[0039] The shaft in the closing shaft assembly 10 is machined to leave only half shaft material, when the closing coil acts or the closing button 13 is pressed, that is, the half shaft in the closing shaft assembly 10 will rotate counterclockwise (with Figure 4 and Figure 5If the original energy storage spring 7 releases, the roller 18 will be separated from the closing holding cam 16 and will not contact with it, the cam mechanism 17 rotates anticlockwise rapidly for a certain angle, the connecting rod 23 and the connecting rod 24 are connected by the pin shaft 7, the pin shaft 7 is installed with a bearing, the cam mechanism 17 will gradually increase the bearing from the lowest point to the highest point of the cam mechanism 17, thereby driving the connecting rod 23 to swing anticlockwise, the connecting rod 23 is connected with the driving shaft 4 through the V-shaped driving plate 32, the V-shaped driving plate 32 is also connected with the transmission plate 21, the driving shaft 4 rotates clockwise, which will push the vacuum bubble in the circuit breaker linearly by 18mm, at this time, the closing action is completed; at the same time, the transmission plate 21 rotates anticlockwise, the transmission plate 21 will compress the opening spring 8, when the opening spring 8 is compressed to 77.75mm, the opening spring 8 is fully energized for opening; in addition, at this time, the roller 26 will be tangent to the lower right end gap of the opening holding cam 19, the opening holding cam 19 will rotate clockwise for a certain angle and contact with the opening shaft assembly 15, finally, the roller 26, the opening holding cam 19 and the opening shaft assembly 15 will be stationary, ready for the next step of opening.
[0040] After the closing is completed, the opening spring 8 has been compressed and energized, the roller 26 contacts with the opening holding cam 19, and the opening holding cam 19 contacts with the opening shaft assembly 15, at this time, rotating the opening shaft assembly 15 clockwise, the opening spring 8 will rapidly release the energy of the spring, drive the V-shaped driving plate 32 to rotate clockwise, the transmission plate 21 will hit the buffer 20 to prevent the opening from rebounding too much, and the transmission plate 21 drives the driving shaft 4 to rotate anticlockwise, thereby pulling the vacuum bubble to complete the opening action; the connecting rod 23 and the connecting rod 24 correspondingly follow, the bearing on the pin shaft 7 rolls on the cam mechanism 17, and finally stops at the position as shown in Figure 4 .
[0041] How to realize the mechanical anti-jumping function:
[0042] When the closing button 13 is stuck, or after pressing the closing button 13, it is not accurately reset, or the closing coil does not accurately act, at this time, if the energy storage motor 5 starts, the energy storage spring 7 will continuously store energy, the cam mechanism 17 rotates anticlockwise according to the normal track, the three connecting rods (the connecting rod 25, the connecting rod 24 and the connecting rod 23) and the rollers 26 and 18 move according to the normal track, but at this time, the half shaft in the closing shaft assembly 10 does not block the closing holding cam 16 at the accurate position, as shown in Figure 5As shown, the cam mechanism 17 cannot stay in the energy storage position, and the energy storage spring 7 will release its energy quickly, and the roller 18 and the cam mechanism 17 will continue to rotate counterclockwise, and when the energy storage spring 7 is fully discharged, the split holding cam 16 keeps contact with the roller 26, and in fact, the circuit breaker mechanism has jumped through the closing state and is directly in the open position. In this way, the circuit breaker has completed the mechanical anti-jumping function.
[0043] Here, the focus is on the special structural design of the cam mechanism 17 in the circuit breaker mechanism, the closing holding cam 16, and the closing shaft assembly 10, which ensures that once the closing shaft assembly 10 is no longer in contact with the closing holding cam 16, the closing function cannot be achieved, and thus ensures that the circuit breaker is in the open state and cannot appear multiple "jump-closing" phenomena.
[0044] To verify the effectiveness of the described principles of the application, a self-made circuit breaker mechanism was tested for 10,000 times of mechanical characteristics and life (M2 level), and all parts of the mechanism were not damaged and lost functionality. At the same time, mechanical characteristic tests were also conducted, and the closing and opening speed, closing and opening travel, closing and opening synchronism, and opening rebound and other parameters were all within the specified range.
[0045] By simulating the closing shaft being stuck through artificial intervention, and then the circuit breaker mechanism stores energy through a large spring, although the cam mechanism 17 can still operate normally, the closing shaft assembly cannot stop the cam driving system, resulting in the circuit breaker mechanism being unable to complete closing. In this way, the special mechanism can ensure that it cannot jump and cycle.
[0046] The mechanical anti-jumping mechanism device has reasonable transmission layout, smooth spring operation, and small release impact; the compactly designed frame and cam mechanism have high reliability of mechanical transmission position, effectively prevent the occurrence of jumping, thereby improving the service life of the mechanism and the reliability of the circuit breaker, and ensuring the stability of the medium-voltage power system.
