Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a high-efficiency heat dissipation dry-type transformer. Background Art

[0002] A dry-type transformer refers to a transformer whose core and windings are not immersed in insulating oil. During use, a dry-type transformer continuously generates a large amount of heat. If the heat is not removed in time, it will affect the normal operation and service life of the dry-type transformer. Existing cooling methods are divided into natural air cooling and forced air cooling. Among them, forced air cooling is achieved by installing cooling fans on the front and rear sides of the windings. The cooling fans directly blow on the front and rear outer walls of the windings, removing the heat from the outer walls of the windings and accelerating the air flow outside the windings, thereby achieving the purpose of heat dissipation.

[0003] However, when the cooling fans installed on the front and rear sides of the winding blow cold air to the winding, they can often only blow through the front and rear sides of the winding, and thus can only take away most of the hot air located on both sides of the outer wall of the winding. There are blind spots for blowing on the outer walls on the left and right sides of the winding, which makes it impossible for the cold air blown by the fan to fully and comprehensively contact the outer wall of the winding, and it is impossible to take away all the hot air on the outer wall of the winding, so that the winding cannot be fully and evenly dissipated, resulting in poor heat dissipation effect.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example 1

[0032] Reference Figures 1 to 4, which is a first embodiment of the present invention, includes a high-efficiency heat dissipation dry-type transformer, including a main unit 1, multiple groups of windings 4 provided on the main unit 1, torsion units 3 and limit units 2 provided at upper and lower ends of the windings 4, and multiple groups of guide units 5 distributed around the outer wall of the windings 4, the guide unit 5 including an air guide plate 1 51 spirally wound around the outer wall of the winding 4, the end of the air guide plate 1 51 being fixedly connected to the limit unit 2, and an air guide plate 2 52 inserted and retracted into the air guide plate 1 51, the top of the air guide plate 2 52 being fixedly connected to the torsion unit 3;

[0033] The outer ends of the air guide plate 1 51 and the air guide plate 2 52 are both provided with an arc structure bent toward the inner wall of the winding 4. A guide groove 53 is separated between each two adjacent groups of the multiple guide units 5, and the guide groove 53 is a spiral structure consistent with the spiral direction of the air guide plate 1 51; Figure 4 It can be seen that the inwardly curved structure of the guide unit 5 can guide the airflow flowing along the inner walls of the first air guide plate 51 and the second air guide plate 52, so that the airflow is always blown in the direction of the winding 4, thereby avoiding airflow dispersion;

[0034] Air coolers 6 are provided on both sides below the twisting unit 3 , and the air outlet direction of the air cooler 6 is aligned with the end opening of the guide groove 53 . The cold air blown out by the air cooler 6 can be guided by the guide unit 5 to flow in the guide groove 53 .

[0035] Further, refer to Figure 4 The wind guide plate 1 51 is provided with a storage groove 511 that matches the structure of the wind guide plate 2 52, and the wind guide plate 2 52 is inserted into the limiting slider 521. A stopper 512 is provided at the end opening of the storage groove 511, and limiting sliders 521 are provided on both sides of the end of the wind guide plate 2 52. The wind guide plate 1 51 can store the wind guide plate 2 52 through the storage groove 511, and conversely, the wind guide plate 2 52 can also be extended from the wind guide plate 1 51 to extend the entire length of the guide unit 5. The stopper 512 can prevent the wind guide plate 2 52 from completely separating from the wind guide plate 1 51 by cooperating with the limiting slider 521, thereby ensuring the tightness of the two. The guide unit 5 is made of a high-temperature resistant and flexible material as a whole, and can undergo a certain degree of bending and deformation.

[0036] During use, refer to Figure 4, multiple groups of guide units 5 are distributed on the outer wall of the winding 4 in coordination with each other, and each group of guide units 5 is spirally wound and fits on the outer wall of the winding 4. The guide groove 53 between each two adjacent groups of guide units 5 is restricted by the spiral posture of the two adjacent groups of guide units 5 and also forms a spiral structure. Multiple groups of guide grooves 53 are spliced with each other and can completely surround the winding 4. At this time, all parts of the outer wall of the winding 4 are within the range of the guide groove 53. At this time, the air cooler 6 blows the air flow from the bottom into the guide groove formed by each two adjacent groups of guide units 5. In the flow groove 53, the air flow is guided by the spiral structure of the guide groove 53 and flows on the outer wall of the winding 4 in a spiral ascending trajectory. The spiral guide groove 53 can ensure that the air flow passes through all parts of the winding evenly and fully, thereby achieving all-round sweeping of the outer wall of the winding and avoiding the generation of dead corners. The spiral guide groove 53 can extend the contact time of the air flow with the outer wall of the winding 4 to a certain length, allowing the cold air to fully exchange heat with the outer wall of the winding 4, thereby effectively ensuring the heat dissipation effect and significantly improving the heat dissipation efficiency of the device. Example 2

