Abstract
The utility model discloses a low-noise transformer, which comprises a tank wall. A tank rim is arranged on the upper portion of the tank wall, and tank bottom supports are installed at the bottom of the tank wall. The low-noise transformer is characterized in that groove-shaped reinforcing irons are fixed on the outer surface of the tank wall, and vibration attenuation particles are filled in the groove-shaped reinforcing irons. According to the low-noise transformer, the dry and compact vibration attenuation particles are filled in the groove-shaped reinforcing irons disposed on the outer surface of a transformer oil tank, so that the rigidity of the transformer oil tank is improved, better vibration attenuation effect is achieved, noises of the transformer are decreased, and few costs are increased.
Description
Technical field
The utility model relates to a kind of transformer.
Background technology
At present, the Application of Large power transformer more and more in dwelling house and public arena, noise of transformer has become the important technology parameter of transformer.Transformer is synthetic by two parts noise to the noise of emission all around through air, and a part is this bulk noise that produces owing to the tank wall vibration; Another part is because the cooling device noise that cooling fan and oil pump vibration produce.Reduce the method for this bulk noise of transformer; Can control through the ability of dispersing that reduces vibration unshakable in one's determination and reduction noise; On the one hand, the technical measures of taking for iron core have: select the little high-quality silicon steel sheet of magnetostriction amount for use, reduce magnetic flux density unshakable in one's determination, increase seam unshakable in one's determination, increase iron yoke area etc.On the other hand, the technical measures of taking for fuel tank have: increase tank wall intensity, vibration isolator is set between fuel tank bottom and basis, increases the fuel tank damping, at inner wall of oil tank rubber slab etc. is set.But these methods all must increase the material cost and the manufacturing cost of transformer.
The utility model content
The purpose of the utility model provides a kind of lower-cost low noise level transformer.
To achieve these goals, adopt following technical scheme: a kind of low-noise level transformer comprises tank wall; The tank wall top is equipped with the case edge; The tank wall bottom is equipped with the case lower supporter, it is characterized in that: said tank wall outer surface is fixed with flute profile and strengthens iron, and flute profile is strengthened being filled with the vibration damping particle in the iron.
This bulk noise of transformer is mainly derived from the sound that electromagnetic wave vibration unshakable in one's determination is sent, and the noise that iron core sends is outwards propagated through fuel tank, between transformer core and the fuel tank rigid connection is arranged, and vibration unshakable in one's determination is directly passed on the fuel tank.The utility model is through strengthening filling in the iron vibration damping particle dry, consolidation to the flute profile that is arranged on the oil tank of transformer outer surface; Increased the rigidity of oil tank of transformer; Can play the effect of vibration damping better, reach the effect that reduces noise of transformer, and cost increases few.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure, part 1 is a tank wall, and part 2 is strengthened iron for flute profile, and part 3 is thin river sand, and part 4 is the case edge, and part 5 is the case lower supporter.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As depicted in figs. 1 and 2, a kind of low-noise level transformer comprises tank wall 1, case is installed along 4 on the tank wall 1, and tank wall 1 bottom is equipped with case lower supporter 5, and the tank wall 1 outer surface flute profile that has been welded is strengthened iron 2, in flute profile is strengthened iron 2, is filled with the thin river sand 3 of drying, consolidation.
