Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation devices for dry-type transformers, and in particular to a heat dissipation structure for dry-type transformers. Background Technology

[0002] Generally, a dry-type transformer refers to a transformer whose core and windings are not immersed in insulating oil. It mainly consists of a silicon steel core and epoxy resin-cast coils. An insulating cylinder is placed between the high-voltage and low-voltage coils to increase electrical insulation, and spacers support and constrain the coils. All fasteners connecting the components have anti-loosening properties. Dry-type transformers can experience excessive loads during operation, causing significant heat generation in both the high-voltage and low-voltage coils; therefore, cooling measures are necessary for both types of transformers.

[0003] For example, Chinese patent application CN202220632194.7 discloses a dry-type transformer with a high-efficiency heat dissipation structure. Specifically, a heat dissipation box is fixedly connected to the bottom of the dry-type transformer body, a fan is fixedly connected to the inner bottom wall of the heat dissipation box, side exhaust fan blades are fixedly connected to the front of the heat dissipation box, and an upper exhaust vent is opened on the top of the heat dissipation box. However, it has the following technical problems:

[0004] Dry-type transformers come in a variety of models and sizes, resulting in different sizes of dry-type transformers. However, the heat dissipation box that is fixedly installed at the bottom of the dry-type transformer in the existing technology is not adaptable to dry-type transformers of different sizes, making it difficult to adjust according to different sizes of dry-type transformers. Utility Model Content

[0005] To address the problem mentioned in the background art that the heat dissipation box is difficult to adapt to dry-type transformers of different sizes, this utility model provides the following technical solution:

[0006] A heat dissipation structure for a dry-type transformer includes a heat dissipation structure one and a heat dissipation structure two for dissipating heat from the body of the dry-type transformer.

[0007] The heat dissipation structure includes a support base plate, the upper end of which is machined with multiple threaded holes to facilitate fixing dry-type transformer bodies of different sizes.

[0008] A first heat dissipation component is installed in the middle of the support base plate, and second heat dissipation components are installed at both ends of the support base plate to cooperate with the first heat dissipation component to dissipate heat from the dry-type transformer body. A reciprocating screw is installed in the middle of the support base plate to control the two second heat dissipation components to move in opposite directions.

[0009] The second heat dissipation structure includes a third heat dissipation component and an adjustment box. The adjustment box includes a fourth heat dissipation component for dissipating heat from the upper end of the dry-type transformer body. The second heat dissipation structure includes a reciprocating screw for controlling the two adjustment boxes to move in opposite directions.

[0010] Furthermore, a first support frame is installed at the lower end of the dry-type transformer body, and a second support frame is installed at the lower end of the first support frame.

[0011] Furthermore, a handwheel for controlling the rotation of the reciprocating screw is installed at one end of the reciprocating screw.

[0012] Furthermore, a motor housing is installed at the lower end of the first heat dissipation component, and a bearing seat for limiting the reciprocating lead screw is installed at the lower end of the motor housing. A vertical groove is machined on the inner wall of the middle part of the support base plate, and a T-shaped groove is machined on the upper end of the vertical groove.

[0013] Furthermore, a motor housing is installed at the lower end of the second heat dissipation component, and a lead screw nut is installed at the lower end of the motor housing. Connecting plates are installed at both ends of the second heat dissipation component, and a limiting plate for limiting the connecting plate is installed at one end of the connecting plate, and the limiting plate slides in the cavity of the T-shaped groove.

[0014] Furthermore, a bevel gear one is installed at one end of the third heat dissipation component, and a bevel gear two for controlling the rotation of the bevel gear one is meshed at one end of the bevel gear one. A rotating shaft is installed in the middle of the bevel gear two, and a motor for controlling the rotation of the rotating shaft is installed at one end of the rotating shaft. Sliding grooves are machined at both ends of the rotating shaft.

[0015] Furthermore, a bevel gear three is installed at one end of the fourth heat dissipation component, and a bevel gear four for controlling the rotation of the bevel gear three is meshed at one end of the bevel gear three. A rotating tube is installed in the middle of the bevel gear four, and a limiting block for limiting the rotation of the rotating tube is installed on the inner wall of the rotating tube in conjunction with the sliding groove.

[0016] Furthermore, the regulating box includes a housing for limiting the rotation tube, with limiting bearings installed at both ends of the housing for limiting the rotation tube, and a screw nut two for cooperating with the reciprocating screw two to control the movement of the fourth heat dissipation assembly at one end of the housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By rotating the reciprocating screw one by handwheel, the second heat dissipation component moves left and right according to the different sizes of the dry-type transformer body, adjusting the distance between the two second heat dissipation components. The setting of the first and second heat dissipation components allows air to blow upward from the bottom of the dry-type transformer body, accelerating air circulation and facilitating heat dissipation of the dry-type transformer body.

[0019] Second, when the reciprocating screw two rotates, the distance between the two adjusting boxes is adjusted according to the different sizes of the dry-type transformer body. After the distance between the fourth heat dissipation components is adjusted, the motor is started, and the rotating shaft synchronously drives the bevel gear two and the rotating tube to rotate. The rotating tube, in conjunction with the bevel gear four, drives the bevel gear three to rotate, so that the fans inside the fourth heat dissipation component and the third heat dissipation component blow air onto the upper end of the dry-type transformer body to dissipate heat from the upper end of the dry-type transformer body.

Detailed Implementation

[0034] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0035] Please see Figures 1-7 This utility model provides a heat dissipation structure for a dry-type transformer, including a heat dissipation structure 1001 and a heat dissipation structure 2002 for dissipating heat from the dry-type transformer body 10. A first support frame 11 is fixedly installed at the lower end of the dry-type transformer body 10, and a second support frame 12 is fixedly installed at the lower end of the first support frame 11.

