Description

Technical Field

[0001] This application relates to the field of high-voltage electrical equipment technology, and in particular to a construction device for a high-frequency harmonic flexible measuring coil for high-voltage electrical equipment. Background Technology

[0002] With the large-scale integration of renewable energy and the re-electrification of the load side, a large number of power sources, loads, and energy storage devices with diverse characteristics are connected to the existing power system via power electronics interfaces. This is rapidly driving the power system towards a trend of high proportion of renewable energy and high proportion of power electronic equipment integration (referred to as "dual high"). With the continuous promotion of high-voltage, high-capacity converter equipment in the transmission network and the widespread application of power electronics technology on the distribution and consumption sides, the "dual high" characteristics will become more pronounced, becoming an important technical feature of the next-generation power system. The power system has undergone tremendous changes in both its grid structure and energy form. The new power system is characterized by nonlinearity, time-varying nature, heterogeneity, uncertainty, and complexity. Under the new power system model, the interaction between power electronic equipment and wind and photovoltaic converters with the grid leads to non-characteristic high-frequency harmonic oscillations, amplification, and instability in the range of hundreds of hertz to over kilohertz. Low frequencies exceed the well-known range of 0.01–2.5 hertz, the complexity of harmonic components increases significantly, their flow direction is uncertain, and their propagation mechanisms are complex.

[0003] The harmonic problems caused by the "high-voltage and high-efficiency" characteristics of new power systems are becoming increasingly prominent, with a significant increase in harmonic components, unpredictable flow directions, and complex propagation mechanisms. Harmonics have a major impact on the safe operation of power equipment, easily causing equipment overheating, accelerating equipment aging and shortening equipment lifespan, increasing the electrical stress and overvoltage on the equipment insulation medium, and easily causing operational errors and malfunctions of relay protection devices. Accurate measurement of high-order harmonic current components of high-voltage electrical equipment has significant engineering value.

[0004] Currently, the most common instrument for measuring the high-order harmonic current components of high-voltage electrical equipment is the flexible current transformer measuring coil. This type of coil generally has the characteristics of flexibility and open structure, which makes it easy to install in a closed loop at the high-voltage end of the power equipment. The difficulty of this process is that high-voltage live equipment is generally inaccessible to humans, and it requires people to climb or close or disassemble the flexible high-frequency current measuring coil in a narrow space. Therefore, designing and manufacturing a flexible measuring coil construction device that is suitable for high-potential operations, has reliable insulation performance, and is portable and easy to use has important practical engineering application value and market promotion prospects.

[0035] like Figures 1 to 6 As shown, this application embodiment provides a construction device for a high-frequency harmonic flexible measurement coil for high-voltage electrical equipment, including...

[0036] Lifting mounting base;

[0037] A fixed-position structure is installed at both ends of the lifting mounting base;

[0038] Disassemble the closed structure and movably set it on the fixed structure at both ends of the lifting mounting base;

[0039] The disassembly and closure structure clamps the component 4 to be constructed, and the position of the disassembly and closure structure is fixed by the position fixing structure and the component 4 to be constructed is fixed on the disassembly and closure structure. The disassembly and closure structure is moved to the high-frequency harmonic measurement position by using the lifting mounting base. The disassembly and closure structures at both ends of the lifting mounting base are moved in coordination to close and install the component 4 to be constructed at the high-frequency harmonic measurement position or to disassemble and remove the component 4 from the high-frequency harmonic measurement position.

[0040] In this embodiment, the lifting mounting base includes a lifting rod 1 and a connecting rod 2 connected to the lifting rod 1. Both ends of the connecting rod 2 are equipped with a position fixing structure and a disassembly / closure structure. The lifting rod 1 drives the connecting rod 2 to move up and down, thereby causing the position fixing structure and the disassembly / closure structure mounted on the connecting rod to move up and down.

[0041] It should be noted that the connecting rod 2 is T-shaped. The connecting rod 2 is installed at the top of the lifting rod 1. The lifting rod 1 can be raised and lowered. In this embodiment, the component 4 to be constructed can be a coil for measuring high-frequency harmonics of high-voltage electrical equipment. A fixing block 5 is provided on one end of the component 4 to be constructed, and a corresponding insertion hole matching the other end of the component 4 to be constructed is provided on the fixing block 5.

