Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of low-voltage electrical apparatus, and particularly relates to a switching device operating system conversion device, especially suitable for a dual power automatic transfer switch. BACKGROUND

[0002] Dual power automatic transfer switches are widely used in modern power transmission and distribution line systems, especially in places such as hospitals, intelligent buildings, data centers, power plants, banks, and important infrastructure that require continuous power supply. During the operation of a dual power automatic transfer switch, its reliability and stability are directly related to the continuous power output of the power transmission and distribution line. Dual power automatic transfer switches have two-position automatic transfer switches and three-position automatic transfer switches. Two-position automatic transfer switches switch between the two states of the normal side power being on (with the standby side power being off) and the standby side power being on (with the normal side power being off), achieving continuous, stable, and reliable power output of the power transmission and distribution line. In addition to the working states of two-position automatic transfer switches, three-position automatic transfer switches can also achieve the state of the normal side power and the standby side power being off simultaneously (i.e., the double-off state) and the locking of the off state.

[0003] The operating mechanism is the core component of a dual power automatic transfer switch, providing the kinetic energy for the position switching of the automatic transfer switch and connecting the output part to the contact system of the automatic transfer switch to switch between the on positions of the normal side power and the standby side power. The operating mechanism of a two-position automatic transfer switch has two states, corresponding to the on positions of the normal side power and the standby side power, respectively. The operating system of a three-position automatic transfer switch has three states, corresponding to the on positions of the normal side power, the standby side power, and the double-off position, respectively. However, the existing three-position automatic transfer switches have separate locking mechanisms for the normal side, the standby side, and the double-off position, and the three locking mechanisms do not interfere with each other, which can easily lead to the locking of only one position and the lack of locking of the other position, resulting in safety accidents due to misoperation. On the other hand, the existing dual power automatic transfer switches have a double-main shaft structure, which cannot meet the requirements of same-side wiring. In addition, the existing dual power automatic transfer switches require manual operation when manually switching on and off, which can lead to the failure to complete the switching on and off of the switch due to insufficient manpower or the damage of the switch due to excessive manpower. SUMMARY

[0004] The present application aims at the defects of the existing double power automatic transfer switch operating mechanism, and provides a switching device operating system conversion device, which can manually realize stable and reliable switching of the double power automatic transfer switch among three states of only normal side power tripping, only standby side power tripping and normal side power and standby side power tripping at the same time.

As shown in the attached Figure 9 and 10As shown, the corresponding swing lever 5, 5' includes an upper lever 501, 501' and a lower lever 502, 502', the upper lever 501, 501' is pivoted with the lower lever 502, 502' by a pivot shaft 504, 504', and can be limited in stroke by a limiting shaft 502a, 502a' on the lower lever 502, 502' which is located in a limiting hole 501c, 501c' on the upper lever 501, 501'.

[0054] The lower lever 502, 502' is rotatably mounted on a swing lever mounting shaft 106, 106' on the front surface of the bracket 1, and can be limited in stroke by a swing lever limiting shaft 107, 107' on the bracket 1 which is located in a limiting hole 502c, 502c' on the lower lever 502, 502'.

[0055] In this embodiment, when the standby side power supply is in the closed-on state, the position state of each component is as follows: the turnover lever A1' is located at its maximum clockwise rotation position, and the turnover lever A1' is connected to the turnover lever A1 through the slide plate 2, so that the turnover lever A1 is located at its maximum clockwise rotation position; the dialing lever 4 on the commonly used side is in contact with the slide plate dialing shaft 2b of the slide plate 2 on the left side wall of the slide plate linkage hole 403 under the action of the dialing lever return spring 4a', and the dialing lever 4' on the standby side is in contact with the linkage part slide plate dialing shaft 2 of the slide plate on the right side wall of the slide plate linkage hole 403' under the action of the dialing lever return spring 4a as shown in the accompanying drawings. Figure 13

[0056] ​The spare side rotating lever C' is at the maximum position of counterclockwise rotation, the lower lever connecting part C2' connects the connecting column 502b' on the lower lever 502', and the spare side swing lever 5' is at the maximum position of counterclockwise rotation. At this time, due to the action of the swing lever reset spring 503', the right part of the positioning hole 501c' of the upper lever 501' is in contact with the positioning shaft 502a', and the blocking protrusion 501a' on the upper lever 501' blocks the shifting hole 405 of the shifting lever 4 on the normal side. At this time, the handle 6 cannot be inserted into the shifting hole 405 of the shifting lever 4 to operate as shown in FIG. 8. Figure 13 and 14 as shown.

