Abstract
The invention discloses a kind of AC high voltage vacuum opens circuit, comprise breaker body framework (4), mechanism's main shaft (8) and be arranged on the combined floodgate limited roller (7) on mechanism's main shaft (8), on described mechanism's main shaft (8), mechanism's power output part (9) is also installed, limit damper (6) is fixedly mounted on breaker body framework (4). There is the Gai Zhong AC high voltage vacuum breaker mechanism of said structure 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 in the time of closing operation, thereby anti-locking mechanism overshoot, rubber blanket on limit damper has cushioning effect to overshoot impulsive force, has ensured breaker mechanical performance.
Description
Technical field
The present invention relates to a kind of AC high voltage vacuum breaker mechanism.
Background technology
Voltage vacuum circuit breaker mechanism, can as indispensable major control in power system and protection equipmentHigh by property, cut-off that capacity is large, the time between overhauls(TBO) long, pollution-free, without explosion danger, applicable frequent operation etc.Series advantage, has all obtained more and more in every field such as power industry, industrial and mining enterprises, railway transportationsApplication widely. Circuit breaker operation mechanism is AC high voltage vacuum breaker mechanism important component part, and it is movingThe reliability of doing and the mechanical property parameter of motion are directly connected to the safety of breaker operation.
In the existing design of operating mechanism of AC high voltage vacuum breaker mechanism, are all lean on vacuum interrupter quietThe insulated tension pole of contact and movable contact head end is spacing as closing a floodgate, and insulated tension pole inside is equipped with spring and is used for cushioning disconnectedThe impulsive force of road device making 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 machineStructure unit failure, brings difficulty to production process.
At present, prevent in process of production closing process phenomenon, often vacuum interrupter movable contact head end absolutelyEdge pull bar power is adjusted to upper range, but causes like this pressure of arc-chutes excessive, affects the use of arc-chutesLife-span.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of interchange high for problems of the prior artPress vacuum circuit breaker mechanism, its objective is in the time of breaker mechanism closing process to there is the spacing of pooling featureBuffer unit has limited the roller maximum rotation angle of simultaneously rotating with mechanism main shaft, has prevented mechanism's overshoot.
Mechanism of technical scheme Shi Gaizhong AC high voltage vacuum breaker of the present invention mechanism, described ac high-voltageVacuum circuit breaker mechanism mechanism comprises breaker body framework, mechanism's main shaft and is arranged on mechanism's main shaftCombined floodgate limited roller, is also provided with mechanism's power output part on described mechanism's main shaft, and described is spacing slowFlushing device is fixedly mounted on breaker body framework; Limit damper comprises base plate, rubber blanket and steel plate,Described rubber blanket and steel plate are alternately arranged in parallel successively, and described base plate is L-type structure, its of L-type base plateIn a limit be arranged on rubber blanket; Described rubber blanket and steel plate have respectively two-layer, described L-type base plateOne of them limit be arranged on outermost rubber blanket.
Described combined floodgate limited roller keeps synchronizeing with the action of mechanism main shaft.
There is the Gai Zhong AC high voltage vacuum breaker mechanism of said structure as long as control limit damper and closeRelative position between lock limited roller, just can control the maximum rotation angle of main shaft in the time of closing operation, fromAnd anti-locking mechanism overshoot, the rubber blanket on limit damper has cushioning effect to overshoot impulsive force, ensuresBreaker mechanical performance.

Rubber blanket 2 and steel plate 3 have respectively two-layer, LOne of them limit of type base plate 1 is arranged on outermost rubber blanket 2.
Fig. 2 is the structural representation with the AC high voltage vacuum breaker mechanism of limit damper. Fig. 3For the structural representation of the AC high voltage vacuum breaker mechanism with limit damper in gate-dividing state.AC high voltage vacuum breaker mechanism comprises breaker body framework 4, mechanism's main shaft 8 and is arranged on the master of mechanismCombined floodgate limited roller 7 on axle 8, combined floodgate limited roller 7 keeps synchronizeing with 8 actions of mechanism main shaft. DescribedMechanism's power output part 9 is also installed on mechanism's main shaft 8, and described limit damper 6 is fixedly mounted onOn breaker body framework 4, as long as control relative between limit damper 6 and combined floodgate limited roller 7Position, just can control the maximum rotation angle of main shaft in the time of closing operation.
Limit damper 6 is fixed on the breaker body framework 4 of installing, and combined floodgate limited roller 7 is installedOn mechanism's main shaft 8, keep synchronizeing with 8 actions of mechanism main shaft, mechanism's power output part 9 is assemblied in machineStructure main shaft 5, the holding member 5 that closes a floodgate after breaker mechanism closing operation can remain on "on" position by mechanism.
There is the Gai Zhong AC high voltage vacuum breaker mechanism of said structure as long as control limit damper and closeRelative position between lock limited roller, just can control the maximum rotation angle of main shaft in the time of closing operation, fromAnd anti-locking mechanism overshoot, the rubber blanket on limit damper has cushioning effect to overshoot impulsive force, ensuresBreaker mechanical performance.
