Operating mechanism of power switch and power switch

Abstract

This application relates to an operating mechanism and a power switch. The operating mechanism includes a base, an operating component, and a switch element. The base has a switch slot. The operating component includes a driving component, a driven component, and a resilient component. The first ends of the driving component and the driven component are rotatably connected to the base. The two ends of the resilient component are connected to the second ends of the driving component and the driven component, respectively. The switch element is connected to the second end of the driven component. The switch element is movably inserted into the switch slot. When the driving component rotates, it drives the resilient component to rotate. When the resilient component passes the dead point, it drives the driven component to rotate, which in turn drives the switch element to move along the switch slot. During the closing or opening operation, the driving force of the driven component comes from the resilient component. Under the force of the resilient component, the driven component drives the switch element to move. The movement speed of the switch contacts is independent of manual operation.

Description

Technical Field

[0001] This application relates to the field of switching electrical appliances, and more particularly to an operating mechanism and a power switch. Background Technology

[0002] A transfer switch is a common low-voltage electrical appliance, often used in important power distribution applications. It is used to switch between two power sources, ensuring that when the primary power source fails during power supply, the system can quickly switch to the backup power source to guarantee normal power supply to the load.

[0003] In related technologies, when the drive switch is closed, the rotation of the operating linkage assembly compresses the spring to store energy, and the locking element locks the operating linkage assembly in the closed position. When the switch is opened, the locking element is released by the trip button (or the trip coil is closed). At this time, the spring releases energy and quickly drives the operating linkage to rotate to the open position. Combined with the reversing mechanism and the Y-slot feature, the operating linkage assembly is driven to the two directions of the Y-slot when the switch is closed, realizing the reversing function.

[0004] When manually closing the changeover switch, the operating mechanism directly links the switch's contact system to close it, and the spring is compressed during closing to store energy. When opening, the spring's released energy directly drives the operating mechanism to the open position. It can be seen that manual closing always involves human operation. Therefore, when the switch is under load, the contact movement speed during manual closing depends on the speed of human operation. Because the spring force must be overcome, the operation speed is slow, resulting in slow contact movement during closing. This can cause the switch contacts to continuously arc and weld, leading to switch damage and other adverse effects. Utility Model Content

[0020] Furthermore, the electric drive component is an electromagnetic component, and the first end of the electric connector is provided with a movable iron core; when the electromagnetic component is energized, it generates a magnetic field, which drives the movable iron core to move;

[0021] The number of electric drive components is two, and the two electric drive components are located on both sides of the manual connector; the two electric drive components are respectively connected to both sides of the rotating shaft of the manual connector through one electric connector, so that the manual connector rotates in opposite directions.

The first end of the first connecting rod is rotatably connected to the base, the third connecting rod is rotatably connected to the base, and the first end of the third connecting rod is rotatably connected to the manual connector. The two ends of the second connecting rod are respectively connected to the second ends of the first connecting rod and the second ends of the third connecting rod.

[0023] Furthermore, the base includes a base, a first sidewall, and a second sidewall, the first sidewall and the second sidewall being disposed at intervals on the base; the switch slot is formed in the first sidewall; the operating component is located between the first sidewall and the second sidewall;

[0025] The manual connector is located on the side of the second sidewall facing the first sidewall and is rotatably connected to the second sidewall via a manual pivot.

[0026] The second sidewall is provided with two electric arc-shaped holes, which are located on both sides of the manual rotating shaft and are arranged opposite to each other.

[0040] In this application's technical solution, a base provides an installation foundation for the operating components and switching elements; the switch slot guides the movement direction of the switching elements. When a closing operation is required, the driving element is pushed to rotate, which in turn causes the elastic element to rotate around the driven element. Before the elastic element passes the dead point, the torque exerted by the elastic element on the driven element is canceled out by the switching element, which is confined within the switch slot, and the driven element does not rotate. The driving element continues to rotate, and after the elastic element has passed the dead point, the direction of the torque exerted by the elastic element on the driven element reverses. At this point, the driven element moves under the action of the elastic element, thereby driving the switching element to move along the switch slot. The switching element then moves the switch contacts to the closing position to achieve closing. Similarly, when a tripping operation is required, the driving element is pushed in the opposite direction to rotate. This rotation of the driving element causes the elastic element to rotate around the driven element. Before the elastic element passes the dead point, the torque exerted by the elastic element on the driven element is canceled out by the switch element confined within the switch slot, and the driven element does not rotate. The driving element continues to rotate. After the elastic element passes the dead point, the direction of the torque exerted by the elastic element on the driven element reverses. At this point, the driven element moves under the action of the elastic element, thereby driving the switch element to move along the switch slot. The switch element then drives the switch contacts to the tripping position to achieve tripping. In this application, during closing or tripping operations, the driving force of the driven element comes from the elastic element. The driven element drives the switch element to move under the force of the elastic element, and the speed of the switch contacts is independent of manual operation. Attached Figure Description

