High-efficiency distribution transformers refer to distribution transformers that meet the requirements of GB 20052-2024 and achieve Level 1 or Level 2 energy efficiency. By reducing the no-load loss of the iron core (iron loss) and the load loss of the windings (copper loss), the operating energy consumption is significantly lower than that of traditional ordinary transformers. A large amount of heat is generated during the operation of the transformer. Therefore, a corresponding heat dissipation structure is required in the use of high-efficiency transformers. For this purpose, a Chinese patent discloses a high-efficiency energy-saving high-voltage distribution transformer with the application number CN202511067165.5.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A central circulating phase change temperature control mechanism is set up. Through the cooperation between the various components inside the central circulating phase change temperature control mechanism, the temperature control and regulation process during the operation of the distribution transformer is optimized. Through the cooperation between multiple sets of phase change materials inside the temperature control box, the rapid heat absorption and heat release characteristics of the phase change materials during the phase change process are utilized. When the power of the distribution transformer rises or falls rapidly, the phase change of the phase change materials rapidly absorbs the internal heat during the heating stage of the transformer body, and replenishes the internal heat during the rapid cooling stage of the transformer body. This effectively prevents the transformer body from experiencing rapid temperature rises and falls due to changes in the external environment and its own power. Meanwhile, through the chimney effect naturally formed inside the temperature control box and the air guide cone, the continuously rising airflow inside the temperature control box and the air guide cone provides continuous self-heating for the transformer body, which improves the stability of the internal temperature of the transformer body, effectively avoids the aging of the electrical components inside the distribution transformer due to rapid temperature changes, thereby improving the environmental adaptability of the distribution transformer and effectively extending the service life of the distribution transformer. Furthermore, by utilizing the cooperation between the drive rotating box and the various components connected to it, and through the cooperation between the groups inside and outside the temperature control box, the internal components of the drive rotating box are subjected to directional non-uniform heat conduction. This is achieved by utilizing the non-uniform melting of the phase change packing inside the drive rotating box and the displacement of the counterweight steel balls, which drives the drive rotating box and its internal components to rotate intermittently. This converts the heat energy inside the transformer body into the kinetic energy of the drive rotating box for consumption, thus expanding the heat dissipation methods of the distribution transformer and improving the heat dissipation efficiency of the distribution transformer. By utilizing the cooperation between the components on the transmission shaft and the drive side rod, the air guide propeller is driven to rotate continuously at a uniform speed. This helps to generate a continuous upward airflow inside the temperature control box and the air guide cone. By utilizing the thermal expansion and contraction characteristics of the lifting protective cover and its connecting components, the lifting protective cover is automatically raised and lowered by controlling the temperature inside the temperature control box. This effectively improves the dynamic protection performance of the top of the air guide cone, thereby effectively improving the overall heat dissipation effect of the distribution transformer and enhancing its operational stability.

[0015] 2. An external circulation auxiliary heat dissipation mechanism is set up. Through the cooperation between the various components inside the external circulation auxiliary heat dissipation mechanism, the active heat dissipation process of the distribution transformer is optimized. Through the swing inner plate and the dynamic protective structure connecting the various components on it, the tilt angle of the swing inner plate and the reflective heat insulation plate can be adjusted autonomously according to the internal temperature of the transformer body. This ensures that the reflective heat insulation plate can fully shield the top of the transformer body in hot weather, preventing direct sunlight from hitting the top of the transformer body and causing the overall temperature of the distribution transformer to rise. This effectively improves the overall environmental adaptability of the distribution transformer. Meanwhile, through the active circulation of liquid inside the circulating heat exchange plate and the drive box, and the active suction of airflow inside the guide cone by the guide fan, the overall heat exchange efficiency of the distribution transformer is effectively improved. The overall heat dissipation area of ​​the distribution transformer is effectively expanded by the swing inner plate, thereby effectively improving the heat dissipation effect of the distribution transformer and effectively improving the temperature stability of the distribution transformer during operation. Furthermore, by coordinating the various components inside the drive box, the auxiliary warning whistle continuously emits warning sounds. By observing the changes in the warning sounds, the heat dissipation of the distribution transformer can be indirectly determined. The whistle can also be used to scare away birds, preventing them from nesting on the top of the transformer and causing malfunctions. This expands the function of the distribution transformer and further improves its adaptability to different environments.

