Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more specifically, to an intelligent temperature-controlled transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Oil-immersed transformers use oil as the main insulation means of the transformer and rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation. The main components of the transformer are iron core, winding, oil tank, oil pillow, respirator, explosion-proof pipe (pressure relief valve), radiator, insulating sleeve, tap switch, gas relay, thermometer, oil purifier, etc.

[0004] The temperature of the transformer will change with the ambient temperature and load conditions, but the heat dissipation device of the transformer cannot be automatically controlled according to the temperature inside the transformer during heat dissipation, resulting in the heat dissipation device being in a high-load operation state for a long time to ensure the heat dissipation effect, thereby generating unnecessary energy loss. In addition, the insulating oil inside the oil-immersed transformer will gradually age and become contaminated with the increase of usage time. The aged insulating oil will produce sludge, which will be adsorbed on the inner wall of the transformer and affect the heat dissipation performance of the equipment. Manual cleaning requires the transformer to be disassembled and all the insulating oil must be discharged before cleaning can be performed, which is more troublesome.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention adopts the setting of the control component. When the heat sink cannot effectively dissipate heat, the increased air pressure in the transformer chamber pushes the first piston plate to drive the insulating partition plate to be pulled out of the control slot, so that the two conductive parts are in contact to achieve electrical conduction, and the cooling fan is started to rotate to improve the heat dissipation effect. After the air pressure in the transformer chamber is restored and the first piston plate returns to the initial position, the insulating partition plate will be reinserted into the control slot to separate the two conductive parts, release the conduction effect, and turn off the cooling fan. Therefore, the transformer can be automatically controlled according to the temperature inside, so as to avoid the cooling fan being in a high-load carrying state to ensure the heat dissipation effect, thereby saving energy loss.

[0021] 2. The present invention uses the air pressure in the transformer chamber to make the first piston plate, the rack plate and the second piston plate reciprocate by setting a cleaning component. On the one hand, it drives the scraper to scrape the sludge on the inner wall of the transformer chamber to prevent the sludge from being adsorbed on the inner wall of the transformer chamber and affecting the heat dissipation performance. On the other hand, it enables the insulating oil to circulate and accelerate the flow rate of the insulating oil, thereby further improving the heat dissipation effect. In addition, the sludge in the insulating oil during the circulation process is filtered and stored, thereby extending the service life of the insulating oil and maintaining the insulating performance of the insulating oil, thereby ensuring the safe operation of the transformer.

[0022] 3. Through the setting of the cleaning plate of the present invention, when the second piston plate moves in the direction away from the air inlet, the insulating oil in the driving chamber will push the driving block and the support rod to drive the cleaning plate to move and compress the fifth elastic member. The cleaning plate will clean the sludge adsorbed on the filter plate during the movement, thereby preventing the filter plate from being blocked by the sludge and affecting the circulation of the insulating oil.

[0023] 4. The present invention provides an air vent groove and a magnetic sealing block. When the air pressure in the transformer chamber continues to increase and cannot be discharged, the first piston plate will be pushed to move to the extreme position, so that the first piston plate will correspond to the position of the second magnetic part. The second magnetic part can pull the magnetic sealing block to release the blockage of the air vent groove through the opposite attraction of magnetic forces. At this time, the increased air pressure will be discharged to the outside of the transformer body through the air vent groove and the air vent, preventing the air pressure inside the transformer body from being too high, thereby avoiding damage to the transformer due to excessive pressure.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Since the temperature of the transformer changes with the ambient temperature and load conditions, and the heat dissipation device of the transformer cannot automatically control the temperature inside the transformer during heat dissipation, the heat dissipation device needs to be in a high-load operation state for a long time to ensure the heat dissipation effect, thereby generating unnecessary energy loss.

