For example, a three-phase five-column amorphous alloy transformer with application number CN201710091755.0 is currently disclosed.

[0025] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0026] 1. A split-frame assembly mechanism is set up. By combining the bottom plate, top cover, vertical rod, screw, worm gear, rotating drum, traction rod, splicing plate and clamping frame, the U-shaped core can be conveniently divided into two groups of frames, realizing modular splicing. At the same time, the U-shaped core can be installed separately, and U-shaped cores of different thicknesses can be clamped and adjusted as needed, thereby improving adaptability. Then, by combining the positioning cylinder and the positioning screw, the two U-shaped core frames can be conveniently spliced ​​together. During splicing, the coil is positioned and installed between the U-shaped cores, simplifying the installation steps of the U-shaped core and the coil. At the same time, it is convenient to disassemble the U-shaped core and the coil, thereby improving the convenience of maintenance and replacement.

[0027] The U-shaped core is fixed to the chassis by the screw thread, and the U-shaped core is fixed to the chassis by the screw thread, so that the U-shaped core can be fixed to the chassis by the screw thread, and the U-shaped core can be fixed to the chassis by the screw thread, so that the U-shaped core can be fixed to the chassis by the screw thread, and the U-shaped core can be fixed to the chassis by the screw thread, so that the U-shaped core can be fixed to the chassis by the screw thread, so that the U-shaped core can be fixed to the chassis by the screw thread, so that the U-shaped core can be fixed to the chassis by the screw thread,

[0028] 2. A heat dissipation and energy-saving adjustment mechanism is set up. Through the cooperation of the heat exchange tube, heat sink and heat sink, the heat inside the transformer is transferred to the heat exchange tube, heating the water-based coolant, causing it to expand due to the heat and enter the heat sink. Then, the heat is dissipated through the heat sink to reduce the temperature inside the transformer.

[0029] Through the coordination of the gantry, piston plate, slide rod, top plate, collar, pad and touch switch, when the water-based coolant is continuously heated and its volume continues to expand, the piston plate and slide rod are pushed up to contact the touch switch, starting the fan, allowing air to enter the heat dissipation fins through the air inlet channel, thereby improving the efficiency of heat exchange and enhancing the heat dissipation effect;

[0030] As the water-based coolant continues to expand, it pushes the pad up and contacts the touch switch on the gantry, starting the water pump. Through the cooperation of the suction pipe, cross pipe, spray pipe, water box and return pipe, it performs cyclic spraying to wet the heat sink fins. In conjunction with the fan, it improves the efficiency of water evaporation, quickly takes away heat, further improves the intensity of heat dissipation, and quickly reduces the temperature inside the transformer, thereby reducing the heat absorbed by the water-based coolant, facilitating the resetting of the piston plate and pad, releasing the contact with the touch switch, turning off the fan and water pump, and adjusting the heat dissipation intensity in real time as needed, reducing energy consumption while ensuring the heat dissipation effect.

[0031] In summary, modularization is achieved through the frame combination mechanism, which makes it convenient to divide the U-shaped iron core into two groups. They are first clamped and installed separately and then spliced, which improves the convenience of disassembly and assembly, facilitates subsequent maintenance and replacement, and increases the service life. In addition, the heat dissipation and energy-saving adjustment mechanism is used to adaptively adjust the heat dissipation method and intensity according to the heat inside the transformer, saving energy and reducing costs.

The other end of the return pipe 425 is connected to one end of the water tank 417, and the installation position of the spray pipe 421 corresponds to the installation position of the heat dissipation fins 422.

