Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a disconnecting switch. Background Technology

[0002] Disconnecting switches are core equipment in power systems used to achieve circuit isolation and ensure the safety of equipment maintenance. The timeliness, controllability, and safety of their opening and closing operations directly affect the stability of power system operation.

[0003] Currently, disconnect switches are typically driven by either manual or electric motors. Manual operation relies on on-site manual intervention, which is cumbersome and labor-intensive. Electric motor-driven operation is subject to limitations in motor starting, transmission mechanism response, and electrical control logic. Therefore, current drive methods are ill-suited to the rapid switching requirements of modern power systems. Summary of the Invention

[0004] This application provides a disconnecting switch that can achieve a faster response speed and better adapt to the usage requirements of power systems.

[0005] In a first aspect, this application provides a disconnecting switch, including a switch body, a frame mechanism, and a reversing mechanism. The switch body has a main shaft inside, which is rotatable to open or close the switch. The frame mechanism has an output shaft and a button structure for receiving operation commands. The surface of the button structure is located on one side of the switch body along the axis of the main shaft. The axis of the output shaft intersects the axis of the main shaft. When the button structure receives an operation command, the output shaft can output power. The reversing mechanism is disposed between the main shaft and the output shaft. When the output shaft rotates, the output shaft can drive the main shaft to rotate via the reversing mechanism.

[0006] In this application, a frame mechanism is used to drive the switch body. Within the frame mechanism, power can be released instantaneously based on operating commands, resulting in a rapid response from the output shaft. This improves the switch body's response speed, allowing the disconnecting switch to better meet the power system's requirements for rapid switching.

[0007] Optionally, the reversing mechanism includes a first crank handle, a first connecting rod, a first sliding rod, a second connecting rod, and a second crank handle. The two ends of the first connecting rod are rotatably connected to the first crank handle and the first sliding rod, respectively. The first sliding rod is slidably mounted. One end of the second connecting rod is rotatably connected to the first sliding rod, and the other end of the second connecting rod is rotatably connected to the second crank handle. The axes of relative rotation of the first connecting rod and the first sliding rod intersect the axes of relative rotation of the second connecting rod and the first sliding rod. The first crank handle is drive-connected to the output shaft, and the main shaft is drive-connected to the second crank handle.

[0008] In the above configuration, the reversing mechanism, output shaft, and main shaft can form a double four-bar linkage mechanism, which can convert the power output from the output shaft twice, thereby enabling the frame mechanism to drive the main shaft to rotate and realize the control of the switch body.

[0009] Optionally, the reversing mechanism further includes a first protrusion and a second protrusion, which are connected to the first slide rod along the sliding direction of the first slide rod. A first connecting rod is rotatably connected to the first protrusion, and a second connecting rod is rotatably connected to the second protrusion. The first protrusion protrudes from the first slide rod along the axis of relative rotation between the second connecting rod and the first slide rod, and the second protrusion protrudes from the first slide rod along the axis of relative rotation between the first connecting rod and the first slide rod.

[0010] This facilitates the connection between the first and second links and the first slide rod, reducing the possibility that the first slide rod may be too small in a certain direction, leading to inconvenience in connecting the first or second link.

[0011] Optionally, the reversing mechanism may also include a bracket with a slide rail formed inside, and the first slide rod is slidably embedded in the slide rail.

[0012] With the above settings, the bracket can guide and limit the sliding of the first slide bar, making the movement trajectory of the first slide bar stable and ensuring the reliability of the spindle's movement based on the output shaft.

[0013] Optionally, the bracket includes a base plate and limiting plates respectively disposed on both sides of the base plate, and a slide is formed between the base plate and the limiting plates.

[0014] In this way, the base plate can support the first slide rod, making the sliding of the first slide rod in the slide rail relatively smooth. The limiting plates on both sides of the base plate can limit and guide the sliding of the first slide rod 33, making the sliding of the first slide rod in the bracket precise and ensuring the reliability of the power transmission of the reversing mechanism.

[0015] Optionally, the reversing mechanism further includes a third link, and the second rocker includes a rotating disk and a connecting shaft connected to each other, with the main shaft and the rotating disk being drively connected. The other end of the second link is rotatably connected to one end of the third link, and the other end of the third link is fixed to the connecting shaft.

