Specifically, make the huge problem of operating mechanism volume, a kind of scheme that the present invention proposes for what background technology was mentioned, solve because using connecting rod to cause operating mechanism total length to increase and because of the problem of two spring block form thickness increase these two aspects.
In general, the switching-in spring of circuit breaker operation mechanism is tripping spring energy storage during closing operation, and so, elastic force and the volume ratio tripping spring of switching-in spring are much larger, if switching-in spring is enclosed within outside tripping spring, it becomes possible to the problem preferably reducing operating mechanism thickness.
For this, the present invention proposes a kind of scheme, predominantly: a kind of breaker mechanical formula operating mechanism, for driving the chopper in high pressure or intermediate voltage electric power system, comprise running part module M1 and two modules of spring section module M2, described spring section module M2 includes switching-in spring 12 and tripping spring 11, and wherein, described switching-in spring 12 is enclosed within the outside of described tripping spring 11.
Using this invention can improve two springs and be arranged in juxtaposition the problem making operating mechanism thickness increase, typical design can make thickness be reduced to 300mm by 500mm.
In addition, this problem big is become for action part initiation operating mechanism length of connecting with spring section, the present invention replaces changing the connecting rod of direction of pull by introducing the chain that can change direction of pull, spring section is become in parallel with the arrangement of running part from connecting, i.e. spring section is arranged in the side of operating mechanism running part, makes the length of running part overlap with the length of spring section.
For this, described running part module M1 and spring section module M2 arrangement each other are arrangement in parallel, described spring section module M2 is arranged in the side of described running part module M1, and the side of described running part module M1 and spring section module M2 coincides mutually.
Wherein, described spring section module M2 is additionally provided with the described switching-in spring 12 of installation and the support 9 of tripping spring 11, described running part module M1 includes operating output shaft 3, energy storing drive axle 6 and supporting the wallboard 1,1 ' of described axle, and it is used for connecting plate assembly and the chain assemblies that axle is connected with spring, and multiple directive wheels 8 of Quality Initiative bar assembly transmission direction of pull, the plurality of directive wheel includes the directive wheel controlling switching-in spring chain 7,7 ' with controlling tripping spring chain 4 respectively；

Wherein, this specific embodiment can be substantially reduced the total length of operating mechanism, and the total length of spring operating mechanism can be reduced to 600mm by 800-1000mm by typical scenario.
In addition, while using above-mentioned two scheme, energy in view of switching-in spring is big, spring force is the biggest, and existing spring operating mechanism typically uses unilateral cantilever to install the connecting plate being connected with spring, its shortcoming is that stress is big and unilateral cantilever makes to be little affected by bearing capacity away from the wallboard of this connecting plate side, and whole bearing capacities acts on the wallboard of close connecting plate side, operating mechanism wallboard stress is unreasonable, and long period of operation easily damages the bearing on unilateral wallboard and bearing.
To this end, the scheme used in new invention is to be respectively provided with connecting plate in the outside of two wallboards to be connected by chain with switching-in spring seat, make active force be evenly distributed on bearing and the bearing of two wallboards, thoroughly solve the unbalanced problem of stress in existing operating mechanism.

In conjunction with foregoing invention design, the concrete technical scheme of the present invention is described in detail.
As shown in fig. 1, the operating mechanism in the present invention mainly includes running part module M1 and spring section module M2, and the most important of the present invention is that switching-in spring 12 is enclosed within spring section module M2 the outside of tripping spring 11.From figure 1 it appears that the inside and outside mode arranged of this spring saves space about 30% than spring parallel arrangement.
And, owing to switching-in spring 12 is enclosed within outside tripping spring 11, and switching-in spring 12 and tripping spring 11 have motion in operating mechanism course of action, in order to avoid the phase mutual friction and colliding with in motor process of interior outer spring, between inner spring and outer spring, there is spring isolating cylinder 10.
Meanwhile, the switching-in spring guide ring 16 manufactured with antifriction material is set in switching-in spring bearing 14, the tripping spring guide ring 15 manufactured with antifriction material is set outside tripping spring bearing 13, reduces kinetic friction force further.