[0037] refer to Figure 1-Figure 3An intelligent temperature-controlled transformer according to an embodiment of the present invention comprises a transformer body 1. The interior of the transformer body 1 is divided from top to bottom into a transformer chamber 12 and a drive chamber 13 by a partition plate 11. A winding 14 is arranged in the transformer chamber 12. Insulating oil is arranged in the transformer chamber 12.

[0038] refer to Figure 1 It also includes a heat dissipation component 2, which is arranged on the outside of the transformer body 1 and is used to dissipate heat for the transformer body 1. It includes a heat sink 21 fixedly connected to the outer wall of the transformer body 1. The heat sink 21 is arranged in multiple groups. A heat dissipation fan 22 is installed on each group of heat sinks 21. When the two conductive members 33 are in contact, electrical conduction can be achieved and the heat dissipation fan 22 can be started to rotate.

[0039] When the transformer is working normally, the heat is transferred to the inner wall of the transformer body 1 by the convection of the insulating oil. The heat of the inner wall of the transformer chamber 12 is transferred to the multiple groups of heat sinks 21. The multiple groups of heat sinks 21 dissipate the heat by natural convection of the air, thereby achieving a cooling effect.

[0040] The wind blown by the heat dissipation fan 22 speeds up the air flow rate, which can increase the heat dissipation capacity of the heat sink 21, thereby further improving the heat dissipation effect.

[0041] refer to Figure 1-Figure 6 , also includes a control component 3, which is arranged in the drive chamber 13, including a first piston plate 31, an insulating partition plate 32 and a conductive member 33, which is used to detect the temperature change in the transformer chamber 12 and control the heat dissipation component 2 to dissipate heat. A pressure relief port 34 connected to the transformer chamber 12 is opened on the top of the transformer body 1, and an air inlet 35 connected to the drive chamber 13 is opened on one side of the transformer body 1. The pressure relief port 34 and the air inlet 35 are connected through a pressure relief pipe 36. The first piston plate 31 is sealingly and slidably connected in the drive chamber 13, and the insulating partition plate 32 is fixedly connected to the side of the first piston plate 31 close to the air inlet 35. A control slide 37 connected to the drive chamber 13 is opened inside the transformer body 1. The conductive member 33 is set to two and symmetrically slidably connected in the control slide 37. A fourth elastic member 38 is connected between the ends of the two conductive members 33 away from each other and the inner wall of the control slide 37. When the insulating partition plate 32 is inserted into the control slide 37, the two conductive members 33 can be pushed apart.

[0042] During actual use, when the heat sink 21 cannot effectively dissipate heat, the temperature inside the transformer body 1 will continue to rise. When the temperature inside the transformer chamber 12 rises, the insulating oil will expand due to the heat. The expanded insulating oil will increase the air pressure in the transformer chamber 12. The increased air pressure will enter the drive chamber 13 through the pressure relief port 34, the pressure relief pipe 36 and the air inlet 35, thereby pushing the first piston plate 31 to move away from the air inlet 35. During the movement, the first piston plate 31 will drive the insulating partition plate 32 to be pulled out of the control slide groove 37. At this time, the two conductive parts 33 are in contact under the rebound action of the corresponding fourth elastic part 38 to achieve electrical conduction, and the cooling fan 22 is started to rotate to improve the heat dissipation effect.

[0043] When the air pressure in the transformer chamber 12 is restored and the first piston plate 31 returns to the initial position, the insulating partition plate 32 is reinserted into the control slot 37 to separate the two conductive members 33 , thereby releasing the conduction effect and turning off the cooling fan 22 .

[0044] To sum up, through the setting of the control component 3, when the heat sink 21 cannot effectively dissipate heat, the increased air pressure in the transformer chamber 12 pushes the first piston plate 31 to drive the insulating partition plate 32 to be pulled out of the control slot 37, so that the two conductive parts 33 are in contact to achieve electrical conduction, and the cooling fan 22 is started to rotate to improve the heat dissipation effect. After the air pressure in the transformer chamber 12 is restored and the first piston plate 31 returns to the initial position, the insulating partition plate 32 will be reinserted into the control slot 37, so that the two conductive parts 33 are separated, the conduction effect is released, and the cooling fan 22 is turned off, so that it can be automatically controlled according to the temperature inside the transformer, avoiding the cooling fan 22 from being in a high-load carrying state all the time to ensure the heat dissipation effect, thereby saving energy loss.

