[0002] As a key device for achieving electrical isolation in power systems, the operational reliability and structural compactness of disconnecting switches largely depend on the design of their internal transmission mechanisms.
[0003] Currently, most disconnect switches have problems such as a large number of parts, complex moving parts, and high assembly precision requirements. The complex transmission path not only leads to greater energy loss during transmission, affecting the ease of operation, but also occupies a lot of internal space in the housing, limiting the installation layout of other functional modules. Summary of the Invention
[0004] This invention provides a disconnecting switch with a simple structure, short transmission path, low energy loss and small space occupation, which can significantly improve the overall compactness and operation efficiency while ensuring high reliability of opening and closing performance.
[0005] The embodiments of the present invention can be implemented as follows: In a first aspect, the present invention provides an isolating switch, comprising: An operating mechanism, wherein the operating mechanism is provided with an output component, the output component being used for movement under manual and / or electric operation; A contact mechanism, comprising a moving contact, a stationary contact, and a contact base, wherein the moving contact is disposed on the contact base; A drive shaft is rotatably and axially movable on the contact seat. The drive shaft is connected to the output component and is used to rotate under the drive of the output component to drive the contact seat to move axially relative to the drive shaft, so as to drive the moving contact to close or open with the stationary contact.
[0006] In an optional embodiment, the outer wall of the drive shaft is provided with a first sliding portion, which extends spirally along the axial direction of the drive shaft. The contact seat is provided with a mounting hole, and the inner wall of the mounting hole is provided with a second sliding portion. The first sliding portion and the second sliding portion slide in cooperation.
[0007] In an optional embodiment, one of the first sliding portion and the second sliding portion is a groove, and the other is a protruding structure.
[0008] In an optional embodiment, the protruding structure is provided with a rolling element that rolls in cooperation with the groove.
[0009] In an optional embodiment, the protruding structure is integrally formed with the drive shaft or the mounting hole.
[0010] In an optional embodiment, the outer wall of the drive shaft is provided with a plurality of first sliding portions, and the inner wall of the mounting hole is provided with a plurality of second sliding portions, wherein the plurality of first sliding portions and the plurality of second sliding portions are provided in a one-to-one correspondence.
[0011] In an optional embodiment, the disconnecting switch further includes a first transmission wheel, a transmission rod, and a second transmission wheel that are movably connected in sequence. The first transmission wheel is fixedly engaged with the output component, and the second transmission wheel is fixedly engaged with the transmission shaft. The output component is used to drive the first transmission wheel, the transmission rod, and the second transmission wheel to move, so as to drive the transmission shaft to rotate through the second transmission wheel.
[0012] In an optional embodiment, the contact mechanism further includes a mounting member, the stationary contact being disposed on the mounting member, and the contact seat being slidably disposed on the mounting member.
[0013] In an optional embodiment, there are multiple moving contacts and multiple stationary contacts. The multiple moving contacts are all disposed on the contact base. The contact base is used to drive the multiple moving contacts to move synchronously, so that the multiple moving contacts correspond one-to-one with the multiple stationary contacts to close or open the circuit. The moving contact includes a first contact, a second contact, and an elastic element. The first contact and the second contact are connected in parallel. The end of the elastic element is provided with two abutting portions, which abut against the first contact and the second contact, respectively.
[0014] In an optional embodiment, the operating mechanism further includes a first energy storage component, an energy storage handle, a closing input component, an opening input component, and a trip unit. The first energy storage component is directly or indirectly connected to the output component. The energy storage handle is connected to the first energy storage component. The closing input component is connected to the first energy storage component. The opening input component is connected to the output component. The energy storage handle is used to drive the first energy storage device to store energy, and simultaneously drive the closing input device and the opening input device to engage; the closing input device is used to be driven to trip, so as to drive the first energy storage device to release energy and drive the output device to move, so as to drive the moving contact to close with the stationary contact; the trip unit is connected to the opening input device, and is used to drive the opening input device to trip when a trip signal is received, so as to open the moving contact with the stationary contact.
[0015] The beneficial effects of the disconnecting switch provided in this embodiment of the invention include: when the output component is driven to rotate and drives the transmission shaft to rotate, the transmission shaft rotates relative to the contact seat while simultaneously displacing axially relative to the contact seat, thereby causing the contact seat to displace in a predetermined direction; since the moving contact and the contact seat remain relatively fixed, the displacement of the contact seat directly drives the moving contact to move synchronously, ultimately realizing the closing or opening of the circuit between the moving contact and the stationary contact; it can be seen that the disconnecting switch provided in this embodiment has a simple structure, short transmission path, low energy loss and small space occupation, and can significantly improve the overall compactness and operating efficiency while ensuring high reliability of opening and closing performance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.
