Description

Technical Field

[0001] This utility model relates to the technical field of transformer oil tank covers, and in particular to a cover for a transformer oil tank. Background Technology

[0002] The transformer oil conservator is installed on the transformer's oil tank. There is also a glass-sealed pipe called an explosion-proof pipe. This is to prevent the oil from being damaged if the oil temperature rises rapidly and the volume expands drastically when the transformer fails. If the oil conservator can no longer hold the oil, the oil flow will break the glass and rush out of the explosion-proof pipe, protecting the transformer from major damage.

[0003] Patent 202420529985.6 includes a fuel tank assembly, which includes a tank body with a radiator fixedly connected to the surface of the tank body. A cover assembly is provided on the top of the fuel tank assembly, which includes a cover plate that is movably installed on the top of the tank body. When maintenance is required inside the fuel tank assembly, simply rotating the bevel gear set can drive the threaded rod to rotate through the transmission component, causing the cover assembly to move upward and maintain a certain distance from the top of the fuel tank assembly without pulling on the pipes and wiring. The pipes and wiring can be removed first, and then the cover assembly can be removed from the top of the fuel tank assembly.

[0004] The cover of the aforementioned transformer oil tank is a single piece, and the connection structure of the cover is relatively complex. This makes it inconvenient to operate when the cover needs to be inspected or disassembled in the later stages, increasing the need for later maintenance and disassembly.

[0005] Therefore, it is necessary to provide a cover for a transformer oil tank to solve the above-mentioned technical problems. Utility Model Content
