Description

[0001] This application is a divisional application of the invention patent application filed on December 30, 2025, with application number 202512040425.6, entitled "An operating mechanism for a disconnecting switch and a disconnecting switch". Technical Field

[0002] This disclosure relates to the field of disconnecting switch technology, specifically to an operating mechanism for a disconnecting switch and a disconnecting switch. Background Technology

[0003] A disconnecting switch is a device used to disconnect or connect circuits to ensure the safety of electrical equipment during maintenance or repair. To ensure the timely switching of the disconnecting switch, an energy storage operating mechanism is generally used. The rotation of the input shaft causes an energy storage component to store energy, which is then released to the output shaft after storage, thus transmitting force to the output shaft and causing it to rotate rapidly. This allows the disconnecting switch to change its operating state more quickly, improving the timeliness of its switching. However, the operating mechanisms currently used have relatively large forces stored and released by the energy storage component, resulting in poor reliability and stability during the force transmission process from the energy storage component to the output shaft. Furthermore, the energy storage component is prone to aging and damage, leading to a shorter service life. Summary of the Invention

[0004] To overcome the problems existing in the related art, an exemplary embodiment of this disclosure provides an operating mechanism for a disconnecting switch in a first aspect. The operating mechanism of the disconnecting switch includes: an output shaft for rotating to drive the moving contact of the disconnecting switch to rotate; an input shaft for rotating to drive the output shaft to rotate; a transmission member for being driven by the input shaft and coaxially connected to the output shaft, for rotating under the drive of the input shaft and transmitting to the output shaft to cause the output shaft to rotate; an energy storage component for storing energy during the rotation of the output shaft and releasing energy to the output shaft after storage to assist the rotation of the output shaft; and a limiting member for being driven by the transmission member and limiting the energy storage component to limit the energy storage component; wherein, there is an idle stroke in the rotational connection between the transmission member and the output shaft.

[0005] In some embodiments, under the drive of the transmission member, the output shaft rotates at an angle greater than the angle of rotation of the limiting member.

[0006] In some embodiments, the operating mechanism of the disconnect switch includes: a first input port, which is located on the top of the input shaft and is in the shape of a square groove; a second input port, which is located on the surface of the transmission member and is in the shape of a square groove; and a protruding cross-shaped structure is formed at one end of the output shaft for connecting with the moving contact of the disconnect switch.

[0007] In some embodiments, the input shaft rotates at least 90°, the angle by which the transmission member and the output shaft rotate and drive the moving contact of the disconnecting switch to rotate is greater than or equal to 100° and less than or equal to 145°, and the rotation angle of the limiting member is an acute angle.

[0008] In some embodiments, the rotation angle of the transmission component is smaller than the rotation angle of the output shaft.

[0009] In some embodiments, the transmission component includes an internal gear and an external gear, the internal gear being drivenly connected to the input shaft, the external gear being drivenly connected to the limiting component, and the gear ratio between the internal gear and the external gear being 1:3.

[0010] In some embodiments, the energy storage component includes: a mounting member connected to the output shaft and rotating with the rotation of the output shaft; and an energy storage spring, one end of which is connected to the mounting member and the other end of which is connected to an energy storage spring fixing shaft disposed on the housing of the disconnecting switch.

[0011] In some embodiments, one end of the limiting member is used to connect with a limiting member fixing shaft provided on the housing of the disconnecting switch, and the limiting member fixing shaft is coaxially arranged with the energy storage spring fixing shaft.

[0012] In some embodiments, when the input shaft rotates 90°, the transmission member drives the limiting member to rotate 60° around the fixed axis of the limiting member. The energy storage spring is compressed as the limiting member rotates. After the energy storage spring reaches a set compression amount, it enters the energy release stage. The energy released by the energy storage spring is converted into a driving torque on the output shaft.

[0013] Secondly, this disclosure also provides a disconnecting switch, the disconnecting switch including an operating mechanism as described in the first aspect; a housing covering the outside of the operating mechanism; and a switch body including a moving contact assembly, the moving contact assembly being connected to the output shaft of the operating mechanism and rotating synchronously with the output shaft.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0015] According to the operating mechanism of the disconnecting switch provided in this disclosure, energy can be stored in the energy storage component and released to the output shaft, thereby assisting the output shaft to rotate rapidly. This enables the disconnecting switch to switch on and off quickly, improving its reliability. Limiting the energy storage component with a limiting component provides support, preventing malfunctions and aging caused by the large transmission force of the energy storage component. This effectively improves the reliability and stability of the energy storage component, extends its service life, and further enhances the operational reliability and stability of the disconnecting switch, extending its service life as well.

The structures and scales shown in the diagram do not necessarily represent their actual positions or scales in the equipment and are only used to aid in understanding this application.

[0019] To solve the above technical problems, such as Figure 1 As shown, this disclosure provides an operating mechanism for a disconnecting switch, which may include: an output shaft 110, an input shaft 120, a transmission component 130, an energy storage component 140, and a limiting component 150.

[0020] The output shaft 110 is used to rotate to drive the moving contact of the disconnecting switch. The output shaft 110 can be connected to the moving contact of the disconnecting switch, so that the rotation of the output shaft 110 drives the rotation of the moving contact of the disconnecting switch. By causing the moving contact of the disconnecting switch to rotate with the output shaft 110, the moving contact can be connected or separated from the stationary contact, thereby making the disconnecting switch open or closed, and the operating state of the disconnecting switch can be changed quickly.

[0021] The input shaft 120 is used to rotate to drive the output shaft 110 to rotate. The input shaft 120 can be directly connected to the output shaft 110, so that rotation of the input shaft 120 directly drives the output shaft 110 to rotate accordingly. Alternatively, the input shaft 120 can be connected to the output shaft 110 via a transmission member 130, so that rotation of the input shaft 120 drives the transmission member 130 to rotate, and the rotational motion is transmitted to the output shaft 110 through the transmission member 130, thus enabling the input shaft 120 to drive the rotation of the output shaft 110.

[0022] The transmission component 130 is driven by the input shaft 120 and coaxially connected to the output shaft 110. It rotates under the drive of the input shaft 120 and transmits power to the output shaft 110, causing the output shaft 110 to rotate. The transmission component 130 can be connected to both the input shaft 120 and the output shaft 110. When the input shaft 120 rotates, the transmission component 130 rotates under its drive, causing the output shaft 110 to rotate. The output shaft 110 is coaxially arranged with the transmission component 130 and can rotate with it. The transmission component 130 can be fixedly connected to the input shaft 120, or it can be integrally manufactured with the input shaft 120. Alternatively, the transmission component 130 and the input shaft 120 can be fixedly connected to each other via a fixed connector, allowing the input shaft 120 and the transmission component 130 to rotate synchronously. The transmission component 130 can transmit the rotation of the input shaft 120 to the output shaft 110, thereby enabling the output shaft 110 to rotate with the transmission component 130.

