Description

Technical Field

[0001] The present disclosure relates to a remote operation module and a circuit breaker having the remote operation module. Background Art

[0002] The remote operation module can be used to remotely control the closing and opening of a circuit breaker. The remote operation module can have a handle, an actuator such as a motor, and a transmission mechanism that transmits the power of the actuator to the handle. The handle can be connected to the handle of the circuit breaker to control the closing and opening of the circuit breaker. Known remote operation modules use gears to drive the toothed handle of the remote operation module. However, after the handle is driven to the closing position, if the actuator does not stop driving in time, tooth breakage or motor burnout may occur, resulting in low reliability. To improve reliability, such a remote operation module needs to be provided with a high-precision position detection device, which increases the cost of the product. In addition, due to relying on high-precision position detection, when using a Hall sensor to detect the position, its operation will be affected by temperature, and the remote operation module can only work reliably within a temperature range of -20°C to 60°C at most.

[0003] In addition, in such a structure in which a gear is used to drive the toothed handle of the remote operation module, after the handle of the remote operation module moves to the closing position, the actuator must also be reversed so as not to affect the free rotation of the handle to meet the requirement of direct manual operation in an emergency. This requirement for reversal also further increases the cost. Summary of the Utility Model

[0013] In one configuration, one end of the connecting rod makes a circular motion around a center of a circle under the drive of the actuator. The other end of the connecting rod has a chute. The handle has a protrusion as the first force receiving portion. The protrusion is placed in the chute and can move to the end of the chute as the first force application portion.

[0032] The present application will be described below with reference to the accompanying drawings, in which several embodiments of the present application are shown. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and fully explain the protection scope of the present application to those skilled in the art.

[0033] It should be understood that in all the drawings, the same reference numerals represent the same elements. In the drawings, for clarity, the dimensions of some features may be deformed.

[0034] It should be understood that the terms in the specification are only used to describe specific embodiments and are not intended to limit the present application. All terms used in the specification (including technical terms and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0035] Hereinafter, with reference to the accompanying drawings, a remote operation module and a circuit breaker having the remote operation module according to some embodiments of the present application will be described. Figure 1 A circuit breaker according to the present disclosure is shown. The circuit breaker may include a remote operation module 1 and a circuit breaker body 2. The remote operation module may be used to control the closing and opening of the circuit breaker, thereby controlling the connection and disconnection of the circuit. The remote operation module 1 includes a handle 5. The circuit breaker body 2 includes a circuit breaker handle 50. The handle 5 may be linked with the circuit breaker handle 50 to control the closing and opening of the circuit breaker.

[0036] Figure 2A and Figure 2B Schematic diagrams of the internal structure of a remote operation module according to an exemplary configuration of the present disclosure are shown from the front and the back. As shown, the remote operation module 1 includes a housing 10 and an actuator 3, a handle 5, and a transmission mechanism located within the housing 10 for transmitting driving force between the actuator 3 and the handle 5. The actuator 3 may be any device capable of providing driving force, such as an electric motor, etc. The transmission mechanism may include a link or a cam (which will be described in detail hereinafter). The transmission mechanism may also include an intermediate transmission component for transmitting the driving force of the actuator to the link or the cam, such as a worm 31 coupled to the output shaft of the actuator 3 and one or more intermediate transmission gears cooperating with the worm 31, etc. Of course, the intermediate transmission component or some of the components in the intermediate transmission component may also be omitted.

[0037] The link or the cam is configured to be movable under the drive of the actuator 3. The link or the cam has a first force application portion. The handle 5 has a first force receiving portion capable of interacting with the first force application portion. The transmission mechanism may be configured such that when the actuator is driven in the same direction (the first direction or the forward direction), the first force application portion can move in a direction approaching the first force receiving portion. Once the first force application portion acts on the first force receiving portion to cause the handle to move to the position of closing the circuit (i.e., the closing position of the circuit breaker), the first force application portion moves in a direction away from the first force receiving portion.

