Description

Technical Field

[0001] This utility model belongs to the field of dry-type transformer technology, and in particular relates to a dry-type transformer core fixing structure. Background Technology

[0002] A dry-type transformer mainly consists of a core, windings, insulation materials, and a casing. The core is typically made of stacked silicon steel sheets and provides the magnetic circuit. The windings are made of copper or aluminum wire and are divided into high-voltage windings and low-voltage windings. The insulation materials are used to isolate the windings from the core and to provide electrical insulation between the windings. The casing protects the internal components of the transformer.

[0003] The core of a dry-type transformer is obtained by stacking several laminations. After the core laminations are completed, clamps are needed to secure the core to prevent it from loosening. If the clamps are not properly secured, the core will loosen, increasing eddy current and hysteresis losses and causing danger. Therefore, we need to design a core fixing structure for dry-type transformers. By adopting a component sliding structure and an arc-shaped plate clamping structure, we can ensure that the core is always kept in the correct position and will not shift, thus ensuring stable operation of the transformer and increasing safety. When it is necessary to inspect, repair, or replace parts of the transformer, the sliding structure facilitates disassembly and installation by the operator, thereby improving installation efficiency and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a dry-type transformer core fixing structure, which adopts a component sliding structure and an arc plate clamping structure to ensure that the core is always kept in the correct position and the core position will not shift, thus ensuring the stable operation of the transformer and increasing the safety of use. When it is necessary to inspect, repair or replace parts of the transformer, the sliding structure facilitates the operator's disassembly and installation, thereby improving the installation efficiency and the safety of use, thus solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dry-type transformer core fixing structure includes two symmetrical clamping I-beams installed on the top of the dry-type transformer. An iron core is arranged between the two clamping I-beams. An arc-shaped plate one and an arc-shaped plate two are fixedly connected to the upper and lower sides of the two clamping I-beams facing each other. The arc-shaped plate one and the arc-shaped plate two are tightly fitted with the iron core. Fixing frames are fixedly connected to the left and right sides of the rear side of the front clamping I-beam. A fixing baffle is fixedly connected to the front side of the fixing frame. A connecting plate is provided in the inner cavity of the fixing frame. Two sliding rods of the same size are fixedly connected to the front side of the connecting plate. Fixing sleeves of the same size are fixedly connected to the rear side of the inner cavity of the fixing frame. The fixing sleeves are slidably connected to the sliding rods. A threaded rod that penetrates to the rear side of the fixing baffle is fixedly connected to the rear side of the connecting plate. The threaded rod penetrates to the surface of the rear clamping I-beam and is threadedly connected to the rear clamping I-beam.

[0006] Preferably, tracks are fixedly connected to both the left and right sides of the bottom of the inner cavity of the fixed frame.

[0007] Preferably, the inner walls of both tracks are slidably connected to two symmetrical sliding blocks, which are fixedly connected to the connecting plate.

[0008] Preferably, a spring is fitted onto the surface of the fixing sleeve and the slide rod, and the two ends of the spring are welded to the fixing frame and the connecting plate, respectively.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses the combined use of a clamping I-beam plate, an arc-shaped plate one, and an arc-shaped plate two to fix the surface of the iron core, ensuring that the iron core will not shift or loosen. Then, through the combined use of a sliding block, a fixing sleeve, and a sliding rod, the connecting plate drives the threaded rod to pass through the surface of the clamping I-beam plate, thereby enabling the clamping I-beam plate to fix the iron core in place. This achieves the goal of using a component sliding structure and an arc-shaped plate clamping structure to ensure that the iron core is always kept in the correct position and will not shift, ensuring the stable operation of the transformer and increasing safety. When it is necessary to inspect, repair, or replace parts of the transformer, the sliding structure facilitates disassembly and installation by the operator, thereby improving installation efficiency and safety.

[0013] 2. This utility model uses the cooperation of the track and the sliding block so that the track limits the sliding block when the sliding block drives the connecting plate to slide, ensuring that the sliding block will not lose contact with the track when moving, thus improving the stability of the sliding block during the movement process.

[0014] 3. By incorporating springs, this utility model allows the connecting plate to move more smoothly due to its elasticity, maintaining a relatively stable motion. The springs' buffering effect ensures smoother movement, and their reset function ensures the connecting plate can quickly and accurately return to its starting position, thus improving the system's accuracy and reliability.

[0015] 4. The push handle in this utility model applies force when the connecting plate is pushed to move the threaded rod, which facilitates the operation of the user. Attached Figure Description

[0024] In the following description, embodiments of the dry-type transformer core fixing structure of this utility model will be described with reference to the accompanying drawings.

