Description

Technical Field

[0001] The present invention relates to the technical field of transformer heat dissipation, and more particularly to a heat dissipation device and a heat dissipation method for a high-voltage transformer. Background Art

[0002] A high-voltage transformer is a transformer that converts low voltage into high voltage through the principle of electromagnetic induction. It consists of an iron core and primary and secondary windings. High-voltage transformers generate a lot of heat during operation, so heat dissipation of high-voltage transformers is crucial. Oil-immersed transformers are widely used transformers with good heat dissipation effects. The oil tank shell that stores insulating oil can effectively protect and dissipate heat for high-voltage transformers.

[0003] Ordinary oil-immersed transformers have certain shortcomings when in use. In order to ensure good heat dissipation effect, it is generally necessary to dissipate heat from the insulating oil. A straight pipe is installed on the edge of the oil tank to facilitate heat dissipation of the insulating oil. In order to further improve the heat dissipation effect, an air-cooled radiator is also required. However, the insulating oil in the straight pipe tends to remain stationary for a long time, so the heat dissipation effect of the insulating oil inside the oil tank is poor. At the same time, the insulating oil will cause the temperature of the straight pipe to rise, thereby further limiting the heat dissipation effect. In order to further improve the heat dissipation effect, an insulating oil circulation device is generally set up, so a large number of electrical appliances are required, which will cause energy consumption and is not in line with the concept of green environmental protection.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0041] In the specific implementation, such as Figure 1 and Figure 2 As shown, the heat dissipation oil tank 2 is used to contain the winding core 1 and insulating oil for assisting the winding core 1 in dissipating heat.

[0042] In the specific implementation, such as Figures 1-4As shown, the heat dissipation assembly 3 is used to continuously dissipate heat for the insulating oil. Multiple heat dissipation assemblies 3 are evenly arranged on the front and rear sides of the heat dissipation mailbox. The heat dissipation assembly 3 includes an air cooling mechanism 4 and two guide pipe groups 5 that connect the upper and lower parts of the heat dissipation oil tank 2. The two guide pipe groups 5 are mirror-set. The air cooling mechanism 4 is installed on the heat dissipation oil tank 2 and the air cooling mechanism 4 is located outside the guide pipe group 5. The guide pipe group 5 includes a mounting shell 501, a guide pipe 502, a middle oil drain pipe 503 and a bottom oil drain pipe 504. The mounting shell 5 01 is installed on the outside of the heat dissipation oil tank 2, the upper end of the guide pipe 502 is installed on the outside of the installation shell 501, the middle oil drain pipe 503 and the bottom oil drain pipe 504 are arranged from top to bottom, the middle oil drain pipe 503 and the bottom oil drain pipe 504 are both installed between the guide pipe 502 and the heat dissipation oil tank 2, the insulating oil in the heat dissipation oil tank 2 enters the guide pipe 502 from the installation shell 501, and the insulating oil in the guide pipe 502 can flow back into the heat dissipation oil tank 2 from the middle oil drain pipe 503 and the bottom oil drain pipe 504.

[0043] In the specific implementation, such as Figure 9 As shown, the air cooling mechanism 4 includes a mounting frame 401, a chassis 402, a motor 403, a shaft 404 and fan blades 405. The mounting frame 401 is mounted on the heat dissipation oil tank 2 through a mounting rod, the chassis 402 is mounted on the rear side of the mounting frame 401, the motor 403 is mounted in the chassis 402, the shaft 404 is located in the mounting frame 401 and the shaft 404 is mounted on the output end of the motor 403, the fan blades 405 are mounted on the shaft 404, the motor 403 can drive the shaft 404 and the fan blades 405 to rotate, and the airflow generated by the fan blades 405 can be blown to the surface of the guide pipe group 5, thereby helping to dissipate heat.

[0044] In the specific implementation, such as Figure 3-Figure 7 As shown, the flow control component 6 is used to control the flow of insulating oil to improve the heat dissipation effect. The flow control component 6 is arranged on the side of the guide tube group 5.

