[0019] Preferably, the preparation method of the transformer includes the following steps:

[0020] Step S1: The function of the first plate is to provide support for the first spring, and the function of the limiting block is to provide moving support for the first cylinder. When the first motor rotates, it drives the collection wheel to rotate. When the collection wheel rotates, it drives the pull rope to move. When the pull rope moves, it drives the metal shielding sheet to move. When the metal shielding sheet moves, it drives the first cylinder to move. When the first cylinder moves, the metal shielding sheet drives the first spring to move. When the first spring moves, the metal shielding sheet moves.

At this time, when the moving head resets, the chuck is snapped into the card slot by the elastic force of the second spring to fix the pin, realizing the function of quickly replacing the damaged pins of the EE-type reverse plug-in transformer without having to discard all of them and improving the utilization rate.

[0022] Step S3: There is cooling water in the water collection tank. When the cooling block starts, it cools the cooling water. When the water pump starts, it sucks the cooling water into the "丰"-shaped tube. At this time, when the fan starts, it generates wind and blows it towards the surface of the "丰"-shaped tube. The wind cools down through the "丰"-shaped tube and blows towards the winding component through the filter screen to cool it down. The cooling water enters the nozzle through the water pipe. The cooling water is sprayed towards the conical row through the nozzle. The cooling water is dispersed by the conical row.

[0023] Step S4: When the processing module detects a suitable temperature state, the processing module controls the cooling component to maintain the current power. While the cooling component maintains the current power, the temperature sensor continuously detects the temperature of the winding component until the processing module detects a high temperature state or a low temperature state. When the processing module detects a high temperature state, the processing module controls the cooling component to increase the current power. While the cooling component increases the current power, the temperature sensor continuously detects the temperature of the winding component until the processing module detects a suitable temperature state or a low temperature state. When the processing module detects a low temperature state, the processing module controls the cooling component to reduce the current power. While the cooling component reduces the current power, the temperature sensor continuously detects the temperature of the winding component until the processing module detects a suitable temperature state or a high temperature state, realizing the function of keeping the EE-type reverse plug-in transformer at a suitable working temperature at all times and improving the working efficiency.

[0026] 2. The present invention is equipped with a moving head that drives the contact plate to move, the contact plate drives the No. 2 rod to move, the No. 2 rod moves the contact plate drives the No. 2 spring to move, the No. 2 spring moves the contact plate drives the clamping head to move, the clamping head moves to move out of the slot, at which time the pin is pulled out, and after the pin is replaced, it contacts the contact piece, and the moving head resets, the elastic force of the No. 2 spring clamps the clamping head into the slot to fix the pin, thereby realizing the function of quickly replacing the bad pins of the EE type reverse plug-in transformer without having to discard all of them, improving the utilization rate;

[0027] 3. The present invention is equipped with a water collection tank containing cooling water. The cooling block is started to cool the cooling water. The water pump is started to suck the cooling water into the "Feng"-shaped tube. At this time, the fan is started to generate wind force to blow toward the surface of the "Feng"-shaped tube. The wind cools the air through the "Feng"-shaped tube and then blows toward the winding component through the filter to cool it down. The cooling water enters the nozzle through the water pipe and is sprayed toward the conical row through the nozzle. The cooling water is dispersed by the conical row and falls onto the surface of the cooling block to quickly cool it and improve the cooling effect. This realizes the function of quickly cooling and improving the cooling effect of the EE type reverse plug-in transformer.

[0028] 4. The present invention is equipped with a processing module that controls the cooling component to maintain the current power when it detects a suitable temperature state. The temperature sensor detects the temperature of the winding component in real time while the cooling component maintains the current power until the processing module detects a high temperature state or a low temperature state.

When the processing module detects a low temperature state, the processing module controls the cooling component to reduce the current power. When the cooling component reduces the current power, the temperature sensor detects the temperature of the winding component in real time until the processing module detects a suitable temperature state or a high temperature state. This realizes the function of the EE type reverse plug-in transformer always maintaining a suitable operating temperature to improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the processing module detects a high temperature state, the processing module controls the cooling component to increase the current power. While the cooling component increases the current power, the temperature sensor 25 detects the temperature of the winding component 2 in real time until the processing module detects a suitable temperature state or a low temperature state. When the processing module detects a low temperature state, the processing module controls the cooling component to reduce the current power. While the cooling component reduces the current power, the temperature sensor 25 detects the temperature of the winding component 2 in real time until the processing module detects a suitable temperature state or a high temperature state, thereby realizing the function of the EE type reverse plug-in transformer to always maintain a suitable operating temperature and improve work efficiency.

