Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment, in particular to an operating mechanism and a transfer switch. BACKGROUND

[0002] The main function of the transfer switch is to realize automatic switching of two power supplies. When the normal power supply fails, the transfer switch can quickly switch to the standby power supply to ensure uninterrupted power supply at the load end. Due to this feature, the transfer switch is widely used in power distribution networks with high requirements for power continuity, such as industry, medicine, post and telecommunications, petroleum, coal, metallurgy, rail transportation, computer center, military facilities, airport, fire protection and important civil buildings.

[0003] In the prior art, the switching time of the transfer switch between the normal power supply and the standby power supply is usually only about 7-8 milliseconds. This rapid switching process may cause the risk of short circuit between the normal power supply and the standby power supply. To solve this problem, some transfer switches are designed to reduce the switching time to more than 20 milliseconds by directly reducing the operating mechanism, so as to reduce the possibility of short circuit between the normal power supply and the standby power supply. This delayed switching method increases the isolation time between the power supplies to some extent, reducing the risk of short circuit. However, the deceleration design reduces the closing force of the transfer switch to some extent, resulting in a decrease in the reliability of the switch during closing, which increases the risk of equipment operation.

[0032] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying 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, in the case of no conflict, various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the protection scope of the present application.

[0034] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0035] 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 present 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 for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0036] 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 relatively more horizontal than “vertical”, and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0037] In the description of the present application, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, 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, or it can be the communication inside two elements. 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.

[0038] The transfer switch is used to automatically switch to the standby power supply when the normal power supply fails to ensure the continuity of the load power supply, and is widely used in the field with high reliability requirement for power supply. In the prior art, the switching time of the transfer switch is usually 7-8 milliseconds, but fast switching may cause short circuit risk. Although some transfer switches can extend the switching time to more than 20 milliseconds by decelerating the operating mechanism to reduce the short circuit risk, this design reduces the closing force, resulting in a decrease in the closing reliability of the switch and a hidden danger of unstable operation.

[0039] In view of the above problems, an aspect of an embodiment of the present application provides an operating mechanism which can be applied to a transfer switch and is mainly used to drive the moving contact 30 to switch between the first static contact and the second static contact to realize reliable conversion of two power supplies. As shown in the figure, the operating mechanism includes elastic members 11, a driving rod 12 and a driven rod 13 which are rotationally arranged on a rack 20. A sliding groove 13a is formed in the driven rod 13, one end of the driving rod 12 is rotationally connected to the elastic member 11, and the other end of the driving rod 12 is slidingly connected to the sliding groove 13a, so that the elastic member 11 forms a driving cooperation relationship with the driven rod 13 through the driving rod 12, and the driven rod 13 is also linked with the moving contact 30 to realize switching driving. Figures 1 to 5

[0040] Specifically, the elastic member 11 passes through three key positions in sequence along its rotation path, i.e. a first position, a second position and a third position. When switching the power supply, for example, switching the moving contact 30 from closing with the first static contact to closing with the second static contact, as shown in the figure, the elastic member 11 is located at the first position. When the elastic member 11 is driven to rotate from the first position to the second position, energy is stored in the process. As shown in the figure, when the elastic member 11 is located at the second position, it is at the maximum deformation position. As shown in the figure, when the elastic member 11 passes through the second position, the elastic member 11 releases the stored energy, so that it continues to rotate in the same direction to the third position. In this process, the elastic member 11 drives the driven rod 13 to rotate through the driving rod 12, and the driven rod 13 drives the moving contact 30 to switch to closing with the second static contact, realizing smooth transition between the two power supplies. Figure 1 Figure 2 Figure 3 ​​​​

[0041] This structural design can realize accurate adjustment of the output torque of the elastic member 11 through the combination of the driving rod 12 and the driven rod 13. Moreover, the design of the sliding groove 13a enables the connection point of the driving rod 12 and the driven rod 13 to move within the sliding groove 13a, and the distance between the connection point of the driving rod 12 and the driven rod 13 and the rotation center of the driven rod 13 also changes accordingly, resulting in a change in the transmission ratio, effectively prolonging the switching time and reducing the risk of short circuit that may occur during the switching process. In addition, through the sliding connection design of the driving rod 12 within the sliding groove 13a, the output angle of the elastic member 11 is adjusted, which can improve the flexibility and reliability during the switching process, so that the operating mechanism can provide more accurate angle control and stable torque output when coping with different application requirements.

[0042] Overall, this operating mechanism can realize reasonable switching deceleration when switching the power supply through the linkage of the elastic member 11, the driving rod 12 and the driven rod 13, effectively improve the closing reliability during the switching process, and meet the high requirements of the change-over switch for safety and stability in different application scenarios.

[0043] It should be noted that in addition to the driving rod 12 and the driven rod 13, other alternative solutions can also be used for the transmission structure to adapt to different application requirements. For example, the transmission structure can use a gear set to realize energy transmission and distribution through the meshing gear set. This structure can realize stable and accurate transmission, has high working reliability, and is suitable for various working environments. In addition, a belt or chain transmission method can also be used to transmit energy from the elastic member 11 to the movable contact 30. This structure helps to reduce noise during operation and can adapt to more complex installation space requirements. By selecting different transmission structures according to specific requirements, the operating mechanism can further optimize the switching performance, improve the durability and reliability of the system, and thus realize higher application flexibility and technical adaptability.

