Description

Technical Field

[0001] The invention relates to the technical field of transformers, and in particular to a transformer with an active heat dissipation function. Background Art

[0002] The oil-immersed transformer is a voltage conversion device that uses oil cooling technology to reduce the transformer temperature to the minimum. It is placed in a welded steel tank filled with insulating oil. When the oil-immersed transformer is in operation, the heat of the coil and the iron core is first converted into insulating oil, which is then converted into a cooling medium. The oil-immersed transformer oil has good insulation and thermal conductivity. At the same time, the transformer oil is cheap and can solve the transformer's large-capacity heat dissipation and high-voltage insulation problems.

[0003] Oil-immersed transformers also have some disadvantages when in use, because the transformer inside the oil-immersed transformer has impurities and grease produced by the orderly operation of the transformer after long-term use, which will also deteriorate, resulting in the need to replace the transformer. Most oil-immersed transformers need to be shut down for maintenance when changing the oil, which will waste a lot of manpower and material resources and affect the production and operation of the transformer.

At the same time, the filter element 714 inside the filter box 7 can also be replaced after long-term use, thereby improving the filtering effect of the device and also cleaning the inside of the transformer.

[0030] When in use, the amount of transformer oil inside the transformer can be controlled by setting the transformer oil pillow 6, thereby playing a cooling role. When the external ambient temperature of the transformer is high, the transformer needs to be better cooled. At this time, the motor 9 can be driven to drive the screw 91 to rotate, and the surface of the screw 91 is equipped with an oil pressure plate 93, and the oil pressure plate 93 is arranged on the transformer oil in the transformer oil pillow 6. Under the action of the two limit rods 63, the oil pressure plate 93 can be driven to slide downward, thereby compressing the transformer oil inside the transformer oil pillow 6. The first output pipe 8 and the first input pipe 72 are arranged at the bottom of the transformer oil pillow 6. At this time, the transformer oil can be prevented from flowing due to the action of the first check valve 73 on the surface of the first input pipe 72, so that the transformer oil passes through The first output pipe 8 flows into the inside of the two second output pipes 81, and then flows into the transformer from the top through multiple connecting pipes 82 and multiple infusion holes 21. At the same time, under the action of the two balancing pipes 84, the pressure of the transformer oil pillow 6 and the inside of the transformer can be kept consistent, so that the amount of oil inside the transformer is increased, and the cooling effect inside the transformer is better. At the same time, in order to reduce the working temperature of the transformer, the two fans 5 on the surface of the transformer can be driven to drive the air to circulate. The air will pass through the surface of multiple heat-conducting strips 16, and then be blown out from the surface of multiple drainage pipes 4 through the action of the fans 5. The two ends of the multiple drainage pipes 4 are interconnected inside the transformer. At this time, the temperature inside the transformer can be cooled more quickly. When the ambient temperature on the surface of the transformer is When the temperature is relatively low, in order to keep the internal working environment temperature of the transformer from being greatly different, it can be protected by reducing the heat dissipation method. At this time, the motor 9 can be driven to drive the screw 91 to rotate. Under the action of the two limit rods 63, the oil pressure plate 93 can slide upward. At this time, the bottom of the transformer oil pillow 6 is connected to the first output pipe 8. Under the action of the second check valve 83 on its surface, the inside of the transformer is prevented from being connected with the inside of the transformer oil pillow 6. At this time, the transformer oil at the bottom of the transformer can flow into the inside of the transformer oil pillow 6 through the first input pipe 72 and the second input pipe 74. When the transformer oil flows, it will first enter the inside of the filter box 7 through the second input pipe 74, and the filter box 7 is installed with a filter element 714. Under the action of the filter element 714, the transformer oil can be Filtering can make the transformer oil purer, and the transformer oil will mix and bring out some impurities inside the transformer while flowing. Under the action of the filter element 714, the inside of the transformer can also be made cleaner, thereby improving the use effect of the device. Then, it enters the inside of the transformer oil pillow 6 through the first input pipe 72. Also under the action of the two balance pipes 84, the pressure inside the transformer and the transformer oil pillow 6 remains unchanged. At this time, the amount of oil inside the transformer can be reduced, thereby reducing the heat dissipation effect inside the transformer, thereby maintaining the temperature inside the transformer. After long-term use, the filter element 714 inside the filter box 7 can be replaced. When replacing the filter element 714, it is necessary to first close the stop valve 75 to prevent the transformer oil inside the transformer from leaking.Then, the sealing plug 715 is rotated to be taken out, and then the pull ring 711 is pulled to connect the connecting seat 79 and pulled out of the transverse groove 77. At this time, the filter element 714 can be taken out and replaced. After the new filter element 714 is replaced, it is installed and restored. Finally, the stop valve 75 is rotated to connect the second input pipe 74, so that it can be used continuously, thereby improving the use effect of the device and also increasing the service life of the device.
