Description

Technical Field

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

[0002] A disconnecting switch is a widely used switching device in power systems. The core features of a disconnecting switch are that when it is in the open position, the contacts have a specified insulation distance and a clear disconnection mark, and when it is in the closed position, it can carry current under normal circuit conditions as well as current under abnormal conditions for a specified time.

[0003] Microswitches are a key auxiliary control component within disconnecting switches. Their core function is to monitor the open or closed status of the disconnecting switch, enabling status feedback, interlocking protection, and automated control to ensure the safe and stable operation of the power system. However, existing disconnecting switches suffer from low space utilization. Utility Model Content

[0004] This application provides a disconnecting switch that improves the space utilization of the disconnecting switch.

[0005] In a first aspect, this application provides a disconnecting switch. The disconnecting switch includes a housing, a drive assembly, and a micro switch assembly. The housing has an installation space. The drive assembly is movably disposed within the installation space. The micro switch assembly is disposed on one side of the drive assembly, and the micro switch assembly includes a first micro switch and a second micro switch. The drive assembly and the micro switch assembly are linked to control the first micro switch or the second micro switch to be turned on.

[0006] With the above-described solution, in this application, the microswitch group is located on one side of the drive assembly; that is, both the first and second microswitches are located on the same side of the drive assembly. Compared to the prior art where the two microswitches are respectively located on opposite sides of the drive assembly, this application utilizes only one side of the drive assembly's space, allowing the space on the other side of the drive assembly to be used for other purposes. This arrangement improves the space utilization rate of the disconnector switch.

[0007] The drive assembly allows for the independent control of either the first or second microswitch. This ensures that the first and second microswitches are positioned on the same side of the drive assembly without affecting their operation. Furthermore, controlling two microswitches with a single trigger medium reduces the need for another trigger medium, thus minimizing the possibility of reduced reliability due to assembly errors or wear of the two trigger media. This, in turn, improves the overall reliability of the disconnector switch.

[0008] In one possible design, the disconnect switch also includes a base disposed within the mounting space and positioned to one side of the drive assembly. A microswitch assembly is mounted on the base.

[0009] The above solution provides a mounting base and stable support for the micro switch assembly by installing a base. This reduces the probability of the micro switch assembly shaking within the installation space when the disconnecting switch is moved or subjected to impacts. This improves the reliability of the disconnecting switch.

[0010] In one possible design, the base has a positioning post, and the microswitch assembly has a positioning hole. The positioning post passes through the positioning hole to limit the movement of the microswitch assembly by the base.

[0011] With the above solution, a positioning post is set on the base and a positioning hole is set on the micro switch assembly. When the micro switch assembly is installed on the base, the positioning post passes through the positioning hole. This not only improves the installation stability of the micro switch assembly, but also the positioning post and the positioning hole cooperate to guide the installation of the micro switch assembly, making the installation of the micro switch assembly simpler.

[0012] In one possible design, the first microswitch and the second microswitch are arranged parallel to each other. The first microswitch includes a first button, and the second microswitch includes a second button. The first button and the second button are parallel to each other, and both the first button and the second button face the actuating component.

[0013] With the above solution, when the microswitch assembly is installed on the base, the first and second microswitches are arranged parallel to each other. Since the first and second microswitches are identical in size, shape, and structure, when they are parallel, the first and second buttons are also parallel. At this time, the first and second buttons face the drive assembly, making it easier for the drive assembly to press either the first or second button. This improves the reliability of the microswitch assembly and, consequently, the reliability of the isolating switch.

[0014] In one possible design, the drive assembly includes a rotating shaft and a trigger. The rotating shaft is rotatably connected to the housing and has a drive block. The trigger is rotatably connected to the housing and is positioned between the rotating shaft and the microswitch assembly. The rotating shaft drives the drive block to rotate, and the rotation of the drive block causes the trigger to control the first or second microswitch to turn on.

[0015] With the above solution, the drive assembly consists of a rotating shaft and a trigger element. The rotating shaft drives the trigger element to rotate, thereby causing the trigger element to press the first or second button. This linkage mechanism ensures that only the trigger element contacts the first or second button. Because the trigger element is small in size, it is easier and cheaper to replace if it becomes worn during use, thus effectively reducing the overall operating cost of the disconnect switch.

[0016] In one possible design, the base has a fixed shaft positioned close to the drive block. The trigger has a mounting hole through which the fixed shaft passes. The trigger rotates about the fixed shaft.

