Description

Technical Field

[0001] This utility model relates to the field of transformer installation technology, specifically to an installation structure and an oil-immersed transformer using the same. Background Technology

[0002] Oil-immersed transformers are a common type of power transformer. Their core and windings are immersed in insulating oil. Due to their efficient cooling and reliable insulation performance, oil-immersed transformers are widely used in the power and industrial fields. In power systems, they are used in substations and distribution systems for voltage step-up and step-down. In industry, they provide the required voltage for large equipment.

[0003] Transformers are typically installed using a hoisting method. A crossbeam is erected between two columns, and the transformer is hoisted onto the crossbeam. The base frame is then fixed to the crossbeam with bolts. However, during actual installation, the inventors discovered that the existing connection method between the crossbeam and the columns is not stable enough. Furthermore, after the transformer is placed on the crossbeam, it requires fine-tuning to center it. During this adjustment, the hoisted transformer is prone to angular displacement, causing the base frame to deviate from the vertical direction of the crossbeam. After centering, the transformer needs to be rotated for further adjustment. This adjustment process is cumbersome and requires a lot of manual support, making it difficult to operate. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides an installation structure and an oil-immersed transformer using the same.

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

[0006] An installation structure is connected to two columns arranged in parallel. The installation structure includes two support frames disposed on the front and rear sides of the two columns, with both ends of the support frames extending beyond the two columns.

[0007] Multiple support frames are provided between the two columns, and the support frames at both ends are respectively in contact with the two columns. The support frames are arranged perpendicularly to the support frames and can be fixed to the support frames.

[0008] The bottom of each of the two support frames located at both ends is provided with a support component, which can be fixed to the column.

[0009] To save materials while ensuring support strength, the support frame is provided in two parts, and the two support frames are located at the positions that contact the two columns.

[0010] The support component is specifically designed as follows: the support component includes two connecting frames fixed to both ends of the support frame, and the bottom ends of the two connecting frames are connected to a connecting frame. The connecting frame is fastened to the side of the column, and the connecting frame and the connecting frame are fixed by a connecting plate.

[0011] To improve the stability of the support frame, a fastening frame is provided above the support frame, and the fastening frame is located outside the column and parallel to the support frame. The fastening frame is fixedly connected to the support frame.

[0012] In order to facilitate the installation of the transformer by pre-positioning it, a U-shaped frame is installed on the outer end face of the support frame with the opening facing downward. The U-shaped frame can slide along the length of the support frame and can be fixed to it in multiple positions.

[0013] To ensure the balance of the transformer pre-positioning, two U-shaped frames are provided on the outside of each support frame.

[0014] The U-shaped frame and the support frame are installed as follows: a mounting plate is provided in the middle of the U-shaped frame, a fastening bolt is installed through the mounting plate, and the fastening bolt passes through the support plate and is fixed by a fastening nut.

[0015] To facilitate the adjustment of the transformer's position along the length of the support frame after pre-positioning, a waist-shaped hole is provided through the support frame, and the fastening bolt passes through the waist-shaped hole and can slide along it.

[0016] An oil-immersed transformer, using the installation structure described in the claim, has two base frames installed at the bottom of the transformer, the two base frames being installed above two support frames, and a U-shaped frame being fastened to the base frames.

[0017] In order to limit the movement of the U-shaped frame, limit blocks are provided at both ends of the upper surface of the base frame along the length direction.

[0018] The beneficial effects of this utility model are as follows: This utility model is an installation structure and an oil-immersed transformer using the same. By setting support frames on the front and rear sides of the two columns and setting a load-bearing frame between the support frames, a stable frame structure is formed, which significantly enhances the overall stability of the installation structure and avoids the instability problem of the traditional beam and column connection method. The fixed design of the support components and the columns further enhances the stability of the structure, and can support both sides of the support frame to ensure that the transformer will not tilt or shift during installation. The design of multiple U-shaped frames allows the transformer base frame to be quickly snapped onto the support frame, limiting the position of the base frame and fixing it with fastening bolts, so that the support frame and the base frame can be quickly adjusted to a vertical state, simplifying the centering adjustment process of the transformer, improving installation efficiency, and the U-shaped frame can slide along the length of the support frame and be fixed in multiple positions, making the position adjustment of the transformer more flexible and enabling quick centering fine adjustment, avoiding the longitudinal shift of the base frame when centering laterally in the traditional method.

[0028] Example

[0029] As mentioned in the background section, existing oil-immersed transformers are installed by hoisting onto a crossbeam between two columns 1, and then fixed to the crossbeam with bolts. The columns 1 are usually cylindrical or square. However, the existing crossbeam and columns 1 are usually connected by simple clamps, which has poor stability. Furthermore, when adjusting the transformer 11 to be centered, frequent adjustments are required along the horizontal and vertical directions of the crossbeam, making the adjustment method quite complicated. Therefore, the inventors have made improvements and designed a new type of transformer 11 installation structure, which will be described in detail below with reference to the figures.

