A kind of band described in the utility model can denoising device transformer, denoising device is located in fuel tank, using more
Hole block of glass wool, it is nearest apart from noise source, noise can be effectively absorbed, and some fiber fines can be avoided in fuel tank
Diffusion, reduces environmental pollution, its advantage is in particular in：
（1）Denoising device is arranged in the interlayer in fuel tank by the utility model, by using cellular glass cotton plate, low coverage
It is liftoff to avoid noise to external diffusion by including noise receives caused by iron core, but because cellular glass cotton plate has good guarantor
Temp effect, it is the cooling for not influenceing transformer oil in fuel tank, cooling tube is additionally provided between adjacent porous block of glass wool,
The cooling tube connects with the radiating tube outside fuel tank shell, the temperature that can be effectively reduced between cellular glass cotton plate, in transformer
A cryosphere is formed around oil, iron core can also be reduced while not influenceing or even the radiating effect of increase transformer oil
Caused noise；
（2）The utility model is provided with shock-absorbing protecting set outside transformer shell, by the high-elastic flexible material of selection, can incite somebody to action
The cut-off that is rigidly connected between metal shell and ground, while 4 heelpieces are provided with the lower section of shock-absorbing protecting set, play certain
Sound-absorbing effect, noise is operatively avoided to be delivered to by housing in ground and air；
（3）The inside and outside wall of the fuel tank of transformer is carried out thickening processing by the utility model, can be played certain noise and be stopped
Effect, while carry out coarse processing to inner wall of oil tank surrounding, is provided with some arc convex on its surface, excessively smooth wall,
The volume of echo increase noise is easily produced, by that sound wave can be made to produce repeatedly refraction internal coarse processing, is effectively subtracted
Weak noise.
