With the development of smart grids, modern pole-mounted transformers are integrating more automation functions and becoming important nodes of smart distribution networks. Therefore, a transformer capable of adjusting temperature in different zones is disclosed in Chinese Patent No. CN202511154930.7, which starts the second motor to drive the adjusting frame to rotate, adjusts the inlet size of each zone of the circulating pipeline, and then adjusts the cooling water flow rate of each zone of the circulating pipeline, achieving the effects of adjusting temperature in different zones, improving equipment operation efficiency and prolonging service life.

[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 three-dimensional multi-angle monitoring mechanism is set up. Through the cooperation of various components within the three-dimensional multi-angle monitoring mechanism, the detection process during transformer use is optimized. External vibration sensors, pressure sensors, internal vibration sensors, and top temperature sensors arranged in different positions monitor the operating status of the transformer. Furthermore, the working status is monitored in real time by measuring the internal temperature of the transformer, the hydraulic oil level, and the vibration of the internal and external environment. When abnormal data is detected in the transformer, a response can be made and maintenance can be carried out. This effectively avoids the failure to detect small faults in time during transformer operation, which may lead to major faults. It improves the convenience of transformer maintenance and reduces the maintenance cost of the transformer. Simultaneously, utilizing the principle of thermal expansion and contraction of the heat-conducting oil inside the internal temperature-conducting box, the temperature change of the insulating oil inside the transformer synchronously drives the telescopic elastic flat rod to extend and retract, indirectly adjusting the installation cantilever length of the internal vibration sensor. This allows the vibration amplitude of the internal vibration sensor to change with the temperature change of the insulating oil. By comparing the data from the internal vibration sensor with the data from the top temperature sensor, the accuracy of various data detection inside the transformer is further improved. Furthermore, through the cooperation of the glass observation tube, the side supplementary light plate, and the sampling camera, the state of the insulating oil is image sampled, allowing remote maintenance personnel to more intuitively and clearly judge the physical and chemical state of the insulating oil inside the transformer. This expands the types of data sampled during transformer inspection and further improves the monitoring effect of the transformer. Furthermore, during the internal circulation testing of the insulating oil in the transformer body, the insulating oil is filtered to reduce its aging rate, indirectly improving the overall service life of the transformer and extending its maintenance cycle. At the same time, the lifting of the support column increases the tightness of the installation between the transformer body and the mounting frame, effectively reducing the noise generated by natural vibrations during transformer operation, reducing noise pollution during transformer use, and improving the overall environmental friendliness of the transformer.

[0015] 2. An external auxiliary protection adjustment mechanism is set up. Through the cooperation between the various components inside the external auxiliary protection adjustment mechanism, the auxiliary cooling process during the operation of the transformer is optimized. The redundant kinetic energy during the circulation of insulating oil is fully utilized. The circulation of insulating oil drives the airflow inside the air guide box, and the airflow through the diffuser box provides auxiliary heat dissipation for the insulating oil flowing through the heat dissipation return box. This effectively improves the heat dissipation efficiency of the insulating oil circulation process inside the transformer and improves the kinetic energy utilization rate during the operation of the transformer complete set of equipment. Meanwhile, by using an auxiliary blowing fan in conjunction with the blowing top box, a continuous downward airflow can be formed on the outside of the transformer body. This continuous airflow provides continuous heat dissipation to the outside of the transformer body, ensuring that the transformer has good heat dissipation performance during normal operation and further improving the stability and service life of the transformer.

[0016] In summary, by coordinating the various components within the three-dimensional multi-angle monitoring mechanism and the external auxiliary protection and adjustment mechanism, the transformer's detection and cooling process is optimized. Through the cooperation of multiple sensors, the transformer's temperature data, internal and external vibration data, and insulating oil image data are collected. By comparing and verifying different data, the accuracy of overall transformer monitoring is effectively improved, thereby reducing the convenience of transformer monitoring. Simultaneously, during the detection process, the internal insulating oil is filtered and cooled, effectively reducing the transformer's aging rate and extending its overall service life.

