Description

Technical Field

[0001] This application relates to the field of switches, specifically to a disconnection control system and a disconnection control method thereof. Background Technology

[0002] In recent years, with the rapid development of the power industry and the dramatic increase in social electricity consumption, the market has placed higher demands on electrical switches: safety and reliability, miniaturization, modularity, large capacity, and long lifespan. Achieving large capacity while miniaturizing greatly increases the technical difficulty of electrical switches. This difficulty is not only reflected in the higher requirements for the materials of each component in the switch, but also in the more stringent requirements for the switch's safe load-bearing capacity and reliable breaking capacity.

[0003] Common electrical switches typically include a stationary contact conductive component and a movable contact conductive component. The stationary contact conductive component includes at least one stationary contact, and the movable contact conductive component includes at least one movable contact. The movable contact conductive component can be controlled to move relative to the stationary contact conductive component, allowing its movable contact to switchably engage or disengage with the stationary contact of the stationary contact conductive component, thereby switching the electrical switch between a closed state and an open state.

[0004] In power systems, as the voltage or current in a circuit increases, the electrical tripping process generates a larger electric arc. If the arc exceeds a certain limit, it can burn out the electrical switch or cause it to malfunction. Therefore, it is necessary to extinguish the arc quickly during the tripping process to ensure the safe breaking capacity of the electrical switch under predetermined voltage and current.

[0005] Several technical means exist to improve the safe breaking capacity of electrical switches, such as increasing the diameter of the moving contact conductive element, adding a magnet to guide the arc, and adding an arc-extinguishing grid. These methods primarily achieve rapid arc extinguishing by lengthening the arc, thereby enabling the safe breaking of the electrical switch. However, these technical means all increase the cost or size of the electrical switch.

[0006] Therefore, an optimized disconnection control scheme is needed. Summary of the Invention

[0007] One advantage of this application is that it provides a disconnection control system and a disconnection control method thereof. The disconnection control system is applicable to electrical switches and can provide a large driving force to the movable contact conductive component of the electrical switch during the disconnection process, thereby increasing the movement speed of the movable contact conductive component and improving the safe disconnection capability of the electrical switch.

[0008] Another advantage of this application is that it provides a disconnection control system and a disconnection control method thereof, wherein the disconnection control system is equipped with an elastic disconnection auxiliary element for its energy storage element. The elastic disconnection auxiliary element can provide a driving force in the same direction as the energy storage element to a driven member suitable for connection to the movable contact conductive assembly during the opening of the electrical switch, so as to increase the movement speed of the driven member, and thereby increase the movement speed of the movable contact conductive assembly.

[0009] Another advantage of this application is that it provides a disconnection control system and a disconnection control method thereof, wherein the elastic disconnection auxiliary element of the disconnection control system can selectively regulate the unlocking resistance of the electrical switch and the driving force on the conductive component of the movable contact during the closing and opening processes. For example, during the closing control process, it only stores energy and does not release energy, and during the opening control process, it only releases energy and does not store energy again, so that the unlocking resistance of the disconnection control system during the opening control process is less than that during the closing control process, and the driving force provided during the opening control process is greater than that provided during the closing control process. That is, while reducing the unlocking resistance of the disconnection control system during the opening control process, it increases the driving force provided by the disconnection control system during the opening control process.

[0010] Another advantage of this application is that it provides a disconnection control system and a disconnection control method thereof, wherein, compared with traditional electrical switches, under the same disconnection speed requirement, the size of the energy storage element of this application is smaller, and the size of the components that cooperate with the energy storage element, such as the locking structure, is also reduced accordingly.

[0011] Another advantage of this application is that it provides a disconnection control system and a disconnection control method thereof. Since the energy storage element of the disconnection control system is small in size, the driving force for driving the energy storage element to store energy will be reduced. The energy storage element is driven to move by the driving component. Correspondingly, the driving force for driving the driving component to move will be reduced. In this way, it is more labor-saving to operate the disconnection control system.

[0012] Another advantage of this application is that it provides a disconnection control system and a disconnection control method thereof, wherein the disconnection control system can improve the safe disconnection capability of the electrical switch without significantly increasing its overall size or without increasing its overall size, thereby achieving improved safe disconnection capability and miniaturization compatibility.

[0055] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0056] Application Overview As mentioned above, in power systems, when the voltage or current in a circuit increases, the electrical tripping process generates a larger electric arc. If the generated arc exceeds a certain limit, it can cause the electrical switch to burn out or malfunction. Therefore, it is necessary to extinguish the arc quickly during the tripping process to ensure the safe breaking capacity of the electrical switch under predetermined voltage and current.

[0057] Several technical means exist to improve the safe breaking capacity of electrical switches, such as increasing the diameter of the moving contact conductive element, adding a magnet to guide the arc, and adding an arc-extinguishing grid. These methods primarily achieve rapid arc extinguishing by lengthening the arc, thereby enabling the safe breaking of the electrical switch. However, these technical means all increase the cost or size of the electrical switch.

[0058] Therefore, an optimized disconnection control scheme is needed.

[0059] Theoretically, in electrical switches, within a certain speed range, the faster the movable contact conductive component rotates, the faster the arc is broken. Therefore, the arc-extinguishing speed can be increased by accelerating the movement speed of the movable contact conductive component during the opening process of the electrical switch, thereby improving the safe breaking capability of the electrical switch. Furthermore, the movement speed of the movable contact conductive component can be increased by increasing the driving force on it during the opening process of the electrical switch.

[0060] In existing electrical switches, the driving force for the movable contact conductive assembly is mainly provided by the energy storage spring when it releases energy. Specifically, before closing, the mounting base with the energy storage spring is locked in a first locked position by a locking structure. During the closing process, one end of the energy storage spring is driven, and the energy storage spring stores energy. Then, the energy storage spring acts on the mounting base, causing the mounting base to unlock from the first locked position. The energy storage spring releases energy, driving the mounting base to move, which in turn moves the movable contact assembly towards the stationary contact conductive assembly. Then, the mounting base is locked in a second locked position by the locking structure, and the electrical switch remains in the closed state. During the opening process, the other end of the energy storage spring is driven in the reverse direction, and the energy storage spring stores energy. Then, the energy storage spring acts on the mounting base, causing the mounting base to unlock from the second locked position. The energy storage spring releases energy, driving the mounting base to move, which in turn moves the movable contact away from the stationary contact. Then, the mounting base is locked in a first locked position by the locking structure, and the electrical switch remains in the open state.

[0061] The inventors of this application propose to configure an elastic breaking auxiliary element for the energy storage spring, which releases energy together with the energy storage spring during the opening process. After the mounting base is unlocked from the second locking position, the auxiliary element jointly drives the mounting base to move, thereby driving the movable contact conductive component to move and increasing the movement speed of the movable contact conductive component, so as to improve the safe breaking capability of the electrical switch.

[0062] It is worth mentioning that in existing electrical switches, energy is stored and unlocked by driving one end of the energy storage spring during both the closing and opening processes. The energy storage spring releases energy to provide the driving force for the movable contact assembly. The driving force provided by the energy storage spring during the opening and closing processes is the same, and the driving force on the energy storage spring during energy storage is basically the same as the driving force provided during energy release. This makes the unlocking resistance during closing and the unlocking resistance during opening the same, and the closing speed and opening speed are the same. This can easily lead to a misconception: since the unlocking resistance during closing and the unlocking resistance during opening of the electrical switch are the same, the closing speed and the opening speed must also be the same. Increasing the opening speed must necessarily increase the closing speed, and at the same time, increasing the opening speed means increasing the unlocking resistance.

[0063] In reality, the existing structural design of electrical switches results in the unlocking resistance during closing being consistent with the unlocking resistance during opening, the closing speed being consistent with the opening speed, and the unlocking resistance increasing while the opening speed is increased. Specifically, the closing and opening processes of existing electrical switches are achieved by the same energy storage spring storing and releasing energy. The energy stored in the energy storage spring during closing is consistent with the energy stored during opening, and the energy released during opening is consistent with the energy released during opening, resulting in consistent closing performance (e.g., closing speed, closing unlocking resistance) and opening performance (e.g., opening speed, opening unlocking resistance). The existing structural design limits the independence of the energy storage mode and the energy release mode between the closing and opening processes. In such a structural design, the increase in closing speed is a byproduct of the increase in opening speed.

[0064] People often overlook the fact that there is no necessary correlation between the energy storage and energy release modes during the closing and opening processes. By adjusting the structure of the electrical switch, the closing speed and opening speed can be different.

[0065] It should be noted that the main factor affecting the breaking performance of electrical switches is the opening speed. This application can introduce a control factor to regulate the opening and closing processes, increasing only the opening speed. In this application, the elastic breaking auxiliary element can be used as this control factor to regulate the opening and closing processes. Specifically, the elastic breaking auxiliary element is designed to store energy without releasing it during the closing process and to release energy without storing it again during the opening process, thereby increasing the opening speed and reducing the unlocking resistance during opening.

[0066] Based on this, this application proposes a disconnection control system, comprising: a disconnection control system including a fixing member, a driven member movably mounted on the fixing member, an energy storage element, a flexible disconnection auxiliary element, and a drive assembly, wherein the drive assembly is adapted to be driven to control the disconnection control system to selectively enter a closing process or a disconnection process. In the closing process, the energy storage element and the flexible disconnection auxiliary element are controlled to store energy, and the energy storage element releases energy. In the disconnection process, the energy storage element is controlled to store energy, and the energy storage element and the flexible disconnection auxiliary element release energy. In this way, the driving force on the driven member during the disconnection process is increased, thereby improving the safe disconnection capability of the electrical switch.

[0067] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0068] Indicative Disconnection Control System like Figures 1 to 17As shown, the disconnection control system according to an embodiment of this application is illustrated, providing a disconnection control scheme for an electrical switch. The disconnection control system regulates the closing and opening processes of its energy storage element 30 by configuring a resilient disconnection auxiliary element 40, thereby increasing the driving force on the conductive components of the movable contact of the electrical switch during the opening process and thus increasing the electrical safety disconnection capability. In this application, the closing control process of the disconnection control system corresponds to the closing process of the electrical switch to which it is applied, and the opening control process of the disconnection control system corresponds to the opening process of the electrical switch to which it is applied.

