Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0021] Technical effects and advantages of the present invention:

[0022] 1. When the electronic valve is closed, the cooling oil entering from the first circulation pipeline will push the lifting scraper upward, and the outer periphery of the lifting scraper will scrape the inner wall of the heat dissipation chamber, achieving the purpose of self-cleaning the inner wall of the heat dissipation chamber;

[0023] 2. When the circulation pump starts, even if it cannot drive the cooling oil to circulate successively between the first circulation pipeline, the radiator, the second circulation pipeline and the transformer housing, it can also drive the blades to rotate, increasing the air fluidity around the radiator and making the heat exchange effect of the radiator better;

[0024] 3. The cooling oil plays an insulating and cooling role at the connection of the porcelain bushing connector, avoiding the problem of high-temperature leakage. Moreover, the cooling oil in the insulating sleeve can communicate with the cooling oil inside the transformer housing, achieving the purpose of promoting cooling and heat dissipation;

[0025] 4. Before replacing the new cooling oil, this solenoid valve can be opened to inject a part of the detergent dispersant stored in the cleaning box into the inside of the insulating sleeve, which can clean the stains such as oil films inside the insulating sleeve and the transformer housing. When the cooling oil is drained, the inside of the transformer housing is relatively clean;

[0026] 5. When high pressure appears inside the transformer housing, the pressure will push the second explosion-proof piece to move and compress the spring. At this time, the high air pressure inside the transformer housing will be discharged through the pressure relief port, the explosion-proof groove and the gap between the first explosion-proof piece and the second explosion-proof piece, achieving the purpose of pressure relief and explosion protection; when the pressure returns to normal, the second explosion-proof piece uses the elastic force of the spring to reset and seal at the explosion-proof groove, avoiding the phenomenon of a large amount of cooling oil being discharged inside the transformer housing. Therefore, when high pressure appears inside the transformer housing, it can largely maintain normal use, enabling the transformer housing to operate until the maintenance personnel come to handle it, without the need to stop the machine for repair.

Detailed implementation manners

[0037] The present invention provides a highly efficient heat dissipation type transformer as Figures 1-9 shown, including a transformer housing 1 and an iron core 29 disposed inside the transformer housing 1. Radiators 2 are provided on both sides of the transformer housing 1, and a plurality of radiators 2 are provided. A second circulation pipeline 4 is provided above the transformer housing 1, and a first circulation pipeline 3 is provided below the transformer housing 1. A plurality of metal heat sinks 6 are provided on the radiator 2. The metal heat sinks 6 are in a rectangular sheet structure and penetrate through the inside and outside of the radiator 2 at the same time. The plurality of metal heat sinks 6 divide the inside of the radiator 2 into a plurality of heat dissipation chambers 18. The second circulation pipeline 4 is connected between the upper end of the heat dissipation chamber 18 and the inside of the upper end of the transformer housing 1, and the first circulation pipeline 3 is connected between the lower end of the heat dissipation chamber 18 and the inside of the lower end of the transformer housing 1. A circulation pump 5 is provided at the bottom of the radiator 2. Cooling oil is stored in the transformer housing 1. When the circulation pump 5 is started, the cooling oil is transported from the first circulation pipeline 3 into the heat dissipation chamber 18 for heat exchange, and the heat-exchanged cooling oil enters the inside of the transformer housing 1 from the second circulation pipeline 4 to dissipate heat from the iron core 29.

[0038] Refer to Figure 5 andFigure 6 As shown, in the present invention, a lifting scraper 20 is provided at the bottom of the heat dissipation chamber 18. An intermediate hole 21 is provided in the middle of the lifting scraper 20. The intermediate hole 21 penetrates through the upper and lower surfaces of the lifting scraper 20 at the same time. An electronic valve 22 is provided in the intermediate hole 21. The outer periphery of the lifting scraper 20 is movably attached to the inner wall of the heat dissipation chamber 18. When the electronic valve 22 is in the open state, the cooling oil entering from the first circulation pipeline 3 can normally enter the interior of the heat dissipation chamber 18 through the intermediate hole 21, and then enter the second circulation pipeline 4 and the interior of the transformer housing 1 in sequence, realizing the internal and external circulation of the cooling oil. When the electronic valve 22 is in the closed state, the cooling oil entering from the first circulation pipeline 3 will push the lifting scraper 20 to rise, and the outer periphery of the lifting scraper 20 scrapes the inner wall of the heat dissipation chamber 18, achieving the purpose of self-cleaning the inner wall of the heat dissipation chamber 18.