[0044] Optionally, a first abutting portion with a first groove is arranged at one end of the driving rod 12 close to the elastic member 11, and the first groove has opposite first and second side walls for limiting the movement range of the driving end of the elastic member 11. The connecting end of the elastic member 11 is hinged to the rack 20 to form a stable movement fulcrum, so that the elastic member 11 can rotate around the fulcrum. The driving end of the elastic member 11 is located between the first and second side walls, and the driving end of the elastic member 11 is arranged close to the first side wall.

[0045] When the elastic member 11 is in the initial first position, it has zero deformation, i.e. in an uncompressed state. During the rotation of the elastic member 11 from the first position to the second position, the elastic member 11 is gradually rotated towards the second side wall direction and deformed due to the external force, thereby achieving energy storage. The elastic deformation process in this stage not only stabilizes the transmission of movement, but also provides reserve energy for subsequent operations. It should be understood that during this process, the driving rod 12 remains stationary.

[0046] When the elastic member 11 reaches the second position, the energy storage process of the elastic member 11 is completed. At this time, the driving end of the elastic member 11 is in contact with the second side wall, preparing for the next stage of power transmission. In the subsequent movement stage, the elastic member 11 can release the stored energy to the driving rod 12 through contact with the second side wall, so that the driving rod 12 rotates and drives the movable contact 30 to rotate for state switching.

[0047] In summary, the combined design of the first groove, the elastic member 11 and the driving rod 12 can achieve the control of the deformation and energy storage of the elastic member 11 and the release of the energy. The two side walls of the first groove can provide effective restriction and guidance, making the energy storage and energy release of the elastic member 11 more controllable, thereby providing stable and continuous power support during the movement of the driving rod 12.

[0048] Optionally, as shown in Figures 1 to 4 the operating mechanism further includes a first rod member 14. The connecting end of the elastic member 11 is hinged to the rack 20, forming a stable fulcrum to ensure the stability and support force of the elastic member 11 during movement. At the same time, the driving end of the elastic member 11 is hinged to the connecting end of the first rod member 14, so that the first rod member 14 can rotate with the movement of the elastic member 11, thereby achieving force transmission. The driving end of the first rod member 14 is hinged to the driving rod 12, so that it can rotate flexibly under the action of the elastic member 11. The end of the driving rod 12 close to the elastic member 11 is provided with a second abutting portion 121 having a second groove 121a, and the second groove 121a has opposite third and fourth side walls 1211 and 1212. The driving end of the first rod member 14 is located between the third and fourth side walls 1211 and 1212, and the driving end of the first rod member 14 is arranged close to the third side wall 1211.

[0049] When the elastic member 11 rotates from the initial first position to the second position, the first rod member 14 gradually rotates towards the fourth side wall 1212 direction with the movement of the elastic member 11. In this process, the first rod member 14 gradually applies pressure to the elastic member 11, forcing the elastic member 11 to gradually deform and store energy. Through the interaction between the first rod member 14 and the elastic member 11, the energy storage process of the elastic member 11 proceeds smoothly, and as the deformation deepens, a large amount of elastic potential energy is gradually accumulated in the system.

[0050] When the elastic member 11 reaches the second position, the deformation energy storage process is completed. At this time, the driving end of the first lever 14 is in contact with the fourth side wall 1212 in the groove, entering a new force stage, providing a stable fulcrum and reliable power transmission for the subsequent energy release and driving. This ingenious design can effectively utilize the interaction between the elastic member 11 and the first lever 14 to achieve stable energy storage and precise power output, providing a solid guarantee for the smooth operation of the entire operating mechanism.

[0051] Optionally, the hinge point of the first lever 14 and the driven lever 12 coincides with the rotation center of the driven lever 12, to ensure that the force transmission path is clear and effective during driving, avoiding structural deviation or power loss caused by excessive torque or displacement.

[0052] Specifically, this structure configuration of coinciding hinge point and rotation center can effectively reduce unnecessary motion resistance and structural friction during actual operation, ensuring that the power transmission from the first lever 14 to the driven lever 12 maintains high efficiency. This configuration can achieve efficient torque transmission, enabling the driven lever 12 to rotate more smoothly under the action of the first lever 14. In addition, due to the coincidence of the rotation center and the hinge point position, the driven lever 12 can maintain a more accurate motion trajectory in each operating stage, thereby improving the motion accuracy of the entire operating mechanism.

[0053] Optionally, the sliding groove 13a is a rectangular groove extending along the length direction of the driven lever 13, or the sliding groove 13a is an arc-shaped groove with the same rotation arc as the driven lever 12.

