Description

Technical Field

[0001] This invention relates to the field of electrical component technology, and more specifically to a handle position correction device and a circuit breaker having the same. Background Technology

[0002] A circuit breaker is an overcurrent protection device used for circuit protection and isolation. When a specified electrical anomaly occurs in the system, a circuit breaker provides electrical system protection. A circuit breaker typically has conductive stationary and moving contacts. The moving contact is connected to a contact carrier. The circuit breaker handle cooperates with the contact carrier, allowing the user to operate the handle switch to move the contact carrier between the open and closed positions, thereby moving the moving contact to close or open the circuit.

[0003] However, if the handle switch is not rotating smoothly, it may not be able to reach the preset position. For example, after the moving contact of the circuit breaker disconnects the circuit, the handle switch may not be able to return to the disconnected position due to difficulty in rotation. In this case, it is impossible to determine from the outside of the circuit breaker whether the internal circuit of the circuit breaker is in a disconnected state in a timely manner. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the prior art circuit breaker that cannot return to the disconnected position in time after the circuit is disconnected due to the inflexible rotation of the handle switch, thereby providing a handle position correction device and a circuit breaker having the same.

[0005] To address the aforementioned technical problems, the present invention provides a handle position correction device, comprising: a housing; a handle mounted on a rotating shaft, the rotating shaft being rotatably mounted on the housing; a first rotating plate connected to the handle, the first rotating plate rotating synchronously with the handle; a circuit board fixedly disposed within the housing, one side of the circuit board having a first sliding variable resistor cooperating with the first rotating plate, the first sliding variable resistor being electrically connected to a controller; and a drive mechanism electrically connected to the controller, the drive end of the drive mechanism cooperating with the rotating shaft of the handle for driving the handle to rotate to a preset position.

[0006] Preferably, a follower is installed at the end of the handle's rotating shaft, and the driving end of the drive mechanism cooperates with the follower to drive the handle's rotating shaft.

[0007] Preferably, the follower has a protrusion extending radially outward, and the drive end of the drive mechanism has a groove that mates with the protrusion. The protrusion slides in the groove and has an initial position state and an adjusted position state. When the handle is not rotated to the correct position, the drive end of the drive mechanism moves to make the groove mate with the protrusion and enter the adjusted position state. After the handle is rotated to the correct position by the protrusion, the drive end of the drive mechanism moves again to reset the groove. At this time, the groove and the protrusion return to the initial position state.

[0008] Preferably, a gear is fitted on the shaft of the handle, the gear cooperates with the follower, and the drive end of the drive mechanism is connected to the gear.

[0009] Preferably, a position detection device is connected to the drive end of the drive mechanism, and the position detection device is electrically connected to the controller.

[0010] Preferably, a gear is fitted on the shaft of the handle, a second rotating plate is provided on the gear, and one side of the circuit board has a second sliding resistor that cooperates with the second rotating plate. The second sliding resistor is electrically connected to the controller.

[0011] Preferably, a first stabilizing block is provided on the side of the gear for mounting the second rotating plate, and the first stabilizing block is symmetrically arranged with the second rotating plate.

[0012] Preferably, it further includes: a rotating component, which is rotatably sleeved on the handle's shaft and detachably connected to the handle, the rotating component being used to connect or disconnect the circuitry within the housing.

[0013] Preferably, it further includes: a mounting wheel, which is snapped onto the rotating component, and the first rotating plate is mounted on the mounting wheel.

[0014] Preferably, the mounting wheel is provided with at least one snap-fit ​​block, and the rotating part is provided with a corresponding snap-fit ​​groove for the snap-fit ​​block.

[0015] Preferably, a second stabilizing block is provided on the side of the mounting wheel used to mount the first rotating plate, and the second stabilizing block is symmetrically arranged with the first rotating plate.

[0016] Preferably, it further includes: a mounting housing, the circuit board is disposed inside the mounting housing, and the mounting wheels and gears are partially embedded inside the mounting housing.

[0017] Preferably, a limiting block is provided on the outer periphery of the mounting wheel, and a sliding groove is provided on the mounting shell to cooperate with the limiting block. The sliding groove has a limiting recess for embedding the limiting block.

[0018] In addition, a circuit breaker is provided, including: a handle position correction device of any of the above embodiments.

