Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, specifically to a dry-type transformer that is easy to install. Background Technology

[0002] Dry-type transformers are transformers whose core and windings are not immersed in insulating oil. They are characterized by low loss, low noise, and no pollution, and are often used in buildings, airports, docks and other places.

[0003] In dry-type transformers, the transformer structure, including the coils, is typically fixed to a base. Below the base are two parallel channel steels used for starting support, installation, and for forklift movement. Dry-type transformers are usually installed by securing the channel steels to the mounting surface with multiple bolts. However, different transformer models have different dimensions, resulting in variations in the position of the mounting holes. This can lead to incompatibility with existing mounting holes on the surface, requiring the drilling of new holes or the customization of matching mounting fixtures. This makes transformer installation inconvenient and inflexible, and increases costs. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a dry-type transformer that is easy to install.

[0005] The technical solution of this utility model is as follows:

[0006] A dry-type transformer that is easy to install includes a base and a transformer body fixed on the base. Two supporting channel steels arranged in parallel left and right are fixed at the bottom of the base. Sliding grooves are provided on the front and rear surfaces of the base. The bottom of the base is also provided with a mounting component, which includes a connecting plate and a mounting plate. The upper edge of the connecting plate is provided with two sliding parts, which respectively cooperate with the two sliding grooves. The connecting plate is configured to slide horizontally and rotate vertically through the two sliding parts. The mounting plate is connected to the lower edge of the connecting plate and is provided with mounting holes.

[0007] The cross-section of the sliding part is elliptical or cam-shaped, and the maximum profile dimension of the cross-section is greater than the vertical width of the groove.

[0008] To ensure the mounting components can more stably secure the base, toothed grooves are provided on the lower and / or upper sides of the slide, arranged densely on both sides.

[0009] Furthermore, a friction-enhancing block is provided between the sliding part and the tooth groove, which slides synchronously with the sliding part. The friction-enhancing block has teeth on the side facing the tooth groove that can match the tooth groove, increasing the friction between the mounting part and the sliding groove, while protecting the mounting part.

[0010] Preferably, the side of the friction-enhancing block facing the sliding part is an arc-shaped surface, which can prevent the sliding part from moving left or right when the sliding part presses against the friction-enhancing block.

[0011] As a preferred embodiment, two friction blocks are provided, located on the upper and lower sides of the sliding part respectively, and the two friction blocks are connected by springs on the left and right sides. When the sliding part rotates, the two friction blocks are pressed against the upper and lower sides of the slide groove to increase friction, fix the position of the mounting part, and prevent movement.

[0012] In this application, the mounting component extends forward and backward, parallel to the channel steel.

[0013] The mounting component is a sheet metal plate, which is located on the left or right side of the connecting plate.

[0014] Preferably, the angle between the mounting plate and the connecting plate is greater than 90 degrees and less than 130 degrees.

[0015] Furthermore, the maximum angle at which the connecting plate rotates downwards is complementary to the angle between the mounting plate and the connecting plate. When the connecting plate rotates downwards to the maximum angle, it will press against the upper and lower surfaces of the slide groove to fix the position of the mounting component. At this time, the mounting plate is horizontal, which facilitates docking with the mounting holes on the object being mounted.

[0016] In this application, the chute and mounting component are located between two supporting channel steels.

[0017] This utility model provides an easy-to-install dry-type transformer. The mounting component slides along a groove, moving the position of the mounting holes on the mounting plate to correspond with the mounting holes on the mounting surface. This avoids the need to drill new holes or customize matching mounting surfaces. Furthermore, by rotating the mounting component, it can be switched between a sliding position and a fixed position, making adjustment convenient and ensuring the stability of the dry-type transformer after installation.

[0021] The components represented by the various reference numerals in the diagram are:

[0022] 1. Base; 11. Slide groove; 111. Tooth groove; 2. Transformer body; 3. Support channel steel; 4. Mounting parts; 41. Connecting plate; 42. Mounting plate; 43. Sliding part; 44. Friction-increasing block. Detailed Implementation

[0023] like Figure 1 and Figure 2As shown, this embodiment of the utility model provides a dry-type transformer that is easy to install. It is mounted on a mounting surface, which can be a wall panel of a tank or other support rod. However, uniformly, the mounting surface will have mounting holes for fixing the dry-type transformer, and usually multiple holes are arranged in an array. Furthermore, it is understood that, to improve the matching degree of the mounting holes, the mounting holes on the mounting surface are usually strip-shaped holes.

[0024] The dry-type transformer includes a base 1 and a transformer body 2 fixed on the base 1. Two parallel support channel steels 3 are fixed to the bottom of the base 1 for support. This part of the technology is prior art and will not be described in detail here. When the dry-type transformer is placed, the mounting holes on the mounting object extend forward and backward, and the two support channel steels 3 are symmetrically arranged on the left and right, and are parallel to the extension direction of the mounting holes.

