Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a heat dissipation transformer and a temperature control method. Background Technology

[0002] A transformer is a device used in power transmission to ensure the stable operation of the power grid by changing the alternating current voltage. During operation, the internal coils of a transformer generate a significant amount of heat. To maintain normal operation, air cooling is typically used to dissipate heat. To prevent dust or fine particles from entering the transformer, filters are usually used to remove them.

[0003] For example, Chinese Patent CN117877844B discloses a ventilation and dustproof transformer device. This device includes a transformer body, an air guide hood, a dust removal mechanism, and an air supply mechanism. The air guide hood is connected to the transformer body. The dust removal mechanism includes a dust collector housing, scrapers, drive shafts, a filter belt, and a drive component. The dust collector housing is installed inside the air guide hood, and the scrapers are installed on the air guide hood. There are two drive shafts, rotatably connected to the dust collector housing. The filter belt is fitted over each drive shaft and contacts the scrapers. The drive component drives any one of the drive shafts to rotate. The air supply mechanism is installed inside the air guide hood and located between the dust removal mechanism and the air outlet. By using a dust removal mechanism installed inside the air guide hood to filter the intake air, and using scrapers to remove dust and fine particles from the filter belt, dust accumulation is prevented, thus avoiding dust buildup and maintaining heat dissipation. Under the action of the air supply mechanism, the air can only enter from one end of the air guide shroud. However, the external air direction is constantly changing. When the position of the air guide shroud deviates from the direction of external air flow, the heat dissipation effect is poor. Moreover, the external air needs to pass through two layers of filter belts before entering the transformer body, which affects the air intake efficiency. Summary of the Invention

The first exhaust fan 52 is used to correspond to the first through hole 11. Optionally, the first wind pressure sensor 51 is housed in the first air intake chamber 312. When exhaust is discharged from the first shroud 31, the first exhaust fan 52 slides to the position corresponding to the first through hole 11 and then exhausts air into the first shroud 31. As the pressure inside the first shroud 31 increases, it forces the first air intake valve 33 to compress the first elastic element until the first air intake valve 33 abuts against the first protrusion 36 and closes the first air intake hole 321. As the first exhaust fan 52 continues to exhaust air, it further forces the first air outlet valve 34 to compress the first spring and open the first air outlet 322, thereby allowing the air inside the chassis 10 to be discharged into the first air outlet chamber 313, and then discharged through the first filter belt 41 and the first air vent 311.

[0035] In one embodiment, the first heat dissipation component 50 further includes a first air intake fan 53 slidably disposed at one end of the chassis 10. The first air intake fan 53 is used to correspond to the first through hole 11. When air is intake from the first fan cover 31, the first air intake fan 53 slides to the position corresponding to the first through hole 11 and then blows air toward the chassis 10 to accelerate the entry of external air into the chassis 10 through the first air intake hole 321. The first heat dissipation assembly 50 further includes a first sliding plate 54, a first lifting plate 55, a first lifting power element (not shown), a first guide rail (not shown), a first telescopic power element 56, and a first slide rail 57.

[0037] like Figure 4 and Figure 6As shown, the second air guide assembly 60 includes a second air hood 61, a second support plate 62, a second air inlet valve 63, and a second air outlet valve 64.

In one embodiment, the second dustproof assembly 70 further includes a second conveying roller (not shown), a second pressure roller (not shown), a second roller (not shown), a second guide roller (not shown), a second tension roller (not shown), and a second feeding roller (not shown), which are sequentially rotatably connected to the second air shroud 61. The second dustproof assembly 70 also includes a third telescopic block (not shown), a third column (not shown), a third telescopic spring (not shown), a fourth telescopic block (not shown), a fourth column (not shown), and a fourth telescopic spring (not shown). The second dustproof assembly 70 also includes a second rotational power element (not shown), a driving wheel (not shown), a synchronous belt (not shown), and multiple driven wheels (not shown). In one embodiment, the structure of the second dustproof assembly 70 is similar to that of the first dustproof assembly 40, and will not be described in detail below.

[0039] like Figure 4 and Figure 6 As shown, the second heat dissipation assembly 80 includes a second wind pressure sensor 81 and a second exhaust fan 82. The second wind pressure sensor 81 is installed inside the second shroud 61, and the second exhaust fan 82 is slidably disposed at one end of the chassis 10, corresponding to the second through hole 12. Optionally, the second wind pressure sensor 81 is housed in the second air intake chamber 612; furthermore, the position of the second wind pressure sensor 81 in the second air intake chamber 612 is the same as the position of the first wind pressure sensor 51 in the first air intake chamber 312 to ensure measurement accuracy. In one embodiment, the second heat dissipation assembly 80 further includes a second air intake fan 83 slidably disposed at one end of the chassis 10, corresponding to the second through hole 12.

