Description

Technical Field

[0001] This application relates to the field of high-voltage electrical equipment technology, and in particular to a clamping device for high-order harmonic broadband measurement coils of high-voltage power equipment. Background Technology

[0002] With the continuous development of new power systems, a large number of power electronic devices and power supply terminals such as wind, solar, and energy storage are being connected to the power grid, making the harmonic problem of the power grid increasingly prominent. High-voltage power equipment exhibits a significant increase in harmonic components, with unpredictable flow directions and complex propagation mechanisms. Because high-order harmonics have a major impact on the operational safety of power equipment, easily causing overheating, accelerating aging and shortening service life, increasing electrical stress and overvoltage on the insulation medium, and causing operational errors and malfunctions in relay protection devices, accurate measurement of high-order harmonic current components in high-voltage electrical power equipment has significant engineering value. Currently, the most common measuring instrument is the flexible current transformer measuring coil. This coil generally has a flexible, open structure, facilitating closed-loop installation at the high-voltage end of the power equipment. It can accurately measure broadband harmonic currents flowing through high-voltage energized conductors, with a very broad application prospect and a large market demand in the power equipment operation and maintenance field.

[0003] Currently, flexible measuring coils require specialized winding devices during fabrication. High-harmonic broadband measuring coils require a clamping structure to hold the element under test, and the number of coil turns and the winding position must be precisely positioned. The enameled wire is then wound onto the element under test using the winding device. Existing devices for holding the element under test clamp it, and the winding device winds the wire. After winding to the current position, the clamping device must be released, the position of the element under test adjusted, and then it must be fixed again before winding can continue. Summary of the Invention

[0004] This application provides a clamping device for high-order harmonic broadband measurement coils of high-voltage power equipment, which solves the technical problem that the existing winding clamping structure for preparing flexible measurement coils cannot change the position of the coil winding, resulting in low efficiency in preparing flexible measurement coils.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0006] On the one hand, a clamping device for high-order harmonic broadband measurement coils of high-voltage power equipment is provided, comprising:

[0007] Base;

[0008] A clamping and moving structure is movably mounted on the base, the clamping and moving structure including a moving mechanism and a clamping and rotating mechanism connected to the moving mechanism;

[0009] The moving mechanism is used to move the component to be measured onto the clamping and rotating mechanism;

[0010] The clamping and rotating mechanism is used to clamp the component to be measured and rotate the component to change the detection position of the component.

[0011] Preferably, the moving mechanism includes a movable block movably disposed on the base, the movable block having an arc-shaped groove, a movable piece being disposed in the arc-shaped groove to accommodate the element to be measured, and a sliding groove being disposed on the movable block to accommodate a push rod, the push rod passing through the sliding groove and being fixedly connected to the movable piece; the element to be measured is moved onto the clamping and rotating mechanism by moving the movable piece through the movement of the push rod.

[0012] Preferably, the movable piece has limiting strips protruding from both sides to prevent the element to be measured from moving.

[0013] Preferably, the movable piece is provided with several rollers to facilitate the movement of the element to be measured, and the rollers roll on the inner wall of the movable piece.

[0014] Preferably, a positioning plug is provided on the movable piece near one end of the clamping and rotating mechanism, and a plug hole is provided on the upright plate of the clamping and rotating mechanism corresponding to the plug.

[0015] Preferably, the clamping and rotating mechanism includes a vertical plate connected to the connecting column in the moving mechanism. The vertical plate has a receiving channel for accommodating the component to be measured transported by the moving mechanism. Clamping and rotating assemblies for clamping the component to be measured and changing the detection position of the component to be measured are provided on both sides of the receiving channel.

[0016] Preferably, the clamping rotation assembly includes a driving element and a clamping rotation element. The output shaft of the driving element is rotatably connected to the clamping rotation element. The clamping rotation element has several protruding locking pins. The clamping rotation assembly also includes a force-receiving ring that abuts against the insertion block in the moving mechanism. The moving mechanism moves the element to be measured to the receiving channel, and the insertion block pushes the force-receiving ring, causing the clamping rotation element to rotate so that the locking pins are not located in the receiving channel. The driving element drives the clamping rotation element to rotate, thereby causing the element to be measured in the receiving channel to rotate, thus changing the detection position of the element to be measured. The driving element does not drive the clamping rotation element to rotate, and the locking pins clamp the element to be measured in the receiving channel, thereby clamping and fixing the element to be measured.

