct consequence is mutually to wear and tear 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, aggravates its abrasion, easily causes the acceleration of breaker to be scrapped.
The content of the invention
The technical problem to be solved in the present invention for overcome weak point of the prior art there is provided one kind avoid vacuum moving,
The breaker bounce-proof device bounced between static contact.
To solve the technical problem of the present invention, the technical scheme used is breaker bounce-proof device connects including one end
Vacuum moving contact, the breaking motion of other end connection, the middle shackle rod for convex rod are connect, and fixes vacuum interrupter
Case for circuit breaker, 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 is connected；
The flexible gaskets are fixedly connected with case for circuit breaker.
It is used as the further improvement of 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.
Beneficial effect relative to prior art is：
After such structure, when breaker closing, cushion collar has not only acted as spacing effect, also absorbs and resolves
Kinetic energy that road motion is moved upward to behind position, it is to avoid because of spring that strong collision triggers between vacuum moving, static contact；When disconnected
During the device separating brake of road, flexible gaskets absorb the kinetic energy after breaking motion is moved downward in place, and cooperate with cushion collar together, keep away
The rebound motion of breaking motion is exempted from, has prevented to draw 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 invention.
Embodiment
The preferred embodiment of the present invention 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 in vacuum interrupter 1 is with middle for 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 being connected with flexible gaskets 5；Wherein, spacing≤vacuum moving of cushion collar 3 and the convex rod of shackle rod 4
The spacing of contact 2 and vacuum static contact, is now 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 is 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 driving 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 driving shackle rod 4 and thereon
Vacuum moving contact 2 is moved 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 carry out various changes and modification to the breaker bounce-proof device of the present invention
Without departing from the spirit and scope of the present invention.So, will if belonging to right of the present invention to these modifications and variations of the invention
Ask and its equivalent technologies within the scope of, then the present invention be also intended to comprising these change and modification including.
