Description

Technical Field

[0001] This utility model relates to the field of transformer coil manufacturing technology, specifically to a transformer coil winding device that resists sudden short circuits. Background Technology

[0002] As power system voltage levels continue to increase, system capacity and individual transformer capacity also grow. Under the condition of a fixed transformer short-circuit impedance, the threat posed by short-circuit electromagnetic forces to the transformer becomes more severe. If a short circuit occurs, the short-circuit current can be 8 to 20 times greater than the transformer's rated current during operation. A short circuit can cause coil deformation, cracking of the conductor insulation, and potentially inter-turn breakdown, ultimately burning out the coil conductors.

[0003] Existing transformer coil winding devices mostly employ mechanical structures, resulting in low winding precision and susceptibility to inter-turn short circuits. Furthermore, the height of the winding rollers relative to the worktable is generally fixed, making it unsuitable for winding coils of the same length but larger dimensions or the same dimension but longer lengths, thus limiting the device's application range. It also hinders the disassembly and replacement of the wound core and coil, and the coil's outer surface easily accumulates dust during storage, making it inconvenient to wipe away dust during winding. Therefore, we propose a novel transformer coil winding device resistant to sudden short circuits. Utility Model Content

[0020] Please see Figure 1-3This utility model provides a technical solution: a transformer coil winding device for resisting sudden short circuits, comprising: a base 1, with an installation groove 2 and a sliding groove 13 on one side of the top of the base 1, the two sliding grooves 13 being symmetrically arranged on both sides of the installation groove 2, a slider 14 being slidably connected to the inner cavity of the sliding groove 13, the sliding groove 13 providing a good limiting and guiding effect on the slider 14, and a vertical plate 9 being symmetrically fixedly connected to the other side of the top of the base 1; a distance adjustment component 3 and a height adjustment component 4, the distance adjustment component 3 being disposed in the inner cavity of the installation groove 2, the two height adjustment components 4 being symmetrically arranged on the top of the distance adjustment component 3, and a winding roller 5 being provided between the two height adjustment components 4, a wire fixing groove being opened on one side of the winding roller 5, one end of the cable being fixed to the inner cavity of the wire fixing groove before winding, facilitating the winding operation; a cleaning component 10 and a limiting and guiding component 11, the cleaning component 10 being disposed between the two vertical plates 9, and the limiting and guiding component 11 being fixedly connected to the top of the cleaning component 10.

[0021] Specifically, such as Figure 2 As shown, the distance adjustment assembly 3 includes a second motor 3.1, a bidirectional lead screw 3.2, and moving blocks 3.3. The second motor 3.1 is fixedly connected to one side of the base 1. The output end of the second motor 3.1 passes through the inner cavity of the mounting groove 2 and is fixedly connected to the bidirectional lead screw 3.2. One end of the bidirectional lead screw 3.2 is rotatably connected to the inner cavity of the mounting groove 2 via a bearing. The two moving blocks 3.3 are symmetrically slidably sleeved on both ends of the bidirectional lead screw 3.2, and the moving blocks 3.3 and the bidirectional lead screw 3.2 are connected by threaded groove engagement. Before starting to wind the coil, after adjusting the height of the adjusting plate 4.2 via the height adjustment assembly 4, the second motor 3.1 is started, driving the bidirectional lead screw 3.2 to rotate, thereby driving the two moving blocks 3.3 to move towards each other, causing the two adjusting plates 4.2 to move towards the middle. This allows the two locking blocks 7 to be inserted into the inner cavities of the locking slots 8 at both ends of the winding roller 5, thereby fixing the winding roller 5 for easy winding of the transformer cable, facilitating installation and disassembly. At the same time, various types of winding rollers 5 can be freely fixed, improving the application range of the device.

[0022] Specifically, such as Figure 2 , Figure 3As shown, the height adjustment assembly 4 includes an adjustment seat 4.1, an adjustment plate 4.2, and an electric telescopic rod 4.3. The bottom center of the adjustment seat 4.1 is fixedly connected to the top of the moving block 3.3, and the two sides of the bottom of the adjustment seat 4.1 are fixedly connected to the top of the slider 14. Two electric telescopic rods 4.3 are symmetrically fixedly connected to the bottom of the inner cavity of the adjustment seat 4.1, and the adjustment plate 4.2 is fixedly connected to the top of the electric telescopic rod 4.3. The adjustment plate 4.2 is slidably connected to the inner cavity of the adjustment seat 4.1, and the adjustment seat 4.1 provides a good limiting and guiding function for the adjustment plate 4.2. Before the winding operation, the electric telescopic rod 4.3 is activated to push the adjustment plate 4.2 up and down, so as to facilitate the adjustment of the height of the adjustment plate 4.2 according to different models of winding rollers 5, thereby meeting the needs of winding operations for coils of the same length but larger size or coils of the same size but longer length, and improving the application range of the device.

