[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-3 As shown in the figure, this utility model embodiment provides a manual operation auxiliary device for a high-voltage switch and a high-voltage switch. The manual operation auxiliary device for a high-voltage switch is applied to the high-voltage switch to assist in the opening and closing of the high-voltage switch. High-voltage switches include circuit breakers, disconnecting switches, maintenance grounding switches, and fast grounding switches, etc.

[0039] The high-voltage switch provided in this embodiment includes a closing and opening operating mechanism and a manual operation assist device for the high-voltage switch provided in this embodiment. The manual operation assist device for the high-voltage switch can assist the closing and opening operating mechanism in its operation.

[0040] The manual operation auxiliary device of the high-voltage switch includes a housing 1 and a drive mechanism 2. The drive mechanism 2 includes a drive component 21, a transmission assembly, and a transfer transmission rod 22. The drive component 21 and the transmission assembly are both housed in the housing 1. The first end of the transfer transmission rod 22 is connected to the drive end of the drive component 21 through the transmission assembly. The opening and closing operation mechanism is provided with an operation hole. The second end of the transfer transmission rod 22 is connected to the operation hole of the opening and closing operation mechanism. The drive component 21 drives the transfer transmission rod 22 to rotate through the transmission assembly, so that the transfer transmission rod 22 drives the opening and closing operation mechanism to operate, thereby realizing the opening and closing of the high-voltage switch.

[0041] In the manual operation assist device of this high-voltage switch, the drive component 21 drives the transfer transmission rod 22 to rotate through the transmission assembly, so that the transfer transmission rod 22 drives the high-voltage switch to open and close, eliminating the need for manual rotation of the handle, saving time and effort, and improving work efficiency.

[0042] Optionally, the transmission assembly includes an input gear 23 and an output gear 24. The input gear 23 is located at the driving end of the driving member 21, and the output gear 24 is located at the first end of the adapter transmission rod 22. The driving member 21 can drive the input gear 23 to rotate and can drive the output gear 24 to rotate simultaneously. The output gear 24 drives the adapter transmission rod 22 to rotate. The number of teeth of the input gear 23 is less than the number of teeth of the output gear 24. In this structure, by setting the input gear 23 and the output gear 24, and the number of teeth of the input gear 23 is less than the number of teeth of the output gear 24, the adapter transmission rod 22 can be decelerated and torque increased. The structural design is reasonable.

[0043] Furthermore, the transmission assembly also includes at least one double-row gear 25, which includes a first gear 251 and a second gear 252 with their axes coincident, wherein the number of teeth of the first gear 251 is greater than the number of teeth of the second gear 252.

[0044] When there is only one double-row gear 25, the first gear 251 of the double-row gear 25 meshes with the input gear 23, and the second gear 252 of the double-row gear 25 meshes with the output gear 24. When there are multiple double-row gears 25, they are distributed sequentially along the direction from the input gear 23 to the output gear 24. In any two adjacent double-row gears 25, the second gear 252 of the double-row gear 25 closer to the input gear 23 meshes with the first gear 251 of the double-row gear 25 farther from the input gear 23, and the first gear 251 of the double-row gear 25 adjacent to the input gear 23 meshes with the input gear 23, and the second gear 252 of the double-row gear 25 adjacent to the output gear 24 meshes with the output gear 24. By setting at least one double-row gear 25 between the input gear 23 and the output gear 24, the effect of speed reduction and torque increase is further enhanced.

[0045] Optionally, such as Figure 2As shown, a first support plate 11 and a second support plate 12, parallel to each other and spaced apart, are disposed inside the housing 1. Both the first support plate 11 and the second support plate 12 are welded to the bottom plate of the housing 1. A driving component 21 is fixedly connected to the first support plate 11. The driving end of the driving component 21 extends through the first support plate 11 to the space between the first support plate 11 and the second support plate 12. An input gear 23, a double-row gear 25, and an output gear 24 are all disposed between the first support plate 11 and the second support plate 12. The input gear 23 is connected to the driving end of the driving component 21. The double-row gear 25 is rotatably connected to the first support plate 11 and / or the second support plate 12. The output gear 24 is rotatably connected to the first support plate 11 and / or the second support plate 12. This structure enables the installation of the driving component 21, the double-row gear 25, and the output gear 24.