[0069] Specifically, the electrical switch to which the disconnection control system according to the embodiments of this application is applied is provided with a stationary contact conductive component and a movable contact conductive component. The stationary contact conductive component includes at least one stationary contact, and the movable contact conductive component includes at least one moving contact. The disconnection control system is adapted to control the movement of the movable contact conductive component relative to the stationary contact conductive component during its closing control process, such that the moving contact of the movable contact conductive component moves towards the stationary contact of the stationary contact conductive component and engages with the stationary contact; or, during the opening control process, the movable contact conductive component is controlled to move relative to the stationary contact conductive component, such that the moving contact of the movable contact conductive component moves away from the stationary contact of the stationary contact conductive component and separates from the stationary contact. During the opening control process, an electric arc will be generated between the moving contact and the stationary contact. Within a certain range of movement speed, the faster the movement speed of the moving contact relative to the stationary contact, the faster the arc extinguishing speed, and the higher the safe disconnection capability of the switch. In the disconnection control system of this application embodiment, the disconnection control system can provide a large driving force to the movable contact conductive component during the disconnection control process, thereby increasing the movement speed of the movable contact conductive component relative to the stationary contact during the disconnection process, and thus improving the safe disconnection capability of the electrical switch.

[0070] More specifically, the disconnection control system includes a fixing member 10A, a driven member 20, an energy storage element 30, an elastic disconnection auxiliary element 40, and a drive assembly 50. The fixing member 10A is provided with a first locking head 13 and a second locking head 14. The driven member 20 is movably mounted on the fixing member 10A and is adapted to be connected to the movable contact conductive assembly of the electrical switch. The driven member 20 is provided with at least one locking structure 22, at least one of which is adapted to cooperate with the first locking head 13 to lock the driven member 20 in a first position P1, and at least one of which is adapted to cooperate with the second locking head 14 to lock the driven member 20 in a second position P2. The energy storage element 30 is mounted on the driven member 20, and both ends of the energy storage element 30 are adapted to be driven by the drive assembly 50. At least one end of the elastic disconnection auxiliary element 40 is adapted to be driven by the drive assembly 50. It should be understood that the elastic disconnection auxiliary element 40 is elastic and can also store and release energy. The drive assembly 50 is adapted to be driven to selectively enter either a closing control process or a opening control process of the tripping control system. During the closing control process, the drive assembly 50 is driven to rotate in a first direction, controlling at least one of the energy storage element 30 and the elastic tripping auxiliary element 40 to store energy and release energy, thereby driving the driven member 20 to rotate in the first direction. During the opening control process, the drive assembly 50 is driven to rotate in a second direction, controlling at least one of the energy storage element 30 and the elastic tripping auxiliary element 40 to store energy and release energy, thereby driving the driven member 20 to rotate in the second direction. In this way, a larger driving force is provided to the driven member 20 during the opening control process.

[0071] It is worth mentioning that the energy storage mode of the energy storage element 30 and the elastic disconnection auxiliary element 40 in the closing control process may be inconsistent with their energy storage mode in the opening control process, and the energy release mode of the energy storage element 30 and the elastic disconnection auxiliary element 40 in the closing control process may also be inconsistent with their energy release mode in the opening control process.

[0072] In this embodiment, the energy storage and release modes during the opening and closing control processes can be adjusted using the elastic breaking auxiliary element 40. Considering that the main factor affecting the breaking performance of an electrical switch is the opening speed, the elastic breaking auxiliary element 40 can be designed to only store energy and not release energy during the closing control process, and only release energy and not store energy again during the opening control process. In this way, the unlocking resistance of the breaking control system during the opening control process is less than that during the closing control process, and the driving force provided during the opening control process is greater than that provided during the closing control process. That is, while reducing the unlocking resistance of the breaking control system during the opening control process, the driving force provided by the breaking control system during the opening control process is increased.

[0073] Here, the unlocking resistance is the same as the driving force required to precisely transition the driven member 20 from the locked state to the unlocked state. During the closing control process, the unlocking resistance is the same as the driving force required to precisely unlock the driven member 20 from the first position P1. During the opening control process, the unlocking resistance is the same as the driving force required to precisely unlock the driven member 20 from the second position P2. Furthermore, the unlocking resistance is the same as the force required to drive the drive assembly 50. When the drive assembly 50 is manually driven, the unlocking resistance will be related to the force provided by the operator when operating the disconnection control system; the smaller the unlocking resistance, the less effort is required for manual operation.

[0074] It should be understood that the specific structural design scheme that can meet the requirement that the elastic disconnection auxiliary element 40 only stores energy and does not release energy during the closing control process, and only releases energy and does not store energy again during the opening control process is not limited to this application. Different examples that meet this requirement will be shown below.

[0075] Example 1 In one example of this application, such as Figure 2As shown, the tripping control system includes a fixed component 10A, a driven component 20, an energy storage element 30, a flexible tripping auxiliary element 40, and a drive assembly 50. In this specific example, the drive assembly 50 is adapted to be driven to selectively enter a closing control process or a tripping control process. During the closing control process, the drive assembly 50 is driven to rotate in a first direction, controlling the energy storage element 30 and the flexible tripping auxiliary element 40 to store energy, and the energy storage element 30 to release energy, thereby driving the driven component 20 to rotate in the first direction. During the tripping process, the drive assembly 50 is driven to rotate in a second direction, controlling the energy storage element 30 to store energy, and the energy storage element 30 and the flexible tripping auxiliary element 40 to release energy, thereby driving the driven component 20 to rotate in the second direction. The first direction and the second direction are opposite. In this example, the first direction is clockwise, and the second direction is counterclockwise. In a modified embodiment of this application, the first direction may be designed to be counterclockwise and the second direction to be clockwise.

[0076] In this embodiment, the disconnection control system has a rotation axis L. The rotatable components of the disconnection control system, such as the driven member 20 and the drive assembly 50, rotate about the rotation axis L during rotation. That is, the rotation axis L of the rotatable components of the disconnection control system is aligned with the rotation axis L of the disconnection control system. The axial direction Z of the disconnection control system is aligned with the extension direction of its rotation axis L, and the radial direction R of the disconnection control system is perpendicular to its axial direction Z. The axial direction of each component of the disconnection control system is aligned with the axial direction Z of the disconnection control system, and the radial direction R of each component of the disconnection control system is aligned with the radial direction R of the disconnection control system.

[0077] In the embodiments of this application, "inner" refers to the direction pointing towards the middle of the disconnection control system in the radial direction R, and "outer" refers to the direction away from the middle of the disconnection control system in the radial direction R.

[0078] The fixing member 10A includes an actuating housing 11, a cover 15, a first limiting seat 12, a first locking head 13, and a second locking head 14. The actuating housing 11 has a receiving cavity 101, which includes a first mounting space 1011 and a second mounting space 1012. The first mounting space 1011 is located in the middle of the actuating housing 11, and the second mounting space 1012 is located around the first mounting space 1011. Specifically, the actuating housing 11 includes a housing base plate 111, a housing peripheral wall 112 extending upward from the outer edge of the housing base plate 111, and an inner annular wall 113 extending upward from the middle of the housing base plate 111. The inner annular wall 113 divides the space of the receiving cavity 101 into a first mounting space 1011 and a second mounting space 1012. The housing bottom plate 111 and the inner annular wall 113 enclose the first mounting space 1011, and the space between the inner annular wall 113 and the housing peripheral wall 112 forms an annular second mounting space 1012 surrounding the first mounting space 1011. Figure 2 and Figure 3 As shown.

[0079] In this example, such as Figure 1 As shown, the cover 15 covers the actuating housing 11. The first limiting seat 12 is installed in the first mounting space 1011 of the actuating housing 11, and the elastic breaking auxiliary element 40 is installed in the second mounting space 1012 of the actuating housing 11. Specifically, the first limiting seat 12 is positioned on the actuating housing 11, wherein the positioning method is not limited to this application, for example, snap-fit ​​positioning, welding, etc.

[0080] In one embodiment of this application, the first limiting seat 12 is positioned on the actuating housing 11 by a snap-fit ​​positioning method. For example... Figure 2 and Figure 3As shown, the base plate 111 of the actuating housing 11 has at least one positioning boss 1111 protruding from its inner surface. The first limiting seat 12 includes a first base plate 121, which has at least one positioning groove 1201 recessed upward from its bottom surface. The positioning boss 1111 is adapted to engage with the positioning groove 1201, so that the first limiting seat 12 is positioned on the base plate 111 of the actuating housing 11. The positioning groove 1201 can be implemented as a through groove, that is, a positioning groove 1201 extending from the bottom surface of the first limiting seat 12 to its upper surface. The positioning groove 1201 can also be configured as a non-through groove. The height of the positioning boss 1111 is greater than or equal to the depth of the positioning groove 1201, or it can be less than the depth of the positioning groove 1201.

[0081] The elastic breaking auxiliary element 40 has a helical spring structure and is sleeved on the inner ring wall 113. The elastic breaking auxiliary element 40 utilizes the space of the actuating housing 11 itself, which can improve the breaking capacity of the electrical switch without significantly increasing its overall size, thereby improving the safe breaking capacity of the breaking control system and achieving miniaturization compatibility.

[0082] The actuating housing 11 further includes a hollow shaft 114 penetrating the upper and lower surfaces of the housing base plate 111. In this example, at least a portion of the hollow shaft 114 extends upward from the upper surface of the housing base plate 111. The first base plate 121 has a first central through hole 1202 formed in the middle, through which the hollow shaft 114 can pass, such that the first limiting seat 12 is sleeved on the hollow shaft 114 of the actuating housing 11. It should be understood that the upper end of the hollow shaft 114 may also be flush with the housing base plate 111.

[0083] like Figure 3 As shown, the first limiting seat 12 further includes a first limiting structure 122 disposed on the first base plate 121 for defining one end of the elastic breaking auxiliary element 40. In this example, the first limiting structure 122 extends upward from the first base plate 121 as a whole. The first limiting structure 122 includes a limiting upper extension 1222 extending upward from the first base plate 121 and a limiting bending portion 1223 extending outward from the limiting upper extension 1222 in a radial direction R set by the breaking control system. The limiting bending portion 1223 forms the end of the first limiting structure 122.

[0084] The first locking head 13 and the second locking head 14 are used to limit the rotation angle of the driven member 20 and the drive assembly 50, and can lock the driven member 20 in a first position P1 or a second position P2. Figure 3 As shown, in this example, the first lock head 13 and the second lock head 14 extend upward from the first base plate 121 of the first limiting seat 12. The first lock head 13 is located at a first position P1 of the first limiting seat 12, and the second lock head 14 is located at a second position P2 of the first limiting seat 12. The height at which the first lock head 13 extends upward relative to the first base plate 121 is the same as the height at which the second lock head 14 extends upward relative to the first base plate 121. The height at which the first limiting structure 122 extends upward relative to the first base plate 121 is greater than the height at which the first lock head 13 extends upward relative to the first base plate 121. The first limiting structure 122 and the first lock head 13 form an angle with respect to the center of the first base plate 121, and the angle is small, greater than 0 degrees and less than 90 degrees. The angle between the first lock head 13 and the second lock head 14 and the center of the first base plate 121 is close to 180 degrees.