[0017] With the above design, the fixed shaft mates with the mounting hole, allowing the trigger to rotatably mount within the mounting space. The trigger is positioned between the rotating shaft and the microswitch assembly, which is mounted on the base. When the fixed shaft is mounted on the base, the trigger is fitted onto the fixed shaft, allowing it to be closer to the microswitch assembly. This saves space between the rotating shaft and the microswitch assembly, thereby improving the space utilization of the disconnector switch.

[0018] In one possible design, the trigger includes a first trigger arm and a second trigger arm. A first button is located on the rotation path of the first trigger arm, and a second button is located on the rotation path of the second trigger arm.

[0019] With the above scheme, the trigger element includes a first trigger arm and a second trigger arm. The first trigger arm can press a first button, and the second trigger arm can press a second button. Since both the first and second trigger arms can be elongated plate-like structures, this design increases the rotation radius of the trigger element without increasing its overall size. Because the first button is located on the rotation path of the first trigger arm, and the second button is located on the rotation path of the second trigger arm, a larger rotation radius reduces the likelihood of the trigger element being unable to press either the first or second button due to an excessively small rotation radius, thus improving the reliability of the disconnect switch.

[0020] In one possible design, the fixed shaft is equipped with a limit block, which is located at the end of the fixed shaft that is not connected to the base. The limit block limits the movement of the trigger element.

[0021] By using the above solution, a limiting block is set on the fixed shaft. When the trigger element is sleeved on the fixed shaft, the limiting block can limit the trigger element, which can reduce the possibility of the trigger element falling off the fixed shaft during the use of the disconnecting switch, thereby improving the reliability of the disconnecting switch.

[0022] In one possible design, the trigger also includes a reset baffle. A torsion spring is fitted onto the fixed shaft, with one end of the torsion spring abutting against the reset baffle and the other end abutting against the base.

[0023] The above solution utilizes a torsion spring to automatically reset the trigger element. Furthermore, the torsion force of the spring ensures the trigger element returns to its initial position, improving its reliability and reducing the likelihood of the disconnecting switch's shaft failing to rotate the trigger element during operation. This ultimately enhances the overall reliability of the disconnecting switch.

[0024] In one possible design, the housing is provided with reinforcing ribs that abut against the base to limit the position of the base.

[0025] The above solution, with the reinforcing ribs fitting snugly against the inner wall of the installation space, limits the base's position after it's installed, reducing the probability of displacement when the disconnecting switch shakes or is bumped. Since the base provides a mounting foundation for the microswitch assembly, reducing the probability of base displacement also reduces the probability of microswitch assembly displacement, thus improving the reliability of the microswitch assembly and consequently, the reliability of the disconnecting switch.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] A disconnecting switch is a widely used switching device in power systems. The core features of a disconnecting switch are that when it is in the open position, the contacts have a specified insulation distance and a clear disconnection mark, and when it is in the closed position, it can carry current under normal circuit conditions as well as current under abnormal conditions for a specified time.

[0042] Microswitches are a key auxiliary control element in disconnecting switches. The core function of microswitches is to monitor the open or closed status of the disconnecting switch to achieve status feedback, interlocking protection, and automated control, thereby ensuring the safe and stable operation of the power system.

[0043] In existing technology, disconnecting switches typically contain two microswitches, usually located on opposite sides of the disconnecting switch's rotating shaft. When the disconnecting switch changes from a closed to an open state, the shaft rotates. When the disconnecting switch is in the open state, the shaft triggers one of the microswitches, sending a signal to the load connected to that microswitch and thus displaying the open state of the disconnecting switch. When the disconnecting switch changes from an open to a closed state, the shaft also rotates. When the disconnecting switch is in the closed state, the shaft triggers the other microswitch, sending a signal to the load connected to that microswitch and thus displaying the closed state of the disconnecting switch.

[0044] However, the existing method of setting two microswitches on both sides of the rotating shaft will affect the space utilization of the disconnecting switch and reduce the space utilization of the disconnecting switch.