[0042] In this embodiment of the application, the high-voltage electrical equipment high-frequency harmonic flexible measurement coil construction device has a disassembly and closure structure and a position fixing structure at both ends of the connecting rod. By cooperating with the two disassembly and closure structures, the component to be constructed is first placed on the disassembly and closure structure, and the position of the disassembly and closure structure is adjusted by the position fixing structure. Then, by cooperating with the two disassembly and closure structures, the component to be constructed is placed on the high-frequency harmonic measurement position or removed from the high-frequency harmonic measurement position.

[0043] This application provides a construction device for a high-frequency harmonic flexible measurement coil for high-voltage electrical equipment, comprising a lifting mounting base, a position fixing structure, and a disassembly and closure structure. The position fixing structure is installed at both ends of the lifting mounting base, and the disassembly and closure structure is movably mounted on the position fixing structure at both ends of the lifting mounting base. The disassembly and closure structure clamps the component to be constructed, and the position fixing structure fixes the position of the disassembly and closure structure and the component to be constructed is fixed on the disassembly and closure structure. The lifting mounting base is used to move the disassembly and closure structure to the high-frequency harmonic measurement position, and the disassembly and closure structures at both ends of the lifting mounting base cooperate to close and install the component to be constructed at the high-frequency harmonic measurement position or to disassemble and remove the component to be constructed from the high-frequency harmonic measurement position. This high-voltage electrical equipment high-frequency harmonic flexible measuring coil installation device achieves the installation of high-order harmonic current measuring instruments on high-voltage electrical equipment by disassembling and fixing both ends of the lifting mounting base using a closed structure and a position fixing structure. The two structures work together to first place the component to be installed on the closed structure, then adjust its position using the position fixing structure. Finally, the two structures work together to place the component at the high-frequency harmonic measurement position or remove it from that position. This eliminates the need for manual climbing during installation, reducing the risk to workers. It solves the technical problem that the installation of high-order harmonic current measuring instruments on high-voltage electrical equipment is currently done manually, resulting in time-consuming, labor-intensive, and high-risk operations.

[0044] like Figure 3 , Figure 5 and Figure 6As shown, in one embodiment of this application, the position fixing structure includes an extension seat 11 mounted on a lifting mounting base. A drive element 12 and two lifting elements 20 are mounted on the extension seat 11. The output end of the drive element 12 is connected to each lifting element 20. One end of each lifting element 20 is connected to a pressing element 19, and the other end of each lifting element 19 abuts against a lateral moving element 10. The pressing element 16 is also connected to a mounting connector 15. The disassembly and closure structure is mounted on the mounting connector 15. The drive element 12 drives the lifting elements 20 to move up and down, causing the pressing element 19 to lift or press down the mounting connector 15 to adjust and fix the position of the disassembly and closure structure. It also causes the lateral moving element 10 to move closer to or away from the extension seat 11 to loosen or press the disassembly and closure structure onto the element 4 to be constructed. The mounting connector 15 is installed inside the lifting mounting base, and a corresponding moving groove 18 is provided in the lifting mounting base to accommodate the movement of the mounting connector 15.

[0045] It should be noted that the lifting element 20 can be a lifting plate, the pressing element 19 can be a pressing rod, and the driving element 12 can be a cylinder. The moving slot 18 is formed on the connecting rod 2. The driving element 12 drives the lifting element 20 to move in the extension seat 11, and the mounting connector 15 moves in the moving slot. In this embodiment, when the lifting element 20 moves, the surface of the lifting element 20 contacts the end of the transverse moving element 10, and the lifting element 20 pushes against the transverse moving element 10 to move, so that the end of the transverse moving element 10 pushes against the element 4 to be constructed inside the area of ​​the fixing plate 8. The surface of the extension seat 11 is provided with a lifting slot, the pressing element 19 is located in the lifting slot, and the pressing element 19 can move up and down in the lifting slot.

[0046] like Figures 3 to 6 As shown, in one embodiment of this application, the disassembly and closure structure includes an arc-shaped plate 3 mounted on the mounting connector 15, a moving mechanism movably mounted on the arc-shaped plate 3, and a clamping mechanism mounted on the moving mechanism to clamp the component 4 to be constructed. A groove 7 is provided on the arc-shaped plate 3, and the moving mechanism moves on the groove 7. The moving mechanism includes a drive source 14, a transmission component 13 connected to the output end of the drive source 14, and a force-bearing plate 16 connected to the transmission component. A connecting block 17 is mounted on the force-bearing plate 16, which is disposed in the groove 7. The clamping mechanism is mounted on the connecting block 17, and the surface of the transmission component 13 is located in the groove 7. The drive source 14 drives the force-bearing plate 16 to move up and down in the groove 7 via the transmission component 13, thereby moving the clamping mechanism in the groove 7. The clamping mechanism includes a fixed plate 8 and an expansion plate 9. The fixed plate 8 is mounted on the connecting block 17, and a region for accommodating the component 4 to be constructed is provided within the fixed plate 8. A lateral moving component 10 is inserted into and moves within the region of the fixed plate 8.