[0016] In summary, by coordinating the central circulating phase change temperature control mechanism and the outer circulating auxiliary heat dissipation mechanism, the heat exchange regulation process of the distribution transformer is optimized. By segmenting the heat of the distribution transformer, the characteristics of the phase change materials at various locations inside the temperature control box are fully utilized, enabling the distribution transformer to maintain a smooth transition even during rapid power changes. This effectively prevents sudden temperature changes from accelerating the aging rate of the internal electrical components of the distribution transformer, thereby improving the service life of the distribution transformer. Meanwhile, through the cooperation of various heat dissipation methods, the distribution transformer can efficiently dissipate heat in multiple ways during the stable operation phase, ensuring that the distribution transformer can also maintain a suitable temperature range during continuous operation, effectively improving the environmental adaptability of the distribution transformer, and further extending the service life of the distribution transformer.

A reflective heat insulation plate 405 is fixedly connected to the top surface of the swing inner plate 404 via a connecting column, and a support limiting plate 406 is movably connected to the other end of the bottom surface of the swing inner plate 404 via a long oval groove. A circulating heat exchange plate 407 is fixedly connected to the side of the transformer body 2. A circulating top pump 408 is fixedly connected to one end of the top of the circulating heat exchange plate 407 through a pipe. A return top pipe 409 is fixedly connected to the other end of the top of the circulating heat exchange plate 407. The inside of the shift adjustment telescopic box 402 is filled with thermally conductive silicone oil. The outer side of the shift adjustment rod 403 is tightly slidably fitted with the inner wall of the rectangular mounting box 401. The inside of the circulating heat exchange plate 407 is filled with thermally conductive oil. A drive box 410 is fixedly connected to the end of the circulating top pump 408 at one side of the inside of the air guide cone 326 via a pipe. A drive blade 411 is rotatably connected inside the drive box 410 via a rotating shaft. A drive pulley 412 is sleeved on one end of the drive blade 411. A driven pulley 413 is sleeved on the inside of the air guide cone 326 at the top of the drive box 410 via a rotating shaft. A transmission toothed belt 414 is wrapped around the outside of the drive pulley 412 and the driven pulley 413. A drive frame 415 is fixedly connected to the end of the transmission toothed belt 414 at the position corresponding to the outer side of the air guide cone 326, and a warning whistle 416 is fixedly connected to the outer side of the drive frame 415. Both ends of the top of the air guide cone 326 are embedded with guide fans 417. A guide crossbar 418 is fixedly connected to the outer side of the air guide cone 326 at the end position of the guide fans 417. The liquid outlet at the end of the drive box 410 is connected to the return top pipe 409. The drive box 410 and the circulating heat exchange plate 407 form a circulation loop through the pipe. The guide fans 417 are driven by an external motor. Through the cooperation between the components inside the external circulation auxiliary heat dissipation mechanism 4, the active heat dissipation process of the distribution transformer is optimized. Through the swing inner plate 404 and the dynamic protective structure of the components connected to it, the tilt angle of the swing inner plate 404 and the reflective heat insulation plate 405 can be adjusted autonomously according to the internal temperature of the transformer body 2. This ensures that the reflective heat insulation plate 405 can fully shield the top of the transformer body 2 in hot weather, preventing direct sunlight from hitting the top of the transformer body 2 and causing the overall temperature of the distribution transformer to rise. This effectively improves the overall environmental adaptability of the distribution transformer. Meanwhile, through the active circulation of liquid inside the circulating heat exchange plate 407 and the drive box 410, and the active suction of airflow inside the air guide cone 326 by the guide fan 417, the overall heat exchange efficiency of the distribution transformer is effectively improved. Furthermore, the overall heat dissipation area of ​​the distribution transformer is effectively expanded by the swing inner plate 404, thereby effectively improving the heat dissipation effect of the distribution transformer and effectively improving the temperature stability of the distribution transformer during operation. Furthermore, by cooperating with each component inside the drive box 410, the auxiliary warning whistle 416 continuously emits warning sounds, so as to indirectly judge the heat dissipation of the distribution transformer by the changes in the warning sound. The whistle of the warning whistle 416 can also be used to scare away birds, so as to prevent birds from nesting on the top of the transformer body 2 and causing malfunctions. This expands the function of the distribution transformer and further improves the adaptability of the distribution transformer to the operating environment.

