Description

Technical Field

[0001] This invention belongs to the field of power equipment technology, and specifically relates to a high-voltage switchgear operating device. Background Technology

[0002] High-voltage disconnect switches are among the most widely used and critical pieces of equipment in power systems. They are responsible for the distribution and isolation of electrical energy. High-voltage disconnect switches are primarily operated via a control device. This device typically consists of an operating mechanism, an angle compensation mechanism, and an operating lever. The operating mechanism is connected to the high-voltage disconnect switch via a shaft head, angle compensation mechanism, and operating lever. The operating lever and the rotating shaft of the high-voltage disconnect switch are connected by a pin, leaving no room for adjustment. Similarly, the output shaft of the operating mechanism is connected to the shaft head, and the shaft head is connected to the angle compensation mechanism via pins, also lacking angle adjustment capability.

[0003] Therefore, the angle compensation mechanism is a very important component. It is used to connect the operating mechanism and the operating lever, and is responsible not only for transmitting torque, but also for adjusting itself to correct for angular deviations between the operating mechanism and the operating lever caused by various errors.

[0004] Existing angle compensation mechanisms typically take the following forms: The first type is a clamp connection, consisting of multiple clamps and a backplate. The clamps bypass the shaft head and operating rod and connect to the backplate, relying on the friction between the clamps and the backplate to transmit torque. This design can compensate for angle deviations and solve the problem of adjusting angle deviations. However, over time, the friction between the clamps and the operating rod decreases, causing relative slippage. This results in the disconnector switch not opening or closing properly, leading to power failure.

[0005] The second method uses two flanges connected together, relying on friction between them to transmit torque. One of the flange connection holes is an elongated hole. This design can compensate for angle deviations and solve the problem of adjusting angle errors. However, over time, the friction between the two flanges decreases, causing relative slippage. This can lead to the disconnector switch not opening or closing properly, resulting in a power failure.

[0006] The third method uses two semi-circular plates clamping together, relying on friction to adjust the switch's open / closed position during installation and adjustment. Then, holes are drilled to secure it with pins. However, many sites lack the conditions for drilling. Furthermore, drilling on-site can damage the rust-proof protective layer of the parts, causing them to rust and fail. Summary of the Invention

[0007] The present invention provides a high-voltage switchgear operating device, which aims to solve the technical problems mentioned in the background art.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a high-voltage switchgear operating device, comprising: The operating mechanism has a shaft head fixedly connected to the end of the output shaft; The operating lever is coaxially mounted on the upper side of the shaft head, and its upper end is used to be fixedly connected to the high-voltage disconnect switch. An angle compensation component is connected to the lower end of the operating lever and the shaft head; the angle compensation component includes: The first connecting seat is fixedly connected to the lower end of the operating lever on its upper side and has a first connecting part on its lower side; The second connecting seat has a second connecting part on its upper side, which is rotatably engaged with the first connecting part; and its lower side is fixedly connected to the shaft head. The first adjusting assembly includes a first adjusting rod, two connecting shafts, and a plurality of first limiting blocks. The first adjusting rod is provided with external threads. The two connecting shafts are both sleeved on the first adjusting rod and rotatably connected to the first connecting seat and the second connecting seat, respectively. At least one of the connecting shafts is slidably engaged with the first adjusting rod. The plurality of first limiting blocks are threadedly engaged with the first adjusting rod and are respectively disposed on both sides of the connecting shaft that is slidably engaged with the first adjusting rod, and abut against the connecting shaft.

[0009] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, the first adjusting component includes two first adjusting rods, which are respectively disposed on the upper side of the first connecting seat and the lower side of the second connecting seat.

[0010] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, there are two first adjustment components, which are symmetrically arranged on both sides of the first connecting portion along the axial direction.