[0045] During actual use, the insulating oil inside the oil-immersed transformer will gradually age and become contaminated as the use time increases. The aged insulating oil will produce sludge, which will be adsorbed on the inner wall of the transformer and affect the heat dissipation performance of the equipment. Manual cleaning requires disassembling the transformer and draining all the insulating oil before cleaning, which is more troublesome. Therefore, this embodiment improves the device described in the above embodiment.

[0046] As another embodiment of the present invention, refer to Figure 1-Figure 10, and also includes a cleaning component 4, which is arranged in the transformer chamber 12, including a reciprocating threaded rod 41 and a scraper 46, which is used to cooperate with the control component 3 to clean the inner wall of the transformer chamber 12. The reciprocating threaded rod 41 is rotatably connected to the inside of the transformer chamber 12. One end of the reciprocating threaded rod 41 passes through the dividing plate 11 and extends into the driving chamber 13, and is rotatably connected to a gear 42. A rack plate 43 meshing with the gear 42 is fixedly connected to the side of the first piston plate 31 away from the air inlet 35. The outer wall of the reciprocating threaded rod 41 is threadedly connected to a threaded sleeve 44. A scraper 46 is fixedly connected to the outer wall of the threaded sleeve 44 through a plurality of support plates 45. The scraper 46 is slidably connected to the transformer chamber 12 and fits the inner wall of the transformer chamber 12. An inner ratchet 47 is provided on the inner side of the gear 42. An installation groove 48 corresponding to the position of the gear 42 is provided on the outer wall of the rotating shaft of the reciprocating threaded rod 41. A ratchet 49 capable of cooperating with the inner ratchet 47 is hinged inside the installation groove 48. A first elastic member 434 is connected between the bottom of the installation groove 48 and the ratchet 49.

[0047] The first piston plate 31 will synchronously drive the rack plate 43 to move during the movement. When the first piston plate 31 moves in the direction away from the air inlet 35, the gear 42 will be driven to rotate through the rack plate 43. When the gear 42 rotates, it can drive the reciprocating threaded rod 41 to rotate through the limiting effect of the pawl 49. During the rotation of the reciprocating threaded rod 41, the scraper 46 will be driven to slide up and down inside the transformer chamber 12 through the threaded sleeve 44 and the support plate 45, and the sludge on the inner wall of the transformer chamber 12 will be scraped off to prevent the sludge from being adsorbed on the inner wall of the transformer chamber 12 and affecting the heat dissipation performance.

[0048] When the first piston plate 31 moves toward the direction close to the air inlet 35, the gear 42 will be driven to rotate through the rack plate 43. At this time, the internal ratchet 47 on the gear 42 will squeeze the pawl 49 into the mounting groove 48 and compress the first elastic member 434. Therefore, when the first piston plate 31 moves toward the direction close to the air inlet 35, the gear 42 will not drive the reciprocating threaded rod 41 to reverse.

[0049] refer to Figure 2-Figure 5The second piston plate 410 is sealingly and slidably connected in the driving chamber 13, and is fixedly connected to the end of the rack plate 43 away from the first piston plate 31. A plurality of second elastic members 411 are connected between the side of the second piston plate 410 away from the first piston plate 31 and the inner wall of the driving chamber 13. A mud storage box 412 is fixedly connected to the side of the transformer body 1 away from the air inlet 35. An oil inlet 413 arranged in a through shape is provided on the dividing plate 11. An oil outlet 414 connected to the mud storage box 412 is provided inside the driving chamber 13. A first one-way valve 415 is provided in the oil inlet 413, and a second one-way valve 416 is provided in the oil outlet 414. The insulating oil in the transformer chamber 12 will enter the driving chamber 13 through the oil inlet 413 and the first one-way valve 415.