[0040] In one embodiment, the second heat dissipation assembly 80 further includes a second sliding plate (not shown), a second lifting plate (not shown), a second lifting power element (not shown), a second guide rail (not shown), a second telescopic power element (not shown), and a second slide rail (not shown); the second heat dissipation assembly 80 also includes a second sealing seat (not shown) installed at one end of the chassis 10, the second sealing seat being disposed corresponding to the second through hole 12; the second sealing seat is used to seal the second sliding plate or the second lifting plate; in one embodiment, the structure of the second heat dissipation assembly 80 is similar to that of the first heat dissipation assembly 50, and will not be described in detail below.

[0041] The heat dissipation transformer 100 also includes a control system (not shown in the figure). The control system includes a controller, a thermometer, and a timer. The thermometer is installed inside the chassis 10 to detect the temperature inside the chassis 10. The thermometer, timer, first exhaust fan 52, second exhaust fan 82, first intake fan 53, and second intake fan 83 are all connected to the controller to realize automatic control.

[0042] When the temperature inside the chassis 10 is lower than a preset value, it is in a normal ventilation state. The first intake valve 33 opens the first intake port 321, and the first exhaust valve 34 closes the first exhaust port 322. The first intake fan 53 and the first exhaust fan 52 are both moved away from the first through hole 11. The second intake valve 63 opens the second intake port 621, and the second exhaust valve 64 closes the second exhaust port 622. The second intake fan 83 and the second exhaust fan 82 are both moved away from the second through hole 12 to facilitate air circulation and heat dissipation of the transformer body 20. In addition, according to the preset dust removal time, the first filter belt 41 moves in one direction first, and the dust on the first filter belt 41 is scraped off by the action of the first scraper 42 or the second scraper 43. When the next dust removal time is reached, the first filter belt 41 moves in the opposite direction to achieve reciprocating movement. By periodically scraping off the dust on the first filter belt 41, dust blockage is prevented. The second filter belt 71 is operated in the same way.

[0043] When the temperature value fed back by the thermometer is greater than the preset temperature value, the airflow direction is determined based on the pressure values ​​fed back by the first air pressure sensor 51 and the second air pressure sensor 81, thereby controlling the operation of the first exhaust fan 52, the first intake fan 53, the second exhaust fan 82, and the second intake fan 83. For example, when the pressure values ​​fed back by the first air pressure sensor 51 and the second air pressure sensor 81 are the same, or when the pressure value fed back by the first air pressure sensor 51 is greater than the pressure value fed back by the second air pressure sensor 81, the first hood 31 takes in air and the second hood 61 takes out air, until the temperature value fed back by the thermometer is less than the preset temperature value, and normal ventilation is restored; specifically, the first intake fan 53 slides to the position of the first through hole 11, and the second exhaust fan 82 slides to the position of the second through hole 12. At this time, under the action of the first intake fan 53, external air flows sequentially through the first air outlet 311, the first air intake chamber 312, the first air intake hole 321, and the first through hole 11. The airflow enters the chassis 10. Under the action of the second exhaust fan 82, the high-temperature airflow forces the second intake valve 63 to close the second intake hole 621, which in turn pushes the second exhaust valve 64 to open the second exhaust hole 622. The high-temperature airflow flows through the second through hole 12, the second exhaust hole 622, the second exhaust chamber 613 and the second air outlet 611 in sequence and is discharged. The discharged airflow blows back onto the second filter belt 71, blowing away some of the dust on the second filter belt 71 and the fourth scraper 73. Through the cooperation of the first intake fan 53 and the second exhaust fan 82, the airflow is accelerated, so that the airflow direction through the transformer body 20 is consistent with the external wind direction, reducing energy consumption and improving heat dissipation.

[0044] When the pressure value fed back by the first wind pressure sensor 51 is less than the pressure value fed back by the second wind pressure sensor 81, the second hood 61 takes in air and the first hood 31 takes out air until the temperature value fed back by the thermometer is less than the preset temperature value, and the normal ventilation state is restored. Specifically, the second intake fan 83 slides to the position of the second through hole 12 and the first exhaust fan 52 slides to the position of the first through hole 11. At this time, under the action of the second intake fan 83, the external air flows through the second air outlet 611, the second air inlet 612, the second air inlet 621 and the second through hole 12 in sequence into the chassis 10. Moreover, under the action of the first exhaust fan 52, the high temperature airflow flows through the first through hole 11, the first air outlet 322, the first air outlet 313 and the first air outlet 311 in sequence, and the exhaust airflow back-blowing the first filter belt 41 blows away some of the dust on the first filter belt 41 and the second scraper 43.

[0045] The heat dissipation transformer 100 of the present invention determines the wind direction by using the first wind pressure sensor 51 and the second wind pressure sensor 81, and then controls the first exhaust fan 52 or the second exhaust fan 82 to work, thereby adjusting the air intake direction of the chassis 10 according to the external wind direction; by using the reciprocating sliding arrangement of the first filter belt 41 and the second filter belt 71, a single-layer closed air outlet is achieved, reducing wind resistance and improving heat dissipation effect.

