The rotation of the adjusting tube 26 drives the adjusting push block 27 to rotate synchronously, and the adjusting push block 27 plays the role of supporting the supporting spring 25. The limiting cavity 24 plays a limiting role so that the top of the connecting tube 19 abuts against the supporting spring 25, so that it can perform synchronous lifting and lowering movements with the supporting spring 25.

[0037] As a preferred embodiment, the inner wall of the adjusting push block 27 is provided with an internal thread 271, and the internal thread 271 is threadedly connected to the external thread 201.

The iron core 11 of the transformer is composed of silicon steel sheets. Under the action of the electromagnetic field, the silicon steel sheets will undergo magnetostriction, that is, the size along the direction of the magnetic lines of force will change, and the excitation disappears. After that, the silicon steel sheet returns to its original shape. This periodic expansion and contraction change will cause the vibration of the iron core 11, thereby driving the overall vibration of the transformer and generating noise. When the transformer vibrates, it drives the connecting tube 19 to vibrate slightly synchronously.

At the same time, cooling water can be stored in the heat exchange water tank 33, and the heat exchange effect of the cooling oil is achieved through the heat exchange pipe 31 in the heat exchange water tank 33, so as to improve the heat dissipation effect of the transformer and increase the service life of the transformer.

[0042] The working process of the present application is as follows: first, when installing the iron core 11, it can be embedded in the limiting clamping groove 5 on the top of the lower clamping piece 3, and the twisting adjustment knob 8 drives the screw rod 6 to rotate synchronously. The rotation of the screw rod 6 drives the moving block 7 to move downward, and the movement of the moving block 7 drives the upper clamping piece 4 to move synchronously, so that the limiting clamping groove 5 on the inner wall of the upper clamping piece 4 can be used to fit the lower clamping piece 3 for extrusion, clamping and fixing, thereby realizing the fixation of the iron core 11. When disassembly is required, the adjusting knob 8 can be twisted in the opposite direction to disassemble the iron core 11. The guide rod 9 and the sliding ring 10 play a limiting role to prevent the upper clamping piece 4 from rotating at will. The segmented winding method is adopted between the low-voltage winding 13 and the high-voltage winding 15, and the winding is divided into several sections with equal number of turns in each section, which can ensure To ensure voltage stability and load balance, the insulating barrier 14 plays an insulating role, which can effectively prevent electrical breakdown and leakage. At the same time, the heat exchange guide channel 16 arranged in the middle of the insulating barrier 14 can allow the cooling oil to pass through, thereby increasing the heat dissipation of the winding. Effective heat dissipation measures can reduce the temperature of the transformer and ensure the stability of the transformer when it is running under high load, thereby improving the load capacity of the transformer. At the same time, the winding slot 17 plays a guiding role so that the high-voltage winding 15 can be segmented. The segmented winding can be optimized to the winding structure, thereby ensuring voltage stability and load balance. The sound insulation pad 18 plays a certain sound insulation role. When the installation height of the transformer needs to be adjusted, the adjustment cylinder 26 can be twisted to drive the adjustment push block 27. The push block 27 is adjusted to rotate and perform a spiral lifting motion along the external thread 201. The lifting of the push block 27 drives the gasket 28 to perform a synchronous lifting motion. The gasket 28 moves to push the support spring 25 to perform a lifting motion. The support spring 25 moves to drive the connecting tube 19 and the transformer housing 1 to perform a synchronous lifting motion, thereby achieving the required installation height of the transformer, so as to facilitate installation at different positions. The iron core 11 of the transformer is composed of silicon steel sheets. Under the action of the electromagnetic field, the silicon steel sheets will undergo magnetostriction, that is, the size along the direction of the magnetic lines of force will change. After the excitation disappears, the silicon steel sheets will return to their original shape. This periodic expansion and contraction change will cause the vibration of the iron core 11, thereby driving the overall vibration of the transformer to generate noise. When the transformer vibrates, it will bring The movable connecting tube 19 is synchronously slightly vibrated, and the support spring 25 is used to isolate the shaking of the support tube, so as to prevent the transformer vibration from being transmitted to the mounting frame 21 and thus transmitting the noise. At the same time, the damping ring 29 has a damping effect on the rebound of the support spring 25 after the vibration isolation buffer, so as to prevent the transformer and the support spring 25 from continuously shaking. The support spring 25 cooperates with the adjusting push block 27 so that the transformer can be installed at a high height while reducing noise and keeping the surrounding environment quiet. The oil pump 32 can circulate the cooling oil in the transformer housing 1 to the heat exchange pipe 31 and then flow back to the transformer housing 1, so that the cooling oil can circulate and flow, thereby enhancing the heat dissipation effect of the transformer.At the same time, cooling water can be stored in the heat exchange water tank 33, and the heat exchange effect of the cooling oil can be achieved through the heat exchange pipe 31 inside the heat exchange water tank 33, so as to improve the heat dissipation effect of the transformer and the service life of the transformer. The oil pillow 34 can adjust the volume of the transformer oil to adapt to the expansion and contraction caused by the change of oil temperature, so as to ensure that the oil tank is always full of oil. The main function of the high-voltage outlet terminal 35 and the low-voltage outlet terminal 36 is to lead the high-voltage and low-voltage electric energy inside the transformer to the external circuit for the transmission and distribution of electric energy. The above is the working principle of the low-noise transformer with optimized winding structure.