[0019] The technical solution of this invention has the following advantages:

[0020] 1. The handle position correction device provided by this invention includes a first rotating plate on the handle. The sliding of the first rotating plate on a first sliding variable resistor causes a change in the resistance of the circuit. The controller determines the handle position by judging the resistance, thereby determining the state of the circuit breaker. When the state of the circuit breaker is inconsistent with the handle position, the drive mechanism rotates the handle, thus returning the handle to the open position in a timely manner, protecting the safety of personnel maintaining the circuit. Furthermore, the real-time display of the handle position through resistance changes enhances safety.

[0021] 2. The handle position correction device provided by the present invention has a follower installed at the end of the handle's rotating shaft. The driving end of the driving mechanism cooperates with the follower to drive the handle's rotating shaft. When the circuit breaker and the handle are not in the same position, the driving mechanism can remotely rotate the handle to the disconnected position. Remote operation can save maintenance personnel's time.

[0022] 3. The handle position correction device provided by the present invention places the circuit board inside the mounting housing to prevent dust, powder and other objects from falling on the sliding resistor and affecting the change of resistance, thereby improving the accuracy of handle position detection.

[0023] 4. The circuit breaker provided by the present invention has a rotating plate on the handle position correction device. The judgment is made by rotating the plate in the sliding variable resistor area. Compared with the photoelectric switch detection device in the prior art, the accuracy of component assembly can be reduced. When the component is not assembled properly or the component is worn, the component assembly can be corrected by the resistance value.

[0024] 5. The circuit breaker provided by this invention includes a handle position correction device. By adjusting the resistance value caused by the sliding of the rotating plate on the sliding variable resistor, when the resistance value of the handle deviates from the factory-set handle position resistance value after multiple circuit breaker operations, it can be determined that the handle's lifespan has decreased, allowing for timely replacement of the circuit breaker. Furthermore, this application uses resistance value to determine the lifespan of each component, while photoelectric switches can only detect two positions: on and off.

[0025] 6. The circuit breaker provided by the present invention includes a handle position correction device. By rotating the second rotating plate in the area of ​​the second sliding resistor, the position of the cam on the gear is determined. Then, the controller determines whether the drive mechanism needs to rotate forward or backward, and the angle of rotation of the drive mechanism. This greatly improves the control of the circuit breaker state. Since the second sliding resistor can correctly indicate the direction of motor rotation, the resistance value can be used to determine whether the motor should rotate forward or backward and the required rotation angle.

[0026] 7. The circuit breaker provided by the present invention includes a handle position correction device that detects the handle position by trial and error, thereby improving maintenance personnel's judgment of the current state of the circuit and enhancing safety. Attached Figure Description

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The handle position correction device provided in this embodiment is used in the technical field of circuit breakers, etc. The device can determine the handle position and rotate it to the normal position through the drive mechanism when the handle position is abnormal.

[0042] like Figure 1 , 2 As shown in Figures 3 and 5, the handle position correction device provided in this embodiment includes: a housing 1; a handle 2, mounted on a rotating shaft 3, the rotating shaft 3 being rotatably mounted on the housing 1; a first rotating plate 4, connected to the handle 2, the first rotating plate 4 rotating synchronously with the handle 2; a circuit board 5, fixedly disposed inside the housing 1, one side of the circuit board 5 having a first sliding resistor 6 cooperating with the first rotating plate 4, the first sliding resistor 6 being electrically connected to a controller 7; and a drive mechanism 8, electrically connected to the controller 7, the drive end of the drive mechanism 8 cooperating with the rotating shaft 3 of the handle 2, used to drive the handle 2 to rotate to a preset position. By setting the first rotating plate 4 on the handle 2, the sliding of the first rotating plate 4 on the first sliding resistor 6 causes a change in the resistance in the circuit. The controller 7 determines the position of the handle 2 by judging the resistance, thereby determining the state of the circuit breaker. When the state of the circuit breaker is inconsistent with the position of the handle 2, the drive mechanism 8 will rotate the handle 2, thereby causing the handle 2 to return to the disconnected position in time, protecting the safety of personnel maintaining the circuit.