[0023] Energy storage component 140, connected to output shaft 110, stores energy during the rotation of output shaft 110 and releases it to output shaft 110 after storage to assist in the rotation of output shaft 110. Energy storage component 140 can be connected to output shaft 110. When output shaft 110 and transmission component 130 rotate under the drive of input shaft 120, energy storage component 140 stores energy. When energy storage component 140 reaches its maximum stored energy, it can release it to output shaft 110, thereby further driving output shaft 110 to rotate rapidly. This causes the connection state of the moving contact and stationary contact connected to output shaft 110 to change rapidly, thus enabling the disconnector switch to quickly change its operating state from connected to disconnected, or from disconnected to connected.

[0024] A limiting member 150 is driven by the transmission member 130 and also limits the energy storage component 140 to restrict its movement. Because the energy storage component 140 generates significant force during its release to the output shaft 110 after energy storage, prolonged operation may lead to aging or damage, resulting in a shorter lifespan. Therefore, a limiting member 150 is provided, which limits the energy storage component 140 by providing this limiting connection. One or more limiting members 150 may be located around the transmission member 130, with one end of each member drivingly connected to the transmission member 130, allowing the limiting member 150 to rotate or oscillate under the drive of the transmission member 130. Since the transmission member 130 is coaxially connected to the output shaft 110, it can drive the output shaft 110 to rotate synchronously. Since the energy storage component 140 is connected to the output shaft 110 and rotates with the output shaft 110 during energy storage, the limiting member 150 can rotate synchronously with the energy storage component 140. This ensures the synchronization of the limiting member 150 and the energy storage component 140, and guarantees the limiting stability of the limiting member 150 on the energy storage component 140. Through the limiting member 150, the energy storage component 140 is limited during the rapid rotation of the output shaft 110 driven by the energy storage component 140, thereby effectively improving the reliability and safety of the transmission force of the energy storage component 140. The limiting member 150 can be connected to the transmission member 130. When the transmission member 130 rotates with the input shaft 120, the limiting member 150 can move with the transmission member 130, enabling the limiting member 150 and the energy storage component 140 to move synchronously, further ensuring the limiting stability of the energy storage component 140.

[0025] According to the operating mechanism of the disconnecting switch provided in this embodiment, through the output shaft 110, input shaft 120, and transmission component 130, the rotation of the input shaft 120 can be stably and continuously transmitted to the output shaft 110 via the transmission component 130. This allows the output shaft 110 to quickly drive the moving contact to rotate, thereby ensuring that the disconnecting switch can perform on / off operations in a timely manner and improving the response speed of the disconnecting switch. By setting an energy storage component 140 connected to the output shaft 110, the energy storage component 140 can synchronously store energy during the rotation of the output shaft 110 driven by the input shaft 120 and the transmission component 130, and release the stored energy to the output shaft 110, thereby assisting the rotation of the output shaft 110. This allows the output shaft 110 to rotate rapidly in a shorter time, causing the connection state of the moving and stationary contacts of the disconnecting switch to change quickly, thus significantly improving the efficiency of the disconnecting switch and improving its operational reliability. By setting a limiting member 150 connected to the transmission component 130 and cooperating with the energy storage component 140, the energy storage component 140 can be limited and supported, thereby restricting its displacement during energy storage and energy release to the output shaft 110. This avoids problems such as positional displacement of the energy storage component 140 due to large transmission force, or fatigue and damage caused by excessive transmission force. It effectively reduces wear and fatigue of the energy storage component 140, improves its stability and safety during operation, extends its service life, and saves costs. Therefore, it further improves the overall operational stability and reliability of the disconnector switch.

[0026] In some embodiments, such as Figure 1 As shown, the energy storage component 140 may include: a mounting component 141 and an energy storage spring 142.

[0027] Mounting member 141 is connected to output shaft 110 and rotates with output shaft 110. Specifically, mounting member 141 can be sleeved onto output shaft 110 so that it can rotate with output shaft 110. A mounting portion for connecting to energy storage spring 142 can be formed on the periphery of mounting member 141, allowing energy storage spring 142 to move synchronously with mounting member 141. Mounting member 141 rotates with output shaft 110, causing energy storage spring 142 to compress and store energy. When energy storage spring 142 has finished storing energy, it can release from mounting member 141 connected to output shaft 110, causing mounting member 141 to rotate rapidly, further driving output shaft 110 to rotate rapidly.

[0028] like Figure 3 , Figure 4 , Figure 6As shown, the energy storage spring 142 has one end connected to the mounting member 141 and the other end connected to the energy storage spring fixing shaft provided on the housing 210 of the disconnecting switch. One end of the energy storage spring 142 can be connected to the mounting member 141, so that the mounting member 141 drives the energy storage spring 142 to move synchronously as it rotates with the output shaft 110. One end of the energy storage spring 142 is connected to the mounting member 141, and the other end is connected to the housing 210 of the disconnecting switch. The housing 210 of the disconnecting switch can be provided with an energy storage spring fixing shaft for connecting to the energy storage spring 142. The energy storage spring 142 can rotate around the energy storage spring fixing shaft, so that during the rotation of the input shaft 120, one end of the energy storage spring 142 is rotatably connected to the energy storage spring fixing shaft, and the other end can move with the rotation of the mounting member 141. This causes the energy storage spring 142 to be compressed during the rotation of the mounting member 141, thereby enabling the energy storage spring 142 to store energy. Once the energy storage spring 142 has completed storing energy, it can release energy to the mounting component 141, thereby driving the mounting component 141 and the output shaft 110 to rotate rapidly. This allows the moving contact connected to the output shaft 110 to move rapidly, quickly changing the connection state between the moving and stationary contacts, thus changing the on / off state of the disconnecting switch. Therefore, the disconnecting switch can be quickly connected or disconnected, resulting in a higher response speed.