[0085] The first lock head 13 includes a first upper extension 131 extending upward from the first base plate 121 and a first bent portion 132 extending outward from the first upper extension 131 in a radial direction R set by the disconnection control system, the first bent portion 132 forming the end of the first lock head 13. The second lock head 14 includes a second upper extension 141 extending upward from the first base plate 121 and a second bent portion 142 extending outward from the second upper extension 141 in a radial direction R set by the disconnection control system, the second bent portion 142 forming the end of the second lock head 14.

[0086] It is worth mentioning that, in other examples of this application, the first lock head 13, the second lock head 14, and the first limiting structure 122 can be implemented with other structural features. For example, in other examples of this application, the first lock head 13 and / or the second lock head 14 can not only limit the rotation angle of the driven member 20 and the drive assembly 50, but can also be used as a first limiting structure 122 defining one end of the elastic breaking auxiliary element 40, without the need to provide an additional limiting structure for defining one end of the elastic breaking auxiliary element 40. That is, the first lock head 13 and / or the second lock head 14 form a first limiting structure 122 for defining one end of the elastic breaking auxiliary element 40.

[0087] It is also worth mentioning that, in a modified embodiment of this application, the first limiting seat 12 may be integrally formed on the actuating housing 11, and the first base plate 121 of the first limiting seat 12 may be implemented as part of the housing base plate 111 of the actuating housing 11. Accordingly, the first limiting structure 122 extends upward from a specific position on the housing base plate 111, the first locking head 13 extends upward from a first position P1 on the housing base plate 111, and the second locking head 14 extends upward from a second position P2 on the housing base plate 111.

[0088] In particular, the process of forming the actuating housing 11 with the first lock head 13, the second lock head 14, and the first limiting structure 122 using an integral molding process is relatively complex. Therefore, preferably, after the first limiting seat 12, the first lock head 13, and the second lock head 14 are integrally formed into the first limiting member, the first limiting seat 12 is positioned on the actuating housing 11, which simplifies the process. In addition, when the first limiting seat 12 and the first limiting seat 13 are separate structures, it is convenient to replace or adjust the first limiting seat 12.

[0089] The driven member 20 is rotatably mounted on the fixed member 10A. For example... Figure 4As shown, the driven member 20 includes a second limiting seat 21, at least one locking structure 22 disposed on the second limiting seat 21, a first central rotating shaft 23 disposed on the second limiting seat 21, and a bushing 24 sleeved on the first central rotating shaft 23. The second limiting seat 21 includes a second base plate 211 and at least one limiting arm extending upward from the second base plate 211, wherein the second base plate 211 has a second central through hole 2101 located in its middle. The first central rotating shaft 23 includes a chuck 233, a first rotating shaft portion 231 extending downward from the chuck 233, and a second rotating shaft portion 232 extending upward from the chuck 233. The first central rotating shaft 23 can be mounted on the second base plate 211 through the second central through hole 2101, wherein the second rotating shaft portion 232 can extend above the second base plate 211 through the second central through hole, and the first rotating shaft portion 231 is limited to below the second base plate 211. The first rotating shaft portion 231 is rotatably connected to the fixing member 10A, passes through the first central through hole 1202 of the first limiting seat, and is sleeved on the hollow shaft 114 of the actuating housing 11. The first rotating shaft portion 231 is adapted to be connected to the movable contact conductive assembly of the electrical switch, thereby driving the driven member 20 to move when driven. The second rotating shaft portion 232 has a hollow structure for drivingly connecting the drive assembly 50. The bushing 24 is fastened to the second rotating shaft portion 232 of the first central rotating shaft 23 and has a hollow structure corresponding to the hollow structure of the second rotating shaft portion 232.

[0090] like Figure 5As shown, the second base plate 211 includes a base plate body 2111 and a protrusion 2112 protruding outward from the outer edge of the base plate body 2111. During the rotation of the second limiting seat 21, the protrusion 2112 protrudes from or is flush with the outer periphery of the first position P1 of the first limiting seat 12 (i.e., the outer periphery of the first limiting seat 12 at the position where the first lock head 13 is located), or the outer periphery of the second position P2 of the first limiting seat 12 (i.e., the outer periphery of the first limiting seat 12 at the position where the second lock head 14 is located), so that when the second limiting seat 21 is rotated to the first position P1 of the first limiting seat 12, the protrusion 2112 abuts against the first lock head 13, or when the second limiting seat 21 is rotated to the second position P2 of the first limiting seat 12, the protrusion 2112 abuts against the second lock head 14, thereby controlling the rotation angle of the second limiting seat 21.

[0091] Specifically, the protrusion 2112 has a first side edge 21121, a second side edge 21122, and a peripheral edge 21122 extending between the first side edge 21121 and the second side edge 21122, wherein the first side edge 21121 and the second side edge 21122 extend outward from the base plate body 2111 in the radial direction R of the disconnection control system. In this example, the first direction is clockwise, the second direction is counterclockwise, and the protrusion 2112 extends from the first side edge 21121 in a counterclockwise direction to the second side edge 21122, with the first side edge 21121 located in the clockwise direction of the second side edge 21122. The first side edge 21121 is adjacent to the first lock head 13, and the second side edge 21122 is adjacent to the second lock head 14.

[0092] The first side edge 21121 is flush with or protrudes from the outer edge of the first limiting seat 12 where the first lock head 13 is located, and further flush with or protrudes from the first lock head 13 in the radial direction R set by the disconnection control system. The second side edge 21122 is flush with or protrudes from the outer edge of the first limiting seat 12 where the second lock head 14 is located, and further flush with or protrudes from the second lock head 14 in the radial direction R set by the disconnection control system.

[0093] During the rotation of the driven member 20 in the first direction, when the protrusion 2112 reaches the first position P1 of the first limiting seat 12, the first side edge 21121 of the protrusion 2112 abuts against the side edge of the first lock head 13. During the rotation of the driven member 20 in the second direction, when the protrusion 2112 reaches the second position P2 of the first limiting seat 12, the second side edge 21122 of the protrusion 2112 abuts against the side edge of the second lock head 14.

[0094] It should be understood that when the first direction is counterclockwise and the second direction is clockwise, the protrusion 2112 extends from the first side edge 21121 in a clockwise direction to the second side edge 21122, and the first side edge 21121 is located in the counterclockwise direction of the second side edge 21122.

[0095] The second limiting seat 21 includes a first limiting arm 212 and a second limiting arm 213 extending upward from the second base plate 211. The first limiting arm 212 is used to limit both ends of the energy storage element 30, and the second limiting arm 213 is used to limit one end of the elastic breaking auxiliary element 40. The width of the first limiting arm 212 is greater than the width of the second limiting arm 213, and the second limiting arm 213 extends upward from the protrusion 2112 of the second base plate 211. It should be understood that in other embodiments, the widths of the first limiting arm 212 and the second limiting arm 213 may also be implemented in other configuration relationships, for example, the widths may be the same, or the width of the first limiting arm 212 may be greater than the width of the second limiting arm 213.

[0096] The energy storage element 30 has a first end 31, a second end 32, and a first elastic body 33 extending between the first end 31 and the second end 32. The energy storage element 30 is sleeved on the bushing 24 of the second limiting seat 21. The first end 31 and the second end 32 of the energy storage element 30 are movably disposed on the driven member 20. When the disconnection control system is in the initial state, the first end 31 and the second end 32 of the energy storage element 30 are located on both sides of the first limiting arm 212. In this example, the first limiting arm 212 has a first limiting groove 2121 on one side and a second limiting groove 2122 on the other side. The first limiting groove 2121 is used to hold the first end 31 of the energy storage element 30, and the second limiting groove 2122 is used to hold the second end 32 of the energy storage element 30 to prevent the energy storage element 30 from slipping off.

[0097] In this embodiment, the initial state of the disconnection control system is: the drive component 50 of the disconnection control system is not driven, and the locking structure 22 of the driven member 20 and the first lock head 13 of the fixed member 10A are locked together. The initial state of each component in the disconnection control system is the state of each component when the disconnection control system is in its initial state. For example, the initial state of the energy storage element 30 is: the drive component 50 of the disconnection control system is not driven, and the locking structure 22 of the driven member 20 and the first lock head 13 of the fixed member 10A are locked together. The initial state of the elastic disconnection auxiliary element 40 is: the drive component 50 of the disconnection control system is not driven, and the locking structure 22 of the driven member 20 and the first lock head 13 of the fixed member 10A are locked together.

[0098] The energy storage element 30 has a spiral structure, such as Figure 7 As shown, the energy storage element 30 extends from its second end 32 along its first elastic body 33 in a first rotational direction to the second end 32 in the first rotational direction. For example, when the first rotational direction is clockwise, the energy storage element 30 extends from its second end 32 along its first elastic body 33 in a clockwise direction to the first end 31 located in the clockwise direction of the second end 32; when the first rotational direction is counterclockwise, the energy storage element 30 extends from its second end 32 along its first elastic body 33 in a counterclockwise direction to the first end 31 located in the counterclockwise direction of the second end 32.

[0099] During the stretching process of the energy storage element 30, the energy storage element 30 is in an energy storage state. During the return of the energy storage element 30 from the stretched state to the initial state, the energy storage element 30 is in a energy dissipation state. In this example, the first rotation direction is consistent with the rotation direction of the drive assembly 50 during the closing control process of the disconnection control system, that is, the first direction. During the closing control process of the disconnection control system, when the driven member 20 and the fixed member 10A are locked together, the first end 31 of the energy storage element 30 is driven by the drive assembly 50 to move along the first direction from its initial position (i.e., one side of the first limit arm), and the energy storage element 30 is stretched and enters the energy storage state; when the driven member 20 and the fixed member 10A are unlocked, the first end 31 of the energy storage element 30 moves back to its initial position, and the energy storage element 30 enters the energy dissipation state. During the tripping process of the tripping control system, the second end 32 of the energy storage element 30 is driven by the drive assembly 50 to move along the second direction from its initial position (i.e., the other side of the first limit arm 212), and the energy storage element 30 is stretched and enters the energy storage state; when the driven member 20 and the fixed member 10A unlock each other, the second end 32 of the energy storage element 30 moves back to its initial position, and the energy storage element 30 enters the energy release state.