Wherein, illustrating spring section module M2 of the present invention, specifically, the function of described spring section module M2 is to accommodate switching-in spring 12 and tripping spring 11, and coordinates the motion of connecting plate in running part module M1 to provide suitable spring tension.Wherein, above-mentioned spring is an energy storage component of the present embodiment compact spring operating mechanism, operating mechanism drives open circuit to take to carry out the energy of closing operation and sub-switching operation and be all from the two spring, wherein, periphery at switching-in spring 12 and tripping spring 11 is supporting and connection member, mainly includes support 9, spring isolating cylinder 10, tripping spring bearing 13, switching-in spring bearing 12, tripping spring chain 4, switching-in spring chain 7,7 '.
Wherein, switching-in spring 12 is in the operating process of operating mechanism, and one end relies on elastic compression in the inner side of support 9, is always maintained at maintaining static, and the other end is pressed on switching-in spring bearing 14, with moving.Smooth and easy for ensureing motion, switching-in spring guide ring 16 is installed inside switching-in spring bearing 14.
Wherein, switching-in spring bearing 14 connects above with connecting bolt and joint and two switching-in spring chains 7,7 ' are fixing, pull this chain just can move switching-in spring bearing 14 and compress switching-in spring 12 simultaneously, can and be stored in switching-in spring 12 in the pulling force from chain is converted into spring.
Wherein, operating mechanism is in thermal energy storage process, and the motor in running part module M1 drives energy storing drive axle to rotate by reduction gearing, and the energy storing drive axle connecting plate 5,5 ' on this axle rotates therewith, and pulls two switching-in spring chains 7,7 ', it is achieved energy storage.In thermal energy storage process, switching-in spring bearing 14 moves right in FIG, compression spring.
After operating mechanism energy storage completes, closing operation can be carried out.After combined floodgate trigger element in running part module M1 starts, switching-in spring bearing 14 is moved to the left in FIG, pull two switching-in spring chains 7,7 ', energy storing drive axle connecting plate 5,5 ' is made to rotate counterclockwise around energy storing drive axle 6 after changing direction of pull by directive wheel 8, and drive the cam on this axle to oppress the roller being connected with operation output shaft 3, make operation output shaft 3 rotate clockwise, drive operation connecting lever and moving contact of breaker motion, it is achieved breaker closing.Meanwhile, the operation output shaft connecting plate 2 being positioned at N in the middle part of operating mechanism moves together with operation output shaft 3, pulls the tripping spring chain 4 being positioned at N in the middle part of operating mechanism to move.
Wherein, one end of tripping spring 11 is fixed together by elastic force with the inner side of support 9, is always maintained at maintaining static, and the other end is pressed on tripping spring bearing 13, moves with tripping spring bearing 13.Smooth and easy for ensureing motion, tripping spring guide ring 15 is installed outside tripping spring bearing 13.The centre of tripping spring bearing 13 is by connecting bolt and joint and a fixing connection of tripping spring chain 4, pull this chain just can move tripping spring bearing 13 and compress tripping spring 11 simultaneously, can and be stored in tripping spring 11 in the pulling force from chain is converted into spring.
In aforementioned making process, tripping spring chain 4 pulls tripping spring bearing 13 to move right in FIG, compression tripping spring 11, can and be stored in tripping spring 11 in the pulling force from chain is converted into spring, carries out separating brake for next step chopper and stores energy.
After operating mechanism has closed a floodgate, sub-switching operation can be carried out.After the separating brake trigger element of running part module M1 starts, tripping spring bearing 13 is moved to the left in FIG, pull the tripping spring chain 4 being positioned at N in the middle part of operating mechanism, operation output shaft connecting plate 2 is made to rotate counterclockwise around operation output shaft 3 after changing direction of pull by directive wheel 8, and drive the operation connecting lever on this axle and moving contact of breaker motion, it is achieved breaker open operation.
During aforesaid energy storage, combined floodgate and separating brake, in order to support the counteracting force that spring force produces, need to be reliably supported on two wallboards 1,1 ' aforementioned operation output shaft 3 and energy storing drive axle 6.Bearing the supporting force of maximum in order to realize the physical dimension of minimum, need to be evenly distributed in load on two wallboards 1,1 ' as far as possible, unbalanced structure is accomplished by strengthening the intensity of part, it is impossible to realize compact design.