[0050] During the movement, the first piston plate 31 will synchronously drive the second piston plate 410 to move through the rack plate 43. When the second piston plate 410 moves in a direction away from the air inlet 35, it will compress the second elastic member 411 and push the insulating oil in the drive chamber 13 into the mud storage box 412 through the oil outlet 414 and the second one-way valve 416.

[0051] When the second elastic member 411 pushes the second piston plate 410 back to move toward the air inlet 35 , the insulating oil in the transformer chamber 12 is drawn into the drive chamber 13 through the oil inlet 413 and the first one-way valve 415 .

[0052] refer to Figure 3 and Figure 4 The mud storage box 412 is sealed and slidably connected with a mud storage plate 417 inside, and a third elastic member 418 is connected between the bottom of the mud storage plate 417 and the inner wall of the mud storage box 412. An oil discharge port 419 is provided on the top of the mud storage box 412, and a filter plate 420 is fixedly connected to the oil discharge port 419. An oil inlet 421 is provided on the upper side of the variable pressure chamber 12 near the mud storage box 412, and the oil discharge port 419 is connected to the oil inlet 421 through an oil discharge pipe 422. A drive chamber 13 is provided on the side near the mud storage box 412 with a filter plate 420 connected to the mud storage box 419. 2, a cleaning chute 423 is connected to the inside of the cleaning chute 423, a driving block 424 is sealed and slidably connected in the cleaning chute 423, a side of the driving block 424 close to the mud storage box 412 is fixedly connected with a plurality of support rods 425, and the other end of the plurality of support rods 425 away from the driving block 424 is fixedly connected with a cleaning plate 426 capable of cleaning the filter plate 420, a fifth elastic member 435 is connected between the side of the cleaning plate 426 away from the driving block 424 and the inner wall of the mud storage box 412, and an alarm 427 is arranged on the inner side of the bottom of the mud storage box 412.

[0053] Due to the setting of the second one-way valve 416, the insulating oil cannot flow back through the oil outlet 414 after entering the mud storage box 412, and the insulating oil entering the mud storage box 412 will return to the transformer chamber 12 through the oil drain port 419, the filter plate 420, the oil drain pipe 422 and the oil inlet 421 to achieve circulation. During the circulation of the insulating oil inside the mud storage box 412 and the oil drain pipe 422, the mud storage box 412 and the oil drain pipe 422 will come into contact with the external air, thereby cooling the insulating oil, and the flow rate of the insulating oil inside the transformer chamber 12 will be accelerated during the circulation process, thereby further improving the heat dissipation effect.

[0054] The sludge in the insulating oil will be filtered by the filter plate 420 during the circulation process, and the sludge cannot re-enter the transformer chamber 12, thereby extending the service life of the insulating oil and avoiding excessive precipitation of the sludge. By replacing the fifth elastic member 435 with a different elastic coefficient, the elastic coefficient of the fifth elastic member 435 is made smaller than the elastic coefficient of the elastic member inside the second one-way valve 416. When the second piston plate 410 moves in a direction away from the air inlet 35, the insulating oil in the driving chamber 13 will preferentially push the driving block 424 and the support rod 425 to drive the cleaning plate 426 to move and compress the fifth elastic member 435. The cleaning plate 426 will clean the sludge adsorbed on the filter plate 420 during the movement to avoid the sludge clogging the filter plate 420 and affecting the circulation of the insulating oil.