[0025] In this embodiment, the base 1 has sliding grooves 11 on both the front and rear surfaces, and the bottom of the base 1 is also provided with a mounting component 4. The mounting component 4 includes a connecting plate 41 and a mounting plate 42. The upper edge of the connecting plate 41 is provided with two sliding parts 43, which respectively cooperate with the two sliding grooves 11. The connecting plate 41 is configured to slide horizontally and rotate vertically through the two sliding parts 43. The mounting plate 42 is connected to the lower edge of the connecting plate 41 and is provided with mounting holes for docking with mounting holes on the object to allow bolts to pass through. The mounting plate 42 can have multiple mounting holes arranged in a front-to-back pattern.

[0026] The sliding part 43 has an elliptical or cam-shaped cross section, and the maximum profile dimension of the cross section is greater than the vertical width of the slide groove 11, while the minimum dimension is less than the vertical width of the slide groove 11.

[0027] When the mounting part 4 rotates from bottom to top, the sliding part 43 rotates and presses against the upper and lower side walls of the slide groove 11, allowing the mounting part 4 to slide along the slide groove 11 and adjust its position to correspond with the mounting hole on the object. When the mounting part 4 rotates from top to bottom, the sliding part 43 rotates and presses against the upper and lower side walls of the slide groove 11, fixing the position of the mounting part 4 and thus fixing the dry-type transformer.

[0028] In this embodiment, the slide 11 and the mounting part 4 are located between the two supporting channel steels 3, but this application is not limited to this. In some other embodiments, they can also be set on both sides of the two supporting channel steels 3.

[0029] The slide groove 11 extends to the left and right, allowing the mounting part 4 to slide left and right.

[0030] Mounting member 4 extends forward and backward, preferably parallel to the channel steel. It is preferably a one-piece molded plate. Mounting plate 42 is located to the left or right of connecting plate 41 and is formed by bending the plate integrally. The angle between mounting plate 42 and connecting plate 41 is greater than 90 degrees and less than 130 degrees. Correspondingly, the maximum angle of rotation of connecting plate 41 from top to bottom is complementary to the angle between mounting plate 42 and connecting plate 41.

[0031] When the connecting plate 41 rotates from top to bottom to the maximum angle, the sliding part 43 presses against the upper and lower surfaces of the sliding groove 11, fixing the position of the mounting part 4. At this time, the mounting plate 42 is horizontal and parallel to the object being mounted, making it convenient to connect with the mounting holes on the object being mounted.

[0032] To improve the locking capability of the base 1, the number of mounting parts 4 can be set to multiple.

[0033] Furthermore, toothed grooves 111 are provided on the lower and / or upper sides of the slide groove 11, arranged densely on the left and right sides to increase friction, so that when the sliding part 43 is pressed against the slide groove 11, relative sliding can be avoided, thereby stably fixing the base 1.

[0034] A friction-enhancing block 44 is also provided between the sliding part 43 and the tooth groove 111, which slides synchronously with the sliding part 43. The friction-enhancing block 44 has teeth that can match the tooth groove 111 on the side facing the tooth groove 111, and the side of the friction-enhancing block 44 facing the sliding part 43 is an arc-shaped surface.

[0035] When the sliding part 43 rotates, it presses the friction-enhancing block 44 against the side wall of the slide groove 11. The teeth on the friction-enhancing block 44 mesh with the tooth grooves 111 on the side wall of the slide groove 11, locking the friction-enhancing block 44 in a locked position relative to the slide groove 11. The side of the friction-enhancing block 44 facing the sliding part 43 is an arc-shaped surface. While allowing the sliding part 43 to rotate, it can also prevent the sliding part 43 from moving left or right when the sliding part 43 presses against the friction-enhancing block 44. This improves the locking degree between the mounting part 4 and the base 1 in this state, and improves the stability of the dry-type transformer after installation.

[0036] Preferably, two friction-enhancing blocks 44 are provided, located on the upper and lower sides of the sliding part 43 respectively, clamping the sliding part 43, and the two friction-enhancing blocks 44 are connected on the left and right sides by springs. When the sliding part 43 rotates downward, it presses the two friction-enhancing blocks 44 tightly against the upper and lower sides of the slide groove 11. When it rotates upward, the two friction-enhancing blocks 44 move towards each other under the action of the springs so as not to affect the sliding of the mounting part 4.

[0037] At the same time, the friction-enhancing block 44 can also act as a gasket to protect the sliding part 43 and prevent the sliding part 43 from being severely worn.

[0038] This utility model embodiment provides a dry-type transformer that is easy to install. When using it, place the dry-type transformer on the mounting surface, rotate the mounting part 4 upwards and slide it left and right to adjust its position so that the mounting holes on the mounting plate 42 correspond to the mounting holes on the mounting surface. Then rotate the mounting part 4 downwards, and the sliding part 43 presses against the sliding groove 11 to lock the position of the mounting part 4. When the mounting part 4 is rotated downwards to the maximum angle, the mounting plate 42 is horizontal and close to the surface of the mounting surface. The mounting part 4 is fixed to the mounting surface by bolts, thereby fixing the dry-type transformer on the mounting surface.

[0039] The adjustable mounting bracket 4 avoids the need for drilling new holes or customizing matching mounting brackets. Furthermore, the mounting bracket 4 is easy to adjust and, when locked, ensures the stability of the dry-type transformer.