In such as Fig. 1 embodiments of the invention, the stress point of above-mentioned two spring is evenly distributed in operating mechanism.First, tripping spring chain 4 being arranged in the middle part N of operating mechanism, the distance of the wallboard 1 and 1 ' away from both sides is equal, being distributed in the tension uniform of tripping spring chain 4 on two wallboards 1,1 '.Secondly, it it is two by the chain design being connected with switching-in spring, and two switching-in spring chains 7,7 ' are arranged on outside S1 and the S2 direction of wallboard 1,1 ', combined floodgate cam in operating mechanism running part module M1 is in the centre of wallboard 1,1 ', this structure is the most rational supporting structure in mechanical system, the stress that two wallboard upper bearing (metal)s prop up bearing is identical, and the stress balance of both sides, is preferable stress axle construction.
In order to further save space, can see that in fig. 2, article two, switching-in spring chain 7,7 ' is not arranged in the outermost of operating mechanism, switching-in spring bearing 14 is in tilted layout relative to the installation axle of directive wheel 8 with the junction point line of two switching-in spring chains 7,7 ', 45 ° ± 15 ° of angle of inclination.In the case of 45 ° of typical sizes angle of inclination, when two mount point distances 280mm, in fig. 2, the left and right distance of above-mentioned 2 is reduced in size to 198mm, reduces 41%.In sum, be in tilted layout two switching-in spring chains 7,7 ' can the gauge of obvious reduction operation mechanism, design the operating mechanism of compact.
In structure as shown in Figure 4, in order to ensure, when spring section module M2 and running part module M1 operate after totally connecting, relative movement does not occur, connecting portion is designed with stop bit shoulder 17.After totally connecting, the pressure of connecting bolt directly acts on stop bit shoulder 17, when operation, the pulling force of chain is also directly delivered on stop bit shoulder 1, the direction of these active forces is all to make spring section module M2 and running part module M1 more securely link together, as long as stop bit shoulder 17 does not damage, above-mentioned two part would not have relative movement.And traditional plane attachment structure is big in stress and deposits in the case of a shock, it is easy to relative displacement occurring, finally makes connecting bolt bear shearing force, bolt can be cut off by long period of operation, makes operating mechanism thoroughly lose efficacy.
In the present invention, in order to control spring tension direction, by chain design in drive system, total switching-in spring chain 7,7 ' and 4 three chains of tripping spring chain in operating mechanism.Chain is element conventional in machine driving, and kind is a lot, but is applied in operating mechanism to possess the characteristic of reliability service under long-term heavy load operating mode.Preferential selection heavy duty leaf chain in aforementioned operation mechanism, preferred specification is 0.5 inch to 1.5 inches, and the leaf chain of these several specifications operates steadily when by directive wheel, and the limit load of leaf chain is less than the maximum pull of spring simultaneously.If selecting the leaf chain less than 0.5 inch, leaf chain, more than the load of leaf chain, is broken by spring tension；If selecting the leaf chain more than 1.5 inches, when chain is by directive wheel control direction, long pitch makes chain too small with directive wheel surface contact surface, on the one hand abrasion is increased the weight of, on the other hand, having slight beating in motor process, the output speed characteristic making operating mechanism is unstable.Comprehensive factors above, is limited to 0.5 inch to 1.5 inches by the dimensions of leaf chain.Another is roller chain through commonly used chain, can be equally used for the transmission of operating mechanism in the present invention.Along with continuing to bring out of new material, it is also possible to the high-strength flexible that will have like function connects band in this operating mechanism.
In another embodiment as shown in Figure 3, it is directed to take turns 8 designs at operating mechanism two ends B1 and B2.Different from the design of Fig. 1, in FIG, 5 directive wheels 8 are arranged in the B1 end of support 9, and in the scheme of Fig. 3,3 directive wheels 8 controlling switching-in spring chain 7,7 ' are still positioned at B1 end；And two directive wheels controlling tripping spring chain 4 are positioned at B2 end, the operation output shaft connecting plate 2 being still positioned at N in the middle part of operating mechanism pulls a tripping spring chain 4, then controls direction of pull by the directive wheel of B2 end, it is achieved the sub-switching operation of operating mechanism.
In sum, by above-mentioned new design, the operating mechanism of the present invention has been realized in compact conformation, stress balance and designs simple.Compared with operating mechanism existing with this area, while compact conformation, significantly reduce cost.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