[0047] Step S1, the function of the No. 1 plate 13 is to provide support for the No. 1 spring 14, the function of the limit block 7 is to provide mobile support for the No. 1 drum 6, the No. 1 motor 10 rotates to drive the collection wheel 11 to rotate, the collection wheel 11 rotates to drive the pull rope 12 to move, the pull rope 12 moves to drive the metal shielding piece 9 to move, the metal shielding piece 9 moves to drive the No. 1 drum 6 to move to drive the metal shielding piece 9 to move the No. 1 spring 14 to move, the No. 1 spring 14 moves to move the metal shielding piece 9, the metal shielding piece 9 moves to reduce the EE type reverse plug-in transformer from external strong magnetic field interference, thereby realizing the function of reducing the protection against external strong magnetic field interference and improving the range of magnetic field adaptation of the EE type reverse plug-in transformer;

[0048] Step S2: The moving head 33 moves to drive the contact plate 34 to move. The movement of the contact plate 34 drives the second rod 30 to move. The movement of the second rod 30 causes the contact plate 34 to drive the second spring 32 to move. The movement of the second spring 32 makes the contact plate 34 drive the chuck 35 to move. The movement of the chuck 35 causes it to move out of the card slot 36. At this time, the pin 27 is pulled out. After the pin 27 is replaced, it contacts the contact piece 28. At this time, the moving head 33 resets and the chuck 35 is snapped into the card slot 36 by the elastic force of the second spring 32 to fix the pin 27, realizing the function of quickly replacing the damaged pin 27 of the EE-type reverse plug-in transformer without having to discard all of them, thus improving the utilization rate;

[0049] Step S3: There is cooling water in the water collection tank 18. The cooling block 19 starts to cool the cooling water. The water pump 24 starts to suck the cooling water into the "Feng"-shaped pipe 23. At this time, the fan 17 starts to generate wind and blows it towards the surface of the "Feng"-shaped pipe 23. The wind is cooled by the "Feng"-shaped pipe 23 and then blows towards the winding assembly 2 through the filter screen 16 to cool it. The cooling water enters the nozzle 22 through the water pipe 21. The cooling water is sprayed from the nozzle 22 onto the conical row 20. The cooling water is dispersed by the conical row 20. The dispersed cooling water falls onto the surface of the cooling block 19 to quickly cool it, improving the cooling effect, realizing the function of quickly cooling the EE-type reverse plug-in transformer and improving the cooling effect;

[0050] Step S4: When the processing module detects a suitable temperature state, the processing module controls the cooling component to maintain the current power. While the cooling component maintains the current power, the temperature sensor 25 continuously detects the temperature of the winding assembly 2 until the processing module detects a high temperature state or a low temperature state. When the processing module detects a high temperature state, the processing module controls the cooling component to increase the current power. While the cooling component increases the current power, the temperature sensor 25 continuously detects the temperature of the winding assembly 2 until the processing module detects a suitable temperature state or a low temperature state. When the processing module detects a low temperature state, the processing module controls the cooling component to reduce the current power. While the cooling component reduces the current power, the temperature sensor 25 continuously detects the temperature of the winding assembly 2 until the processing module detects a suitable temperature state or a high temperature state, realizing the function of keeping the EE-type reverse plug-in transformer at a suitable working temperature at all times and improving the working efficiency.

[0051] Working principle: The function of the first board 13 is to provide support for the first spring 14. The function of the limit block 7 is to provide moving support for the first cylinder 6.

The movement of the metal shielding sheet 9 reduces the anti-external strong magnetic field interference of the EE type reverse plug-in transformer, realizing the function of reducing the anti-external strong magnetic field interference of the EE type reverse plug-in transformer and improving the magnetic field adaptation range. The movement of the moving head 33 drives the movement of the contact plate 34. The movement of the contact plate 34 drives the movement of the second rod 30. The movement of the second rod 30 causes the contact plate 34 to drive the movement of the second spring 32. The movement of the second spring 32 causes the contact plate 34 to drive the movement of the chuck 35. The movement of the chuck 35 causes it to move out of the card slot 36. At this time, pull the pin 27 to pull it out. After the pin 27 is replaced, it contacts the contact piece 28. At this time, the moving head 33 resets and the chuck 35 is snapped into the card slot 36 by the elastic force of the second spring 32 to fix the pin 27, realizing the function of quickly replacing the damaged pin 27 of the EE type reverse plug-in transformer without having to discard it all, thus improving the utilization rate.
