Abstract
The utility model discloses a metal foil winding with tapes which is used for a wound transformer, an inductor and the like. A plurality of parallel high-voltage insulation films are arranged at certain intervals on the surface of metal foil; tapes are arranged on the surfaces of the high-voltage insulation films; and a plurality of strip-shaped parallel insulation tapes are arranged among the plurality of the parallel high-voltage insulation films on the surface of the metal foil and fixedly bonded on the surface of the metal foil. A swelling phenomenon doesn't exist, and subsequent processes such as winding shaping, insulation paint immersing and the like are omitted, and the cost is saved; and almost no air exits among winding layers, the heat-conducting property is good, and the temperature rise is low.
Description
Technical field
The utility model relates to a kind of metal winding structure, is used for coiling transformer, inductance etc.,
Background technology
Conventional transformer or inductance generally use coilings such as metal enamel conductor, metallic conduction row, metal sheet band, metal forming.In order to improve power density and weight reduction, reduce volume, to reduce cost, when transformer or inductance manufacturing, often use metal forming as winding material.Need the liner insulation film during metal forming coiling, and insulation film is because the restriction of technology and cost, thickness is generally all greater than 0.02mm, great majority are greater than 0.04mm, this just causes following problem: the one, and metal forming is more thick, conductive capability is more strong, but proximity effect is with the increase of limited thickness, thickness also can take place increase the situation that mechanical strength also increases sharply, when making coiling square core or supporting square skeleton, the more serious elasticity bulge phenomenon of middle generation, the window size that loss is limited causes inside to have air.The 2nd, metal forming is more thin, conductive capability is more poor, in order to pass through big electric current, must use the multilayer stack and around, and in order to overcome skin effect and proximity effect, must fill up upper nonconductive Film between multilayer, the dielectric film of multilayer causes the valid window loss, and the middle bulge phenomenon that strain causes also can take place.
Summary of the invention
The purpose of this utility model is for the defective that overcomes existing metal winding provides a kind of band glue metal forming winding, can avoid the short circuit phenomenon that distance takes place between the clearance for insulation that produces because of the out-of-flatness of metal forming and dish.
The technical solution adopted in the utility model is: a kind of band glue metal forming winding, keep at a certain distance away on the surface of metal forming and arranged many parallel High-Voltage Insulation films, the High-Voltage Insulation film has glue on the surface, be furnished with many elongated parallel insulating cements on the metal foil surface and between described many parallel High-Voltage Insulation films, and the insulating cement fixed bonding is on metal foil surface.
The beneficial effects of the utility model are:
1, the utility model can omit the winding shaping follow-up, soak technology such as insulating varnish, saves cost.Almost there is not air between winding layers, the winding good heat conductivity, temperature rise is low.
2, the utility model does not have bulge phenomenon, and the window utilance is higher, and under similarity condition, the window of same core can the more windings of coiling or the long-pending winding in heavy in section more.
3, when the coiling transformer, the umber of turn increase can add air gaps and reduce magnetic flux density, so the loss reduction, perhaps reduces the magnetic material size as required, weight reduction, cost.When the coiling inductance, if the constant increase winding of number of turn net sectional area reduces the wastage thereby can reduce D.C. resistance.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Among the figure: 1. metal forming; 2. insulating cement; 3. dielectric film.
Embodiment
On the surface of metal forming 1, keep at a certain distance away and arranged many parallel High-Voltage Insulation films 3, the High-Voltage Insulation film has glue on 3 surfaces.On metal forming 1, between many parallel High-Voltage Insulation films 3, arrange many parallel insulating cements 2 again.Insulating cement 2 is elongated, and insulating cement 2 fixedly is bonded on metal forming 1 surface, and insulating cement 2 is also parallel with High-Voltage Insulation film 3.Metal forming 1 can be selected all kinds of metal materials such as aluminium foil, Copper Foil for use.
When using the single-layer metal paper tinsel as winding, owing on the surface glue is arranged, glue is arranged also on the High-Voltage Insulation film 3, make when coiling, just to be stuck fixingly between each layer of winding, the centre bulge phenomenon can not appear.
When using the multilayer metal foil stack to carry out coiling, glue is all arranged on each layer metal foil surface, by gluing fixing, the centre can not heaved when coiling.Because select the adhesive of insulating properties, as there being voltage difference between the same winding hardly, insulating capacity is still effective, proximity effect can be contained.