[0046] Optionally, such as Figures 2-3 As shown, the double-row gear 25 also includes a connecting shaft 253 connecting the first gear 251 and the second gear 252. The two ends of the connecting shaft 253 protrude from the first gear 251 and the second gear 252 respectively. The two ends of the connecting shaft 253 are rotatably connected to the first support plate 11 and the second support plate 12 inside the housing 1 respectively. The connecting shaft 253 is rotatably connected between the first support plate 11 and the second support plate 12 respectively, making the installation of the double-row gear 25 more stable.

[0047] Optionally, the output gear 24 is provided with a central shaft 241 connected to the output gear 24. The central shaft 241 is rotatably connected to the second support plate 12, and at the same time, the central shaft 241 passes through the second support plate 12 and is connected to the first end of the adapter transmission rod 22. This structure realizes the installation of the output gear 24 and the connection between the output gear 24 and the adapter transmission rod 22.

[0048] Optionally, the manual operation assistance device of the high-voltage switch also includes an operation display screen 4, which is mounted on the housing 1. The operation display screen 4 can be connected to the control module 5 inside the manual operation assistance device of the high-voltage switch to realize human-machine interaction. It can convert the operator's instructions into control functions, control the start and stop of the drive component 21, or display alarms and diagnose faults.

[0049] To identify whether the closing / opening mechanism is fully closed or open, the housing 1 is equipped with a closing / opening signal interface 7. This interface 7 is connected via wires to the control module 5 and the connector of the closing / opening mechanism. When the closing mechanism is fully closed, the connector transmits a closing signal to the control module 5 through the closing / opening signal interface 7. The control module 5 recognizes that the closing mechanism is fully closed and stops the manual operation assist device of the high-voltage switch. Similarly, when the opening mechanism is fully open, the connector transmits an opening signal to the control module 5 through the closing / opening signal interface 7. The control module 5 recognizes that the opening mechanism is fully open and stops the manual operation assist device of the high-voltage switch. This structure automatically identifies whether the closing / opening mechanism is fully open, eliminating the need for manual visual inspection.

[0050] Optionally, the manual operation assist device of the high-voltage switch also includes a torque sensor 3. The torque sensor 3 is disposed inside the housing 1 and connected to the base plate inside the housing 1 via a bracket. The central shaft 241 passes through the output gear 24, and the end of the central shaft 241 away from the adapter transmission rod 22 is connected to the input shaft of the torque sensor 3. The torque sensor 3 monitors torque changes in real time and feeds the torque back to the control module 5. When the torque exceeds the torque threshold, the manual operation assist device of the high-voltage switch generates an abnormal alarm and feeds the abnormal alarm signal back to the operation display screen 4, allowing the operator to promptly identify the status of the manual operation assist device of the high-voltage switch.

[0051] Optionally, the driving component 21 can be a motor, with a drive shaft at the drive end of the motor, and the input gear 23 connected to the drive shaft of the motor so that the motor drives the input gear 23 to rotate.

[0052] In this embodiment, a power interface 6 is also provided on the housing 1 to facilitate power connection.

[0053] The operation procedure of the manual operation auxiliary device of the high-voltage switch is as follows: turn on the power - set the torque threshold - set the clockwise / counterclockwise mode of the motor - press the start button - the motor starts running - the opening / closing operation mechanism reaches the opening / closing position - press the stop button - the manual operation auxiliary device of the high-voltage switch stops - turn off the power. In the above process, when the start button is pressed, the torque sensor 3 will monitor the torque data in real time. When the torque is normal, the manual operation auxiliary device of the high-voltage switch will execute according to the above procedure. When the torque is abnormal, the manual operation auxiliary device of the high-voltage switch will be directly controlled to stop.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