[0025] As a key device for achieving electrical isolation in power systems, the operational reliability and structural compactness of disconnecting switches largely depend on the design of their internal transmission mechanisms.
[0026] Currently, most disconnect switches have problems such as a large number of parts, complex moving parts, and high assembly precision requirements. The complex transmission path not only leads to greater energy loss during transmission, affecting the ease of operation, but also occupies a lot of internal space in the housing, limiting the installation layout of other functional modules.
[0027] Therefore, there is an urgent need for a new type of disconnector transmission mechanism that is simplified in structure, has a short transmission path, low energy loss and small space occupation, so as to significantly improve the overall compactness and operating efficiency while ensuring high reliability of opening and closing performance.
[0028] Please see Figures 1 to 8 This invention provides a disconnecting switch 10, which includes an operating mechanism 100, a contact mechanism 200, and a transmission assembly 300.
[0029] The operating mechanism 100 is provided with an output component 110, which can rotate under the drive of at least one of manual operation (e.g., handle or button) and electric operation (e.g., triggered by shunt trip unit 160) to achieve manual control or remote control, thereby improving the adaptability of the disconnector switch 10. It is worth mentioning that the output component 110 is not directly connected to the contact head, but the motion mode is converted through the transmission component 300.
[0030] Specifically, the contact mechanism 200 includes a moving contact 210, a stationary contact 220, and a contact seat 230. The moving contact 210 is disposed in the contact seat 230. The transmission assembly 300 includes a transmission shaft 310, which is rotatably and axially movable in the contact seat 230. The transmission shaft 310 is connected to the output component 110 and is used to rotate under the drive of the output component 110 to drive the contact seat 210 to move axially relative to the transmission shaft 310, thereby driving the moving contact 210 to close or open with the stationary contact 220.
[0031] Therefore, when the output component 110 is driven to rotate and drives the transmission shaft 310 to rotate, the transmission shaft 310 rotates relative to the contact seat 230 while displacing axially relative to the contact seat 230, thereby causing the contact seat 210 to move in a predetermined direction (such as the horizontal direction). Since the moving contact 210 and the contact seat 230 remain relatively fixed, the displacement of the contact seat 230 directly drives the moving contact 210 to move synchronously, ultimately achieving contact (closing) or separation (opening) between the moving contact 210 and the stationary contact 220.
[0032] As can be seen, the disconnector 10 provided in this embodiment has a simple structure, short transmission path, low energy loss and small space occupation, and can significantly improve the overall compactness and operation efficiency while ensuring high reliability of opening and closing performance.
[0033] Furthermore, the outer wall of the drive shaft 310 is provided with a first sliding part 311, which extends spirally along the axial direction of the drive shaft 310. The contact seat 230 is provided with a mounting hole 231, and the inner wall of the mounting hole 231 is provided with a second sliding part 232. The first sliding part 311 and the second sliding part 232 are slidably engaged.
[0034] Therefore, the drive shaft 310 is driven to rotate by the output component 110. Due to the helical meshing constraint between the first sliding part 311 and the second sliding part 232, the drive shaft 310 itself cannot rotate freely in the mounting hole 231 without axial movement. That is, each rotation of the drive shaft 310 will push the contact 210 seat to produce a quantitative displacement corresponding to the helical lead along the axial direction of the drive shaft 310.
[0035] It is understandable that the direction of displacement depends on the direction of the helical rotation (left-hand or right-hand) and the direction of rotation, which in turn determines whether the moving contact 210 moves toward the stationary contact 220 (closing) or moves away from the stationary contact 220 (opening).
[0036] Specifically, one of the first sliding part 311 and the second sliding part 232 is a groove, and the other is a protruding structure.
[0037] In this embodiment, a groove refers to a recessed structure extending along a spiral direction. Its cross-section can be a common shaped contour such as U-shape, V-shape, rectangle or arc, and it has a definite depth, width and sidewall inclination angle. A protruding structure refers to a matching raised structure, such as a strip-shaped rib, a prismatic boss or an annular protrusion, etc. Its outer contour is adapted to the inner contour of the groove, so that the two can form a sliding constraint relationship of surface contact or line contact in the assembled state.
[0038] In practical applications, when the drive shaft 310 rotates, the protruding structure is restricted to move within the guide path of the groove, thus strictly converting the rotational motion into axial displacement along the helical angle of the groove. At this time, the protruding structure and the groove achieve force transmission and motion guidance through sliding friction. This sliding friction provides the necessary positive pressure to maintain the stability of the fit and allows the relative motion to continue without jamming.