[0037] Reference Figures 1 to 8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that by adjusting the limiting unit 2 and the torsion unit 3, heat dissipation operation is achieved for dry-type transformers with windings of different specifications.

[0038] Compared with Example 1, further, referring to Figure 1 The main unit 1 includes a base 11 located below the winding 4, a horizontal bracket 12 arranged horizontally on the base 11, and the limiting unit 2 is limitedly installed on the horizontal bracket 12, a height adjustment component 13 and an auxiliary bracket 14 symmetrically arranged at both ends of the horizontal bracket 12, and a horizontal bracket 2 15 horizontally connected between the top of the height adjustment component 13 and the auxiliary bracket 14, and the torsion unit 3 is installed on the horizontal bracket 2 15.

[0039] Among them, reference Figure 1 The side surfaces of both ends of the horizontal bracket 12 are provided with a fixing ear 121, the bottom surface of the horizontal bracket 12 is vertically provided with a limiting axis 122, the bottom surface of the horizontal bracket 2 15 is provided with a limiting axis 2 151, and the torsion unit 3 is sleeved on the limiting axis 2 151, and the side surfaces of both ends of the limiting axis 2 151 are provided with a fixing ear 2 152.

[0040] Among them, reference Figure 2The height adjustment component 13 includes a sleeve 131 fixedly connected to one end of the horizontal bracket 12 in the vertical direction, a screw 132 threadedly connected to the axial position of the sleeve 131, and the screw 132 passes through the horizontal bracket 2 15 upward, and a turntable 133 fixedly connected to the top of the screw 132. The screw 132 can be rotated through the turntable 133, and the rotating screw 132 can be retracted from the sleeve 131, thereby achieving the purpose of adjusting the overall support height of the height adjustment component 13. When the height of the height adjustment component 13 changes, the horizontal bracket 2 15 and the limit unit 2 will be synchronously driven to change their height positions, thereby meeting the purpose of making corresponding adjustments following the winding height. The auxiliary bracket 14 has the same structural principle as the height adjustment component 13.

[0041] Among them, reference Figure 5 and Figure 6 The limiting unit 2 is rotatably connected to the limiting shaft 122. The limiting unit 2 includes a mounting assembly 21 sleeved on the limiting shaft 122, a plurality of limiting components 22 equally connected to the mounting assembly 21, a driving assembly 23 located on the bottom surface of the mounting assembly 21 and also sleeved on the limiting shaft 122, a gear 24 fixedly connected to the axis center position of the bottom surface of the driving assembly 23, and the limiting shaft 122 passes downward through the gear 24, and a worm 25 arranged on the side of the gear 24, and the worm 25 is fixed to the bottom surface of the driving assembly 23. 25 is in transmission engagement with gear 1 24, and at the same time, both ends of the worm 25 extend outwardly through the fixing ear 121, the mounting assembly 21 is fixedly connected to the limiting shaft 122, and the driving assembly 23 and the gear 1 24 are both rotationally limitedly connected to the limiting shaft 122, and can rotate around the limiting shaft 122 as the axis, and the worm 1 25 and the gear 1 24 can form a worm gear transmission structure, and then by rotating the worm 1 25, the gear 1 24 and the driving assembly 23 can be driven to rotate synchronously.

[0042] Among them, reference Figure 6 The mounting assembly 21 includes a limiting plate 211 sleeved on the limiting shaft 122, and a plurality of limiting grooves 212 equally divided on the limiting plate 211, and each group of limiting grooves 212 is inserted into a group of limiting components 22. The limiting plate 211 is fixedly connected to the limiting shaft 122 and cannot move, while the limiting grooves 212 limit the limiting components 22 so that the limiting components 22 can only slide and translate along the limiting grooves 212.