[0038] Due to the above structure of the transmission mechanism, after the handle moves to the closing position, the first force application part of the transmission mechanism can automatically move away from the first force receiving part of the handle. Therefore, even if the actuator continues to drive in the same direction, the first force application part will not continue to interact with the first force receiving part, causing structural damage or burning out of the actuator. Therefore, it is not necessary to accurately detect the position of the transmission mechanism. Therefore, the remote operation module according to the present disclosure has high reliability and low cost.

[0039] Some exemplary embodiments of the remote operation module according to the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that in the following embodiments, the same reference numerals represent the same or similar components, and the description of the same or similar components described above and in other embodiments will be omitted. Without departing from the present disclosure, the foregoing features and the features in each embodiment can be combined with each other to form new embodiments.

[0040] First Embodiment

[0041] Figures 3 to 11B The internal structure diagram of the remote operation module according to the first embodiment of the present disclosure is schematically shown. In this embodiment, the transmission mechanism includes a connecting rod. The connecting rod is driven by an actuator 3. The connecting rod includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 can move in a circular motion around a center O1. The other end of the first connecting rod 41 is connected to the second connecting rod 42 in a pivotable manner relative to the second connecting rod 42. The second connecting rod 42 can pivot around a pivot axis O2. A first force application part 421 is provided on the second connecting rod 42. The handle 5 of the remote operation module has a first force receiving part 51. The first force application part 421 can interact with the first force receiving part 51 to move the handle 5 to the closing position (i.e., the position where the circuit is connected).

[0042] In one structure, the transmission mechanism further includes a driving wheel 7 that receives the driving force of the actuator 3. The one end of the first connecting rod is connected to the disk of the driving wheel 7 through a pin shaft 71, so as to move in a circular motion around the center O1 of the driving wheel 7.

[0043] As Figures 3 to 6 shown in the closing process shown, when the actuator 3 drives in the same direction, for example, when the actuator 3 drives the driving wheel 7 to rotate in the first direction ( Figures 3 to 6 the clockwise direction in Figure 3 and Figure 4As shown, the first link 41 drives the second link 42 to pivot in the clockwise direction, so that the first force application part 421 of the second link 42 moves towards the direction close to the first force receiving part 51. The first force application part 421 interacts with the first force receiving part 51 at the position shown in Figure 4 and moves the handle 5 to the closing position. Then, as the driving wheel 7 continues to rotate in the first direction and drives the first link 41 to move to the position shown in Figure 5 , the first link 41 drives the second link 42 to pivot in the reverse direction (i.e., counterclockwise), so that the first force application part 421 of the second link 42 moves away from the direction of the first force receiving part 51 until it stops at the position shown in Figure 6 after moving a predetermined stroke, thus completing the remote closing process.

[0044] With the above structure, after the handle 5 is remotely closed, the second link 42 automatically moves in the reverse direction, causing the first force application part 421 to move away from the first force receiving part 51. Therefore, during the closing process, even if the actuator continues to drive in the original direction, component damage or actuator burnout will not occur. Therefore, the remote operation module according to the first embodiment of the present disclosure has high reliability and does not require a precise position detection device to control the precise stop position of the link, thereby reducing costs. In addition, since the second link 42 automatically moves in the reverse direction to make way for the handle, the actuator does not need to be driven in the reverse direction after closing and will not interfere with the manual closing and opening of the handle 5.

[0045] In this embodiment, the remote operation module may further include a trip bar 6. The trip bar 6 is configured to actuate to disconnect the circuit when a force is applied. In one configuration, the trip bar 6 can rotate around a pivot axis, and one end thereof extends out of the remote operation module through an opening 62 (see Figure 7A and Figure 7B ) and is linked with the tripping device in the circuit breaker body 2. When the trip bar 6 pivots under the action of a force, the end extending out of the remote operation module can interact with the tripping device in the circuit breaker body 2, so that the circuit breaker trips and the circuit is disconnected. In this embodiment, a second force receiving part 61 is provided on the trip bar 6, and a second force application part 422 capable of interacting with the second force receiving part 61 is provided on the second link 42.