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0060] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0061] In existing technologies, during manual closing operations, human force is constantly applied to the spring to store energy, and the movement speed of the switch contacts depends on the speed of human operation. To solve this technical problem, this application provides an operating mechanism for a power switch that enables the switch contacts to move using an elastic element, thus making the movement speed of the switch contacts independent of human operation.

[0062] Firstly, Figures 1 to 8 The present application provides an operating mechanism for a power switch, which can be applied to a power switch. The power switch includes switch contacts, and the operating mechanism of the power switch can drive the switch contacts to move in order to achieve closing and opening.

[0063] The operating mechanism of the power switch includes a base 1, an operating component 2, and a switch element 24. The base 1 is provided with a switch slot 1a. The operating component 2 includes an active element 21, a driven element 22, and an elastic element 23. The first end of the active element 21 and the first end of the driven element 22 are rotatably connected to the base 1. The two ends of the elastic element 23 are respectively connected to the second end of the active element 21 and the second end of the driven element 22. The position where the torque of the elastic force of the elastic element 23 on the driven element 22 is zero is defined as the dead point position.

[0064] The switch element 24 is connected to the second end of the driven element 22; the switch element 24 is movably disposed in the switch slot 1a; the switch element 24 is used to connect the switch contact of the power switch;

[0065] When the driving member 21 rotates, it drives the elastic member 23 to rotate; when the elastic member 23 passes the dead point position, the elastic member 23 drives the driven member 22 to rotate, which in turn drives the switching member 24, so that the switching member 24 moves along the switching groove 1a.

[0066] Understandably, the base 1 provides the mounting foundation for the operating component 2 and the switch element 24; the switch slot 1a guides the movement direction of the switch element 24. When a closing operation is required, the driving component 21 is pushed to rotate, and the rotation of the driving component 21 will cause the elastic component 23 to rotate around the driven component 22; before the elastic component 23 passes the dead point position, the torque of the elastic component 23 on the driven component 22 is canceled by the switch element 24 confined within the switch slot 1a, and the driven component 22 will not rotate; the driving component 21 continues to rotate, and after the elastic component 23 rotates to pass the dead point position, the direction of the torque of the elastic component 23 on the driven component 22 is reversed. At this time, the driven component 22 moves under the action of the elastic component 23, thereby driving the switch element 24 to move along the switch slot 1a, and the switch element 24 drives the switch contact to move to the closing position to achieve closing. Similarly, when a tripping operation is required, the driving element 21 is pushed in the opposite direction to rotate. The rotation of the driving element 21 will cause the elastic element 23 to rotate around the driven element 22. Before the elastic element 23 passes the dead point position, the torque of the elastic element 23 on the driven element 22 is canceled by the switch element 24 located in the switch slot 1a, and the driven element 22 will not rotate. The driving element 21 continues to rotate. After the elastic element 23 rotates to pass the dead point position, the direction of the torque of the elastic element 23 on the driven element 22 is reversed. At this time, the driven element 22 moves under the action of the elastic element 23, which in turn drives the switch element 24 to move along the switch slot 1a. The switch element 24 drives the switch contact to move to the tripping position to achieve tripping. In this application, during the closing or tripping operation, the driving force of the driven element 22 comes from the elastic element 23. Under the action of the elastic element 23, the driven element 22 drives the switch element 24 to move. The movement speed of the switch contact is independent of manual operation.

[0067] like Figure 2 As shown, in the technical solution of this embodiment, the base 1 includes a base 11, a first side wall 12 and a second side wall 13, with the first side wall 12 and the second side wall 13 spaced apart from each other on the base 11; the switch slot 1a is formed on the first side wall 12; the operating component 2 is located between the first side wall 12 and the second side wall 13; thus, a suitable space can be provided for the assembly and movement of the operating component 2.