[0057] The rotating lever C is at the maximum position of counterclockwise rotation, and the lower lever connecting part C2 is not in contact with the connecting column 502b on the lower lever 502. At this time, due to the action of the swing lever reset spring 503, the left part of the positioning hole 501c of the upper lever 501 is in contact with the positioning shaft 502a, and the swing lever 5 is at the maximum position of counterclockwise rotation. At this time, the blocking protrusion 501a on the upper lever 501 does not block the shifting hole 405' of the shifting lever 4' on the spare side, and the handle 6' can be inserted into the shifting hole 405' of the shifting lever 4' to operate as shown in FIG. 7. Figure 13 and 14 as shown.

[0058] When switching from the spare side power closing connection state to the double split state: insert the handle 6' into the shifting hole 405' of the shifting lever 4', and pull it counterclockwise. At this time, the right side wall of the sliding plate connecting hole 403' of the shifting lever 4' connects the sliding plate shifting shaft 2b of the sliding plate 2 and makes the sliding plate 2 move to the left. While the sliding plate 2 moves to the left, it connects the flip levers A1 and A1' and makes them rotate counterclockwise at the same time. At the same time, when the sliding plate 2 moves to the left, it connects the sliding plate connecting hole 403 of the shifting lever 4 through the sliding plate shifting shaft 2b, and overcomes the spring force of the shifting lever reset spring 4a', so that the shifting lever 4 rotates counterclockwise around the shifting lever mounting shaft 110.

[0059] After the handle 6' connects the spare side shifting lever 4' to the position, the operating mechanism performs the opening action. During the opening process, the rotating levers C and C' simultaneously rotate clockwise, connecting the mounting shaft sleeve 301 to rotate counterclockwise, and the double split connecting part 301b of the mounting shaft sleeve 301 connects the limiting plate F1 to rotate counterclockwise. After the opening action is completed, the unlocking limiting connecting part F102 of the limiting plate F1 is limited by the unlocking limiting shaft F2. At this time, both the normal side power supply and the spare side power supply are in the double split position of the non-closing state, and the normal side closing is ready as shown in FIG. 6. Figure 15 as shown

[0060] In this double split position, the rotating lever C' is out of contact with the lower lever 502', and the rotating lever C is also out of contact with the lower lever 502; the swing lever 5 is in the maximum anticlockwise rotating position, the blocking protrusion 501a on the upper connecting rod 501 does not block the shifting hole 405' on the shifting lever 4', the swing lever 5' is in the maximum clockwise rotating position, and the blocking protrusion 501a' on the upper connecting rod 501' does not block the shifting hole 405' on the shifting lever 4' as shown in Fig. 4. Figure 16

[0061] The double split state is converted to the standby side power closing state from the normally used side closing preparation state: the handle 6' is inserted into the shifting hole 405' of the shifting lever 4', and is pulled clockwise; the sliding plate 2 is connected to the swing lever 5 and the swing lever 5' to rotate clockwise; after the swing lever A and the swing lever A' are rotated into position, the rotating lever C and the rotating lever C' rotate anticlockwise at the same time, and the connecting shaft sleeve 301 rotates clockwise to realize the standby side power closing.

[0062] The double split state is converted to the normally used side power closing state from the normally used side closing preparation state: the handle 6 is inserted into the shifting hole 405 of the shifting lever 4, and is pulled anticlockwise; the inclined surface of the unlocking limiting shaft connecting hole 402, 402' of the shifting lever 4 is in contact with the unlocking limiting shaft F2, and the unlocking limiting shaft F2 moves downward under the action of the inclined surface; after the unlocking limiting shaft F2 moves downward into position, it releases the limiting of the unlocking limiting connecting part F102 of the limiting plate F1, the connecting shaft sleeve 301 rotates anticlockwise with the limiting plate F1 to realize the normally used side power closing as shown in Fig. 5. Figure 17

[0063] After closing, the handle is released, the shifting lever 4 rotates clockwise under the action of the shifting lever return spring 4a', and the inclined surface releases the pressing of the unlocking limiting shaft F2; the unlocking limiting shaft F2 moves upward into position under the action of the return device as shown in Fig. 6. Figure 18