[0046] Figure 7A and Figure 7B respectively show schematic diagrams of the remote opening of the remote operation module according to the first embodiment of the present disclosure from the front and back. The following describes in the order of Figure 6 , Figure 7A and Figure 7B , and Figure 3 When the actuator moves in the first direction (for example, making Figure 7AThe remote opening process of the remote operation module according to the first embodiment of the present disclosure when driving in the direction of the driving wheel 7 rotating clockwise in (). After the remote operation module is in the Figure 6 shown position, when remote opening is required, the actuator 3 can continue to be driven in the first direction. At this time, the first link 41 will follow the driving wheel 7 from Figure 6 the shown position to Figure 7A the shown position. Correspondingly, the second link 42 is driven by the first link 41 from Figure 6 the shown position to pivot to Figure 7A the shown position. At Figure 7A the shown position, as shown in Figure 7B showing the back structure at this position, the second force application portion 422 on the second link 42 will interact with the second force receiving portion 61 on the trip bar 6, thereby driving the trip bar 6 to pivot and tripping the circuit breaker, and further realizing remote opening and circuit disconnection. After tripping is completed, the actuator 3 can continue to be driven in the first direction, so that the first link 41 follows the driving wheel 7 from Figure 7A the shown position to move back to Figure 3 the position shown in Figure 7A During this period, the second link 42 will be driven by the first link 41 to pivot reversely from Figure 3 the position shown in

[0047] Through the above structure, remote opening can be further realized with a simple structure without additionally adding other components. And by adopting the above structure, the second link can also automatically move reversely after tripping, so component damage can also be avoided, and there is no need to use a precise position detection device to detect the position of the link.

[0048] In this embodiment, the transmission mechanism is configured such that during the process of the actuator 3 driving the driving wheel 7 to rotate one week in the first direction, the interaction between the first force application portion 421 and the first force receiving portion 51 and the interaction between the second force application portion 422 and the second force receiving portion 61 can occur. That is to say, when the actuator 3 drives the driving wheel 7 to rotate only in one direction, the process of remote closing and remote opening can be realized by driving the second link through the first link. In this way, a unidirectional drive actuator (such as a unidirectional rotating motor) can be used to realize remote closing and remote opening, thus further reducing the cost.

[0049] In this embodiment, optionally, the remote operation module may further include at least one position sensor. The position sensor is used to detect the position of the transmission mechanism. The remote operation module can control the actuator 3 according to the result of the position detection, so that the transmission mechanism stops at a predetermined stroke after remote closing and / or remote opening.

[0050] In this embodiment, as Figures 3 to 7B shown, the position sensor may include a first microswitch 82 and / or a second microswitch 81. The first microswitch 82 and the second microswitch 81 may be arranged at the positions as Figures 3 to 7B shown. The position of the first microswitch 82 is set such that after the first force application part 421 interacts with the first force receiving part 51, after the first link 41 continues to move a predetermined stroke, that is, when the first link 41 moves to the position as Figure 6 shown, the first link 41 (for example, the first protrusion 412 of the first link 41, see Figure 6 ) contacts the first microswitch 82, thereby triggering the first microswitch to stop the drive of the actuator 3, so that the transmission mechanism stops at the position as Figure 6 shown after remote closing. The position of the second microswitch 81 is set such that after the second force application part 422 interacts with the second force receiving part 61, after the first link 41 continues to move a predetermined stroke, that is, when the first link 41 moves from the position as Figure 7A shown to the position as Figure 3 shown, the first link 41 (for example, the second protrusion 411 of the first link 41, see Figure 3 ) contacts the second microswitch 81, thereby triggering the second microswitch to stop the drive of the actuator 3, so that the transmission mechanism stops at the position as Figure 3 shown after remote opening.

[0051] As mentioned above, since the present disclosure adopts a structure in which the second link can automatically move in the reverse direction, the present disclosure has a lower requirement for the accuracy of position detection. When using the above-mentioned microswitches, the installation positions of the microswitches do not need to meet high-precision requirements, but only need to stop the actuator within a period of time after remote opening and / or remote closing. This also reduces the manufacturing cost of the remote operation module.