[0030] This embodiment provides an installation structure and an oil-immersed transformer using the same. The installation structure is described first, see [link to relevant documentation]. Figure 1 and Figure 3This installation structure is installed between two parallel columns 1. The columns 1 can be cylindrical utility poles or square columns, and are connected to the two columns 1. The installation structure includes two support frames 2 set on the front and rear sides of the two columns 1. That is, the extension direction of the support frames 2 is the same as the arrangement direction of the two columns 1. The support frames 2 are U-shaped steel with their openings facing the columns 1. The two ends of the support frames 2 extend beyond the two columns 1 to form a stable frame structure. In addition, multiple load-bearing frames 3 are set between the two columns 1, and the load-bearing frames 3 at both ends are respectively in contact with the two columns 1. The load-bearing frames 3 are arranged perpendicular to the support frames 2 and can be fixed to the support frames 2. In this solution, under the premise of ensuring stable support for the support frames 2, two load-bearing frames 3 are set. The two load-bearing frames 3 are located at the positions in contact with the two columns 1. The load-bearing frames 3 are also made of U-shaped steel and are fixed to the support frames 2 by bolts.

[0031] It should be noted that the support frame 3 and the column 1 can be fixed by a positioning frame. The positioning frame is set to be arc-shaped or square according to the shape of the column 1, and is fastened to the outer side of the column 1. Both ends extend toward the support frame 3 and can be fixed by bolts.

[0032] Based on the above structure, a fastening frame 5 is provided above the support frame 2. The fastening frame 5 is located outside the column 1 and is parallel to the bearing frame 3. It is fixedly connected to the support frame 2 by bolts. By setting the fastening frame 5, the upper ends of the two support frames 2 can be connected and fixed, which improves the stability of the support frame 2.

[0033] One of the key design features of this scheme is the combination of... Figure 2 and Figure 4 A U-shaped frame 6 is installed on the outer end face of the support frame 2. The U-shaped frame 6 has its opening facing downwards and can slide along the length of the support frame 2, and can be fixed in multiple positions. Two U-shaped frames 6 are provided on the outer side of each support frame 2. A mounting plate 7 is provided in the middle of the U-shaped frame 6. A fastening bolt 8 is installed through the mounting plate 7. The fastening bolt 8 passes through the oblong hole 10 on the support frame 2 and is fixed by a fastening nut 9. The design of the oblong hole 10 allows the fastening bolt 8 to slide along it, further improving the flexibility and accuracy of adjustment. By setting up the U-shaped frame 6, the transformer 11 can be pre-positioned during installation, that is, the base frame 12 of the transformer 11 can be kept perpendicular to the support frame 2 for centering adjustment on the support frame 2, which can improve the adjustment efficiency of the transformer 11. The limiting method of the transformer 11 is described below.

[0034] In this embodiment, combined with Figure 1 and Figure 3Each of the two support frames 3 located at both ends is equipped with a support assembly 4 at its bottom. The support assembly 4 can be fixed to the column 1, thereby improving the support effect on the support frame 2. Each support assembly 4 includes two connecting frames 41 and one connecting frame 42. The connecting frame 42 can be designed according to the shape of the column 1, and can be arc-shaped or square. The two connecting frames 41 are fixed to both ends of the support frame 3 respectively, and the connecting frame 42 is fastened to the side of the column 1 and fixed to the bottom end of the connecting frame 41 by a connecting plate 43. The connecting frame 41 and the support frame 3, the connecting frame 41 and the connecting frame 42 and the connecting plate 43 can all be fixed with bolts. This design enhances the connection strength between the support assembly 4 and the column 1, preventing loosening due to vibration or external force.

[0035] The above is a description of the installation structure, combined with Figure 1 This installation structure is mainly used for the installation of oil-immersed transformer 11. The specific installation method is as follows: two base frames 12 are installed at the bottom of transformer 11. The two base frames 12 are installed above two support frames 2. After the position of transformer 11 is finally adjusted, the base frames 12 are connected and fixed to the support frames 2 by bolts. The U-shaped frame 6 is fastened to the base frame 12. After fastening, the fastening bolt 8 passes through the U-shaped frame 6 and the waist-shaped hole 10, and is initially fixed at the rear end by the fastening nut 9. This ensures that the fastening bolt 8 can slide along the waist-shaped hole 10 with the U-shaped frame 6, ensuring that the base frame 12 and the support frame 2 are always in a vertical state. The position of transformer 11 on the support frame 2 is adjusted completely by pushing or other equipment. Finally, the fastening bolt 8 is tightened, and the base frame 12 is fixed to the support frame 2 by bolts.

[0036] In addition, limit blocks 13 are provided at both ends of the upper surface of the base frame 12 along the length direction, that is, at the edge of the base frame 12. By setting the limit blocks 13, the U-shaped frame 6 can be limited to prevent it from falling off the base frame 12 due to the loosening of the fastening nut 9 during movement.
