Abstract
Description
Technical Field
[0001] The utility model relates to a sunken transformer cover, belonging to the technical field of transformers. Background Technique
[0002] Transformer switches are usually installed on the transformer cover, which not only increases the volume of the transformer oil tank, but also has a relatively low utilization rate of the internal space of the oil tank. During the transportation of the transformer, there may also be risks such as electric leakage of the transformer. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sunken transformer cover, which can improve the utilization rate of the internal space of the oil tank, effectively reduce the volume of the oil tank, and at the same time avoid the risk of electric leakage generated during the transportation of the transformer, and solve the problems existing in the background technique.
[0004] The technical solution of the utility model is as follows:
[0005] A sunken transformer cover includes an oil tank cover, a connecting steel plate I, a connecting steel plate II, and a sunken cover for switch installation. The sunken cover for switch installation is located below the oil tank cover and is arranged parallel to the oil tank cover. The oil tank cover and the sunken cover for switch installation are connected together by the connecting steel plate I and the connecting steel plate II.
[0006] The upper ends of the connecting steel plate I and the connecting steel plate II are respectively welded to the oil tank cover, the lower ends of the connecting steel plate I and the connecting steel plate II are respectively welded to the sunken cover for switch installation, and the connecting steel plate I and the connecting steel plate II are welded to each other.
[0007] The upper ends of the connecting steel plate I and the connecting steel plate II are respectively welded to the oil tank cover to form rounded weld feet, the lower ends of the connecting steel plate I and the connecting steel plate II are respectively welded to the sunken cover for switch installation to form rounded weld feet, and the connecting steel plate I and the connecting steel plate II form rounded weld feet between them.
[0008] Both the connecting steel plate I and the connecting steel plate II are rectangular steel plates.
[0009] All the rounded weld feet are rounded weld feet with R10.
[0010] The beneficial effects of the utility model are: improving the utilization rate of the internal space of the oil tank, effectively reducing the volume of the oil tank, and at the same time avoiding the risk of electric leakage generated during the transportation of the transformer.

[0016] In the figure: fuel tank cover 1, connecting steel plate I 2, connecting steel plate II 3, sunken cover 4 for switch installation. Specific implementation manner
[0017] The following further illustrates the present utility model through examples in conjunction with the attached drawings.
[0018] Referring to the attached Figures 1-5 , a sunken transformer cover includes a fuel tank cover 1, a connecting steel plate I 2, a connecting steel plate II 3, and a sunken cover 4 for switch installation. The sunken cover 4 for switch installation is located below the fuel tank cover 1 and is arranged parallel to the fuel tank cover 1. The fuel tank cover 1 and the sunken cover 4 for switch installation are connected together through the connecting steel plate I 2 and the connecting steel plate II 3.
[0019] In this example, referring to the attached Figure 1 , the sunken transformer cover includes a fuel tank cover 1, a connecting steel plate I 2, a connecting steel plate II 3, and a sunken cover 4 for switch installation. The sunken cover 4 for switch installation and the fuel tank cover 1 are not in the same plane. The sunken cover 4 for switch installation is located below the fuel tank cover 1 and is arranged parallel to the fuel tank cover 1, forming a "sunken" effect.
[0020] During welding, the sunken cover 4 for switch installation is located below the connecting steel plate I 2 and the connecting steel plate II 3. A welding step with a size of about h = 8 mm is left at the contact position with the connecting steel plate I 2 and the connecting steel plate II 3. A rounded weld bead with R10 is required here; at the contact position between the connecting steel plate I 2 and the connecting steel plate II 3 and the fuel tank cover 1, an 8-mm welding step is also left, and a rounded weld bead with R10 is welded; an 8-mm welding step is also left between the connecting steel plate I 2 and the connecting steel plate II 3, and a rounded weld bead with R10 is welded; other contact positions are welded with normal corner welds.
[0021] The transformer switch is usually installed on the sunken cover 4 for switch installation, which improves the utilization rate of the internal space of the fuel tank, effectively reduces the volume of the fuel tank, and at the same time avoids the risk of electric leakage generated during the transportation of the transformer.