[0055] The weight of the insulating oil itself cannot push the mud storage plate 417 to compress the third elastic member 418. Since the sludge in the mud storage box 412 cannot be discharged, the sludge will be deposited on the mud storage plate 417 under the action of its own weight. As the sludge gradually accumulates, the weight of the mud storage plate 417 will gradually increase. Therefore, under the simultaneous action of the insulating oil and the sludge, the mud storage plate 417 will gradually compress the third elastic member 418 to move downward in the mud storage box 412 as the sludge accumulates. When the mud storage plate 417 compresses the third elastic member 418 to the limit position, the bottom of the mud storage plate 417 will contact the alarm 427, thereby triggering an alarm to remind the staff to clean the sludge in the mud storage box 412.

[0056] refer to Figure 5-Figure 7A vent groove 428 is provided in a through shape on one side of the first piston plate 31, a blocking groove 429 is provided inside the first piston plate 31 and penetrates the vent groove 428, a magnetic blocking block 430 is slidably connected in the blocking groove 429 for blocking the vent groove 428, a first magnetic component 431 and a second magnetic component 432 corresponding to the position of the magnetic blocking block 430 are fixedly connected to the inner wall of the driving chamber 13, the first magnetic component 431 can push the magnetic blocking block 430 to block the vent groove 428 through the repulsion of like-charged magnetic force, the second magnetic component 432 can pull the magnetic blocking block 430 to release the blockage of the vent groove 428 through the attraction of opposite-charged magnetic force, and an vent port 433 connected to the outside of the transformer body 1 is provided inside the driving chamber 13.

[0057] When the air pressure in the transformer chamber 12 continues to increase, pushing the first piston plate 31, the rack plate 43 and the second piston plate 410 to compress the second elastic member 411 and move to the extreme position in the direction away from the air inlet 35, the first piston plate 31 will correspond to the position of the second magnetic member 432, and the second magnetic member 432 can pull the magnetic blocking block 430 to release the blockage of the air vent 428 through the opposite magnetic attraction. At this time, the increased air pressure will be discharged to the outside of the transformer body 1 through the air vent 428 and the air vent 433, so as to prevent the internal air pressure of the transformer body 1 from being too high, thereby avoiding damage to the transformer due to excessive pressure.

[0058] After the air release groove 428 is opened, the second piston plate 410, the rack plate 43 and the first piston plate 31 will move towards the direction close to the air inlet 35 under the rebound effect of the second elastic member 411. When the positions of the first piston plate 31 and the first magnetic member 431 correspond, the first magnetic member 431 can push the magnetic blocking block 430 to block the air release groove 428 through the repulsion of the same magnetic force. At this time, the air pressure in the variable pressure chamber 12 can push the first piston plate 31, the rack plate 43 and the second piston plate 410 to move again, thereby realizing reciprocating motion.

[0059] By adjusting the installation position of the first magnetic part 431, the air relief groove 428 is blocked before the insulating partition plate 32 is inserted into the control slide groove 37, so as to avoid affecting the heat dissipation work of the cooling fan 22 when the air pressure has not been restored. When the air pressure in the transformer chamber 12 is restored, the first piston plate 31 can gradually return to the initial position under the rebound action of the second elastic part 411, so that the insulating partition plate 32 is inserted into the control slide groove 37, so that the two conductive parts 33 are separated, the conduction effect is released, and the cooling fan 22 is turned off.

[0060] In summary, by setting the cleaning component 4 and utilizing the air pressure in the transformer chamber 12, the first piston plate 31, the rack plate 43 and the second piston plate 410 are caused to reciprocate. On the one hand, the scraper 46 is driven to scrape off the sludge on the inner wall of the transformer chamber 12 to prevent the sludge from being adsorbed on the inner wall of the transformer chamber 12 and affecting the heat dissipation performance. On the other hand, the insulating oil is allowed to circulate and the flow rate of the insulating oil is accelerated, thereby further improving the heat dissipation effect. The sludge in the insulating oil during the circulation process is filtered and stored, thereby extending the service life of the insulating oil and maintaining the insulating performance of the insulating oil, thereby ensuring the safe operation of the transformer.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