[0029] According to the operating mechanism of the disconnecting switch provided in this embodiment, the energy storage component 140 can achieve a more stable and controllable energy storage and release process during the rotation of the output shaft 110 by means of the mounting member 141 sleeved on the output shaft 110 and the energy storage spring 142 cooperating with the mounting member 141. The mounting member 141 is sleeved on the output shaft 110 and rotates synchronously with it, so that the mounting member 141 can directly drive the energy storage spring 142 to compress. The mounting part provided on the periphery of the mounting member 141 can reliably limit the position of one end of the energy storage spring 142, so that the energy storage spring 142 maintains the same force direction during the compression process, further improving the stability and energy storage efficiency of the energy storage process. The other end of the energy storage spring 142 is connected to the disconnector housing 210 via the energy storage spring fixed shaft, so that the energy storage spring 142 can rotate with the mounting part 141 around the fixed shaft and gradually compress. During the process of the input shaft 120 driving the output shaft 110 to rotate, the energy storage spring 142 can stably and continuously complete the energy storage. After the energy storage reaches the set amount, the energy storage spring 142 can quickly and centrally release energy to the mounting part 141, pushing the mounting part 141 and the output shaft 110 to accelerate rotation instantaneously, so that the moving contact driven by the output shaft 110 can achieve position switching at a faster speed, significantly improving the response speed of the disconnector action.

[0030] In some embodiments, such as Figure 2-6 As shown, the energy storage component 140 includes a plurality of energy storage springs 142, such as Figure 7As shown, multiple mounting shafts 1411 extend radially along the periphery of the mounting member 141, and multiple energy storage springs 142 are correspondingly sleeved on the mounting shafts 1411. Multiple mounting shafts 1411 can extend radially along the periphery of the mounting member 141, and the outer diameter of the mounting shaft 1411 can match the inner diameter of the energy storage spring 142, allowing the energy storage spring 142 to be sleeved on the mounting shaft 1411. Furthermore, during the rotation of the mounting member 141, the energy storage spring 142 can be compressed along with the rotation of the radially extending mounting shaft 1411, causing the energy storage spring 142 to store energy. After the energy storage spring 142 has completed storing energy, it can output energy to the mounting shaft 1411, driving the mounting shaft 1411 and the entire mounting member 141 to rotate rapidly, thereby improving the response efficiency of the disconnector's operating mechanism and thus improving the overall response efficiency of the disconnector. Specifically, as... Figure 1 As shown, the energy storage component 140 of the operating mechanism of the disconnecting switch may include four energy storage springs 142. Energy storage spring fixing shafts are respectively provided at the four corners of the disconnecting switch housing 210. The four energy storage springs 142 are respectively disposed on the periphery of the mounting member 141. The mounting member 141 may extend radially to form four mounting shafts 1411, and the four energy storage springs 142 may be correspondingly sleeved on the outside of the mounting shafts 1411. The four energy storage springs 142 may have the same length and the same stiffness coefficient, enabling the input shaft 120 to rotate and indirectly drive the mounting member 141 to rotate, such as... Figure 2 , Figure 3 As shown, during the compression and energy storage process of the energy storage springs 142, the four energy storage springs 142 have the same deformation, thus ensuring that the energy stored by the four energy storage springs 142 is equal. Therefore, after the four energy storage springs 142 have completed energy storage, they can synchronously transfer energy to the mounting component 141, enabling the mounting component 141 and the output shaft 110 to rotate quickly and stably, thereby effectively improving the overall working stability and reliability of the disconnector switch. Furthermore, setting the four energy storage springs 142 to synchronously store and release energy effectively reduces the force requirement on each individual energy storage spring 142, effectively extending the service life of the energy storage springs 142. Figure 4 As shown, the four energy storage springs 142 can be arranged in pairs opposite each other, so that the four energy storage springs 142 can be respectively arranged on the diagonal of a rectangle centered on the axis of the output shaft 110. This allows the operating mechanism of the disconnect switch to accommodate longer energy storage springs 142. Furthermore, due to the longer spring length and stroke, installation and disassembly are easier. Figure 4 As shown, when the two energy storage springs 142 on opposite sides are collinear, the deformation of the energy storage spring 142 is at its maximum, and the energy storage spring 142 completes energy storage, as... Figure 5 , Figure 6As shown, when the input shaft 120 continues to rotate, it drives the mounting component 141 to rotate, causing the energy storage spring 142 to quickly release energy to the mounting component 141, thereby pushing the mounting component 141 to rotate rapidly, driving the output shaft 110 to rotate rapidly, causing the moving contact of the disconnecting switch to disconnect or change its connection state with the stationary contact, thus enabling the disconnecting switch to achieve rapid connection or rapid disconnection. Specifically, as... Figure 4 As shown, the four energy storage spring fixing shafts can be formed into a rectangle, and the shorter side of the rectangle can be parallel to the axial direction of the input shaft 120. Therefore, as... Figure 4 As shown, for the four mounting shafts 1411 formed by the radial extension of the mounting member 141, the included angle formed by the two mounting shafts 1411 located on the left side of the input shaft 120 is less than 90°, and the included angle formed by the two mounting shafts 1411 located on the right side of the input shaft 120 is less than 90°. This allows for a wider rectangle, enabling the use of longer energy storage springs 142 mounted on the mounting shafts 1411. The longer the energy storage spring 142, the greater its maximum compression, thus allowing it to store more energy. Therefore, this design effectively improves the energy storage efficiency and energy storage capacity of the energy storage spring 142, enabling it to store energy more quickly. Furthermore, a longer energy storage spring 142 allows for greater torsional space during movement. When the energy storage spring 142 is short, its limited torsional space may prevent successful energy output to the output shaft 110, causing the isolating switch to jam. The longer length of the energy storage spring 142 allows for greater torsional flexibility when releasing energy. Furthermore, the limiting effect of the limiting component prevents excessive torsion and potential failure of the energy storage spring 142 during energy release. This ensures stable and reliable torsion of the energy storage spring 142 and the release of energy to the output shaft 110, resulting in faster switching and higher response efficiency of the disconnecting switch. Simultaneously, this embodiment further enhances the overall stability and reliability of the energy storage spring 142, the energy storage component, and the operating mechanism, thereby improving the overall reliability of the disconnecting switch.

[0031] According to the operating mechanism of the disconnecting switch provided in this embodiment, by forming a mounting shaft 1411 extending radially around the mounting member 141 and sleeved one end of the energy storage spring 142 on the mounting shaft 1411, the overall stability of the energy storage assembly 140 can be improved, so that each energy storage spring 142 can rotate synchronously with the mounting member 141 and be compressed. When the mounting member 141 rotates under the drive of the input shaft 120, each energy storage spring 142 can be compressed and stored synchronously, and then can jointly output energy to the mounting member 141, pushing the mounting member 141 and the output shaft 110 to rotate rapidly, thereby significantly enhancing the working efficiency and response speed of the operating mechanism, and further improving the response efficiency of the disconnecting switch action. When the energy storage component 140 includes four energy storage springs 142, and their lengths and stiffness coefficients are kept consistent, the deformation of the four energy storage springs 142 during compression is consistent, thus ensuring equal stored energy. This allows the four energy storage springs 142 to release equal energy synchronously, effectively avoiding problems such as rotational sway of the mounting component 141 caused by uneven force on the energy storage springs 142. This also allows the output shaft 110 to maintain rapid and stable acceleration at the moment of energy release. Therefore, this embodiment effectively improves the response speed, reliability, and stability of the disconnector switch operating mechanism, making the overall operation of the disconnector switch more reliable and stable, and further extending the service life of the disconnector switch.

