Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an inclined top hat type transformer transportation protective cover. Background Art

[0002] In recent years, with the continuous growth of power demand and the accelerating construction of the power grid, large transformers have been more and more widely used. However, there is a significant problem in the transportation process of large transformers, that is, the increase in transportation height has led to a significant increase in transportation costs. This is because the height of large transformers often exceeds the limits of standard transportation tools, thus special transportation equipment and routes need to be adopted, increasing the transportation difficulty and cost.

[0003] The transformer transportation cover is installed on the transformer riser, and the transformer riser is inclined. Traditional transformer transportation covers usually adopt a fixed structure and cannot be flexibly adjusted according to the inclination angle of the transformer riser and transportation requirements. This makes the effect of traditional transportation covers in reducing the transportation height of transformers limited and unable to effectively solve the cost problem caused by the increase in transportation height. In addition, the performance of traditional transportation covers in aspects such as sealing and mechanical strength verification is also insufficient and difficult to meet the high requirements for transportation protection of large transformers. Content of the Utility Model

[0004] The utility model aims at the deficiencies of the prior art and provides an inclined top hat type transformer transportation protective cover.

[0005] The utility model is realized through the following technical solutions. There is provided an inclined top hat type transformer transportation protective cover, including a main body pipe. The lower end of the main body pipe is connected to the transformer riser, and the upper end of the main body pipe is provided with a horizontal installation surface. An upper top cover is installed on the installation surface. A support plate is fixedly connected inside the main body pipe, and a transformer lead wire through hole is opened on the support plate. In this solution, taking the plane at the highest point of the inclined transformer cover as the reference plane, the cap part of the top hat is cut flat. Such a design can not only retain the beauty and practicability of the top hat type transportation cover but also effectively reduce the height of the transportation cover. The cutting position is reasonably arranged according to the specifications of the transformer outgoing copper stranded wires and the position of the inclined tip, which not only ensures the smooth lead-out of the cables but also avoids the increase in transportation height caused by cable accumulation. The transformer lead wire passes upward through the transformer lead wire through hole and then is coiled on the support plate.

[0006] As an optimization, the lower end of the main body pipe is flange-connected to the transformer riser. This makes the installation, disassembly, and maintenance processes more convenient and feasible.

[0007] As an optimization, the upper end of the main body pipe is flange-connected to the upper top cover. This makes the installation, disassembly, and maintenance processes more convenient and feasible.

[0008] As an optimization, the main pipe is coaxially arranged with the transformer riser. Therefore, it is convenient for the connection between the main pipe and the transformer riser.

[0009] As an optimization, a plug seat is installed on the upper top cover. The plug seat provides great convenience for pressure testing for leakage and verifying mechanical strength. By conducting pressure testing through the plug seat, the sealing performance of the protective cover under the required pressure can be effectively detected, so as to timely discover and solve potential leakage problems, and it has excellent impact resistance, dust prevention and moisture protection performance.

[0010] As an optimization, the support plate is parallel to the lower end of the main pipe.

[0011] The beneficial effects of the present utility model are as follows: A beveled top hat type transformer transportation protective cover of the present utility model has a unique design and novel structure. It can be flexibly adjusted according to the actual size and transportation requirements of the transformer, effectively reducing the transportation height, thereby reducing the need for special transportation equipment and routes and lowering the transportation cost. At the same time, the protective cover is convenient for verifying the sealing performance and mechanical strength, and performs excellently in aspects such as impact resistance, dust prevention and moisture protection, providing comprehensive and reliable protection for large transformers.

[0012] The present utility model effectively reduces the height of the transformer during transportation, reduces the transportation space and cost. It maintains the basic protection function of the transportation cover and does not affect the coiling and protection of the outgoing copper stranded wires. It has a simple structure, is easy to implement, and has good practicability and economy. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As Figures 1 to 4As shown in the figure, a beveled top hat-shaped transformer transportation protective cover of the present utility model includes a main body tube 3. The main body tube 3 is a circular tube and is located above the transformer riser 2. In this embodiment, the transformer riser 2 is a circular tube and is vertically inclined. The lower end of the transformer riser 2 is connected to the transformer tank cover 1.

[0021] The lower end of the main body tube 3 is connected to the transformer riser 2, and the main body tube 3 is coaxially arranged with the transformer riser 2. The diameter of the main body tube 3 is smaller than that of the transformer riser 2. The lower end of the main body tube 3 is flange-connected to the transformer riser 2. Specifically, a lower flange plate 5 is welded to the lower end of the main body tube 3, and the lower flange plate 5 is connected to the flange plate at the upper end of the transformer riser 2.

[0022] The upper end of the main body tube 3 is provided with a horizontal mounting surface. Since the main body tube 3 is coaxially and inclined with the transformer riser 2, the angle between the mounting surface at the upper end of the main body tube 3 and the axis of the main body tube 3 is not 90 degrees.

[0023] An upper top cover 4 is installed on the mounting surface. The upper end of the main body tube 3 is flange-connected to the upper top cover 4. Specifically, an upper flange plate 7 is welded to the upper end of the main body tube 3, and the upper top cover 4 is connected to the upper flange plate 7.

[0024] A plug seat 6 is installed on the upper top cover 4, which provides great convenience for pressure testing for leakage and verifying mechanical strength. By performing pressure testing through the plug seat, the sealing performance of the protective cover under the required pressure can be effectively detected, so as to timely discover and solve potential leakage problems, and it has excellent shock resistance, dust prevention and moisture protection performance.

[0025] A support plate 8 is fixedly connected inside the main body tube 3, and the support plate 8 is parallel to the lower end of the main body tube 3. The support plate 8 is welded in the inner hole of the main body tube 3. A transformer lead wire through hole is opened on the support plate 8, so that it is convenient for the transformer lead wire 9 to pass upward and be placed on the support plate 8.

[0026] The using method of the present utility model:

[0027] The lower end of the main body tube 3 is flange-connected to the transformer riser 2. The upper end of the main body tube 3 is flange-connected to the upper top cover 4. By performing pressure testing through the plug seat 6 on the upper top cover 4, the sealing performance of the protective cover under the required pressure can be effectively detected, so as to timely discover and solve potential leakage problems, and it has excellent shock resistance, dust prevention and moisture protection performance.

[0028] Taking the plane at the highest point of the inclined transformer tank cover as the reference plane, the cap part of the top hat is cut flat. Such a design can not only retain the aesthetics and practicality of the top hat-shaped transportation cover, but also effectively reduce the height of the transportation cover. The cutting position is reasonably arranged according to the specifications of the transformer lead copper stranded wire and the position of the inclined tip, which not only ensures the smooth extraction of the cable, but also avoids the increase in transportation height caused by cable accumulation.
