This utility model discloses a limiting buffer device and an AC high voltage vacuum circuit breaker mechanism. The limiting buffer device comprises a baseplate (1), rubber mats (2) and steel plates (3). The rubber mats (2) and the steel plates are arranged alternatively in a parallel manner. The baseplate (1) is in an L-shaped structure; one side of the L-shaped baseplate (1) is installed on the rubber mat (2); the rubber mats (2) consist of two layers and the steel plates (2) consist of two layers; one side of the L-shaped baseplate is installed on the outmost rubber mat (2). The limiting buffer device and the AC high voltage vacuum circuit breaker mechanism can control the most rotation angle of a main shaft performing a closing operation by controlling the relative position between the limiting buffer device and the closing limiting roller so as to prevent overshooting of the mechanism. The rubber mats on the limiting buffer device have buffering effects on the shooting impact, so that the mechanical property of the circuit breaker can be guaranteed.
Description
Technical field
The utility model relates to a kind of limit damper and the AC high voltage vacuum breaker mechanism of this kind of limit damper is installed.
Background technology
Voltage vacuum circuit breaker mechanism is as indispensable major control in electric power system and protection equipment; reliability is high, cut-off that capacity is large, the time between overhauls(TBO) long, pollution-free, without explosion hazard, be applicable to the series of advantages such as frequent operation, in every field such as power industry, industrial and mining enterprises, railway transportations, all obtained application more and more widely.Circuit breaker operation mechanism is AC high voltage vacuum breaker mechanism important component part, and the mechanical property parameter of the reliability of its action and motion is directly connected to the safety of circuit breaker operation.
In the existing design of operating mechanism of AC high voltage vacuum breaker mechanism, be all spacing as closing a floodgate by the fixed contact of vacuum interrupter and the insulated tension pole of movable contact head end, insulated tension pole inside is equipped with spring and is used for cushioning the impulsive force of breaker closing process and the crimp force of the contact after combined floodgate is provided.Particularly, in production debug process, how closing speed is too fast, and breaker mechanism is easy to produce overshoot phenomenon, and overshoot easily causes breaker mechanism unit failure, to production process, brings difficulty.
At present, prevent in process of production closing process phenomenon, often the insulated tension pole power of vacuum interrupter movable contact head end is adjusted to upper range, but cause like this pressure of arc control device excessive, affect the useful life of arc control device.
Utility model content
Technical problem to be solved in the utility model is the AC high voltage vacuum breaker mechanism that a kind of limit damper is provided and this kind of limit damper is installed for problems of the prior art, its objective is when breaker mechanism closing process, the limit damper with pooling feature has limited the roller maximum rotation angle of simultaneously rotating with mechanism main shaft, has prevented mechanism's overshoot.
The technical solution of the utility model is that this kind of limit damper comprises base plate, rubber blanket and steel plate, and described rubber blanket and steel plate are alternately arranged in parallel successively, and described base plate is L-type structure, and one of them limit of L-type base plate is arranged on rubber blanket.
Described rubber blanket and steel plate have respectively one of them limit of two-layer, described L-type base plate to be arranged on outermost rubber blanket.
A kind of mechanism of AC high voltage vacuum breaker mechanism that above-mentioned limit damper is installed, described mechanism of AC high voltage vacuum breaker mechanism comprises breaker body framework, mechanism's main shaft and is arranged on the combined floodgate limited roller on mechanism's main shaft, on described mechanism's main shaft, mechanism's power output part is also installed, described limit damper is fixedly mounted on breaker body framework.
Described combined floodgate limited roller keeps synchronizeing with the action of mechanism main shaft.
There is this kind of limit damper of said structure and the AC high voltage vacuum breaker mechanism of this kind of limit damper is installed as long as control the relative position between limit damper and combined floodgate limited roller, just can control the maximum rotation angle of main shaft when closing operation, thereby anti-locking mechanism overshoot, rubber blanket on limit damper has cushioning effect to overshoot impulsive force, has ensured circuit breaker mechanical performance.
