[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. They are mainly composed of cores made of silicon steel sheets and coils cast with epoxy resin. Insulating cylinders are placed between high and low voltage coils to increase electrical insulation, and the coils are supported and constrained by pads. The fasteners overlapping its components have anti-loosening properties.

[0003] The existing dry-type transformers that are easy to disassemble and assemble have the problem that it is inconvenient to strongly reduce the vibration of the transformer body. For example, the Chinese utility model patent with the authorization announcement number CN215815482U discloses a dry-type transformer that is easy to disassemble and assemble. The installation and disassembly of the overall device is also relatively simple, which is convenient for later maintenance. However, this device is not convenient for strongly reducing the vibration of the transformer body.
