Description

Technical Field

[0001] The present invention belongs to the technical field of self-cooling transformers, and specifically relates to an automatic cooling transformer. Background Art

[0002] Intelligent large oil-immersed transformers improve the insulation performance between electrical components and the outside world by immersing electrical components such as iron cores and windings in transformer oil, optimize the heat transfer and dissipation performance of heat-dissipating electrical components, and can also well protect the iron core and windings from the influence of moisture in the air. A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. During the use of the transformer, the heat dissipation efficiency is poor, which easily affects the service life.

[0003] A patent with the publication number CN116092788 discloses an oil-immersed transformer with automatic heat dissipation, belonging to the technical field of transformers. It includes an oil tank, and a first heat dissipation structure and a second heat dissipation structure are arranged on the side wall of the oil tank. The first heat dissipation structure includes a number of first heat dissipation pipes arranged in parallel on the outer side surface of the oil tank, and the second heat dissipation structure includes a number of second heat dissipation pipes arranged in parallel on the outer side surface of the oil tank. One end of each first heat dissipation pipe communicates with the inner cavity of the oil tank, and the other end of each first heat dissipation pipe is connected in parallel to a main collecting pipe. One end of each second heat dissipation pipe communicates with the inner cavity of the oil tank, and the other end of each second heat dissipation pipe is connected in parallel to a second main collecting pipe; it also includes an oil barrel, and a piston plate is slidably connected along the axis of the oil barrel in the oil barrel. The piston plate divides the oil barrel into an oil inlet cavity and an oil return cavity. The oil inlet cavity is communicated with the first main collecting pipe, the oil return cavity is communicated with the second main collecting pipe, and a telescopic guide rod connecting the piston plate and the inner wall surface of the oil barrel is arranged in the oil return cavity. The present invention has the advantages of high heat dissipation efficiency, etc.

[0004] Currently, in the existing technology, intelligent large transformers all adopt the oil-immersed cooling method. However, the low-temperature cooling oil will become a heat source after absorbing the heat source. The existing method of cooling the hot oil is to use the outer shell of the intelligent large transformer for blade heat dissipation, or to pass a pipeline through the inside of the cooling oil and blow air at one end of the pipeline by a fan to cool the temperature inside the pipeline. Since there is no external force acting on the cooling oil inside the intelligent large transformer, the cooling oil will be in a static state inside the transformer. And air cooling can only cool the cooling oil near the edge of the outer shell of the intelligent large transformer and around the pipeline. The cooling oil at some relatively far positions and around the heating elements cannot be effectively cooled, and can only be cooled by the heat source interaction between the cooling oils. This cooling method is relatively slow and the cooling efficiency is relatively low.

[0005] Therefore, the present invention provides an automatic cooling transformer. Summary of the Invention

[0010] Preferably, a return pipe is fixedly connected to one side edge position at the top of the cooling box. A drainage pipe is fixedly connected to the bottom surface of the cooling box. A water pump is arranged at the other end of the drainage pipe.

[0011] Preferably, one ends of the water pump and the return pipe extend to the inner wall surface of the intelligent large transformer. Two heat absorption boxes are respectively fixedly installed on one end of the return pipe and the output end of the water pump.

[0012] Preferably, the circulation oil pipe is arranged on the inner wall surface of the heat absorption box. One end of the circulation oil pipe is fixedly connected to the outer surface of the iron core winding. One ends of the two circulation oil pipes pass through the transformer oil transmission tank and respectively extend to the inner wall surfaces of the upper oil cavity and the lower oil cavity.

[0014] Preferably, a support frame 1 is fixedly connected to the outer surface of the transformer oil tank, a transmission rod is movably sleeved on the inner wall of the support frame 1, and a transmission track arranged on the outer surface of the limit groove ring is movably sleeved on the output end of the motor.

