Abstract
The utility model discloses an anti-resonance noise-reducing box type noise-reducing transformer. The anti-resonance noise-reducing box type noise-reducing transformer comprises an oil box, a groove-type container, a noise-reducing box, a sound-proofing plate and a shell connected with the exterior of the oil box. The groove-type container is connected with the exterior of the oil box and is filled with sound-absorbing matters such as glass fibers, fine sand and scrap irons. The noise-reducing box is connected with the shell through a connecting piece. The sound-proofing plate is connected with the shell through a fixing shaft. The noise-reducing box and the sound-proofing plate are parallel and form a cavity. The anti-resonance noise-reducing box type noise-reducing transformer has the advantages that because the groove-type container is filled with the sound-absorbing matters such as the glass fibers, the fine sand and the scrap irons, inherent frequency of a resonance system of the transformer body is improved, and abnormal noise caused by resonance of the oil box and iron cores is avoided; and because the noise-reducing box and the sound-proofing plate are parallel and form the cavity, noise in the noise-reducing box oscillates in the cavity back and forth to consume energy so as to achieve the purpose of reducing the noise.
Description
Technical field
The utility model relates to the electrical network environmental technology field, relates in particular to the box noise reduction transformer of a kind of anti-resonance noise reduction.
Background technology
Along with the development of society, the enhancing of people's environmental consciousness, the customer requirements noise of transformer is more and more littler.In particular for the transformer that the substation in shopping centre and the residential block uses, noise requirements is littler.Noise of transformer is contaminated environment not only, and harm humans is healthy again.Fuel tank is subjected to the influence of iron core alternating magnetic field can cause vibration, if fuel tank and iron core resonance will cause that noise is unusual, for reducing noise, simple by reducing the transformer core magnetic flux density, reduce the noise that produces unshakable in one's determination, will increase the transformer cost greatly, make transformer very uneconomical.
The utility model content
The utility model provide a kind of can the low-cost box noise reduction transformer of anti-resonance noise reduction that reduces noise.
Realize that the technical scheme that above-mentioned purpose is taked is: the box noise reduction transformer of a kind of anti-resonance noise reduction, comprise fuel tank, grooved container, noise reduction case, sound panel and the shell that is connected with the fuel tank outside, described grooved container is connected with fuel tank is outside, sound absorption materials such as filled glass fiber, fine sand, iron filings in the described grooved container, described noise reduction case is connected with shell by connector, described sound panel is connected with shell by fixed axis, the parallel cavity that forms between the two with sound panel of described noise reduction case.
Described noise reduction case comprises cabinet shell, one deck noise reduction unit and connecting rod at least, and described noise reduction unit is connected with cabinet shell by connecting rod, and described cabinet shell is frame type structure product, and is parallel between the described noise reduction unit.
Described noise reduction unit comprises at least one noise reduction rod, and described noise reduction rod equidistantly is parallel in the same plane.
Described noise reduction rod comprises excellent core and foam cover, and described foam cover is coated on excellent core excircle.
The beneficial effects of the utility model are: sound absorption materials such as filled glass fiber, fine sand, iron filings in the grooved container, improved the natural frequency of transformer body resonance system, avoid the resonance of fuel tank and iron core to cause that noise is unusual, thereby sound absorption materials such as glass fibre, fine sand, iron filings can reduce the energy absorption part of fuel tank vibrations noise; The parallel cavity that forms between the two of noise reduction case with sound panel, this cavity forms the low-frequency resonance denoising structure with the noise reduction case, thereby makes noise by the noise reduction case consumed energy that vibrates back and forth in cavity reach the purpose that reduces noise; The noise reduction case is provided with the multilayer noise reduction unit, and the noise reduction rod adopts the excellent core that coats the foam cover, plays the purpose that reduces noise thereby increase reflective surface area.The utility model can effectively reduce noise 8-10 decibel and with low cost, greatly reduces the pollution of depressor noise to environment, has reduced the harm to human body health, has guaranteed normal production of densely populated regional people and life.
