Abstract
The utility model discloses a high-voltage breaker spring operating mechanism, which comprises a motor and an output shaft for driving a breaker disconnecting switch. A driven crank arm is fixed onto the output shaft, a main crank arm connected with the motor through a main crank arm driving device is rotatably sleeved at the position of the output shaft close to the driven crank arm, the main crank arm is connected with a switching closing spring, and striking bosses mutually blocking at a meeting position in a rotating direction on the output shaft are respectively in projecting arrangement at opposite ends of the main crank arm and the driven crank arm. The spring operating mechanism drives the output shaft to rotate to realize switching closing operation of the disconnecting switch by employing the striking boss on the main crank arm to strike the striking boss on the driven crank arm, thereby overcoming the drawback of low starting speed of a device moving contact.
Description
Technical field
The utility model relates to high voltage electric equipment, in particular for the spring operating mechanism of control high-voltage circuit breaker, closing operation.
Background technology
At present, the spring operating mechanism that primary cut-out adopted in the high voltage electric equipment, as Fig. 7～shown in Figure 10, motor 5 is through roller gear 3, roller gear 4, worm screw 2 drives worm gear 1 and rotates, worm gear 1 rotates and is assemblied on the output shaft 7, be rotatably equipped with on the output shaft 7 with worm gear 1 on the main connecting lever 11 that on direction of rotation, is linked of cam path, side near main connecting lever 11 on the output shaft 7 is fixed with driven connecting lever 12, the connecting lever end of main connecting lever 11 is hinged on an end of divide-shut brake spring 6 by driven bearing pin 13, and driven connecting lever 12 is suitable, rotate counterclockwise the corresponding respectively oil bumper 8 that only cooperates with the top of driven connecting lever 12 that is provided with in two limit positions place of stroke.Existing spring operating mechanism is when work, motor 5 drives worm gears 1 and main connecting lever 11 and rotates and make 6 energy storage of divide-shut brake spring, when releasing energy, spring 6 clashes into the connecting lever end of driven connecting lever 12 by the driven bearing pin on the main connecting lever 11 13, thereby drive driven connecting lever 12 and output shaft 7 rotations, realize that output shaft 7 drives isolating switch and closes a floodgate fast or separating brake, when electronic sub-switching operation, contactor control motor 5 energising clockwise directions rotate, by roller gear 3,4 and worm screw 2 drive worm gears 1 clockwise direction and rotate, worm gear 1 and then the driven bearing pin 13 that drives on the main connecting lever 12 rotate around output shaft 7,6 energy storage of compression divide-shut brake spring.Because of worm gear 1 and main connecting lever 11 are placed on the output shaft 7, output shaft 7 does not rotate during energy storage, when main connecting lever 11 goes to the fairlead of divide-shut brake spring 6 in line, spring energy-storage reaches maximum, after being rotated further the dead point, spring releases energy, and driven bearing pin 13 bumps also drive driven connecting lever 12 and output shaft 7 quick rotation, and output shaft 7 drives the isolating switch quick acting switching-off through the connecting lever linkage; When closing operation, the motion process of each several part is identical with electronic separating brake, but the direction of motion is opposite.
In the existing spring operating mechanism, divide-shut brake is to move driven connecting lever 12 by the driven bearing pin 13 on the main connecting lever 11 to move together.If requiring the output shaft output angle of mechanism is 80 degree, can draw (referring to Fig. 8 by calculating, Fig. 9): driven connecting lever self angle is 110 degree, the fairlead energy storage that so main connecting lever 11 and spring are connected is in line the time, this moment, we were called the dead-centre position, at this moment the driven bearing pin on the main connecting lever 11 of dead-centre position 13 has only 10 degree with the stress surface angle of driven connecting lever, add the diameter of driven bearing pin 13, after just meaning that driven bearing pin 13 is crossed the dead-centre position, will move driven connecting lever 12 when impact less than 10 is spent under the effect of spring moves together, because rotational angle is limited, the raising of the speed of driven bearing pin 13 from zero start to when bump is also few, thereby directly causes the moving contact toggle speed of driven connecting lever 12 and institute's driving arrangement slow.When therefore existing operating mechanism is applied to output angle requirement small device, problem is little, can satisfy instructions for use fully, but for the equipment that has big output angle to require, tend to because driven connecting lever 12 staring torques are too small, cause that product performance is unstable or defective.
The utility model content
The impact structure that the purpose of this utility model is to provide a kind of main connecting lever from the dead point to the bigger high-voltage breaker spring operating mechanism of scope of design of the projected angle of impact of driven connecting lever bump, to solve the too small problem of existing high-voltage breaker spring operating mechanism staring torque in the background technology.
The technical solution of the utility model is: a kind of high-voltage breaker spring operating mechanism, comprise motor and the output shaft that is used to drive disconnector, be fixed with driven connecting lever on the described output shaft, going back turning set on the output shaft is equipped with and the main connecting lever of described motor by main connecting lever transmission device interlock, be connected with the divide-shut brake spring on the described main connecting lever, the relative respectively bump boss that on the output shaft direction of rotation, stops mutually that convexes with on the opposite end of described main connecting lever and driven connecting lever in the place of catering to.
Described main connecting lever transmission device comprises the gear train that is in transmission connection with the output of described motor, the worm screw that is in transmission connection with the output shaft of gear train, the worm gear that is connected with worm-drive, and described worm gear turning set is contained on the output shaft and with main connecting lever and is linked on direction of rotation.
Card is furnished with and is used to prevent the locking key of driven connecting lever with the friction campaign of main connecting lever between described main connecting lever and the driven connecting lever corresponding end, and locking key one end rotates and is assemblied on the casing of spring operating mechanism, and the groove button of corresponding setting is joined on the other end and the driven connecting lever.
Spring operating mechanism of the present utility model is to main connecting lever, impact structure between driven connecting lever has carried out design improvement, increased the bump boss at the place of catering to of both corresponding end, cancelled the structure that driven bearing pin hits an end of driven connecting lever, when actual design is used, can be according to the required angle that charges and attacks moving driven connecting lever under the main connecting lever, can calculate the angle that staggers of the bump boss on main connecting lever and the driven connecting lever, the speed that so just can realize under the main connecting lever dashing when clashing into is carried to higher from zero, the bump boss that clashes on the driven connecting lever by the bump boss drives the branch that output shaft is realized isolating switch, closing operation has solved equipment moving contact toggle speed shortcoming slowly.