[0064] The double split state is converted to the normally used side power closing state from the normally used side closing preparation state: the handle 6 is inserted into the shifting hole 405 of the shifting lever 4, and is pulled anticlockwise; the inclined surface of the unlocking limiting shaft connecting hole 402, 402' of the shifting lever 4 is in contact with the unlocking limiting shaft F2, and the unlocking limiting shaft F2 moves downward under the action of the inclined surface; after the unlocking limiting shaft F2 moves downward into position, it releases the limiting of the unlocking limiting connecting part F102 of the limiting plate F1, the connecting shaft sleeve 301 rotates anticlockwise with the limiting plate F1 to realize the normally used side power closing as shown in Fig. 5. Figure 18 19 The double split state is converted to the normally used side power closing state from the normally used side closing preparation state: the handle 6 is inserted into the shifting hole 405 of the shifting lever 4, and is pulled anticlockwise; the inclined surface of the unlocking limiting shaft connecting hole 402, 402' of the shifting lever 4 is in contact with the unlocking limiting shaft F2, and the unlocking limiting shaft F2 moves downward under the action of the inclined surface; after the unlocking limiting shaft F2 moves downward into position, it releases the limiting of the unlocking limiting connecting part F102 of the limiting plate F1, the connecting shaft sleeve 301 rotates anticlockwise with the limiting plate F1 to realize the normally used side power closing as shown in Fig. 5.​​​​

[0065] Insert the handle 6 into the actuating hole 405 of the actuating lever 4 on the normal side, and pull it clockwise. At this time, the left side wall of the sliding plate linkage hole 403' of the actuating lever 4 links the sliding plate actuating shaft 2b of the sliding plate 2 and moves the sliding plate 2 to the right. While moving to the right, the sliding plate 2 links the sliding plate linkage hole 403' of the standby side actuating lever 4' through the sliding plate actuating shaft 2b, and overcomes the spring force of the actuating lever return spring 4a to make the standby side actuating lever 4' rotate counterclockwise around the actuating lever mounting shaft 110.

[0066] After the handle 6 links the actuating lever 4 on the normal side to actuate to the position, the operating mechanism performs the opening operation. During the opening operation, the rotating lever C and the rotating lever C' simultaneously rotate counterclockwise, the mounting shaft sleeve 301 rotates clockwise, and the double split linkage part 301b of the mounting shaft sleeve 301 links the limiting plate F1 to rotate clockwise. After the opening operation is completed, the unlocking limiting linkage part F102 of the limiting plate F1 is limited by the unlocking shaft F2. At this time, both the normal side power supply and the standby side power supply are in the double split position, and the standby side is ready for closing, as shown in the accompanying drawings. Figure 20

[0067] At this double split position, the rotating lever C' is not in contact with the lower lever 502', and the rotating lever C is not in contact with the lower lever 502. The swing lever 5 is at the maximum counterclockwise rotation position, and the blocking protrusion 501 on the upper connecting rod 501 does not block the actuating hole 405' on the actuating lever 4'. The swing lever 5' is at the maximum clockwise rotation position, and the blocking protrusion 501' on the upper connecting rod 501' does not block the actuating hole 405' on the actuating lever 4', as shown in the accompanying drawings. Figure 16

[0068] The standby side is ready for closing in the double split state, and the normal side power supply is converted to the closing state. Insert the handle 6 into the actuating hole 405 of the actuating lever 4 on the normal side, and pull it counterclockwise. Through the sliding plate 2, the swing lever A1 and the swing lever A1' are linked to rotate counterclockwise. After the swing lever A1 and the swing lever A1' are rotated to the position, the rotating lever C and the rotating lever C' simultaneously rotate clockwise, the mounting shaft sleeve 301 rotates counterclockwise, and the normal side power supply is closed.

[0069] ​​The double-break state standby side closing preparation is ready to switch to the standby side power supply closing state: insert the handle 6' into the dial hole 405' of the dial lever 4' on the standby side, and pull clockwise; the inclined surface of the unlocking limiting shaft linkage hole 402' of the dial lever 4' is in contact with the unlocking limiting shaft F2, and the unlocking limiting shaft F2 moves downward under the action of the inclined surface; after the unlocking limiting shaft F2 moves downward to the position, it releases the limiting of the unlocking limiting linkage F102 of the limiting plate F1, the mounting shaft sleeve 301 rotates the limiting plate F1 clockwise, realizes the standby side power supply closing, and the specific process is shown in FIG. 8.
