Abstract
Sound deadening foil is composed of a polyester film (or polyimide film) layer, a glass fiber felted layer and a glass fiber grid cloth layer, wherein one surface of the glass fiber felted layer is bonded on one surface of the polyester film (or polyimide film) layer, and the glass fiber grid cloth layer is bonded on the other surface of the glass fiber felted layer. The sound deadening foil has the advantages of high-temperature resistance, easy manufacturing, low price and strong practicability; furthermore, when in use, the sound deadening foil can be arranged between a low-voltage coil and an iron core of a transformer for shielding sound field and absorbing sound, the noise-reducing and sound-deadening effects are good, the loss of the transformer is reduced, the service life is prolonged, and the manufacturing cost of the transformer is lowered.
Description
Technical field
The utility model belongs to the parts in the transformer, relates to a kind of noise reduction paper tinsel.This noise reduction paper tinsel is specially adapted to be arranged between low voltage winding in transformers and the iron core, as a kind of quieter material that receives sound, shielding sound field.
Background technology
In the prior art, between the low-voltage coil and iron core of transformer, owing to generally be not provided with quieter material, noise is big during transformer work; The amorphous alloy strips of the employing costliness that has reduces noise, and volume of transformer increase, transformer cost are remained high, and practicality is relatively poor.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned deficiency of the prior art, and a kind of noise reduction paper tinsel simple in structure is provided, and this noise reduction paper tinsel is arranged between low voltage winding in transformers and the iron core especially, can effectively receive sound, noise reduction, sound insulation.
Content of the present utility model is: a kind of noise reduction paper tinsel is characterized in that: be made up of the fiberglass gridding cloth layer (3) that laminated polyester film or polyimide film layer (1), one side are bonded in the glass fibre cotton carpet veneer (2) of laminated polyester film or polyimide film layer (1) one side and are bonded in glass fibre cotton carpet veneer (2) another side.
In the content of the present utility model:
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopts the utility model, the noise reduction paper tinsel is arranged between low voltage winding in transformers and the iron core, be used for shielding sound field, receive sound, full-frequency sound absorption, pollution-free, noise reduction, defening effect are good, can reduce transformer loss, increase the service life, save greatly transformer manufacturing cost, improve the Transformer Economic benefit;
(2) adopt the utility model, simple, the making easily of product processes, cheap, high temperature resistant, easy to use, practical.
Description of drawings
Fig. 1 is the utility model embodiment master TV structure schematic diagram;
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Among the figure: 1-laminated polyester film or polyimide film layer, 2-glass fibre cotton carpet veneer, 3-fiberglass gridding cloth layer.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of noise reduction paper tinsel is made up of the fiberglass gridding cloth layer 3 that laminated polyester film or polyimide film layer 1, one side are bonded in the glass fibre cotton carpet veneer 2 of laminated polyester film or polyimide film layer 1 one side and are bonded in glass fibre cotton carpet veneer 2 another sides;
The polyester film of described laminated polyester film 1 is preferably the electric insulation polyester film, 155 ℃ of heatproof indexes; The manufacturing enterprise of polyester film has and reaches magnificent film Co., Ltd of film Co., Ltd, Changzhou Electrical Insulation Works Co., Ltd., Tianjin ten thousand etc. in the Nanjing; The polyimide film of described polyimide film layer 1 is preferably the electric insulation polyimide film, 180 ℃ of heatproof indexes; There are Yabao Insulation Material Co., Ltd., Jiangsu, Yangzhou insulating material company of inferior nation etc. in the manufacturing enterprise of polyimide film;
The bonding agent of described bonding use can be polyurethane first and second adhesive, be preferably F level polyurethane adhesive glue (mixed liquor of two components of polyurethane first, second and acetone solvent); There are Jintan City Adhesive Factory, the new photoinitiator chemical Co., Ltd., Factory in sea, adhesive Co., Ltd of Jintan Xinhua etc. in the manufacturing enterprise of polyurethane first and second adhesive (101 first, component B stick);
The glass fibre cotton felt of described raw material glass fibre cotton carpet veneer 2 and the fiberglass gridding cloth of fiberglass gridding cloth layer 3 are the commercially available prod.
The production method of this embodiment noise reduction paper tinsel can be: after the polyester film impregnation, cure through 70-85 ℃, paste the cotton felt of layer of glass again, the rolling moulding, solidify through curing oven, after the curing, with after the fiberglass gridding impregnation, paste compound good polyester film and glass fibre cotton felt, the rolling moulding again, send into curing oven at last and cure (75 ± 5 ℃ of oven temperatures), after curing 24 hours, cooled off 30 minutes, after the products solidifying moulding, promptly make finished product, can carry out an acceptance inspection then, pack, case.
Polyester film thickness is 0.20--0.25mm, and glass fibre cotton felt thickness is 3.0mm--6.0mm, and fiberglass gridding cloth thickness is 0.04--0.06mm, and product thickness is 3.0--6.5mm.Material is easily purchased, and production technology is simple.
The present embodiment product places between transformer core and the low-voltage coil when using, and is used for receiving sound, shielding sound field, and is respond well.
The utility model is not limited to the foregoing description, and the utility model content is described all can implement and have described good result.
