Description

Technical Field

[0001] The present application relates to the technical field of transformer assembly, and in particular to a transformer box cover assembly mechanism. Background Art

[0002] As a crucial component in power systems, oil-immersed transformers typically consist of a sturdy housing, an internal iron core, and a cover. During transformer manufacturing, the cover not only serves as a critical barrier to protect internal components but also requires the pre-assembly of low-voltage and high-voltage porcelain cylinders to ensure secure and stable electrical connections.

[0003] Reference Figure 1 、 Figure 2 and Figure 3 A transformer box cover includes a body 1, on which a low-voltage lower porcelain bottle assembly 11, a low-voltage upper porcelain bottle assembly 12 and a high-voltage porcelain bottle assembly 13 are provided. The low-voltage lower porcelain bottle assembly 11 includes a first sealing ring 111, a low-voltage lower porcelain bottle body 112, a second sealing ring 113 and a lower guide rod 114 fixed to the box cover, wherein both ends of the lower guide rod 114 protrude from the box cover surface; the low-voltage upper porcelain bottle assembly 12 includes a third sealing ring 121, a low-voltage upper porcelain bottle body 122, a first glue bead 123 and a low-voltage upper porcelain cover 124; the high-voltage porcelain bottle assembly 13 includes a fourth sealing ring 131, a high-voltage porcelain bottle body 132, a second glue bead 133 and a high-voltage porcelain cover 134. Three upper guide rods 14 for supporting the high-voltage porcelain bottle assembly 13 are also fixed on the upper surface of the box cover;

[0004] During the assembly process, the first sealing ring 111, the low-pressure lower porcelain bottle body 112, and the second sealing ring 113 are first fixedly mounted on the lower end of the lower guide rod 114 from bottom to top, and then the third sealing ring 121, the low-pressure upper porcelain bottle body 122, the first glue bead 123 and the low-pressure upper porcelain cover 124 are fixedly mounted on the upper end of the lower guide rod 114 from bottom to top; finally, the fourth sealing ring 131, the high-pressure porcelain bottle body 132, the second glue bead 133 and the high-pressure porcelain cover 134 are fixedly mounted on the outer periphery of the upper guide rod 14 from bottom to top.

[0005] However, traditional assembly methods require workers to manually attach each component to the guide rod one by one. This process is not only time-consuming and labor-intensive, but also particularly inefficient in large-scale production environments. With the continued growth in market demand for transformers, improving assembly efficiency and shortening production cycles have become urgent technical challenges, leaving room for improvement.
