Description

Technical Field

[0001] The invention belongs to the technical field of high and low voltage power transmission transformers, and in particular relates to a power supply transformer device for high and low voltage power transmission networks. Background Art

[0002] Due to the inherent characteristics and usage of the high and low voltage transmission network power supply transformer, it will face a variety of usage situations when it is used, but it is not limited to the one proposed below. More specifically, especially the iron core and winding are arranged inside it, which will generate heat when working, and the conventional heat dissipation method is to immerse the iron core and winding in transformer oil, and through the natural convection effect of the transformer oil, the heat generated therein is continuously driven to the outside of the transformer, and the heat is dissipated through the effect of heat conduction.

[0003] Conventional transformers mainly use two methods to dissipate heat in the external circulation: natural dissipation and forced air cooling. Although these two methods have a certain heat exchange effect, they are only suitable for situations where the external temperature difference is large. When the external temperature is high, neither natural dissipation nor forced air cooling is sufficient to obtain more natural cooling, resulting in poor circulation and heat dissipation effect of transformer oil, which makes it difficult for the heat generated inside the transformer to begin to dissipate.

[0004] Combining the above-mentioned problem entry points, it is found that it is difficult to avoid the above-mentioned problems when the existing high and low voltage transmission network power supply transformers on the market are in use, and thus it is impossible to achieve the desired effect. Therefore, we propose a power supply transformer equipment for high and low voltage transmission networks, which can perform cold compensation when the transformer oil is circulated and dissipated outside the transformer during use, thereby increasing the heat dissipation rate of the transformer oil, and further allowing the heat inside the transformer to be quickly dissipated. Summary of the invention

[0005] The purpose of the present invention is to provide a power supply transformer device for an existing high and low voltage transmission network. The device has the advantage that by setting a heat dissipation pipe and a cold capacity compensation component for use, the heat dissipation pipe can facilitate the circulation of transformer oil. The transformer oil rises to the oil level surface due to the high heat and enters the heat dissipation pipe, so that the heat taken away by the transformer oil is heat exchanged with the external air intake. At the same time, the cold capacity compensation component can compensate for the cold capacity of the external air intake when the temperature is high in the natural environment, so that a large temperature difference can be obtained, so that the heat of the transformer oil can be quickly exchanged with the external air intake, so that when the transformer oil circulates into the transformer body, it can quickly take away the heat generated by the iron core and winding in the transformer body, thereby ensuring the stable operation of the transformer body.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A power supply transformer device for a high and low voltage transmission network, comprising a transformer body, a mounting shell is mounted on the surface of the transformer body, a fan structure for air intake and air outlet is bolted on both sides of the mounting shell, a heat dissipation mechanism is bolted inside the mounting shell, and the heat dissipation mechanism is connected to the transformer body on a side close to the transformer body; The heat dissipation mechanism includes a plurality of heat dissipation pipes, the heat dissipation pipes are evenly connected to the surface of the transformer body, and are connected to the transformer body on the side close to the transformer body, the heat dissipation pipes run through the interior of the mounting shell, and a cold compensation component is bolted to the right side of the interior of the mounting shell, and the cold compensation component is used in conjunction with the heat dissipation pipes; The cooling capacity compensation component includes a pre-cooling part, which is bolted to the front side of the installation shell. A distribution part is bolted to the right side of the pre-cooling part, and the distribution part is used in conjunction with the right fan structure.

[0007] By adopting the above technical scheme, by setting up the cooperation of the heat dissipation pipe and the cold capacity compensation component, the heat dissipation pipe can facilitate the circulation of the transformer oil. The transformer oil rises to the oil level surface due to the high heat and enters the heat dissipation pipe, so that the heat taken away by the transformer oil is heat-exchanged with the external air intake. At the same time, the cold capacity compensation component can compensate the cold capacity of the external air intake when the temperature is high in the natural environment, so that a large temperature difference can be obtained, so that the heat of the transformer oil can be quickly exchanged with the external air intake, so that when the transformer oil circulates into the transformer body, it can quickly take away the heat generated by the iron core and winding in the transformer body, thereby ensuring the stable operation of the transformer body.

[0009] By adopting the above technical solution, a heat dissipation pipe is provided, and the transformer oil rises to the oil level surface due to high heat, and enters the connecting pipe and the retarding pipe. The staggered spacer blocks slow down the flow rate of the transformer oil in the retarding pipe, and extend the flow time of the transformer oil in the outside world, thereby expanding the heat conduction effect of the heat-conducting fins on the transformer oil, greatly improving the heat dissipation effect of the transformer oil, and the setting of the interception net can also intercept impurities contained in the transformer oil, so as to achieve the purification effect of the transformer oil.

