DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. It should be noted that the various features in the embodiments of the present application can be combined with each other without conflict, and the combined embodiments are still within the protection scope of the present application.

[0043] It should be noted that similar reference numbers and letters refer to similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0044] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly placed when the product of the application is used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0046] In the description of the present application, it should also be noted that unless otherwise explicitly specified and limited, the terms "provided", "mounted", "connected", "linked" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] In the structure of the switch, the operating device as the core executive component is responsible for the on and off of the circuit, and is one of the most critical components. The device is usually composed of mechanical components and electrical contact points, and the connection and disconnection of the circuit are completed through physical operation. In addition, the tripping device will automatically trip when detecting a circuit fault, effectively preventing serious consequences such as electrical fire caused by short circuit, overload and other electrical faults. However, the existing operating and tripping devices have low automation degree, and users need to handle manually, which not only consumes time and energy, but also increases the risk of human error, reduces work efficiency and customer experience.

[0048] To solve the above problems, one aspect of the embodiments of the present application provides an operating device which can be applied in a switch. For example, Figures 1 to 13As shown, the operating device includes a first drive assembly 10, a rotating shaft 20, an energy storage assembly 30, and a locking assembly 40. The components work closely together to achieve automated switching operation.

[0049] Specifically, the first drive assembly 10 is driven and connected to the rotating shaft 20, serving as the power source for the operating device. Through commands from the control system, the first drive assembly 10 electrically drives the rotating shaft 20 to rotate, thereby causing other components within the operating device to perform corresponding operations. The energy storage assembly 30 is mounted on the rotating shaft 20, so that when the first drive assembly 10 is working, it can not only drive the moving contact to close via the rotating shaft 20, but also provide energy to the energy storage assembly 30 via the rotating shaft 20. During this process, after the rotating shaft 20 drives the moving contact to complete the closing operation, it will continue to drive the energy storage assembly 30 until its energy storage is complete and it locks with the latching assembly 40. The locking mechanism ensures that the energy of the energy storage assembly 30 will not be accidentally released under untriggered conditions, ensuring that the moving contact remains closed and preventing unexpected opening due to the release of energy from the energy storage assembly 30.

[0050] When the circuit is operating normally, the user can remotely control the first drive component 10 through the control system to reliably close or open the circuit. The entire process requires no manual intervention, achieving a high degree of automation and significantly improving operational convenience and efficiency. When a circuit fault occurs, the control system sends a tripping signal to the latching component 40, which then unlocks from the energy storage component 30. The energy storage component 30 releases its previously stored energy and transfers it to the moving contact via the rotating shaft 20, causing the moving contact to trip and disconnect the circuit, thus achieving remote tripping. This process is completed automatically through internal energy transfer and precise control, eliminating the need for manual operation and effectively reducing human error.

[0051] Overall, the entire operating device can reliably close and open the moving contact through the locking and unlocking of the energy storage component 30 and the latching component 40, combined with the rotation of the first drive component 10. It can also respond quickly to circuit faults, ensuring safe circuit switching. This not only improves the reliability of the device but also effectively avoids potential risks caused by electrical faults, comprehensively enhancing the automation level of the switch and the user experience.

[0052] Optionally, such as Figure 1 As shown, the energy storage component 30 is designed to include a bushing 31 mounted on a rotating shaft 20 and a first elastic element 32 fitted onto the bushing 31. The function of this component relies on the precise coordination between its components to achieve energy storage and release. Specifically, the rotating shaft 20 drives the bushing 31 to rotate, and the bushing 31 further locks itself with the locking assembly 40. During this process, the rotation of the rotating shaft 20 not only drives the bushing 31 but also simultaneously causes the first elastic element 32 to store energy.

[0053] The first elastic member 32 can be in the form of a torsion spring, which has the advantage of compact space. One end of the torsion spring is fixed to the upper support plate 71 inside the switch for supporting the first driving assembly 10, and the upper support plate 71 is fixed to the torsion spring through a downward protruding bent plate. The other end of the torsion spring is fixed to the upward protruding bent plate of the shaft sleeve 31. With the rotation of the rotating shaft 20, the one end of the torsion spring fixed to the upper support plate 71 remains stationary, while the other end fixed to the shaft sleeve 31 rotates with the shaft sleeve 31, causing the torsion spring to be compressed and store energy. Finally, when the shaft sleeve 31 is rotated to be locked with the lock assembly 40, the torsion spring completes the energy storage, and since the shaft sleeve 31 is locked with the lock assembly 40, the stored energy will not be accidentally released. At this time, the energy storage assembly 30 remains in a stable state, waiting for the control system to issue an opening or other operation instruction.

