When the dry-type transformer is used, the conventional dry-type transformer is generally installed in some places with large-scale equipment, the large-scale equipment can generate a large amount of vibration in the operation process, and in order to prevent the dry-type transformer from being damaged due to the vibration, a damping device is generally installed at the bottom of the transformer. However, the existing damping devices require modification of the transformer housing during installation and cannot be reused on other transformers once installed.

Therefore, it is urgently needed to provide a reusable damping base for a dry-type transformer to solve the technical problems.