[0046] A temperature control method for a heat dissipation transformer, based on the aforementioned heat dissipation transformer, comprises the following steps: Dust Removal: The dust removal time is set to T, the length of the first air outlet 311 is L1, and the length of the second air outlet 611 is L2. When the first dust removal time is reached, both the first filter belt 41 and the second filter belt 71 move downwards. At this time, the part of the first filter belt 41 corresponding to the first air inlet 312 is clean, and the part of the second filter belt 71 corresponding to the second air inlet 612 is clean, preventing dust from clogging the filter belts. Optionally, the first filter belt 41 moves downwards by L1 / 2, and the second filter belt 71 moves downwards by L2 / 2. The part of the first filter belt 41 corresponding to the first air outlet 313 is dusty, and the part of the second filter belt 71 corresponding to the second air outlet 613 is dusty, but this does not affect the air intake. Therefore, the movement distance and time of the filter belts can be reduced. Further, T is 24h. When the next dust removal time arrives, the first filter belt 41 and the second filter belt 71 move in opposite directions again; in one embodiment, the first filter belt 41 moves in opposite directions by L1, and the second filter belt 71 moves in opposite directions by L2. At this time, the parts of the first filter belt 41 corresponding to the first air inlet chamber 312 and the first air outlet chamber 313 are in a clean state; the second filter belt 71 is the same.

[0047] Normal ventilation: When the temperature inside the chassis 10 is lower than the preset value, the first intake valve 33 opens the first intake port 321, the first exhaust valve 34 closes the first exhaust port 322, and the first intake fan 53 and the first exhaust fan 52 are both moved away from the first through hole 11; the second intake valve 63 opens the second intake port 621, the second exhaust valve 64 closes the second exhaust port 622, and the second intake fan 83 and the second exhaust fan 82 are both moved away from the second through hole 12 to facilitate air circulation; Determine wind direction: When the temperature value fed back by the thermometer is greater than the preset temperature value, that is, when the temperature inside the chassis 10 is greater than the preset value, the wind direction is determined based on the wind pressure values ​​fed back by the first wind pressure sensor 51 and the second wind pressure sensor 81. Exhaust control: If the wind pressure value fed back by the first wind pressure sensor 51 is the same as the wind pressure value fed back by the second wind pressure sensor 81, or if the wind pressure value fed back by the first wind pressure sensor 51 is greater than the wind pressure value fed back by the second wind pressure sensor 81, then the first shroud 31 takes in air and the second shroud 61 takes out air; that is, after the second exhaust fan 82 slides to the second through hole 12, as the second exhaust fan 82 continues to blow air onto the second shroud 61, it forces the second intake valve 63 to close the second intake hole 621, thereby forcing the second exhaust valve 64 to open the second exhaust hole 622; furthermore, the first intake fan 53 slides to the position of the first through hole 11 and the second exhaust fan 82 slides to the position of the second through hole 12. If the wind pressure value fed back by the first wind pressure sensor 51 is less than the wind pressure value fed back by the second wind pressure sensor 81, then the second shroud 61 takes in air and the first shroud 31 takes out air; that is, the first exhaust fan 52 slides to the first through hole 11, and as the first exhaust fan 52 continues to blow air onto the first shroud 31, it forces the first intake valve 33 to close the first intake hole 321, thereby forcing the first exhaust valve 34 to open the first exhaust hole 322; until the temperature value fed back by the thermometer is less than the preset temperature value, that is, when the temperature inside the chassis 10 is less than the preset value, then the normal ventilation state is restored.

[0048] In one embodiment, when the controlled exhaust step is initiated, if the time since the last dust removal is less than T / 6, neither the first filter belt 41 nor the second filter belt 71 will move, because the time since the last dust removal is short and not much dust has accumulated on the filter belts. If the time since the last dust removal is greater than T / 6, both the first filter belt 41 and the second filter belt 71 need to slide to prevent dust from clogging the filter belts. Specifically, if the first filter belt 41 moved downward by L1 / 2 during the last dust removal time, it will continue to move downward by L1 / 2. When the next dust removal time is reached, the first filter belt 41 will move in the opposite direction by L1. If the first filter belt 41 moved upward by L1 during the last dust removal time, it will move downward by L1 / 2. When the next dust removal time is reached, the first filter belt 41 will continue to move downward by L1 / 2, and the second filter belt 71 will move downward in the same way.

[0049] When the controlled exhaust is completed and the time until the next dust removal time is less than T / 8, the first filter belt 41 and the second filter belt 71 will not move when the next dust removal time arrives. At this time, there will be less dust on the first filter belt 41 and the second filter belt 71.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
