Specifically, make the huge problem of operating mechanism volume for what mention in background technology, a kind of scheme the present invention proposes, solves because using connecting rod to cause that operating mechanism total length increases and increasing the problem of this two aspect because of two spring block form thickness.
In general, the switching-in spring of circuit breaker operation mechanism is tripping spring energy storage in closing operation process, and so, the elastic force of switching-in spring and volume ratio tripping spring are much larger, if switching-in spring is enclosed within to tripping spring outside, just can reduce preferably the problem of operating mechanism thickness.
For this reason, the present invention proposes a kind of scheme, be mainly: a kind of breaker mechanical formula operating mechanism, for driving the circuit breaker of 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.
Adopt this invention can improve two springs and be arranged in juxtaposition the problem that operating mechanism thickness is increased, typical design can make thickness be reduced to 300mm by 500mm.
In addition, connect with spring section for action part and cause large this problem of operating mechanism length change, the present invention can change direction of pull chain by introducing replaces the connecting rod that can not change direction of pull, spring section is become to parallel connection with the arrangement of running part from connecting, be the side that spring section is arranged in operating mechanism running part, the length of running part and the length of spring section are overlapped.
For this reason, described running part module M1 and spring section module M2 arrangement are each other 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 overlaps mutually.
Wherein, in described spring section module M2, be also provided with the support 9 that described switching-in spring 12 and tripping spring 11 are installed, described running part module M1 comprises operation output shaft 3, energy storing drive axle 6 and supports the wallboard 1,1 ' of described axle, and the connecting plate assembly and the chain assemblies that are connected with spring for axle, and Quality Initiative bar assembly transmits multiple directive wheels 8 of direction of pull, described multiple directive wheels comprise respectively control switching-in spring chain 7,7 ' with the directive wheel of control tripping spring chain 4;

Wherein, the inner side of one end of tripping spring 11 and support 9 is fixed together by elastic force, keeps maintaining static always, and the other end is pressed on tripping spring bearing 13, with 13 motions of tripping spring bearing.Smooth and easy for ensureing motion, in tripping spring bearing 13 outsides, tripping spring guide ring 15 is installed.The centre of tripping spring bearing 13 is fixedly connected with a tripping spring chain 4 by connecting bolt and joint, pull this chain just can compress tripping spring 11 by mobile tripping spring bearing 13 simultaneously, can and be stored in tripping spring 11 be converted into the interior of spring from the pulling force of chain.
In aforementioned making process, tripping spring chain 4 pulls tripping spring bearing 13 to move right in Fig. 1, compression tripping spring 11, can and be stored in tripping spring 11 be converted into the interior of spring from the pulling force of chain, for next step circuit breaker carries out separating brake storage power.
After operating mechanism has closed a floodgate, can carry out sub-switching operation.After the separating brake trigger element of running part module M1 starts, tripping spring bearing 13 is moved to the left in Fig. 1, pull the tripping spring chain 4 that is positioned at operating mechanism middle part N, change and make to operate output shaft connecting plate 2 after direction of pull and rotate counterclockwise around operation output shaft 3 by directive wheel 8, and drive operation connecting lever and the moving contact of breaker motion on this axle, realize breaker open operation.
In aforesaid energy storage, combined floodgate and separating brake process, for the reaction force that support spring power produces, aforementioned operation output shaft 3 and energy storing drive axle 6 need to be bearing in reliably on two wallboards 1,1 '.Bear maximum supporting force in order to realize minimum physical dimension, load need to be evenly distributed in to two wallboards 1,1 ' upper as far as possible, unbalanced structure just need to strengthen the intensity of part, cannot realize compact design.
In as Fig. 1 embodiments of the invention, the stress point of above-mentioned two springs is evenly distributed in operating mechanism.First, tripping spring chain 4 is arranged in to the middle part N of operating mechanism, equates apart from the distance of the wallboard 1 on both sides and 1 ', by being distributed on two wallboards 1,1 ' of the tension uniform of tripping spring chain 4.Secondly, it is two by the chain design being connected with switching-in spring, and two switching-in spring chains 7,7 ' are arranged on wallboard 1,1 ' outside S1 and S2 direction, combined floodgate cam in operating mechanism running part module M1 is in wallboard 1,1 ' centre, this structure is the most rational supporting structure in mechanical system, two wallboard upper bearing (metal) supporting bases stressed identical, and the stress balance of both sides are desirable stressed axle construction.
In order further to save space, in Fig. 2, can see, article two, switching-in spring chain 7,7 ' is not arranged in the outermost of operating mechanism, switching-in spring bearing 14 and two switching-in spring chains 7,7 ' tie point line are in tilted layout with respect to the installation shaft of directive wheel 8,45 ° ± 15 °, angle of inclination.In the situation of 45 °, typical sizes angle of inclination, two mounting points, during apart from 280mm, in Fig. 2, the left and right distance size of above-mentioned 2 is reduced to 198mm, reduces 41%.In sum, the obviously gauge of reduction operation mechanism of two the switching-in spring chains 7 of being in tilted layout, 7 ', designs the operating mechanism of compact.
In structure as shown in Figure 4, in order to ensure not relatively move when operation after spring section module M2 and running part module M1 are totally connected, connecting portion is designed with stop bit shoulder 17.After totally connecting, the pressure of connecting bolt directly acts on stop bit shoulder 17, in the time of operation, the pulling force of chain is also directly delivered on stop bit shoulder 1, the direction of these active forces is all that spring section module M2 and running part module M1 are more securely linked together, as long as stop bit shoulder 17 does not damage, above-mentioned two parts just do not have and relatively move.And traditional plane syndeton is stressed large and there are vibrations in the situation that, be easy to occur relative displacement, finally make connecting bolt bear shearing force, long period of operation can be cut off bolt, and operating mechanism was thoroughly lost efficacy.