[0010] The present invention is further configured as follows: the spacer blocks are evenly and staggeredly distributed inside the retarder tube along the axis of the retarder tube, and the interior of the spacer blocks is hollow.

[0011] By adopting the above technical solution, by arranging spacer blocks evenly distributed inside the retarder tube along the axis of the retarder tube, and the interior of the spacer blocks is hollow, the flow rate of the transformer oil in the outside world can be delayed and the heat dissipation effect can be improved.

[0013] By adopting the above technical solution, a pre-cooling component is set up, and the external air entering the installation shell will be distributed in the channel formed by the adjacent baffles under the action of the distribution component. At the same time, the fluid pipeline is connected to the external cold water, so that the slow-release sponge absorbs and stores the cold water, so that the cold water is pre-cooled with the external air to achieve the effect of cold capacity compensation, and the moisture contained in the air is removed through the dehumidification plate. Therefore, when the pre-cooled external air comes into contact with the transformer oil, the heat exchange effect can be increased, thereby improving the heat dissipation effect of the transformer oil.

[0014] The present invention is further configured as follows: the baffles are stacked and equidistantly distributed between opposite sides of two partitions, and the baffles are orifice plate structures.

[0015] By adopting the above technical solution, the baffles are stacked and evenly distributed between the opposite sides of the two partitions, and the baffles are orifice plates, which can facilitate the formation of multiple fluid channels and slow down the flow rate of the external air so that the external air can be fully pre-cooled.

[0017] By adopting the above technical solution, by setting up a distribution piece, under the traction of the fan structure, the external air enters through the right wind hole through the rotating disk, and passes through the left wind hole through the fixed disk to enter the interior of the pre-cooling part. At the same time, under the action of wind force, the deceleration part can slowly drive the rotating disk to rotate, so that the air holes on both sides are connected and separated, and the external air can be evenly distributed inside the pre-cooling part. Therefore, the external air can be fully pre-cooled in the pre-cooling part, thereby improving the subsequent heat exchange effect.

[0018] The present invention is further configured as follows: a connecting hole for use with the left air hole is provided in a ring shape on the right side of the right partition plate, and the connecting hole corresponds to the left air hole one by one.

[0019] By adopting the above technical solution, by setting the connecting holes, and the connecting holes corresponding to the left air holes one by one, it is possible to form an external air intake flow channel, thereby facilitating the transportation of the external air intake.

[0021] By adopting the above technical solution, by setting up a deceleration part, the fan blades can be driven to rotate under the action of wind, thereby synchronously making the connecting shaft drive its surface gear to rotate, and under the meshing connection of the two gears, the top gear drives the rotating shaft to rotate, thereby achieving the effect of driving the rotating disk to rotate, and due to the influence of the transmission ratio, the rotating disk can rotate slowly, so that the rotating disk can achieve the effect of diverting the external air intake.

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] refer to Figure 1-8A power supply transformer device for a high and low voltage transmission network includes a transformer body 1, a mounting shell 2 is mounted on the surface of the transformer body 1, a fan structure 3 for air intake and air outlet is bolted to both sides of the mounting shell 2, a heat dissipation mechanism 4 is bolted to the inside of the mounting shell 2, and the heat dissipation mechanism 4 is connected to the transformer body 1 on a side close to the transformer body 1; The heat dissipation mechanism 4 includes a plurality of heat dissipation pipes 41, which are evenly connected to the surface of the transformer body 1 and are connected to the transformer body 1 on the side close to the transformer body 1. The heat dissipation pipes 41 penetrate the interior of the mounting shell 2. A cold compensation component 42 is bolted to the right side of the interior of the mounting shell 2. The cold compensation component 42 is used in conjunction with the heat dissipation pipes 41. The cooling capacity compensation component 42 includes a precooling part 421, which is bolted to the front side of the inside of the mounting shell 2. A distribution part 422 is bolted to the right side of the precooling part 421. The distribution part 422 is used in conjunction with the right fan structure 3. By setting the heat dissipation pipe 41 and the cooling capacity compensation component 42, the heat dissipation pipe 41 can facilitate the circulation of transformer oil. The transformer oil rises to the oil level surface due to the high heat and enters the heat dissipation pipe 41, so that the heat taken away by the transformer oil is heat exchanged with the external air intake. At the same time, the cooling capacity compensation component 42 can compensate for the cooling capacity of the external air intake when the temperature is high in the natural environment, so that a larger temperature difference can be obtained, so that the heat of the transformer oil can be quickly exchanged with the external air intake, so that when the transformer oil circulates into the transformer main body 1, it can quickly take away the heat generated by the iron core and winding in the transformer main body 1, thereby ensuring the stable operation of the transformer main body 1.