[0045] To address the aforementioned problems, this application provides a disconnecting switch. To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0046] Figure 1 This is a schematic diagram of the overall structure of the disconnecting switch provided in an embodiment of this application. Figure 1 As shown, this application provides a disconnecting switch. The disconnecting switch includes a housing 100, a drive assembly 200, and a micro switch assembly 300. The housing 100 has an installation space. The drive assembly 200 is movably disposed within the installation space. The micro switch assembly 300 is disposed on one side of the drive assembly 200, and the micro switch assembly 300 includes a first micro switch 310 and a second micro switch 320. The drive assembly 200 and the micro switch assembly 300 are linked to control the first micro switch 310 or the second micro switch 320 to be turned on.

[0047] The housing 100 includes a base 400 and a top cover. The base 400 and the top cover can be closed to form an installation space. The drive assembly 200 is disposed in the installation space and can be rotatably connected to the housing 100.

[0048] The micro switch assembly 300 includes a first micro switch 310 and a second micro switch 320, and the first micro switch 310 and the second micro switch 320 can both be disposed on one side of the drive assembly 200.

[0049] by Figure 1Taking the placement of the disconnecting switch as an example, when the disconnecting switch is in the closed state, the drive component 200 can contact the first micro switch 310, and the first micro switch 310 is in the conducting state. The load connected to the first micro switch 310 can display that the disconnecting switch is currently in the closed state. At this time, the second micro switch 320 is in the closed state.

[0050] During the process of switching the disconnector from the closed state to the open state, the drive component 200 can rotate clockwise. During the clockwise rotation of the drive component 200, the drive component 200 does not contact the first micro switch 310 or the second micro switch 320. At this time, both the first micro switch 310 and the second micro switch 320 are in the closed state.

[0051] When the disconnector is in the open state, the drive assembly 200 stops rotating. At this time, the drive assembly 200 is in contact with the second micro switch 320, which is in the on state. The load connected to the second micro switch 320 can indicate that the disconnector is currently in the open state. At this time, the first micro switch 310 is in the closed state.

[0052] As described above, in this application, the microswitch group 300 is located on one side of the drive assembly 200; that is, both the first microswitch 310 and the second microswitch 320 are located on the same side of the drive assembly 200. Compared to the prior art where the two microswitches are respectively located on both sides of the drive assembly 200, this application only utilizes the space on one side of the drive assembly 200, thus allowing the space on the other side of the drive assembly 200 to be used for other purposes. This arrangement improves the space utilization rate of the disconnector switch.

[0053] The drive assembly 200 can be used to control either the first microswitch 310 or the second microswitch 320 to be turned on. Therefore, when the first microswitch 310 and the second microswitch 320 are located on the same side of the drive assembly 200, their operation will not be affected. Furthermore, controlling two microswitches with a single trigger medium reduces the need for another trigger medium, thus minimizing the possibility of reduced reliability of the microswitch assembly 300 due to assembly errors or wear of the two trigger media, thereby improving the reliability of the isolating switch.

[0054] Figure 2 This is a schematic diagram of the base provided in an embodiment of this application. To facilitate the installation of the microswitch assembly 300, such as... Figure 1 as well as Figure 2As shown, the disconnecting switch also includes a base 400, which is disposed within the mounting space and on one side of the drive assembly 200. A microswitch assembly 300 is disposed on the base 400.

[0055] The base 400 can be a long strip-shaped structure. When the base 400 is installed in the installation space, the base 400 and the housing 100 can be detachably connected. Since the micro switch assembly 300 is installed on the base 400, the drive assembly 200 can only form a linkage with the micro switch assembly 300 when the base 400 is installed on one side of the drive assembly 200.

[0056] By providing a base 400, the micro switch assembly 300 can be mounted on a solid foundation and with stable support. This reduces the probability of the micro switch assembly 300 shaking within the mounting space when the disconnecting switch is moved or subjected to impacts. This improves the reliability of the disconnecting switch.

[0057] Figure 3 This is a schematic diagram of the micro switch assembly provided in an embodiment of this application. To further improve the installation stability of the micro switch assembly 300, such as... Figure 2 as well as Figure 3 As shown, the base 400 is provided with a positioning post 410, and the micro switch assembly 300 is provided with a positioning hole 330. The positioning post 410 passes through the positioning hole 330 so that the base 400 limits the micro switch assembly 300.

[0058] The positioning post 410 can be a columnar structure provided on the base 400, and the positioning post 410 can extend in a direction away from the base 400.

[0059] The micro switch assembly 300 includes a first micro switch 310 and a second micro switch 320. Positioning holes 330 can be provided on both the first micro switch 310 and the second micro switch 320. Based on this, the number of positioning pins 410 is at least two.

