Description
The utility model belongs to the high-voltage switch gear field of electric power system, is particularly suitable for 110 kilovolts and above high-pressure vacuum breaker product.
The primary cut-out of present 110 kilovolts and above electric pressure adopts sulphur hexafluoride as the arc extinguishing dielectric mostly, with vacuum as the circuit breaker of arc extinguishing means then because of technical difficulty be only limited to greatly in the pressure scope.But vacuum circuit-breaker is lower than the cost of sulfur hexafluoride breaker, and operation and maintenance is convenient, thereby causes the manufacturing attention of domestic high-voltage switch gear.
The design's purpose is to solve the series of technical of being brought when high-pressure vacuum breaker adopts other circuit breaker traditional structures, and not parallel as contact weight and the elongated contact contact-making surface that causes of conducting rod, transmission efficiency is not high, and arcing is serious or the like.Thereby, operation and maintenance easy high-pressure vacuum breaker product low for development cost creates conditions.
The design adopts three-phase packing, every phase double break form, two operating mechanisms that structure is identical place A and B to reach mutually between B and the C phase respectively, the change that drives each phase actuation mechanism that direct transfers, realize that every phase double break mouth is closing of the indoor dynamic and static contact of vacuum extinction or divides that all there is insulated porcelain sleeve each fracture outside.Different with existing circuit breaker is: each vacuum interrupter is perpendicular to the ground, two vacuum interrupters of every phase are on its change direct transfers two ends, the actuation mechanism case left and right sides, the configuration of formation U-shaped, correspondingly, the change of the every phase actuation mechanism that direct transfers adopts double rocking lever double crank slide block structure, promptly be rotationally connected successively and formed by a main shaft connecting lever, two master connecting-rod, two driven shaft connecting lever, two follower link, wherein the output shaft of main shaft connecting lever and operating mechanism is rotationally connected, and two follower link and fracture insulated tension pole are rotationally connected.Like this, just form two operating mechanisms and drive three changes situation of actuation mechanism that direct transfers, as long as suitably adjust the operating mechanism position, just can guarantee three straightening mechanisms synchronously with effect.
For thrust that latter two contact that closes a floodgate is provided with the arc time when shortening separating brake, each insulated tension pole end can be established the contact stage clip mechanism of following structure: ladder tubular connector cover is connected in the insulated tension pole end, pin is inserted in connector circular hole, cylinder briquetting circular hole and the tubular slide block slotted hole, the briquetting roof pressure the spring in the slide block, slide block is connected with moving conductive rod by bolt, and slide block can slide in guide pin bushing.The stop of combined floodgate rear slider, the continuation of insulated tension pole up (being overtravel) can make pin along moving on the slide block slotted hole, thereby make the briquetting holddown spring, form the thrust to contact.
More than She Ji main feature is:
Every phase double break mouth is got the U-shaped configuration, be that vacuum interrupter is perpendicular to the ground, heavy, the long stressed bad problem of being brought of conducting rod of vacuum interrupter high pressure specification contact when having avoided the configuration of common employing Y shape or T shape, make conducting rod be in the optimum state of no bending moment, guaranteed the parallel of dynamic and static contact contact-making surface, helped alleviating contact arcing infringement and increase the service life; The change of double rocking lever double crank slide block structure direct transfer actuation mechanism as calculated and the test, transmission efficiency reaches more than 80%, be higher than the direct transfer transmission efficiency of moving device of changes such as general elliptical mechanism, offset conn rod mechanism, contact stage clip mechanism not only provides the thrust after contact closes a floodgate, and rapid dialysis can be made the contact separating brake again by the elastic force that pressing spring is put aside the time, shortened the arc time.
These characteristics have overcome the deficiency of configurations such as Y shape, T shape effectively, high-pressure vacuum breaker can reliablely and stablely be worked under stressed good state, thereby be that cost is low, the production of the High Voltage Vacuum Circuit Breakers of convenient operating maintenance is laid a good foundation.