[0011] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, a second adjusting component is further included. The second adjusting component includes a second adjusting rod and a second limiting adjusting component. There are two first adjusting components, which are symmetrically arranged on both sides of the axial direction of the first connecting portion. One of the two first adjusting components is sleeved on the second adjusting rod, wherein one connecting shaft is slidably engaged with the second adjusting rod, and the other connecting shaft is slidably engaged with or fixedly connected to the second adjusting rod. The second limiting adjusting component includes a plurality of second limiting blocks, which are threadedly engaged with the second adjusting rod and respectively disposed on both sides of the connecting shaft that is slidably engaged with the second adjusting rod, and abut against the connecting shaft.

[0012] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, there are two second adjustment components, which are symmetrically arranged on both sides of the first connecting part along the axial direction.

[0013] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, the first connecting part is a convex shaft and the second connecting part is a circular hole, or the first connecting part is a circular hole and the second connecting part is a convex shaft, wherein the convex shaft is rotatably disposed in the circular hole.

[0014] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, a limiting bolt and a limiting plate are further included. The limiting plate is disposed on the side of the circular hole facing away from the convex shaft. The limiting bolt is coaxially disposed with the convex shaft and passes through the limiting plate to be screwed to the convex shaft.

[0015] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, the end of the convex shaft protrudes from the circular hole, and the limiting plate abuts against the end of the convex shaft.

[0016] In one possible implementation of the high-voltage switchgear operating device provided by the present invention, the first connecting seat and the second connecting seat are fixedly connected to the operating rod and the shaft head respectively by pins.

[0017] The beneficial effects of the high-voltage switchgear operating device provided by the present invention are as follows: Compared with the prior art, the high-voltage switchgear operating device provided by the present invention fixes the angle by mechanical locking through the threaded engagement of the first limiting block and the first adjusting rod and the tight locking of the connecting shaft, replacing the frictional force transmission of the prior art. This completely avoids relative sliding caused by frictional force attenuation, thereby preventing power failures caused by incomplete opening and closing of the disconnecting switch. Angle adjustment is achieved by rotating the limiting block, eliminating the need for on-site drilling. This adapts to scenarios where drilling is not possible and avoids damaging the anti-rust protective layer of parts, preventing parts from rusting and failing, and extending the service life of the mechanism. The rotational engagement of the first connecting part and the second connecting part provides the basis for angle adjustment. The threaded structure of the first adjusting component makes the angle adjustment process precise and controllable, and the locking by the limiting block after adjustment ensures the stability of the angle position. This allows the torque output by the operating mechanism to be transmitted to the high-voltage disconnecting switch more stably, meeting the requirements for long-term stable operation of the high-voltage disconnecting switch.

[0026] Please refer to the following: Figures 1 to 6The high-voltage switchgear operating device provided by the present invention will now be described. The high-voltage switchgear operating device includes an operating lever 72, an operating mechanism 73, and an angle compensation component. The end of the output shaft of the operating mechanism 73 is fixedly connected to a shaft head 71. The operating lever 72 is coaxially disposed on the upper side of the shaft head 71, and its upper end is used to be fixedly connected to the high-voltage switch. The angle compensation component is connected to the lower end of the operating lever 72 and the shaft head 71.

[0027] The angle compensation assembly includes a first connecting seat 10, a second connecting seat 20, and a first adjusting assembly. The upper side of the first connecting seat 10 is fixedly connected to the lower end of the operating rod 72, and the lower side is provided with a first connecting part 11. The upper side of the second connecting seat 20 is provided with a second connecting part 21, which is rotatably engaged with the first connecting part 11. The lower side is fixedly connected to the shaft head 71. The first adjusting assembly includes a first adjusting rod 31, two connecting shafts 32, and a plurality of first limiting blocks 33. The first adjusting rod 31 is provided with an external thread. The two connecting shafts 32 are both sleeved on the first adjusting rod 31 and are rotatably connected to the first connecting seat 10 and the second connecting seat 20, respectively. At least one connecting shaft 32 is slidably engaged with the first adjusting rod 31. The plurality of first limiting blocks 33 are threadedly engaged with the first adjusting rod 31 and are respectively provided on both sides of the connecting shaft 32 that is slidably engaged with the first adjusting rod 31, and abut against the connecting shaft 32.

