Description

Oil-immersed power transformer radiating fin sealing flange structure

Technical Field

The utility model relates to a power grid safety device technical field especially relates to oil-immersed power transformer fin sealing flange structure.

Background

The radiating fins of the oil-immersed power transformer are important components of the oil-immersed power transformer, and have the main function of timely dissipating heat generated by eddy current loss in an iron core of the transformer and load current flowing through a winding of the transformer so as to prevent the performance of the transformer from being influenced by overhigh temperature. In order to achieve a good heat dissipation effect, the oil-immersed power transformer radiating fin is generally made of a thin high-quality cold-rolled steel sheet (ST 13), and is very susceptible to oxidation and corrosion during maintenance, transportation and storage due to the thin thickness. In order to avoid the long-time contact of the inner wall of the radiating fin of the oil-immersed power transformer with humid air in the processes of maintenance, transportation and storage, anticorrosion measures are taken for the radiating fin at the first time after the radiating fin is disassembled. The common anticorrosion measures are sealing and vacuum treatment, and adding inert gas nitrogen to prevent the inner wall of the oil-immersed power transformer radiating fin from contacting air for a long time and slow down the corrosion speed of the inner wall.