[0043] Among them, reference Figure 6The limiting component 22 includes a limiting rod 221 inserted into the limiting groove 212, a connecting plate 222 fixedly connected to the outer end of the limiting rod 221, and the connecting plate 222 is fixedly connected to the end of the air guide plate 51, and a plurality of groups of teeth 223 are equally arranged on the bottom surface of the limiting rod 221. The limiting component 22 is slidingly inserted into the limiting groove 212 through the limiting rod 221, and the connecting plate 222 is fixedly connected to the air guide plate 51, so as to drive the air guide plate 51 and the guide unit 5 as a whole to move along with the limiting component 22.

[0044] Among them, reference Figure 6 The driving assembly 23 includes a driving disk 231 located below the limiting disk 211, and a volute rack 232 fixedly connected to the top surface of the driving disk 231 in a volute structure, and the volute rack 232 is engaged with the teeth 223. The driving disk 231 can be rotated by the drive of the gear 1 24, and the rotating driving disk 231 can be engaged with the teeth 223 at the bottom of the limiting component 22 through the volute rack 232. Therefore, the rotating volute rack 232 can drive the limiting component 22 to telescopically slide in the limiting groove 212.

[0045] Among them, reference Figure 7 The torsion unit 3 includes a fixed disk 31 rotatably sleeved on the limiting shaft 151, a gear 32 fixedly connected to the axial position of the top end of the fixed disk 31, multiple groups of limiting rods 33 circumferentially inserted on the fixed disk 31, a connecting plate 34 fixedly connected to the end of the limiting rod 33, and the top of the air guide plate 52 is fixedly connected to the connecting plate 34, and a worm 35 arranged on one side of the gear 32, and the worm 35 is engaged with the gear 32, and at the same time, the two ends of the worm 35 extend outward into the fixed ear 152. The fixed disk 31 can be driven by the gear 32 to rotate with the limiting shaft 151 as the axis, and the limiting rod 33 is connected to the air guide plate 52 through the connecting plate 34, and can follow the limiting component 22 to move outward to perform a telescopic action.

[0046] Further, refer to Figure 2 The worm gear 2 35 and the worm gear 1 25 are respectively connected to the cross bracket 12 and the cross bracket 2 15, and knobs are provided at the ends of both. By rotating the worm gear 2 35 and the worm gear 1 25, the torsion unit 3 and the limit unit 2 can be driven to perform adjustment actions respectively.

[0047] During use, combine Figure 8, according to the actual size of the winding 4, the worm 25 is rotated to drive the driving assembly 23 to rotate as a whole with the limiting shaft 122 as the axis. The rotating driving assembly 23 can push the limiting component 22 to slide along the limiting groove 212 through the engagement of the worm rack 232 with the teeth 223. The four groups of limiting components 22 move synchronously, which can form an expansion or contraction action with the winding 4 as the axis. The moving limiting component 22 can drive the guide unit 5 to move synchronously, so that the position of the guide unit 5 can always be maintained near the outer wall of the winding 4, thereby achieving the purpose of adjusting the installation range of the guide unit 5 according to the diameter of the winding 4; the distance between the cross bracket 2 15 and the cross bracket 1 12 is adjusted by the height adjustment component 13. During the movement of the cross bracket 2 15, the cross bracket 2 15 will pass through the torsion unit 3 The connecting plate 2 34 pulls the air guide plate 2 52 so that the air guide plate 2 52 extends from the air guide plate 1 51, thereby ensuring that the overall length of the guide unit 5 matches the height of the winding 4, so that the guide unit 5 is always in contact with the winding 4. The spiral amplitude of the guide unit 5 with the lengthened length will also change. The worm gear 2 35 can be used to drive the gear 2 32 to rotate the fixed disk 31. The rotation causes the fixed disk 31 to drive the air guide plate 2 52 to undergo torsional deformation through the limiting rod 2 33 and the connecting plate 2 34, forming a new spiral amplitude, thereby realizing the adjustment of the spiral amplitude to meet more usage requirements. The surrounding width, height and spiral angle of the guide unit 5 can be adjusted by the limiting unit 2, the torsion unit 3 and the height adjustment component 13, so that the device can be applied to dry-type transformers with windings of different sizes.

[0048] The remaining structures are the same as those of Example 1.