[0052] In an alternative configuration, the position sensor may also adopt a Hall sensor or a magnetic reed switch 9 or other similar position sensors. In this configuration, as Figure 24As shown, a magnet 72 is provided on the drive wheel 7. A Hall sensor or a reed switch 9 is provided at a position similar to the position described for the above-mentioned first microswitch 82 and / or second microswitch 81. After the drive wheel 7 continues to move a predetermined stroke after remote closing and / or remote opening, the magnet on the drive wheel moves to a position corresponding to the Hall sensor or the reed switch 9, thereby controlling the actuator 3 to stop driving. Since high-precision position measurement is not required, even if the detection of the Hall sensor or the reed switch is affected by temperature, the reliability of the remote operation module can be ensured. After testing, the remote operation module according to the present disclosure can work reliably at least in the temperature range of -20°C to 80°C.

[0053] In another alternative configuration, a timer can be used instead of the position sensor. In this configuration, the remote operation module determines the driving position of the actuator according to the timing of the timer, and then determines the position of the transmission mechanism, so as to stop driving the actuator 3 when the transmission mechanism reaches a predetermined position.

[0054] The following combines Figure 3 、 Figure 4 、 Figures 8 to 10 、 Figure 11A 、 Figure 11B Describe another implementation manner of the remote operation module according to the first embodiment of the present disclosure. In this implementation manner, the same reference numerals represent the same components, and the description of these components is omitted.

[0055] In this implementation manner, the transmission mechanism is configured such that, when the drive wheel 7 drives the link to move in the first direction (e.g., the clockwise direction in Figure 3 and Figure 10 shown positions) from the initial position, an interaction between the first force application portion 421 and the first force receiving portion 51 occurs (see Figure 3 、 Figure 4 、 Figures 8 to 10 and Figure 11A ), and when the drive wheel 7 drives the link to move in the second direction opposite to the first direction (e.g., the counterclockwise direction in Figure 4 ), an interaction between the second force application portion 422 and the second force receiving portion 61 occurs (see Figure 3 、 Figure 4 、 Figures 8 to 10 and Figure 11A ). Figure 11B ).

[0056] Specifically, referring to Figure 3 、 Figure 4 、 Figures 8 to 10 Describe the remote closing process of the remote operation module of this embodiment. First, the actuator 3 drives the drive wheel 7 fromFigure 3 The initial position shown rotates in the first direction to Figure 4 the position shown. Accordingly, the drive wheel 7 drives the first link 41 from Figure 3 the initial position shown to Figure 4 the position shown, and the first link 41 drives the second link 42 from Figure 3 the initial position shown to pivot clockwise to Figure 4 the position shown. At Figure 4 the position shown, the interaction between the first force application part 421 and the first force receiving part 51 drives the handle 5 to move to achieve remote closing. Then, the actuator 3 continues to drive the drive wheel 7 to rotate a stroke in the first direction to reach Figure 8 the position shown. Accordingly, the second link 42 pivots in the reverse direction (i.e., counterclockwise) away from the first force receiving part 51 to Figure 8 the position shown. Then, the actuator 3 reversely drives the drive wheel 7 to rotate in the second direction opposite to the first direction ( Figures 8 to 10 the counterclockwise direction in Figure 8 the position shown via Figure 9 the position shown and back to Figure 10 the initial position shown.

[0057] Next, refer to Figure 10 , Figure 11A and Figure 11B , and Figure 3 to describe the remote opening process of the remote operation module of this embodiment. When the remote operation module completes remote closing and is in Figure 10 the initial position shown, the actuator 3 reversely drives the drive wheel 7 to rotate in the second direction ( Figure 10 and Figure 11A the counterclockwise direction in Figure 11A the position shown. Accordingly, the drive wheel 7 drives the first link 41 to move to Figure 11A the position shown, and the first link 41 drives the second link 42 to pivot to Figure 11A the position shown. At Figure 11A the position shown, as shown in Figure 11B showing the back structure of the remote operation module at this position, the interaction between the second force application part 422 on the second link 42 and the second force receiving part 61 on the trip bar 6 causes the trip bar 6 to pivot, thereby driving the circuit breaker to trip, thus achieving remote opening and circuit disconnection. After completing remote opening, the actuator 3 drives the drive wheel 7 to rotate in the first direction ( Figure 11A the clockwise direction in Figure 3The initial position shown.