[0028] The distance between the two connecting shafts 32 is adjusted by rotating the first limiting block 33, thereby adjusting the relative angle between the first connecting seat 10 and the second connecting seat 20.

[0029] The operating mechanism 73 is an existing mechanism in existing high-voltage switchgear, which can output torque through the output shaft, thereby driving the operating lever to rotate a certain angle.

[0030] It should be noted that the upper side of the first connecting seat 10 is fixed to the operating rod 72, and the lower side of the first connecting part 11 is rotatably engaged with the upper side of the second connecting part 21 of the second connecting seat 20, providing a basic degree of rotational freedom for angle compensation. In the first adjustment assembly, the first adjusting rod 31 with external threads engages with two connecting shafts 32, which are rotatably connected to the first connecting seat 10 and the second connecting seat 20 respectively. At least one connecting shaft 32 is slidably engaged with the first adjusting rod 31. The position change in the length direction of the adjusting rod is achieved through the sliding engagement, which is then converted into an angle change of the first and second connecting seats 20. At the same time, the first limiting block 33, which is threadedly engaged with the first adjusting rod 31, is used to press against both sides of the slidingly engaged connecting shaft 32 (replacing the frictional force transmission of the prior art, and fixing the adjusted position through the mechanical locking of the threaded limiting block to avoid relative sliding). The entire structure adjusts the position of the connecting shaft 32 by rotating the first limiting block 33, and finally achieves the relative angle adjustment of the first and second connecting seats 20, completely eliminating the dependence on friction and eliminating the need for on-site drilling.

[0031] The beneficial effects of the high-voltage switchgear operating device provided in this embodiment of the invention are as follows: Compared with the prior art, the high-voltage switchgear operating device provided in this embodiment of the invention fixes the angle by mechanical locking through the threaded engagement of the first limiting block 33 and the first adjusting rod 31 and the tight locking of the connecting shaft 32, replacing the frictional force transmission of the prior art, completely avoiding relative sliding caused by frictional force attenuation, and thus preventing power failure caused by the disconnecting switch not being in place; the angle adjustment is achieved by rotating the limiting block, without the need for on-site drilling, which is suitable for scenarios where drilling is not possible, and avoids damaging the anti-rust protective layer of the parts by drilling, preventing the parts from rusting and failing, and extending the service life of the mechanism; the rotational engagement of the first connecting part 11 and the second connecting part 21 provides the basis for angle adjustment, the threaded structure of the first adjusting component makes the angle adjustment process precise and controllable, and after adjustment, it is locked by the limiting block to ensure the stability of the angle position, so that the torque output by the operating mechanism can be transmitted to the high-voltage disconnecting switch more stably, meeting the requirements of long-term stable operation of the high-voltage disconnecting switch.

[0032] like Figure 5 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, the first adjustment component includes two first adjustment rods 31, which are respectively disposed on the upper side of the first connecting seat 10 and the lower side of the second connecting seat 20.

[0033] It should be noted that the symmetrical distribution (vertical alignment) of the two adjusting rods ensures more even force distribution on the first and second connecting seats 20, preventing component wear caused by long-term concentrated force on a single adjusting rod. Simultaneously, it further improves the stability of the structure after angle adjustment, making it less prone to loosening and meeting the requirements of long-term, high-intensity operation of high-voltage power equipment. like Figure 1 , Figure 2 and Figure 5 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, there are two first adjustment components, which are symmetrically arranged on both sides of the first connecting part 11.