[0100] like Figure 8 As shown, the elastic breaking auxiliary element 40 has a fixed end 41, a free end 42, and a second elastic body 43 extending from the fixed end 41. The fixed end 41 of the elastic breaking auxiliary element 40 is engaged with the first limiting structure 122 of the first limiting seat 12 of the fixing member 10A, and the free end 42 is disposed on one side of the second limiting arm 213 of the second limiting seat 21. The fixed end 41 includes a turning portion 411 extending upward from the second elastic body 43 and a first hook-back portion 412 extending bently from the turning portion 411. The fixed end 41 and the second elastic body 43 form a first hook-back groove 413, as shown. Figure 8 As shown. The opening of the first hook-back groove 413 of the fixed end 41 of the elastic breaking auxiliary element 40 faces the first limiting structure 122. The free end 42 includes an inwardly bent portion 421 that bends inward from the second elastic body 43 and a second hook-back portion 422 that extends bently from the inwardly bent portion 421. The free end 42 and the second elastic body 43 form the second hook-back groove 423, as shown. Figure 8 As shown.

[0101] The first limiting structure 122 has a recessed groove 1221 extending inward from one side. The opening direction of the groove 1221 is consistent with the second direction and opposite to the opening direction of the first hook-back groove 413, to prevent the fixed end 41 of the elastic breaking auxiliary element 40 from slipping off. The opening direction of the first hook-back groove 413 is such that its turning portion 411 points to the end of its first hook-back portion 412, and the opening direction of the groove 1221 is such that its recessed portion points to its outer edge.

[0102] The second limiting arm 213 has a recessed groove 2131 on one side, the opening direction of which is consistent with the first direction and opposite to the opening direction of the second hook-back groove 423, to prevent the movable end 42 of the elastic breaking auxiliary element 40 from slipping off. The opening direction of the second hook-back groove 423 is that its inward fold 421 points to the end of its second hook-back portion 422, and the opening direction of the groove 2131 is that its recessed portion points to its outer edge.

[0103] During the stretching process of the elastic breaking auxiliary element 40, the elastic breaking auxiliary element 40 is in an energy storage state. During the return of the elastic breaking auxiliary element 40 from the stretched state to the initial state, the elastic breaking auxiliary element 40 is in an energy dissipation state. In this example, during the closing control process of the breaking control system, when the driven member 20 and the fixed member 10A are locked together, the free end 42 of the elastic breaking auxiliary element 40 is driven by the driving assembly 50 to move along the first direction from its initial position (i.e., one side of the first limit arm), and the elastic breaking auxiliary element 40 is stretched and enters the energy storage state. During the opening process of the breaking control system, the free end 42 of the elastic breaking auxiliary element 40 moves back to its initial position, and the elastic breaking auxiliary element 40 enters the energy dissipation state.

[0104] like Figure 4 As shown, the second limiting seat 21 has a locking mounting position P0, and the locking structure 22 is fixed to the locking mounting position P0. The locking structure 22 includes a first cantilever 221 extending from the locking mounting position P0 along a first extending direction and a second cantilever 222 extending along a second extending direction.

[0105] In this example, the locking mounting position P0 is formed on the first limiting arm 212. Correspondingly, the locking structure 22 is fixed to the first limiting arm 212 of the second limiting seat 21. The locking structure 22 can be fixed to the inner surface of the first limiting arm 212 or to the outer surface of the first limiting arm 212; the fixing method can be various forms such as screw connection, riveting, welding, etc. Figure 6 As shown, the locking structure 22 includes a fixing portion 223, a first cantilever 221 extending from one side of the fixing portion 2223 along a first extending direction, and a second cantilever 222 extending from the other side of the fixing portion 223 along a second extending direction. The fixing portion 223 of the locking structure 22 corresponds to the first limiting arm 212. The fixing portion 223 is fixed and corresponds to the first limiting arm 212. Accordingly, the first cantilever 221 and the second cantilever 222 of the locking structure are located on both sides of the first limiting arm 212. The first cantilever 221 extends from one side adjacent to the first limiting arm 212 along the first extending direction toward the side of the first limiting arm 212, and the second cantilever 222 extends from the other side adjacent to the first limiting arm 212 along the second extending direction toward the side of the first limiting arm 212.

[0106] The first extension direction of the first cantilever 221 and the rotation direction of the drive component 50 during the closing control process of the disconnection control system are opposite to each other, i.e., the first direction is opposite to each other. The second extension direction of the second cantilever 222 and the second direction of the drive component 50 during the opening control process of the disconnection control system are opposite to each other. The angle between the first extension direction and the first direction is greater than 90 degrees and less than or equal to 180 degrees, and the angle between the second extension direction and the second direction is greater than 90 degrees and less than or equal to 180 degrees, so that the locking structure 22 of the disconnection control system can be unlocked under tensile force, which can reduce the risk of yield fatigue, plastic deformation and fracture caused by bending deformation of the locking structure 22 under stress.

[0107] The first cantilever 221 includes a first locking groove 201 and a first locking surface 224 located at the first locking groove 201. The second cantilever 222 includes a second locking groove 202 and a second locking surface 225 located at the second locking groove 202. Both the first locking groove 201 and the second locking groove 202 are through grooves, that is, the first locking groove 201 extends through the inner and outer surfaces of the first cantilever 212, and the second locking groove 202 extends through the inner and outer surfaces of the second cantilever 222. The first locking surface 224 extends outward from one end of the first locking groove 201, and the second locking surface 225 extends outward from one end of the second locking groove 202. The first locking surface 224 is located at the end of the first locking groove 201 away from the first limiting arm 212, and the second locking surface 225 is located at the end of the second locking groove 202 away from the first limiting arm 212.

[0108] The first cantilever 221 and the second cantilever 222 can be formed in a straight line or a curve, forming an obtuse angle with the fixing surface of the first limiting arm 212. The fixing surface of the first limiting arm 212 is the surface of the first limiting arm 212 used to fixably install the locking structure 22. The shape of the first locking groove 201 and the second locking groove 202 can be square or other shapes, such as an oblong shape. The first locking groove 201 and the second locking groove 202 can be closed-loop grooves or open-loop grooves.

[0109] The end portion 13 of the first lock head, i.e., the first bent portion 132 of the first lock head 13, is adapted to extend into the first lock groove 201 and is locked in the first lock groove 201 under certain conditions. The end portion of the first lock head 13 has a first side 1301 and a second side 1302, the first side 1301 protruding relative to the second side 1302 in a radial direction R set by the disconnection control system. The end portion of the second lock head 14, i.e., the second bent portion 142 of the second lock head 14, is adapted to extend into the second lock groove 202 and is locked in the second lock groove 202 under certain conditions. The end portion of the second lock head has a third side 1401 and a fourth side 1402, the third side 1401 protruding relative to the fourth side 1402 in a radial direction R set by the disconnection control system.

[0110] In this example, the first side 1301 of the end portion of the first lock head 13 is located counterclockwise from the second side 1302, opposite to the first direction of the drive assembly 50 during the closing control process of the disconnection control system. This ensures that when the disconnection control system is in its initial state, the locking member formed by the locking structure 22, the first lock head 13, and the second lock head 14 is in a first locked state. The first side 1301 of the end portion of the first lock head 13 protrudes from the end of the first lock groove 201 away from the first limiting arm 212 in the radial direction R set by the disconnection control system. The first side of the end portion of the first lock head 13 abuts against the first locking surface 223, and the locking structure 22 locks the first lock head 13. The locking member is switched to the first unlocked state until the first cantilever 221 of the locking structure 22 unlocks from the first lock head 13 under external force, allowing the driven member 20 to rotate along the first direction. When the locking member is switched to the second unlocked state, the driven member 20 rotates along the second direction and passes through the first lock head 13 in the first lock groove 201. The second side 1302 of the end portion of the first lock head 13 does not protrude from the first lock groove 201, and the first lock groove 201 can pass over the first lock head 13, allowing the driven member 20 to continue rotating in the second direction. Until the energy storage element 30 and the elastic breaking auxiliary element 40 complete the energy storage and release, and / or the protrusion 2112 of the second limiting seat 21 of the driven member 20 abuts against the first lock head 13 of the first limiting seat 12, the driven member 20 moves along the first direction, and when the first locking surface 224 of the first lock groove 201 passes through the first lock head 13, since the first side 1301 of the first lock head 13 protrudes from the first lock groove 201, the locking structure 22 locks with the first lock head 13, and the locking member is switched to the first unlocked state.

[0111] The third side 1401 of the end portion of the second lock head 14 is located in the clockwise direction of the fourth side 1402, opposite to the second direction of the drive assembly 50 during the closing control process of the disconnection control system, so that when the locking member switches to the first unlocking state, the driven member 20 rotates in the first direction, the fourth side 1402 of the end portion of the second lock head 14 does not protrude from the second lock groove 202, the second lock groove 202 can pass over the second lock head 14, so that the driven member 20 continues to move in the first direction. Until the energy storage element 30 completes energy release, and / or the protrusion 2112 of the second limiting seat 21 of the driven member 20 abuts against the second locking head 14 of the first limiting seat 12, the driven member 20 moves along the second direction, and when the second locking surface 225 of the second locking groove 202 passes the second locking head 14, since the third side 1401 of the second locking head 14 protrudes from the end of the second locking groove 202 away from the first limiting arm 212 in the radial direction R set by the disconnection control system, the third side of the end portion of the second locking head 14 abuts against the second locking surface 225, the locking structure 22 locks the second locking head 14, and the locking member is switched to the second locking state. Until the second cantilever 222 of the locking structure 22 unlocks from the second locking head 14 under the action of external force, the locking member is switched to the second unlocking state, allowing the driven member 20 to rotate along the second direction.

[0112] Furthermore, in this example, the disconnection control system can also disengage the locking structure 22 from the first lock head 13 or the second lock head 14 by providing a force deviating from its extension direction, thereby achieving rapid unlocking while preventing compression in the extension direction. Specifically, in this example, the driving component 50 provides a force deviating from its extension direction to the locking structure 22.

[0113] In this example, such as Figure 9As shown, the drive assembly 50 includes a drive disk 51 movably mounted to the driven member 20 and a second central rotating shaft 52 confined within the drive disk 51. In this application, the central axis of the first central rotating shaft 23 coincides with the central axis of the second central rotating shaft 52 and the rotation axis L of the disconnection control system. During the operation of the disconnection control system, the drive disk 51 can be driven to rotate by driving the second central rotating shaft 52. The drive disk 51 includes a disk body 511 and at least one actuating part connected to the disk body 511. The disk body 511 has a drive hole 501 located in its middle, which penetrates the opposing upper and lower surfaces of the disk body 511. The second central rotating shaft 52 is engaged with the drive hole 501 and passes through the drive hole 501, extending into the hollow structure of the first central shaft and the hollow structure of the bushing 24, thereby drivingly connecting the drive assembly 50 to the driven member 20.

