Description

Technical Field

[0001] The utility model relates to the technical field of vertical winding reactors, and particularly relates to a vertical winding reactor with special insulation. Background Art

[0002] In recent years, with the wide application of high-power power electronic devices, the demand for large-current reactors has been increasing. At present, the coils of large-current reactors are generally of foil winding structure or vertical winding structure. For the coils with foil winding structure, interlayer insulation paper needs to be added for protection in each layer of winding. Since interlayer insulation needs to be placed between each layer of copper / aluminum foil, the operation efficiency is relatively low, and the cost of insulation materials is increased.

[0003] Meanwhile, in the foil winding coil structure, the thermal conductivity of the insulation material is relatively low, resulting in a reduction in the overall heat dissipation capacity of the coil; for the conventional vertical winding structure coil, although the heat dissipation capacity is good, the insulation layer of the vertical winding wire is easily damaged, and the material scrap rate during the coil winding process reaches about 10%; at the same time, restricted by the material processing technology, the size of the vertical winding insulation wire cannot be too large, and generally the cross-sectional area of the wire can only be below 100 mm2;

[0004] However, most of the coils of the reactor are connected to the vertical winding reactor by bolts. When using the multiple-bolt connection method for a long time, when the bolts are subjected to external forces, the bolts are likely to become loose, and the rust of the bolts reduces the convenience of disassembly and maintenance of the vertical winding reactor coil, so that the vertical winding reactor coil cannot be used and installed more conveniently, reducing the practicability of the vertical winding reactor coil. Moreover, the reactor will generate a certain amount of heat during operation, especially more significantly during high-power operation or long-term operation. If the heat cannot be dissipated in time and effectively, the internal temperature of the reactor may increase, affecting its stability and service life; Summary of the Utility Model

Detailed Embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model.

[0027] Embodiment 1

[0028] Reference Figure 1 、 2 Figures 3 and 4 show the first embodiment of the present utility model, which provides a vertically wound reactor with special insulation, including a support base 1 and two groups of side plates 2. The side plates 2 are fixedly connected to the top of the support base 1. Four groups of limit holes are provided on the surface of the side plates 2, and a positioning mechanism 3 is inserted into the interior of the limit holes. Twelve groups of positioning grooves are provided on the top surface of the side plates 2, and a coil body 5 is inserted into the surface of the positioning grooves. Two connecting blocks 6 are fixedly connected to the top of the coil body 5. Positioning grooves are provided on the surface of the six connecting blocks 6, and a disassembly mechanism 4 is inserted into the interior of the positioning grooves;

[0029] The disassembly mechanism 4 includes a pin 401 inserted into the positioning groove, and two limit posts 402 are fixedly connected to the end of the pin 401.

[0030] Specifically, a rotating handle 12 is fixedly connected to the surface of the pin 401, and an anti-slip sleeve is sleeved on the surface of the rotating handle 12.

[0031] Furthermore, by rotating the pin 401, the two limit posts 402 at the end of the pin 401 form a passage with the positioning groove, and the pin 401 can be separated from the positioning groove, so that it is convenient for the staff to remove the coil body 5 from the device and regularly replace and maintain the coil body 5. Similarly, by inserting the pin 401 into the positioning groove and then rotating the pin 401 to stagger the two limit posts 402 at the end of the pin 401 from the positioning groove, the installation can be completed. The operation is convenient and the structure is simple.

[0032] Embodiment 2

[0033] Reference Figure 1 and 3 show the second embodiment of the present utility model. Based on the previous embodiment, a motor box 9 is fixedly connected to the surface of the fixing plate 8, a driving mechanism 10 is fixedly connected to the interior of the motor box 9, and a heat dissipation fan 11 is threadedly connected to the surface of the driving mechanism 10.

[0034] The driving mechanism 10 includes a servo motor 1001 fixedly connected to the interior of the motor box 9. A transmission rod 1002 is splined to the output end of the servo motor 1001. One end of the transmission rod 1002 is fixedly connected to a lead screw 1003, and the heat dissipation fan 11 is threadedly connected to the surface of the lead screw 1003

[0035] Specifically, a limit rod 13 is fixedly connected to the top of the heat dissipation fan 11, and a limit plate 14 is fixedly connected to the upper surface of the fixing plate 8.

[0036] Further, start the servo motor 1001. The servo motor 1001 drives the lead screw 1003 on one side to rotate, so that the heat dissipation fan 11 threadedly connected to the surface of the lead screw 1003 moves left and right along the surface of the lead screw 1003, improving the heat dissipation range.

[0037] Working principle: When in use, rotate the bolt 401 so that the two limit posts 402 at the end of the bolt 401 form a passage with the positioning groove, and the bolt 401 can be separated from the positioning groove, facilitating the staff to remove the coil body 5 from the device and replace and maintain the coil body 5 regularly. Similarly, insert the bolt 401 into the positioning groove, and then rotate the bolt 401 so that the two limit posts 402 at the end of the bolt 401 are staggered from the positioning groove to complete the installation. The operation is convenient and the structure is simple. Secondly, start the servo motor 1001. The servo motor 1001 drives the lead screw 1003 on one side to rotate, so that the heat dissipation fan 11 threadedly connected to the surface of the lead screw 1003 moves left and right along the surface of the lead screw 1003, improving the heat dissipation range. Finally, when disassembling the side plate 2 and the support base 1, pull the positioning post 301, so that the positioning post 301 drives the support spring 302 sleeved on the surface to deform and generate elastic potential energy until the positioning post 301 is separated from the external connection structure. Release the positioning post 301, and the positioning post 301 returns to the starting position under the reverse acting force of the support spring 302 to complete the installation and disassembly of the side plate 2 and the support base 1.