[0017] The beneficial effects of the present invention are as follows: 1. In the automatic heat dissipation transformer described in the present invention, when the lower pressure plate moves downward, the cooling oil in the lower oil chamber will be injected into the core winding through the circulating oil pipe; at this time, the upper oil chamber will present a semi-vacuum state, and another circulating oil pipe will draw the cooling oil into the upper oil chamber; when the lower pressure plate moves upward, the cooling oil will flow back in the opposite direction along the circulating oil pipe to the outer surface of the core winding, and the circulating oil pipe will be used to circulate and guide the cooling oil back and forth, thereby achieving the effect of repeated drainage of the cooling oil; 2. When the cooling oil enters the core winding, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. The fluidity of the hot oil is higher than that of the low-temperature cooling oil. Under the impact of the low-temperature cooling oil, the hot oil will quickly diffuse from the surface of the heating element to the surrounding area. The flowing low-temperature cooling oil will hit the surface of the heating element. The high temperature difference will quickly absorb the heat source from the surface of the heating element. The impacted cooling oil will mix with the heat-absorbing hot oil, and the hot oil around the heating element will be quickly cooled down. 3. For the automatic heat dissipation transformer of the present invention, when the lower pressing plate moves downward, hot oil inside the iron core winding is absorbed through another circulating oil pipe. Utilizing the height difference between the two circulating oil pipes, each time cooling oil is extracted, the cooling oil that previously entered the iron core winding can be absorbed. With the absorption and release of the cooling oil, the cooling oil on the surface of the iron core winding is continuously stirred, dispersing the hot oil that has absorbed heat sources around the heating elements, keeping the area around the heating elements at a low temperature all the time, and thus maintaining the effect of being in the best absorption state. 4. For the automatic heat dissipation transformer of the present invention, when the cooling oil circulates, a water pump is used to absorb low-temperature coolant inside the diversion pipe. The flowing low-temperature coolant fills the inside of the heat absorption box. Utilizing the heat conduction characteristics of the circulating oil pipe, heat interaction is carried out between the heat source inside the circulating oil pipe and the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box flows rapidly through the diversion pipe and the return pipe, keeping the temperature inside the heat absorption box at a relatively low level all the time.

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 9 shown, an automatic heat dissipation type transformer according to an embodiment of the present invention includes an intelligent large transformer 11 and an anti-collision housing 12 detachably installed on both side edges of the intelligent large transformer 11. Two groups of transformer oil transmission tanks 121 are fixedly installed on the upper and lower inner wall surfaces of the anti-collision housing 12. A motor 125 is fixedly installed on the inner bottom wall surface of the anti-collision housing 12. A transmission extrusion rod a2 is movably sleeved on the inner wall surface of the transformer oil transmission tank 121. Lower pressing plates a4 are fixedly installed at both ends of the transmission extrusion rod a2. Upper oil cavity a5 and lower oil cavity a6 are respectively arranged on the inner wall surface of the transformer oil transmission tank 121. Two circulating oil pipes 139 are fixedly installed on the outer surface of the transformer oil transmission tank 121. The inside of the transformer oil transmission tank 121 is filled with low-temperature cooling oil; a rectangular limiting strip a3 is fixedly installed on the outer surface of the transmission extrusion rod a2 and at the middle position. A push rod 128 is movably sleeved on the inner wall surface of the rectangular limiting strip a3. An eccentric rotating disk 127 is fixedly connected to the outer surface of the push rod 128.