[0114] In this example, the drive assembly 50 drives the free end 42 of the elastic disconnection auxiliary element 40 via the actuating part, and / or one of the first end 31 and the second end 32 of the energy storage element 30 to achieve closing control and opening control. In this example, the free end 42 of the elastic disconnection auxiliary element 40 has a different starting position than the first end 31 or the second end 32 of the energy storage element 30. Accordingly, the drive disk 51 is configured with at least two actuating parts, namely, a first actuating part 515 and a second actuating part 516 connected to the disk body 511, such as... Figure 10 As shown. The first actuating part 515 is operably disposed at at least one end of the energy storage element 30. In this example, the second actuating part 516 is operably disposed at the free end 42 of the elastic breaking auxiliary element 40.

[0115] like Figure 11As shown, the first actuating part 515 includes a first actuating arm 512 extending downward from the disk body 511, and the second actuating part 516 includes a second actuating arm 513 and a third actuating arm 514 extending downward from the disk body 511. The first actuating arm 512 corresponds to the first limiting arm 212 of the second limiting seat 21, and the first actuating arm 512 is located between the first end 31 and the second end 32 of the energy storage element 30. The free end 42 of the elastic breaking auxiliary element 40 is located on one side of the third actuating arm 514, so that when the drive disk 51 is driven, the actuating part can drive the free end 42 of the elastic breaking auxiliary element 40 and / or one end of the energy storage element 30 to realize the energy storage of the elastic breaking auxiliary element 40 and / or the energy storage element 30. Figure 12 As shown, the free end 42 of the elastic breaking auxiliary element 40 can also be located on one side of the second actuator arm 512 and driven to move by the second actuator arm 512.

[0116] The first actuating arm 512 has an inwardly recessed first drive groove 5121 on one side for holding the first end 31 of the energy storage element 30, and a second drive groove 5122 on the other side for holding the second end 32 of the energy storage element 30 to prevent the energy storage element 30 from slipping off. The second actuating arm 513 has an inwardly recessed groove 5133 from one side adjacent to the free end 42 of the elastic breaking auxiliary element 40. The opening direction of the groove 5133 is consistent with the first direction, and the opening direction of the groove 5133 is from its recessed part to its outer edge to prevent the elastic breaking auxiliary element 40 from slipping off the second actuating arm 513 when the free end 42 of the elastic breaking auxiliary element 40 is driven.

[0117] The first actuator 512 may be located inside the first limiting arm 212 or outside the first limiting arm 212, and is not limited thereto by this application.

[0118] The lower end of the second actuator arm 513 is used to limit the angle at which the drive disk 51 is rotated along the first direction. The first locking head 13 is located on the movement path of the lower end of the second actuator arm 513. During the process of the drive disk 51 being driven to rotate along the first direction, after the drive disk 51 has rotated a certain angle, one side of the lower end of the second actuator arm 513 abuts against the first locking head 13, preventing the drive disk 51 from continuing to rotate along the first direction. Alternatively, the outer periphery of the first limiting seat 12 at the location of the first locking head 13 can be flush with or protrude from the second actuator arm 513 in the radial direction R of the disconnection control system to limit the angle at which the drive disk 51 is rotated along the first direction.

[0119] The lower end of the third actuator arm 514 is used to limit the angle at which the drive disk 51 is rotated along the first direction. The second lock head 14 is located on the movement path of the lower end of the third actuator arm 514. During the process of the drive disk 51 being driven to rotate along the second direction, after the drive disk 51 has rotated a certain angle, one side of the lower end of the third actuator arm 514 abuts against the second lock head 14, preventing the drive disk 51 from continuing to rotate along the second direction. Alternatively, the outer periphery of the first limiting seat 12 at the location of the second lock head 14 can be flush with or protrude from the third actuator arm 514 in the radial direction R of the disconnection control system to limit the angle at which the drive disk 51 is rotated along the second direction.

[0120] The first cantilever 221 includes a first arm body 2211 and a first side end 2212 extending outward from the first arm body 2211 in the radial direction R of the disconnection control system. The second cantilever 222 includes a second arm body 2221 and a second side end 2222 extending outward from the second arm body 2221 in the radial direction R of the disconnection control system. The first side end 2212 can cooperate with the second actuating arm 513 to unlock the locking structure 22 from the first lock head 13, and the second side end 2222 can cooperate with the third actuating arm 514 to unlock the locking structure 22 from the second lock head 14.

[0121] The second actuator arm 513 includes a first actuator body 5131 and a first unlocking portion 5132 extending laterally from one side of the first actuator body 5131. The third actuator arm 514 includes a second actuator body 5141 and a second unlocking portion 5142 extending laterally from one side of the second actuator body 5141.

[0122] The first unlocking part 5132 has a first connecting end that connects to the first actuating body 5131. The first connecting end is located inside the movement path of the end of the first cantilever 221. That is, the connection between the first unlocking part 5132 and the first actuating body 5131 is located inside the movement path of the end of the first cantilever 221, so that when the drive disk 51 is rotated in the first direction until its first unlocking part 5132 reaches the first cantilever 221 of the locking structure 22, the first unlocking part 5132 abuts against the inner surface of the first side end 2212 of the first cantilever 221 of the locking structure 22.

[0123] The closer the first side end 2212 of the first cantilever 221 is to the first arm body 2211, the smaller the radial distance between it and the center O of the disconnection control system. That is, the radial distance between the first side end and the center O of the disconnection control system decreases along the direction closer to the first arm body 2211.

[0124] Accordingly, the radial distance between the first connecting end of the first unlocking part 5132 and the center O of the disconnection control system is greater than the radial distance between at least a portion of the inner surface of the first side end 2212 of the first cantilever 221 and the center O of the disconnection control system. That is, the radial distance between the junction of the first unlocking part 5132 and the first actuating body 5131 and the center O of the disconnection control system is greater than the radial distance between at least a portion of the inner surface of the first side end 2212 of the first cantilever 221 and the center O of the disconnection control system. Specifically, the junction of the first unlocking part 5132 and the first actuating body 5131 protrudes radially beyond at least a portion of the inner surface of the first side end 2212 of the first cantilever 221 in the direction set by the disconnection control system. This forces the first cantilever 221 to be pushed outwards, disengaging from the first lock head 13, thus unlocking the cantilever.

[0125] The second unlocking part 5142 has a second connecting end that connects to the second actuating body 5141. The second connecting end is located inside the movement path of the end of the second cantilever 222. That is, the connection between the second unlocking part 5142 and the second actuating body 5141 is located inside the movement path of the end of the second cantilever 222, so that when the drive disk 51 is rotated in the second direction until its second unlocking part 5142 reaches the second cantilever 222 of the locking structure 22, the second unlocking part 5142 abuts against the inner surface of the second side end 2222 of the second cantilever 222 of the locking structure 22.

[0126] The closer the second side end 2222 of the second cantilever 222 is to the second arm body 2221, the smaller the radial distance between it and the center O of the disconnection control system. That is, the radial distance between the second side end and the center O of the disconnection control system decreases along the direction closer to the second arm body 2221.

[0127] Accordingly, the radial distance between the second connecting end of the second unlocking part 5142 and the center O of the disconnection control system is greater than the radial distance between at least a portion of the inner surface of the second side end 2222 of the second cantilever 222 and the center O of the disconnection control system. That is, the radial distance between the connection between the second unlocking part 5142 and the second actuating body 5141 and the center O of the disconnection control system is greater than the radial distance between at least a portion of the inner surface of the second side end 2222 of the second cantilever 222 and the center O of the disconnection control system. In other words, the connection between the second unlocking part 5142 and the second actuating body 5141 protrudes in the radial direction set by the disconnection control system beyond at least a portion of the inner surface of the second side end 2222 of the second cantilever 222. This causes the drive disc 51 to be driven to rotate in the second direction and move along the inner surface of the second side end 2222, providing a force to the second cantilever 222 that deviates from the extension direction of the second cantilever 221, forcing the second cantilever 222 to be pushed outward and disengaged from the second lock head 14, thereby unlocking the device.

[0128] Since the first side 1301 of the first lock head 13 protrudes outward relative to the first cantilever 221 in the radial direction R of the disconnection control system, that is, protrudes in the non-extending direction of the first cantilever 221 relative to the first cantilever 221, and the third side 1401 of the second lock head 14 protrudes outward relative to the second cantilever 222 in the radial direction R of the disconnection control system, that is, protrudes in the non-extending direction of the second cantilever 222 relative to the second cantilever 222, applying a force deviating from its extending direction to the first cantilever 221 can cause the locking structure 22 to quickly unlock from the first lock head 13, and applying a force deviating from its extending direction to the second cantilever 222 can cause the locking structure 22 to quickly unlock from the second lock head 14.

[0129] In other words, in this example, the locking structure 22 of the disconnection control system is subjected not only to tensile force during unlocking, effectively preventing it from yielding in its extension direction, but also to a force deviating from its extension direction. This further prevents the locking structure 22 from yielding in its extension direction while simultaneously allowing it to be quickly disengaged from the lock head, achieving rapid unlocking. This, to some extent, improves the tripping speed of the electrical switch used, thereby enhancing its disconnection capability.

[0130] It is worth mentioning that, in this example, the adjacent sides of the second actuator 513 and the third actuator 514 are spaced apart. In a modified embodiment of this application, the adjacent sides of the third actuator 514 and the second actuator 513 may be at least partially connected, such that the second actuator 513 and the third actuator 514 are combined to form an actuator.

[0131] For example, the adjacent sides of the second actuating arm 513 and the third actuating arm 514 are connected without any gap. The second actuating part 516 includes the second actuating arm 513, which includes a first actuating portion extending downward from the disk body 511 and a second actuating portion adjacent to the first actuating portion, wherein the first actuating portion corresponds to the second actuating arm 513 in this example, and the second actuating portion corresponds to the third actuating arm 514 in this example. The free end 42 of the elastic breaking assist element 40 is located on one side of the first actuating portion, which has a groove 5133 recessed inward from its side adjacent to the free end of the elastic breaking assist element 40. The opening direction of the groove 5133 is consistent with the first direction, and the opening direction of the groove 5133 is such that its recessed portion points to its outer edge to prevent the elastic breaking assist element 40 from slipping off the first actuating portion when the free end 42 of the elastic breaking assist element 40 is actuated.

[0132] For example, adjacent sides of the second actuator arm 513 and the third actuator arm 514 are connected, and a receiving hole is formed where the adjacent sides of the second actuator arm 513 and the third actuator arm 514 are not in contact with each other. This is equivalent to forming a receiving hole between the first actuating part and the second actuating part of the second actuating part 516. The free end 42 of the elastic breaking auxiliary element 40 is located on one side of the first actuating part or on one side of the second actuating part.