[0054] As shown in Figure 5 When the sliding groove 13a is designed as a rectangular groove extending along the length direction of the driven lever 13, the driven lever 12 is slidingly hinged in the sliding groove 13a, and when the driven lever 12 rotates, it will drive the driven lever 13 to rotate in the opposite direction. During this process, the connection point between the driven lever 12 and the driven lever 13 moves within the sliding groove 13a, and the distance between the connection point of the driven lever 12 and the driven lever 13 and the rotation center of the driven lever 13 also changes, causing the transmission ratio to change and prolonging the conversion time. In addition, through this structure, the rotation torque of the driven lever 12 can be efficiently transmitted to the driven lever 13, ensuring that the driven lever 13 can quickly respond to the action of the driven lever 12 to complete the switching operation of the movable contact 30 connected thereto, with high power transmission efficiency.

[0055] When the sliding groove 13a is processed into an arc-shaped groove matching the rotating arc of the driving rod 12. The design of this arc-shaped groove structure allows the driving rod 12 to slide between one end to the other end of the arc-shaped groove without immediately driving the action of the driven rod 13, forming an idle stroke. The design of this idle stroke can effectively delay the switching speed and reduce the risk of short circuit. When the driving rod 12 rotates to abut the end of the arc-shaped groove, the driving rod 12 will only push the driven rod 13 to rotate in the same direction, thereby driving the moving contact 30 to switch to another power supply. Through reasonable sliding groove 13a shape, the operating mechanism can provide flexible selection under different switching requirements.

[0056] Optionally, the operating mechanism further comprises an output gear 15 for transmitting the movement of the driven rod 13 to the moving contact 30 to realize the switching action of the moving contact 30. Specifically, the driven rod 13 and the output gear 15 are drivingly connected, and the output gear 15 and the moving contact 30 are drivingly connected, so that the rotation of the driven rod 13 can directly drive the output gear 15, thereby further controlling the movement of the moving contact 30.

[0057] In order to further optimize the safety and structural stability of the system, a partition plate 17 is designed between the driven rod 13 and the output gear 15 to separate the moving contact 30 and the operating mechanism in different spaces, effectively avoiding the interference of the complex structure of the operating mechanism on the moving contact 30, and reducing the possibility of foreign matter entering the working area of the moving contact 30. Through the physical isolation of the partition plate 17, the working environment of the moving contact 30 is independent and cleaner, reducing the risk of poor contact, short circuit or misoperation caused by environmental factors or mechanism interference. In addition, the arrangement of the partition plate 17 can also improve the internal structural layout of the switch, so that each component can work more orderly in its own independent space.

[0058] Optionally, as shown in Figure 6 The operating mechanism further comprises an adapter gear 16 engaged with the output gear 15, and the driven rod 13 is coaxially fixedly connected with the adapter gear 16, and the driven rod 13 and the output gear 15 form a driving connection relationship, so that the rotation of the driven rod 13 can be smoothly transmitted to the adapter gear 16, thereby driving the output gear 15 to rotate. The output gear 15 is coaxially fixedly connected with the moving contact 30, so that the moving contact 30 can realize synchronous rotation under the driving of the output gear 15, ensuring the response speed and stability of the moving contact 30 during switching.

[0059] In addition, the linkage design of the adapter gear 16 and the output gear 15 can also adjust the position of the moving contact 30 to be located at the middle position of the entire switch. This design not only improves the movement flexibility of the moving contact 30, but also ensures that the moving contact 30 always maintains a stable neutral position during power switching, which helps to reduce the offset of the moving contact 30 and improve the operation reliability of the entire switch.

[0060] Optionally, the rotation axis of the output gear 15 coincides with the rotation axis of the driving rod 12. The alignment of the axes can further optimize the internal layout of the switch. The coinciding axis layout saves internal space and makes the power transmission path more concise, thereby reducing the energy loss and error accumulation that can occur during transmission.

[0061] In another aspect of the embodiments of the present application, a switch is provided, as shown in Figure 7 The switch comprises a rack 20 and a first static contact, a second static contact, a moving contact 30 and any of the above-mentioned operating mechanisms mounted on the rack 20, respectively. The operating mechanism is used to drive the moving contact 30 to switch between the first static contact and the second static contact. Since the switch uses the above-mentioned operating mechanism, it also has the same beneficial effects as the operating mechanism, which will not be described here.

[0062] Optionally, as shown in Figures 1 to 3 An arc-shaped slot with the same rotation arc as the elastic member 11 of the operating mechanism is formed in the rack 20. The driving end of the elastic member 11 is slidingly connected to the arc-shaped slot, so as to ensure that the elastic member 11 moves along a stable and limited path during movement, avoiding unnecessary deviation or instability.

[0063] In addition, the arc-shaped slot protrudes towards the side close to the elastic member 11. This structural feature is designed to provide the required space and support for the compression movement of the elastic member 11. Through the design of the arc-shaped slot, the elastic member 11 is properly limited and guided during movement along the arc-shaped slot, so that it can be gradually compressed. In this way, the elastic member 11 can deform and store elastic energy on a controlled path, preparing power reserves for subsequent operation.

[0064] The embodiments of the present application also provide a power distribution device. The operating mechanism and / or the switch described above are applied to the power distribution device. The power distribution device can be applied to intelligent scenarios, applied to intelligent use scenarios and Internet of Things industry, so as to realize intelligent scenario management.

The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