[0023] The motor 125 drives the eccentric rotating disk 127 to rotate. When the eccentric rotating disk 127 rotates, it drives the push rod 128 to rotate. As the outer surface of the push rod 128 slides on the inner wall of the rectangular limit strip a3, the rectangular limit strip a3 is pushed, so that the rectangular limit strip a3 maintains a horizontal angle and moves up and down along the surface of the eccentric rotating disk 127. As the push rod 128 moves inside the rectangular limit strip a3, the lower pressure plate a4 on the upper and lower surfaces of the rectangular limit strip a3 is driven to move up and down on the inner wall of the anti-collision sleeve 12. When the lower pressure plate a4 moves toward the lower oil chamber a6, the cooling oil inside the lower oil chamber a6 is injected into the outer surface of the core winding 1311 through the circulating oil pipe 139; when the lower pressure plate a4 is pressed down, the upper oil chamber a6 is pressed down. The interior of a5 will present a semi-vacuum state, and then the cooling oil will be drawn into the interior of the upper oil chamber a5 through another circulating oil pipe 139. When the lower pressure plate a4 starts to move upward, the cooling oil filled in the upper oil chamber a5 will flow back into the interior of the iron core winding 1311 in the opposite direction along the circulating oil pipe 139. When the cooling oil enters the interior of the iron core winding 1311, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. The fluidity of the hot oil is higher than that of the low-temperature cooling oil. Under the impact of the low-temperature cooling oil, the hot oil will quickly diffuse from the surface of the heating element to the surrounding area. When the low-temperature cooling oil hits the surface of the heating element, the higher temperature difference will quickly absorb the heat source from the surface of the heating element. The impacted cooling oil will mix with the hot oil after absorbing heat, and the hot oil around the heating element will be quickly cooled down. The transformer oil tank 121 is used to circulate and extract the cooling oil, and the lower pressure plate a4 is used to squeeze and extract the cooling oil, so that the cooling oil impacts the inside of the core winding 1311, and the cooling oil in a static state is stirred, so that the hot oil can flow everywhere, and then the hot oil and the low-temperature cooling oil can be quickly mixed together. With the flow of the low-temperature cooling oil, the area around the heating element can be kept at a low temperature. The coolant is used to absorb heat and cool the hot oil in the circulating oil pipe 139, and the fan is used to quickly cool the coolant.

[0024] like Figures 1 to 9As shown, a first support frame 122 is fixedly connected to the outer surface of the transformer oil tank 121. A transmission rod 123 is movably sleeved on the inner wall surface of the first support frame 122. The two ends of the transmission rod 123 are respectively fixedly connected to the outer surface of an eccentric rotating disk 127. A limiting groove ring 124 is fixedly connected to the outer surface of the transmission rod 123 and located at both side edge positions. A transmission track 126 is movably sleeved on the output end of the motor 125 and arranged on the outer surface of the limiting groove ring 124. A sealing sleeve ring a1 is fixedly installed on the inner wall surface of the transformer oil tank 121. The outer surface of the transmission extrusion rod a2 is movably lapped on the inner wall surface of the sealing sleeve ring a1.

[0025] When the cooling oil in the lower oil chamber a6 enters the iron core winding 1311, when the lower pressing plate a4 moves down, the hot oil inside the iron core winding 1311 is absorbed through another circulation oil pipe 139. By using the height difference between the two circulation oil pipes 139, each time the cooling oil is pumped, the cooling oil that previously entered the iron core winding 1311 can be absorbed. When the hot oil is drained into the upper oil chamber a5, the cooling liquid cools the hot oil. During the absorption and pumping of the cooling oil, the cooling oil inside the iron core winding 1311 is continuously stirred, dispersing the hot oil that has absorbed the heat source around the heating element, keeping the area around the heating element at a low temperature all the time, enabling the heating element to always be at a relatively large temperature difference and always maintaining the best absorption state.

[0026] As Figure 1 - Figure 2 and Figures 5 to 8 As shown in FIGS. - and -, a return pipe 1310 is fixedly connected to the top side edge position of the cooling tank 132. A drainage pipe 136 is fixedly connected to the bottom surface of the cooling tank 132. A water pump 137 is arranged at the other end of the drainage pipe 136. One ends of the water pump 137 and the return pipe 1310 extend to the inner wall surface of the intelligent large transformer 11. Two heat absorption boxes 138 are respectively fixedly installed on one end of the return pipe 1310 and the output end of the water pump 137. The circulation oil pipe 139 is arranged on the inner wall surface of the heat absorption box 138. One end of the circulation oil pipe 139 is fixedly connected to the outer surface of the iron core winding 1311. One ends of the two circulation oil pipes 139 pass through the transformer oil tank 121 and extend to the inner wall surfaces of the upper oil chamber a5 and the lower oil chamber a6 respectively. The iron core winding 1311 is arranged on the inner wall surface of the intelligent large transformer 11.