[0133] The first actuating part includes a first unlocking part 5132 extending laterally from one side of the first actuating body 5131. The second actuating part includes a second actuating body 5141 and a second unlocking part 5142 extending laterally from one side of the second actuating body 5141.

[0134] The closing control process and the opening control process are described in more detail below, such as... Figures 13A to 13C As shown.

[0135] During the closing control process, the drive assembly 50 is driven to move along the first direction, the first actuating arm 512 of the drive disk 51 drives the first end 31 of the energy storage element 30 to move along the first direction, and at the same time, the second actuating arm 513 of the drive disk 51 drives the free end 42 of the elastic disconnection auxiliary element 40 to move along the first direction. The energy storage element 30 and the elastic disconnection auxiliary element 40 deform and enter the energy storage state.

[0136] The energy storage element 30 generates a torque due to torsional deformation, which exerts a pulling force on the second limiting seat 21, causing the second limiting seat 21 to tend to move in the first direction. However, the first cantilever 221 of the locking structure 22 provided on the second limiting seat 21 is locked at the first position P1 of the first limiting seat 12 by the first lock head 13, so the second limiting seat 21 remains stationary. Until one side of the lower end of the second actuating arm 513 of the drive assembly 50 abuts against the first lock head 13, the first unlocking part 5132 of the second actuating arm 513 abuts against the first cantilever 221 of the locking structure 22, providing a force to the first cantilever 221 that deviates from its extension direction, pushing the first cantilever 221 outward and disengaging it from the first lock head 13, the first lock head 13 and the first cantilever 221 of the locking structure 22 are unlocked.

[0137] At this time, the free end 42 of the elastic breaking auxiliary element 40 is driven to the first position P1 by the second actuating arm 513. The second end 32 of the energy storage element 30 is held in the second limiting seat 21. Therefore, the energy storage element 30 enters the energy release state, driving the second limiting seat 21 to move along the first direction, so that the second cantilever 222 of the locking structure 22 provided on the second limiting seat 21 moves to the second position P2 of the first limiting seat 12. The second limiting seat 21 can drive the movable contact conductive component to move closer to the stationary contact conductive component. One side of the lower end of the second actuating arm 513 of the driving component 50 abuts against the first lock head 13 and cannot continue to rotate along the first direction. The fixed end 41 of the elastic breaking auxiliary element 40 is located in the first limiting seat 12. The free end 42 of the elastic breaking auxiliary element 40 is held in the first position P1 by the second actuating arm 513. Therefore, after the second limiting seat 21 is unlocked, the elastic breaking auxiliary element 40 does not release energy.

[0138] During the movement of the second limiting seat 21 along the first direction driven by the energy storage element 30, the second limiting arm 213 of the second limiting seat 21 reaches the free end 42 of the elastic breaking auxiliary element 40. After the second locking surface 225 of the second cantilever 222 of the locking structure 22 of the second limiting seat 21 passes the second lock head 14, it returns to the second lock head 14 after the energy storage element 30 completes energy release and / or the first side edge 21121 of the protrusion 2112 of the second limiting seat 21 abuts against the first lock head 13, and is then locked by the second lock head 14, so that the moving contact of the movable contact conductive component engages with the stationary contact of the stationary contact conductive component and remains in the engaged state.

[0139] After the drive component 50 is reverse-driven, that is, after it is driven to move in the second direction, the disconnection control system enters the tripping process.

[0140] During the tripping control process, the first actuating arm 512 of the drive disc 51 drives the second end 32 of the energy storage element 30 to move in the second direction. During this process, the energy storage element 30 generates a torque due to torsional deformation, which pulls on the second limiting seat 21, causing the second limiting seat 21 to tend to move in the second direction. However, the second cantilever 222 of the locking structure 22 provided on the second limiting seat 21 is locked at the second position P2 of the first limiting seat 12 by the second lock head 14, thus keeping the second limiting seat 21 stationary. During this process, the free end 42 of the elastic tripping auxiliary element 40 is held by the second limiting arm 213 of the stationary second limiting seat 21 and is also stationary.

[0141] The second end 32 of the energy storage element 30 is continuously driven to move along the second direction until one side of the lower end of the third actuating arm 514 of the drive assembly 50 abuts against the second lock head 14, and the second unlocking part 5142 of the third actuating arm 514 abuts against the second cantilever 222 of the locking structure 22, providing a force to the second cantilever 222 that deviates from its extension direction, pushing the second cantilever 222 outward and disengaging it from the second lock head 14, thereby unlocking the second lock head 14 and the second cantilever 222 of the locking structure 22. The energy storage element 30 enters the energy release state, driving the second limiting seat 21 to move along the second direction. The second limiting arm 213 of the second limiting seat 21 stops holding the elastic breaking auxiliary element 40, and the elastic breaking auxiliary element 40 also enters the energy release state. That is, the energy storage element 30 and the elastic breaking auxiliary element 40 enter the energy release state, providing the second limiting seat 21 with a driving force in the same direction. The second limiting seat 21 is subjected to the maximum torque of both the energy storage element 30 and the elastic breaking auxiliary element 40. The maximum torque of the energy storage element 30 and the maximum torque of the elastic breaking auxiliary element 40 are superimposed. Compared with the traditional breaking control structure, the force on the driven member 20 increases by a factor of two, which increases the movement speed of the second limiting seat 21. The increased speed of the conductive contact component driven by the second limiting seat 21 causes the moving contact of the conductive contact component to move rapidly away from the stationary contact, thereby accelerating the breaking speed of the electrical switch and improving its safe breaking capability. The time required for elongation and breakage during the breaking process is shortened, resulting in less damage to the electrical switch.

[0142] During the process of the energy storage element 30 and the elastic breaking auxiliary element 40 driving the second limiting seat 21 to move along the second direction, the first limiting arm 212 of the second limiting seat 21 reaches the second end 32 of the energy storage element 30. After the first locking surface 224 of the locking structure 22 of the second limiting seat 21 passes the first lock head 14, it returns to the first lock head 13 after the energy storage element 30 and the elastic breaking auxiliary element 40 complete energy release, and / or the second side edge 21122 of the protrusion 2112 of the second limiting seat 21 abuts against the second lock head 14, and is then locked by the first lock head 13, so that the moving contact of the movable contact conductive component engages with the stationary contact of the stationary contact conductive component and remains in a separated state.

[0143] It is worth mentioning that, compared to traditional electrical switches, the energy storage element 30 of this application is smaller in size under the same breaking speed requirement, and the size of the components that cooperate with the energy storage element 30, such as the locking structure 22, is also reduced accordingly. Because the energy storage element 30 of the breaking control system is smaller, the driving force required to drive the energy storage element 30 to store energy is reduced. Since the energy storage element 30 is driven by the drive assembly 50, the driving force required to drive the drive assembly 50 is also reduced. This makes operating the breaking control system more effortless, especially when operating it manually, where this advantage is even more pronounced.

[0144] Example 2 In another example of this application, such as Figure 14 As shown, the disconnection control system includes a fixing member 10A, a driven member 20A, an energy storage element 30A, an elastic disconnection auxiliary element 40A, and a drive assembly 50A. In this specific example, the fixing member 10A includes an actuating housing 11A, a cover 15A, a first limiting seat 12A, a first locking head 13A, and a second locking head 14A. The actuating housing 11A has a receiving cavity 101A. The cover 15A covers the actuating housing 11A, and the first limiting seat 12A is positioned within the first receiving cavity 101A of the actuating housing 11A. Specifically, in this example, the first limiting seat 12A is positioned within the actuating housing 11A by means of its shape. Specifically, the shape of the receiving cavity 101A of the actuating housing 11A is not the same as the shape of the first limiting seat 12A. The shape of the receiving cavity 101A of the actuating housing 11A is close to a circle, and the shape of the first limiting seat 12A is close to a square. In this way, the first limiting seat 12A is engaged with the actuating housing 11A.

[0145] The actuating housing 11A further includes a hollow shaft 114A extending through the upper and lower surfaces of the housing base plate 111A. In this example, at least a portion of the hollow shaft 114A extends upward from the upper surface of the housing base plate 111A. The first limiting seat 12A includes a first base plate 121A having a first central through hole 1202A formed in the middle, through which the hollow shaft 114A can pass, such that the first limiting seat 12A is sleeved on the hollow shaft 114A of the actuating housing 11A.

[0146] like Figure 14As shown, in this example, the first lock head 13A is located at the first position P1A of the first limiting seat 12A, and the second lock head 14A is located at the second position P2A of the first limiting seat 12A. The first lock head 13A and the second lock head 14A respectively protrude from the first base plate 121A of the first limiting seat 12A, and are used to limit the rotation angle of the driven member 20A, locking the driven member 20A at the first position P1A or the second position P2A.

[0147] Specifically, in this example, either the first lock head 13A or the second lock head 14A can also be used to define one end of the resilient breaking auxiliary element 40A. Specifically, the first lock head 13A has a first locking cavity 133A, and the second lock head 14A has a second locking cavity 143A. One end of the resilient breaking auxiliary element 40A is engaged in the second locking cavity 143A of the second lock head 14A or the first locking cavity 133A of the first lock head 13A.

[0148] In a modified embodiment of this application, the first limiting seat 12A may be integrally formed on the actuating housing 11A, and the first base plate 121A of the first limiting seat 12A may be implemented as part of the housing base plate 111A of the actuating housing 11A. Accordingly, the first locking head 13A is protruding at a first position P1A of the housing base plate 111A, and the second locking head 14A is protruding at a second position P2A of the housing base plate 111A.

[0149] The driven member 20A is rotatably mounted on the fixed member 10A. The driven member 20A includes a second limiting seat 21A, at least one locking structure 22A disposed on the second limiting seat 21A, a first central rotating shaft 23A disposed on the second limiting seat 21A, and a bushing 24A sleeved on the first central rotating shaft 23A.

[0150] The second limiting seat 21A includes a first limiting arm 212A extending upward from the second base plate 211A. The second base plate 211A has a second central through hole 2101 located in its middle. The first central rotating shaft 23A includes a chuck, a first rotating shaft portion extending downward from the chuck, and a second rotating shaft portion extending upward from the chuck. The first central rotating shaft 23A can be mounted on the second base plate 211A through the second central through hole, wherein the second rotating shaft portion can extend above the second base plate 211A through the second central through hole, and the first rotating shaft portion is limited to the lower part of the second base plate 211A. The first rotating shaft portion is rotatably connected to the fixing member 10A, passes through the first central through hole 1202A of the first limiting seat 12A, and is sleeved on the hollow shaft 114A of the actuating housing 11A. The first rotating shaft portion is adapted to be connected to the movable contact conductive assembly of an electrical switch, thereby driving the driven member 20A to move when driven. The second rotating shaft portion has a hollow structure for drivingly connecting the drive assembly 50A. The bushing 24A is fastened to the second rotating shaft portion of the first central rotating shaft 23A and has a hollow structure corresponding to the hollow structure of the second rotating shaft portion.