[0017] Preferably, a limiting ring is provided on the output shaft of the driving element, and a groove matching the limiting ring is formed in the force ring. The force ring is connected to the driving element through the limiting ring.

[0018] Preferably, the bottom end of the output shaft of the drive element is provided with a limiting gear for rotation limiting that is connected to the clamping rotating element.

[0019] Preferably, several elastic elements for buffer reset are fixedly connected to the output shaft of the drive element.

[0020] As can be seen from the above technical solutions, the embodiments of this application have the following advantages: The high-voltage power equipment high-order harmonic broadband measurement coil clamping device includes a base and a clamping moving structure movably disposed on the base; the clamping moving structure includes a moving mechanism and a clamping rotating mechanism connected to the moving mechanism; the moving mechanism is used to move the element to be measured onto the clamping rotating mechanism; the clamping rotating mechanism is used to clamp the element to be measured and rotate the element to be measured to change the detection position of the element to be measured. This high-voltage power equipment high-order harmonic broadband measurement coil clamping device moves the element to be measured to the clamping rotating mechanism through the moving mechanism, and also rotates the element to be measured through the clamping rotating mechanism to change the detection position of the element to be measured, thereby realizing the change of detection position during the measurement process of the element to be measured, improving measurement efficiency, and solving the technical problem that the existing winding clamping structure for flexible measurement coil fabrication cannot achieve the change of coil winding position, resulting in low efficiency in the fabrication of flexible measurement coils.

[0034] like Figure 1 As shown, this application embodiment provides a clamping device for high-order harmonic broadband measurement coils of high-voltage power equipment, including...

[0035] Base 1;

[0036] A clamping and moving structure is movably mounted on the base 1. The clamping and moving structure includes a moving mechanism and a clamping and rotating mechanism connected to the moving mechanism.

[0037] A moving mechanism is used to move the element to be measured 6 onto the clamping and rotating mechanism;

[0038] The clamping and rotating mechanism is used to clamp the element 6 to be measured and rotate the element 6 to change the detection position of the element 6.

[0039] In this embodiment, the base 1 serves as a support, and a slide rail 3 is also provided on the base 1. The moving mechanism and the clamping and rotating mechanism move on the slide rail 3.

[0040] It should be noted that a connection terminal 2 for performing high-order harmonic broadband measurement on the base 1 located at the other end of the clamping and moving structure is installed. In this embodiment, the connection terminal 2 is connected to the component 6 under test via a connecting pipe to realize the high-order harmonic broadband measurement of the component 6 under test. The component 6 under test can be a coil that needs to be measured for high-order harmonic broadband, or a linear product that needs to be measured.

[0041] In this embodiment of the application, the high-voltage power equipment high-order harmonic broadband measurement coil clamping device moves the element to be measured to the clamping and rotating mechanism through the moving mechanism, and also rotates the element to be measured through the clamping and rotating mechanism to change the detection position of the element to be measured.

[0042] This application provides a high-voltage power equipment high-harmonic broadband measurement coil clamping device, including a base and a clamping moving structure movably mounted on the base. The clamping moving structure includes a moving mechanism and a clamping rotating mechanism connected to the moving mechanism. The moving mechanism is used to move the element to be measured onto the clamping rotating mechanism; the clamping rotating mechanism is used to clamp the element to be measured and rotate the element to change its detection position. This high-voltage power equipment high-harmonic broadband measurement coil clamping device moves the element to be measured onto the clamping rotating mechanism via the moving mechanism and rotates the element to be measured via the clamping rotating mechanism to change its detection position. This achieves a change in the detection position during the measurement process, improving measurement efficiency and solving the technical problem that existing flexible measurement coil preparation winding clamping structures cannot achieve changes in the coil winding position, resulting in low efficiency in flexible measurement coil preparation.

[0043] like Figures 2 to 4 As shown, in one embodiment of this application, the moving mechanism includes a movable block 5 movably disposed on the base 1. An arc-shaped groove 10 is provided on the movable block 5, and a movable piece 14 for accommodating the element to be measured 6 is disposed in the arc-shaped groove 10. A sliding groove 51 for accommodating a push rod 9 is provided on the movable block 5. The push rod 9 passes through the sliding groove 51 and is fixedly connected to the movable piece 14. The movable piece 14 is moved by the movement of the push rod 9 to move the element to be measured 6 onto the clamping and rotating mechanism.