[0043] like Figure 2 ,3 As shown, this embodiment provides a handle position correction device. A follower 9 is installed at the end of the rotating shaft 3 of the handle 2. The driving end of the driving mechanism 8 cooperates with the follower 9 to drive the rotating shaft 3 of the handle 2. The follower 9 and the handle 2 are connected through the rotating shaft 3. In this embodiment, the rotating shaft 3 is a square shaft. Through the cooperation between the driving end and the follower 9, the handle 2 rotates accordingly. The follower 9 makes it easier and more convenient for the driving mechanism 8 to rotate the handle 2. Alternatively, as an alternative embodiment, the follower 9 can also be placed in other positions on the handle 2, such as when the follower 9 is placed close to the handle 2.

[0044] like Figure 3 , 7 As shown, this is the handle position correction device provided in this embodiment. The driving end of the driving mechanism 8 has a protrusion 10 extending radially outward, and the follower 9 has a groove 11 that cooperates with the protrusion 10. The protrusion 10 slides in the groove 11 and has an initial position state and an adjusted position state. When the handle 2 is not rotated to the correct position, the driving end of the driving mechanism 8 moves to make the groove 11 cooperate with the protrusion 10 to enter the adjusted position state. After the handle 2 is rotated to the correct position by the protrusion 10, the driving end of the driving mechanism 8 moves again to reset the groove 11. At this time, the groove 11 and the protrusion 10 return to the initial position state. The rotation of the protrusion 10 abuts against two surfaces of the groove 11, thereby driving the follower 9 to rotate accordingly. When the protrusion 10 abuts against one surface of the groove 11, the drive mechanism 8 can drive the follower 9 to rotate clockwise; when the protrusion 10 abuts against the other surface of the groove 11, the drive mechanism 8 can drive the follower 9 to rotate counterclockwise. The groove 11 is a semi-circular groove on the follower 9. When the protrusion 10 is in its initial position within the groove 11, the handle 2 can be manually controlled to open and close. At this time, the circuit breaker tripping can proceed normally. When the protrusion 10 rotates into the adjustment position, the follower 9 will drive the handle 2 into the open or closed state. After the position of the handle 2 is corrected, the protrusion 10 needs to be rotated back to its initial position; otherwise, the handle 2 will be unable to rotate due to the restriction of the protrusion 10. Alternatively, as an alternative embodiment, a cylinder may be provided on the driving end of the driving mechanism 8, and an arc-shaped waist-shaped hole may be provided on the follower 9. The cylinder slides in the waist-shaped hole, causing the follower 9 to rotate accordingly.

[0045] like Figure 2 , 3As shown in Figure 4, this embodiment provides a handle position correction device. A gear 12 is fitted onto the rotating shaft 3 of the handle 2. The gear 12 cooperates with the follower 9, and the driving end of the drive mechanism 8 is connected to the gear 12. A circular hole is provided in the center of the gear 12. In this embodiment, the drive mechanism 8 can be a motor, and the drive mechanism 8 and the gear 12 cooperate to rotate through a multi-stage reduction device. A protrusion 10 is provided on the side of the gear 12 near the follower 9. Alternatively, as an alternative embodiment, other similar structures can be fitted onto the rotating shaft 3 of the handle 2, which only need to realize the rotation function of the handle 2. For example, a rotating wheel can be fitted onto the handle 2, and the drive mechanism 8 and the rotating wheel are driven by a belt.

[0046] like Figure 2 , 3 As shown, this embodiment provides a handle position correction device. A position detection device is connected to the drive end of the drive mechanism 8, and the position detection device is electrically connected to the controller 7. The position detection device on the drive end is used to locate the position of the protrusion 10 on the gear 12. Only when the protrusion 10 is in the initial position can the handle 2 rotate freely to switch the circuit breaker state. When the protrusion 10 is in other positions, the rotation of the handle 2 will cause the handle 2 to fail to return to its normal state smoothly due to the conflict between the groove 11 and the protrusion 10. At this time, the controller 7 needs to determine the position of the protrusion 10 through the position detection device. When the position of the protrusion 10 is abnormal, the controller 7 sends a signal to the drive mechanism 8, causing the drive mechanism 8 to drive the gear 12 to rotate to the initial position. Alternatively, as an alternative embodiment, the position detection device can be set on the protrusion 10, and by detecting the position of the protrusion 10 in the groove 11, it can be determined whether the drive mechanism 8 needs to rotate.

