Abstract
The utility model discloses an aluminum foil coil wound by the aluminum foil, which consists of an aluminum foil layer and a layer insulation paper, wherein the inner and the outer surfaces of the wound aluminum foil coil are provided with insulating materials. The insulating materials wound on the inner and the outer surfaces of the layer insulation paper and the aluminum foil coil are DMD pre-impregnation material; the DMD pre-impregnation material is formed by baking heat-resistant modified epoxy resin dipped by selecting polyester film and polyester fiber non-woven fabric flexible composite material (F grade DMD); and viscidity is generated after pre-baking at a set point of temperature so that the aluminum foil coil is firmly pasted and the integral mechanical strength is improved. The aluminum foil coil has simple structure and reasonable design, and is wound by using the aluminum foil layer and the layer insulation paper, thereby simplifying the process of winding procedure, improving the winding efficiency and being beneficial to reducing the production cost.
Description
Technical field
The utility model relates to a kind of aluminum foil winding by the aluminium foil coiling.
Background technology
In the prior art, transformer coil is made of the silk-covered wire coiling usually, requires silk-covered wire to arrange in order, and turn-to-turn is arranged closely, and every coiling one deck all needs to carry out bound edge and layer insulation is handled, at last to the wrapping of insulating again of the intact coil of coiling.Coiling working (machining) efficiency like this is low, causes production cost to be difficult to reduce.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of aluminum foil winding is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of aluminum foil winding, and described aluminum foil winding is made of aluminium foil layer and the coiling of layer insulation paper, and the surfaces externally and internally of the aluminum foil winding that coiling is intact has all been wrapped up insulating material.
As preferably, the insulating material of described layer insulation paper and the wrapping of aluminum foil winding surfaces externally and internally is the DMD preimpregnation material, the DMD preimpregnation material selects for use polyester film, the heat resistance modified epoxy resin of nonwoven polyester fabric composite flexible material (F level DMD) dipping to cure and form, after through the set point of temperature preliminary drying, self produce viscosity, make aluminum foil winding paste firmly, improved whole mechanical strength.
The utlity model has simple in structurely, reasonable in design, adopt aluminium foil layer and the coiling of layer insulation paper, simplified the technology of coiling operation, improved the coiling working (machining) efficiency, help reducing production costs.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the utility model is made of aluminium foil layer 1 and 2 coilings of layer insulation paper, and the surfaces externally and internally of the aluminum foil winding that coiling is intact has all been wrapped up insulating material.Wherein the insulating material of layer insulation paper and aluminum foil winding surfaces externally and internally wrapping is the DMD preimpregnation material, the DMD preimpregnation material selects for use polyester film, the heat resistance modified epoxy resin of nonwoven polyester fabric composite flexible material (F level DMD) dipping to cure and form, after through the set point of temperature preliminary drying, self produce viscosity, make aluminum foil winding paste firmly, improved whole mechanical strength.The utlity model has simple in structurely, reasonable in design, adopt aluminium foil layer and the coiling of layer insulation paper, simplified the technology of coiling operation, improved the coiling working (machining) efficiency, help reducing production costs.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection range of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