[0045] In the specific implementation, such as Figure 3 and Figure 7As shown, the deceleration trigger 7 is used to trigger the flow control component 6. The deceleration trigger 7 is installed on the inner side of the air cooling mechanism 4 and is arranged on the inner side of the middle oil drain pipe 503. The deceleration trigger 7 includes a shell plate 701, a driving gear 702, a reduction gear 703 and a contact convex plate 704. The shell plate 701 is located above the upper linkage plate 6011 and is fixedly connected to the mounting frame 401 through a mounting support rod. The shaft 404 extends into the shell plate 701. The driving gear 702 is fixedly mounted on the end of the shaft 404. The reduction gear 703 is rotatably mounted on the inner wall of the shell plate 701 and the reduction gear 703 is meshed with the driving gear 702. The contact convex plate 704 is fixedly mounted on the reduction gear 703. When the air cooling mechanism 4 is operating, the shaft 404 can simultaneously drive the driving gear 702 to rotate. Since the reduction gear 703 is meshed with the driving gear 702, the driving gear 702 can drive the reduction gear 703 and the contact convex plate 704 to rotate.

[0046] Furthermore, the diameter of the reduction gear 703 is greater than the diameter of the driving gear 702 , so the speed of the contact convex plate 704 can be reduced by the reduction gear 703 .

[0047] Furthermore, Figure 5 and Figure 6As shown, the flow control assembly 6 includes a linkage frame 601, an oil discharge mechanism 602 and a limiter 603 for limiting the linkage frame 601. The linkage frame 601 includes an upper linkage plate 6011, a lower linkage plate 6012 and a linkage rod 6013. The upper linkage plate 6011 is located below the deceleration trigger 7 and the middle oil discharge pipe 503, the lower linkage plate 6012 is located below the guide pipe 502, the linkage rod 6013 is installed between the upper linkage plate 6011 and the lower linkage plate 6012, the limiter 603 is installed between the bottom oil discharge pipe 504 and the upper linkage plate 6011, the oil discharge mechanism 602 is arranged in the guide pipe, and the oil discharge mechanism 602 includes an upper movable plate 6021, a lower fixed plate 6022 and a control rod 6023. The lower fixed plate 6022 is installed on the inner wall of the guide tube and is located below the water level of the middle oil discharge pipe 503. The upper movable plate 6021 is located above the lower fixed plate 6022. An upper circulation hole group 8 is formed on the upper movable plate 6021, and an upper sealing rod group 9 is installed below the upper movable plate 6021. A lower circulation hole group 10 is formed on the lower fixed plate 6022, and a lower sealing rod group 11 is installed above the lower fixed plate 6022. The upper circulation hole group 8 corresponds to the lower sealing rod group 11, and the upper sealing rod group 9 corresponds to the lower circulation hole group 10. The control rod 6023 is installed between the upper movable plate 6021 and the lower linkage plate 6012, and the control rod 6023 is passed through the lower fixed plate 6022 and the bottom of the guide tube 502. When the air cooling mechanism 4 is in operation, the contact convex plate 704 of the deceleration actuator 7 can rotate at the same time. When the protruding part of the contact convex plate 704 contacts the upper linkage plate 6011, it can push it downward, and at the same time, it can push the linkage rod 6013 and the lower linkage rod 6013 downward. When the lower linkage plate 6012 moves downward, it can drive the control rod 6023 to move downward. The control rod 6023 can pull the upper movable plate 6021 in the guide tube 502 to move downward. When the upper movable plate 6021 moves downward until the upper sealing rod group 9 is inserted into the lower circulation hole group 10 and the lower sealing rod group 11 is inserted into the upper circulation hole group 8, only the middle oil drain pipe 503 between the upper movable plate 6021 and the lower fixed plate 6022 is connected to the heat dissipation oil tank 2. Therefore, under the action of hydraulic pressure, the insulating oil between the upper movable plate 6021 and the lower fixed plate 6022 can be quickly sprayed into the heat dissipation oil tank 2 through the middle oil drain pipe 503. At the same time, the insulating oil in the heat dissipation oil tank 2 can quickly pass through the mounting shell 501 into the guide pipe group 5, so that the insulating oil in the heat dissipation oil tank 2 can continue to flow, thereby ensuring a good heat dissipation effect of the insulating oil.