[0060] After the base 400 is installed on the housing 100, the positioning holes 330 on the first micro switch 310 and the second micro switch 320 are aligned with the corresponding positioning posts 410, and then the first micro switch 310 and the second micro switch 320 can be installed on the base 400.

[0061] In summary, the base 400 is provided with a positioning post 410, and the micro switch assembly 300 is provided with a positioning hole 330. When the micro switch assembly 300 is installed on the base 400, the positioning post 410 passes through the positioning hole 330. This not only improves the installation stability of the micro switch assembly 300, but also, with the positioning post 410 and the positioning hole 330 cooperating, it can guide the installation of the micro switch assembly 300, thus making the installation of the micro switch assembly 300 simpler.

[0062] As described above, the base 400 and the housing 100 can be detachably connected. To improve the stability of the base 400 during the use of the disconnecting switch, such as... Figure 1 as well as Figure 2 As shown, the housing 100 is also provided with reinforcing ribs, which abut against the base 400 to limit the position of the base 400.

[0063] The reinforcing rib can be installed within the installation space, and the reinforcing rib can be in the form of a long strip. When the base 400 is installed within the installation space, one side of the base 400 can abut against the reinforcing rib, and the other side of the base 400 can abut against the inner wall of the installation space.

[0064] In summary, the reinforcing ribs, in conjunction with the inner wall of the mounting space, limit the movement of the base 400 after it is installed within the space, reducing the probability of displacement of the base 400 within the mounting space when the disconnecting switch is shaken or impacted. Since the base 400 provides a mounting foundation for the microswitch assembly 300, a reduction in the probability of displacement of the base 400 also reduces the probability of displacement of the microswitch assembly 300, thus improving the reliability of the microswitch assembly 300 and consequently, the reliability of the disconnecting switch.

[0065] To improve the reliability of disconnect switches, the following improvements have been made in this application.

[0066] Please continue to refer to Figures 1 to 3 As shown, the first micro switch 310 and the second micro switch 320 are arranged parallel to each other. The first micro switch 310 includes a first button 311, and the second micro switch 320 includes a second button 321. The first button 311 and the second button 321 are parallel to each other, and both the first button 311 and the second button 321 face the drive assembly 200.

[0067] The first micro switch 310 includes a housing, a first button 311, and a contact system. The housing primarily protects the internal structure, preventing external factors such as dust, moisture, or mechanical impact from affecting the internal components. It also serves to secure and mount the micro switch, providing support and positioning for the internal parts. The first button 311 receives external force or displacement signals and transmits them to the internal mechanism of the micro switch 310, triggering its on or off state. The contact system is the core component of the first micro switch 310. The first button 311 works in conjunction with the contact system to control the on / off state of the internal circuitry of the micro switch. The on / off state of the first micro switch 310 is achieved through the contact and separation of the moving contact and the fixed contact.

[0068] The size, shape, and components of the second micro switch 320 are the same as those of the first micro switch 310, and will not be described again here.

[0069] The first micro switch 310 is provided with a first button 311, and the second micro switch 320 is provided with a second button 321. Since the first micro switch 310 and the second micro switch 320 are arranged in parallel to each other, the first button 311 and the second button 321 are also arranged in parallel to each other.

[0070] In summary, when the micro switch assembly 300 is mounted on the base 400, the first micro switch 310 and the second micro switch 320 are arranged parallel to each other. Since the first micro switch 310 and the second micro switch 320 are the same in size, shape, and structure, when the first micro switch 310 and the second micro switch 320 are parallel to each other, the first button 311 and the second button 321 are also parallel to each other. At this time, the first button 311 and the second button 321 face the drive assembly 200, which makes it easier for the drive assembly 200 to press the first button 311 or the second button 321. This improves the reliability of the micro switch assembly 300 and thus improves the reliability of the disconnect switch.

[0071] Since the first button 311 needs to be pressed when the first micro switch 310 is turned on, and the second button 321 needs to be pressed when the second micro switch 320 is turned on, the parts of the drive assembly 200 that press the first button 311 or the second button 321 are subject to severe wear.

