[0025] A transformer with good heat dissipation performance comprises a transformer body 1 with side grooves, a ventilation frame 2 is fixedly connected to the side of the transformer body 1, a ventilation groove 3 with a dustproof net is provided on the side of the ventilation frame 2, a fixing frame 4 is fixedly connected to the bottom of the ventilation frame 2, a driving motor 5 is fixedly installed on the inner wall of the fixing frame 4, a bidirectional threaded rod 6 is fixedly connected to the output end of the driving motor 5, different thread surfaces of the bidirectional threaded rod 6 are respectively threadedly connected with matching threaded sleeves 7, the surface of the threaded sleeve 7 is connected with a limiting component, a fan 8 is fixedly installed on the side of the threaded sleeve 7, a plug-in board 9 is fixedly connected to the left side of the ventilation frame 2 near its inner wall, a temperature sensor 10 and a humidity sensor 11 are clamped on the inner wall of the plug-in board 9, a resistance heating net 12 is fixedly installed on the surface of the inner wall of the ventilation frame 2, a locking component is connected to the surface of one side of the ventilation frame 2, an arc-shaped dust cover 13 is connected to the surface of the locking component, and the inner wall of the arc-shaped dust cover 13 is sleeved on the outer side of the ventilation groove 3.

[0026] Specifically, Figure 1-Figure 5 As shown, there are two ventilation frames 2 , and the two ventilation frames 2 are respectively fixedly connected to the sides of the transformer body 1 . The two ventilation frames 2 can perform left and right ventilation and heat dissipation processing inside the transformer body 1 .

[0027] Specifically, Figure 1-Figure 5As shown, the limiting assembly includes a limiting plate 14 and a limiting groove 15, wherein the limiting plate 14 is fixedly connected to the side of the threaded sleeve 7, and the limiting groove 15 is provided on the side of the inner wall of the ventilation frame 2, and the inner wall of the limiting groove 15 and the surface of the limiting plate 14 are slidably connected. By setting the limiting plate 14 and the limiting groove 15, the movement trajectory of the threaded sleeve 7 is limited, so that the operation of the bidirectional threaded rod 6 can drive the different threaded sleeves 7 thereon to move.

[0028] Furthermore, the locking assembly includes a magnetic locking plate 18 and a magnetic locking groove 19, the magnetic locking plate 18 is fixedly connected to the side of the arc-shaped dust cover 13, and the magnetic locking groove 19 is opened on the surface of one side of the ventilation frame 2, and the inner wall of the magnetic locking groove 19 and the surface of the magnetic locking plate 18 are magnetically engaged.

[0029] Example 2 Please refer to Figure 1-Figure 5 The difference between this embodiment and embodiment 1 is that the upper threaded sleeve 7 is fixedly connected with a proximity sensor 16, and the lower threaded sleeve 7 is fixedly connected with a light sensing plate 17, and the light sensing plate 17 is located directly below the proximity sensor 16.

Through the setting of the limiting plate 14 and the limiting groove 15, the movement trajectory of the threaded sleeve 7 is limited, so that the operation of the bidirectional threaded rod 6 can drive the different threaded sleeves 7 thereon to move, and because the threaded surfaces at both ends of the bidirectional threaded rod 6 are in opposite directions, the two threaded sleeves 7 can move in opposite directions, thereby driving the fan 8 thereon to move and blow air, so that the smaller fan 8 can perform continuous air exchange to complete the ventilation operation inside the transformer body 1, and the blowing force is controlled according to the temperature sensor 10 and the humidity sensor 11 installed on the side of the ventilation frame 2, as well as the subsequent resistance The heating network 12 is turned on to supply heat, thereby controlling the heat dissipation and cooling inside the transformer body 1 and the hot air dehumidification. Because proximity sensors 16 and light sensors are added to the upper and lower threaded sleeves 7, the two fans 8 are prevented from being too close to each other and touching and being damaged, and then the subsequent drive motor 5 is operated to control the repeated lifting and lowering of the two fans 8 to expand the blowing range and activate the wind force. Because an arc-shaped dust cover 13 is added to the side of the ventilation frame 2, unexpected situations such as external rain and strong wind can be avoided, and a dust-proof mesh plate 20 is added below the arc-shaped dust cover 13 to block dust during the ventilation process. Through the arrangement of the magnetic locking plate 18 and the magnetic locking groove 19, the subsequent replacement and cleaning of the arc-shaped dust cover 13 can be carried out, ensuring the ventilation and heat dissipation effect under the dust and rainproof external protection state inside the transformer under normal conditions.