[0021] The working principle and usage process of this invention: In the actual application of this invention, during the use of a high-efficiency power distribution transformer, the transformer body 2 located at the top of the bottom support frame 1 will continuously generate heat during use. When the power of the transformer body 2 increases rapidly, the heat generated by the internal components of the transformer body 2 will also increase rapidly. At this time, when it is necessary to adjust the temperature inside the transformer body 2, the vertical phase change flat box 302 and the temperature control phase change box 303 are installed on the side of the transformer body 2 through the temperature control box 301. The heat inside the transformer body 2 is transferred to the vertical phase change flat box 302 through the shell of the transformer body 2 and the temperature control box 301. The heat inside the transformer body 2 is quickly absorbed by the phase change material inside the vertical phase change flat box 302 through the process of solid to liquid transformation, so as to prevent the transformer body 2 from experiencing a sudden temperature rise during use. Furthermore, when the power of the distribution transformer decreases, the heat generated inside the transformer body 2 decreases rapidly. At this time, the phase change material inside the vertical phase change flat box 302 and the temperature control phase change box 303 gradually changes from liquid to solid, and uses the heat released during the phase change material conversion process to replenish the heat inside the transformer body 2, so as to prevent the temperature inside the transformer body 2 from dropping instantaneously. Through the process of the phase change material inside the vertical phase change box 302 changing from solid to liquid, the heat generated by the sudden increase in power of the distribution transformer in the early stage is quickly absorbed, which effectively prevents the internal temperature of the distribution transformer from rising rapidly and affecting the normal use of the internal components of the distribution transformer. During the heat generation stage of the distribution transformer during continuous operation, the phase change material inside the vertical phase change box 302 completely changes from solid to liquid, and the heat inside the vertical phase change box 302 is continuously transferred to the temperature-controlled phase change box 303 and the middle temperature control box 306. While the phase change material inside the temperature-controlled phase change box 303 and the middle temperature control box 306 continuously absorbs heat, the heat emitted from the vertical phase change flat box 302, the temperature-controlled phase change box 303, and the middle temperature control box 306 will simultaneously heat the air in the upper layer of the temperature control box 301. After absorbing heat and expanding, the density of the upper air decreases and it gradually rises, which in turn causes the hot airflow in the upper layer of the temperature control box 301 to rise continuously and generate negative pressure in the lower space. At the same time, the negative pressure causes the external cold airflow to enter the temperature control box 301 from bottom to top through the air inlet box 325. Then, through the chimney effect, a continuous rising airflow is generated inside the temperature control box 301 and the air guide cone 326, so as to dissipate the heat accumulated inside the temperature control box 301 to the outside through the continuous rising airflow, so as to achieve continuous self-heating during the operation of the distribution transformer. As the airflow inside the temperature control chamber 301 continues to rise, the flow direction of the rising airflow is guided by the middle layer guide frame 305 and the lower layer guide frame 307. When the rising airflow passes the end of the middle layer guide frame 305, the heat inside the temperature control chamber 301 is transferred to the drive rotating chamber 310 through the heat-conducting arc corner plate 312. At the same time, the heat insulation arc back plate 311 isolates the heat on the back of the drive rotating chamber 310, and the airflow continuously flowing on the side of the air inlet box 325 provides auxiliary cooling to the bottom area of ​​the drive rotating chamber 310. After the drive rotating chamber 310 rotates away from the side area of ​​the heat-conducting arc corner plate 312, the phase change material inside can quickly dissipate heat, cool and solidify, so as to ensure that the drive rotating chamber 310 can maintain uneven heating during use. As the heat-conducting arc corner plate 312 continuously transfers heat, the temperature of the bending assembly drive box 313 located on the side of the heat-conducting arc corner plate 312 continuously rises. The phase change material inside the bending assembly drive box 313 absorbs heat and continuously melts. As the phase change material melts, it slowly releases the support and restraint on the counterweight steel ball 315, allowing the counterweight steel ball 315 to slide from the edge area of ​​the bending assembly drive box 313 towards the center area under the action of gravity. The counterweight steel ball 315 is then released by the inclined surface of the side of the bending assembly drive box 313. The direction of the falling of the bead 315 is guided, and the expansion and contraction of the hollow filling capsule 314 provides a buffer space for the increased volume of the phase change material during the melting process, so that the internal pressure of the bending assembly drive box 313 remains stable within a suitable range. As the position of the counterweight steel bead 315 inside the bending assembly drive box 313 changes, the overall force state of the drive rotation box 310 changes, causing the drive rotation box 310 to deflect under the action of gravity on the other side of the bending assembly drive box 313. After the corresponding bending assembly drive box 313 is moved away from the side area of ​​the heat-conducting arc