[0058] That is to say, in this embodiment, the actuator 3 can drive the drive wheel 7 to rotate forward and backward. When the drive wheel 7 rotates forward, it drives the second link to complete the remote closing action, and then the drive wheel 7 rotates backward and returns to the initial position; when the drive wheel 7 rotates backward from the initial position, it completes the remote opening action, and then rotates forward and returns to the initial position.

[0059] In this embodiment, various position sensors or timers described above can be used to detect the position of the transmission mechanism, so that the actuator 3 stops driving at the required position. For example, the first microswitch 82 can be set so that the first link 41 contacts the first microswitch 82 at the position shown Figure 11A (i.e., the position where the second force application part 422 interacts with the second force receiving part 61). The second microswitch 81 can be set so that the first link 41 contacts the second microswitch 82 at the initial position shown Figure 3 or Figure 10 shown.

[0060] Second Embodiment

[0061] The following refers to Figures 12 to 15 Describe the remote operation module according to the second embodiment of the present disclosure. In this embodiment, the transmission mechanism includes a cam 4. The cam 4 is configured to rotate around the pivot O3 under the drive of the actuator 3. The cam 4 has a part that can interact with the first force receiving part 51 of the handle 5, and this part serves as the first force application part of the cam 4. The cam 4 is configured such that when the actuator 3 drives the cam 4 to rotate in the same direction (counterclockwise direction in the figure), the first force application part of the cam 4 moves toward the direction close to the first force receiving part 51, and at the position shown Figure 12 acts on the first force receiving part 51. The cam 4 is further configured such that when the actuator 3 continues to drive the cam 4 to rotate in the same direction (counterclockwise direction in the figure), the first force application part of the cam 4 interacts with the first force receiving part 51 of the handle 5 and pushes the handle 5 to the closing position (see Figures 12 to 14 ). The cam 4 is further configured such that once the first force application part causes the handle to move to the closing position (i.e., the position where the circuit is switched on, see Figure 14 ), the first force application part will move away from the first force receiving part 51 (see Figure 15 ).

[0062] With the above-described configuration of the cam 4, after the handle 5 is remotely closed, the first force application part can also automatically move away from the first force receiving part. Therefore, during the closing process, even if the actuator continues to drive, component damage or actuator burnout will not occur. Thus, the remote operation module according to the second embodiment of the present disclosure can also achieve a technical effect similar to that of the first embodiment.

[0063] Third Embodiment

[0064] The following refers to Figures 16 to 19 Describe the remote operation module according to the third embodiment of the present disclosure. The transmission mechanism of this embodiment includes a connecting rod 43. One end of the connecting rod 43 makes a circular motion around a center O1 under the drive of the actuator 3.

[0065] In one configuration, the transmission mechanism further includes a driving wheel 7 that receives the driving force of the actuator 3. The one end of the connecting rod 43 is connected to the disk of the driving wheel 7 through a pin shaft 71, so as to make a circular motion around the center O1 of the driving wheel 7.

[0066] The other end of the connecting rod 43 has a protruding portion 431 serving as the first force application part. The handle 5 has a sliding groove 52. The protruding portion 431 is placed in the sliding groove 52 and can move within the sliding groove 52. The protruding portion 431 can move to the end of the sliding groove 52 serving as the first force receiving part (see Figure 16 and Figure 17 ).

