Of the present utility modelly to be characterised in that:
1, propose strengthen its vibrational energy loss by increasing the radial non-rectilinear propagation path of vibration wave, weaken breaker operation mechanism action produce the method for vibration effect.For vibration wave is propagated along operating mechanism radial alignment merely, add the path that it is propagated along operating mechanism hoop, its role is to:

1) when vibration wave is propagated wherein, because reasons such as the mutual motions of the material microcosmic crystal grain that ripple causes when material internal is propagated, quite a few mechanical vibrational energy is consumed, and is converted into the interior energy of material, causes the oscillation intensity of the vibration wave after damping material is propagated to reduce.
2) when the Central Symmetry connector adopting damping material to make has aforesaid curved structure, propagation path when vibration wave is propagated wherein lengthens, and the consumption effect of material damping characteristic to vibration wave energy strengthens further.
Relative to prior art, the utility model has following beneficial effect:
By the Central Symmetry connector with radial curved structure adopting damping material to make, enhance energy loss when vibration wave is propagated wherein, effectively reducing vibration that operating mechanism action produces to the impact of breaker body, operating mechanism and link thereof etc. limits the communication process of vibrational energy, the problem such as to loosen of the dither between the circuit breaker dynamic/static contact that the vibration that effectively inhibit operating mechanism action to produce causes, the fatigue and fracture of insulated tension pole, other components of circuit breaker and link thereof.
For damping material, when vibration wave is propagated wherein, because reasons such as the mutual motions of the material microcosmic crystal grain that vibration wave causes when material internal is propagated, quite a few mechanical vibrational energy is consumed, be converted into the interior energy of material, cause the mechanical wave oscillation intensity after damping material is propagated to reduce.This curved structure also weakens oscillation intensity, absorbing vibrational energy further by formation standing wave, the folding increasing vibration wave, reflection.Further, combinationally using of damping material and Central Symmetry connector curved structure, extends vibration wave trajectory, the consumption of damping material to vibration wave energy is strengthened further.

[embodiment]
As shown in Figure 1,1 for supporting operating mechanism crossbeam for breaker operation mechanism arrangements of elements figure common at present; 2 is the fixing operating mechanism side of using plate, and it is bolted on crossbeam 1, and material is generally steel plate; 3 for connecting the connector of operating mechanism energy-storage units, and it is by the bolt side of being connected directly between plate 2; 4 is the drive link of operating mechanism, and its upper end connects the moving contact in arc control device; 5 is switch bearing; 6 is the energy-storage units of operating mechanism, may be specifically the energy storage device of spring, pneumatic or hydraulic pressure mechanism.The vibration wave that operating mechanism energy-storage units 6 action produces along the connector 3 upwards side's of propagating into plate 2, then propagates into the parts such as switch bearing 5 by crossbeam 1.
Refer to shown in Fig. 2, the utility model proposes a kind of radial non-rectilinear of ripple that utilizes and propagate the structure weakening operating mechanism vibration, on above-mentioned vibration wave trajectory, add the buffering connector 7 that damping material is made.As shown in Figure 2, the buffering connector 7 (in Fig. 2 shown in shade) that damping material is made is added between square plate 2 and connector 3, the vibration wave that energy-storage units 6 action produces propagates into bolster 7 by connector 3, the then side's of propagating into plate 2 again, and then propagate on crossbeam 1, switch bearing 5 and Switch main body.According to the method that the utility model provides, the structure of appropriate design damping material buffering connector 7, can change vibration wave trajectory, reach the object of vibration damping.
Damping material in the utility model refers to the material with damping characteristic, and this damping characteristic can consume extraneous mechanical vibrational energy, reaches the effect of vibration damping.Typical damping material has aluminum alloy materials, Cu alloy material, material with carbon element and organic material etc., and in the utility model, the damping material of indication includes but not limited to aforesaid typical damping material.
Under normal circumstances, vibration wave is radially outwards propagated after propagating into buffering connector 7 by connecting bolt from connector 3, then by the connecting bolt side of propagating into, outer ring plate 2, and then propagate on crossbeam 1.In order to weaken vibration intensity of wave further and consume its energy, the utility model proposes the buffering connector with radial curved structure, add the approach that vibration wave is propagated along its hoop.
Be a kind of typical structure of the damping material buffering connector 7 with radial curved structure shown in Fig. 3, symmetrical structure centered by damping material buffering connector in figure, it is made up of three parts: width is r
1inner ring 10, width be r
2outer shroud 20, between inner ring 10 and outer shroud 20, width is the connection spoke 30,40,50,60 of h, namely three is cast as one during fabrication.
4 perforates A, B, C, D in inner ring 10 and 4 perforates a, b, c, d on outer shroud 20 are circumferentially equidistantly being evenly arranged separately, and line aACc and bBDd is when being positioned on the angular bisector between spoke 30,40,50,60, hole A, B, C, D are connected for the bolt cushioned between connector 7 with operating mechanism connector 3, and hole a, b, c, d are then connected for the bolt cushioned between connector 7 with square plate 2.The vibration wave propagating into A, B, C, D point from operating mechanism connector 3 is propagated along the hoop of inner ring 10, on quarter turn between any two bolt tie points, on the one hand, if the vibration wave of relative motion meets the condition that standing wave is formed, then in this section of region, form standing wave, vibration wave no longer elsewhere is propagated; On the other hand, the vibration wave of relative motion, after meeting, also can weaken between part component mutually.Even if still can be propagated into the vibration wave on outer shroud 20 after above-mentioned two aspect effects by spoke 30,40,50,60, on outer shroud 20 on any one quarter turn (as between a ' b ', b ' c ', c ' d ', d ' a '), above-mentioned two kinds of damping effects still exist, and will weaken oscillation intensity further.
Equal and number of aperture 3≤n≤8 of number of aperture on inner ring 10, outer shroud 20, perforate should equidistantly be evenly distributed on circumferentially whole, and the connection spoke number between inner ring 10 and outer shroud 20 should equal number of aperture n and angle between adjacent spoke is equal, is