[0047] It should be noted that the transmission component 13 is a gear, and the force plate 16 is provided with teeth that mesh with the gear. The rotation of the gear can drive the force plate 16. The drive source 14 can be a motor. The fixing plate 8 is elastic, and the area of ​​the fixing plate 8 is used to place the component 4 to be constructed. The diameter of the area of ​​the fixing plate 8 is the same as the diameter of the component 4 to be constructed. The fixing plate 8 moves so that the component 4 to be constructed is inserted into the insertion hole of the fixing block 5. The component 4 to be constructed can be sleeved on the outside of the live conductor of the high-voltage electrical equipment. The component 4 to be constructed is fixed to the fixing block 5. The surface of the fixing block 5 has insertion holes. The end of the component 4 to be constructed can be inserted into the insertion hole of the fixing block 5. One end of the lateral moving component 10 is inserted into the inside of the extension seat 11, and the other end of the lateral moving component 10 can move inside the area of ​​the fixing plate 8. The lifting component 20 pushes the lateral moving component 10 so that the end of the lateral moving component 10 holds the component 4 to be constructed inside the area of ​​the fixing plate 8, thereby clamping and fixing the component 4 to be constructed in the fixing plate 8.

[0048] In this embodiment of the application, the working principle of the high-voltage electrical equipment high-frequency harmonic flexible measurement coil construction device is as follows:

[0049] The component to be installed, 4, is secured in the fixed plate 8. The lifting element 20 is moved by the driving element 12, causing the lowering rod 19 to descend, which in turn lowers the mounting connector 15, fixing the positions of the first arc-shaped plate 3 and the second arc-shaped plate 6. The lifting element 20 pushes against the lateral moving element 10, causing the end of the lateral moving element 10 to hold the component to be installed, 4, within the area of ​​the fixed plate 8, thus stabilizing it. The connecting rod 2 is then raised by the lifting rod 1, and the component to be installed, 4, is fitted onto it. The driving source 14 drives the transmission component 13 to rotate, which in turn moves the force plate 16, causing the fixed plate 8 to move. This allows the end of the component to be installed, 4, to be inserted into the insertion hole of the fixed block 5, thus allowing the component to be installed onto the live conductor of the high-voltage electrical equipment. On the outside; when removing the component to be constructed 4, the shape of the expansion plate 9 makes it easy to clamp the component to be constructed 4 in the fixing plate 8, and the arc plate 3 can move to match the shape of the component to be constructed 4. After the component to be constructed 4 is fixed by the transverse moving element 10, the fixing plate 8 moves to pull the end of the component to be constructed 4 out of the fixing block 5 so that the component to be constructed 4 can be removed without manual removal and replacement. The lifting element 20 pushes the transverse moving element 10 so that the end of the transverse moving element 10 holds the component to be constructed 4 inside the area of ​​the fixing plate 8, stabilizing the component to be constructed 4. The lifting rod 1 drives the connecting rod 2 to rise and put the component to be constructed 4 on it. The fixing plate 8 moves to pull the end of the component to be constructed 4 out of the fixing block 5 so that the component to be constructed 4 can be removed.

[0050] The high-voltage electrical equipment high-frequency harmonic flexible measurement coil construction device inserts the element to be measured into an arc-shaped groove, so that the element to be measured is stuck in the moving plate. The limiting strip stabilizes the element to be measured in the moving plate, and the moving plate is equipped with rollers inside, which facilitates the movement of the element to be measured in the moving plate. The element to be measured is moved so that the end of the element to be measured is inside the moving plate. Pushing the push rod makes the moving plate insert 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 element to be measured makes the element to be measured into the receiving channel. Pulling the element to be measured from the other side removes the moving plate. The clamping rotating element is held against the surface of the element to be measured. The position of the element to be measured can be changed by driving the gear to rotate through the drive element. When the clamping rotating element does not rotate, the element to be measured is clamped and fixed.
