According to the limiting buffer device with the structure, and the alternating-current high-voltage vacuum circuit breaker mechanism with the limiting buffer device, the maximum rotation angle of a main shaft in the process of switching-on operation can be controlled only through control over the relative position relation between the limiting buffer device and a switching-on limiting idler wheel, and the overshoot phenomenon of the alternating-current high-voltage vacuum circuit breaker mechanism can be prevented; due to the fact that the rubber pads on the limiting buffer device play a role in buffering overshoot impact, the mechanical property of an alternating-current high-voltage vacuum circuit breaker is ensured.
Description
Technical field
The AC high voltage vacuum breaker mechanism that the present invention relates to a kind of limit damper and 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.
Summary of the invention
Technical problem to be solved by this invention 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 limits the roller maximum rotation angle that Liao Yu mechanism main shaft rotates simultaneously, has prevented mechanism's overshoot.
Technical scheme of the present invention 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.