[0068] like Figure 2 As shown, in this embodiment, the base 1 is provided with an assembly shaft 14; the first end of the driving member 21 is rotatably connected to the assembly shaft 14; and the first end of the driven member 22 is rotatably connected to the assembly shaft 14. (See reference) Figure 2 The base 11 is provided with a fixing seat 15, and the fixing seat 15 is used to mount the assembly shaft 14. The fixing seat 15 provides an installation position for the assembly shaft 14, and the assembly shaft 14 enables the coaxial installation of the active component 21, which can ensure the smooth operation of opening and closing operations.

[0069] like Figure 2As shown, in this embodiment, the active component 21 includes an active mounting rod 211 and an active connecting rod 212. One end of the active connecting rod 212 is rotatably connected to the assembly shaft 14, and the other end is connected to the active mounting rod 211. The active connecting rod 212 and the active mounting rod 211 are arranged perpendicularly. The active mounting rod 211 is connected to the elastic component 23. Thus, the active mounting rod 211 provides an installation position for the elastic component 23, and the active connecting rod 212 serves as a connector. To improve the stability of the active component 21, there are two active connecting rods 212, which are spaced apart. Furthermore, to further improve the stability and strength of the active component 21, an active reinforcing rod 213 is provided between the two active connecting rods 212.

[0070] like Figure 2 As shown, in this embodiment, the driven member 22 includes a driven mounting rod 221 and a driven connecting rod 222. One end of the driven connecting rod 222 is rotatably connected to the assembly shaft 14, and the other end is connected to the driven mounting rod 221. The driven connecting rod 222 and the driven mounting rod 221 are arranged perpendicularly. The driven mounting rod 221 is connected to the elastic member 23 and the switching member 24. Thus, the driven mounting rod 221 provides an installation position for the elastic member 23 and the switching member 24, and the driven connecting rod 222 serves as a connector. To improve the stability of the driven member 22, there are two driven connecting rods 222, which are spaced apart. To further improve the stability and strength of the driven member 22, a driven reinforcing rod 223 is provided between the two driven connecting rods 222.

[0071] It should be noted that in some other embodiments, the number of active connecting rods 212 may also be one, three, etc., and the number of driven connecting rods 222 may also be one, three, etc., and there is no limitation here.

[0072] like Figure 2 and Figure 3 As shown, in this embodiment, the switch component 24 includes a switch connecting rod 241 and a switch mounting rod 242. The two ends of the switch connecting rod 241 are rotatably connected to the driven mounting rod 221 and the switch mounting rod 242, respectively. One end of the switch mounting rod 242 is movably inserted into the switch slot 1a. Thus, the rotation of the driven mounting rod 221 can be converted into the translation of the switch mounting rod 242 by the switch connecting rod 241. The switch mounting rod 242 is used to connect the switch contacts, and it is confined within the switch slot 1a. The switch slot 1a guides and limits the movement direction and position of the switch mounting rod 242.

[0073] In this embodiment, a driving device is also included. The driving device is disposed on the base 1 and connected to the driving member 21, and is used to drive the driving member 21 to rotate. In this way, the driving device can provide the force required for the rotation of the driving member 21.

[0074] In some embodiments, the drive device can be an electric device that directly drives the active member 21 to rotate. In other embodiments, the drive device can be a manual device that provides a force-bearing position for the operator to apply force and transmits human power to the active member 21.

[0075] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the driving device includes a manual operation component 3, which includes a manual connector 31 and a manual operation component 32. The manual connector 31 is rotatably connected to the base 1. The manual connector 31 is rotatably connected to the second end of the driving component 21. The manual operation component 32 is connected to the manual connector 31. When the manual operation component 32 is subjected to an external force, it drives the manual connector 31 to rotate, thereby driving the driving component 21 to rotate.

[0076] It is understandable that when the operator manually performs the closing or opening operation, the manual operating component 32 can be applied to the manual operating component 32, which will drive the manual connecting component 31 to rotate, and in turn drive the driving component 21 to rotate.

[0077] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the driving device further includes an automatic operation component 4. The automatic operation component 4 includes an electric drive component 41 and an electric connector 42. The electric drive component 41 is disposed on the base 1; the electric connector 42 is rotatably connected to the base 1; the first end of the electric connector 42 is rotatably connected to the electric drive component 41, and the second end of the electric connector 42 is movably connected to the manual connector 31; wherein, the electric drive component 41 drives one end of the electric connector 42 to move, so as to drive the manual connector 31 to rotate through the second end of the electric connector 42, thereby driving the active component 21 to rotate.

