DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 4 A dry-type transformer is used in the field of transformers, comprising: a dry-type transformer 1, and a protective frame for protecting the dry-type transformer, the protective frame consisting of two bases 2, a first air guide cover 7 and a second air guide cover 8, the base 2 is fixedly arranged at the bottom of the dry-type transformer 1, and the first air guide cover 7 and the second air guide cover 8 are detachably installed on the top of the two bases 2, together forming protection for the dry-type transformer 1.

[0032] In order to fix the two air guide covers, the present specific embodiment provides two connecting plates 4, which are respectively arranged on both sides of the first air guide cover 7. These connecting plates 4 are not only used to fix the air guide covers, but also have blowers 5 and exhaust fans 10 arranged thereon. One end of the blower 5 extends into the first air guide cover 7, and one end of the exhaust fan 10 extends into the second air guide cover 8. Such a design can speed up the air flow between the first air guide cover 7 and the second air guide cover 8, thereby improving the heat dissipation effect.

[0033] In order to realize intelligent control of the blower 5 and the exhaust fan 10, a controller 6 is fixedly provided on one side of the connecting plate 4. The blower 5 and the exhaust fan 10 are connected to the controller 6 through wires, so that the controller 6 can automatically adjust the working states of the blower 5 and the exhaust fan 10 according to conditions such as temperature. The controller 6 adopts the LD-B10-10G (B) dry-type transformer temperature controller.

[0034] In addition, in order to provide support for the first air guide cover 7 and the second air guide cover 8 and fix the connecting plate 4, this specific embodiment also designs a supporting mechanism, which is arranged between the first air guide cover 7 and the second air guide cover 8 to ensure the stability of the structure and the heat dissipation effect.

[0035] Furthermore, two positioning columns 20 are fixedly provided on the top of the base 2, and these positioning columns 20 are used to cooperate with the support frame 3. The support frame 3 is inserted into the outer wall of the positioning columns 20, and the first air deflector 7 and the second air deflector 8 are respectively fixedly connected to the two support frames 3 on the same side. Such a design not only realizes the positioning support of the air deflector, but also improves the stability of the overall structure.

[0036] In order to facilitate the installation and fixation of the support frame 3, an insertion rod 14 corresponding to the positioning column 20 is fixed on one side of the connecting plate 4, and a socket 17 compatible with the insertion rod 14 is opened on the outer side of the positioning column 20. During installation, the insertion rod 14 can be inserted into the socket 17 and work together with the base 2 to limit the support frame 3.

[0037] The specific implementation method of the support mechanism is as follows: two plug plates 9 are arranged between the first air deflector 7 and the second air deflector 8, and two slots 11 are provided on the mutually close sides of the first air deflector 7 and the second air deflector 8, and plug strips 16 are inserted into these slots 11, and the two plug strips 16 on the same side are fixedly connected to the corresponding plug plates 9, thereby achieving support for the air deflector.

[0038] In addition, at least two bolts 12 are penetrated on one side of the connecting plate 4, and threaded holes 13 corresponding to the bolts 12 are opened on the outer side of the plug plate 9. During installation, the bolts 12 can be screwed into the threaded holes 13 to fix the connecting plate 4 on the plug plate 9. At the same time, one end of the blower 5 and the exhaust fan 10 extends to the mounting holes of the first air guide cover 7 and the second air guide cover 8, which not only realizes the heat dissipation function, but also limits the connecting plate 4.

[0039] In order to improve the fixing effect of the support frame 3, a second positioning block 18 is fixedly provided on the top of the support frame 3, and a first positioning block 15 used in conjunction with the second positioning block 18 is fixedly provided on the outer wall of the insertion rod 14, and a bevel 19 is provided on the side where the first positioning block 15 and the second positioning block 18 are close to each other. During the installation process, the bevels 19 on the side where the first positioning block 15 and the second positioning block 18 are close to each other can push each other, making it easier for the support frame 3 to fit on the base 2, thereby achieving a better fixing effect.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the blower 5, controller 6 and exhaust fan 10 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