[0032] In some embodiments, the energy storage component includes four energy storage springs 142; the mounting member 141 includes four mounting shafts 1411, which are respectively connected to the four energy storage springs 142. Two mounting shafts 1411 form a group, such that the two groups of mounting shafts 1411 are respectively located on both sides of the mounting member, and the included angle between two mounting shafts 1411 located on the same side is an acute angle. The mounting member can extend radially to form four mounting shafts 1411, wherein any two adjacent mounting shafts 1411 can be selected to form a mounting shaft group, such that the included angle formed by the two mounting shafts 1411 is an acute angle, and the two mounting shaft groups can be respectively located on both sides of the mounting member. The included angle between two adjacent mounting shafts 1411 belonging to different mounting shaft groups can be an obtuse angle. The energy storage assembly may include four energy storage springs 142, each of which is respectively mounted on a mounting shaft 1411. The energy storage springs 142 are fitted onto the mounting shaft 1411 to limit their movement, preventing uneven force distribution and ensuring consistent force on the output shaft. This also effectively prevents failure caused by the energy storage springs 142 slipping off the mounting components. Furthermore, the use of four mounting shafts 1411 for the four energy storage springs 142, along with the stable arrangement of the shafts and springs, ensures a more stable connection and transmission between the energy storage springs 142 and the mounting components. This effectively improves the safety and stability of the energy storage assembly during energy storage and release, further enhancing the stability of the disconnector switch operation.

[0033] In some embodiments, such as Figure 11 As shown, one end of the limiting member 150 is used to connect with a limiting member fixing shaft provided on the housing 210 of the disconnecting switch. The limiting member fixing shaft is coaxially arranged with the energy storage spring fixing shaft. The limiting member 150 may have a positioning groove 151, and the energy storage spring 142 may be disposed in the positioning groove 151. And as... Figure 8As shown, the main body of the limiting member 150 can be a plate-like structure, arranged along the extending direction of the energy storage spring 142. A protrusion can be formed perpendicular to the main body at the center of the limiting member 150. The height of the two sides of the protrusion perpendicular to the extending direction of the energy storage spring 142 can be higher than the height of the center of the protrusion, thus forming a positioning groove 151 for mounting the energy storage spring 142. The center of the protrusion can accommodate the energy storage spring 142, and the height of the two sides of the protrusion perpendicular to the extending direction of the energy storage spring 142 is greater than the height of the center of the protrusion. When the energy storage spring 142 is installed in the positioning groove 151, the two radial sides of the energy storage spring 142 can abut against the two sides of the protrusion, thereby ensuring the energy storage spring 142 remains stable under the constraint of the positioning groove 151 and preventing radial displacement. One end of the limiting member 150 can be rotatably connected to a limiting member fixing shaft provided on the housing 210 of the disconnecting switch, allowing the limiting member 150 to rotate about the limiting member fixing shaft. The limiting member's fixing shaft and the energy storage spring's fixing shaft are coaxially arranged, thus ensuring the cooperation between the limiting member 150 and the energy storage spring 142. During the operation of the disconnector's operating mechanism, one end of the energy storage spring 142 is sleeved on the mounting shaft 1411 of the mounting member 141, and the other end is connected to the disconnector's housing 210, achieving length-direction limiting and effectively restricting the offset of the energy storage spring 142. When the energy storage spring 142 rotates on the input shaft 120, the transmission member 130, the output shaft 110, and the mounting member 141 can rotate, causing the energy storage spring 142 to compress and store energy as the mounting member 141 rotates. After energy storage is complete, the energy storage spring 142 can release energy to the mounting member 141 to accelerate its rotation, thereby further accelerating the rotation of the output shaft 110. One end of the limiting member 150 is connected to the transmission member 130 and can rotate with the transmission member 130. The limiting member 150 and the energy storage spring 142 move synchronously. By setting a limiting member 150, the energy storage spring 142 is installed in the positioning groove 151 of the limiting member 150. This ensures the stability of the energy storage spring 142 during the compression and energy storage process. Since the limiting member 150 is a rigid component, it effectively prevents the energy storage spring 142 from laterally bending, which could lead to uncontrollable deformation and energy leakage, thus improving the safety and reliability of the energy storage spring 142 during the compression and energy storage process. The energy storage spring 142 installed in the positioning groove 151 of the limiting member 150 ensures the stable release of energy during the energy release process, preventing uneven force application or failure of the energy storage spring 142 due to lateral bending during energy release. This effectively improves the safety and stability of the energy storage component 140 during the energy release process of the energy storage spring 142.

[0034] According to this embodiment, by forming multiple mounting shafts 1411 extending radially along the periphery of the mounting member 141, and sleeved with a corresponding energy storage spring 142 on each mounting shaft 1411, the energy storage assembly 140 is composed of multiple cooperating energy storage springs 142, which can significantly improve the balance of the energy storage process and the stability of the energy release process. The multiple mounting shafts 1411 allow each energy storage spring 142 to rotate synchronously with the mounting member 141 and be compressed, achieving multi-point synchronous energy storage. This avoids fatigue, misalignment, or damage problems caused by concentrated force on a single energy storage spring 142 under high loads, thereby improving the overall reliability of the energy storage assembly 140. Therefore, this embodiment not only improves the response speed of the disconnector operating mechanism but also significantly improves the stability and consistency of the energy release process, making the overall operation of the disconnector more reliable and stable, and further extending the service life of the disconnector.

[0035] In some embodiments, such as Figure 1 As shown, the positioning groove 151 can be located between the middle of the energy storage spring 142 and the end connected to the outer casing 210. The energy storage spring 142 can be installed in the positioning groove 151, such that the length direction of the energy storage spring 142 is collinear with the extension direction of the main body of the limiting member 150. The positioning groove 151 can be located between the middle of the energy storage spring 142 and the end connected to the outer casing 210, so that the positioning groove 151 can abut against the side of the energy storage spring 142 near the side connected to the outer casing 210. Since the energy storage spring 142 may bend laterally during the energy storage and release process, resulting in uncontrollable deformation and energy leakage, and the location of the lateral bending of the energy storage spring 142 is generally located in the middle near the side connected to the outer casing 210, the positioning groove 151 can be located between the middle of the energy storage spring 142 and the end connected to the outer casing 210, thereby providing better support and limiting effect for the energy storage spring 142. Specifically, the positioning groove 151 and the energy storage spring 142 can abut at one-third of the length of the energy storage spring 142, and the abutment point between the energy storage spring 142 and the positioning groove 151 is near the end where the energy storage spring 142 is connected to the outer shell 210. In this case, the limiting member 150 can limit the energy storage spring 142 through the positioning groove 151, and has a better limiting effect, ensuring that the energy storage spring 142 remains stable in the radial and length directions during the compression energy storage and release process, avoiding lateral bending or uncontrollable deformation, thereby preventing energy leakage and improving the safety and reliability of the energy storage spring 142 during the compression energy storage and release process.

