Description
Technical field
The utility model relates to a kind of noise reducing apparatus, specifically a kind of transformer denoising device.
Background technology
Transformer is a kind of common power equipment, and it generally comprises housing and is arranged on iron core, coil and the transformer oil in housing.During transformer work, often produce larger noise because of the vibration of iron core and coil.The noise that transformer produces not only can cause environmental pollution, disturbs and affect the life, working and learning etc. of people; Such as, but also meeting harm humans is healthy, makes people's impaired hearing, headache, dreaminess, failure of memory, affects children's intelligence development etc.Given this, should take measures effectively to reduce the noise that transformer produces.Reduce the noise of iron core generation in prior art by reducing iron core magnetic flux density, but this can increase the cost of transformer greatly, therefore not too economical.
Utility model content
The purpose of this utility model is just to provide a kind of transformer denoising device, and this denoising device effectively can reduce the noise that transformer produces, and cost is low, economical and practical.
The utility model is achieved in that a kind of transformer denoising device, comprising:
Blimp, is arranged on the circumferential periphery of transformer shell;
Holder, in uncovered groove structure, is fixed on the inwall of described blimp bottom it;
Sound-absorbing material, is placed in the inside grooves of described holder;
Cover plate, is fixed on the opening end place of described holder, for carrying out stop location to the sound-absorbing material being positioned at described holder groove;
Base, with the bottom connection of transformer shell, has some grooves in the bottom of described base; And
Spring damper, rabbets in the groove of described base bottom.
The inside grooves of described holder is provided with some dividing plates, and the groove of described holder is divided into some accommodation spaces by described dividing plate.
Described sound-absorbing material is glass fibre or polyurethane foam plastics.
The inwall of described blimp is covered with one deck damping barrier film.
Described damping barrier film is covered with frosted layer.
Rubber blanket is provided with at the end face of described base.
The utility model arranges blimp by the surrounding at transformer shell, at the affixed holder of blimp inwall, holder is uncovered groove structure, sound-absorbing material (such as glass fibre, polyurethane foam plastics or mineral wool etc.) is placed, by arranging cover plate at the open-mouth of holder to position the sound-absorbing material in holder groove in the inside grooves of holder.The noise overwhelming majority sound-absorbing material be fixed in seat spread out of by transformer shell inside absorbed, and effectively prevents noise outwards to propagate.The utility model also arranges base bottom transformer shell, in the groove of base, rabbet spring damper, effectively can be alleviated the vibration of transformer generation, reduce the generation of unnecessary noise by spring damper.
Effectively can reduce by the utility model the noise that transformer produces, greatly reduce the pollution of transformer noise to environment, decrease the harm that noise on human class is healthy, normal work and the life of people can be ensured.And the utility model structure is simple, and easily mount and dismount, cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, transformer shell 1 comprises four side plates of base plate, top board and surrounding.The utility model is that the circumferential periphery of transformer shell 1 is provided with blimp 2, and four of transformer shell 1 side plates are surrounded by blimp 2, forms confined space between blimp 2 inwall and transformer shell 1 four side plate lateral surfaces.
The inwall of blimp 2 is provided with the seat 3 that to be relatively fixed with the side plate of transformer shell 1, and holder 3 is in uncovered groove structure, and the bottom of holder 3 is fixed in the vertical inner wall of blimp 2.The inside grooves of holder 3 is provided with some dividing plates 5, these dividing plates 5 can be arranged in parallel, also can mutually intersect, dividing plate 5 height is suitable with the depth of groove of holder 3, and the groove of holder 3 is divided into the identical or different accommodation space of some shapes by dividing plate 5.Fill sound-absorbing material 4 respectively in each accommodation space in holder 3 groove, sound-absorbing material 4 can be glass fibre, polyurethane foam plastics, mineral wool, suction sand or iron filings etc.The noise spread out of by transformer shell 1 inside can be absorbed effectively by sound-absorbing material 4, thus greatly can reduce the noise that transformer produces.Holder 3 and the respective resonance frequency of dividing plate 5, the frequency produced when should run with transformer has difference, avoids producing resonance and causes larger noise.
In order to position the sound-absorbing material 4 of filling in holder 3 groove, the utility model is provided with cover plate 6 at the opening end place of holder 3.Cover plate 6 is the sheet material allowing noise to pass through, and is connected, also connects by clamping block between cover plate 6 with holder 3 by bolt.Between the side plate of cover plate 6 plate identity distance transformer shell 1, there is certain distance, or weighing-appliance there is certain space.The upper end of holder 3 can connect with the top of blimp 2 inwall, also can reserve certain space; The lower end of holder 3 can with the bottom connection of blimp 2 inwall, also can reserve certain space.
In order to more effectively reduce the noise that transformer shell 1 inside produces, can also adhere to one deck damping barrier film on the inwall of blimp 2, damping barrier film can be made up of macromolecular material, and damping barrier film is adhesively fixed on the inwall of blimp 2 by colloid.Damping barrier film can increase damping, effectively suppresses the vibration of transformer.The utility model can also arrange frosted layer on damping barrier film.Frosted layer can play diffuse reflection effect to sound wave, further absorption of noise.
The utility model is provided with base 7 in the bottom of transformer shell 1, has some grooves in the bottom of base 7, is connected to a spring damper 8 each groove is embedded.The elastic strength coefficient k (i.e. Gini coefficient) of all spring dampers 8 must keep completely the same, with ensure transformer shell 1 by equilibrium of forces, evenly; Self resonance frequency of spring damper 8 will keep certain difference with the frequency produced during transformer self-operating, can not be overlapping with spring damper 8 own frequency and cause and resonate during to guarantee that transformer works, and avoids producing larger noise.
The utility model can also arrange rubber blanket between the bottom of transformer shell 1 and base 7, by the spring damper 8 in rubber blanket and base 7 groove, can realize dual vibration isolation sound insulation, considerably reduce vibration and the solid-borne sound transmission of transformer.