corner plate 312 by the rotation of the drive box 310, the phase change material inside the bending assembly drive box 313 begins to re-solidify after being heated by no heat source. During the solidification process of the phase change material, the counterweight steel ball 315 will roll towards the end of the bending assembly drive box 313 under the action of gravity. As the phase change material solidifies, the counterweight steel ball 315 will be supported and limited again to ensure that the bending assembly drive box 313 can carry out the next melting cycle. During the deflection of the drive rotating box 310, the mounting end shaft 308 synchronously drives the transmission shaft 309 to rotate intermittently. The rotation of the transmission shaft 309 drives the mounting inner ring 317 to rotate synchronously. During the rotation of the mounting inner ring 317, kinetic energy is stored by the winding of the energy storage spiral spring 318. As the energy storage spiral spring 318 continues to wind, the torque will continuously increase, so as to drive the drive gear ring 319 through the elastic potential energy stored inside the energy storage spiral spring 318. At the same time, since the starting torque of the drive side rod 316 is less than the torque during the rotation of the drive rotating box 310, the spiral spring 318 can continuously store energy before the drive side rod 316 rotates. When the torque exerted by the drive gear ring 319 on the driven gear 320 is greater than the starting torque of the drive side rod 316, the drive gear ring 319 drives the drive side rod 316 and its components to rotate synchronously through the driven gear 320. The rotation of the drive side rod 316 drives the air guide propeller 332 to rotate continuously. The negative pressure generated during the rotation of the air guide propeller 332 assists the airflow outside the air inlet box 325 to enter the temperature control box 301, so as to assist the continuous circulation of the airflow inside the temperature control box 301. Furthermore, during the rotation of the drive side rod 316, the rotating end box 321 and its internal components are simultaneously driven to rotate synchronously. During the rotation of the rotating end box 321 and the limiting damping block 324, the limiting damping block 324 is pulled by the centrifugal force to extend the limiting spring 323 to store energy. After the limiting damping block 324 contacts the inner wall of the protective round box 322, the friction between the limiting damping block 324 and the inner wall of the protective round box 322 increases the rotational damping of the drive side rod 316. The faster the rotational speed of the drive side rod 316, the greater the damping it experiences. This achieves control over the rotational speed of the drive side rod 316 and improves the stability of the internal components of the temperature control box 301. When the top of the air guide cone 326 needs to be protected under normal temperature conditions, the air outlet at the top of the air guide cone 326 is shielded and protected by the lifting protective cover 331. After the temperature inside the temperature control box 301 rises, the oil storage telescopic box 329 inside the guide rectangular box 328 absorbs heat and expands upward. At the same time as the oil storage telescopic box 329 expands, it drives the rectangular telescopic slide bar 330 and the lifting protective cover 331 to rise synchronously, so as to increase the gap between the lifting protective cover 331 and the air outlet at the top of the air guide cone 326, thereby ensuring the stability of the ventilation inside the temperature control box 301 and the air guide cone 326. When active heat dissipation protection is required on the outside of the transformer body 2, the heat overflowing from the inside of the transformer body 2 heats the transposition adjustment telescopic box 402 inside the rectangular mounting box 401. After absorbing heat, the transposition adjustment telescopic box 402 simultaneously drives the transposition adjustment rod 403 to slide vertically upward. During the upward movement of the transposition adjustment rod 403, the swing inner plate 404 swings along the top of the support limit plate 406. During the swing movement of the swing inner plate 404, the reflective heat insulation plate 405 deflects simultaneously. The reflective heat insulation plate 405 blocks external sunlight to reduce the impact of external light and heat sources on the transformer body 2. At the same time, the guide fan 417 actively draws in the hot air inside the guide cone 326, and the guide crossbar 418 guides the airflow discharged by the guide fan 417 to blow towards the side of the swing inner plate 404, so as to expand the heat dissipation area of ​​the hot airflow through the swing inner plate 404. At the same time, the heat transfer oil inside the circulating heat exchange plate 407 is drawn by the circulating top pump 408 and introduced into the corresponding drive box 410 through the pipeline. Then, the heat transfer oil inside the drive box 410 is returned to the circulating heat exchange plate 407 through the return top pipe 409, so as to realize the continuous circulation of heat transfer oil between the circulating heat exchange plate 407 and the drive box 410. During the process of heat transfer oil flowing through the drive box 410, the continuously flowing heat transfer oil drives the drive blade 411 to rotate, and then the drive blade 411 drives the drive pulley 412 to rotate. During the rotation of the drive pulley 412, the drive toothed belt 414 drives the driven pulley 413 to rotate continuously. The rotation of the driven pulley 413 drives the drive frame 415 to rotate, and during the rotation of the drive frame 415, the warning whistle 416 is simultaneously driven to rotate, so that the warning whistle 416 emits a warning sound during continuous rotation. During the process of heat transfer oil flowing through the drive box 410, it continuously exchanges heat with the rising airflow inside the air guide cone 326 to achieve auxiliary heat dissipation of the transformer body 2.