[0036] According to this embodiment, by forming a positioning groove 151 for mounting the energy storage spring 142 on the limiting member 150, and by rotatably connecting one end of the limiting member 150 to the limiting member fixing shaft provided on the disconnector housing 210, and by coaxially arranging the limiting member fixing shaft and the energy storage spring fixing shaft, the limiting member 150 can provide effective support and stable constraint during the energy storage and release process of the energy storage spring 142. The main body of the limiting member 150 is arranged along the extending direction of the energy storage spring 142, and the height of the two sides of the protrusion formed vertically in the middle is greater than its center height, so that a positioning groove 151 capable of accommodating the energy storage spring 142 is formed in the middle, so that after the energy storage spring 142 is installed, the energy storage spring 142 abuts against the sidewall of the protrusion on both radial sides. Therefore, the positioning groove 151 can provide double-sided limiting for the energy storage spring 142, preventing radial displacement of the energy storage spring 142 during compression or energy release, effectively avoiding uncontrolled deformation, energy leakage, or fatigue damage caused by lateral bending of the energy storage spring 142 in traditional structures. Thus, this embodiment can effectively ensure the force balance of the energy storage spring 142 throughout the entire compression and energy release process, improving the overall reliability of the energy storage component 140, and enabling the mounting component 141 and the output shaft 110 to obtain a more stable, continuous, and controllable driving force, thereby further improving the stability, speed, and long-term reliability of the disconnecting switch's on / off action.

[0037] In some embodiments, such as Figure 10 As shown, the transmission component 130 may include an external gear 131, such as... Figure 8 As shown, a transmission sector tooth 152 is formed at the end of the limiting member 150 away from the outer casing 210, and the transmission sector tooth 152 meshes with the external gear 131. The transmission member 130 may include an external gear 131 structure, and teeth may be formed on the periphery of the transmission member 130. The end of the limiting member 150 away from the outer casing 210 may have a transmission sector tooth 152 that can mesh with the external gear 131. When the transmission member 130 rotates with the rotation of the input shaft 120, the limiting member 150 can rotate around the fixed shaft of the limiting member under the drive of the external gear 131 through the transmission sector tooth 152 that meshes with the external gear 131. Since the transmission member 130 rotates with the output shaft 110 and the mounting member 141, and the fixed shaft of the limiting member is coaxial with the fixed shaft of the energy storage spring, the limiting member 150 and the energy storage spring 142 can move synchronously. Since the limiting member 150 is a rigid member and is connected to the transmission member 130 through gear meshing, the mechanical transmission between the transmission member 130 and the limiting member 150 is more stable and has higher reliability compared to the energy storage spring 142.

[0038] According to the operating mechanism of the disconnecting switch provided in this embodiment, by setting the transmission member 130 as an external gear 131 structure and forming a transmission sector tooth 152 that meshes with the external gear 131 at the end of the limiting member 150 away from the outer casing 210, mechanical meshing drive between the transmission member 130 and the limiting member 150 is achieved. During the process of the input shaft 120 driving the transmission member 130 to rotate, the transmission sector tooth 152 can transmit the rotational force of the external gear 131 to the limiting member 150, causing the limiting member 150 to rotate around the limiting member fixed axis, thereby achieving synchronous movement of the limiting member 150, the mounting member 141, and the energy storage spring 142. Since the limiting member fixed axis and the energy storage spring fixed axis are coaxially arranged, the gear meshing transmission can ensure the synchronicity between the limiting member 150 and the energy storage spring 142, so that the energy storage spring 142 is stably stressed along a predetermined trajectory during energy storage and release, avoiding radial offset or uneven force application. By using gear meshing between the transmission component 130 and the limiting component 150, compared to driving methods relying solely on non-rigid mechanisms such as the energy storage spring 142, the stability and reliability of the transmission can be further improved. Simultaneously, by limiting the energy storage spring 142 with the limiting component 150, power loss and vibration caused by structural deformation or transmission clearance can be reduced, ensuring the coordinated operation of the energy storage spring 142, the mounting component 141, and the output shaft 110. Furthermore, the gear meshing transmission enables stable torque transmission, ensuring the precise position of the limiting component 150 during the compression and release of the energy storage spring 142, effectively limiting the energy storage spring 142, thereby ensuring the complete release of energy from the energy storage spring 142 and the stability of the output shaft 110's rotation. Therefore, this embodiment further enhances the reliability and durability of the disconnecting switch operating mechanism during rapid operation, improving the stability and operational efficiency of the disconnecting switch's on / off action.

[0039] In some embodiments, such as Figure 1As shown, the operating mechanism of the disconnecting switch includes multiple limiting members 150. Energy storage springs 142 are correspondingly matched with each limiting member 150, and adjacent limiting members 150 are staggered along the axial direction of the output shaft 110. The operating mechanism of the disconnecting switch can include multiple energy storage springs 142; therefore, the operating mechanism of the disconnecting switch can also be provided with multiple limiting members 150, so that each energy storage spring 142 is respectively installed in the positioning groove 151 of a limiting member 150, thereby ensuring that each energy storage spring 142 has higher transmission reliability under the limiting action of the limiting member 150. Since one end of the limiting member 150 has a transmission sector tooth 152, the transmission sector tooth 152 can be used to mesh with the external gear 131, thereby realizing the transmission between the limiting member 150 and the transmission member 130. The larger central angle corresponding to the transmission sector tooth 152 results in a larger width for the transmission sector tooth 152, which may cause interference between adjacent transmission sector teeth 152, leading to jamming of the operating mechanism of the disconnecting switch and affecting its operation. Therefore, adjacent limiting members 150 can be staggered along the axial direction of the output shaft 110 to avoid interference between the transmission sector teeth 152 of adjacent limiting members 150. The thickness of the transmission sector tooth 152 can be less than the tooth thickness of the external gear 131. Specifically, the thickness of the transmission sector tooth 152 can be less than or equal to half the tooth thickness of the external gear 131. This ensures that the transmission sector teeth 152 of adjacent limiting members 150 do not interfere with each other, while also ensuring a tight meshing connection between the transmission sector teeth 152 of each limiting member 150 and the external gear 131, effectively improving the stability of the transmission connection between the limiting members 150 and the external gear 131. Specifically, as shown in the figure... Figure 1 As shown, the operating mechanism of the disconnect switch may include four energy storage springs 142, and a limiting member 150 is provided for each energy storage spring 142. The central angle of the transmission sector teeth 152 of each limiting member 150 may be less than or equal to 90°. In order to avoid interference between the transmission sector teeth 152 of adjacent limiting members 150 and to ensure the safety of the transmission sector teeth 152 of each limiting member 150, the adjacent transmission sector teeth 152 may be staggered in the axial direction of the output shaft 110, so that the transmission sector teeth 152 of the four limiting members 150 can mesh with the external gear 131 respectively, and the transmission sector teeth 152 of the four limiting members 150 do not interfere with each other, thus providing higher safety.

