Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer installation technology, specifically to a support component and a dry-type transformer using the same. Background Technology

[0002] Transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery, and other applications. Simply put, a dry-type transformer is one whose core and windings are not immersed in insulating oil. A dry-type transformer typically includes a core made of stacked silicon steel sheets, which forms the magnetic circuit. Low-voltage and high-voltage windings are usually located on the outside of the core, and a support assembly is installed below the windings to support the entire transformer. For example, Chinese patent CN106158284A discloses a resin-cast coil dry-type transformer structure and its assembly method, using a support assembly consistent with existing technologies. Clamps are installed on the support channel steel, and then the windings are supported by pads. This method has several drawbacks: the dimensions between the pads and the clamps are usually fixed, only supporting one type of winding, resulting in poor practicality. Furthermore, when placed on the ground, the transformer is close to the ground, which is detrimental to moisture protection. Additionally, the entire transformer can only be moved using a hoisting mechanism, resulting in poor flexibility. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a support component and a dry-type transformer using the same.

[0004] The technical solution of this utility model is as follows:

[0005] A support assembly includes a base, and two base plates are mounted on the bottom of the base, the two ends of which extend outward toward the base and are connected to supports;

[0006] The base is equipped with two U-shaped channel steels, the opening directions of the two U-shaped channel steels are opposite and the distance between them can be adjusted.

[0007] Multiple sets of support components are arranged at intervals on two U-shaped channel steels. Each set of support components includes two mounting plates that are installed opposite each other on the two U-shaped channel steels. Two support pads are installed on each mounting plate. Multiple through holes are opened at intervals on the upper end face of the U-shaped channel steels. A first screw is connected to the bottom of the support pad. The screw passes through the mounting plate and the through holes and is connected to a nut.

[0008] In order to facilitate the adjustment of the distance between the two U-shaped channel steels to accommodate transformer windings of different sizes, the base is provided with a sliding groove along the direction perpendicular to the U-shaped channel steels, and the bottom of the two U-shaped channel steels is provided with a sliding strip that slides with the sliding groove.

[0009] The base has screw holes along the extension direction of the slide groove, and the U-shaped channel steel is fixed to the base by bolts.

[0010] The mounting plate is specifically designed such that a mounting groove is provided on one side of the mounting plate, and the upper edge of the U-shaped channel steel is inserted into the mounting groove.

[0011] To facilitate adjustment of the distance between the two support pads on the same mounting plate and to accommodate the support of transformer windings of different sizes, multiple mounting holes are provided along the length of the mounting plate for the first screw to pass through.

[0012] To facilitate the passage of the screw, the spacing between adjacent through holes is the same as the spacing between adjacent mounting holes.

[0013] To facilitate overall movement and improve installation and relocation flexibility, the base is equipped with casters at the four corners of the bottom, and a second screw is installed on the upper end of the casters. The second screw passes through the base and is threadedly connected to it.

[0014] In order to improve stability by limiting the second screw, a threaded cylinder is provided above the base, and the threaded cylinder is threadedly connected to the second screw.

[0015] To facilitate the support of the winding, the upper end of the support pad has two arc-shaped support grooves.

[0016] A dry-type transformer using the aforementioned support assembly, the transformer comprising a low-voltage winding and a high-voltage winding, which are respectively mounted on two arc-shaped support slots of a support pad, with the low-voltage winding located inside the high-voltage winding.

[0017] The beneficial effects of this utility model are as follows: This utility model is a support component. Firstly, by setting a base plate at the bottom of the base and installing supports at both ends of the base plate, the entire support component can be erected at a height far from the ground, which can effectively reduce moisture entering the transformer. Secondly, by setting two U-shaped channel steels with adjustable positions on the base, together with the adjustable mounting plate and support pads installed at the upper end, the size between the four opposing support pads of the same set of support components can be adjusted, which facilitates the support component to support transformer windings of different sizes, greatly improving practicality. Moreover, the above-mentioned adjustment distance method is convenient and quick, saving transformer installation time. Finally, by installing four moving wheels at the four corners of the base, the moving wheels can be supported on the ground through the cooperation of the second screw, which facilitates the movement of the transformer along with the base, improving the flexibility of transformer installation. Moreover, the moving wheels can be detached or retracted upwards away from the ground through the second screw, which facilitates the handling of the moving wheels after the transformer is moved to the designated location.

[0028] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0029] Example

[0030] As mentioned in the background section, existing transformers have many defects during installation. For example, existing support components such as support channel steel cannot adjust the distance according to the size of the transformer windings, and can only accommodate windings of one size, resulting in poor practicality. Furthermore, transformers need to be moved to a designated location using hoisting equipment, which is difficult to move on the ground. Short-distance installation and position adjustment are also quite troublesome. Therefore, the inventors have made improvements to the existing technology and designed a new type of support component, which will be described in detail below with reference to the illustrations.

[0031] This embodiment provides a support component, combined with Figure 1 and Figure 2The system includes a base 1, which is rectangular and has two base plates 2 installed at the bottom. The two ends of the base plates 2 extend outward toward the base 1 and are connected to supports 3. The lengths of the extensions at both ends are the same. The supports 3 are installed vertically downward, which can support the entire base 1 away from the ground. The bottom of the supports 3 is disc-shaped and the ground is provided with anti-slip texture to improve the overall stability.