[0151] Specifically, in this example, the first limiting arm 212A is used not only to limit both ends of the energy storage element 30A, but also to limit one end of the elastic breaking auxiliary element 40A. The energy storage element 30A has a first end 31A, a second end 32A, and a first elastic body 33A extending between the first end 31A and the second end 32A. The energy storage element 30A is sleeved on the bushing 24A of the second limiting seat 21A, and the first end 31A and the second end 32A of the energy storage element 30A are movably disposed on the driven member 20A. When the breaking control system is in its initial state, the first end 31A and the second end 32A of the energy storage element 30A are located on either side of the first limiting arm 212A. In this example, the first limiting arm 212A has a first limiting groove 2121A on one side and a second limiting groove 2122A on the other side. The first limiting groove 2121A is used to hold the first end 31A of the energy storage element 30A, and the second limiting groove 2122A is used to hold the second end 32A of the energy storage element 30A to prevent the energy storage element 30A from slipping out. In this example, when the disconnection control system is in the initial state, the first limiting arm 212A corresponds to the first lock head 13A.

[0152] The elastic breaking auxiliary element 40A has a fixed end 41A, a free end 42A, and a second elastic body 43A extending from the fixed end 41A. The fixed end 41A of the elastic breaking auxiliary element 40A is inserted into and engaged with the first locking cavity 133A of the first locking head 13A of the fixing member 10A or the second locking cavity 143A of the second locking head 14A of the fixing member 10A. The free end 42A of the elastic breaking auxiliary element 40A is located on one side of the first limiting arm 212A. The first limiting arm 212A has a third limiting groove 2123A on the same side as the first limiting groove 2121A, which is used to hold the free end 42A of the elastic breaking auxiliary element 40A to prevent the elastic breaking auxiliary element 40A from slipping out.

[0153] The second limiting seat 21A has a locking mounting position P0A, and the locking structure 22 is fixed to the locking mounting position P0A. The locking structure 22A includes a first cantilever 221A extending from the locking mounting position P0A along a first extending direction and a second cantilever 222A extending along a second extending direction.

[0154] In this example, the locking mounting position P0A is formed on the limiting base plate 211A. Correspondingly, the locking structure 22 is fixed to the lower surface of the second base plate 211A. The fixing method may be, but is not limited to, screw connection, riveting, or welding. The locking structure 22A includes a fixing part, a first cantilever 221A extending downward from one side of the fixing part 2223, and a second cantilever 222A extending downward from the other side of the fixing part. A locking groove 224A is formed between the first cantilever 221A and the second cantilever 222A, which is adapted to the first lock head 13A and the second lock head 14A, such that the first lock head 13A engages with the locking groove 224A, thereby locking the locking structure 22A of the driven member 20A to the first position P1A of the second limit seat 21A, or locking the second lock head 14A with the locking groove 224A, thereby locking the locking structure 22A of the driven member 20A to the second position P2A of the second limit seat 21A. When the disconnection control system is in the initial state, the locking structure 22A is locked to the first lock head 13A, such as... Figure 16 As shown.

[0155] Specifically, the first cantilever 221A includes a first arm body 2211A extending downward from one side of the fixing portion and a first side end 2212A bending upward from the first arm body 2211A. The second cantilever 222A includes a second arm body 2221A extending downward from the other side of the fixing portion 332A and a second side end 2222A bending upward from the second arm body 2221A. The first side end 2212A and the second side end 2222A are opposite to each other and spaced apart, forming the locking groove 224A.

[0156] The drive assembly 50A includes a drive disk 51A movably mounted to the driven member 20A and a second central rotating shaft 52A confined within the drive disk 51A. In this application, the central axis of the first central rotating shaft 23A coincides with the central axis of the second central rotating shaft 52A and the rotation axis L of the disconnection control system. During operation of the disconnection control system, the drive disk 51A can be driven to rotate by driving the second central rotating shaft 52A. The drive disk 51A includes a disk body 511A and at least one actuating part connected to the disk body 511A. The disk body 511A has a drive hole 501A located in its central part, the drive hole 501A penetrating the opposing upper and lower surfaces of the disk body 511A. The second central rotating shaft 52A is engaged with the drive hole 501A and passes through the drive hole 501A, extending into the hollow structure of the first central shaft and the hollow structure of the bushing 24A, thereby enabling the drive assembly 50A to be tractably connected to the driven member 20A.

[0157] In this example, the drive assembly 50A drives the free end 42A of the elastic breaking auxiliary element 40A via the actuating part, and / or one of the first end 31A and the second end 32A of the energy storage element 30A to achieve closing control and opening control. In this example, the free end 42A of the elastic breaking auxiliary element 40A is close to the starting position of the first end 31A or the second end 32A of the energy storage element 30A. Correspondingly, the drive disk 51A is configured with the same actuating part, namely, the first actuating part 515A connected to the disk body 511A, such as... Figure 15 As shown. The first actuating part 515A is operably disposed between the first end 31A and the second end 32A of the energy storage element 30A, and is also operably disposed on one side of the free end 42A of the elastic breaking auxiliary element 40A.

[0158] The first actuating unit 515A includes a first actuating arm 512A extending downward from the disk body 511A, located between the first end 31A and the second end 32A of the energy storage element 30A. The free end 42A of the elastic breaking auxiliary element 40A is located on one side of the first actuating arm 512A, and the free end 42A of the elastic breaking auxiliary element 40A and the first end 31A of the energy storage element 30A are located on the same side of the first actuating arm 512A, so that when the drive disk 51A is driven, the first actuating unit 515A can drive the free end 42A of the elastic breaking auxiliary element 40A and / or one end of the energy storage element 30A to realize the energy storage of the elastic breaking auxiliary element 40A and / or the energy storage element 30A.

[0159] The first actuator arm 512A has an inwardly recessed first drive groove 5121A on one side for holding the first end 31A of the energy storage element 30A, and a second drive groove 5122A on the other side for holding the second end 32A of the energy storage element 30A. The first actuator arm 512A also has a third drive groove 5123A on the same side as the first drive groove 5121A for holding the free end 42A of the elastic breaking auxiliary element 40A to prevent the elastic breaking auxiliary element 40A from slipping off the first actuator arm 512A when the free end 42A of the elastic breaking auxiliary element 40A is driven.

[0160] The drive assembly 50A further includes an unlocking disc 53A, used to provide a driving force to the first cantilever 221A that deviates from its extension direction, or to provide a driving force to the second cantilever 222A that deviates from its extension direction, so as to reduce the deformation time of the first cantilever 221A or the second cantilever 222A, and more specifically, to reduce the compression time of the first cantilever 221A or the second cantilever 222A, so as to reduce the fatigue risk of the locking structure 22A due to being in a yielding state for a long time.

[0161] Specifically, in this example, the first unlocking disk 53A is positioned on the driving disk 51A, and the first unlocking arm 53 and the driving disk 51A are driven synchronously. The specific implementation of the first unlocking disk 53A being positioned on the driving disk 51A is not limited to this application; for example, it can be engaged, integrally formed, welded, or fused.

[0162] The first unlocking disc 53A includes an unlocking disc body 531A, a first unlocking arm 532A extending downward from the unlocking disc body 531A, and a second unlocking arm 533A. The first unlocking arm 532A includes a first lower extension 5321A extending downward from the unlocking disc body 531A and a first inner extension 5322A extending inward from the first lower extension 5321A. The second unlocking arm 533A includes a second lower extension 5331A extending downward from the unlocking disc body 531A and a second inner extension 5332A extending inward from the second lower extension 5331A.

[0163] In this example, the first cantilever 221A has a first unlocking area 2213A located on its lower surface and adjacent to the locking groove 224A, and the second cantilever 222A has a second unlocking area 2223A located on its lower surface and adjacent to the locking 224.

[0164] The axial distance between the upper surface of the first inner extension 5322A and the lower surface of the unlocking disc body 531A is less than the axial distance between the first unlocking area 2213A of the first cantilever 221A and the lower surface of the unlocking disc body 531A. This ensures that when the first unlocking arm 532A reaches the first unlocking area 2213A of the first cantilever 221A, the first unlocking area 2213A of the first cantilever 221A is lifted by an upward force, causing the first cantilever 221A to pass over the first lock head 13A, and the locking structure 22A instantly unlocks from the first lock head 13A. This reduces the compression time of the first cantilever 221A, lowers the risk of yield fatigue, and speeds up the unlocking process.

[0165] The distance between the upper surface of the second inner extension 5332A and the lower surface of the unlocking disc body 531A is less than the distance between the second unlocking area 2223A of the second cantilever 222A and the lower surface of the unlocking disc body 531A. This ensures that when the first unlocking arm 532A reaches the second unlocking area 2223A of the second cantilever 222A, the second unlocking area 2223A of the second cantilever 222A is lifted by an upward force, causing the second cantilever 222A to pass over the second lock head 14A, thus unlocking the locking structure 22A from the second lock head 14A. This reduces the compression time of the second cantilever 222A, lowers the risk of yield fatigue, and speeds up the unlocking process.

[0166] It should be understood that the disk body 511A of the drive disk 51A and the unlocking disk body 531A can be combined into one. In other words, the unlocking disk body 531A becomes part of the disk body 511A of the drive disk 51A. The drive disk 51A includes a first actuating arm 512A, a first unlocking arm 532A, and a second unlocking arm 533A extending downward from the disk body 511A of the drive disk 51A. The first actuating arm 512A, the first unlocking arm 532A, and the second unlocking arm 533A are spaced apart from each other.

[0167] The closing control process and the opening control process are described in more detail below.

[0168] When the disconnection control system is in the initial state, the drive component 50A is not driven, and the locking groove 224A of the locking structure 22A is locked with the first lock head 13A.

[0169] During the closing control process, the drive assembly 50A is driven to move along the first direction, and the first actuating arm 512A of the drive disk 51A drives the first end 31A of the energy storage element 30A to move along the first direction. At the same time, the first actuating arm 512A of the drive disk 51A drives the free end 42A of the elastic breaking auxiliary element 40A to move along the first direction. The energy storage element 30A and the elastic breaking auxiliary element 40A deform and enter the energy storage state.