[0047] like Figure 3 As shown, this embodiment provides a handle position correction device. A gear 12 is sleeved on the rotating shaft 3 of the handle 2, and a second rotating plate 13 is provided on the gear 12. One side of the circuit board 5 has a second sliding resistor 14 that cooperates with the second rotating plate 13. The second sliding resistor 14 is electrically connected to the controller 7. The position detection device in the above solution includes: the second rotating plate 13 and the second sliding resistor 14 on the circuit board 5. By rotating the second rotating plate 13 on the second sliding resistor 14, the position of the bump 10 is determined by the change in resistance. Alternatively, as an alternative embodiment, the second rotating plate 13 can be fixedly mounted on the circuit board 5.

[0048] like Figure 7As shown, this embodiment provides a handle position correction device. A first stabilizing block 19 is provided on the side of the gear 12 where the second rotating plate 13 is mounted. The first stabilizing block 19 and the second rotating plate 13 are symmetrically arranged. In this embodiment, the gear 12 and the gear of the reducer use spur gears. To maintain parallel centerlines, it is necessary to overcome the elastic force of the second rotating plate 13 on the circuit board 5. Therefore, the first stabilizing block 19 is provided at a symmetrical position to the second rotating plate 13 to ensure the engagement between the gears. Alternatively, as an alternative embodiment, a small bearing can be provided on the mounting housing 20, and the gear 12 can be mounted on the small bearing for rotation.

[0049] like Figure 1 , 2 As shown in Figure 6, the handle position correction device provided in this embodiment further includes a rotating component 15. The rotating component 15 is sleeved on the rotating shaft 3 of the handle 2 and is detachably connected to the handle 2. The rotating component 15 is used to drive the circuit inside the housing 1 to connect or disconnect. The rotating component 15 rotates in cooperation with the handle 2, and the electrical equipment is mainly connected and disconnected through the rotating component 15, which can prevent accidental circuit closure caused by others touching it. In addition, as an alternative embodiment, the rotating component 15 can be designed as an integral part of the handle 2.

[0050] like Figure 3 As shown, the handle position correction device provided in this embodiment further includes: a mounting wheel 16, which is snapped onto the rotating member 15, and a first rotating plate 4 mounted on the mounting wheel 16. The mounting wheel 16 and the rotating member 15 are fixed together by snapping; the first rotating plate 4 is mounted on the side near the circuit board 5 and abuts against the first sliding resistor 6. Alternatively, as an alternative embodiment, the mounting wheel 16 and the rotating member 15 can be fixedly connected by bolts or other means.

[0051] like Figure 3 , 6 As shown, this embodiment provides a handle position correction device. The mounting wheel 16 has at least one locking block 17, and the rotating member 15 has a corresponding locking groove 18 on the locking block 17. A first rotating piece 4 is mounted on the mounting wheel 16, which has at least one locking block 17 that engages with the locking groove 18 on the rotating member 15, allowing the mounting wheel 16 and the rotating member 15 to rotate together. In this embodiment, the mounting wheel 16 has three locking blocks 17, and correspondingly, the rotating member 15 has three locking grooves 18. Alternatively, as an alternative embodiment, the first rotating piece 4 can also be directly mounted on the rotating member 15.

[0052] like Figure 6As shown, this embodiment provides a handle position correction device. A second stabilizing block 23 is provided on the side of the mounting wheel 16 where the first rotating plate 4 is mounted. The second stabilizing block 23 is symmetrically arranged with the first rotating plate 4. In this embodiment, the second stabilizing block 23 is semi-circular. Since the first rotating plate 4 needs to apply a certain force to abut against the sliding resistor to ensure sufficient contact, and because the first rotating plate 4 is made of a certain metal material, it has a certain rebound force, thus providing a certain reaction force to the mounting wheel 16. The second stabilizing block 23 prevents the mounting wheel 16 from tilting, ensuring smooth rotation. Alternatively, as an alternative embodiment, support columns can be provided on the gear 12 and the mounting wheel 16, and a sliding groove 21 can be provided on the circuit board 5, allowing the support columns to slide within the sliding groove 21.

