Abstract
The utility model provides a position device was prevented to high voltage circuit breaker branch, combined floodgate. It includes spacing turning arm and locating pin, wherein the back tip of spacing turning arm utilizes the pivot to fix the opposite position of transmission turning arm in the transmission case, and the front portion is formed with an elongated slot, the one end of locating pin is fixed on the outer end upper portion of transmission turning arm, and insert in the elongated slot of spacing turning arm the outside. The utility model provides a position device was prevented to high voltage circuit breaker branch, combined floodgate has following beneficial effect: compare with the stop device of other structures, this structure is more simple, the stop device of other structures generally install in the mechanism with the middle transmission link, the separating brake arranges separately with the spacing needs of combined floodgate that spacing an organic whole of divide -shut brake can be realized to this device, has reduced intermediate link in addition, the good reliability, has improved product production efficiency, sparingly manufacturing cost at time of save material and debugging.
Description
Technical field
The utility model belongs to electrical facility technical field, particularly relates to a kind of high-voltage circuit breaker, close a floodgate anti-position device excessively.
Background technology
Circuit breaker be a kind of can close, carry and cut-off the electric current under normal loop condition and can close, the switching device of carrying and the electric current under cut-offfing abnormal loop condition in official hour, mainly comprise transmission case and be arranged on the parts such as transmission crank arm, moving contact, fixed contact, touch base, spring touch finger, moving contact driving cylinder in transmission case.Circuit breaker point, closing operation time, regulation have fixing divide-shut brake position.Kinetic characteristic, the Mechanical Reliability of divide-shut brake position and circuit breaker are closely bound up, therefore must ensure its correctness.The phenomenon crossing position if there is divide-shut brake will cause serious consequence, position of wherein closing a floodgate can cause moving contact and other parts collide and cause mechanical damage, thus impact insulation and electric property, or cause the parts such as moving contact guide ring, spring touch finger to deviate from from holddown groove, when carrying out sub-switching operation in this case, the moving components such as moving contact driving cylinder can be stuck by the part deviate from, cause circuit breaker cannot separating brake, drop-out current failure even can cause circuit breaker to be blasted.Separating brake is crossed position and then can be caused, between moving contact and touch base, fierce mechanical collision occurs, and causes driving member to rupture, or damages other parts, causes circuit breaker cannot normal running, and result has a strong impact on the reliability of circuit breaker.The method that below 110kV grade products limits divide-shut brake position is inner at this device or drive disk assembly installs the rigid stopping means of machinery additional, the phenomenon that divide-shut brake crosses position is prevented with this, but the mechanism of more than 110kV product and body often split transport, the situation of divide-shut brake change in location is easily there is afterwards in body in the locking of releasing mechanism, if do not have reliable restraint device to occur that divide-shut brake crosses the phenomenon of position by being easy to, bring great hidden danger to product.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of high-voltage circuit breaker, close a floodgate anti-position device excessively.
In order to achieve the above object, the utility model provides high-voltage circuit breaker, the anti-position device crossed that closes a floodgate comprise spacing connecting lever and alignment pin; Wherein the rearward end of spacing connecting lever utilizes rotating shaft to be fixed on the opposite side of transmission crank arm in transmission case, and front portion is formed with an elongated slot; One end of alignment pin is fixed on the top, outer end of transmission crank arm, and outside is inserted in the elongated slot of spacing connecting lever.
The angle α that described alignment pin is in when closing a floodgate restriction extreme higher position and separating brake restriction extreme lower position and between horizontal line is 36 °.
The high-voltage circuit breaker that the utility model provides, the anti-position device of crossing that closes a floodgate have following beneficial effect: compared with the stopping means of other structures, this structure is more simple, the stopping means of other structures is generally arranged in mechanism and intermediate transmission link, and the spacing needs of separating brake and combined floodgate are arranged apart, this device can realize the spacing one of divide-shut brake, decreases intermediate link, good reliability, save the time of material and debugging, improve production efficiency, save production cost.
Accompanying drawing explanation
The high-voltage circuit breaker that Fig. 1 provides for the utility model, the anti-position device of crossing that closes a floodgate are in structural representation when closing a floodgate restriction extreme higher position.
The high-voltage circuit breaker that Fig. 2 provides for the utility model, close a floodgate and anti-ly cross structural representation when position device is in separating brake restriction extreme lower position.
Embodiment
The high-voltage circuit breaker provided the utility model below in conjunction with the drawings and specific embodiments, the anti-position device of crossing that closes a floodgate are described in detail.
As shown in Fig. 1-Fig. 2, the high-voltage circuit breaker that the utility model provides, the anti-position device of crossing that closes a floodgate comprise spacing connecting lever 1 and alignment pin 2; Wherein the rearward end of spacing connecting lever 1 utilizes rotating shaft 3 to be fixed on the opposite side of transmission crank arm 4 in transmission case, and front portion is formed with an elongated slot 5; One end of alignment pin 2 is fixed on the top, outer end of transmission crank arm 4, and outside is inserted in the elongated slot 5 of spacing connecting lever 1.
The angle α that described alignment pin 2 is in when closing a floodgate restriction extreme higher position and separating brake restriction extreme lower position and between horizontal line is 36 °.
The high-voltage circuit breaker now the utility model provided, anti-position device using method of crossing of closing a floodgate is described below: when primary cut-out carries out sub-switching operation, the outer end of its upper driving connecting lever 4 rotates clockwise from the closing position in Fig. 1, in the process, the alignment pin 2 be connected in transmission crank arm 4 slides in the elongated slot 5 on spacing connecting lever 1, the outer end of spacing connecting lever 1 is driven to rotate counterclockwise thus, during closing position shown in Fig. 2 to be achieved, by the restriction of elongated slot 5, the outer end of spacing connecting lever 1 can not be rotated further again, thus separating brake crosses the problem of position can to prevent circuit breaker from occurring.Closing operation is contrary with said process.
