The working principle of a transformer is based on the electromagnetic induction phenomenon of "electricity generates magnetism, and magnetism generates electricity," and it is a very common device today.
[0003] Due to the nature of their operation, transformers are widely used in industries, agriculture, transportation, and urban communities. When a transformer is in operation, it is equipped with a variety of electrical components. During operation, the transformer generates a lot of heat. If heat is not dissipated in time, the internal temperature of the transformer will rise, which will affect its normal operation and lifespan, and may directly damage the transformer. Utility Model Content

If the heat is not dissipated in time, the internal temperature of the transformer will rise, which will affect its normal operation and lifespan, and may also directly damage the transformer.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a transformer with overheat protection, comprising a wind box, an outer casing, a transformer body, and a support plate. A first motor is installed at the top of the wind box, and a fan blade is connected to the output end of the first motor. A filter plate is installed inside the wind box, and a filter screen layer is arranged inside the top of the outer casing. A cooling water roller is assembled at the upper position inside the outer casing. An inlet is connected to the left side of the cooling water roller, and an outlet is connected to the right side of the cooling water roller. Distribution plates are provided at both the upper and lower positions of the cooling water roller. The distribution plates have reserved holes inside, and concave grooves are formed on the end faces of the distribution plates.

[0007] As a further technical solution of this utility model, the water inlet is interconnected with the cooling water roller, and the water outlet is interconnected with the cooling water roller.
[0008] As a further technical solution of this utility model, temperature sensors are installed at the upper and lower positions on both sides of the inner wall of the outer casing, and a heat-conducting rod is connected to the outer position of the transformer body, with the tail end of the heat-conducting rod contacting the inner wall of the outer casing.
[0009] As a further technical solution of this utility model, valves are installed in both the water outlet and the water inlet, and the outer walls of the air box and the first motor are coated with a shielding layer.
[0010] As a further technical solution of this utility model, the bottom of the support plate is fixed with support legs, and the support legs are symmetrically distributed about the central axis of the support plate.

A circular filter plate is installed on the side of the arc-shaped plate, and a connecting bolt is installed between the arc-shaped plate and the connecting bolt.
[0013] Compared with the prior art, the beneficial effects of this utility model are: this transformer with overheat protection not only improves the heat dissipation protection capability, but also improves the exhaust filtration capability and bottom support capability of the transformer.
[0014] (1) By arranging the filter layer in the middle of the top of the outer casing, and then arranging the cooling water roller in the upper part of the outer casing, the water inlet is connected to the left side and the water outlet is connected to the right side. The flow distribution plate is installed and fixed inside the outer casing, and the two flow distribution plates are distributed above and below the cooling water roller. Therefore, after the first motor works, it can drive the fan blade to rotate. The airflow flows through the filter plate and then through the filter layer to flow into the outer casing. At this time, the airflow is evenly distributed through the reserved hole, and the airflow reaches the outer casing after being cooled by the cooling water roller. This plays a certain role in heat dissipation. After working together with the heat conduction rod, the overall overheat protection capability is improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 An embodiment of this utility model provides a transformer with overheat protection, including a bellows 1, an outer casing 7, a transformer body 9, and a support plate 11. A first motor 3 is installed at the top of the bellows 1, and a fan blade 2 is connected to the output end of the first motor 3. A filter plate 4 is installed inside the bellows 1. A filter screen layer 5 is arranged inside the top of the outer casing 7. A cooling water roller 12 is installed at the upper position inside the outer casing 7. A water inlet 13 is connected to the left side of the cooling water roller 12, and a water outlet 6 is connected to the right side of the cooling water roller 12. A flow distribution plate 14 is provided at both the upper and lower positions of the cooling water roller 12. A reserved hole 15 is opened inside the flow distribution plate 14, and a concave groove 16 is formed on the end face of the flow distribution plate 14.
[0024] The flow distribution plate 14 is symmetrically distributed about the central axis of the cooling water roller 12, and the reserved holes 15 are evenly distributed within the flow distribution plate 14.
[0025] The inlet 13 is connected to the cooling water roller 12, and the outlet 6 is connected to the cooling water roller 12.
[0026] Temperature sensors are installed on the upper and lower positions of both sides of the inner wall of the outer casing 7. A heat-conducting rod 8 is connected to the outer position of the transformer body 9, and the tail end of the heat-conducting rod 8 is in contact with the inner wall of the outer casing 7.
[0027] Valves are installed in both the outlet 6 and the inlet 13, and the outer walls of the air box 1 and the first motor 3 are coated with a shielding layer.
[0028] Support legs 20 are fixed to the bottom of the support plate 11, and the support legs 20 are symmetrically distributed about the central axis of the support plate 11.
[0029] An insulating adhesive layer 22 is fixed at the middle position of the bottom of the support plate 11, and an insulating pad 21 is adhered to the outer side wall of the bottom of the insulating adhesive layer 22.
[0030] An exhaust pipe 10 is installed on the lower right side of the outer casing 7. An arc-shaped plate 17 is fixed on the upper and lower parts of the inner wall of the exhaust pipe 10. A circular filter plate 19 is installed on the side of the arc-shaped plate 17. A connecting bolt 18 is installed between the arc-shaped plate 17 and the connecting bolt 18.
[0031] Furthermore, valves are provided in the exhaust pipe 10, the outlet 6 and the inlet 13 to facilitate the opening and closing of the flow rate;
[0032] Furthermore, the end face of the flow distribution plate 14 is formed with a concave groove 16. Two concave grooves 16 are distributed opposite each other at the upper and lower positions of the cooling water roller 12. Therefore, the curvature of the concave groove 16 is greater than that of the concave groove 16.
[0033] Working principle: First, during operation, the support legs 20 are fixed to both sides of the bottom of the support plate 11. At the same time, the insulating pad 21 is bonded and fixed to the middle of the bottom of the support plate 11 using an insulating adhesive layer 22. Thus, when in contact with the ground, the support legs 20 provide bottom support, and the insulating pad 21 provides bottom insulation protection. The cooling water roller 12 is arranged in the upper position inside the outer casing 7. The left side is connected to the water inlet 13, and the right side is connected to the water outlet 6. The flow distribution plate 14 is installed and fixed inside the outer casing 7, and the two flow distribution plates 14 are distributed above and below the cooling water roller 12. Therefore, after the first motor 3 starts working, it can drive the fan blade 2 to rotate. The airflow flows through the filter plate 4 and then through the filter screen layer 5 before flowing into the outer casing 7. At this time, the airflow is evenly distributed through the reserved hole 15. After the airflow is cooled by the cooling water roller 12, it reaches the outer casing 7. When exhausting, the exhaust pipe 10 is used for exhaust.