[0027] When the cooling oil circulates, the internal part of the drainage pipe 136 is sucked with low-temperature coolant by the water pump 137. The flowing low-temperature coolant will fill the inside of the heat absorption box 138. Utilizing the heat conduction characteristic of the circulation oil pipe 139, the heat source inside the circulation oil pipe 139 is thermally interacted with the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box 138 will flow rapidly through the drainage pipe 136 and the return pipe 1310, so that the temperature inside the heat absorption box 138 is always kept at a relatively low temperature; Since the surface of the circulation oil pipe 139 is always at a relatively low temperature, and when the temperature difference between the inner wall surface of the circulation oil pipe 139 and the hot oil is large, rapid thermal interaction will occur, so that the hot oil can be rapidly cooled when flowing, so that the cooling oil entering the iron core winding 1311 can always be kept in the best low-temperature state.

[0028] Such as Figures 1 to 2 and Figure 8 - Figure 9 As shown, on the front and back surfaces of the intelligent large transformer 11, transformer heat dissipation grooves 113 are provided. On the top surface of the intelligent large transformer 11 and at the positions of the two side edges, high-voltage side bushings 112 are fixedly installed. On the bottom surface of the intelligent large transformer 11, a support base 111 is fixedly installed. On the outer surface of the second support frame 13, a support block is fixedly connected, and on the outer surface of the support block, it is fixedly connected to the outer surface of the air collecting box 134.

[0029] Cooperate with the transformer heat dissipation grooves 113 on the outer surface of the intelligent large transformer 11 to increase the contact area and range with the outside world. At the same time, cooperate with the transformer heat dissipation grooves 113 to absorb and transfer the heat source inside the intelligent large transformer 11. When the natural wind source blows on the surface of the transformer heat dissipation grooves 113, the wind source will take away the waste heat on the surface of the transformer heat dissipation grooves 113, and then dissipate the waste heat inside the intelligent large transformer 11 for temperature reduction treatment.

[0030] Such as Figures 1 to 4 and Figure 7 - Figure 9 As shown, on the back of the intelligent large transformer 11, a second support frame 13 is fixedly installed. On the outer surface of the top of the second support frame 13, an arc-shaped support seat 131 is fixedly installed. On the outer surface of the top of the arc-shaped support seat 131, a cooling box 132 is detachably installed. On the inner side wall surface of the cooling box 132, a condensing copper pipe 133 is fixedly connected, and both ends of the condensing copper pipe 133 respectively pass through the cooling box 132 and extend to the outer surface. On the bottom surface of the cooling box 132 and at the receiving end of the condensing copper pipe 133, an air collecting box 134 is fixedly connected. On the inner side wall surface of the air collecting box 134, a blower 135 is fixedly connected. On the other end of the circulation oil pipe 139, an iron core winding 1311 is fixedly installed.

[0031] After absorbing the heat source, the coolant enters the cooling box 132 through the return pipe 1310, and cooperates with the condensing copper tube 133 inside the cooling box 132 to absorb the heat source inside the coolant. At this time, the blower 135 inside the wind collecting box 134 is blown. The gas absorbed by multiple blowers 135 will quickly accumulate inside the wind collecting box 134, and the air gradually accumulated inside the wind collecting box 134 will be compressed. The compressed gas will flow rapidly through the inner wall of the condensing copper tube 133. When the cold air flows rapidly, it will take away the heat source inside the condensing copper tube 133 and discharge the hot air. After the gas flows rapidly and is discharged, the inner wall of the condensing copper tube 133 is always in a state of thermal interaction, which greatly accelerates the cooling effect of the coolant.

