Description

Technical Field

[0001] The utility model belongs to the technical field of dry-type transformers, and particularly relates to a slide rail structure and a transformer. Background Art

[0002] A dry-type transformer is one whose core and windings are not immersed in insulating oil; instead, the insulating medium is air or another dry gas. Dry-type transformers are used in a variety of applications, including power systems, industry, construction, commerce, IT, wind and solar power generation systems, rail transportation systems, and medical equipment. In recent years, dry-type transformers have become increasingly popular due to their low partial discharge, excellent fire resistance, strong short-circuit resistance, easy maintenance, and attractive appearance.

[0003] When dry-type transformers are installed in a distribution room, the foundation is generally made of pre-embedded flat steel in a cement floor, and the transformer is welded to the flat steel. The disadvantage of this method is that the transformer is not easy to move after installation. If the transformer needs to be removed for maintenance, it is necessary to first cut the welds between the transformer and the flat steel, separate the transformer from its existing fixed position, and then move the transformer. This process is not only time-consuming and labor-intensive, but may also cause certain damage to the transformer and the pre-embedded flat steel. After moving, it needs to be re-welded and fixed. This process is relatively cumbersome, very inconvenient, and takes a long time. Summary of the Invention

[0004] The utility model provides a slide rail structure and a transformer, which solves the problem in the prior art that the transformer cannot be moved conveniently.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a slide rail structure, including a pulley, a built-in slide rail and an extended slide rail. The pulley is installed on the built-in slide rail, and the built-in slide rail is installed on the transformer foundation. In the working state, the pulley is installed at the lower part of the transformer base, and the extended slide rail and the built-in slide rail are obliquely connected.

[0006] Furthermore, the pulley includes a wheel clamp, a wheel and a wheel axle, the wheel clamp is fixedly connected to the transformer base, and the wheel clamp is rotationally connected to the wheel through the wheel axle.

[0007] Furthermore, a baffle is fixed on one end of the wheel axle, and a pin hole is opened on the other end, and a pin is inserted into the pin hole.

[0008] Furthermore, the main body of the built-in slide rail is a channel steel, a bottom plate is fixed to the side of the channel steel, and a fixing bracket is welded on the bottom plate. When the transformer does not need to be moved, the fixing bracket is connected to the transformer base through fasteners.

[0009] Furthermore, earrings are fixed on the outer side of the built-in slide rail.

[0010] Furthermore, the ends of the built-in slide rail and the extended slide rail are both inclined surfaces, and the sum of the inclination angles of the inclined surfaces of the built-in slide rail and the extended slide rail is 180 degrees.

[0011] A dry-type transformer comprises a transformer body and the above-mentioned slide rail structure, wherein a transformer base is mounted at the lower end of the transformer body, a pulley is mounted at the lower end of the transformer base, and the pulley is located in a built-in slide rail. The transformer body, transformer base and built-in slide rail are all located in an outer shell, and an openable door is mounted on the side wall of the outer shell.

[0012] Furthermore, the shell includes a frame, a panel and a door; the front and rear sides of the frame are equipped with doors, and the other two sides are equipped with panels. The frame is fixed to the transformer base, and the panel has ventilation and heat dissipation holes arranged in an array. The panel and the frame are assembled together.

The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Example 1

[0038] Reference Figure 1 and Figure 2 A transformer with a slide rail structure includes a transformer body 1, a base 2, a pulley 3, a built-in slide rail 4, an extended slide rail 6 and a shell 5.

[0039] The transformer body 1 includes an iron core, a high-voltage coil and a low-voltage coil; the transformer body 1 and the transformer base 2 are fixedly connected by welding or bolting.

[0040] The transformer base 2 and the pulley 3 are fixed by bolts. The pulley 3 is placed on the built-in slide rail 4. The built-in slide rail 4 is fixed to the transformer foundation. The shell 5 covers the transformer body 1 and the transformer base 2. The extended slide rail 6 is connected to the built-in slide rail 4 at an angle to ensure that during operation, when the extended slide rail 6 moves slightly in the axial direction, the extended slide rail 6 and the built-in slide rail 4 still partially overlap.

[0041] like Figures 3 to 5 As shown, the pulley consists of a wheel clamp 301, a wheel 302, an axle 303, and a pin 304. The wheel clamp is bent into a U-shape from steel plate, with a hole drilled in the top for bolt connection to the hole in the transformer base 2. A hole is drilled in the side of the U-shaped wheel clamp for the axle 303 to pass through. A hole is drilled in the center of the wheel 302, which is connected to the wheel clamp 301 as a whole via the axle 303. The wheel 302 can rotate via the axle. The axle 303 is made of round steel, with a circular baffle welded to one end and a small hole drilled in the other end for the pin 304 to pass through. The pin 304 prevents the wheel axle from falling off.