[0048] Furthermore, Figure 8As shown, the limiter 603 includes a fixed sleeve 6031, a pressure relief rod 6032, a limiting gasket 6033 and a limiting spring 6034. The fixed sleeve 6031 is installed above the bottom oil drain pipe 504, the pressure relief rod 6032 is installed at the bottom of the upper linkage plate 6011 and the bottom of the pressure relief rod 6032 is passed through the fixed sleeve 6031, the limiting gasket 6033 is installed at the bottom of the pressure relief rod 6032 and the limiting gasket 6033 is clamped in the fixed sleeve 6031, and the limiting spring 6034 is installed at the bottom of the pressure relief rod 6032. Installed between the limit gasket 6033 and the inner wall of the fixed sleeve 6031, the limit spring 6034 is in a normal state when the deceleration trigger 7 is not in contact with the upper linkage plate 6011, so it can support the upper linkage plate 6011 through the buffer rod 6032. When the protruding part of the contact cam 704 of the deceleration trigger 7 contacts the upper linkage plate 6011, the buffer rod 6032 can squeeze the limit spring 6034 and move downward, so that the limiter 603 can limit the linkage frame 601.

[0049] In this embodiment, the guide pipe group 5 can be used to connect the insulating oil in the heat dissipation oil tank 2 up and down. When the insulating oil passes through the guide pipe group 5, it can dissipate heat by heat conduction. At the same time, the guide pipe group 5 can be directly blown by the air cooling component, thereby further improving the heat dissipation effect. The motor 403 can drive the shaft 404 and the fan blades 405 to rotate, so that the air flow generated by the fan blades 405 can blow to the surface of the guide pipe group 5, thereby helping to dissipate heat. At the same time, the shaft 404 can drive the driving gear 702 to rotate. Since the reduction gear 703 is meshed with the driving gear 702, the driving gear 702 can drive the reduction gear 703 and the contact convex plate 704 to rotate. When the protruding part of the contact convex plate 704 contacts the upper linkage plate 6011, it can push it downward, and at the same time, the linkage rod 6013 and the lower linkage rod 60 13 is pushed downward, and when the lower linkage plate 6012 moves downward, it can drive the control rod 6023 to move downward, and the control rod 6023 can pull the upper movable piece 6021 in the guide tube 502 to move downward. When the upper movable piece 6021 moves downward until the upper sealing rod group 9 is inserted into the lower circulation hole group 10 and the lower sealing rod group 11 is inserted into the upper circulation hole group 8, only the middle oil drain pipe 503 between the upper movable piece 6021 and the lower fixed piece 6022 is connected with the heat dissipation oil tank 2. Therefore, under the action of hydraulic pressure, the insulating oil between the upper movable piece 6021 and the lower fixed piece 6022 can be quickly sprayed into the heat dissipation oil tank 2 through the middle oil drain pipe 503, and at the same time, the insulating oil in the heat dissipation oil tank 2 can quickly pass through the mounting shell 501 into the guide pipe group 5, so that the insulating oil in the heat dissipation oil tank 2 can continue to flow, thereby ensuring a good heat dissipation effect of the insulating oil.

[0055] In the specific implementation, such as Figure 3-Figure 7 As shown, the flow control component 6 is used to control the flow of insulating oil to improve the heat dissipation effect. The flow control component 6 is arranged on the side of the guide tube group 5.

[0056] In the specific implementation, such as Figure 3 and Figure 7As shown, the deceleration trigger 7 is used to trigger the flow control component 6. The deceleration trigger 7 is installed on the inner side of the air cooling mechanism 4 and is arranged on the inner side of the middle oil drain pipe 503. The deceleration trigger 7 includes a shell plate 701, a driving gear 702, a reduction gear 703 and a contact convex plate 704. The shell plate 701 is located above the upper linkage plate 6011 and is fixedly connected to the mounting frame 401 through a mounting support rod. The shaft 404 extends into the shell plate 701. The driving gear 702 is fixedly mounted on the end of the shaft 404. The reduction gear 703 is rotatably mounted on the inner wall of the shell plate 701 and the reduction gear 703 is meshed with the driving gear 702. The contact convex plate 704 is fixedly mounted on the reduction gear 703. When the air cooling mechanism 4 is operating, the shaft 404 can simultaneously drive the driving gear 702 to rotate. Since the reduction gear 703 is meshed with the driving gear 702, the driving gear 702 can drive the reduction gear 703 and the contact convex plate 704 to rotate.