[0040] According to this embodiment, by providing multiple limiting members 150 for the operating mechanism of the disconnecting switch, and by having each energy storage spring 142 cooperate with the corresponding limiting member 150 and be installed in the positioning groove 151, it can be ensured that each energy storage spring 142 is precisely constrained by the limiting member 150 during energy storage and release, thereby improving the transmission reliability and stability of the energy storage spring 142 during compression and release. Adjacent limiting members 150 are arranged staggered along the output shaft 110 axially, which can effectively avoid interference problems that may occur when the distal transmission sector gear 152 of the limiting member 150 meshes with the external gear 131, thereby preventing the operating mechanism from jamming or being obstructed in rotation, and ensuring a smooth and continuous operation of the disconnecting switch. Therefore, this embodiment effectively improves the transmission safety and mechanical reliability of the operating mechanism, further enhancing the stability, response speed, and long-term durability of the disconnecting switch's on / off action.

[0041] In some embodiments, such as Figure 9 As shown, the input shaft 120 is formed with a bevel gear 121, as... Figure 10 The transmission component 130 shown has an internal gear 132 that meshes with the bevel gear 121 of the input shaft 120. The internal gear 132 has a smaller diameter than its external gear 131, ensuring reliable meshing while allowing space for the limiting member 150 to mesh with the sector gear 152 and the external gear 131. The internal gear 132 meshes with the bevel gear 121 of the input shaft 120. The input shaft 120 has a bevel gear 121 at one end near the transmission component 130, which meshes with the internal gear 132. The axial direction of the transmission component 130 forms a right angle with the extension direction of the input shaft 120, creating a right-angle transmission mechanism between the transmission component 130 and the input shaft 120. This effectively saves space occupied by the operating mechanism. The bevel gear 121 on the input shaft 120 meshes with the internal gear 132 of the transmission component 130. Simultaneously, as the input shaft 120 rotates, the meshing of the bevel gear 121 and internal gear 132 enables transmission, driving the transmission component 130 to rotate. This, in turn, drives the output shaft 110 connected to it to rotate, causing the energy storage component 140 and the limiting component 150 to rotate synchronously. The energy storage component 140 stores energy and releases it to the output shaft 110, driving the output shaft 110 to rotate rapidly, thus achieving rapid on / off switching of the disconnector. Specifically, based on the structure of the disconnector, the input shaft 120 of its operating mechanism does not need to achieve a full rotation; it only needs to be able to oscillate back and forth within a certain range to achieve on / off control of the disconnector. Therefore, the central angle corresponding to the toothed portion of the bevel gear 121 can be less than or equal to 120°, and the central angle corresponding to the toothed portion of the meshing internal gear 132 can also be less than or equal to 120°.

[0042] According to the disconnector operating mechanism provided in this embodiment, a right-angle transmission structure is formed between the input shaft 120 and the transmission member 130 by setting a bevel gear 121 on the input shaft 120 and an internal gear 132 meshing with it on the transmission member 130. On the one hand, the transmission method of the bevel gear 121 meshing with the internal gear 132 can reliably transmit the driving force to the transmission member 130 when the input shaft 120 rotates or swings, thereby stably driving the transmission member 130 to rotate; on the other hand, since the diameter of the internal gear 132 of the transmission member 130 is smaller than the diameter of the external gear 131, sufficient space is reserved on the periphery of the external gear 131 for meshing with the transmission sector gear 152 of the limiting member 150, thereby achieving reliable driving of the energy storage spring 142 and the limiting member 150 simultaneously without increasing the size of the mechanism. This embodiment can achieve efficient and stable power transmission within a limited space, enabling the energy storage component 140, the limiting component 150, and the output shaft 110 to respond synchronously to input actions, accelerating the energy storage and release process of the disconnecting switch, and improving the speed, stability, and reliability of the disconnecting switch's on / off action.

[0043] In some embodiments, under the drive of the transmission member 130, the rotation angle of the output shaft 110 is greater than the rotation angle of the limiting member 150. Since the input shaft 120 is connected to the transmission member 130, and the output shaft 110 is coaxially connected to the transmission member 130, the output shaft 110 and the transmission member 130 can rotate synchronously. Because the bevel gear 121 of the input shaft 120 meshes with the internal gear 132 of the transmission member 130, the input shaft 120 can drive the transmission member 130 to rotate, allowing the rotation angle of the transmission member 130 to be greater than the rotation angle of the input shaft 120. Since the output shaft 110 and the transmission member 130 can rotate synchronously, their rotation angles can be equal. Because the external gear 131 of the transmission member 130 has a large number of teeth and a large diameter, the meshing connection between the external gear 131 and the transmission sector gear 152 of the limiting member 150 allows the angle through which the limiting member 150 rotates to be less than the rotation angle of the transmission member 130. Therefore, the output shaft 110 can rotate at an angle greater than the limit member 150.

[0044] According to this embodiment, the transmission member 130 can be coaxially connected to the output shaft 110, enabling the transmission member 130 and the output shaft 110 to rotate synchronously with the same rotation angle. Based on the difference in gear diameter and number of teeth between the internal gear 132 and the external gear 131 of the transmission member 130, and because the internal gear 132 of the transmission member 130 meshes with the bevel gear 121 of the input shaft 120, the transmission member 130 can have a larger rotation angle than the input shaft 120. Therefore, the rotation angle of the output shaft 110 is also greater than that of the input shaft 120. Thus, rapid energy storage and release can be achieved even when the rotation angle of the input shaft 120 is relatively small. This makes the manually input controlled isolating switch operating mechanism provided in this disclosure more labor-saving and easier for users to operate. Since the external gear 131 meshes with the transmission sector gear 152 of the limiting member 150, the rotation angle of the limiting member 150 is less than the rotation angle of the transmission member 130, thereby ensuring that the rotation angle of the limiting member 150 is less than the rotation angle of the output shaft 110. As a result, the limiting member 150 can have a better limiting effect on the energy storage spring 142, avoiding overstretching or lateral displacement of the energy storage spring 142, effectively preventing the failure of the energy storage spring 142, and improving the operational stability and safety of the disconnecting switch's operating mechanism.