[0034] It should be noted that two first adjustment components are provided and symmetrically distributed on both sides of the first connecting part 11 along its axial direction. Combined with the rotational fit structure between the first connecting part 11 and the second connecting part 21 (such as the fit between a convex shaft and a round hole, with its axial direction being the axis of rotation), the two symmetrical adjustment components can adjust the relative rotation angle of the first and second connecting seats 20 from both sides around the axis of rotation (for example, the left adjustment component controls the clockwise angle, and the right adjustment component controls the counterclockwise angle). This symmetrical distribution ensures that the adjustment force is evenly transmitted on both sides of the rotating shaft, avoiding rotational deviation caused by unilateral adjustment; furthermore, the two adjustment components can counterbalance each other, further locking the adjusted angle position and preventing angle deviation caused by external forces (such as equipment vibration). Two first adjustment components are symmetrically distributed on both sides of the first connecting part 11, forming a bidirectional adjustment structure around the axis of rotation. During adjustment, a balanced adjustment force can be applied from both sides to avoid problems such as tilting of the connecting seat and offset of the rotating axis caused by unilateral adjustment, making the angle adjustment process smoother and the adjustment result more accurate.

[0035] The symmetrical adjustment components on both sides can form a "two-way locking" effect. Compared with the single-sided adjustment components, it can more effectively resist the influence of external forces (such as vibration during equipment operation, wind force, etc.) on the angle position, further prevent the angle from deviating after adjustment, ensure that the disconnecting switch is always in the correct open and closed position, and reduce the risk of power failure.

[0036] like Figure 6 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, a second adjusting component is further included. The second adjusting component includes a second adjusting rod 41 and a second limiting adjusting component. There are two first adjusting components, which are symmetrically arranged on both sides of the first connecting part 11. One connecting shaft 32 of the two first adjusting components is sleeved on the second adjusting rod 41, wherein one connecting shaft 32 is slidably engaged with the second adjusting rod 41, and the other connecting shaft 32 is slidably engaged with or fixedly connected to the second adjusting rod 41. The second limiting adjusting component includes a plurality of second limiting blocks 42, which are threadedly engaged with the second adjusting rod 41 and are respectively arranged on both sides of the connecting shaft 32 that is slidably engaged with the second adjusting rod 41, and abut against the connecting shaft 32.

[0037] It should be noted that the two first adjustment components are symmetrically distributed on both sides of the first connecting part 11 along the axis. At the same time, one of the connecting shafts 32 of the two first adjustment components is sleeved on the second adjustment rod 41, forming a cross-fitting structure of "first adjustment component + second adjustment component". The cross-fitting structure enables the components to support each other, further enhancing the overall structural stability of the mechanism and adapting to the harsh operating environment of high-voltage power equipment.

[0038] Specifically, the first limiting block 33 and the second limiting block 42 are nuts, or they can be blocks with internal threads.

[0039] Preferably, the first limiting block 33 and the second limiting block 42 are nuts. On the one hand, nuts are standard parts, which are convenient to purchase. On the other hand, nuts are easier to tighten with tools.

[0040] like Figure 6 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, there are two second adjustment components, which are symmetrically arranged on both sides of the first connecting part 11 along the axial direction.

[0041] It should be noted that two second adjustment components are configured and symmetrically distributed on both sides of the first connecting part 11 along its axial direction. Combined with the symmetrical distribution of the two first adjustment components, a symmetrical four-dimensional adjustment structure of "two first adjustment components + two second adjustment components" is formed: four adjustment components (two first and two second) are located on both sides of the first connecting part 11 along its axial direction, with the first and second adjustment components on the same side cooperating with each other. This distribution ensures that the force on both sides of the first connecting part 11 is completely balanced, avoiding structural displacement caused by too many components on one side; the symmetrically distributed second adjustment components also provide "redundancy protection," meaning that if a minor fault occurs in one side of the second adjustment component, the other side can still function normally, ensuring that the basic angle compensation function of the mechanism is not affected.

[0042] Two second adjustment components are symmetrically distributed on both sides of the first connection part 11 along the axial direction, ensuring that the overall force of the mechanism is completely balanced and avoiding problems such as structural deformation and rotation jamming caused by uneven component distribution. The two symmetrically distributed second adjustment components form a redundant structure. When a component on one side experiences slight wear or failure, the component on the other side can continue to play an auxiliary adjustment role, preventing the mechanism from failing due to the failure of a single component, improving the fault tolerance of the mechanism, ensuring the continuous and stable operation of the high-voltage disconnecting switch, and reducing equipment maintenance costs.

