Abstract
The utility model provides an operation mechanism of a circuit breaker, which consists of an energy storing device and an opening-closing device. The energy storing device is communicated with the opening-closing device through a communicating mechanism. A first class trip is arranged on the opening-closing device. The operating mechanism dispenses with a complex tripping device, reduces parts of the mechanism, lowers probability of failure and improves the mechanical service life of the mechanism.
Description
Technical field
The utility model relates to a kind of circuit breaker, is specifically related to the operating mechanism of the superior circuit breaker of a kind of opening performance.
Background technology
Like product mechanism complexity in the market, mechanical endurance is low.
The utility model content
Task of the present utility model is to provide a kind of operating mechanism of circuit breaker.
In order to solve above technical problem, the operating mechanism of a kind of circuit breaker of the present utility model, be made of energy storage device and divide-shut brake device, described energy storage device and divide-shut brake device are communicated with by means of communication, it is characterized in that: described divide-shut brake device is provided with one-level and threads off.
Described one-level is threaded off to the output connecting rod is provided with semiaxis, and the afterbody of combined floodgate fanning strip is bearing on the semiaxis and constitutes.
The advantage of above structure is: saved the numerous and diverse trip gear of operating mechanism in the past, mechanism's parts are reduced, the probability that then breaks down reduces, and has improved the mechanical endurance of mechanism.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in the figure, the divide-shut brake device is provided with combined floodgate semiaxis 3, and combined floodgate semiaxis 3 is communicated with electromagnet, at the afterbody of combined floodgate semiaxis 3 upper support combined floodgate fanning strips 2, described combined floodgate fanning strip 2 usefulness axle is fixed on the frame, above-mentioned combined floodgate semiaxis 3 and the combined floodgate fanning strip 2 synthetic tripping mechanisms that are called.
Be provided with output toggle arm 5 below tripping mechanism, install output shaft 4 at the centre bit of output toggle arm 5, described output toggle arm 5, output shaft 4 all are connected with combined floodgate connecting lever 6.Below combined floodgate connecting lever 6, be provided with separating brake semiaxis 8, tripping electromagnet, separating brake fanning strip 7 and splitting lock cushioning device 9, being connected of described separating brake semiaxis 8, tripping electromagnet and separating brake fanning strip 7 is identical with the annexation of above-mentioned tripping mechanism, described splitting lock cushioning device 9 is located at the afterbody of combined floodgate connecting lever 6, play the fixedly final position of combined floodgate connecting lever 6, the part of described combined floodgate connecting lever 6 partly contacts with the upper surface radian of separating brake fanning strip 7.
Connect separating brake big spring 11 and separating brake little spring 12 in described output connecting rod 1 lower end, the spring upper end is fixed on the support, and the lower end is a separating brake action savings energy by the connecting rod compressed energy-storage that makes progress when the breaker closing.
Energy storage device is made up of motor, deceleration device, energy storage connecting lever and switching-in spring, combined floodgate big spring 14 and combined floodgate little spring 15 upper ends are fixed on the support, combined floodgate pull bar 13 upper ends are connected with power transmission shaft 17, the upper end of described power transmission shaft 17 and cam 18 and energy storage axle 19, one side is connected with travelling gear 16, and travelling gear is connected with motor 24; The one side of described cam 18 involutes is provided with travel switch 25 towards combined floodgate connecting lever 6 on the frame above the cam 18.
In the separating brake energy storage operating state: energising was rotated after motor 24 was received the energy storage order, by gear drive, make energy storage axle 19 rotate close a floodgate large and small spring 14 and 15 energy storage, by cam 18 control gears 16 strokes, after energy storage put in place, cover broke away from engagement on the energy storage axle 19, and energy storage this moment axle 19 backs down travel switch 25, make motor 24 stalls from electrical equipment, by the inertia motion of motor 24, drive cam 18 and combined floodgate fanning strip 2 and snap onto on the combined floodgate semiaxis 3, make mechanism be in separating brake energy storage position.
In the closing operation operating state: combined floodgate release electromagnet 21 is being received the order back action of closing a floodgate, and combined floodgate semiaxis 3 clockwise directions are rotated, thereby makes energy storage keep removing, and energy storage axle 19 is clockwise rotated.Cam 18 on the energy storage axle 19 is along with the rotating drive output toggle arm 5 of energy storage axle 19, and drive output shaft 4 rotates together, by the outer connecting lever on tripping spring pull bar 10 and mechanism's take-off lever 1, the breaker body arc control device are passed in motion by output toggle arm outside the mechanism that is fixed on the output shaft 4 again, thereby make the contact closure in the arc control device, finish the three-phase feed motion.
In output toggle arm 5 rotating process, separating brake fanning strip 7 rotates along its track, and in the moment of making process, separating brake fanning strip 7 is snapped onto on the separating brake semiaxis 8, makes circuit breaker remain on "on" position.
Meanwhile, tripping spring 11 and 12 carries out energy storage, and after combined floodgate was finished, sluice separating spring also energy storage finished, and product possesses the separating brake condition.
When closing operation took place, energy storage motor had just been connected, energy storage again in 15s immediately.At this moment, mechanism is in the energy storage position of closing a floodgate.
In the sub-switching operation operating state:
Separating brake release electromagnet 21 making and close a floodgate to keep removing after receiving the separating brake order, and tripping spring 11 and 12 releases energy, and contact in the arc control device is being with by mechanism's output connecting rod 5 is moved to the separating brake position.
The kinetic energy of last separating brake motion is absorbed by splitting lock cushioning device 9 by interior output toggle arm.The splitting lock cushioning device also plays the function of stopping the separating brake motion at last.Simultaneously, deciliter direction board points to the separating brake position.
Claims (2)
1, a kind of operating mechanism of circuit breaker is made of energy storage device and divide-shut brake device, and described energy storage device and divide-shut brake device are communicated with by means of communication, it is characterized in that: described divide-shut brake device is provided with one-level and threads off.
2, the operating mechanism of a kind of circuit breaker according to claim 1 is characterized in that: described one-level is threaded off to the output connecting rod is provided with semiaxis, and the afterbody of combined floodgate fanning strip is bearing on the semiaxis and constitutes.