[0072] Figure 4 This is a schematic diagram of the structure of the rotating shaft provided in an embodiment of this application. Figure 5 This is a schematic diagram of the trigger element provided in an embodiment of this application. To solve the above problems, such as... Figures 3 to 5As shown, the drive assembly 200 includes a rotating shaft 210 and a trigger 220. The rotating shaft 210 is rotatably connected to the housing 100 and is provided with a drive block 211. The trigger 220 is rotatably connected to the housing 100 and is disposed between the rotating shaft 210 and the micro switch assembly 300. The rotating shaft 210 drives the drive block 211 to rotate, and the rotation of the drive block 211 drives the trigger 220 to control the first micro switch 310 or the second micro switch 320 to be turned on.

[0073] The rotating shaft 210 can be an elongated cylindrical structure, which can rotate during the process of switching the disconnecting switch from the closed state to the open state. The driving block 211 can be a protrusion structure on the rotating shaft 210 facing the micro switch assembly 300. The driving block 211 can be integrally formed with the rotating shaft 210, or it can be set on the rotating shaft 210 after the rotating shaft 210 is formed by snap-fit ​​or adhesive.

[0074] The trigger element 220 may be a component disposed between the rotating shaft 210 and the micro switch assembly 300, for contacting the first button 311 or the second button 321. During the rotation of the rotating shaft 210, the trigger element 220 rotates synchronously. When the disconnecting switch is in the closed state, the trigger element 220 presses the first button 311, thereby turning on the first micro switch 310. When the disconnecting switch is in the open state, the trigger element 220 presses the second button 321, causing the second micro switch 320 to turn on.

[0075] In summary, the drive assembly 200 consists of a rotating shaft 210 and a trigger element 220. The rotating shaft 210 drives the trigger element 220 to rotate, thereby causing the trigger element 220 to press the first button 311 or the second button 321. This linkage mechanism ensures that only the trigger element 220 contacts the first button 311 or the second button 321. Because the trigger element 220 is small in size, it is easier to replace if it is worn out during use, and the replacement cost is lower, thus effectively reducing the overall operating cost of the disconnect switch.

[0076] Further, please continue to refer to Figure 1 , Figure 4 as well as Figure 5 As shown, the trigger 220 includes a first trigger arm 222 and a second trigger arm 223. The first button 311 is located on the rotation path of the first trigger arm 222, and the second button 321 is located on the rotation path of the second trigger arm 223.

[0077] Both the first trigger arm 222 and the second trigger arm 223 can be elongated plate-like structures, and the first trigger arm 222 and the second trigger arm 223 are set at a certain angle. When the trigger element 220 is located between the rotating shaft 210 and the micro switch group 300, the drive block 211 can be located between the first trigger arm 222 and the second trigger arm 223.

[0078] During the rotation of the shaft 210, the drive block 211 can push the second trigger arm 223 to cause the trigger element 220 to rotate. During the process of the drive block 211 pushing the second trigger arm 223, the second trigger arm 223 can press the second button 321. Alternatively, during the rotation of the shaft 210, the drive block 211 can push the first trigger arm 222 to cause the trigger element 220 to rotate. During the process of the drive block 211 pushing the first trigger arm 222, the first trigger arm 222 can press the first button 311.

[0079] In summary, the trigger element 220 includes a first trigger arm 222 and a second trigger arm 223. The first trigger arm 222 can press the first button 311, and the second trigger arm 223 can press the second button 321. Since both the first trigger arm 222 and the second trigger arm 223 can be elongated plate-like structures, this design increases the rotation radius of the trigger element 220 without increasing its overall size. Because the first button 311 is located on the rotation path of the first trigger arm 222, and the second button 321 is located on the rotation path of the second trigger arm 223, a larger rotation radius reduces the likelihood of the trigger element 220 failing to press either the first button 311 or the second button 321 due to an excessively small rotation radius, thereby improving the reliability of the disconnect switch.

[0080] like Figure 2 as well as Figure 5 As shown, the base 400 is provided with a fixed shaft 420, which is located near the drive block 211. The trigger 220 is provided with a mounting hole 221, through which the fixed shaft 420 passes. The trigger 220 rotates about the fixed shaft 420 as its axis.

[0081] The fixed shaft 420 can be an elongated cylindrical structure mounted on the base 400. The fixed shaft 420 can be vertically mounted on the base 400 and extend in a direction away from the base 400.

[0082] The mounting hole 221 can be a pre-set through hole structure on the trigger 220. This mounting hole 221 is typically a round hole to accommodate the cylindrical fixed shaft 420. When the trigger 220 is positioned within the mounting space, it can be fitted onto the fixed shaft 420. As the rotating shaft 210 drives the trigger 220 to rotate, the trigger 220 can rotate around the fixed shaft 420.

