Description

Technical Field

[0001] The utility model relates to the technical field of transformers, and in particular to a short-circuit resistant transformer. Background Art

[0002] A transformer is an electrical device used to change the voltage of alternating current (AC). It converts high-voltage input current into low-voltage current through the principle of electromagnetic induction. Transformers primarily consist of two windings (primary and secondary) and an iron core. They are widely used in power transmission and distribution systems and various electronic devices to improve energy efficiency and reduce energy loss.

[0003] In order to improve the heat dissipation capacity of the existing transformer, a heat sink is provided on the outside of the transformer to increase the heat dissipation area to improve the heat dissipation efficiency of the transformer.

[0004] Although this can achieve heat dissipation for the transformer, the following problems still exist: relying solely on the heat sink for natural heat dissipation may still result in the temperature inside the transformer not being able to be quickly discharged, causing the temperature of the transformer's internal winding to be too high and causing the transformer to short-circuit. Utility Model Content

[0005] The utility model provides an anti-short-circuit transformer, which solves the problem of insufficient heat dissipation of the transformer in the prior art and improves the practicability of the equipment.

Then start the transmission belt and the fan. Through the movement of the transmission belt, drive the connecting member to move, so that the connecting member moves in the sliding groove to drive the transportation member to make up-and-down reciprocating movements on the first sliding rail and the second sliding rail, so that the fan cools the gap between the heat dissipation plates.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 2 to 6 As shown, this embodiment provides a short-circuit-resistant transformer, which includes a housing 1. In this embodiment, the side walls of the housing 1 are provided with a plurality of heat dissipation structures for dissipating heat from the housing 1. A fan 6 is also provided on one side of each heat dissipation structure. Furthermore, a transport structure for transporting the fan 6 and cooling all the heat dissipation structures is provided on the side walls of the housing 1. The bottom of the housing 1 is provided with a plurality of support legs 4, each of which is provided with an adjustment structure for adjusting the extension length of the support leg 4. In this embodiment, a water cooling pipe can be provided at the air outlet of the fan 6 to reduce the temperature of the air blown by the fan 6, thereby dissipating heat from the housing 1 more quickly.

[0029] The adjustment structure in this embodiment includes an adjustment bolt 42. A plurality of mounting members 3 are fixed to the bottom of the box body 1. The cross-section of each mounting member 3 is a "冂"-shaped structure. Sliding holes 31 are provided at both ends of each mounting member 3. A second sliding rod 41 is provided at the top of the support foot 4. The second sliding rod 41 is slidably connected to the sliding hole 31. The adjustment bolt 42 is threadedly connected to the second sliding rod 41. The adjustment bolt 42 is disposed at the lower end of the connecting member 83 and abuts against the top of the mounting member 3. By rotating the adjustment bolt 42, the extension length of the support foot 4 is controlled, so that the box body 1 remains horizontal during installation, preventing the phenomenon of unstable center of gravity of the box body 1 and effectively preventing the box body 1 from sliding.

[0030] The heat dissipation structure in this embodiment includes a plurality of heat dissipation fins 2. Each heat dissipation fin 2 is parallel to the side walls on both sides of the box body 1. Bolt holes 221 are provided at both ends of each heat dissipation fin 2 for installing and fixing the heat dissipation fin 2 to the box body 1. Each heat dissipation fin 2 is connected and fixed to the side wall of the box body 1 through the bolt holes 221. A gap is provided between each adjacent heat dissipation fin 2. In this embodiment, a heat conducting member can be provided on the heat dissipation fin 2 to connect the heat conducting member to the insulating oil inside the box body 1. The heat in the insulating oil inside the box body 1 is conducted to the heat dissipation fin 2 through the heat conducting member. Such a design is to allow the wind blown by the fan 6 to pass through the gaps between the heat dissipation fins 2, and the temperature of the heat dissipation fin 2 is reduced more quickly through the flowing air, improving the heat dissipation efficiency of the heat dissipation fin 2.

[0031] The heat dissipation fin 2 in this embodiment includes a heat dissipation portion 21 and a connecting portion 22. The heat dissipation portion 21 is a rectangular structure to increase the area of the heat dissipation portion 21 and improve the heat dissipation efficiency. The connecting portion 22 is an isosceles triangle structure to minimize the volume of the connecting portion 22 and save manufacturing costs. The bolt hole 221 is provided at the end of the connecting portion 22 away from the heat dissipation portion 21. The thickness of the connecting portion 22 is greater than the thickness of the heat dissipation portion 21 to generate a gap between each heat dissipation fin 2, facilitating the airflow blown by the fan to pass through. In this embodiment, a plurality of heat dissipation blocks can be provided on the side walls on both sides of the heat dissipation portion 21. The cross-section of the heat dissipation block is an isosceles triangle structure, and the heat dissipation efficiency of the heat dissipation fin 2 is improved by increasing the heat dissipation area of the heat dissipation fin 2.

[0032] The transportation structure in this embodiment includes a transportation member 7. A mounting plate 5 is fixed to the side wall of the box body 1. A transmission belt 8 is rotatably connected to the mounting plate 5. A connecting member 83 is provided on the transmission belt 8. The fan 6 is fixedly connected to the transportation member 7. In this embodiment, the fan 6 is moved up and down reciprocally by the transmission belt 8, so that the fan 6 can continuously move, ensuring that uniform cooling and heat dissipation can be achieved at each position on the heat dissipation plate.

[0033] In this embodiment, the mounting plate 5 is secured to both sides with a first sliding rail 51 and a second sliding rail 52, which serve to restrict the movement of the transport member 7 and prevent it from slipping or shifting during movement. The transport member 7 is provided with a sliding groove 71, to which a connecting member 83 is slidably connected. The transport member 7 is slidably connected to both the first and second sliding rails 51 and 52. The sliding direction of the transport member 7 on the first sliding rail 51 is perpendicular to the sliding direction of the connecting member 83 on the sliding groove 71. This design ensures that the transport member 7 only performs up and down reciprocating motion and does not slip or shift left or right during movement.

[0034] In this embodiment, the connecting member 83 is provided with a first sliding rod 82, which is slidably connected to the sliding groove 71. A limit bolt 81 is fixed to the end of the first sliding rod 82, and the limit bolt 81 abuts against the sliding groove 71. This design ensures that the transport member 7 can stably reciprocate up and down under the drive belt 8, thereby improving the stability of the structure.

[0035] The working process of this embodiment is as follows: first, the box body 1 is transported to the designated installation position, and then the box body 1 is kept balanced by rotating the adjusting bolt 42, and then the transmission belt 8 and the fan are turned on, and the movement of the transmission belt 8 drives the connecting member 83 to move, so that the connecting member 83 moves in the sliding groove 71 and drives the transport member 7 to move up and down on the first sliding rail 51 and the second sliding rail 52, so that the fan cools the gap between the heat sinks.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