[0031] like Figure 4 As shown, the heat dissipation pipe 41 includes two connecting pipes 411, which are respectively evenly connected to the top and bottom of the surface of the transformer body 1, and a retarder pipe 412 is connected between the opposite sides of the two connecting pipes 411. A spacer block 413 is welded inside the retarder pipe 412, and an interception net 414 is bolted to the top of the spacer block 413. The surface of the retarder pipe 412 is covered with evenly distributed heat-conducting fins 415. By setting the heat dissipation pipe 41, the transformer oil rises to the oil level surface due to high heat, and enters the connecting pipe 411 and the retarder pipe 412. The staggered spacer blocks 413 slow down the flow rate of the transformer oil in the retarder pipe 412, and prolong the flow time of the transformer oil in the outside world, thereby expanding the heat conduction effect of the heat-conducting fins 415 on the transformer oil, greatly improving the heat dissipation effect of the transformer oil, and the setting of the interception net 414 can also intercept impurities contained in the transformer oil, so as to achieve the purification effect of the transformer oil.

[0032] like Figure 4As shown, the spacer blocks 413 are evenly distributed inside the retarder tube 412 along the axis of the retarder tube 412, and the interior of the spacer blocks 413 is hollow. By arranging the spacer blocks 413 to be evenly distributed inside the retarder tube 412 along the axis of the retarder tube 412, and the interior of the spacer blocks 413 is hollow, the flow rate of the transformer oil in the outside world can be delayed and the heat dissipation effect can be improved.

[0033] like Figure 6 As shown, the precooling member 421 includes a fixed shell 4211, which is bolted to the right side of the interior of the mounting shell 2, and the two sides of the inner wall of the fixed shell 4211 are bolted with partitions 4212, and the left side of the inner wall of the fixed shell 4211 is bolted with a dehumidification plate 4213, and baffles 4214 are evenly distributed between the opposite sides of the two partitions 4212, and the interior of the baffles 4214 is bolted with a slow-release sponge 4215, and the top and bottom of the fixed shell 4211 are connected to the fluid pipeline 4216, and the partitions 4212 on both sides are respectively connected to the dehumidification plate 4213 and the distribution member 4213. 2, by setting the pre-cooling member 421, the external air entering the installation shell 2 will be distributed in the channel formed by the adjacent baffles 4214 under the action of the distribution member 422, and at the same time, the fluid pipeline 4216 is connected to the external cold water, so that the slow-release sponge 4215 absorbs and stores the cold water, so that the cold water is pre-cooled with the external air to achieve the effect of cold capacity compensation, and the moisture contained in the air is removed by the dehumidification plate 4213, so when the pre-cooled external air contacts the transformer oil, the heat exchange effect can be increased, and the heat dissipation effect of the transformer oil is improved.

[0034] like Figure 6 As shown, the baffles 4214 are stacked and equidistantly distributed between the opposite sides of the two partitions 4212, and the baffles 4214 are orifice structures. By arranging the baffles 4214 to be stacked and equidistantly distributed between the opposite sides of the two partitions 4212, and the baffles 4214 are orifice structures, it is convenient to form multiple fluid channels, and the flow rate of the external air intake can be slowed down so that the external air intake can be fully pre-cooled.

[0035] like Figure 7As shown, the distribution member 422 includes a fixed disk 4221 and a rotating disk 4222. The fixed disk 4221 is bolted to the right side of the right partition 4212. The rotating disk 4222 is bolted with a rotating shaft 4223 inside. The rotating disk 4222 is rotatably connected to the right side of the fixed disk 4221 through the rotating shaft 4223. A speed reduction portion 4224 is provided on the right side of the surface of the rotating shaft 4223. A plurality of air holes 4225 are provided inside the fixed disk 4221 and the rotating disk 4222. The two air holes 4225 on both sides are used in conjunction with each other. By setting the distribution member 422, under the traction of the fan structure 3, the external air passes through the right wind hole 4225 through the rotating disk 4222, and passes through the left wind hole 4225 through the fixed disk 4221 to enter the interior of the pre-cooling part 421. At the same time, under the action of wind force, the deceleration part 4224 can slowly drive the rotating disk 4222 to rotate, so that the air holes 4225 on both sides are connected and separated, and the external air can be evenly distributed in the interior of the pre-cooling part 421. Therefore, the external air can be fully pre-cooled in the pre-cooling part 421, thereby improving the subsequent heat exchange effect.