[0039] A blade 17 is also connected to the rotating shaft of the circulation pump 5. The blade 17 is located at the bottom of the radiator 2. When the circulation pump 5 is started, it cannot drive the cooling oil to circulate between the first circulation pipeline 3, the radiator 2, the second circulation pipeline 4 and the transformer housing 1 in sequence, but can also drive the blade 17 to rotate, increasing the fluidity of the air around the radiator 2, making the heat exchange effect of the radiator 2 better.

[0040] Reference Figure 1 As shown, a porcelain insulator connector 7 is provided above the transformer housing 1. The porcelain insulator connector 7 is mainly used to connect external wires, electrical equipment, etc. The connection part needs to be sealed, and problems such as high-temperature leakage are also likely to occur. Therefore, in the present invention, an insulating sleeve 8 is sleeved on the outer ring at the bottom of the porcelain insulator connector 7. The insulating sleeve 8 is communicated with the interior of the transformer housing 1. The insulating sleeve 8 is also filled with cooling oil. The cooling oil plays an insulating and cooling role in the connection part of the porcelain insulator connector 7, avoiding the problem of high-temperature leakage, and the cooling oil in the insulating sleeve 8 can circulate with the cooling oil inside the transformer housing 1, achieving the purpose of promoting cooling and heat dissipation.

[0041] Considering that the cooling oil needs to be replaced regularly, but in the prior art, the method of replacing the cooling oil is to directly discharge the cooling oil from the discharge port 10 at the lower end of the transformer housing 1 and inject new cooling oil into the inlet 9 at the upper end of the transformer housing 1. However, the oil film and other stains formed inside the transformer housing 1 cannot be removed. Therefore, in the present invention, a cleaning tank 12 is provided on one side above the transformer housing 1. The cleaning tank 12 is used to store a detergent-dispersant. The position of the cleaning tank 12 is higher than that of the transformer housing 1. A main pipeline 13 is provided at the bottom of the cleaning tank 12. One end of the main pipeline 13 away from the cleaning tank 12 is communicated with the inside of the transformer housing 1, and an auxiliary pipeline 14 is provided at the end of the main pipeline 13 away from the cleaning tank 12. The auxiliary pipeline 14 has a plurality of branch pipelines, and the branch pipelines are respectively communicated with the corresponding insulating bushings 8. A solenoid valve is provided at the connection between the main pipeline 13 and the cleaning tank 12. Before replacing the new cooling oil, this solenoid valve can be opened to inject a part of the detergent-dispersant stored in the cleaning tank 12 into the inside of the insulating bushing 8, so as to clean the oil film and other stains inside the insulating bushing 8 and the transformer housing 1. When the cooling oil is discharged again, the inside of the transformer housing 1 is relatively clean.

[0042] Moreover, the cleaning tank 12 stores a large amount of detergent-dispersant, which can be used multiple times, reducing the frequency of manual maintenance.

[0043] An injection pipe 15 and a discharge pipe 16 are provided on the cleaning tank 12. Stainless steel connectors 26 are fixedly provided at the bottoms of the injection pipe 15 and the discharge pipe 16. The injection pipe 15 is docked with an auxiliary pipeline. The auxiliary pipeline includes an auxiliary pipeline 23 and an auxiliary docking sleeve 24. The auxiliary docking sleeve 24 is integrally provided at the upper end of the auxiliary pipeline 23. The auxiliary docking sleeve 24 has a conical cylinder structure. The upper end opening of the auxiliary docking sleeve 24 is large. A magnetic suction cup 25 is fixedly provided inside the auxiliary docking sleeve 24. A reserved hole 27 is provided in the middle of the magnetic suction cup 25. A rubber sealing ring 28 is fixedly provided on the inner wall of the auxiliary docking sleeve 24. During operation, a pump body can be connected to the end of the auxiliary pipeline 23, and the pump body can be used to sequentially transport the detergent-dispersant through the auxiliary pipeline 23, the reserved hole 27, the stainless steel connector 26 and the injection pipe 15 into the cleaning tank 12, which is more convenient for adding the detergent-dispersant. Similarly, when discharging the excess or expired detergent-dispersant in the cleaning tank 12, the auxiliary docking sleeve 24 can also be used to dock with the discharge pipe 16 for operation. Connecting the injection pipe 15, the discharge pipe 16 and the auxiliary docking sleeve 24 can be directly operated on the ground. The stainless steel connector 26 will be adsorbed and fixed on the auxiliary docking sleeve 24 by magnetic adsorption, which is simple and convenient.

