Background Art

[0002] The oil level indicator mechanism of the external oil horizontal metal corrugated oil storage tank consists of two parts: displacement conversion and oil level display. At present, the displacement conversion of most oil storage tank manufacturers adopts a torsion spring with a metal wire or metal pull belt structure, and the oil level display mechanism adopts a magnetic flap, metal pull belt, pointer oil level gauge or mechanical pointer.

[0003] The existing oil level indicator mechanism has the following shortcomings during use: In the displacement conversion part, the stiffness of the torsion spring will decrease with the increase of use time, and it is easy for the metal wire or metal pull belt to not rebound with the compression of the corrugated core, resulting in a false oil level, which affects the accurate daily maintenance of the substation. In the oil level display structure, the magnetic flap adopts magnetic coupling, and its service life is about ten years, which is difficult to meet the thirty-year service life of the transformer; and the metal pull belt needs to be selected according to the stiffness of the torsion spring, and it should not be too wide, resulting in the scale on it being difficult to observe at a slightly long distance. The mechanical pointer-type scale mark is placed on the maintenance flange of the cylinder end plate, which also has the problem of being difficult to observe. Utility Model Content