[0021] The working principle and usage process of this invention: In the actual application of this invention, when a transformer is needed, the mounting frame 1 is installed on a suitable utility pole by fixing the hoop 2, and the transformer body 3 is installed on the top of the mounting frame 1 in sequence. Then, the bottom control box 4 is installed on the bottom of the mounting frame 1, and the corresponding cables are connected between the transformer body 3 and the bottom control box 4. When it is necessary to test the operating status of the transformer, the insulating oil inside the transformer body 3 is collected through the lower oil tank 501. Then, the insulating oil inside the lower oil tank 501 is introduced into the front liquid pipe 505 through the external circulation pump 504. The insulating oil is then introduced into the glass observation tube 506 through the front liquid pipe 505. As the insulating oil flows through the glass observation tube 506, it drives the transverse rotating blade 512 to rotate. The rotation of the transverse rotating blade 512 drives the inclined scraper 513 to rotate synchronously. During the rotation of the inclined scraper 513, the inner wall of the glass observation tube 506 is continuously scraped to prevent dirt inside the insulating oil from adhering to the inner wall of the glass observation tube 506 and reducing its overall light transmittance. This ensures that the glass observation tube 506 can maintain good light transmittance during the test. When it is necessary to sample the appearance of the insulating oil inside the glass observation tube 506, the side supplement light plate 514 on the side of the arc-shaped suspension 511 is used to supplement the light for the insulating oil inside the glass observation tube 506. Then, the sampling camera 516 on the side of the front mounting bracket 515 is used to sample the state of the insulating oil inside the glass observation tube 506. The image data collected by the sampling camera 516 is transmitted to an external device for image color difference comparison to intuitively judge the aging stage of the insulating oil and ensure that the insulating oil can be detected and replaced in time before it affects the normal use of the transformer body 3. Then, the insulating oil inside the glass observation tube 506 is introduced into the drive box 508 through the transfer pipe 507. As the insulating oil flows through the drive box 508, it drives the internal rotating paddle 509 to rotate continuously. Then, the insulating oil is introduced into the bottom filter treatment box 502 through the transfer back pipe 510. The insulating oil flowing into the bottom filter treatment box 502 is intercepted and filtered by the internal inclined filter screen 519, so that maintenance personnel can filter and intercept the oil inside the bottom filter treatment box 502 through the slag discharge bend bottom pipe 520. Impurities are discharged, which realizes auxiliary filtration and cleaning of insulating oil during the cyclic detection process, thereby indirectly improving the service life of insulating oil. The insulating oil filtered inside the bottom filter treatment box 502 is guided through the heat dissipation return box 503. The insulating oil inside the heat dissipation return box 503 is introduced into the return outer bend pipe 535 through the return conveying pump 534, and the insulating oil inside the return outer bend pipe 535 is guided back into the transformer body 3 through the return rectangular pipe 536. The temperature of the returned insulating oil is detected by the top temperature sensor 537. Meanwhile, when it is necessary to detect the vibration state of the transformer body 3, the vibration state of the mounting frame 1 and the transformer body 3 is detected synchronously by the external vibration sensor 518 fixed on the side of the vertical plate 517, so as to realize the detection of the vibration state of the entire transformer equipment. When it is necessary to detect the internal vibration state of the transformer body 3, the heat of the insulating oil is absorbed by the internal temperature-conducting box 521, causing the heat-conducting oil inside the internal temperature-conducting box 521 to expand after absorbing heat. At the same time, the air bladder inside the supporting rectangular suspension box 531 also expands synchronously after absorbing heat, thereby increasing the volume and pressure of the heat-conducting oil inside the internal temperature-conducting box 521 and the supporting rectangular suspension box 531. The heat-conducting oil inside the internal temperature-conducting box 521 is guided by the liquid-conducting thin suspension tube 522. The heat-conducting oil enters the rectangular inner guide box 527 through the liquid-conducting thin suspension tube 522. The pressure of the heat-conducting oil overcomes the elastic force of the auxiliary horizontal limit spring 530, causing the telescopic elastic flat rod 528 to extend to both sides of the rectangular inner guide box 527. The movement of the telescopic elastic flat rod 528 causes the internal vibration sensor 529 to move away from both sides of the rectangular mounting block 526. The vibration of the transformer body 3 and the lower oil tank 501 is transmitted to the rectangular mounting block 526 and the telescopic elastic flat rod 528 by the detection of the suspended flat box 523. The vibration inside the transformer body 3 is detected by the internal vibration sensor 529. At the same time, as the telescopic elastic flat rod 528 extends, the vibration amplitude of the internal vibration sensor 529 increases, so that the amplitude detected by the internal vibration sensor 529 is significantly increased. Meanwhile, the pressure generated by the insulating oil inside the lower oil tank 501 drives the flexible isolation silicone sheet 524 to deform. The deformation of the flexible isolation silicone sheet 524 squeezes the pressure sensor 525. The pressure sensor 525 detects the magnitude of the force generated by the deformation of the flexible isolation silicone sheet 524. In turn, the pressure sensor 525 indirectly reflects the pressure of the insulating oil inside the lower oil tank 501 and indirectly determines the level of the insulating oil inside the transformer body 3 by the pressure. At the same time, the increase in the internal heat-conducting oil pressure inside the internal heat-conducting box 521 and the supporting rectangular suspension box 531 will also drive the supporting lifting column 533 to rise. Under the action of the elastic force of the spring 532 at the support end, the rubber sleeve at the top of the supporting lifting column 533 will fit more tightly with the bottom of the transformer body 3. The compression of the rubber sleeve at the top of the supporting lifting column 533 will make the connection between the transformer body 3 and the mounting frame 1 more tighter, thereby reducing the noise generated during the high-frequency vibration of the transformer body 3. When auxiliary cooling of the transformer is required during the circulation of insulating oil, the air guide box 602 and its internal components are installed at the bottom of the drive box 508 through the support suspension 601. During the rotation of the internal rotating paddle 509, the air guide drive blade 603 is driven to rotate synchronously. During the rotation of the air guide drive blade 603, the external airflow is drawn into the air guide box 602 through the air inlet rectangular pipe 604. Then, the airflow is guided into the air guide inclined pipe 606 through the exhaust rectangular pipe 605. The airflow is then guided into the blowing diffusion front box 607 through the air guide inclined pipe 606. The blowing diffusion front box 607 blows the continuous airflow towards the side of the heat dissipation return box 503, so as to dissipate heat from the insulating oil flowing through the heat dissipation return box 503 through the continuous airflow. Then, the airflow is guided by the air collection box 608 on the other side of the heat dissipation return box 503, and the airflow inside the air collection box 608 is collected by the auxiliary blowing fan 609. The airflow is introduced into the blowing top box 611 through the liquid guide pipe 610, and the bottom air outlet of the blowing top box 611 is protected by the protective top net 612. Then, the airflow blown out by the blowing top box 611 cools the outside of the transformer body 3.