[0078] Understandably, the electric drive unit 41 provides power to drive the electric connector 42 to rotate. The rotating electric connector 42 drives the manual connector 31 to rotate, which in turn drives the drive unit 21 to rotate. In this way, both manual and electric operation modes can be selected. The electric operation will drive the manual connector 31 to rotate, which will also drive the manual operation part to rotate. Since the manual operation part is usually exposed, even in the electric operation mode, the current state of the power switch, whether it is open or closed, can be determined by the position of the manual operation part.

[0079] like Figure 1 and Figure 2 As shown, in this embodiment, the electric drive component 41 is an electromagnetic component, and the first end of the electric connector 42 is provided with a movable iron core 43. When the movable iron core 43 is energized, it generates a magnetic field, causing the movable iron core 43 to move. In one embodiment, the electromagnetic component includes a coil and a fixed iron core. The coil surrounds the fixed iron core. When the coil is energized, it generates a magnetic field, causing the movable iron core 43 to move towards the fixed iron core, thereby driving the electric connector 42 to rotate. In this embodiment, the base 11 is provided with a clearance hole, and the movable iron core 43 is movably positioned corresponding to the clearance hole. The electromagnetic component is located below the base 11, thus achieving a reasonable layout.

[0080] It should be noted that the movable iron core 43 can be movably installed in the fixed sleeve, which is installed on the base 11 and has corresponding clearance holes. The fixed sleeve has openings to facilitate the connection between the movable iron core 43 and the automatic connector, and to provide space for the movement of the automatic connector, thus playing a foolproof role.

[0081] like Figure 1 and Figure 2 As shown, in this embodiment, there are two electric drive units 41, located on both sides of the manual connector 31. Each of the two electric drive units 41 is connected to both sides of the shaft of the manual connector 31 via an electric connector 42, so that the manual connector 31 rotates in opposite directions. Thus, opening and closing operations can be achieved by operating the two electric drive units separately.

[0082] After the first electric drive unit 41 is energized and drives the manual connector 31 to rotate in the first direction and achieves the closing, since the active component 21, driven component 22, elastic component 23 and switch component 24 are in a stable closing state, the first electric connector 42 always presses the first movable iron core 43 against the first fixed iron core, and the first electric drive unit 41 can be de-energized and does not need to be energized continuously.

[0083] When it is necessary to open the circuit breaker, the second electric drive unit 41 is energized to drive the manual connector 31 to rotate in the second direction. After the circuit breaker is opened, since the active component 21, the driven component 22, the elastic component 23 and the switch component 24 are in a stable open state, the second electric connector 42 always presses the second movable iron core 43 against the second fixed iron core. The second electric drive unit 41 can be de-energized and does not need to be energized continuously.

[0084] The first direction and the second direction are opposite.

[0085] like Figure 2As shown, in this embodiment, the electric connector 42 includes a first connecting rod 421, a second connecting rod 422, and a third connecting rod 423. The first end of the first connecting rod 421 is rotatably connected to the base 1, and the third connecting rod 423 is rotatably connected to the base 1, with the first end of the third connecting rod 423 rotatably connected to the manual connector 31. The two ends of the second connecting rod 422 are respectively connected to the second ends of the first connecting rod 421 and the third connecting rod 423. The second connecting rod 422 is connected to a movable iron core 43. It can be understood that by setting the first connecting rod 421 and the third connecting rod 423 to the first side wall 12 and the second side wall 13 respectively, the stability of the electric connector 42 during rotation can be improved.

[0086] The third connecting rod 423 is located on the side of the second side wall 13 away from the first side wall 12, and is rotatably connected to the second side wall 13 via an electric rotating shaft; the first end of the third connecting rod 423 is provided with an electric strip hole 42a;

[0087] The manual connector 31 is located on the side of the second side wall 13 facing the first side wall 12, and is rotatably connected to the second side wall 13 via a manual pivot.

[0088] The second side wall 13 is provided with two electric arc-shaped holes 13a, which are located on both sides of the manual rotating shaft and are arranged opposite to each other.