[0083] In summary, the fixed shaft 420, in conjunction with the mounting hole 221, allows the trigger element 220 to rotatably mount within the mounting space. The trigger element 220 is positioned between the rotating shaft 210 and the micro switch assembly 300, which is mounted on the base 400. When the fixed shaft 420 is mounted on the base 400, the trigger element 220 is fitted onto it, allowing it to be closer to the micro switch assembly 300. This saves space between the rotating shaft 210 and the micro switch assembly 300, thereby improving the space utilization of the disconnector switch.

[0084] Please continue to refer to Figure 2 as well as Figure 5 As shown, the fixed shaft 420 is also provided with a limiting block 421, which is located at the end of the fixed shaft 420 that is not connected to the base 400. The limiting block 421 limits the trigger 220.

[0085] As described above, the fixed shaft 420 is vertically mounted on the base 400 and extends in a direction away from the base 400. Therefore, the limiting block 421 can be a protruding structure provided on the side wall of the end of the fixed shaft 420 away from the base 400.

[0086] The limiting block 421 can be integrally formed with the fixed shaft 420. In this case, when installing the trigger 220, the trigger 220 can be placed on the base 400 first, then the end of the fixed shaft 420 without the limiting block 421 can be passed through the mounting hole 221 on the trigger 220, and finally the end of the fixed shaft 420 without the limiting block 421 can be fixedly connected to the base 400 to complete the installation of the trigger 220.

[0087] The limiting block 421 can also be installed on the end of the fixed shaft 420 away from the base 400 by means of adhesion or snap-fit ​​after the fixed shaft 420 is formed. In this case, when installing the trigger 220, if the fixed shaft 420 and the base 400 are integrally formed, the trigger 220 can be first sleeved on the fixed shaft 420, and then the limiting block 421 can be fixed on the end of the fixed shaft 420 away from the base 400 to complete the installation of the trigger 220. If the fixed shaft 420 and the base 400 are formed separately and then assembled, the fixed shaft 420 and the base 400 can be fixedly connected first, then the trigger 220 can be sleeved on the fixed shaft 420, and finally the limiting block 421 can be fixed on the end of the fixed shaft 420 away from the base 400 to complete the installation of the trigger 220.

[0088] In summary, by setting a limiting block 421 on the fixed shaft 420, when the trigger 220 is sleeved on the fixed shaft 420, the limiting block 421 can limit the trigger 220, which can reduce the possibility of the trigger 220 falling off the fixed shaft 420 during the use of the disconnecting switch, thereby improving the reliability of the disconnecting switch.

[0089] Figure 6 This is an assembly diagram of the trigger and the base provided in an embodiment of this application. Figure 1 as well as Figure 6 As shown, the trigger 220 is also provided with a reset baffle 224. A torsion spring 500 is sleeved on the fixed shaft 420. One end of the torsion spring 500 abuts against the reset baffle 224, and the other end of the torsion spring 500 abuts against the base 400.

[0090] The reset baffle 224 can be a plate-like structure provided on the trigger 220, and the reset baffle 224 can be provided on the side of the trigger 220 facing the base 400. When the torsion spring 500 is sleeved on the fixed shaft 420, the reset baffle 224 can block the side of the torsion spring 500 close to the micro switch assembly 300. At this time, the torsion spring 500 can abut against the side of the reset baffle 224 facing away from the micro switch, and the other end of the torsion spring 500 can abut against the base 400.

[0091] With the above settings, the torsion spring 500 can automatically reset the trigger element 220. Furthermore, under the torque of the torsion spring 500, the trigger element 220 can return to its initial position, thus improving the reliability of the trigger element 220 and reducing the possibility of the shaft 210 failing to drive the trigger element 220 to rotate during use of the disconnecting switch, thereby enhancing the overall reliability of the disconnecting switch.

[0092] In some practical applications, two sets of microswitch groups 300 can be installed inside the disconnecting switch. In this case, disconnecting switch groups can be installed on both sides of the drive assembly 200. That is, a first microswitch 310 and a second microswitch 320 can be installed on one side of the drive assembly 200, and the first microswitch 310 and the second microswitch 320 can also be installed on the other side of the drive assembly 200. This allows the disconnecting switch to have four microswitches, thereby further increasing the space utilization rate of the disconnecting switch.