[0016] The above settings can better adapt to the setting of the switch body spindle, reduce the processing and assembly accuracy requirements of the frame mechanism, switch body and reversing mechanism, and reduce the possibility that after the reversing mechanism is set up, there is a deviation between the second link and the spindle, which may lead to misalignment between the second link and the spindle, making it impossible to connect to the spindle and thus unable to transmit power.

[0017] Optionally, the output shaft axis is perpendicular to the spindle axis.

[0018] In this way, the alignment reference between the switch body and the frame mechanism is clear when installing the disconnecting switch, making installation and positioning more intuitive and facilitating quick alignment during assembly, thus simplifying installation. Furthermore, it reduces the possibility of increased space occupation due to misalignment or misalignment between the disconnecting switch and the frame mechanism.

[0019] Optionally, the reversing mechanism includes a first bevel gear and a second bevel gear that mesh with each other, the first bevel gear cooperating with the output shaft and the second bevel gear cooperating with the main shaft.

[0020] In this way, the first bevel gear and the second bevel gear can convert rotation about the axis of the first bevel gear into rotation about the axis of the second bevel gear, thereby enabling the output shaft to drive the main shaft.

[0021] Optionally, there are multiple switch bodies, which are arranged adjacent to each other and connected by a main shaft drive. The frame mechanism is located on one side of the multiple switch bodies.

[0022] In this way, the frame mechanism can control multiple switch bodies through the commutation mechanism, so that multi-phase circuits can be connected or disconnected at the same time, reducing faults such as phase loss and interphase arc discharge.

[0023] Optionally, the disconnecting switch also includes an accessory, which is assembled into and electrically connected to the frame mechanism. The accessory is used to receive remote control signals, enabling the frame mechanism to control the switch body based on these signals.

[0024] In this way, remote control of the switch body can be achieved through accessories, improving the convenience of disconnecting switch operation and increasing the flexibility of controlling the disconnecting switch. Attached Figure Description

Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0038] The disconnector switch 100 provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, the disconnecting switch 100 provided in this application includes a switch body 10, a frame mechanism 20, and a reversing mechanism 30. The switch body 10 has a main shaft 11 inside, which is rotatable to open or close the switch body 10. The frame mechanism 20 has an output shaft 21 and a button structure 22 for receiving operation commands. The surface of the button structure 22 is located on one side of the switch body 10 along the axis of the main shaft 11. The axis of the output shaft 21 intersects the axis of the main shaft 11. When the button structure 22 receives an operation command, the output shaft 21 can output power. The reversing mechanism 30 is disposed between the main shaft 11 and the output shaft 21. When the output shaft 21 rotates, the output shaft 21 can drive the main shaft 11 to rotate via the reversing mechanism 30.

[0040] In this embodiment of the application, the disconnecting switch 100 includes a switch body 10 and a frame mechanism 20. The switch body 10 is the core execution component of the disconnecting switch 100 that can realize the circuit opening and closing. When the main shaft 11 of the switch body 10 rotates, the switch body 10 can switch between the closed and open states.

[0041] The frame mechanism 20 can serve as the drive mechanism in the disconnector switch 100. The frame mechanism 20 can drive the main shaft 11 of the switch body 10 to rotate through the output shaft 21, thereby controlling the switch body 10 to open or close.

[0042] The frame mechanism 20 also has a button structure 22, which is a trigger element in the frame mechanism 20. The button structure 22 can be pressed by the operator so that the frame mechanism 20 can output power through the output shaft 21.

[0043] Generally, when installing the disconnect switch 100, it is positioned so that the front faces the operator or the cabinet door of the distribution cabinet. The front of the disconnect switch 100 is the surface of the switch body 10 along the axis of the main shaft 11, which facilitates operation and maintenance.

[0044] In this application, the surface where the button structure 22 is located is also on one side of the switch body 10 along the axis of the main shaft 11. Similarly, the button structure 22 is also the front of the frame mechanism 20, allowing operators to operate or maintain the frame mechanism 20 from its front side. This configuration allows the frame mechanism 20 to be mounted upright on the front of the switch body 10, making operation more intuitive and convenient.