[0054] During the entire energy storage process, the connection relationship of each component can ensure efficient energy transmission and storage. The rotation of the rotating shaft 20 drives the shaft sleeve 31 and the torsion spring to work together, which not only ensures the energy storage effect, but also reduces the overall size of the device through compact design, improves space utilization, and thus provides higher efficiency and reliability for the switch.

[0055] Alternatively, as shown in Figure 1 The operating device further includes a closing and opening assembly 50, which includes a pawl 53, a cam disc 51 sleeved on the rotating shaft 20, and a second elastic member 52. The rotating shaft 20 is connected with the movable contact through the cam disc 51 to realize the closing and opening operation of the circuit. The second elastic member 52 can be designed as a torsion spring, which is sleeved outside the cam disc 51, one end of the torsion spring is in abutment with the rotating shaft 20, and the other end is in abutment with the cam disc 51, ensuring that the torsion spring completes energy storage and release under the cooperation of the rotating shaft 20 and the cam disc 51.

[0056] Specifically, the pawl 53 is independently installed on the lower support plate 72 of the switch and can rotate around the shaft. In order to accurately position, the first thrusting post 21 and the second thrusting post 22 are provided on the rotating shaft 20, and the connecting line between the first thrusting post 21 and the center of the rotating shaft 20 is 90° to the connecting line between the second thrusting post 22 and the center of the rotating shaft 20. The second cam disc 51 is provided with a protrusion 511, and the pawl 53 is provided with a corresponding recess structure. The pawl 53 is divided into a first pawl 53a and a second pawl 53b, which work with different thrusting posts and protrusions 511 to ensure accurate execution of each action step. Among them, the pawl 53 and the cam disc 51 can be made of high-strength metal material to improve the mechanical life of the device.

[0057] The rotating shaft 20 has an open position, a closed position, and an energy storage position sequentially distributed along the closing rotation path, corresponding to the positions of the first thrust column 21 and the second thrust column 22. The line connecting the open position and the center of the rotating shaft 20 forms a 90° angle with the line connecting the closed position and the center of the rotating shaft 20. When the rotating shaft 20 is in the open position, the groove of the first pawl 53a abuts tightly against the protrusion 511, and the groove of the second pawl 53b engages with the second thrust column 22. This positioning structure ensures the stability of the rotating shaft 20 in each operating phase, thereby ensuring the stability of the moving contact.

[0058] When the rotating shaft 20 rotates 90°, that is, from the open position to the closed position, it first drives the first elastic element 32 and the second elastic element 52 to store energy. Subsequently, as the first thrust column 21 rotates to contact the first pawl 53a, the first pawl 53a is driven to rotate around the shaft and release from contact with the protrusion 511. At this time, the second elastic element 52 releases energy and drives the moving contact to complete the closing operation through the cam disk 51. This energy release mechanism, through the compression and release of the torsion spring, ensures the smooth closing of the moving contact and avoids instability caused by manual operation.

[0059] As the rotating shaft 20 continues to rotate from the closed position to the energy storage position, the first elastic element 32 and the second elastic element 52 continue to store energy until the bushing 31 locks with the locking assembly 40. At this time, the locking mechanism between the energy storage assembly 30 and the locking assembly 40 ensures system stability, and during normal circuit operation, the energy storage assembly 30 does not affect subsequent closing and opening operations. Under the control of the first drive assembly 10, the rotating shaft 20 can rotate from the closed position back to the open position, or from the open position back to the closed position. During this time, the energy storage assembly 30 no longer participates in the energy storage process, ensuring efficient system operation. Only when a circuit fault occurs will the energy storage assembly 30 release the stored energy to drive the moving contact to complete the opening action.

[0060] This design enables a high degree of automation in the operating device, allowing it to automatically respond to circuit faults, ensuring safe circuit switching, and avoiding errors that may occur during manual operation. This multi-layered control and precise energy management significantly enhance the system's safety and reliability.