[0039] Furthermore, the transmission assembly 300 also includes a rolling element 320, which is provided on the protruding structure and rolls with the groove.
[0040] In this embodiment, the protruding structure integrates at least one freely rotatable rolling element 320. The rolling element 320 can be a spherical metal rolling body (e.g., a stainless steel ball), whose diameter is adapted to the cross-sectional dimensions of the groove, allowing it to be embedded inside the groove and roll along a helical trajectory therein. The ball is typically constrained within a pre-set recess, cage, or annular groove on the protruding structure, ensuring reliable positioning in the radial direction while possessing sufficient degrees of freedom for rotation and revolution in the axial and circumferential directions.
[0041] When the drive shaft 310 rotates, the protruding structure rotates synchronously with the shaft, and the rolling element 320 on it rolls continuously between the walls of the groove, rather than sliding along the surface of the groove as a whole.
[0042] Therefore, the rolling contact between the rolling element 320 and the groove significantly reduces the driving torque required for relative motion: on the one hand, the rolling friction coefficient is much lower than the sliding friction coefficient, so that in scenarios such as remote tripping that require small force to trigger, the shunt trip unit 160 only needs to provide a small impact to effectively start the tripping action; on the other hand, the rolling contact reduces local stress concentration and material wear in the contact area, which is conducive to maintaining the stability of the spiral guide accuracy during long-term operation.
[0043] It is worth mentioning that the protruding structure is integrally formed with the drive shaft 310 or the mounting hole 231, which not only simplifies the assembly process and reduces the number of parts and the risk of failure, but also ensures that the protruding structure is not easy to loosen, deform or break under high loads (such as the electrodynamic impact during a high current short circuit), thereby ensuring the long-term reliability of the helical guide motion.
[0044] In addition, the outer wall of the drive shaft 310 is provided with a plurality of first sliding parts 311, and the inner wall of the mounting hole 231 is provided with a plurality of second sliding parts 232, with the plurality of first sliding parts 311 and the plurality of second sliding parts 232 being provided in a one-to-one correspondence.
[0045] Specifically, the multiple first sliding parts 311 are several independent spiral extension structures that are evenly or symmetrically distributed along the circumference of the outer wall of the transmission shaft 310, such as three, four or six grooves (or ribs) that extend spirally along the axial direction, each with the same helix angle, lead and cross-sectional profile.
[0046] Accordingly, multiple second sliding portions 232 are machined on the inner circumferential surface of the mounting hole 231 of the contact seat 230, corresponding to the position of each first sliding portion 311, with an equal number of second sliding portions 232 and matching geometric parameters. If the first sliding portion 311 is a groove, then the second sliding portions 232 are equally spaced spiral ribs; and vice versa. Each first sliding portion 311 forms a sliding fit with only one second sliding portion 232, and they do not intersect, overlap, or share the same contact area.
[0047] When the drive shaft 310 is driven to rotate by the output component 110, all pairs of first sliding parts 311 and second sliding parts 232 slide relative to each other synchronously, and jointly bear the axial thrust and radial reaction force generated by the opening and closing action of the contact system.
[0048] In this way, on the one hand, the concentrated load of single-point contact is distributed to multiple helical pairs, which significantly reduces the contact stress per unit area and delays groove wear and protrusion plastic deformation; on the other hand, the multiple helical pairs form symmetrical constraints in the circumferential direction, which effectively suppresses the slight swaying, tilting or torsional instability of the drive shaft 310 during rotation, thereby ensuring the straightness and stability of the axial movement of the contact seat 230. Especially in the high-current disconnecting switch 10, where the contact pressure is high and the arc extinguishing impact is strong, this multi-point guiding structure can prevent problems such as contact skew, seizing or asynchronous breaking caused by local guiding failure.
[0049] Furthermore, the transmission assembly 300 also includes a first transmission wheel 330, a transmission rod 340, and a second transmission wheel 350 that are movably connected in sequence. The first transmission wheel 330 is fixedly engaged with the output component 110, and the second transmission wheel 350 is fixedly engaged with the transmission shaft 310. The output component 110 is used to drive the first transmission wheel 330, the transmission rod 340, and the second transmission wheel 350 to move, so as to drive the transmission shaft 310 to rotate through the second transmission wheel 350.