[0036] like Figure 6 As shown, a connecting hole 5 is provided in a ring shape on the right side of the right partition 4212 for use with the left wind hole 4225, and the connecting hole 5 corresponds one-to-one with the left wind hole 4225. By providing the connecting hole 5 and the connecting hole 5 corresponds one-to-one with the left wind hole 4225, it is convenient to form an external air intake channel, thereby facilitating the transportation of external air.

[0037] like Figure 8 As shown, the speed reduction part 4224 includes a protective shell 42241, which is sleeved on the right side of the surface of the rotating shaft 4223, and the bottom of the protective shell 42241 is bolted to the inner wall of the mounting shell 2, and the inner rotation of the protective shell 42241 is connected to the connecting shaft 42242, and the right side of the connecting shaft 42242 extends to the outside of the protective shell 42241, and the surface of the connecting shaft 42242 is annularly bolted with a fan blade 42243, and the surfaces of the connecting shaft 42242 and the rotating shaft 4223 are sleeved with a gear 42244, and the two gears 42244 are meshed with each other. By setting the speed reduction part 4224, the fan blade 42243 can be pushed to rotate under the action of wind, so that the connecting shaft 42242 synchronously drives its surface gear 42244 to rotate, and under the meshing connection of the two gears 42244, the top gear 42244 drives the rotating shaft 4223 to rotate, thereby achieving the effect of driving the rotating disk 4222 to rotate, and due to the influence of the transmission ratio, the rotating disk 4222 can rotate slowly, so that the rotating disk 4222 can achieve the effect of diverting the external air intake.

[0038] like Figure 6As shown, a fluid channel is formed between the opposite sides of the upper and lower baffles 4214, and the interiors of the left partition 4212 and the dehumidification plate 4213 are both porous structures, and the dehumidification plate 4213 is made of silica gel material. By setting a fluid channel between the opposite sides of the upper and lower baffles 4214, and the interiors of the left partition 4212 and the dehumidification plate 4213 are both porous structures, the circulation of air can be facilitated, and by setting the dehumidification plate 4213 to be made of silica gel material, the effect of dehumidifying the air can be achieved.

[0039] like Figure 7 As shown, a sealing ring 6 is bolted on the left side of the rotating disk 4222, and an annular sealing groove 7 for use with the sealing ring 6 is opened on the right side of the fixed disk 4221. The surface of the sealing ring 6 is in rotational contact with the inner wall of the annular sealing groove 7. By providing the sealing ring 6 and the annular sealing groove 7, the connection between the rotating disk 4222 and the fixed disk 4221 can be sealed, thereby reducing the loss of external air intake.

[0040] A brief description of the use process: the right-side fan structure 3 works to let the outside air pass through the filtering structure and enter the interior of the mounting shell 2, and part of the incoming air passes through the air holes 4225 and the connecting hole 5 into the channel formed by the baffle 4214, and at the same time, the fan blades 42243 are driven to rotate under the action of wind force, so that the connecting shaft 42242 drives the surface gear 42244 to rotate, and under the meshing connection of the two gears 42244, the top gear 42244 drives the rotating shaft 4223 to rotate, and then drives the rotating disk 4222 to rotate, so that the air holes 4225 on both sides are connected to different air holes 4225, so as to divert the outside air, and the outside air entering the fixed shell 4211 can, under the action of the slow-release sponge 4215, dissipate the cold water dissipated by the outside. The external air intake is precooled so that the precooled external air intake will pass through the baffle plate 4214 and the dehumidification plate 4213 into the interior of the installation shell 2, and the transformer oil rises to the oil level surface due to the high heat, and enters the connecting pipe 411 and the retarder 412. The staggered spacer blocks 413 slow down the flow rate of the transformer oil in the retarder 412, extending the flow time of the transformer oil in the outside world. At the same time, under the action of the heat-conducting fins 415, the heat of the transformer oil is heat-exchanged with the external air intake after precooling, so that the transformer oil is cooled and returns to the transformer body 1 through the bottom connecting pipe 411 for circulation to dissipate heat of the transformer body 1, and the external air intake after heat exchange will be discharged from the interior of the installation shell 2 under the action of the left fan structure 3.