[0045] In some embodiments, the operating mechanism of the disconnecting switch includes: a first input port, formed in the shape of a square groove on the top of the input shaft 120; a second input port, formed in the shape of a square groove on the surface of the transmission member 130; and an output shaft 110 having a protruding cross-shaped structure at one end for connecting with the moving contact of the disconnecting switch. The top of the input shaft 120 may have a square groove as the first input port, and the transmission member 130 may have a second input port. The first and second input ports may have the same shape and size. An input member may be provided, adapted to the first and second input ports, with one end of the input member forming a mounting block, allowing the mounting block to be installed in the first or second input port. The other end of the input member may be a handle, allowing the user to manually rotate the handle to rotate the input shaft 120 or the transmission member 130, thereby controlling the start and stop of the disconnecting switch's operating mechanism. The other end of the input member may also be connected to a drive member, allowing the user to drive the input shaft 120 or the transmission member 130 to rotate, thereby controlling the start and stop of the disconnecting switch's operating mechanism. The end of the output shaft 110 furthest from the transmission member 130 may have a protruding cross-shaped structure for connecting with the moving contact of the disconnecting switch. This connection between the output shaft 110 and the moving contact via the outwardly protruding cross-shaped structure at the end of the output shaft 110 enhances stability and improves the operational stability and safety of the disconnecting switch's operating mechanism. Furthermore, the overall cross-shaped structure of the output shaft 110 ensures a secure connection with the transmission member 130, guaranteeing transmission stability.

[0046] In some embodiments, the input shaft 120 rotates at least 90°, and the rotation of the transmission member 130 and the output shaft 110 drives the moving contact of the disconnecting switch to rotate by an angle greater than or equal to 100° and less than or equal to 145°, while the rotation angle of the limiting member is an acute angle. Specifically, the rotation angle of the input shaft 120 can be greater than or equal to 90°. In some examples, the rotation angle of the input shaft 120 can be 92°, or less than or equal to 95°. The rotation of the input shaft 120 can drive the rotation of the transmission member 130, and the rotation angle of the transmission member 130 and the output shaft 110 can be greater than the rotation angle of the input shaft, thus achieving angular displacement amplification transmission from the input shaft 120 to the output shaft 110. Specifically, when the input shaft 120 rotates 90°, it can drive the transmission member 130 to rotate 100° to 145°. Since the input shaft 120 meshes with the internal gear of the transmission component 130, the transmission ratio between the bevel gear of the input shaft 120 and the internal gear of the transmission component 130 can be designed to achieve a 90° rotation of the input shaft 120 and a rotation angle of the transmission component greater than or equal to 100° and less than or equal to 145°. During rotation, the transmission component 130 can drive the output shaft 110 and the limiting component 150 to rotate through its coaxial connection with the output shaft 110. The rotation of the external gear of the transmission component 130 causes the transmission sector gear 152, which meshes with the external gear, to move accordingly, thereby causing the limiting component 150 to rotate, resulting in an acute angle for the limiting component 150. Specifically, when the input shaft rotates 90°, the limiting component 150 can be driven to rotate 60° around its fixed axis through the transmission component. Since the fixed axis of the limiting component and the fixed axis of the energy storage spring are coaxially arranged, the energy storage spring 142 is compressed as the limiting component 150 rotates, and its compression speed is proportional to the rotation angle of the limiting component 150. Therefore, by driving the limiting member 150 to rotate through the transmission member 130, the compression efficiency of the energy storage spring 142 can be significantly improved.

[0047] Therefore, the energy storage spring 142 can reach near its maximum compression within a shorter input rotation range, enabling the energy storage component 140 to complete the energy storage process in a shorter time. Once the energy storage spring 142 reaches the set compression, it enters the energy release phase. Due to the large reverse return angle of the limiting member 150, the energy released by the energy storage spring 142 can be more fully converted into driving torque on the output shaft 110, giving the output shaft 110 a higher initial acceleration. Thus, at the instant the disconnector performs closing or opening actions, the output shaft 110 can achieve rapid and stable rotation, improving the response speed and operational reliability of the entire operating mechanism.

[0048] Furthermore, this embodiment reduces the torque required to overcome. For disconnecting switch devices using handles or other manual input methods, significant compression of the energy storage spring 142 can be achieved within a limited stroke of 90° rotation of the input shaft 120, eliminating the need for large-angle rotation by the user to complete the energy storage process. Both the transmission component 130 and the output shaft 110 can rotate at angles greater than or equal to 100° and less than or equal to 145°, allowing a smaller rotation of the input shaft 120 to drive a larger rotation angle in the transmission component 130 and the output shaft 110. This further enhances the labor-saving and convenience of the disconnecting switch operating mechanism in manual operation scenarios, making it particularly suitable for applications with limited space, frequent operations, or requiring rapid response.

[0049] In some embodiments, the rotation angle of the transmission member 130 can be smaller than the rotation angle of the output shaft 110. There is a free-spinning stroke in the rotational connection between the transmission member 130 and the output shaft 110. Therefore, in some examples, when the input shaft 120 rotates approximately 90°, the transmission member 130 can rotate approximately 110°. Due to the free-spinning stroke in the rotational connection between the transmission member 130 and the output shaft 110, the rotation angle of the output shaft 110 can be greater than that of the transmission member 130, and thus greater than 110°. Specifically, in some examples, a 90° rotation of the input shaft 120 can drive the transmission member to rotate 110°, while the rotation angle of the output shaft 110 can be 120°, or greater than 120°. Thus, even with a limited rotation angle of the input shaft 120, the output shaft 110 can have a larger rotation angle, thereby ensuring a high response efficiency of the disconnecting switch. The free-spinning stroke between the output shaft 110 and the transmission member 130 can further improve the response speed and operational reliability of the disconnecting switch. The idle stroke between the transmission component 130 and the output shaft 110 can effectively reduce transmission shock and structural fatigue, avoid failures and aging caused by large transmission force values, improve the reliability and stability of the energy storage components and the overall operating mechanism, and extend the service life of the disconnecting switch.