[0044] It should be noted that the movable block 5 is provided with a connecting member 52 that is connected to the clamping and rotating mechanism. In this embodiment, the arc-shaped groove 10 is formed on the top surface of the movable block 5.

[0045] like Figure 4 As shown, in one embodiment of this application, the movable piece 14 has limiting strips 11 protruding from both sides to prevent the measured element 6 from moving.

[0046] It should be noted that the limiting strip 11 is provided on both sides of the arc groove 10, and the limiting strip 11 can prevent the measured element 6 from moving up and down during the movement.

[0047] like Figure 4 As shown, in one embodiment of this application, the movable piece 14 is provided with several rollers 12 to facilitate the movement of the element 6 to be measured, and the rollers 12 roll on the inner wall of the movable piece 14.

[0048] It should be noted that the roller 12 facilitates the movement of the element to be measured 6 in the moving plate 14.

[0049] like Figure 4 and Figure 5 As shown, in one embodiment of this application, a positioning plug 13 is provided on the movable piece 14 near one end of the clamping and rotating mechanism, and a plug hole 16 is provided on the upright plate of the clamping and rotating mechanism corresponding to the plug 13.

[0050] It should be noted that the high-voltage power equipment high-order harmonic broadband measurement coil clamping device can move on the surface of the moving block 5 via the push rod 9. The end of the push rod 9 is connected to the moving piece 14 inside the arc groove 10. The moving piece 14 moves with the push rod 9. The surface of the moving piece 14 is provided with a slot 15. The surface of the moving piece 14 is fixed with a plug-in block 13. The clamping rotation mechanism is provided with a plug-in hole 16. The plug-in block 13 can be inserted into the plug-in hole 16.

[0051] like Figure 5 and Figure 6 As shown, in one embodiment of this application, the clamping and rotating mechanism includes a vertical plate 4 connected to a connecting column in the moving mechanism. The vertical plate 4 has a receiving channel 17 for accommodating the moving mechanism to transport the element to be measured 6. Clamping and rotating assemblies for clamping the element to be measured 6 and changing the detection position of the element to be measured 6 are provided on both sides of the receiving channel 17.

[0052] It should be noted that the movable piece 14 can be inserted into the receiving channel 17. The two sets of clamping rotating components of the high-voltage power equipment high-order harmonic broadband measurement coil clamping device are driven in opposite directions.

[0053] like Figure 5 and Figure 6 As shown, in one embodiment of this application, the clamping rotation assembly includes a driving element 8 and a clamping rotation element 22. The output shaft 18 of the driving element 8 is rotatably connected to the clamping rotation element 22. Several locking pins protrude from the clamping rotation element 22. The clamping rotation assembly also includes a force-receiving ring 20 that abuts against the insertion block 13 in the moving mechanism. The moving mechanism moves the element to be measured 6 to the receiving channel 7, and the insertion block 13 pushes the force-receiving ring 20, causing the clamping rotation element 22 to rotate so that the locking pins are not located in the receiving channel 7. The driving element 8 drives the clamping rotation element 22 to rotate, thereby causing the element to be measured 6 in the receiving channel 7 to rotate, so as to change the detection position of the element to be measured 6. The driving element 8 does not drive the clamping rotation element 22 to rotate, and the locking pins lock the element to be measured 6 in the receiving channel 7 to clamp and fix the element to be measured 6.

[0054] It should be noted that the clamping rotating element 22 can be a gear, and the corresponding locking pin is the gear tooth. The clamping rotating element 22 can enter the interior of the receiving channel 7. The driving element 8 can be a motor.

[0055] like Figure 5 and Figure 6 As shown, in one embodiment of this application, a limiting ring 24 is provided on the output shaft 18 of the drive element 8, and an annular groove 21 matching the limiting ring 24 is provided in the force ring 20. The force ring 20 is connected to the drive element 8 through the limiting ring 24. A limiting gear 23 for rotation limiting is provided at the bottom end of the output shaft of the drive element 8 and is connected to the clamping rotating element 22. Several elastic elements 19 for buffer reset are fixed on the output shaft 18 of the drive element 8.