[0057] Furthermore, the diameter of the reduction gear 703 is greater than the diameter of the driving gear 702 , so the speed of the contact convex plate 704 can be reduced by the reduction gear 703 .

[0058] Furthermore, Figure 5 and Figure 6As shown, the flow control assembly 6 includes a linkage frame 601, an oil discharge mechanism 602 and a limiter 603 for limiting the linkage frame 601. The linkage frame 601 includes an upper linkage plate 6011, a lower linkage plate 6012 and a linkage rod 6013.

The lower fixed plate 6022 is installed on the inner wall of the guide tube and is located below the water level of the middle oil discharge pipe 503. The upper movable plate 6021 is located above the lower fixed plate 6022. An upper circulation hole group 8 is formed on the upper movable plate 6021, and an upper sealing rod group 9 is installed below the upper movable plate 6021.

When the air cooling mechanism 4 is in operation, the contact convex plate 704 of the deceleration actuator 7 can rotate at the same time. When the protruding part of the contact convex plate 704 contacts the upper linkage plate 6011, it can push it downward, and at the same time, it can push the linkage rod 6013 and the lower linkage rod 6013 downward. When the lower linkage plate 6012 moves downward, it can drive the control rod 6023 to move downward. The control rod 6023 can pull the upper movable plate 6021 in the guide tube 502 to move downward. When the upper movable plate 6021 moves downward until the upper sealing rod group 9 is inserted into the lower circulation hole group 10 and the lower sealing rod group 11 is inserted into the upper circulation hole group 8, only the middle oil drain pipe 503 between the upper movable plate 6021 and the lower fixed plate 6022 is connected to the heat dissipation oil tank 2. Therefore, under the action of hydraulic pressure, the insulating oil between the upper movable plate 6021 and the lower fixed plate 6022 can be quickly sprayed into the heat dissipation oil tank 2 through the middle oil drain pipe 503. At the same time, the insulating oil in the heat dissipation oil tank 2 can quickly pass through the mounting shell 501 into the guide pipe group 5, so that the insulating oil in the heat dissipation oil tank 2 can continue to flow, thereby ensuring a good heat dissipation effect of the insulating oil.

[0059] Furthermore, Figure 8As shown, the limiter 603 includes a fixed sleeve 6031, a pressure relief rod 6032, a limiting gasket 6033 and a limiting spring 6034. The fixed sleeve 6031 is installed above the bottom oil drain pipe 504, the pressure relief rod 6032 is installed at the bottom of the upper linkage plate 6011 and the bottom of the pressure relief rod 6032 is passed through the fixed sleeve 6031, the limiting gasket 6033 is installed at the bottom of the pressure relief rod 6032 and the limiting gasket 6033 is clamped in the fixed sleeve 6031, and the limiting spring 6034 is installed at the bottom of the pressure relief rod 6032. Installed between the limit gasket 6033 and the inner wall of the fixed sleeve 6031, the limit spring 6034 is in a normal state when the deceleration trigger 7 is not in contact with the upper linkage plate 6011, so it can support the upper linkage plate 6011 through the buffer rod 6032. When the protruding part of the contact cam 704 of the deceleration trigger 7 contacts the upper linkage plate 6011, the buffer rod 6032 can squeeze the limit spring 6034 and move downward, so that the limiter 603 can limit the linkage frame 601.

[0060] In the specific implementation, such as Figure 3 As shown, a cut-off assembly 12 is provided in the mounting shell 501. The cut-off assembly 12 is used to block the insulating oil in the heat dissipation oil tank 2 from entering the guide pipe 502 when the flow control assembly 6 is triggered, so that the upper part of the guide pipe 502 forms a hollow state, thereby improving the heat dissipation effect.

[0061] Furthermore, the shut-off assembly 12 includes a stopper 1201 and a connecting bent rod 1202. The stopper 1201 is arranged in the mounting shell 501 and corresponds to the upper port of the guide tube 502. The connecting bent rod 1202 is installed between the stopper 1201 and the upper linkage plate 6011 and the connecting bent rod 1202 is passed through the mounting shell 501.

[0062] Preferably, gaps are left between the stopper 1201 and the inner walls on both sides of the mounting shell 501, so that the insulating oil in the mounting shell 501 can flow adaptively.

After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