[0032] In this embodiment, two U-shaped channel steels 4 are installed on the base 1. The opening directions of the two U-shaped channel steels 4 are opposite and the distance between them can be adjusted. That is, the two U-shaped channel steels 4 are arranged with their flat ends facing each other, their openings facing the outside of the base 1, and their length direction is consistent with the length direction of the base 1. One of the prerequisites for adapting to different windings is that the distance between the two U-shaped channel steels 4 can be adjusted. In this solution, a sliding groove 7 is opened on the base 1 along the direction perpendicular to the U-shaped channel steels 4. Two sliding grooves 7 are symmetrically opened with respect to the center line of the base 1. The bottom of the two U-shaped channel steels 4 is provided with a sliding strip 8 that slides with the sliding groove 7. By sliding the U-shaped channel steels 4 with the sliding strip 8 in the sliding groove 7, the distance between them can be adjusted. Furthermore, a screw hole 9 is opened on the base 1 along the extension direction of the sliding groove 7. The U-shaped channel steels 4 are fixed to the base 1 by bolts cooperating with different screw holes 9. The fixing method is convenient and quick.

[0033] Secondly, multiple sets of support members 5 are arranged at intervals on the two U-shaped channel steels 4, combined with Figure 5 In this scheme, three sets of support members 5 are provided. Each set of support members 5 includes two mounting plates 51 that are installed opposite to each other on two U-shaped channel steels 4. The mounting plates 51 can slide along the length direction of the U-shaped channel steel 4. The two opposite mounting plates 51 are adjusted synchronously and always maintain an opposite state. The mounting plate 51 has a mounting groove 55 on one side. The upper edge of the U-shaped channel steel 4 is inserted into the mounting groove 55. By setting the mounting groove 55, it can be connected to the upper edge of the U-shaped channel steel 4 and can slide along the edge of the U-shaped channel steel 4.

[0034] Based on the above structure, two support pads 52 are installed on each mounting plate 51, and four support pads 52 are arranged opposite each other on the two mounting plates 51. The four support pads 52 always maintain a two-to-two opposite state during adjustment. Multiple through holes 6 are opened at intervals on the upper end face of the U-shaped channel steel 4, and a first screw 53 is connected to the bottom of the support pad 52. The first screw 53 passes through the mounting plate 51 and the through hole 6 to connect the nut 54. Multiple mounting holes 56 are opened along the length of the mounting plate 51 for the first screw 53 to pass through. The first screw 53 at the bottom can pass through the through hole 6 and the mounting hole 56 to connect the nut 54, fixing the first screw 53 to the bottom of the mounting plate 51. By sliding the mounting plate 51 along the U-shaped channel steel 4, the distance between the support pads 52 on adjacent mounting plates 51 can be adjusted. Furthermore, by adjusting the distance between the two support pads 52 on the same mounting plate 51, the first screw 53 can be installed with different through holes 6 and mounting holes 56, realizing the adjustment of the distance inside the support pads 52 and between adjacent pads, thus achieving support for windings of different sizes.

[0035] It should be noted that the spacing between adjacent through holes 6 is consistent with the spacing between adjacent mounting holes 56, which facilitates the alignment of through holes 6 and mounting holes 56 during adjustment. This allows for the use of additional locking bolts to secure the mounting plate 51 through the through holes 6 and mounting holes 56 when the plate is not stable enough.

[0036] Moreover, combined Figure 1 and Figure 6 In order to support the high voltage winding 15 and the low voltage winding 14 respectively, two arc-shaped support grooves 13 are provided at the upper end of the support pad 52, which are used to support the high voltage winding 14 and the low voltage winding 14 respectively.

[0037] Based on the above structure, movable wheels 10 are installed at the bottom of the four corners of the base 1, and a second screw 11 is installed on the upper end of the movable wheels 10. A plate is provided at the bottom end of the second screw 11, which is bolted to the support seat of the movable wheel 10. The second screw 11 passes through the base 1 and is threaded to it. A threaded cylinder 12 is provided on the top of the base 1, and the threaded cylinder 12 is threaded to the second screw 11. By setting the movable wheels 10 and cooperating with the second screw 11, when the overall support assembly needs to be moved, the second screw 11 can be adjusted to drive the movable wheels 10 to support the ground, and the upper end is fixed to the upper end of the base 1 through the threaded cylinder 12. Then, the entire support assembly can be pushed to move. After moving to the designated location, the second screw 11 can be rotated to move upwards until it leaves the ground, and the movable wheels 10 can be retracted under the base 1. Alternatively, the support seat of the movable wheel 10 can be separated from the plate, and the movable wheel 10 can be disassembled.

[0038] This solution provides a dry-type transformer, combined with... Figure 3 and Figure 4 Using the support components described above as the bottom support, the transformer includes a low-voltage winding 14 and a high-voltage winding 15. This solution does not modify the transformer, so other structural components will not be described in detail. The high-voltage winding 15 and the low-voltage winding 14 are respectively installed on the two arc-shaped support grooves 13 of the support pad 52, and the low-voltage winding 14 is located inside the high-voltage winding 15. The arc-shaped surfaces of the two windings can be adapted to the arc-shaped surfaces of the arc-shaped support grooves 13. When adjusting the position of the four support pads 52 in the same set of support members 5, the four support pads 52 are always arranged opposite each other, so that the shapes formed by the extension of the arc-shaped support grooves 13 at the top of the four support pads 52 can be adapted to the corresponding windings.
