Description

Technical Field

[0001] The utility model relates to transformer assembly technology, in particular to a three-phase integrated transformer assembly force-bearing platform. Background Art

[0002] During the assembly process of the transformer, the coil is an elastic element, and its axial height is usually greater than the value required during the assembly process when no pressure is applied or insufficient pressure is applied. This is because the coil usually has a certain height deviation due to the resilience of the material during the manufacturing process. In order to ensure that the transformer has good mechanical and electrical properties during operation, a further compaction process is required to complete the installation of the coil in the final assembly stage. At this stage, the lead work and coil assembly of the transformer have been completed, so the requirements for the compaction process are more stringent and precise.

[0003] However, there are great limitations to simply relying on the body structure for compression. This is because the internal structure of the transformer usually contains multiple layers of compressed parts, such as coils, insulation materials, etc., which need to be subjected to uniform pressure during assembly. If excessive concentrated pressure is applied to a single part, it may cause cracking of the laminate. This cracking will not only damage the appearance of the transformer, but may also seriously reduce its mechanical properties, causing problems during the operation of the transformer and affecting its stability and life. Therefore, how to effectively and evenly apply pressure to avoid cracking of the laminate is a key issue during the transformer assembly process.

[0004] Traditional assembly methods can usually only meet the assembly requirements of single-phase transformers. In this method, each phase of the transformer needs to be assembled and pressed separately, which not only increases the complexity and time cost of assembly, but also may cause uneven force between phases, affecting the overall performance of the transformer. Especially for three-phase transformers, since each phase needs to be assembled separately, the assembly efficiency is low, which is difficult to meet the needs of fast and efficient assembly of modern transformers. Utility Model Content

[0005] The utility model aims to provide a three-phase integrated transformer assembly force bearing platform to solve the problem that the prior art has low assembly efficiency and is difficult to meet the needs of fast and efficient assembly of modern transformers because each phase needs to be assembled separately.

[0006] The utility model is realized through the following technical scheme: a three-phase integrated transformer assembly force-bearing platform, comprising an upper platform and a lower platform; the upper platform and the lower platform are arranged opposite to each other and a transformer body is arranged between them, a fixing frame is arranged between the upper platform and the transformer body, a groove is arranged at the bottom of the fixing frame, and a hydraulic cylinder is arranged in the groove.

[0007] Preferably, it further comprises a middle support platform, wherein the middle support platform is arranged between the upper platform and the lower platform.

[0008] Preferably, the middle support platform is perpendicular to the upper platform and the lower platform.

[0009] Preferably, the upper platform and the lower platform are both planar structures.

[0010] Preferably, it further comprises a support plate, wherein the support plate is arranged between the hydraulic cylinder and the fixing frame.

[0011] Preferably, the support plates are mounted on both sides of the fixing frame and form an integral structure with the fixing frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The precise clamping control of the transformer body can be achieved by using the hydraulic cylinder and the fixing frame. The hydraulic cylinder is set in the slot to ensure its stability when lifting or applying force. The fixing frame fixes the cylinder through the slotted structure to ensure the stability of the hydraulic cylinder during operation and avoid structural damage caused by uneven pressure.

[0014] The structural stability is improved. The utility model ensures the stability and load-bearing capacity of the entire assembly platform through the combination of the upper platform, the lower platform and the middle support platform. The upper platform and the lower platform are both planar structures, arranged above and below the transformer body, and the middle support platform vertically connects the upper and lower platforms, further enhancing the stability of the platform.

[0015] The hydraulic cylinder can accurately control the pressure applied to the transformer body, avoiding the problem of excessive pressure concentration in a single part.

[0016] By adding a support plate between the hydraulic cylinder and the fixed frame, the operability and force uniformity of the assembly platform are further enhanced, ensuring that each phase of the transformer is subjected to uniform force during the assembly process and effectively preventing the laminate from cracking.

[0017] The three-phase integrated design enables the three-phase transformer to be assembled simultaneously, which greatly improves the assembly efficiency compared to the traditional method of assembling each phase separately. For high-voltage transformers, it reduces the time of body leakage during assembly, thereby improving the overall performance of the transformer. BRIEF DESCRIPTION OF THE DRAWINGS
