[0032] The following will further elaborate on the present utility model in conjunction with the attached Figure 1-5 drawings.

[0033] The embodiment of the present utility model discloses an air-cooling system for a special ozone transformer.

[0034] Referring to Figure 1 , Figure 2 , the overall transformer is installed in the box body 4, including two coil packages 1, a base 2, a clamping piece 3, a box body 4, a cooling device 5, an iron core 7, a number of bolts and a number of nuts I. The iron core 7 is in an overall shape of a square frame with a hole in the middle. The coil package 1 is wound around the two upright poles of the iron core 7. The base 2 and the clamping piece 3 are respectively above and below, and are clamped and connected to the two horizontal poles of the iron core 7. The outer surface of each bolt is threadedly connected to the inside of the nut I. The inside of the box body 4 is fixedly connected with a fixed plate 6. The two coil packages 1 are both sleeved on the outer surface of the iron core 7. The clamping piece 3 and the base 2 are respectively clamped to the top and bottom of the iron core 7 through a part of the bolts and nuts I. The bottom of the base 2 is clamped to the outer surface of the fixed plate 6 through the corresponding bolts and nuts I. The cooling device 5 is installed on the fixed plate 6 of the box body 4 through bolts and nuts I. By loosening the nut I, the cooling device 5 can be detached, and by tightening the nut I to be clamped to the fixed plate 6, the cooling device 5 is fixed.

[0035] Referring to Figure 1 、 Figure 2 Figure 3 、 Figure 4 , both coils 1 include several coils 11, retaining frames 12 and insulating paper 13. The coils 11 are large and small, all in the shape of a ring 1. The coils 11 are arranged outward from small to large horizontally with the two upright rods of the iron core 7 as the axis. In the vertical direction, coils 11 of the same size are arranged in a linear array along their axes. The coils 14 are wrapped with insulating paper 13. The gaps between the coils 11 are air ducts. The cold air blown in by the parallel fans 51 and the angle fans 52 passes through the air ducts, taking away the temperature of the coils 11 and the surface of the iron core 7, thereby achieving rapid cooling of the transformer. The interiors of several coils 11 are respectively overlapped with the outer surfaces of the two vertical rods of the iron core 7, and the two retaining frames 12 are respectively clamped to the interiors of the corresponding coils 11. The coils 11 in each coil package 1 are arranged in a linear array along the length direction of the corresponding retaining frame 12. An air duct is opened between every two corresponding coils 11, and the inner surfaces of the two insulating papers 13 are clamped to the outer surfaces of the corresponding coils 11.

[0036] Reference Figure 1 、 Figure 3 、 Figure 4 The cooling device 5 includes four parallel fans 51, two angle fans 52 and four fan racks 53. A through hole 1 is opened on one side of the four parallel fans 51. If the through hole 1 is connected to a different through hole 2, the position of the parallel fan 51 on the C-shaped short steel is different. If the position of the through hole 2 connected to the fixing plate 6 is different, the position of the parallel fan 51 from the coil 11 is also different. According to the size of the coil 11, the parallel fan 51 and the C-shaped short steel can be placed directly under the coils 11 of different sizes by bolts and nuts. The four fan racks 53 all include The four C-shaped short steels are provided with a plurality of through holes in a linear array along their length on the top and bottom. Strip slots 54 are provided on both sides of the two angle fans 52. The length of the strip slots 54 is greater than the width. When the strip slots 54 move up and down on the surface of the bolt, the distance between the angle fan 52 and the coil 11 can be changed, so that the height of the angle fan 52 can be fine-tuned through the strip slots 54. By adjusting the strip slots 54 and connecting them with the through holes of different heights, the height of the angle fan 52 can be adjusted.

After the long screws 8 and the two nuts are tightened, the corresponding two C-shaped long steels are clamped, and then the two C-shaped long steels clamp the iron core 7. The top and bottom of the two C-shaped long steels are respectively clamped to the bottom of the retaining frame 12 and the top of the fixed plate 6 through the corresponding bolts and nuts. The middle part of the two C-shaped long steels is provided with two rows of through holes three in a linear array along their length. Each long screw 8 passes through the interior of the corresponding two C-shaped long steels. Both ends of each long screw 8 are fixedly connected to a nut two, and each nut two is clamped to the outer surface of the C-shaped long steel.

The angle fans 52 can be symmetrically or asymmetrically distributed around the iron core 7. The distance between the through holes three is not fixed. There are different numbers of through holes three under different wire packages 1. After the angle fans 52 are installed on the through holes three, the angles need to be adjusted so that the angle fans 52 at different positions can completely blow the cold air into the interior of the wire package 1. At both ends of the C-shaped long steel, the angle between the bottom of the two angle fans 52 and the bottom of the C-shaped long steel is α, 0°≤α≤90°.

[0039] Each strip-shaped slot 54 is clamped with the corresponding through hole three by the corresponding bolt and nut one. After tightening the nut one until the C-shaped long steel is clamped, the angle and height of the angle fan 52 are fixed. When the angle or height needs to be fine-tuned, loosen the nut one, rotate the angle fan 52 to the appropriate angle, and then tighten the nut one. Each through hole one is clamped with the corresponding through hole two by the corresponding bolt and nut one. A part of the through holes two is clamped to the top of the fixing plate 6 by the corresponding bolt and nut one. The parallel fan 51 is fixed to the C-shaped short steel by the bolt and nut one respectively, and then the C-shaped short steel and two of the C-shaped long steels are fixed to the fixing plate 6, and the angle fan 52 is fixed between the two C-shaped long steels.

The two angle fans 52 can adjust their angles α with the horizontal direction according to actual needs. The angles α can be consistent or inconsistent. Each line package is surrounded by two parallel fans 51 and one angle fan 52.

[0044] 3. The parallel fan 51 and the angle fan 52 blow cold air from the bottom of the wire package into the interior of the coil 11, and then the cold air travels through the air duct to various parts of the coil 11, taking the heat on the coil 11 out from the top.