[0061] Optionally, such as Figure 1 As shown, a first reset element 54 is provided on the pawl 53 to ensure that the pawl 53 can quickly reset to its initial state after the operation is completed, thus preparing for the next closing and opening operation. Specifically, when the pawl 53 is driven to rotate and disengages from the cam disk 51, the first reset element 54 immediately takes effect, generating a tendency to push the pawl 53 back to maintain contact with the cam disk 51. This design ensures that the pawl 53 can automatically return to the appropriate position after each operation without additional manual intervention.

[0062] The first reset member 54 can be implemented in the form of an elastic element, such as a spring or a torsion spring, to reset the pawl 53 to the state of abutting against the cam disc 51 by using elastic potential energy. This technical feature ensures that the pawl 53 will not remain in the released state after completing a closing or opening operation, but will be quickly reset, facilitating the device to quickly prepare for the next closing or opening cycle, and effectively improving the response speed and operation efficiency of the system.

[0063] Optionally, as shown in Figure 1 The locking assembly 40 includes a lock 41 and a jumper 42, and the precise tripping operation and energy release are achieved through a complex linkage relationship between the parts. First, the energy storage assembly 30 completes locking with the lock 41 and the jumper 42 during the process of being driven to store energy. Specifically, the lock 41 and the jumper 42 are installed on the lower support plate 72 and have the ability to rotate around the shaft. During the rotation of the shaft sleeve 31 driven by the rotating shaft 20, the shaft sleeve 31 is first rotated to complete the secondary locking with the lock 41, ensuring the stability of energy storage. Then, the rotating shaft 20 continues to drive the shaft sleeve 31 and the lock 41 to rotate together, so that the lock 41 and the jumper 42 complete the primary locking. This double locking mechanism can not only avoid the risk of insecure locking, but also ensure the smoothness during unlocking and avoid the difficulty of unlocking.

[0064] The operating device also includes a tripper 43, which is also installed on the lower support plate 72 and is drivingly connected with the jumper 42. During the tripping operation, when the control system sends an opening signal remotely, the tripper 43 drives the jumper 42 to rotate in response to the signal, completing the primary unlocking with the lock 41. At this time, the lock 41 also starts to rotate and completes the secondary unlocking with the shaft sleeve 31. With the unlocking of the locking structure, the first elastic member 32 in the energy storage assembly 30 begins to release the stored energy, which is transmitted through the shaft sleeve 31 to drive the rotating shaft 20 to rotate. This rotating process further pushes the thrust column to impact the pawl 53, driving the pawl 53 to rotate around the shaft. When the pawl 53 rotates to the over-dead point position, the pawl 53 is disengaged from the abutment with the cam disc 51, allowing the second elastic member 52 to release energy. The energy release of the second elastic member 52 is transmitted through the cam disc 51 to drive the moving contact to rotate, thereby completing the opening operation.

[0065] It should be noted that, during the operation, when the rotating shaft 20 continues to rotate from the closing position to the energy storage position, the rotating shaft 20 continues to rotate because the cam disc 51 remains stationary. This design allows the second elastic member 52 to be further compressed during the energy storage process, thereby storing sufficient energy for subsequent operation. It is through this energy transmission mechanism that the second elastic member 52 can release energy at the appropriate time to drive the cam disc 51 to rotate, and ultimately drive the moving contact to complete the opening action.

[0066] In summary, through a multi-level locking mechanism and precise linkage between the energy storage component 30 and the trip unit 43, an automated tripping function can be achieved, reducing mechanical errors and human mistakes during operation and ensuring that the circuit can quickly and safely complete the tripping operation in case of fault or emergency.

[0067] Optionally, such as Figure 1 As shown, a second reset member 44 is provided between the latch 41 and the jump latch 42. This component ensures that the latch 41 and the jump latch 42 can be unlocked smoothly through energy storage deformation. When the latch 41 and the jump latch 42 are locked, the second reset member 44 deforms and stores energy. This process not only enhances the stability of the lock but also provides a power source for subsequent unlocking operations. The design of the second reset member 44 aims to ensure that the latch 41 and the jump latch 42 have a tendency to unlock spontaneously when unlocking is required, reducing the need for external driving.

