Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer corrugated oil tank shell. Background Art

[0002] The design of the transformer corrugated oil tank is mainly to meet the heat dissipation requirements of the transformer and adapt to the expansion of the oil. The corrugated design can increase the surface area of ​​the oil tank, thereby improving the heat dissipation efficiency. At the same time, this design also allows the oil tank to expand or contract freely when the temperature changes, avoiding damage caused by thermal expansion and contraction.

[0003] Announcement No. CN 205751778 U discloses a detachable transformer oil tank shell. When the movable bracket and the fixed bracket can fasten the shell, the bolts are tightened so that the brackets can freely adjust the spacing according to the different shell sizes. During the production process, it is no longer necessary to configure a separate bracket for each shell, which greatly reduces the production cost and cycle.

[0004] The detachable transformer oil tank shell can be fixed by a bracket, but the shell arranged on the device is fixed by bolts. When the shell needs to be disassembled, multiple bolts need to be rotated. When the bolts are rusted, the bolts are difficult to tighten, which affects the work efficiency. Therefore, improvement is needed. Utility Model Content