[0067] In one configuration, the actuator 3 drives the driving wheel 7 to rotate in a first direction ( Figures 16 to 19 the clockwise direction in Figure 16 ). The driving wheel 7 drives the connecting rod 43 to move. At the position shown in Figures 16 to 19 , the protruding portion 431 serving as the first force application part on the connecting rod 43 moves along the sliding groove 52 to the end of the sliding groove 52 serving as the first force receiving part ( Figure 17 the lower end of the sliding groove 52 in Figures 16 to 19 ). As the actuator 3 drives the driving wheel 7 to continue rotating in the first direction, the protruding portion 431 will push the end of the sliding groove 52 serving as the first force receiving part, thereby driving the handle 5 to move to the Figure 17 shown closing position. Once the handle 5 moves to the closing position (i.e., the position where the circuit is connected), when the actuator 3 drives the driving wheel 7 to continue rotating in the first direction, the protruding portion 431 serving as the first force application part moves in a direction away from the end of the sliding groove 52 serving as the first force receiving part, as shown in Figure 18 and Figure 19 .

[0068] In the remote operation module according to the third embodiment, after the handle 5 moves to the closing position, when the actuator 3 continues to drive in the same direction, the first force application part can also automatically move in the direction away from the first force receiving part. Therefore, the remote operation module according to the third embodiment of the present disclosure can also achieve a technical effect similar to that of the first embodiment. At the same time, in the third embodiment, since only one link 43 directly connected to the handle 5 can be used to complete the above-mentioned remote closing operation, the structure is further simplified compared with the first embodiment.

[0069] Fourth Embodiment

[0070] The following will refer to Figures 20 to 23 Describe the remote operation module according to the fourth embodiment of the present disclosure. The transmission mechanism of this embodiment includes a link 44. One end of the link 44 makes a circular motion around a center O1 under the drive of the actuator 3.

[0071] In one configuration, the transmission mechanism further includes a drive wheel 7 that receives the driving force of the actuator 3. The one end of the link 44 is connected to the disk of the drive wheel 7 through a pin shaft 71, so as to make a circular motion around the center O1 of the drive wheel 7.

[0072] The other end of the link 44 has a chute 441. The handle 5 has a protrusion 53 as the first force receiving part. The protrusion 53 is placed in the chute 441 and can move within the chute 441. The protrusion 53 can move to the end of the chute 441 as the first force application part (see Figure 21 and Figure 22 ).

[0073] In one configuration, the actuator 3 drives the drive wheel 7 to rotate in the first direction ( Figures 20 to 23 the clockwise direction in Figures 20 to 23 ). The drive wheel 7 drives the link 44 to move. The end of the chute 441 as the first force application part ( Figure 20 the upper end of the chute in Figure 21 ) moves in the direction close to the protrusion 53 as the first force receiving part (see Figure 21 ). At the position shown in Figure 22The closing position shown. Once the handle 5 moves to the closing position (i.e., the position where the circuit is connected), when the actuator 3 drives the driving wheel 7 to continue rotating in the first direction, the end of the chute 441 as the first force application part moves in a direction away from the protrusion 53 as the first force receiving part, as Figure 22 and Figure 23 shown.

[0074] In the remote operation module according to the fourth embodiment, since after the handle 5 moves to the closing position, when the actuator 3 continues to drive in the same direction, the first force application part can also automatically move in a direction away from the first force receiving part, the remote operation module according to the fourth embodiment of the present disclosure can also achieve a technical effect similar to that of the first embodiment. At the same time, in the fourth embodiment, since only one link 43 directly connected to the handle 5 can be used to complete the above-mentioned remote closing operation, the structure is further simplified compared with the first embodiment.

[0075] It should be noted that in the second to fourth embodiments, the structure for remotely opening the circuit breaker to trip is not shown. However, those skilled in the art know that, similar to that disclosed in the first embodiment, it can also be achieved by using a cam or a link to push a pivotally arranged trip lever, or by using other components to push a pivotally arranged trip lever. In addition, various position sensors or timers for determining the driving position described in the first embodiment can also be applied in the second to fourth embodiments.

[0076] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure. Therefore, all changes and modifications are included within the protection scope of the present application defined by the claims. The present application is defined by the appended claims, and equivalents of these claims are also included.