[0050] In some embodiments, such as Figure 10As shown, the transmission component 130 may include an internal gear 132 and an external gear 131. The internal gear 132 is connected to the input shaft 120, and the external gear 131 is connected to the limiting member 150. The gear ratio between the internal gear 132 and the external gear 131 is 1:3. In some embodiments, the transmission component 130 may include an internal gear 132 and an external gear 131, which are coaxially arranged. The internal gear 132 and the external gear 131 may also be an integrated component. Specifically, the transmission component 130 may include an internal gear 132 disposed on one side of the input shaft 120. The internal gear 132 may be a sector gear structure for meshing with the drive unit on the input shaft 120, so that the rotation of the input shaft 120 can directly drive the internal gear 132 to rotate. The transmission component 130 may also include a coaxially arranged external gear 131, with the internal gear 132 and the external gear 131 fixedly connected and rotating synchronously. Since the gear ratio of the internal gear 132 to the external gear 131 is set to 1:3, when the input shaft 120 drives the transmission component 130 through the internal gear 132, each unit angle rotation of the internal gear 132 will cause the external gear 131 to obtain a 3 times angular displacement through gear ratio conversion. Therefore, the external gear 131 can produce a significant rotation angle amplification effect at a small input angle, enabling it to drive the transmission sector teeth 152 on the limiting component 150 with a larger angular displacement. Thus, when the input shaft 120 drives the internal gear 132 to rotate, the internal gear 132 drives the external gear 131 to produce a larger angle of rotation at a smaller angle; and the external gear 131 further causes the limiting component 150 to rotate around its fixed axis through the transmission sector teeth 152 meshing with the limiting component 150. The rotation of the limiting component 150 causes the energy storage spring 142 to compress rapidly, allowing it to reach near-maximum compression within a short input rotation stroke.

[0051] The 1:3 gear ratio design of the internal and external gears significantly amplifies the rotation angle of the limiting member 150, further ensuring the rapid compression of the energy storage spring 142. The energy storage process is greatly accelerated, and the energy storage spring 142 can be compressed to the preset energy storage state in a shorter time. When the energy storage spring 142 releases energy, it obtains a higher initial reverse angular velocity. The external gear 131 is driven by the return stroke of the limiting member 150, which enables the output shaft 110 to obtain higher torque and acceleration. This improves the rapid switching capability of the disconnecting switch, making the entire operating mechanism respond more quickly and stably at the moment of contact action. The input shaft 120 is easier to operate, as only a small input angle is required to complete energy storage, making it suitable for manually input disconnecting switch structures.

[0052] Through the cooperation of the internal gear 132 and the external gear 131, the transmission component 130 can provide a large output angle driving capability with a small input angle, making the movement of the limit component 150 and the energy storage spring 142 more sensitive and the compression speed faster, thereby further improving the operating speed and reliability of the disconnect switch operating mechanism.

[0053] Based on the same inventive concept, such as Figure 11 As shown, this disclosure also provides a disconnecting switch, which may include: an operating mechanism of the disconnecting switch as described in any of the foregoing embodiments, a housing 210, and a switch body.

[0054] The operating mechanism, driven manually or electrically by the input shaft 120, compresses the energy storage spring 142 via the transmission component 130 to store mechanical energy. After energy storage, the transmission mechanism's motion causes the energy storage spring 142 to rapidly release its elastic potential energy, providing a large instantaneous driving torque to the output shaft 110, causing it to rotate rapidly and thus enabling the disconnecting switch to quickly switch on and off. The limiting component 150 positions, limits, and supports the energy storage spring 142, ensuring its stable operation during high-force compression and rapid energy release. The limiting component 150 employs a rigid structure and meshes with the external gear 131, improving the rigidity and stability of the transmission process and preventing the energy storage spring 142 from shifting, deforming, or failing under high loads. Furthermore, the staggered arrangement of multiple limiting components 150 avoids mutual interference, further enhancing the overall stability and safety of the operating mechanism. By making the angle at which the transmission component 130 drives the output shaft 110 smaller than the angle at which it drives the limiting component 150, energy storage can be achieved quickly with smaller input movements, shortening the time it takes for the energy storage spring 142 to reach its maximum compression, and giving the energy storage component 140 a faster response speed. Simultaneously, this angle optimization significantly reduces the torque required for operating the input shaft 120, improving the convenience of manual operation and making the disconnecting switch more labor-saving and efficient in field operation. By setting multiple energy storage springs 142 and multiple limiting components 150, the operating mechanism has higher transmission redundancy, more uniform force distribution, and more reliable mechanical support capabilities, further improving the service life and operational reliability of the energy storage component 140 and the entire disconnecting switch.

[0055] The outer casing 210 covers the outside of the operating mechanism of the disconnect switch. The outer casing 210 can cover the outside of the operating mechanism to protect it. The outer casing 210 can be cuboid in shape. Four energy storage spring fixing shafts can be respectively provided at the four corners of one side of the inner cavity of the outer casing 210. The energy storage spring fixing shafts can be hinged to the energy storage spring 142 of the operating mechanism, allowing the energy storage spring 142 to be positioned diagonally on the inner cavity of the outer casing 210 and to rotate to a certain extent with rotation. By hinged to the outer casing 210, the installation of the energy storage spring 142 is facilitated, enabling faster and simpler installation and positioning during the installation of the operating mechanism. The outer casing 210 can cover the outside of the operating mechanism to protect it. The four corners of one side of the inner cavity of the outer casing 210 can also be respectively provided with limiting member fixing shafts coaxially arranged with the energy storage spring fixing shaft, so that the limiting member 150 is hinged to the limiting member fixing shaft. This allows the energy storage spring 142 and the limiting member 150 to rotate coaxially and in the same direction, thereby better realizing the supporting and limiting function of the limiting member 150 on the energy storage spring 142. Furthermore, as... Figure 11 As shown, the housing 210 may also have a mounting structure for mounting the input shaft 120, so that the side of the input shaft 120 used for connecting with the external drive device can be exposed, so as to facilitate the connection between the input shaft 120 and the external drive device.

[0056] The switch body may include a moving contact assembly, which is connected to the output shaft of the operating mechanism and rotates synchronously with the output shaft. The switch body may also include a stationary contact assembly; the connection and separation of the stationary and moving contact assemblies enable the opening and closing of the disconnecting switch. One end of the moving contact assembly can be connected to the output shaft 110, allowing the moving contact assembly to rotate with the output shaft. Rotation of the output shaft 110 causes the moving contact assembly to rotate accordingly, thereby changing the moving and stationary contact assemblies from a separated state to a connected state to connect the disconnecting switch, or vice versa, to disconnect the disconnecting switch.
