[0002] Uninterruptible power supplies (UPS) have become a hot research topic due to their ability to continuously supply power to electrical equipment. As the output power of UPS increases, the size and weight of its electronic components also increase accordingly, especially the inductors. For example, an inductor in a 275kW UPS will weigh approximately 10 kg. To improve the energy conversion efficiency of inductors, vertically wound toroidal inductors are currently used in high-power UPS systems.

[0003] A typical toroidal inductor usually consists of a circular magnetic core and a toroidal coil. The coil is formed by alternately winding copper busbars or copper strips along the inner and outer walls of the magnetic core. However, the coils wound with copper busbars are relatively heavy and difficult to fix; at the same time, the outer diameter of the coil windings can vary slightly, making it difficult to stably fix them to the base. Summary of the Invention

[0004] The purpose of this invention is to provide a toroidal inductor using a novel material, thereby solving the following technical problems:

[0005] Existing toroidal inductors have coils wound with copper busbars, which are heavy and difficult to fix. At the same time, the outer diameter of the coil windings may vary slightly, making it difficult to fix them stably on the base.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-4 As shown, the present invention is a toroidal inductor using a novel material, with a winding coil 7 wound around the outside of a toroidal magnetic core 6, and the winding coil 7 using copper-clad aluminum wire.

[0034] The winding positioning strip 4 is configured as a hollow tubular structure. The winding positioning strip 4 is located outside the winding coil 7. An air hole 5 is opened on the side of the winding positioning strip 4 facing the winding coil 7. Both ends of the winding positioning strip 4 extend into the inductor base plate 1.

[0035] Inductor base plate 1, with an extension sleeve 9 inside the inductor base plate 1, and the two ends of the winding positioning strip 4 extending into the extension sleeve 9.

[0036] The winding positioning band 4 is connected to the inductor base plate 1 through a fastening mechanism.

[0037] Specifically, by using copper-clad aluminum wire for the winding coil 7, compared to traditional copper wire, the weight of the winding coil 7 can be effectively reduced, facilitating the installation and fixation of the inductor. The winding coil 7 of the inductor is fixed by the winding positioning band 4. The winding positioning band 4 is fixed to the outside of the winding coil 7, and both ends of the winding positioning band 4 extend into the extension sleeve 9. The fastening mechanism fixes the two ends of the winding positioning band 4 downward, and the winding positioning band 4 tightens the winding coil 7, making it difficult to loosen and facilitating the fixation of the winding coil 7.

[0038] Meanwhile, the winding positioning strip 4 is set as a hollow tubular structure, and an air hole 5 is opened on the side of the winding positioning strip 4 facing the winding coil 7. When the gas temperature around the winding coil 7 is high, it can enter the winding positioning strip 4 through the air hole 5, which helps to remove the high temperature gas around the winding coil 7.

[0039] In one embodiment of the present invention, the fastening mechanism includes:

[0040] The clamping gear 2 is fixedly connected to both ends of the clamping gear 2 with gear shafts 17, and one-way bearings 16 are connected to the gear shafts 17.

[0041] Positioning belt teeth 8 are located on the outside of the winding positioning belt 4, and the positioning belt teeth 8 mesh with the clamping gear 2.

[0042] Specifically, when the clamping gear 2 is rotated, since the clamping gear 2 is installed inside the mounting bracket 3 through the one-way bearing 16, the clamping gear 2 can only rotate in one direction. The clamping gear 2 meshes with the positioning belt teeth 8. The one-way rotation of the clamping gear 2 drives the two ends of the winding positioning belt 4 to move downward through the positioning belt teeth 8, so that the winding positioning belt 4 clamps the winding coil 7 tightly and is not easy to loosen, which makes it easy to fix the winding coil 7.

[0043] Preferably, the fastening mechanism further includes:

[0044] Mounting bracket 3 is fixedly mounted on the top of inductor base plate 1, and one-way bearing 16 is located inside mounting bracket 3. Specifically, the one-way bearing 16 is located inside mounting bracket 3 to facilitate stable fixation of clamping gear 2.

[0045] In one embodiment of the present invention, the end of the winding positioning band 4 is slidably connected to the extension sleeve 9, and the bottom end of the extension sleeve 9 is connected to the conductive inner tube 10.

[0046] Specifically, the end of the winding positioning band 4 is slidably connected to the extension sleeve 9, which facilitates the sliding of the end of the winding positioning band 4 inside the extension sleeve 9.

[0047] Furthermore, the conductive inner tube 10 extends through the interior of the inductor base plate 1.

[0048] In one embodiment of the present invention, the interior of the winding positioning strip 4, the extension sleeve 9 and the conductive inner tube 10 are connected to the outside, and the conductive inner tube 10 is connected to the fan 11.