[0050] In practical applications, when the output component 110 is rotated manually or electrically, the first transmission wheel 330 rotates accordingly, thereby pushing the transmission rod 340, which is hinged to it, to swing. This swinging motion is transmitted to the second transmission wheel 350 and converted into rotational motion of the second transmission wheel 350 around its central axis. Since the second transmission wheel 350 is fixedly engaged with the transmission shaft 310, this rotational motion directly drives the transmission shaft 310 to rotate. The entire process does not require gear meshing or belt tensioning; it relies solely on the geometric constraints of the rigid rod and the rotational freedom of the hinge point to complete the power transmission, resulting in a simple structure and rapid response.
[0051] Furthermore, the contact mechanism 200 also includes a mounting component 240, with the stationary contact 220 disposed on the mounting component 240 and the contact seat 230 slidably disposed on the mounting component 240, so that the installation position of the stationary contact 220 is absolutely fixed and the movement trajectory of the contact seat 230 is strictly limited, thereby ensuring that the moving contact 210 can accurately align with the center area of the stationary contact 220 each time the circuit is closed, forming a stable, low-resistance, and uniform contact surface; while during the opening, the contact seat 230 reliably retracts along the guide path under the drive of the transmission component 300, ensuring sufficient electrical clearance.
[0052] It should also be noted that there are multiple moving contacts 210 and multiple stationary contacts 220. Multiple moving contacts 210 are all set in contact base 230. Contact base 230 is used to drive multiple moving contacts 210 to move synchronously, so that multiple moving contacts 210 correspond one-to-one with multiple stationary contacts 220 to close or open the circuit.
[0053] In detail, such as Figure 3 As shown, the moving contact 210 includes a first contact 211, a second contact 212, and an elastic element. The first contact 211 and the second contact 212 are arranged in parallel, and the first contact 211 is stepped. The second contact 212 is disposed at the stepped structure of the first contact 211, and the walls of the first contact 211 and the second contact 212 are flush.
[0054] The elastic element is disposed on one side of the first contact 211 and the second contact 212. The end of the elastic element is provided with two abutting parts, which abut against the first contact 211 and the second contact 212 respectively.
[0055] In addition, the first contact 211 is also provided with an arc-starting angle 213.
[0056] Furthermore, the operating mechanism 100 also includes a first energy storage component 120, an energy storage handle 130, a closing input component 140, a opening input component 150, and a trip unit 160. The first energy storage component 120 is directly or indirectly connected to the output component 110. The energy storage handle 130 is connected to the first energy storage component 120. The closing input component 140 is connected to the first energy storage component 120. The opening input component 150 is connected to the output component 110.
[0057] The energy storage handle 130 is used to drive the first energy storage component 120 to store energy, and simultaneously drive the closing input component 140 and the opening input component 150 to engage. The closing input component 140 is used to be driven to trip, so as to drive the first energy storage component 120 to release energy and drive the output component 110 to move, so as to drive the moving contact 210 to close with the stationary contact 220. The trip unit 160 is connected to the opening input component 150 and is used to drive the opening input component 150 to trip when a trip signal is received, so as to open the moving contact 210 and the stationary contact 220.
[0058] Therefore, when closing is required, an external signal (such as pressing a button) is applied to the closing input 140 to trip, and the first energy storage device 120 releases energy. The stored energy is amplified through the transmission path and transmitted to the output device 110, driving the output device 110 to rotate. This, in turn, drives the contact 210 to move through the transmission assembly 300, thus closing the moving contact 210 and the stationary contact 220. When opening is required, an external signal (such as pressing a button) is applied to the opening input 150 to trip. Alternatively, the trip unit 160 (e.g., the shunt trip unit 160) can generate electromagnetic force after receiving a remote electrical signal, driving its armature rod to strike or pull the opening input 150, causing it to leave its original locked position, i.e., "trip". At this time, the opening input 150 releases the constraint on the output device 110 or related transmission links, so that the output device 110 rotates in the opposite direction, causing the contact 210 to move in the opposite direction, thus achieving rapid separation of the moving contact 210 and the stationary contact 220.
[0059] In summary, this embodiment of the invention provides a disconnecting switch 10. When the output component 110 is driven to rotate, it drives the transmission shaft 310 to rotate. Subsequently, the transmission shaft 310 rotates relative to the contact seat 230 while simultaneously displacing axially relative to the contact seat 230, thereby causing the contact seat 210 to displace in a predetermined direction (such as the horizontal direction). Since the moving contact 210 and the contact seat 230 remain relatively fixed, the displacement of the contact seat 230 directly drives the moving contact 210 to move synchronously, ultimately achieving contact (closing) or separation (opening) between the moving contact 210 and the stationary contact 220. It can be seen that the disconnecting switch 10 provided in this embodiment has a simple structure, short transmission path, low energy loss, and small space occupation. It can significantly improve the overall compactness and operating efficiency while ensuring high reliability of opening and closing performance.
