Description

Technical Field

[0001] The utility model relates to the field of transformer casings, in particular to a transformer casing with a fixed structure. Background Art

[0002] The transformer enclosure is a crucial component of the transformer, protecting not only its internal components but also the external environment. Typically constructed from metal materials such as steel or aluminum, the enclosure offers excellent mechanical strength and corrosion resistance. The enclosure's design must meet certain safety standards to ensure it effectively limits and directs fault currents in the event of a fault, protecting equipment and personnel. Furthermore, the enclosure may include heat sinks or other cooling devices to dissipate the heat generated by the transformer during operation.

[0003] In current applications, transformer enclosures typically feature a fixed structure to ensure stable mounting during operation. To achieve this, an L-shaped mounting bracket is commonly used to secure the transformer enclosure. This bracket is widely adopted for its simplicity and ease of use. However, this mounting method presents a significant problem during transportation: parts can fall off during transport, resulting in missing parts. This loss not only impacts equipment installation but can also require additional time and cost to replace the missing parts.

[0004] Another common method for securing the transformer casing is to weld mounting bars to the transformer housing. While this method provides a relatively secure fix in some situations, it presents another problem during transportation. Because the mounting bars are welded, they can be squeezed or impacted during transportation, causing them to deform. This deformation not only affects the proper function of the mounting bars but can also further compromise the installation of the transformer casing, ultimately affecting the performance and stability of the entire equipment.

[0017] The interplay of the fixed and storage structures ensures the safety and space efficiency of the transformer housing during transportation. The upper metal bars and lower mounting brackets can be folded or disassembled and safely stored in their corresponding storage compartments, preventing damage from shaking or collisions during transportation.