[0049] Specifically, the fan 11 sends airflow into the inner cavity of the winding positioning strip 4 through the inner tube 10 and the extension sleeve 9, and flows out through the other end of the winding positioning strip 4. The airflow inside the winding positioning strip 4 flows rapidly, which reduces the air pressure inside the winding positioning strip 4. The high-temperature gas around the winding coil 7 can be quickly drawn into the winding positioning strip 4 through the air hole 5, which helps to quickly remove the high-temperature gas around the winding coil 7, facilitates the acceleration of the gas flow around the winding coil 7, and helps to cool down the winding coil 7.

[0050] In one embodiment of the present invention, inductor pressure plates 12 are provided on both sides of the winding coil 7. The bottom end of the inductor pressure plate 12 is rotatably connected to the top end of the inductor base plate 1 via a hinge. An oblique toothed rack 13 is provided on the side of the inductor pressure plate 12 away from the winding coil 7.

[0051] Specifically, the inductor pressure plates 12 arranged on both sides of the winding coil 7 press the two sides of the winding coil 7 tightly, so that the winding coil 7 will not be deflected.

[0052] In one embodiment of the present invention, the top of the inductor base plate 1 is rotatably connected to a support rod 15 via a hinge, and the end of the support rod 15 is provided with an inclined locking block 14 that engages with the inclined toothed rack 13.

[0053] Specifically, the tilting direction of the inclined block 14 is opposite to the tilting direction of the saw teeth on the inclined tooth rack 13. When the inclined block 14 moves downward, it moves in the direction of the tilting of the saw teeth on the inclined tooth rack 13.

[0054] In one embodiment of the present invention, the deflection direction of the tilting block 14 is opposite to the deflection direction of the saw teeth on the inclined tooth rack 13.

[0055] Specifically, after the winding coil 7 is installed, the support rod 15 is rotated. The tilting direction of the inclined locking block 14 at the end of the support rod 15 is opposite to the tilting direction of the saw teeth on the inclined tooth rack 13. When the inclined locking block 14 moves downward, it moves in the same direction as the saw teeth on the inclined tooth rack 13; when the inclined locking block 14 moves upward, it moves against the tilting direction of the saw teeth on the inclined tooth rack 13. Therefore, rotating the support rod 15 causes the inclined locking block 14 to rotate downward towards the inclined tooth rack 13, but it cannot rotate in the opposite direction. Rotating the support rod 15 changes the fixed angle of the inductor pressure plate 12. The inductor pressure plate 12 rotates towards the side that presses the winding coil 7, which facilitates pressing both sides of the winding coil 7 and prevents the winding coil 7 from becoming skewed after installation.

[0056] In one embodiment of the present invention, a plurality of air holes 5 are provided, and the plurality of air holes 5 are distributed in a rectangular array on one side of the winding positioning strip 4.

[0057] The working principle of this invention: The winding coil 7 uses copper-clad aluminum wire, which can effectively reduce the weight of the winding coil 7 compared with traditional copper wire, making it easier to install and fix the inductor.

[0058] When installing the inductor winding coil 7, place the winding coil 7 on the inductor base plate 1, fix the winding positioning band 4 to the outside of the winding coil 7, and extend both ends of the winding positioning band 4 into the extension sleeve 9. Rotate the clamping gear 2. Since the clamping gear 2 is installed inside the mounting bracket 3 through the one-way bearing 16, the clamping gear 2 can only rotate in one direction. The clamping gear 2 meshes with the positioning band teeth 8. The one-way rotation of the clamping gear 2 drives both ends of the winding positioning band 4 to move downward through the positioning band teeth 8, so that the winding positioning band 4 clamps the winding coil 7 tightly and is not easy to loosen, which facilitates the fixation of the winding coil 7.

[0059] At the same time, the fan 11 sends airflow into the inner cavity of the winding positioning strip 4 through the inner tube 10 and the extension sleeve 9, and flows out through the other end of the winding positioning strip 4. The airflow inside the winding positioning strip 4 flows rapidly, which reduces the air pressure inside the winding positioning strip 4. The high-temperature gas around the winding coil 7 can be quickly drawn into the winding positioning strip 4 through the air hole 5, which helps to quickly remove the high-temperature gas around the winding coil 7, facilitates the acceleration of the gas flow around the winding coil 7, and helps to cool down the winding coil 7.

[0060] After the winding coil 7 is installed, rotate the support rod 15. The tilting direction of the inclined locking block 14 at the end of the support rod 15 is opposite to the tilting direction of the saw teeth on the inclined tooth rack 13. When the inclined locking block 14 moves downward, it moves in the same direction as the saw teeth on the inclined tooth rack 13; when the inclined locking block 14 moves upward, it moves against the tilting direction of the saw teeth on the inclined tooth rack 13. Therefore, rotating the support rod 15 causes the inclined locking block 14 to rotate downward towards the inclined tooth rack 13, but it cannot rotate in the opposite direction. Rotating the support rod 15 changes the fixed angle of the inductor pressure plate 12. The inductor pressure plate 12 rotates towards the side that presses the winding coil 7, which facilitates pressing both sides of the winding coil 7 and prevents the winding coil 7 from becoming skewed after installation.