[0089] The manual connector 31 has two electric positioning pins on the side facing the second side wall 13. The electric positioning pins are movably inserted into the electric arc hole 13a and the electric strip hole 42a.

[0090] Understandably, the electric strip hole 42a provides sufficient movement space for the electric movable pin, thus preventing mistaken insertion. The electric arc hole 13a also provides movement space for the electric movable pin, preventing mistaken insertion. Furthermore, the electric arc hole 13a can also limit the movement of the electric movable pin.

[0091] Two electric arc-shaped holes 13a are located on both sides of the manual rotating shaft, so that the force points of the two electric drive components 41 acting on the manual connecting component 31 are located on both sides of the manual rotating shaft, which can drive the manual rotating component to rotate in opposite directions.

[0092] like Figure 1 and Figure 2As shown, in this embodiment, the technical solution also includes a commutation component 5. The switch slot 1a includes a first slot 1b and a second slot 1c. The first slot 1b and the second slot 1c are arranged at an angle and are connected. The commutation component 5 is movably disposed on the base 1. The commutation component 5 has a first state and a second state. In the first state, the commutation component 5 moves to the position corresponding to the second slot 1c to prevent the switch member 24 from entering the second slot 1c. In the second state, the commutation component 5 moves to the position corresponding to the first slot 1b to prevent the switch member 24 from entering the first slot 1b.

[0093] It is understandable that by setting the reversing component 5, the switching operation of the two power switches can be realized. When the first slot 1b moves, the switching component 24 realizes the closing and opening of the first power switch; when the second slot 1c moves, the switching component 24 realizes the closing and opening of the second power switch.

[0094] like Figure 1 , Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the commutation assembly 5 includes a commutation drive 51, a commutation connector 52, and a commutation plate 53. The commutation drive 51 is disposed on the base 1; the commutation connector 52 is rotatably connected to the base 1; one end of the commutation connector 52 is provided with a commutation positioning hole, and the other end is connected to the commutation drive 51; the commutation plate 53 is rotatably connected to the base 1; the commutation plate 53 is provided with a commutation positioning pin 531, which is movably inserted into the commutation strip hole; wherein, the commutation drive 51 drives the commutation connector 52 to rotate, so as to drive the commutation plate 53 to rotate to block the first groove 1b or the second groove 1c.

[0095] It is understandable that the commutator drive 51 provides power to drive the commutator connector 52 to rotate, which in turn drives the commutator plate 53 to rotate, thereby realizing the automatic switching of the state of the commutator assembly 5.

[0096] In one embodiment, the commutation drive 51 is an electromagnetic component, including a coil and a fixed iron core, and the commutation connector 52 is provided with a movable iron core, which is arranged corresponding to the fixed iron core.

[0097] refer to Figure 3 The rotation center of the commutator plate 53 is directly above the switch slot 1a. The commutator plate 53 extends toward the switch slot 1a to form a pointed part, which shields the first slot 1b or the second slot 1c.

[0098] refer to Figure 8 A limiting groove 1d is provided at the connection between the first groove 1b and the second groove 1c. Whether the reversing assembly 5 is in the first state or the second state, when the switch mounting rod 242 is limited within the limiting groove 1d, both the first power switch and the second power switch are in the open state.

[0099] The width of the first groove 1b is adapted to the size of the switch mounting rod 242, and the width of the second groove 1c is adapted to the size of the switch mounting rod 242.

[0100] Secondly, this application also provides a power switch, including a switch contact and an operating mechanism as described above. The specific structure of the operating mechanism is as described in the above embodiments. Since this power switch adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The switch element 24 of the operating mechanism is connected to the switch contact.

[0101] For example, a dual power switch is a type of power switch that includes a first power switch and a second power switch. The switching contacts enable the closing and opening of either the first or second power switch, allowing switching between the first and second power supplies. The operation of the dual power switch is analyzed below with reference to the accompanying drawings.

[0102] refer to Figure 3 In the initial state, the switch mounting rod 242 is confined within the limiting groove 1d, and the commutator plate 53 blocks the second groove 1c. At this time, the first power supply can be used, and by operating the operating component 2, closing and opening of the circuit breaker can be achieved, thus disconnecting and connecting the first power supply. (Reference) Figure 3 The driving member 21, the driven member 22, and the elastic member 23 form a triangular structure. The elastic member 23 has a tendency to rotate the driven member 22 in a clockwise direction, and the driven member 22 remains stationary due to the limiting effect of the limiting groove 1d on the switching member 24.

