Embodiment
The present invention can be explained in more detail by the following examples, the invention is not limited in the following examples；
With reference to described in accompanying drawing 1~2 it is a kind of be used for transformer substation in city in transformer denoising device, including cabinet 2, left backplate 5,
Parallels 6, cabinet door 7, bi-level resonant acoustic board 8, right backplate 10 and rear backplate 11, the cabinet 2 is frame structure, in cabinet 2
Upper end is provided with upper guard board, and radiator fan 1 on a plurality of is provided with the upper guard board, and the upper radiator fan 1 passes through line respectively

Be provided with cabinet door 7 previously by hinge, the side of the cabinet door 7 be provided with handle 9, be provided with right backplate 10 on the right side of cabinet 2,
Side radiator fan 3 is respectively equipped with the upper and lower part of the right backplate 10, attacker 4 is provided with the middle and upper part of right backplate 10,
Rear backplate 11 is provided with behind cabinet 2, the middle and upper part of backplate 11 is provided with attacker 4 in the rear, is provided with the bottom of rear backplate 11
A plurality of heat emission holes 12, it is respectively equipped with the medial surface of the upper guard board, left backplate 5, cabinet door 7, right backplate 10 and rear backplate 11
Bi-level resonant acoustic board 8 or spray fiber K13, the bi-level resonant acoustic board 8 are increased on the basis of mono-level resonant acoustic board
One layer of resonance acoustic board of same size is added to form double resonator, the fiber K13 is to utilize pure plant fiber and water base gluing
Agent, which is mixed with, to be formed, and the corner below cabinet 2, which is respectively equipped with parallels 6 and formed, described is used for transformer in transformer substation in city
Denoising device.
At least one hook is provided with above wherein described cabinet 2, when needing to carry out noise reduction to transformer, Ke Yitong
The top that the present apparatus is lifted into transformer by loop wheel machine is crossed, then by present apparatus cover on the transformer；
Further, in order to improve noise reduction, in the medial surface spray fiber K13 of the cabinet 2；
Further, it is provided with observation window in the middle and upper part of cabinet door 7；

It should be noted that resonance sound-absorbing principle is to utilize Helmholtz resonator principle, by occurring with low-frequency sound wave
The acoustic energy of resonance consumption sound wave, i.e., when the frequency of incident acoustic wave is equal to the intrinsic frequency of sound absorption structure, it will resonate,
At this moment the speed of air vibration reaches maximum in neck tube.When incident acoustic wave frequency departure resonant frequency, vibration velocity just correspondingly by
It is decrescence small, due to frictional dissipation acoustic energy Wa and vibration velocity it is square directly proportional, be represented by：Wa=RaU2, necessarily come for acoustic resistance
Say, vibration velocity is bigger, and the acoustic energy of consumption is also bigger, and vibration velocity is maximum during resonance, therefore its acoustic absorptivity is also maximum.The hole of resonant structure
The several factors such as footpath size, distribution mode, arrangement density can have an impact to the acoustically effective of structure.
Double resonance sound absorption is to increase by one layer of resonance material of same size on the basis of mono-level resonant material, is formed double
Resonant cavity, first resonant cavity also serve as the coupling element of two resonators.In experiment, the high frequency performance of double resonance sound-absorbing material is protected
Hold it is constant, on the basis of former absorption coefficient curve, can to low frequency move 2/3~1.5 octave.Therefore have for low frequency noise reduction
Significance.
Wherein fiber K13 is to be mixed with to form with water-based adhesive using pure plant fiber, and it is for Middle and low frequency noise
Acoustic absorptivity is high, pollution-free, but K13 fibers poor heat transfer, cost are high, easy aging, are not easily recycled, and such sound-absorbing material has excellent
Good effect of low-frequency sound absorption, cost is between foam metal and mineral wool, and therefore, the present invention is preferentially absorbed sound from bi-level resonant
Plate 8.
