Abstract
The utility model discloses a self-force-adjustable breaker automatic switch-on-off transmission mechanism, and belongs to the technical field of breakers. The transmission mechanism comprises a motor and a handle sliding groove which are arranged on a main body of a breaker. The transmission mechanism is characterized in that a motor shaft of the motor is matchedly connected with one end of a connecting lever, the other end of the connecting lever is matchedly connected with a steel plate, the other end of the steel plate is elastically and matchedly connected with a handle through a spring, and the handle is arranged in the handle siding groove. By employing the self-force-adjustable breaker automatic switch-on-off transmission mechanism, during a transmission process of the mechanism, the force driving the whole mechanism is kept by the steel plate; and during a rotating process in the clockwise direction, by utilizing the elastic characteristic of the spring, the force which the motor passes to the handle is adjusted by the addition of the spring, and the friction force of the handle moving leftward and rightward in the handle sliding groove can be adjusted, so that the firmness of the handle is ensured. The transmission mechanism is convenient and simple to operate, is safer and more reliable, and the probability that the breaker is damaged is greatly reduced.
Description
Technical field
The utility model belongs to breaker technical field, is specially a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power.
Background technology
At present, the mode that while putting into operation circuit-breaker switching on-off in electrical network, transmission mechanism adopts is by the driven by motor connecting lever, make connecting lever connect one of steel plate, the steel plate other end pulls handle, when circuit breaker sends the divide-shut brake indication, mechanism's work, electric machine rotation, thereby drive connecting lever and promote steel plate, and the steel plate strip fixed handle completes breaking-closing operating.In whole transmission mechanism, steel plate is the connector of motor, connecting lever, handle, although steel plate can rotate with handle, but because material steel hardness own is harder, power is soft not, again can't self-control, can only pull handle by rigidity, due to being rigidly connected of whole transmission mechanism, easily cause when carrying out the separating brake instruction, separating brake is not in place or when carrying out reclosing command, close a floodgate not in place, also can cause simultaneously the handle fracture, circuit breaker can't be worked, thereby power consumer safety utilization of electric power and equipment property are caused damage.
The utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to design the technical scheme that a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power is provided, its function admirable, the fail safe that has greatly improved circuit breaker, practicality.
Described a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, comprise the motor, the handle runner that are arranged on breaker body, the motor shaft and connecting lever one end that it is characterized in that motor are connected, the connecting lever other end and steel plate are connected, the steel plate other end is connected by spring and handle elastic, and handle is arranged in handle runner.
Described a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, is characterized in that motor shaft and connecting lever are connected by screw A.
Described a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, is characterized in that connecting lever and steel plate are connected by screw B.
Described a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, is characterized in that steel plate and spring are connected by screw C.
Described a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, is characterized in that spring and handle are connected by screw D.
Above-mentioned a kind of automatic opening-closing transmission mechanism of circuit breaker that can self-tune power, simple in structure, rationally, in mechanism's rotation process, both allowed steel plate keep driving the dynamics of whole mechanism, again by increasing a spring, the advantage of utilizing spring can stretch and shrink, in rotation process, regulating the dynamics that motor is passed to handle along clockwise direction, the friction dynamics also can regulating handle moved left and right at handle runner, when the dynamics need are large, spring stretches, dynamics need hour, spring contraction, thereby guaranteed to adopt the fastness of dielectric resin material handle, and it is not easily broken, this mechanism operation is convenient and simple, and safety and reliability, has greatly lowered the spoilage of circuit breaker.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is in "on" position;
Fig. 2 is the structural representation that the utility model is in gate-dividing state;
In figure: 1-motor, 2-motor shaft, 3a-screw A, 3b-screw B, 3c-screw C, 3d-screw D, 4-connecting lever, 5-steel plate, 6-spring, 7-handle, 8-handle runner, 9-breaker body.
Embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in the figure, this can self-tune power the automatic opening-closing transmission mechanism of circuit breaker, comprise the motor 1, the handle runner 8 that are arranged on breaker body 9, motor shaft 2 and connecting lever 4 one ends of motor 1 are connected, connecting lever 4 other ends and steel plate 5 are connected, steel plate 5 other ends are connected with handle 7 resilient engagement by spring 6, and handle 7 is arranged in handle runner 8.
Motor shaft 2 is connected by screw A3a with connecting lever 4, and connecting lever 4 is connected by screw B3b with steel plate 5, and steel plate 5 is connected by screw C3c with spring 6, and spring 6 is connected by screw D3d with handle 7.The number of turns of spring 6 and diameter are selected according to the size of circuit breaker, and the rated current of circuit breaker is larger, and the number of turns of leaf spring is more, diameter is larger; Otherwise the number of turns of spring 6 less, diameter is less.
Circuit breaker becomes the process of gate-dividing state from "on" position, motor 1 rotates with connecting lever 4, steel plate 5, spring 6, handle 7 and rotates along clockwise direction together, in rotation process, both allowed steel plate 5 keep driving the dynamics of whole mechanism, again by increasing a spring 6, the advantage of utilizing spring 6 can stretch and shrink, in rotation process, regulating the dynamics that motor 1 is passed to handle 7 along clockwise direction, also can 7 friction dynamics that move left and right in handle runner 8 of regulating handle, when the dynamics need were large, spring 6 stretched; Dynamics needs hour, and spring 6 shrinks, and makes its safe and reliable gate-dividing state that turns to, and has also guaranteed to adopt the fastness of dielectric resin material handle 7, and in long-term divide-shut brake process, handle 7 can not be pulled off firmly yet, has improved the useful life of circuit breaker.