[0103] When the first power supply needs to be closed, the first electric drive unit 41 is energized, causing the first movable iron core 43 to move downwards, which in turn causes the first electric connector 42 to rotate, and drives the manual connector 31 to rotate clockwise, thereby driving the driving member 21 to rotate clockwise. Before the elastic member 23 passes the dead point position, the torque direction of the elastic member 23 on the driven member 22 is clockwise, and the driven member 22 remains stationary under the restriction of the switch member 24. After the elastic member 23 passes the dead point position, refer to... Figure 4 When the torque direction of the elastic element 23 on the driven element 22 changes to a counterclockwise direction, the driven element 22 rotates counterclockwise under the elastic force of the elastic element 23, and drives the switch element 24 to move along the first groove 1b until it moves to the limit position of the first groove 1b. Figure 5 At this time, the switch component 24 drives the switch contact to the closed position, completing the closing operation.

[0104] When the first power supply needs to be tripped, the second electric drive unit 41 is energized, causing the second movable iron core 43 to move downwards, which in turn causes the second electric connector 42 to rotate, and drives the manual connector 31 to rotate counterclockwise, thereby driving the drive unit 21 to rotate counterclockwise. Before the elastic element 23 passes the dead point position, the torque direction of the elastic element 23 on the driven element 22 is counterclockwise, and the driven element 22 remains stationary under the restriction of the switch unit 24. After the elastic element 23 passes the dead point position, refer to... Figure 4 When the torque direction of the elastic element 23 on the driven element 22 changes to the clockwise direction, the driven element 22 rotates clockwise under the action of the elastic force of the elastic element 23, and drives the switch element 24 to move along the first groove 1b until it moves to the limit groove 1d. At this time, the switch element 24 drives the switch contact to move to the open position, and completes the open operation.

[0105] When the second power supply needs to be closed, the commutator drive 51 is energized, causing the moving iron core to move downwards, which in turn causes the commutator connector 52 to rotate clockwise, and drives the commutator plate 53 to rotate clockwise, thus blocking the first slot 1b. At this time, the second power supply can be used, and the operation component 2 can be operated to achieve closing and opening, thereby disconnecting and connecting the second power supply. (Reference) Figure 6 The driving member 21, the driven member 22, and the elastic member 23 form a triangular structure. The elastic member 23 has a tendency to rotate the driven member 22 in a clockwise direction, and the driven member 22 remains stationary due to the limiting effect of the limiting groove 1d on the switching member 24.

[0106] When the second power supply needs to be closed, the first electric drive unit 41 is energized, causing the first movable iron core 43 to move downwards, which in turn causes the first electric connector 42 to rotate, and drives the manual connector 31 to rotate clockwise, thereby driving the driving unit 21 to rotate clockwise. Before the elastic element 23 passes the dead point position, the torque direction of the elastic element 23 on the driven element 22 is clockwise, and the driven element 22 remains stationary under the restriction of the switch element 24. After the elastic element 23 passes the dead point position, refer to... Figure 4 When the torque direction of the elastic element 23 on the driven element 22 changes to a counterclockwise direction, the driven element 22 rotates counterclockwise under the elastic force of the elastic element 23, and drives the switch element 24 to move along the second groove 1c until it moves to the limit position of the second groove 1c. (Refer to...) Figure 7 At this time, the switch component 24 drives the switch contact to the closed position, completing the closing operation.

[0107] When the second power supply needs to be tripped, the second electric drive unit 41 is energized, causing the second movable iron core 43 to move downwards, which in turn causes the second electric connector 42 to rotate and the manual connector 31 to rotate counterclockwise, thereby causing the drive unit 21 to rotate counterclockwise. Before the elastic element 23 passes the dead point, the torque of the elastic element 23 on the driven element 22 is counterclockwise, and the driven element 22 remains stationary under the restriction of the switch unit 24. After the elastic element 23 passes the dead point, the torque of the elastic element 23 on the driven element 22 changes to clockwise. At this time, the driven element 22 rotates clockwise under the elastic force of the elastic element 23, and causes the switch unit 24 to move along the second groove 1c until it moves to the limit groove 1d. At this time, the switch unit 24 causes the switch contact to move to the tripped position, completing the tripping operation.
