Abstract
The utility model relates to the technical field of vacuum circuit breakers, in particular to an interlocking mechanism of an inflatable cabinet type vacuum circuit breaker. The mechanism is provided with a rotating shaft and crank arms, wherein the rotating shaft is arranged on a circuit breaker case, and the crank arm I and the crank arm II are fixed at two ends of the rotating shaft. By mutual restrictive fit of the crank arms, a transmission rod and a connecting rod, interlocking of the circuit breaker is realized; and the mechanism meets the miniaturization requirement of an inflatable cabinet, and has the advantages of a few parts, simple structure and compact and attractive appearance.
Description
Technical field
The utility model relates to the vacuum circuit-breaker technical field, especially a kind of interlocking device of inflating cabinet type vacuum circuit-breaker.
Background technology
The electric misoperation of high-voltage switch gear causes the damage of power equipment easily, system blackout even initiation personal safety.Interlocking device's part of the cabinet type vacuum circuit-breaker of existing inflation is more, complex structure, and volume is bigger, need be arranged into outside the cabinet, influences outward appearance.
The utility model content
For the interlocking device's part that overcomes the cabinet type vacuum circuit-breaker of existing inflation more; Baroque shortcoming, the utility model provide a kind of interlocking device of inflating cabinet type vacuum circuit-breaker, not only satisfy the demand of inflation cabinet miniaturization; And simple in structure, simple appearance is attractive in appearance.
The utility model solves the technical scheme that its technical problem adopted: a kind of interlocking device of inflating cabinet type vacuum circuit-breaker has rotating shaft, connecting lever; Rotating shaft is contained on the circuit breaker cabinet, and the rotating shaft two ends are fixed with connecting lever one and connecting lever two, and connecting lever one other end is connected with drive link; Rotating shaft is rotated, and drive link extends downward combined floodgate semiaxis portion dress place through bent plate one guiding; Block the combined floodgate semiaxis, circuit breaker can not close a floodgate when a little; The rotating shaft other end is installed in the middle of the connecting lever two, and connecting lever 21 ends are connected with connecting rod, and connecting rod is through bent plate two guiding; Extend downward connecting lever three places, connecting lever three is fixed on the main shaft, is with stage clip on the connecting rod; Play reset response, when breaker closing, main shaft rotates; Connecting lever three is provided with flanging, blocks connecting rod and moves downwards, and rotating shaft this moment can not be rotated.
The beneficial effect of the utility model is, inflates employing the utility model interlocking device of cabinet type vacuum circuit-breaker, not only satisfy the demand of inflation cabinet miniaturization, and part is few, and simple in structure, simple appearance is attractive in appearance.