[0045] In the above installation method, the output shaft 21 and the main shaft 11 are set at an angle, or in other words, the axis of the output shaft 21 intersects the axis of the main shaft 11. In order for the frame mechanism 20 to drive the main shaft 11 of the switch body 10, a reversing mechanism 30 is also provided between the frame mechanism 20 and the switch body 10. The reversing mechanism 30 can rotate the power of the frame mechanism 20 to be output in a direction that matches the main shaft 11, so that the switch body 10 can open or close based on the action of the frame mechanism 20.

[0046] That is, in this application, the frame mechanism 20 drives the switch body 10 to work. In the frame mechanism 20, the frame mechanism 20 can release power instantaneously based on the operation command, so that the output shaft 21 responds quickly, thereby improving the response speed of the switch body 10 and enabling the disconnecting switch 100 to better adapt to the power system's requirements for rapid opening and closing.

[0047] It should be noted that the frame mechanism 20 has a closing spring and a opening spring inside. By relying on the closing spring and the opening spring to store energy in advance, the elastic potential energy of the corresponding spring can be released after receiving the operation command. The energy bursts instantly. Compared with the slow work done by the motor and the handle drive, the response is faster. This makes the isolating switch 100 driven by the switch body 10 in this way more suitable for the current rapidly developing power system.

[0048] The frame mechanism 20 is typically used as a drive component in a frame circuit breaker, and the specific structure of the frame mechanism 20 will not be described in detail here.

[0049] In some embodiments, such as Figures 2 to 4 As shown, the reversing mechanism 30 may include a first crank 31, a first connecting rod 32, a first sliding rod 33, a second connecting rod 34, and a second crank 35. The two ends of the first connecting rod 32 are rotatably connected to the first crank 31 and the first sliding rod 33, respectively. The first sliding rod 33 is slidably disposed. One end of the second connecting rod 34 is rotatably connected to the first sliding rod 33, and the other end of the second connecting rod 34 is rotatably connected to the second crank 35. The axes of relative rotation of the first connecting rod 32 and the first sliding rod 33 intersect the axes of relative rotation of the second connecting rod 34 and the first sliding rod 33. The first crank 31 is drive-connected to the output shaft 21, and the main shaft 11 is drive-connected to the second crank 35.

[0050] In this embodiment, the first rocker arm 31 is rotatably connected to the output shaft 21. The first rocker arm 31 can rotate under the drive of the output shaft 21, thereby driving the first connecting rod 32 to perform a compound motion. At this time, the first connecting rod 32 rotates around the connection position between the first connecting rod 32 and the first rocker arm 31 on one side, and rotates around the connection position between the first connecting rod 32 and the first sliding rod 33 on the other side. During the movement of the first connecting rod 32, the first sliding rod 33 can be driven to slide. In this part of the structure, the rotation of the output shaft 21 can be converted into the sliding of the first sliding rod 33.

[0051] The reversing mechanism 30 also includes a second connecting rod 34 and a second rocker arm 35. During the sliding of the first sliding rod 33, the first sliding rod 33 can drive the second connecting rod 34 to perform a combined motion, causing one end of the second connecting rod 34 to rotate around its connection position with the first sliding rod 33, and the other end of the second connecting rod 34 to rotate around its connection position with the second rocker arm 35. During the movement of the second connecting rod 34, it can drive the second rocker arm 35 to rotate. The second rocker arm 35 is connected to the main shaft 11, and the rotation direction of the second rocker arm 35 is the same as the rotation direction of the main shaft 11. In this part of the structure, the sliding of the first sliding rod 33 can be converted into the rotation of the second rocker arm 35 and the main shaft 11.

[0052] In the above configuration, the reversing mechanism 30, output shaft 21, and main shaft 11 can form a double four-bar linkage mechanism, which can convert the power output from output shaft 21 twice, thereby enabling frame mechanism 20 to drive main shaft 11 to rotate and realize control of switch body 10.

[0053] In this embodiment, the resulting reversing mechanism 30 has a simple structure, few parts, convenient processing and assembly, and low manufacturing cost. Furthermore, the transmission of each link in the reversing mechanism 30 is direct and has good rigidity, resulting in sensitive action response, improving the motion synchronization of the output shaft 21 and the main shaft 11, and enhancing the response speed of the switch body 10.

[0054] Furthermore, the output shaft 21 of the frame mechanism 20 typically rotates by 40° to 50° in a single operation, while the main shaft 11 of the switch body 10 typically rotates by 90° during opening and closing. Therefore, in order for the frame mechanism 20 to drive the switch body 10 to switch between opening and closing states, the commutation mechanism 30 also performs the function of variable angle transmission. In this application, the transmission ratio of the commutation mechanism 30 is between 0.44 and 0.55.