[0053] like Figure 2 , 3 As shown, the handle position correction device provided in this embodiment further includes: a mounting housing 20, the circuit board 5 disposed within the mounting housing 20, and portions of the mounting wheel 16 and the gear 12 embedded within the mounting housing 20. The mounting housing 20 contains a first rotating plate 4, a second rotating plate 13, and the circuit board 5, used to prevent dust and other substances from entering the sliding resistor area and affecting resistance changes. Alternatively, as an alternative embodiment, the mounting housing 20 can be fitted with other components, such as embedding the gear 12 within the mounting housing 20.

[0054] like Figure 3 , 6 As shown, this embodiment provides a handle position correction device. A limiting block 22 is provided on the outer periphery of the mounting wheel 16. The mounting shell 20 has a sliding groove 21 that cooperates with the limiting block 22. The sliding groove 21 has a limiting recess for embedding the limiting block 22. The limiting block 22 on the mounting wheel 16 slides within the sliding groove 21. Since the mounting wheel 16 and the rotating member 15 are fixed by a snap-fit ​​connection, the mounting wheel 16 rotates synchronously with the rotating member 15. The limiting block 22 on the mounting wheel 16 limits the rotation of the rotating member 15. The rotating member 15 has a torsion spring inside, causing it to rotate in the closing direction of the handle 2. When the limiting block 22 slides into the limiting recess, the rotating member 15 is in the disengaged position. Alternatively, as an alternative embodiment, the sliding groove 21 may not have a limiting recess; instead, the inner walls at both ends of the sliding groove 21 may limit the movement of the limiting block 22.

[0055] Installation method of the handle position correction device: The handle 2 is located at one end of the rotating shaft 3. The rotating part 15 is sleeved on the rotating shaft 3 and rotates in cooperation with the handle 2. The rotating part 15 is inserted into the snap-fit ​​groove 18 through the snap-fit ​​block 17, so that the mounting wheel 16 is fixed to the rotating part 15. The first rotating piece 4 is fixed on the mounting wheel 16 by the snap-fit. At the same time, the first rotating piece 4 abuts against the first sliding variable resistor 6 on one side of the circuit board 5. On the other side of the circuit board 5, the second rotating piece 13 on the gear 12 abuts against the second sliding variable resistor 14. The rotating shaft 3 passes through the rotating part 15, the gear 12, the circuit board 5, and the mounting wheel 16. A follower 9 is provided at the end of the rotating shaft 3.

[0056] In addition, such as Figure 1 As shown, the circuit breaker provided in this embodiment has a handle position correction device as described in any of the above-described schemes installed inside the mounting housing 20. By installing the handle position correction device in the circuit breaker, the position of the handle 2 can be detected in real time by the sliding of the first rotating plate 4 and the sliding of the first sliding variable resistor 6, and the follower 9 can be rotated by the rotation of the drive mechanism 8, thereby enabling remote operation of the handle 2 to disconnect and connect.

[0057] The working principle of the handle position correction device in the circuit breaker: The handle position correction device described above is installed in the circuit breaker. When handle 2 is in the open position, the circuit breaker is in the open state. Closing handle 2 at this time connects the circuit breaker to the circuit. When the circuit is abnormal, the tripping mechanism in the circuit breaker disconnects the circuit. Under normal circumstances, handle 2 needs to return to the open position under the action of the torsion spring. However, when handle 2 has difficulty rotating, it remains in the closed position. When handle 2 is in the closed position, the first rotating plate 4 contacts the first sliding resistor 6. The controller 7 determines that the handle 2 position is abnormal and sends a signal to the drive mechanism 8, causing the drive mechanism 8 to rotate accordingly. The drive mechanism 8 drives the gear 12 to rotate. The protrusion 10 on the gear 12 abuts against one side of the groove 11 on the follower 9 and rotates, causing the handle 2 to rotate accordingly. When the gear 12 rotates, the controller 7 mainly determines the position of the protrusion 10 by the position of the second rotating plate 13 on the second sliding resistor 14, and thus determines the rotation position of the handle 2 driven by the drive mechanism 8. After the drive mechanism 8 rotates the handle 2, the controller 7 needs to return the protrusion 10 to its initial position. Only in the initial position can the handle 2 be manually opened and closed or automatically tripped. When both the circuit breaker and the handle 2 are in normal condition, commands can be sent to the controller 7 remotely to cause the drive mechanism 8 to close and open the circuit breaker.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