[0036] The heat dissipation structure 1001 includes a support base plate 100, and a second support frame 12 is installed on the upper end of the support base plate 100. The upper end of the support base plate 100 is machined with multiple threaded holes 110 for fixing dry-type transformer bodies 10 of different sizes. A first heat dissipation component 130 is installed in the middle of the support base plate 100, and second heat dissipation components 200 are installed at the left and right ends of the support base plate 100 to cooperate with the first heat dissipation component 130 to dissipate heat from the dry-type transformer body 10.

[0037] A reciprocating screw 120 for controlling the two second heat dissipation components 200 to move in opposite directions is installed in the middle of the support base plate 100. A handwheel 121 for controlling the rotation of the reciprocating screw 120 is installed at one end of the reciprocating screw 120. By rotating the reciprocating screw 120 through the handwheel 121, the second heat dissipation components 200 can move left and right according to the different sizes of the dry-type transformer body 10, thereby adjusting the distance between the two second heat dissipation components 200.

[0038] A motor housing 131 is installed at the lower end of the first heat dissipation component 130. A motor for controlling the rotation of the central fan of the first heat dissipation component 130 is installed inside the motor housing 131. Bearing seats 132 for limiting the reciprocating lead screw 120 are fixedly installed on the left and right sides of the lower end of the motor housing 131. A vertical groove 140 is machined on the inner wall of the middle part of the support base plate 100, and a T-shaped groove 141 is machined on the upper end of the vertical groove 140.

[0039] The lower end of the second heat dissipation component 200 is equipped with a motor housing 210. The lower end of the motor housing 210 is fixedly equipped with a screw nut 211 for cooperating with the reciprocating screw 120 to control the movement of the second heat dissipation component 200. The front and rear ends of the second heat dissipation component 200 are fixedly equipped with connecting plates 220. One end of the connecting plate 220 is fixedly equipped with a limiting plate 221 for limiting the connecting plate 220. The limiting plate 221 slides in the cavity of the T-slot 141, so that the second heat dissipation component 200 moves left and right when the reciprocating screw 120 rotates.

[0040] The arrangement of the first heat dissipation component 130 and the second heat dissipation component 200 allows air to blow upwards from the bottom of the dry-type transformer body 10, accelerating air circulation and facilitating heat dissipation for the dry-type transformer body 10.

[0041] The heat dissipation structure 2002 includes a third heat dissipation component 300 and an adjustment box 500. A bevel gear 310 for controlling the rotation of the fan inside the third heat dissipation component 300 is installed at the front end of the third heat dissipation component 300. A bevel gear 400 for controlling the rotation of the bevel gear 310 is meshed at one end of the bevel gear 310. A rotating shaft 410 is fixedly installed in the middle of the bevel gear 400. A motor 411 for controlling the rotation of the rotating shaft 410 is installed at the left end of the rotating shaft 410. Sliding grooves 412 are machined at both ends of the rotating shaft 410. When the motor 411 is started, the rotating shaft 410 drives the bevel gear 400 to rotate, so that the bevel gear 310 synchronously drives the fan inside the third heat dissipation component 300 to blow air onto the upper end of the dry-type transformer body 10.

[0042] The regulating box 500 includes a fourth heat dissipation assembly 510 for dissipating heat from the upper end of the dry-type transformer body 10. A bevel gear 3 511 is installed at the front end of the fourth heat dissipation assembly 510. One end of the bevel gear 3 511 is meshed with a bevel gear 4 520 for controlling the rotation of the bevel gear 3 511. A rotating tube 521 is fixedly installed in the middle of the bevel gear 4 520 and is sleeved on the rod of the rotating shaft 410. A limiting block 522 is fixedly installed on the inner wall of the rotating tube 521 for limiting the rotating tube 521 in conjunction with the sliding groove 412, so that when the rotating shaft 410 rotates, the rotating tube 521 rotates synchronously, and the bevel gear 4 520 drives the bevel gear 3 511 to rotate.

[0043] The regulating box 500 includes a box body 530 for limiting the rotation tube 521. Limit bearings 531 for limiting the rotation tube 521 are installed at both ends of the box body 530. A screw nut 532 for cooperating with the reciprocating screw 600 to control the movement of the fourth heat dissipation assembly 510 is fixedly installed at the front end of the box body 530.

[0044] The heat dissipation structure 2002 includes a reciprocating screw 2600 for controlling the two regulating boxes 500 to move in opposite directions. A handwheel is installed at the right end of the reciprocating screw 2600. By rotating the handwheel at the right end of the reciprocating screw 2600, the reciprocating screw 2600, in conjunction with the screw nut 2532, controls the box 530, the bevel gear 420, and the fourth heat dissipation component 510 to slide on the rod of the rotating shaft 410, so as to adjust the distance between the two fourth heat dissipation components 510 according to the different sizes of the dry-type transformer body 10.

[0045] After the spacing between the fourth heat dissipation components 510 is adjusted, the motor 411 is started. The rotating shaft 410 synchronously drives the second bevel gear 400 and the rotating tube 521 to rotate. The rotating tube 521, in conjunction with the fourth bevel gear 520, drives the third bevel gear 511 to rotate, so that the fans inside the fourth heat dissipation component 510 and the third heat dissipation component 300 blow air onto the upper end of the dry-type transformer body 10 to dissipate heat from the upper end of the dry-type transformer body 10. The airflow from the first heat dissipation component 130 and the second heat dissipation component 200 to the upper end of the dry-type transformer body 10 will gradually weaken, making it difficult for the heat at the upper end of the dry-type transformer body 10 to dissipate quickly. Through the arrangement of the third heat dissipation component 300 and the fourth heat dissipation component 510, the upper end of the dry-type transformer body 10 is quickly cooled.

[0046] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