[0023] Two adjusting plates 4.2 are rotatably connected to opposite sides via bearings, with locking blocks 7 in an irregular cross shape. A motor 6 is fixedly connected to one side of one adjusting plate 4.2, and the output end of the motor 6 passes through the adjusting plate 4.2 and is fixedly connected to one side of the locking block 7. The winding roller 5 has symmetrical slots 8 on both sides, which engage with the locking blocks 7. After adjusting the height of the adjusting plates 4.2, the distance adjustment component 3 is activated, causing the two locking blocks 7 to be inserted into the slots 8 at both ends of the winding roller 5. At this time, one end of the cable to be wound is fixed to the inner cavity of the cable groove, and the motor 6 is started to drive the locking blocks 7 to rotate, thereby driving the winding roller 5 to rotate, and the coil winding operation can begin.

[0024] Specifically, such as Figure 2 As shown, the cleaning assembly 10 includes a limiting plate 10.1 and brushes 10.2. The limiting plate 10.1 is symmetrically fixed between two upright plates 9. Several brushes 10.2 are evenly fixed on opposite sides of the two limiting plates 10.1. A collection box 12 is fixedly connected to the top of the base 1 and below the limiting plate 10.1. The inner diameter of the opening at the top of the collection box 12 is larger than the width of the limiting plate 10.1, which facilitates the falling of dust and impurities into the inner cavity of the collection box 12. The collection box 12 and the limiting plate 10.1 are on the same vertical line.

[0025] Specifically, such as Figure 3As shown, the limiting guide assembly 11 includes an electric slide rail 11.1, an electric slider 11.2, and a limiting ring 11.3. The electric slide rail 11.1 is fixedly connected to the top of the limiting plate 10.1. The electric slider 11.2 is disposed in the inner cavity of the electric slide rail 11.1 and is configured as an inverted L-shape. The limiting ring 11.3 is fixedly connected to one side of the top of the inner cavity of the electric slider 11.2 and is located facing the winding roller 5. The center of the limiting ring 11.3 is on the same horizontal line as the midline of the two limiting plates 10.1. Before starting to wind the transformer coil cable, the cable to be wound is first passed through the brush 10.2 between the two limiting plates 10.1 and through the middle of the limiting ring 11.3, and then fixed in the inner cavity of the fixing groove. During the winding operation, the brush 10.2 can clean the dust and impurities on the surface of the cable from all directions. The cleaned dust and impurities are collected by the collection box 12 to prevent environmental pollution during operation. Furthermore, during the winding process, the electric slider 11.2 is activated, causing the electric slider 11.2 to drive the limiting ring 11.3 to reciprocate at a uniform speed on the electric slide rail 11.1. This facilitates the uniform winding of the cable onto the winding roller 5, achieving the purpose of uniform winding, reducing the probability of the coil getting tangled or over-stacking during the winding process, ensuring the cable arrangement is dense, and improving the coil's resistance to sudden short circuits.

[0026] It should be noted that this utility model is a transformer coil winding device for resisting sudden short circuits. Before winding, the electric telescopic rod 4.3 is activated to push the adjusting plate 4.2 up and down, thus facilitating the adjustment of the height of the adjusting plate 4.2 according to different models of winding rollers 5. Then, the motor 3.1 is activated to drive the bidirectional lead screw 3.2 to rotate, thereby driving the two moving blocks 3.3 to move towards each other, causing the two adjusting plates 4.2 to move towards the center. This allows the two locking blocks 7 to be inserted into the slots 8 at both ends of the winding roller 5, thus fixing the winding roller 5. Then, one end of the cable to be wound is fixed into the wire-fixing groove. The motor 6 is activated to drive the locking blocks 7 to rotate, thereby driving the winding roller 5 to rotate, and the coil winding work can begin. This facilitates the installation and disassembly of the winding roller 5, and can freely fix various models of winding rollers 5, thus meeting the needs of winding coils of the same length but larger dimensions or the same dimension but longer lengths, improving the application range of the device.

[0027] Before winding the transformer coil cable, the cable to be wound is first passed through the brush 10.2 between the two limiting plates 10.1 and through the middle of the limiting ring 11.3, and then fixed into the inner cavity of the fixing groove. During the winding operation, the brush 10.2 can clean the dust and impurities on the surface of the cable from all directions. The cleaned dust and impurities are collected by the collection box 12 to prevent environmental pollution. During the winding process, the electric slider 11.2 is activated, which drives the limiting ring 11.3 to make uniform reciprocating motion on the electric slide rail 11.1. This facilitates the even and consistent winding of the cable onto the winding roller 5, achieving the purpose of uniform winding, reducing the probability of knotting and excessive stacking of the coil during the winding process, ensuring a dense cable arrangement, and improving the coil's resistance to sudden short circuits.