[0032] Working principle: when the lower pressure plate a4 moves toward the lower oil chamber a6, the cooling oil in the lower oil chamber a6 will be injected into the outer surface of the core winding 1311 through the circulating oil pipe 139. When the cooling oil enters the core winding 1311, the impact of the cooling oil will impact the cooling oil accumulated around the heating element. The fluidity of the hot oil is higher than that of the low-temperature cooling oil. Under the impact of the low-temperature cooling oil, the hot oil will quickly diffuse from the surface of the heating element to the surrounding area. When the low-temperature cooling oil hits the surface of the heating element, the higher temperature difference will quickly absorb the heat source from the surface of the heating element. The impacted cooling oil will mix with the heat-absorbing hot oil, and the hot oil around the heating element will be quickly cooled down. When the cooling oil in the lower oil chamber a6 enters the core winding 1311, the lower pressure plate a4 moves downward to absorb the hot oil in the core winding 1311 through another circulating oil pipe 139. By utilizing the height difference between the two circulating oil pipes 139, each time the cooling oil is extracted, the cooling oil previously entering the core winding 1311 can be absorbed. When the hot oil flows into the upper oil chamber a5, the coolant will cool the hot oil. Under the absorption and collection of the cooling oil, the cooling oil in the core winding 1311 will be continuously stirred, and the hot oil around the heating element that has absorbed the heat source will be dispersed, so that the surrounding area of the heating element is always kept in a low temperature state, so that the heating element can be always in a high temperature difference, and the effect of always maintaining the best absorption state is achieved. When the cooling oil circulates, the water pump 137 is used to absorb the low-temperature coolant inside the drainage pipe 136. The flowing low-temperature coolant will fill the inside of the heat absorption box 138. The heat conductivity of the circulating oil pipe 139 is used to make the heat source inside the circulating oil pipe 139 interact with the low-temperature coolant outside. The low-temperature coolant inside the heat absorption box 138 will flow quickly through the drainage pipe 136 and the return pipe 1310, so that the temperature inside the heat absorption box 138 is always kept at a low temperature. Since the surface of the circulating oil pipe 139 is always at a relatively low temperature, when the temperature difference between the inner wall of the circulating oil pipe 139 and the hot oil is large, thermal interaction will occur quickly, so that the hot oil can be cooled quickly when flowing, so that the cooling oil entering the core winding 1311 can always be kept at an optimal low temperature state; After absorbing the heat source, the coolant enters the cooling box 132 through the return pipe 1310. The shape of the condensing copper tube 133 inside the cooling box 132 increases the contact area and range with the coolant, thereby absorbing the heat source inside the coolant in a large range. At this time, the blower 135 inside the air collecting box 134 is blown. The gas absorbed by the multiple blowers 135 will quickly accumulate inside the air collecting box 134. The air gradually accumulated inside the air collecting box 134 will be compressed. The compressed gas will flow quickly through the inner wall of the condensing copper tube 133. When the cold air flows quickly, it will take away the heat source inside the condensing copper tube 133 and discharge the hot air. As the gas flows quickly and is discharged, the inner wall of the condensing copper tube 133 is always in a state of thermal interaction, which greatly accelerates the cooling effect of the coolant. The transformer oil tank 121 is used to circulate and extract the cooling oil, and the lower pressure plate a4 is used to squeeze and extract the cooling oil, so that the cooling oil impacts the inside of the core winding 1311, and the cooling oil in a static state is stirred, so that the hot oil can flow everywhere, and then the hot oil and the low-temperature cooling oil can be quickly mixed together. With the flow of the low-temperature cooling oil, the area around the heating element can be kept at a low temperature. At the same time, the low-temperature coolant in the cooling box 132 is used to cool the hot oil, and the coolant is used to absorb heat and cool the hot oil in the circulating oil pipe 139. At the same time, the fan is used to quickly cool the coolant.