[0055] In this application, the aforementioned transmission ratio can be achieved by adjusting the effective lengths of each component in the reversing mechanism 30. Specifically, the effective length of the first rocker 31 is the distance between its rotation center and the rotation center of the position where the first connecting rod 32 connects to the first rocker 31. The effective length of the first connecting rod 32 is the distance between the rotation center of the position where the first connecting rod 32 connects to the first rocker 31 and the rotation center of the position where the first connecting rod 32 connects to the first slide rod 33. The effective lengths of the second rocker 35 and the second connecting rod 34 can be referenced above, and will not be repeated in this embodiment.

[0056] In this example, the effective lengths of the first crank 31, the first link 32, the second link 34, and the second crank 35 can be matched with the transmission ratio of the double four-bar linkage. Thus, by matching the effective lengths of each part, the rotation of the output shaft 21 can drive the main shaft 11 to rotate, enabling the switch body 10 to normally switch between opening and closing.

[0057] In this application, we will take a single rotation angle of 47° for the output shaft 21 and a rotation angle of 90° for the main shaft 11 as an example for illustration. Under this transmission relationship, the effective length of the first rocker 31 can be 46mm, the effective length of the first connecting rod 32 can be 52mm, the effective length of the second connecting rod 34 can be 27.5mm, and the effective length of the second rocker 35 can be 20.5mm.

[0058] In this application, in order for the reversing mechanism 30 to convert the rotation of the output shaft 21 in its own axial direction into the rotation in the axial direction of the main shaft 11, so as to drive the switch body 10, the axial directions of the relative rotation of the first link 32 and the first slide bar 33 intersect with the axial directions of the relative rotation of the second link 34 and the first slide bar 33.

[0059] Specifically, the axis of rotation between the first connecting rod 32 and the first slide rod 33 is in the same direction as the rotation direction of the output shaft 21, and the axis of rotation between the second connecting rod 34 and the first slide rod 33 is in the same direction as the rotation direction of the main shaft 11.

[0060] Thus, the first link 32 and the second link 34 are connected to the first slide bar 33 at different positions. In order to facilitate the connection between the first link 32 and the second link 34, the present application has also made the following settings.

[0061] like Figure 1 and Figure 4 As shown, the reversing mechanism 30 also includes a first protrusion 331 and a second protrusion 332. The first protrusion 331 and the second protrusion 332 are connected to the first slide rod 33 along the sliding direction of the first slide rod 33. The first protrusion 331 can provide a connection position for the first connecting rod 32, and the second protrusion 332 can provide a connection position for the second connecting rod 34. In this application, the first connecting rod 32 can be rotatably connected to the first protrusion 331, and the second connecting rod 34 can be rotatably connected to the second protrusion 332.

[0062] In this application, the first protrusion 331 and the second protrusion 332 are connected to the first slide bar 33 in different ways, such that the first protrusion 331 and the second protrusion 332 protrude from the first slide bar 33 in different directions.

[0063] In this application, the first protruding rod 331 protrudes from the first slide rod 33 along the axis of rotation between the second connecting rod 34 and the first slide rod 33, and the second protruding rod 332 protrudes from the first slide rod 33 along the axis of rotation between the first connecting rod 32 and the first slide rod 33. For ease of explanation, in the following description, the axis of rotation between the first connecting rod 32 and the first slide rod 33 will be referred to as the first direction, and the axis of rotation between the second connecting rod 34 and the first slide rod 33 will be referred to as the second direction.

[0064] In a specific configuration, the first protruding rod 331 and the first connecting rod 32 can be connected by the first rotating shaft, and the second protruding rod 332 and the second connecting rod 34 can be connected by the second rotating shaft.

[0065] In the above configuration, the first protrusion 331 protrudes along the second direction. This makes the first protrusion 331 larger in the second direction, which facilitates the provision of a first rotating hole extending along the first direction on the first protrusion 331. This allows the first rotating shaft to be placed in the first rotating hole, thereby connecting the first connecting rod 32 and the first sliding rod 33.

