[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0029] As a preferred embodiment, a cooling box 15 is provided on one side of the side panel 2, both ends of the cooling copper tube 14 pass through the outer wall of the base 1 and are connected to the cooling box 15, and a water pump 16 is provided on one side of the cooling copper tube 14; further, the coolant in the cooling box 15 can be pumped into the cooling copper tube 14 through the water pump 16 for reciprocating flow, thereby achieving heat dissipation of the transformer.

[0030] As a preferred embodiment, the inner walls of the two sets of side panels 2 are provided with temperature sensors 17, and a controller 18 is provided on one side of the cooling box 15. The controller 18 is connected to the temperature sensor 17, the water pump 16 and the cooling fan 10 by wires; further, the temperature sensor 17 can detect the temperature change of the transformer. When the transformer temperature exceeds a certain set value, the temperature sensor 17 can transmit a signal to the controller 18, and the controller 18 controls the water pump 16 and the cooling fan 10 to start cooling it, thereby achieving the effect of active and efficient heat dissipation.

[0031] As a preferred embodiment, through slots 19 are arranged at the four end edges of the base 1, a movable column 20 is provided through the middle of the through slot 19, and the top of the movable column 20 is connected to a limiting block 21; further, the movable column 20 can move in the through slot 19.

[0032] As a preferred embodiment, the end of the movable column 20 away from the limit block 21 is connected to a support foot 22 through the through slot 19, and the top of the support foot 22 is connected to a support spring 23, and the support spring 23 is sleeved on the outer wall of the movable column 20, and the end of the support spring 23 away from the support foot 22 is in contact with the base 1; further, the support foot 22 plays a supporting and fixing role, and through holes are provided on both sides of the support foot 22 for installation and fixing, and the support spring 23 plays a buffering role and shrinks and rebounds under pressure.

[0033] As a preferred embodiment, the inner wall of the through groove 19 is provided with a movable groove 24, and the middle outer wall of the movable column 20 is connected to the damping ring 25, and the outer wall of the damping ring 25 abuts against the inner wall of the movable groove 24; further, the vibration generated by the operation of the transformer will push the base 1 to move downward under pressure, thereby squeezing the support spring 23. The support spring 23 can provide a certain buffering for the support foot 22 to prevent the vibration from being transmitted to the bottom of the support foot 22. After buffering, the rebound force of the support spring 23 pushes the base 1 upward, thereby preventing the vibration from being transmitted to the support foot 22 and the foundation. The friction between the inner wall of the movable groove 24 and the damping ring 25 generates a certain damping, thereby offsetting the impact caused by the rebound of the support spring 23 after being compressed, thereby performing vibration isolation treatment between the transformer and the support foot 22, thereby reducing the noise transmitted to the surrounding environment by the transformer through the foundation, so as to reduce the noise pollution caused by the operation of the equipment.

[0034] The working process of the utility model is as follows: first, by twisting the adjusting knob 6, the threaded rod 4 can be driven to rotate, and the threaded rod 4 rotates in the threaded barrel 3 to rotate and lift, and at the same time drives the top plate 5 to lift synchronously, thereby realizing the lifting and adjusting function of the top plate 5. At the same time, the limit rod 8 plays a limiting role during the lifting process, so that the top plate 5 can be lifted and lowered smoothly, so that it can be adjusted when installing transformer cores of different specifications. The transformer core can be installed and fixed by the core fixing seat 11. The heat dissipation fan 10 can be used to cool the transformer that generates heat during operation. At the same time, when the transformer is heated, the heat can be conducted to the surface of the heat conducting plate 13. The heat conducting plate 13 is cooled and exchanged through the cooling copper tube 14, thereby improving the heat dissipation effect of the transformer. The temperature change of the transformer can be detected by the temperature sensor 17. When the transformer temperature exceeds a certain set value, the temperature sensor 17 can transmit a signal to the controller 18. The controller 18 controls the water pump 16 and the heat dissipation fan 10 to start the heat dissipation work, thereby The function of active and efficient heat dissipation is realized. When the transformer is working or the heat dissipation fan 10 is working, vibration will be generated, thereby emitting noise. Among the noise influences of the transformer in the distribution room, structural noise, especially the structural noise generated by the ground transmission, is the main pollution source. The vibration generated by the operation of the transformer will push the base 1 to move downward under pressure, thereby squeezing the support spring 23. The support spring 23 can provide a certain buffering for the support foot 22 to prevent the vibration from being transmitted to the bottom of the support foot 22. After buffering, the rebound force of the support spring 23 pushes the base 1 upward, thereby preventing the vibration from being transmitted to the support foot 22 and the foundation. The friction between the inner wall of the movable groove 24 and the damping ring 25 generates a certain damping, thereby offsetting the impact caused by the rebound of the support spring 23 after being compressed, thereby performing vibration isolation treatment between the transformer and the support foot 22, realizing the vibration isolation function between the transformer and the ground, thereby reducing the noise transmitted to the surrounding environment by the transformer through the foundation, so as to reduce the noise pollution caused by the operation of the equipment. The above is the working principle of this transformer frame with efficient heat dissipation.
