Description

Technical Field

[0001] This utility model relates to the field of power transformer technology, and more specifically, to a high-efficiency oil-immersed power transformer. Background Technology

[0002] In existing technologies, firstly, the management of the oil tank in oil-immersed transformers is a long-standing technical challenge. Oil-immersed transformers use insulating oil for heat transfer and insulation protection. As one of the key components of the transformer, the management and maintenance of the oil tank are crucial. However, existing oil-immersed transformer designs often fail to effectively consider how to add special oil to the tank in a timely and convenient manner. Due to the variable working environment and frequent load changes of oil-immersed transformers, the insulating oil in the tank may experience a decrease in oil quantity or a deterioration in oil quality after long-term use.

[0003] Secondly, the inconsistent temperature of the auxiliary oil tank also seriously affects the operation of the oil-immersed transformer. The auxiliary oil tank is usually used to receive the overflow oil in the transformer tank or the depressurized oil after a certain period of time. Since the temperature of the insulating oil in the tank is not completely consistent, especially the oil temperature at the bottom of the tank is higher, while the oil temperature at the top is relatively lower.

[0004] In addition, the lack of external protection design is also a major defect of oil-immersed power transformers. Oil-immersed transformers are often placed outdoors or in industrial areas, and their external protection measures are inadequate, making them susceptible to environmental factors. For example, strong winds, rain, dust, birds, animals, etc. may cause direct damage to the transformer or affect its normal operation. Without sufficient external protection measures, transformers are not only susceptible to impacts from external objects, but may also fail due to extreme weather or natural disasters.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a high-efficiency oil-immersed power transformer, which has the following beneficial effects:

[0018] 1. The design of the oil-immersed assembly makes the injection, extraction, and transportation of oil inside the transformer more efficient, convenient, and safe. Through the cooperation of the oil injection cylinder and the pump body, oil can be automatically extracted and sent into the transformer cylinder, ensuring that the transformer always maintains a suitable oil level and avoiding oil shortage or excess. This process does not require manual intervention, reducing the risk of human operation and ensuring continuous circulation and timely replacement of oil, thereby improving the transformer's operational stability and long-term efficient operation.

[0019] 2. The rotating assembly, driven by a motor, rotates the stirring rod and stirring roller, effectively promoting oil mixing and preventing oil stratification or uneven heating. This continuous stirring action ensures uniform temperature distribution of the oil inside the transformer, improving oil cooling efficiency. Especially under high load operation, it can effectively reduce temperature rise and avoid damage caused by overheating. In addition, the design of the rotating rod and rotating blades further enhances the oil stirring effect, allowing the oil to be better distributed in each working area, improving the transformer's heat dissipation capacity and extending its service life.

[0020] 3. The design of the protective components plays an important role in safety. Through the stable configuration of the support base and support rod, the protective plate can be firmly installed, thereby protecting the transformer components while ensuring the safety of the external environment. The setting of the protective net effectively prevents external personnel from accidentally touching the transformer body, especially the oil-immersed components, reducing safety accidents or failures caused by contact. The design of the spikes serves as a warning, further improving safety and preventing personnel from climbing and misoperating. Attached Figure Description

The transformer body 2 is mounted on the base plate 1, the cylinder 3 is mounted on top of the transformer body 2, the oil injection cylinder 4 is mounted on one end of the transformer body 2, the pump body 5 is mounted on the oil injection cylinder 4, and the extraction pipe 6 connects the pump body 5 and the oil injection cylinder 4. A rotating assembly is mounted inside the cylinder 3, which includes a motor 7, a support frame 8, and a stirring rod 9. The motor 7 is mounted on the cylinder 3, the support frame 8 is mounted between the cylinder 3 and the transformer body 2, and the stirring rod 9 is connected to the output end of the motor 7.

[0031] A connecting pipe 10 is provided between the cylinder 3 and the pump body 5, and an oil injection pipe 11 is installed on the oil injection cylinder 4.

[0034] A rotating plate 15 is connected to the rotating rod 14.

[0035] In this embodiment, during use, the threaded cap 12 is removed by rotating along the thread of the oil injection pipe 11, and then the oil is injected into the oil injection cylinder 4 along the oil injection pipe 11. When it is necessary to extract the oil from the oil injection cylinder 4 into the cylinder 3 during use, the pump body 5 is activated to extract the oil from the oil injection cylinder 4 along the extraction pipe 6, and then it flows into the cylinder 3 along the connecting pipe 10, thus completing the use of the device 2 and facilitating the oil delivery process. Furthermore, during use, the motor 7 is activated to drive the stirring rod 9 at the output end to rotate, thereby driving the stirring roller 13 to fully mix the oil. Additionally, the rotating rod 14 is used to adjust the connected rotating plate 15, further ensuring thorough mixing of the oil. This ensures that the insulating oil entering the cylinder 3 at different times is fully mixed, maintaining a consistent temperature within the cylinder 3 and thus increasing the speed of insulating oil depressurization.

[0036] Please see Figure 1-4 As a high-efficiency oil-immersed power transformer implementation method for protective components: a protective component is provided on the base plate 1. The protective component includes a support base 16, a support rod 17 and a protective plate 18.

[0037] A connecting rod 19 is connected to the support rod 17, and a protective net 20 is connected between the connecting rods 19.

[0038] Spikes 21 are installed on the protective net 20.

[0039] More specifically, during use, the support seats 16 evenly arranged on the outside of the device 2 provide support for the support rods 17, and the connecting rods 19 on the top of the rods provide support for the protective nets 20 connected to each other. The spikes 21 on the protective nets 20 serve as warnings, effectively preventing people from climbing over the protective plate 18 and touching the device 2, thus reducing the possibility of danger.

[0040] In summary, during the use or operation of the overall equipment: During use, the threaded cap 12 is removed by rotating along the thread of the oil injection pipe 11. Then, oil is injected into the oil injection cylinder 4 along the oil injection pipe 11. When it is necessary to extract oil from the oil injection cylinder 4 into the cylinder 3, the pump body 5 is activated to extract the oil from the oil injection cylinder 4 along the extraction pipe 6, and then it flows into the cylinder 3 along the connecting pipe 10, thus completing the use of the device 2 and facilitating the oil delivery process. Furthermore, during use, the motor 7 is activated to drive the stirring rod 9 at the output end to rotate, thereby driving the stirring roller 13 to fully mix the oil. Additionally, the rotating rod 14 is used to adjust the connected rotating plate 15, further ensuring thorough mixing of the oil. This ensures that the insulating oil entering the cylinder 3 at different times is fully mixed, maintaining a consistent temperature within the cylinder 3 and thus increasing the speed of insulating oil depressurization.

[0041] During use, the support seats 16 evenly arranged on the outside of the device 2 provide support for the support rods 17, and the connecting rods 19 on the top of the rods provide support for the protective nets 20 connected to each other. The spikes 21 on the protective nets 20 serve as warnings, effectively preventing people from climbing over the protective plate 18 and touching the device 2, thus reducing the possibility of danger.