[0056] It should be noted that the elastic element 19 can be a spring. An elastic element 19 is fixed to the surface of the output shaft 18 of the drive element 8, and a force-receiving ring 20 is provided at the end of the output shaft 18. One end of the elastic element 19 is fixedly connected to the output shaft 18, and the other end is fixedly connected to the surface of the force-receiving ring 20. A limiting ring 24 is provided on the surface of the output shaft 18 of the drive element 8 to prevent the output shaft 18 from falling off. The limiting ring 24 is inserted into the annular groove 21 on the inner wall of the force-receiving ring 20. The limiting ring 24 can move within the annular groove 21. A limiting gear 23 is fixed to the end of the output shaft 18 of the drive element 8, and a clamping rotating element 22 is provided at the bottom of the output shaft 18 of the drive element 8. The limiting gear 23 is located inside the clamping rotating element 22 and can move inside the clamping rotating element 22. The clamping rotating element 22 rotates with the output shaft 18 of the drive element 8 and can enter the interior of the receiving channel 7.

[0057] In this embodiment of the application, the working principle of the high-voltage power equipment high-order harmonic broadband measurement coil clamping device is as follows:

[0058] The element to be measured 6 is inserted into the arc-shaped groove 10, so that the element to be measured 6 is stuck in the moving plate 14. The limiting strip 11 stabilizes the element to be measured 6 in the moving plate 14. The moving plate 14 is provided with rollers 12 inside, which facilitates the movement of the element to be measured 6 in the moving plate 14. The element to be measured 6 is moved so that the end of the element to be measured 6 is located inside the moving plate 14. The push rod 9 is pushed so that the moving plate 14 is inserted into the receiving channel 7. The insertion block 13 is inserted into the insertion hole 16. The 3-push force ring 20 causes the clamping rotating element 22 to move. The clamping rotating element 22 is not located in the receiving channel 7. The element to be measured 6 is pushed so that the element to be measured 6 is located in the receiving channel 7. The element to be measured 6 is pulled from the other side to remove the moving piece 14. The clamping rotating element 22 is pressed against the surface of the element to be measured 6. The clamping rotating element 22 is driven to rotate by the driving element 8 so that the position of the element to be measured 6 can be changed. When the clamping rotating element 22 does not rotate, the element to be measured 6 is clamped and fixed.

[0059] It should be noted that the plug block 13 pushes against the surface of the force ring 20, and the plug block 13 pushes against the force ring 20, causing the clamping rotating element 22 to move, and the clamping rotating element 22 is not located in the receiving channel 7. The movable piece 14 is fitted with a measuring element 6, which can move inside the movable piece 14. The surface of the measuring element 6 contacts the surface of the roller 12. The inner wall of the receiving channel 7 is provided with a connecting groove 17. An arc-shaped piece is fixed on the surface of the movable piece 14 and can be inserted into the connecting groove 17. After the measuring element 6 is inserted into the receiving channel 7, the end of the measuring element 6 is inserted into the inside of the connecting end 2, and the enameled wire is wound around the surface of the measuring element 6 by the winding device. The slide rail 3 is located on the top of the base 1. The measuring element 6 is pushed so that the measuring element 6 is located in the receiving channel 7. The measuring element 6 is pulled from the other side to pull out the movable piece 14. The clamping rotating element 22 is held against the surface of the measuring element 6. The position of the measuring element 6 can be changed by driving the clamping rotating element 22 to rotate through the driving element 8.

[0060] This high-voltage power equipment high-order harmonic broadband measurement coil clamping device inserts the measured element into an arc-shaped groove, causing the measured element to be clamped in the moving plate. The limiting strip stabilizes the measured element in the moving plate, and the moving plate is equipped with rollers inside, which facilitate the movement of the measured element in the moving plate. The measured element is moved so that the end of the measured element is inside the moving plate. Pushing the push rod causes the moving plate to be inserted into the receiving channel. The insertion block is inserted into the insertion hole. The insertion block pushes the force ring, causing the clamping rotating element to move. The clamping rotating element is not in the receiving channel. Pushing the measured element makes it into the receiving channel. Pulling the measured element from the other side removes the moving plate. The clamping rotating element presses against the surface of the measured element. The position of the measured element can be changed by driving the gear to rotate through the drive element. When the clamping rotating element does not rotate, the measured element is clamped and fixed.