[0059] The working principle and use process of the present invention are as follows: first, two groups of U-shaped iron cores 312 are placed inside the combined bottom plate 302 and the combined top cover 305 respectively, and then the vertical rod 314 is rotated to drive the worm 315 to rotate, and through the cooperation and transmission of the worm gear 316, the rotating drum 308 is pushed to rotate, and the traction rod 309 is pulled to move, and through the cooperation of the splicing plate 310, the clamping frame 311 slides on the fixed plate 306, and the U-shaped iron cores 312 of different thicknesses are clamped and fixed as needed, thereby improving the stability of the U-shaped iron core 312 on the combined bottom plate 302 and the combined top cover 305, and the U-shaped frame 320 on the clamping frame 311 is used to further limit the U-shaped iron core 312 to prevent it from tipping over;

[0060] Then, the clamping frame 311 moves, driving the limiting slide plate 322 to slide along the limiting groove 321, and driving the bracket 323, screw 324, lifting plate 325 and pinch plate 326 to slide, forcing the pinch plate 326 to be inserted into the U-shaped core 312. At the same time, the rotating shaft sleeve 329 rotates to drive the lifting plate 325 and pinch plate 326 to slide, so that the pinch plate 326 moves and fits tightly against the inner wall of the U-shaped core 312, thereby limiting the position of the U-shaped core 312, further improving the stability of the U-shaped core 312 inside the clamping frame 311 and reducing shaking.

[0061] Next, the coil 313 is put on the U-shaped iron core 312, and the combined top cover 305 is reversed to align with the combined bottom plate 302, and the positioning screw 304 is embedded in the positioning cylinder 303. At the same time, the positioning screw 304 is rotated to move along the positioning cylinder 303, thereby bringing the combined top cover 305 and the U-shaped iron core 312 down, forcing the two U-shaped iron cores 312 to be aligned and spliced ​​together to form a complete transformer core. At the same time, the insertion rod 317 is embedded in the insertion hole 318, and the anti-deflection plate 319 is embedded in the groove to limit the splicing frame 307 and the clamping frame 311, thereby ensuring the alignment effect, preventing deviation, and improving the alignment effect of the two U-shaped iron cores 312;

[0062] Subsequently, the rotating sleeve 329 is rotated to move the traction plate 327 and the support plate 328 to clamp and limit the coil 313, and the buckle plate 326 is used to improve the limiting effect to prevent the coil 313 from shaking and ensure stability. When disassembling, the positioning screw 304 is rotated in the opposite direction to separate the combined top cover 305 and the combined bottom plate 302, thereby facilitating the subsequent removal of the coil 313 and the U-shaped iron core 312, improving the convenience of replacement and facilitating maintenance and upgrading.

[0063] Then, when the transformer is working, the heat generated inside is transferred to the inside of the heat exchange tube 402 through the action of the heat sink 404, causing the water-based coolant therein to expand due to the heat, rise along the heat exchange tube 402 to the inside of the heat dissipation tube 403, and then dissipate heat through the heat sink 404 on the outside of the heat dissipation tube 403. After the temperature is reduced, it shrinks and falls into the inside of the heat exchange tube 402 again. When the temperature inside the transformer is high, the water-based coolant inside the heat dissipation tube 403 cannot quickly discharge the heat. As it continues to rise, it pushes the piston plate 408, the slide rod 407 and the top plate 414 upward, contacts the touch switch 413 on the pad 412, starts the fan 415, generates wind, and sends the external wind into the heat dissipation fins 422 through the air inlet channel 426, thereby improving the heat dissipation efficiency, reducing the temperature inside the transformer, reducing the heat absorbed by the water-based coolant, and causing it to shrink and fall back into the inside of the heat exchange tube 402.

[0064] When the temperature of the water-based coolant still cannot drop and the temperature continues to rise and the volume continues to expand, the slide rod 407, the piston plate 408, the top plate 414 and the pad 412 are continuously pushed upward, contacting the touch switch 413 on the gantry 405, and starting the water pump 419, which sends the water in the water tank 417 into the cross pipe 420 through the pumping pipe 418 and sprays it out through the spray pipe 421, so that the water wets the heat dissipation fins 422 and cooperates with the fan 415 to make the water evaporate quickly and take away a large amount of heat, further improving the heat dissipation effect and effectively reducing the temperature inside the transformer. The water that has not evaporated falls into the water receiving box 424 and is sent into the water tank 417 through the return pipe 425 for convenient circulation.

[0065] Finally, when the temperature inside the transformer drops, the tensioning spring 411 cooperates to push the slide bar 407 and the piston plate 408 to reset, release the contact with the touch switch 413, turn off the fan 415 and the water pump 419, reduce energy consumption, and improve convenience.