[0066] Similarly, the second protrusion 332 protrudes along the first direction. In this way, the second protrusion 332 has a larger dimension in the first direction, which makes it easier to set a second rotating hole extending along the second direction on the second protrusion 332 so that the second rotating shaft can be set in the second rotating hole to realize the connection between the second connecting rod 34 and the first sliding rod 33.

[0067] This facilitates the connection between the first link 32 and the second link 34 and the first slide bar 33, reduces the possibility that the first slide bar 33 may be too small in a certain direction, which could lead to inconvenience in connecting the first link 32 or the second link 34, and allows the rotation of the first link 32 and the second link 34 to avoid the first slide bar 33, making the movement of each part smoother.

[0068] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the reversing mechanism 30 may also include a bracket 36, in which a slide rail is formed, and the first slide rod 33 is slidably embedded in the slide rail.

[0069] Through the above configuration, the bracket 36 can guide and limit the sliding of the first slide bar 33, stabilizing its movement trajectory and ensuring the reliability of the spindle 11's movement based on the output shaft 21. This guarantees the reliability of the double four-bar linkage mechanism's movement and reduces the possibility of transmission jamming, unstable transmission ratio, and reduced response speed and accuracy of the spindle 11 due to wobbling or offset of the first slide bar 33.

[0070] In some embodiments, the bracket 36 may include a base plate 361 and limiting plates 362 respectively disposed on both sides of the base plate 361, with a slide rail formed between the base plate 361 and the limiting plates 362. Figure 3 As shown.

[0071] In this way, the base plate 361 can support the first slide rod 33, making the sliding of the first slide rod 33 in the slide rail relatively smooth. The limiting plates 362 located on both sides of the base plate 361 can limit and guide the sliding of the first slide rod 33, making the sliding of the first slide rod 33 in the bracket 36 precise and ensuring the reliability of the power transmission of the reversing mechanism 30.

[0072] The number of brackets 36 can be multiple, and the multiple brackets 36 are distributed along the sliding direction of the first slide rod 33. The multiple brackets 36 can cooperate to guide the sliding of the first slide rod 33, so that the first slide rod 33 can be limited in each position under the action of the brackets 36 during the sliding process.

[0073] In some embodiments, such as Figure 1 and Figure 4 As shown, the reversing mechanism 30 may further include a third link 37, and the second rocker arm 35 includes a rotating disk 351 and a connecting shaft 352 connected to each other. The rotating disk 351 is connected to the main shaft 11 in a transmission manner. The other end of the second link 34 is rotatably connected to one end of the third link 37, and the other end of the third link 37 is fixed to the connecting shaft 352.

[0074] That is, in this application, a third connecting rod 37 is also provided between the second rocker 35 and the second connecting rod 34 for transmission. The rotating disk 351 in the second rocker 35 is connected to the main shaft 11 and can directly drive the main shaft 11 to rotate. The connecting shaft 352 is connected to the rotating disk 351 and provides a connection position for the third connecting rod 37.

[0075] The above settings can better adapt to the setting of the main shaft 11 in the switch body 10. In actual settings, the connection position of the third link 37 on the connecting shaft 352 can be adjusted according to the position of the frame mechanism 20 and the switch body 10, reducing the processing and assembly accuracy requirements of the frame mechanism 20, the switch body 10 and the reversing mechanism 30, and reducing the possibility that after the reversing mechanism 30 is set up, there is a deviation between the second link 34 and the main shaft 11, which may cause the second link 34 to be misaligned with the main shaft 11, making it impossible to connect the main shaft 11 and thus unable to transmit power.

[0076] In some embodiments, the axis of the output shaft 21 intersects the axis of the main shaft 11. The axis of the output shaft 21 and the axis of the main shaft 11 can be configured in various ways.

[0077] Specifically, the axis of the output shaft 21 can be perpendicular to the axis of the main shaft 11. This provides a clear alignment reference between the switch body 10 and the frame mechanism 20 when installing the disconnect switch 100, making installation and positioning more intuitive and facilitating quick alignment during assembly, thus simplifying installation. Furthermore, it reduces the possibility of increased space occupation due to misalignment or offset between the disconnect switch 100 and the frame mechanism 20.

[0078] In this embodiment, the axis of the output shaft 21 is perpendicular to the axis of the main shaft 11, which facilitates the arrangement and operation of the reversing mechanism 30. For example, it can make the transmission path between the first rocker 31, the first connecting rod 32, the first slide rod 33, the second connecting rod 34, and the second rocker 35 more regular, reducing the horizontal lateral force component and making the power transmission more direct and efficient.