[0025] Figure 1-5 This invention illustrates a dry-type transformer core fixing structure according to an embodiment of the present invention. It includes two symmetrical clamping I-beams 2 mounted on the top of the dry-type transformer 1. A core 3 is disposed between the two clamping I-beams 2. Arc-shaped plates 4 and 5 are fixedly connected to the upper and lower sides of the opposing sides of the two clamping I-beams 2, respectively. Arc-shaped plates 4 and 5 are tightly fitted to the core 3. Fixing frames 6 are fixedly connected to the left and right sides of the rear side of the front clamping I-beams 2. Fixing baffles 7 are fixedly connected to the front side of the fixing frames 6. Rails are fixedly connected to the left and right sides of the bottom of the inner cavity of the fixing frames 6. The inner walls of both tracks 8 are slidably connected to two symmetrical sliding blocks 9. The sliding blocks 9 are fixedly connected to the connecting plate 10. Through the cooperation of the tracks 8 and the sliding blocks 9, the tracks 8 limit the sliding blocks 9 as they slide, ensuring that the sliding blocks 9 do not disengage from the tracks 8 during movement, thus improving the stability of the sliding blocks 9 during movement. The inner cavity of the fixed frame 6 is equipped with a connecting plate 10. Two symmetrical sliding rods 12 are fixedly connected to the front side of the connecting plate 10, and two symmetrical fixing rods 12 are fixedly connected to the rear side of the inner cavity of the fixed frame 6. Sleeve 11, fixed sleeve 11 is slidably connected to slide rod 12. Spring 13 is sleeved on the surface of fixed sleeve 11 and slide rod 12. The two ends of spring 13 are welded to fixed frame 6 and connecting plate 10 respectively. Through the setting of spring 13, the elasticity of spring 13 can make the movement of connecting plate 10 more stable, so that connecting plate 10 maintains a relatively stable movement state. The buffering effect of spring 13 can ensure that the movement of connecting plate 10 is more stable. The reset function of spring 13 can ensure that connecting plate 10 can quickly and accurately return to the starting position, improving the accuracy and reliability of the system. The rear of connecting plate 10 A threaded rod 14 is fixedly connected to the side and extends to the rear side of the fixed baffle 7. The threaded rod 14 extends to the surface of the rear clamping I-beam 2 and is threadedly connected to the rear clamping I-beam 2. A push handle 15 is fixedly connected to the top of the connecting plate 10 and extends to the top of the fixed frame 6. The push handle 15 is slidably connected to the fixed frame 6. The push handle 15 provides force when pushing the connecting plate 10 to move the threaded rod 14, which facilitates the user's operation. A square groove for the push handle 15 to slide is provided on the surface of the fixed frame 6, and a round hole for the threaded rod 14 to pass through is provided on the surface of the fixed baffle 7.

[0026] Working principle: When using this utility model, the user installs the I-beam plate 2 on the top surface of the iron core 3 by clamping it. This allows the arc-shaped plate 4 and arc-shaped plate 5 to clamp the iron core 3, ensuring that the iron core 3 will not loosen during installation and preventing any danger caused by loosening. Then, the two clamping I-beam plates 2 are aligned and fixed. Subsequently, the push handle 15 is pushed, which causes the connecting plate 10 to slide within the cavity of the fixed frame 6. This causes the connecting plate 10 to drive the sliding block 9 to slide within the cavity of the track 8. This causes the connecting plate 10 to slide the slide rod 12 within the inner cavity of the fixed sleeve 11, causing the spring 13 to elastically lengthen. Consequently, the connecting plate 10 causes the threaded rod 14 to pass through to the front side of the fixed baffle 7, allowing the threaded rod 14 to pass through the rear side of the clamping I-beam 2. This allows the user to rotate the nut onto the surface of the threaded rod 14, which then fixes the threaded rod 14 to the clamping I-beam 2. Finally, the arc plate 1 4 and arc plate 2 5 provide stable fixation for the iron core 3, ensuring that the iron core 3 will not loosen during use.

[0027] In summary, this dry-type transformer core fixing structure, through the coordinated use of clamping I-beam plate 2, arc-shaped plate 4, and arc-shaped plate 5, fixes the surface of the core 3, ensuring that the core 3 does not shift or loosen. Then, through the coordinated use of sliding block 9, fixing sleeve 11, and sliding rod 12, connecting plate 10 drives threaded rod 14 to penetrate to the surface of clamping I-beam plate 2, thereby achieving the effect of fixing the core 3. Thus, by using a component sliding structure and arc-shaped plate clamping structure, the core is always kept in the correct position, preventing displacement and ensuring stable transformer operation, increasing safety. When the transformer needs inspection, maintenance, or component replacement, the sliding structure facilitates disassembly and installation by the operator, thereby improving installation efficiency and operational safety.
