Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing, and in particular to a split-type transformer oil storage tank. Background Technology

[0002] Traditional oil storage tanks are prone to shaking during long-term use due to vibrations generated by transformer operation, external wind loads, or seismic forces. Additionally, the small contact area between the tank and its support frame can lead to stress concentration, causing the connection points to bear significant localized pressure. Under prolonged pressure or impact, these connections are susceptible to deformation or damage. These issues not only affect the stability of the oil storage tank itself but can also cause loosening or breakage of connecting bolts, ultimately threatening the safe operation of the entire transformer.
