Problems solved by technology

Most of the existing amorphous alloy transformers reduce the noise by reducing the magnetic density of the transformer design, which will greatly increase the cost of the transformer
In addition, sound-absorbing materials are used in the transformer room, and sound-absorbing materials such as porous glass wool, felt, and fiber slag wool are pasted on the wall and ceiling, or made into sound-absorbing bodies and suspended in space. Reduce the interference of noise to people, but the cost is very expensive; in addition, organic fiber materials have poor fire and moisture resistance; the disadvantage of inorganic fiber materials such as slag wool is that the fibers are brittle and easy to break to form dust that escapes and pollute the environment, and the soft structure, the surface protective layer

Abstract

The invention relates to the technical field of transformers, and discloses an amorphous alloy oil-immersed transformer oil tank with a noise reduction function. The amorphous alloy oil-immersed transformer oil tank comprises a transformer oil tank (17), wherein a shock absorption pad is arranged between the transformer oil tank (17) and a base (15); a first clamping piece (9) is arranged in the transformer oil tank (17); the first clamping piece (9) is horizontally distributed; two first reinforcing ribs (22) are arranged on the first clamping piece (9); a second reinforcing rib (21) is arranged between the two first reinforcing ribs (22); an H-shaped structure is formed by the two first reinforcing ribs (22) and the second reinforcing rib (21); two third reinforcing ribs (23) are arranged on the side wall of the transformer oil tank (17) along the vertical direction; a fourth reinforcing rib (24) is arranged between the two third reinforcing ribs (23); an H-shaped structure is formed by the two third reinforcing ribs (23) and the fourth reinforcing rib (24). According to the amorphous alloy oil-immersed transformer oil tank disclosed by the invention, through the H-shaped structures formed by the first clamping piece and the side wall of the transformer oil tank, the noise of a transformer is reduced under the situation that the magnetic density is not changed, and the problem in the prior art that the noise of the transformer is large is solved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an amorphous alloy oil-immersed transformer oil tank with a noise reduction function. Background technique [0002] At present, power users at home and abroad are affected by the pressure of energy saving and emission reduction, and amorphous alloy transformers are more and more concerned and used by people. Although the amorphous alloy transformer has the advantage of very low no-load loss, due to its sensitivity to stress, the amorphous alloy core cannot be fixed with clamps, and the noise caused by hysteresis stretching is inevitable. The noise nuisance problem of amorphous alloy transformers has always been the primary factor hindering the promotion and application of amorphous alloy transformers. [0003] The noise of the amorphous alloy oil-immersed transformers currently produced mainly comes from the vibration caused by the hysteresis of the amorphous core. In addit...