[0079] Of course, the axis of the output shaft 21 and the axis of the main shaft 11 may also have other angular values. For example, 75°, 80°, 86°, 92° or 95°, etc., and this embodiment does not specifically limit this.

[0080] When the angle between the axis of the output shaft 21 and the axis of the main shaft 11 is other angle values, the connection direction between the second link 34 and the first slide rod 33 can be adjusted so that the rotation direction of the second link 34 is consistent with the axis direction of the main shaft 11. In this way, the power of the output shaft 21 can be converted to drive the main shaft 11 to rotate.

[0081] In the above embodiment, the description is based on the reversing mechanism 30 as a linkage mechanism. In addition to the above configuration, the reversing mechanism 30 may also have other configurations. For example, the reversing mechanism 30 may include a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is engaged with the output shaft 21, and the second bevel gear is engaged with the main shaft 11.

[0082] In this way, the first bevel gear and the second bevel gear can convert rotation about the axis of the first bevel gear into rotation about the axis of the second bevel gear, thereby enabling the output shaft 21 to drive the main shaft 11. Under the above configuration, the power transmission of the reversing mechanism 30 is relatively stable, the movement synchronization between the output shaft 21 and the main shaft 11 is good, and the structure of the reversing mechanism 30 is also compact, improving its space utilization in the disconnector switch 100.

[0083] In some embodiments, the number of switch bodies 10 can be multiple, the multiple switch bodies 10 are arranged adjacent to each other, and the main shafts 11 of the multiple switch bodies 10 are connected by a drive, and the frame mechanism 20 is arranged on one side of the multiple switch bodies 10.

[0084] In this application, the disconnecting switch 100 is provided with multiple switch bodies 10, which can be connected to different phase lines to control the on / off state of the multi-phase circuit.

[0085] In this embodiment, the main shafts 11 of multiple switch bodies 10 are interconnected. Thus, the frame mechanism 20 can control the multiple switch bodies 10 via the commutation mechanism 30, allowing multi-phase circuits to be simultaneously connected or disconnected, reducing faults such as phase loss and inter-phase arcing. Simultaneously, this arrangement also enables electrical isolation of multi-phase circuits, ensuring maintenance safety and improving the operational reliability and electrical safety of the disconnector switch 100.

[0086] Multiple switch bodies 10 can be located on the same side as the output shaft 21, which makes the operation of the frame mechanism 20 more convenient and reduces the impact of the setting of the switch bodies 10 on the operation process of the frame mechanism 20.

[0087] In some embodiments, the disconnector switch 100 may further include an accessory, which is assembled to and electrically connected to the frame mechanism 20. The accessory is used to receive remote control signals, enabling the frame mechanism 20 to control the switch body 10 to operate based on the remote control signals.

[0088] In this embodiment, the attachment enables the frame mechanism 20 to support remote control, thus enabling remote control of the switch body 10, improving the ease of operation of the disconnect switch 100, and increasing the flexibility of controlling the disconnect switch 100.

[0089] Thus, the disconnector 100 proposed in this application has two operation modes: manual operation and remote operation, which serve as backups for each other. This allows the disconnector 100 to be adapted to a wider range of application scenarios and to better adapt to the intelligent development of power systems.

[0090] The accessory may contain a drive coil and a drive mechanism. When the accessory receives a remote control signal to control the closing of the switch body 10, the drive mechanism can operate to drive the closing spring to store energy. After the energy is stored, the drive coil will activate to unlock the internal latch of the frame mechanism 20, release the closing spring, and thus control the closing of the switch body 10.

[0091] When the accessory receives a remote control signal to open the switch body 10, the drive coil actuates to unlock the internal latch of the frame mechanism 20, releasing the opening spring and thus controlling the switch body 10 to close. The opening spring has already stored energy during the closing process.

[0092] In this embodiment, the frame mechanism 20 drives the switch body 10 to operate. The frame mechanism 20 can release power instantaneously based on an operation command, resulting in a rapid response from the output shaft 21. This improves the response speed of the switch body 10, enabling the disconnector switch 100 to better adapt to the power system's requirements for rapid switching.

[0093] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
