[0002] With the continuous development of science and technology and the continuous progress of society, transformers have become an important part of the power system. However, when natural disasters such as earthquakes occur, the transformer itself does not have the ability to resist earthquakes and may be damaged, which will have a serious impact on the power system. Therefore, how to improve the earthquake resistance of transformers has become an important issue that needs to be solved in the field of power systems.

[0003] At present, the transformer seismic technology mainly adopts the following measures: 1. Use high-strength materials, which can greatly improve the structural strength of the transformer, thereby enhancing its seismic resistance; 2. Install shock absorbers, which can offset the impact of earthquakes on the transformer, thereby protecting the transformer from damage. However, these measures still have some problems, such as the high cost of high-strength materials and the need to further improve the stability of shock absorbers. Utility Model Content