[0068] Specifically, when latch 41 and trip latch 42 are locked, the second reset member 44 continuously applies force through the elastic force generated by deformation, ensuring that latch 41 and trip latch 42 always maintain a certain unlocking pressure. This pressure ensures that when an external unlocking condition is triggered, such as when trip unit 43 drives trip latch 42 to rotate and unlock latch 41, the energy stored in the second reset member 44 is rapidly released, pushing latch 41 to rotate quickly and unlock it from bushing 31. With the rapid unlocking of latch 41 and bushing 31, the second elastic member 52 in the system can release energy in advance, providing power for subsequent tripping operations. This early energy release not only improves the reaction speed of the entire latch assembly 40, achieving millisecond-level remote tripping, but also effectively shortens the tripping time, ensuring that the circuit can be disconnected in a timely manner under fault or abnormal conditions.

[0069] Optionally, such as Figures 2 to 13 As shown, the structural design of the first drive assembly 10 includes a first drive element 11 and a multi-stage transmission assembly 12, which is intended to effectively drive the rotating shaft 20 through the multi-stage transmission assembly 12 to realize the automated operation of the switch.

[0070] The first driving component 11 can be a motor, serving as a power source. Through linkage with the multi-stage transmission assembly 12, it transmits power to the rotating shaft 20. The multi-stage transmission assembly 12 consists of a driving gear and multiple driven gears. For example, a three-stage transmission assembly includes one driving gear and two driven gears, while a four-stage transmission assembly adds one more driven gear to further increase the output torque. The driving gear and multiple driven gears are stacked and meshed, transmitting power step by step, ultimately transmitting the power to the rotating shaft 20 via the driven gears. The motor's input end is electrically connected to the control system, ensuring that the motor can be controlled remotely via signals, while the motor's output end is connected to the driving gear, thereby achieving precise control and operation of the rotating shaft 20.

[0071] Due to the layered arrangement of the driving gear and the plurality of driven gears, the overall structure can be more compact, effectively reducing the volume of the device, and improving the transmission efficiency, making the output torque larger. In addition, the semi-modular design makes the device have good scalability and maintainability. Through this modular transmission assembly layout, different transmission requirements can be flexibly adjusted by increasing or decreasing the number of gear layers to meet the torque and power transmission requirements in different scenarios, improving the flexibility and adaptability of the device, while simplifying the assembly and maintenance process.

[0072] When the circuit fails, the trip 43 completes the unlocking of the trip 42 and makes the circuit tripped. At this time, in order to ensure that the system can respond quickly at the next fault, the trip 43 needs to be reset in time to prepare for the next tripping operation. In order to achieve this function, optionally, a second driving assembly 60 is configured in the operating device for driving the trip 43 to reset. The core part of the second driving assembly 60 is the second driving member 61 and the gear transmission assembly 62, which realize the reset action of the trip 43 through cooperative work.

[0073] Specifically, the second driving member 61 is usually a motor, and its input end is electrically connected with the control system so as to be controlled by remote signals. When the control system issues a reset instruction, the motor starts and transmits driving force through its output end connected with the gear transmission assembly 62. The gear transmission assembly 62 converts the rotary motion of the motor into the action of driving the trip 43 to reset.

[0074] Among them, as shown in Figures 2 to 7 , the gear transmission assembly 62 can be composed of a plurality of gears meshing with each other. This design can convert the rotary motion of the motor into the rotary motion of the gear, and the gear continues to rotate to press the trip 43 to reset after abutting against the trip 43. As shown in Figures 8 to 13 , the gear transmission assembly 62 can also adopt the structure that the gear meshes with the rack. The rotary motion of the motor is converted into the linear reciprocating motion of the rack by the gear transmission assembly 62, and the linear motion direction of the rack is parallel to the reset direction of the trip 43, so that the trip 43 can quickly return to the initial position by the pushing force of the rack after completing the unlocking action.

[0075] In summary, through the design of automatic reset, not only the reset efficiency of the trip 43 can be improved, but also the stability and automation level of the whole device can be improved through remote control and gear transmission technology, ensuring the quick reset and recovery of the circuit after failure, and providing reliable technical support for subsequent operation.
