Example Embodiment

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Such as figure 1 , figure 2 , image 3 As shown, the embodiment of the present invention provides a dry-type transformer, including a transformer body 1, a cover 2, a bottom plate 3, and a fan 4. The transformer body 1 is composed of multiple sets of encapsulated winding arrays and generally selects 3 sets of arrays, and the transformer The bottom of the body 1 is provided with a supporting rod 11, which connects each group of encapsulated windings to each other, and the supporting rods 11 are arranged in a cross, so that the supporting rod 11 as a whole is sufficient to support the transformer body 1, and the supporting rod 11 penetrates A threaded hole 101.

[0029] Such as Figure 4 , 5 As shown, the bottom of the casing 2 has an open cavity structure, and the outer walls on both sides of the casing 2 are symmetrically provided with convex edges 21 protruding outward. The protrusions 21 are made of graphite and are integrally formed with the outer walls on both sides of the casing 2. It is distributed in an array along the outer walls on both sides of the casing 2. Vent holes 201 are distributed along the convex edge 21 and the outer wall on both sides of the casing 2. The ventilation holes 201 on the outer wall of the casing 2 communicate with the inner cavity. 2 The two sides of the bottom of the housing 2 are symmetrically provided with a positioning groove 22 along the array direction of the convex edge 21.

[0030] Such as Image 6 As shown, the surface of the bottom plate 3 is provided with a second threaded hole 301, and symmetrical clamping strips 31 are provided on both sides of the bottom plate. The clamping strips 31 are locked and fixed with the limiting groove 22, and the bottom plate 3 completely covers the cover. At the bottom of the shell 2, the second threaded hole 301 can also provide ventilation and heat dissipation.

[0031] The first threaded hole 101 on the strut 11 at the bottom of the transformer body 1 and the second threaded hole 301 on the surface of the bottom plate 3 are fastened by bolts, and the second threaded holes 301 are evenly distributed. Adjust the first threaded holes appropriately according to the location requirements. In the connection position relationship between 101 and the second threaded hole 301, the transformer body 1 is placed in the cavity of the casing 2 as a whole to prevent the bottom plate 3 from shaking when being fixed.

[0032] The upper surface of the limiting groove 22 is evenly distributed with locking bolts 221. The locking bolts 221 pass through the bottom of the casing 2 and the second threaded holes 301 on the surface of the bottom plate 3 at the same time. The diameters of the locking bolts 221 are larger than the middle diameter at both ends The bolt-like structure can effectively realize the fixed connection between the bottom plate 3 and the cover 2.

[0033] Such as Figure 7 As shown, the fan 4 includes a wind hood 41 and a wind blade 42 arranged at the bottom of the outer casing 41. The wind hood 41 has a circular structure as a whole with a cavity in the middle. The outer wall where the wind hood 41 is located is a hollow structure. It is fixedly connected to the top of the cavity structure of the casing 2. The top of the fan 4 provides power supply through a power connection line, and the power connection line runs through the top of the casing 2 to communicate with an external power source.

[0034] When in use, the fan 4 can effectively realize air circulation in the cavity of the casing 2 and avoid damage to the transformer body 1 caused by excessive local temperature. At the same time, the ventilation holes 201 on the outer wall of the casing 2 communicate with the internal cavity to effectively dissipate heat, and the array of protrusions 21 can effectively absorb the heat emitted through the ventilation holes 201 on the outer wall of the casing 2, and The purpose of rapid cooling can be achieved, and the protrusions 21 are relatively densely distributed, and the adjacent protrusions 21 are also provided with vent holes 201 to attach external dust, so as to avoid entering the interior through the outer wall of the casing 2 and causing Damage to the transformer body 1.