[0044] Considering the explosion-proof property of the transformer housing 1, an explosion-proof component 11 is further provided on the transformer housing 1, and multiple groups of explosion-proof components 11 are provided; the explosion-proof component 11 includes a first explosion-proof sheet 32 and a second explosion-proof sheet 33. A pressure relief port 31 is provided on the transformer housing 1. The first explosion-proof sheet 32 is attached to the pressure relief port 31, and the second explosion-proof sheet 33 is attached to the side of the first explosion-proof sheet 32 away from the pressure relief port 31. The second explosion-proof sheet 33 and the first explosion-proof sheet 32 are jointly fixed to the transformer housing 1 by a connecting screw 35; an explosion-proof groove 34 is provided on the first explosion-proof sheet 32; the first explosion-proof sheet 32, the transformer housing 1 and the connecting screw 35 are connected by thread fit; a threaded section and a smooth section are provided on the outer circumference of the connecting screw 35; the connecting screw 35 passes through the second explosion-proof sheet 33 movably; a spring 36 is provided between the nut of the connecting screw 35 and the surface of the second explosion-proof sheet 33.

[0045] During operation, when high pressure appears inside the transformer housing 1, the pressure will push the second explosion-proof sheet 33 to move and compress the spring 36. At this time, the high air pressure inside the transformer housing 1 will be discharged through the pressure relief port 31, the explosion-proof groove 34 and the gap between the first explosion-proof sheet 32 and the second explosion-proof sheet 33, achieving the purpose of pressure relief and explosion protection; when the pressure returns to normal, the second explosion-proof sheet 33 uses the elastic force of the spring 36 to reset and seal at the explosion-proof groove 34, avoiding the phenomenon of a large amount of cooling oil in the transformer housing 1 being discharged. Therefore, when high pressure appears inside the transformer housing 1, it can largely maintain normal use, enabling the transformer housing 1 to operate until the maintenance personnel come to deal with it, without the need to stop the machine for repair.

[0046] A filter layer 30 is installed on the inner wall of the transformer housing 1, and the filter layer 30 is located at the connection between the first circulation pipeline 3 and the transformer housing 1; the filter layer 30 is used to filter impurities such as oil stains. For example, after using the lifting scraper 20 to scrape off the oil stains and other impurities on the inner wall of the heat dissipation chamber 18, the oil stains and other impurities will be pushed through the second circulation pipeline 4 and enter the inside of the transformer housing 1. When the cooling oil passes through the first circulation pipeline 3 and enters the heat dissipation chamber 18 again, the oil stains and other impurities will be filtered out by the filter layer 30 inside the transformer housing 1 and will be removed later as the cooling oil is discharged from the discharge port 10; it is relatively convenient to use and achieves the purpose of internal circulation filtration and self-cleaning.

[0047] It should be noted that, in actual use, a specific method can also be used for treatment to ensure that impurities such as oil stains do not remain inside the heat dissipation chamber 18. For example, after using the lifting scraper 20 to move upward to scrape the inner wall of the heat dissipation chamber 18, the solenoid valve 22 is opened at this time, and cooling oil is continuously injected into the interior of the heat dissipation chamber 18. The lifting scraper 20 will slowly rather than drop to the bottom of the heat dissipation chamber 18 all at once. At this time, the oil stains and other impurities remaining on the upper surface of the lifting scraper 20 will be pushed and smoothly discharged from the second circulation pipeline 4 to the transformer housing 1, avoiding the phenomenon that when the oil stains and other impurities stay at the bottom of the heat dissipation chamber 18 with the lifting scraper 20 and are discharged, work needs to be done against gravity.

[0048] In the present invention, access holes 19 are provided at the positions where the second circulation pipeline 4 and the first circulation pipeline 3 are connected to multiple heat dissipation chambers 18, ensuring that the cooling oil enters the multiple heat dissipation chambers 18 evenly and improving the heat dissipation effect.