[0170] The energy storage element 30A generates a torque due to torsional deformation, which pushes the second limiting seat 21A, causing the second limiting seat 21A to tend to move in the first direction. However, the locking groove 224A of the locking structure 22A provided on the second limiting seat 21A engages with the first lock head 13A. The locking structure 22A is locked by the first lock head 13A at the first position P1A of the first limiting seat 12A, so the second limiting seat 21A remains stationary. Until the first unlocking arm 532A of the drive assembly 50A reaches the first unlocking area 2213A of the first cantilever 221A, the first unlocking area 2213A of the first cantilever 221A is lifted by an upward force, and the first cantilever 221A passes the first lock head 13A, and the locking structure 22A and the first lock head 13A are instantly unlocked.

[0171] Next, the free end 42A of the elastic breaking auxiliary element 40A is driven by the first actuating arm 51 to move towards the second position P2A. At the same time, the second end 32A of the energy storage element 30A is held in place by the second limiting seat 21A. Therefore, the energy storage element 30A enters the energy release state, driving the second limiting seat 21A to move along the first direction. This causes the second cantilever 222A of the locking structure 22A provided on the second limiting seat 21A to move towards the second position P2A of the first limiting seat 12A. The second limiting seat 21A can drive the movable contact conductive component to move towards the stationary contact conductive component.

[0172] During the process of the energy storage element 30A driving the second limiting seat 21A to move along the first direction, the locking groove 224A locks with the second lock head 14A (e.g., Figure 17 As shown), the movable contact of the movable contact conductive assembly engages with the stationary contact of the stationary contact conductive assembly and remains in the engaged state. The first limiting arm 212A of the driven member 20A reaches the free end 42A of the elastic breaking auxiliary element 40A.

[0173] After the drive component 50A is reverse-driven, that is, after it is driven to move in the second direction, the disconnection control system enters the tripping process.

[0174] During the tripping control process, the first actuating arm 512A of the drive disk 51A drives the second end 32A of the energy storage element 30A to move in the second direction. During this process, the energy storage element 30A generates a torque due to torsional deformation, which pushes against the second limiting seat 21A, causing the second limiting seat 21A to tend to move in the second direction. However, the locking groove 224A of the locking structure 22A located on the second limiting seat 21A engages with the second lock head 14A, and the locking structure 22A is locked by the second lock head 14A at the second position P2A of the first limiting seat 12A. Therefore, the second limiting seat 21A remains stationary. During this process, the free end 42A of the elastic tripping auxiliary element 40A is held by the first limiting arm 212A of the stationary second limiting seat 21A and is also stationary.

[0175] The second end 32A of the energy storage element 30A is continuously driven to move along the second direction until the second unlocking arm 533A of the drive assembly 50A reaches the second unlocking area 2223A of the second cantilever 222A. The second unlocking area 2223A of the second cantilever 222A is lifted by an upward force, and the second cantilever 221 passes over the second lock head 13. The locking structure 22A and the second lock head 13 are instantly unlocked. The energy storage element 30A enters the energy release state, driving the second limiting seat 21A to move along the second direction. The first limiting arm 212A of the second limiting seat 21A stops holding the elastic breaking auxiliary element 40A, and the elastic breaking auxiliary element 40A also enters the energy release state. That is, the energy storage element 30A and the elastic breaking auxiliary element 40A enter the energy release state, providing the second limiting seat 21A with a driving force in the same direction. The second limiting seat 21A is subjected to the maximum torque of both the energy storage element 30A and the elastic breaking auxiliary element 40A. The combined effect of the maximum torque of the energy storage element 30A and the maximum torque of the elastic breaking auxiliary element 40A results in a force that is several times greater than that of the traditional breaking control structure, thus increasing the movement speed of the second limiting seat 21A. The increased speed of the contactable conductive component driven by the second limiting seat 21A causes the moving contact of the contactable conductive component to move rapidly away from the stationary contact, thereby accelerating the breaking speed of the electrical switch and improving its safe breaking capability. The time required for elongation and breakage during the breaking process is shortened, resulting in less damage to the electrical switch.

[0176] During the process of the energy storage element 30A and the elastic breaking auxiliary element 40A driving the second limiting seat 21A to move in the second direction, the locking groove 224A locks with the first lock head 13A (e.g., Figure 16 As shown in the figure, the moving contact of the movable contact conductive component engages with the stationary contact of the stationary contact conductive component and remains in a separated state.

[0177] According to the working mechanism of the tripping control system described in this application, the tripping control and closing control are as follows: Figure 18 As shown, this application proposes a disconnection control method, which includes: S110, controlling the energy storage element 30 and the elastic disconnection auxiliary element 40 to store energy and the energy storage element 30 to release energy during the closing control process of the disconnection control system; S120, controlling the energy storage element 30 to store energy and the energy storage element 30 and the elastic disconnection auxiliary element 40 to release energy during the opening process of the disconnection control system.

[0178] It should be understood that the energy storage mode of the energy storage element 30 and the elastic disconnection auxiliary element 40 during the closing control process can be consistent with their energy storage mode during the opening control process, and the energy release mode of the energy storage element 30 and the elastic disconnection auxiliary element 40 during the closing control process can also be consistent with their energy release mode during the opening process. For example, the energy storage element 30 and the elastic disconnection auxiliary element 40 store energy together during the closing control process and also store energy together during the opening control process, and the energy stored during the closing control process is the same as the energy stored during the opening control process; the energy storage element 30 and the elastic disconnection auxiliary element 40 release energy together during the opening control process and also store energy together during the opening control process, and the energy released during the closing control process is the same as the energy released during the opening control process. Accordingly, while using the elastic disconnection auxiliary element 40 to increase the opening speed, the closing speed is also increased.

[0179] Accordingly, in a specific example of this application, the fixing member 10 is provided with a first lock head 13 and a second lock head 14, the energy storage element 30 has a first end 31 and a second end 32, the elastic breaking auxiliary element 40 has a third end and a fourth end, the driven member 20 includes a limiting seat and at least one locking structure 22 disposed on the limiting seat, the limiting seat includes a base plate and a limiting arm disposed on the base plate, the limiting arm can extend upward from the base plate and can also extend downward from the base plate. When the disconnection control system is in the tripping control state and the drive assembly 50 is not driven, at least one locking structure 22 of the driven member 20 and the first lock head 13 of the fixed member 10 are locked together, the driven member 20 is locked at the first lock head 13, the first end 31 and the second end 32 of the energy storage element 30 are located on both sides of the limiting arm, and the third end and the fourth end of the elastic disconnection auxiliary element 40 are located on both sides of the limiting arm. The third end of the elastic disconnection auxiliary element 40 corresponds to the first end 31 of the energy storage element 30, and the fourth end of the elastic disconnection auxiliary element 40 corresponds to the second end 32 of the energy storage element 30. The number of elastic disconnection auxiliary elements 40 can be 1, 2, 3, or more.

[0180] During the closing and opening control processes, the energy storage element 30 and the elastic disconnection auxiliary element 40 synchronously store or release energy. Specifically, during the closing control process, the second end 32 of the energy storage element 30 and the fourth end of the elastic disconnection auxiliary element 40 are held against one side of the limiting arm. The driving assembly 50 is driven to move along a first direction, causing the first end 31 of the energy storage element 30 and the third end of the elastic disconnection auxiliary element 40 to move synchronously along the first direction. In this process, firstly, the energy storage element 30 and the elastic disconnection auxiliary element 40 deform relative to their respective initial states, entering an energy storage state. The energy storage element 30 and the elastic disconnection auxiliary element 40 exert a force on the driven member 20, causing the driven member 20 to tend to move relative to the fixed member 10 along a first preset direction, wherein the first preset direction may or may not be consistent with the first direction. However, the driven member 20 is locked at the first lock head 13 and is prevented from moving along the first preset direction by the first lock head 13. Until the energy storage element 30 and the elastic breaking auxiliary element 40 exert force on the driven member 20, overcoming the resistance of the first locking head 13 to the driven member 20, the driven member 20 is unlocked from the first locking head 13. The energy storage element 30 and the elastic breaking auxiliary element 40 enter an energy-dissipating state, driving the driven member 20 to move along the first preset direction to the second locking head 14. Then, the driven member 20 drives the movable contact conductive assembly of the electrical switch to move closer to the stationary contact conductive assembly, causing the moving contact of the movable contact conductive assembly to move to the stationary contact of the stationary contact conductive assembly. Next, at least one locking structure 22 of the driven member 20 and the second locking head 14 of the fixing member 10A lock together, locking the driven member 20 at the second locking head 14, with the moving contact and the stationary contact remaining engaged.

[0181] During the tripping process, the first end 31 of the energy storage element 30 and the third end of the elastic tripping auxiliary element 40 are held on the other side of the limiting arm. The driving assembly 50 is driven to move along the second direction, causing the second end 32 of the energy storage element 30 and the fourth end of the elastic auxiliary element to move synchronously along the second direction. In this process, firstly, the energy storage element 30 and the elastic tripping auxiliary element 40 deform relative to their respective initial states, entering an energy storage state. The energy storage element 30 and the elastic tripping auxiliary element 40 exert a force on the driven member 20, causing the driven member 20 to tend to move relative to the fixed member 10 along a second preset direction. This second preset direction may or may not be the same as the second direction. However, the driven member 20 is locked at the second lock head 14, and is prevented from moving along the second preset direction by the second lock head 14. Until the energy storage element 30 and the elastic breaking auxiliary element 40 exert force on the driven member 20, overcoming the resistance of the second lock head 14 to the driven member 20, the driven member 20 is unlocked from the second lock head 14. The energy storage element 30 and the elastic breaking auxiliary element 40 enter an energy-dissipating state, driving the driven member 20 to move along the second preset direction to the first lock head 13. Then, the driven member 20 drives the movable contact conductive assembly of the electrical switch to move away from the stationary contact conductive assembly, causing the movable contact of the movable contact conductive assembly to separate from the stationary contact of the stationary contact conductive assembly. Next, at least one locking structure 22 of the driven member 20 and the first lock head 13 of the fixing member 10 lock each other, locking the driven member 20 at the first lock head 13, keeping the movable contact and the stationary contact separated from each other. During the tripping process, the energy storage element 30 and the elastic tripping auxiliary element 40 release energy together. Compared with the traditional tripping scheme where only the energy storage element 30 releases energy, this provides a greater driving force for the driven member 20 and the movable contact conductive assembly, which can increase the movement speed of the movable contact conductive assembly and thus increase the safe tripping capability of the electrical switch.

[0182] In summary, the disconnection control system based on the embodiments of this application is explained. The disconnection control system is applicable to electrical switches and can provide a large driving force to the movable contact conductive component of the electrical switch during the disconnection control process, thereby increasing the movement speed of the movable contact conductive component and thus increasing the safe disconnection capability of the electrical switch.

The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present application, such design should fall within the protection scope of the present application.