[0042] like Figures 6 to 8 As shown, the main body of the built-in slide rail 4 is a channel steel with an inclined end. Earrings 403 are welded on the outer side of the channel steel to fix the slide rail; a bottom plate 405 is also welded on the side of the channel steel, and a fixing bracket 401 is welded on the bottom plate 405. When the transformer does not need to be moved, the fixing bracket 401 is connected to the transformer base 2 with bolts, thereby preventing the pulley from rolling when the transformer is running and causing the transformer to move.

[0043] like Figure 9 As shown, the housing 5 is a rectangular three-dimensional shape, and the transformer body 1 and the transformer base 2 are installed in the housing 5; the housing 5 consists of a frame 501, a panel 502 and a door 503; the frame 501 is fixed to the foundation, and the panel 502 has ventilation and heat dissipation holes and is assembled with the frame with bolts; doors 503 are left at the front and back of the frame 501.

[0044] Reference Figures 10 to 12 The extended slide rail 6 is made of channel steel and has an inclined surface at its end. When the transformer is in operation, the extended slide rail 6 can be stored elsewhere. When the transformer needs to be pulled out, the folding door 503 of the housing 5 can be opened, and the connection between the fixed bracket 401 of the internal slide rail 4 and the transformer base 2 can be loosened. The extended slide rail 6 is placed outside the housing and docked with the internal slide rail 4, becoming an extension of the internal slide rail 4. The pulley rolls along the internal slide rail 4 and the extended slide rail 6, thereby moving the transformer out of the housing 5.

[0045] The present embodiment provides a transformer slide rail structure, which achieves the purpose of removing the transformer without removing the shell through the cooperation between the pulley, the slide rail, and the shell, and prevents the transformer from being displaced due to vibration generated by the operation of the transformer.

[0046] Example 2

[0047] This embodiment provides a slide rail structure, including a pulley 3 , a built-in slide rail 4 and an extended slide rail 6 .

[0048] The pulley 3 is mounted on the lower end of the transformer base 2 to be moved and is located on the built-in slide rail 4. The built-in slide rail 4 is fixed on the transformer foundation. The extended slide rail 6 and the built-in slide rail 4 are connected at an oblique surface.

[0049] like Figures 3 to 5As shown, the pulley comprises a wheel clamp 301, a wheel 302, an axle 303, and a pin 304. The wheel clamp 301 is formed by bending a steel plate into a U-shape, with a hole drilled in the upper portion. Bolts pass through this hole and connect the two to the hole in the transformer base 2. Holes are drilled through the sidewalls of the U-shaped wheel clamp, and a through hole is provided in the center of the wheel 302. The axle 303 passes through these three through holes, connecting the wheel 302 to the wheel clamp 301, allowing the wheel 302 to rotate. The axle 303 is made of round steel, with a circular baffle welded to one end and a pin hole drilled at the other end. A pin 304 is inserted into the pin hole to prevent the wheel axle 303 from falling off.

[0050] like Figures 6 to 8 As shown, the main body of the built-in slide rail 4 is a channel steel, and the end of the channel steel is a slope with an inclination angle of 45 degrees. Two sets of earrings are welded to the outer side of the channel steel to fix the slide rail, and each set of earrings includes two earrings 403 symmetrically arranged about the channel steel; two sets of bottom plates 405 are also welded to the side of the channel steel, and each set of bottom plates includes two bottom plates 405 symmetrically arranged about the channel steel. A fixing bracket 401 is welded to the upper end surface of the bottom plate 405. When the transformer does not need to be moved, the bracket 401 is connected to the transformer base 2 with bolts or other fasteners to prevent the transformer from sliding or rolling.

[0051] In this embodiment, grooves are formed at both ends of the built-in slide rail 4 .

[0052] like Figure 9 As shown, the housing 5 is a rectangular three-dimensional shell, which covers the transformer body 1 and the transformer base 2; the housing 5 includes a frame 501, a panel 502 and a door 503; the frame 501 is installed with a top plate on the top surface, the front and rear sides are installed with doors 503, and the other two sides are installed with panels 502; the frame 501 is fixed to the transformer foundation, and the panel 502 is provided with an array of ventilation and heat dissipation holes. The panel 502 is assembled with the frame by bolts; the door 503 is a folding door with a window and a lock installed at the bottom.

[0053] Reference Figures 10 to 12 The extension slide rail 6 is made of channel steel, and both ends are inclined at 135 degrees.

[0054] One end of the extended slide rail 6 connected to the built-in slide rail 4 has a protrusion adapted to the above-mentioned groove. When the transformer needs to be moved, the protrusion is inserted into the groove opened at the end of the built-in slide rail 4.