[0043] like Figure 3 and Figure 4 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, the first connecting part 11 is a convex shaft and the second connecting part 21 is a round hole, or the first connecting part 11 is a round hole and the second connecting part 21 is a convex shaft, with the convex shaft rotatably disposed in the round hole.

[0044] It should be noted that the fit between the convex shaft and the round hole can limit the radial displacement of the first and second connecting seats 20, ensuring that the angle adjustment is only performed around the rotation axis and avoiding unnecessary positional offset. At the same time, this fit is simple in structure and easy to process (both the convex shaft and the round hole can be achieved by conventional machining). The basic rotational fit assembly can be completed simply by inserting the convex shaft into the round hole, making assembly more convenient.

[0045] like Figure 4 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, a limiting bolt 51 and a limiting plate 52 are also included. The limiting plate 52 is disposed on the side of the circular hole facing away from the convex shaft. The limiting bolt 51 is coaxially disposed with the convex shaft and passes through the limiting plate 52 to be screwed to the convex shaft.

[0046] It should be noted that after the convex shaft is inserted into the round hole, the limiting plate 52 is fixed on the convex shaft by the limiting bolt 51. This can fix the convex shaft in the round hole and prevent the convex shaft from coming out along the axial direction (the direction of the rotation axis). This solves the problem that the convex shaft and the round hole can only limit radial displacement but cannot limit axial displacement.

[0047] The limit bolt 51 is coaxially screwed with the cam shaft, which can firmly fix the cam shaft in the round hole, preventing the cam shaft from coming out axially due to vibration and impact during the operation of high-voltage equipment, preventing serious power failure caused by disintegration of the mechanism, and improving the safety of the mechanism operation.

[0048] like Figure 4 As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, the end of the convex shaft protrudes from a circular hole, and the limiting plate 52 abuts against the end of the convex shaft.

[0049] Specifically, the connecting shaft 32 is mounted on the first connecting seat 10 or the second connecting seat 20 by means of a cotter pin, and the cotter pin is spaced a certain distance from the first connecting seat 10 or the second connecting seat 20, so that the connecting shaft 32 can move along the axial direction within a certain range.

[0050] It should be noted that the protruding circular hole at the end of the cam shaft allows it to move axially within a certain range, enabling slight adjustment of its axial position within the hole and further compensating for axial installation errors. Furthermore, the detachable design of the limit bolt 51 facilitates disassembly of the cam shaft and circular hole for component inspection or replacement during later maintenance.

[0051] The axial position of the fine-tuning cam shaft within the circular hole compensates for the shortcomings of existing technologies that can only compensate for angular deviations but not axial deviations, further enhancing the mechanism's adaptability to installation errors and ensuring precise docking between the operating lever 72 and the shaft head 71.

[0052] like Figure 1As shown, in a specific embodiment of the high-voltage switchgear operating device provided in this invention, the first connecting seat 10 and the second connecting seat 20 are fixedly connected to the operating rod 72 and the shaft head 71 respectively via a pin 60.

[0053] It should be noted that the connection method remains consistent with existing equipment, requiring no modification to the existing structures of the operating lever 72 and shaft head 71. This allows for direct installation of the angle compensation mechanism, reducing the cost of equipment upgrades (if a new connection method is used, the operating lever 72 or shaft head 71 must be replaced, resulting in extremely high costs). Furthermore, the pin shaft 60 connection is characterized by its simple structure, easy disassembly, and strong load-bearing capacity, making it suitable for the high-strength connection requirements of high-voltage power equipment. It ensures the stability of the connections between the first connecting seat 10 and the operating lever 72, and between the second connecting seat 20 and the shaft head 71, preventing torque transmission failure due to loose connections.

[0054] In addition, the first connecting seat 10 and the second connecting seat 20 can be fixedly connected to the operating rod 72 and the shaft head 71 respectively by welding, screwing or other means.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