Now, vibration wave propagates into the A in damping material connector inner ring 10 by connector in Fig. 23 and bolt, B, C, D place, on quarter turn in inner ring 10 between any 2, vibration wave is mainly circumferentially propagated in opposite directions, arrive spoke inner termination position (A ', B ', C ', D ') after, a ' on damping connector outer shroud 20 is propagated into by connecting spoke along the direction of arrow in Fig. 3, b ', c ', d ' place, (as a ' b ' on any one quarter turn on outer shroud 20, b ' c ', c ' d ', between d ' a '), vibration wave is circumferentially propagated in opposite directions, point of arrival a, b, c, to propagate in Fig. 2 on square plate 2 by bolt again after d.When vibration wave is propagated along any one quarter turn in inner ring in Fig. 3 10, add the approach that it is circumferentially propagated, extend the path of wave traveling, enhance the consumption of damping material to vibrational energy.
At this damping material buffering connector 7 with on the interface of other parts 2,3 of operating mechanism, the refraction of vibration wave can be there is.Simultaneously, at this, there is the position (in as Fig. 3 a ', b ', c ', d ') of wave trajectory generation turnover in the Central Symmetry connector of radial curved structure, vibration wave is easy to repeatedly reciprocating reflection occurs, and this is also equal to and adds the propagation path of ripple in this connector inside.
The second has the Central Symmetry damping material connecting-piece structure figure of radial curved structure as shown in Figure 4, and the difference of itself and Fig. 3 is, it is by inner ring 100, middle ring 200, outer shroud 300, interior spoke (A
1~ A
6) and outer spoke (B
1~ B
6) composition, in inner ring 100, number of aperture n equals number of aperture (3≤n≤8) on outer shroud 300 and is evenly equally distributed on circumferentially, and inside and outside spoke number equals number of aperture n and mutual angle
and inside and outside spoke is all positioned on the angular bisector between adjacent apertures.Vibration wave has propagation path in the Central Symmetry damping material connector of radial curved structure as shown in Figure 4 at this.
As can be seen here, when vibration wave is propagated in the Central Symmetry damping material buffering connector with radial curved structure, propagation path there occurs obvious change, adds the approach that it is circumferentially propagated, extend the path of wave traveling, enhance the consumption of damping material to vibrational energy.The radial curved structure of this damping material of appropriate design buffering connector, stops by forming standing wave wherein wave direction other places to be propagated or utilizes the mutual weakening of the vibration wave of relative motion, reaching the object of damping vibration energy.Meanwhile, vibration wave this have radial curved structure damping material buffering connector and adjacent component between propagate time, its folding, reflection process be also consume vibrational energy, damping vibration intensity important means.Adopt the effectiveness in vibration suppression of said method obviously different from the situation of not adding in Fig. 1 when damping material cushions connector.
In sum, vibrate in breaker operation mechanism on wave trajectory, by adding the Central Symmetry buffering connector with radial curved structure that damping material is made, add the approach that vibration wave is circumferentially propagated, too increase folding, reflection process when vibration wave is propagated between damping material inside and different materials parts simultaneously.Above-mentioned design obviously can weaken the propagation of vibration that breaker operation mechanism action produces on circuit breaker performance and the impact in life-span and as far as possible damping vibration energy, the problem such as loosening of the dither between the circuit breaker dynamic/static contact that the vibration that can effectively suppress operating mechanism action to produce causes, the fatigue and fracture of insulated tension pole, other components of circuit breaker and link thereof.
