Description
Technical field
The utility model belongs to magnetic elements technical field, more particularly, to a kind of transformer of new winding.
Background technology
Transformer is to reach safety required distance, it is necessary to increase barricade or use at winding two ends in usual magnetic elements
Three layer insulation wire carrys out coiling, and winding space can be reduced by increasing barricade, reduce utilization rate；Using three layer insulation wire coiling again by line
Material is limited in itself, and the three layer insulation wire of single strand of copper wire is only applicable wattage transformer, and the three layer insulation wire of multiply enamel covered wire
Because the particularity and price of technique are high.
Utility model content
To solve the above problems, one embodiment of the present utility model provide a kind of transformer, including primary coil and
Secondary coil, the primary coil includes the first dielectric film, and the first dielectric film winding is wrapped on the outside of the primary coil；
The secondary coil includes the second dielectric film, and the second dielectric film winding is wrapped on the outside of the secondary coil；Described first
The width of dielectric film winding lap is more than 1/2nd of the first dielectric film width, and second velum winding weight
The width of folded part is more than 1/2nd of the second dielectric film width.
Above-mentioned transformer, the primary coil and the secondary coil are stranded strand copper wire, first dielectric film
The outside for being wrapped in the primary coil of two superimposed, the second dielectric film two superimposed is wrapped in the secondary coil
Outside.
Above-mentioned transformer, the primary coil and the secondary coil are single strand of copper wire, three layers of first dielectric film
The overlapping outside for being wrapped in the primary coil, three layers of second dielectric film it is overlapping be wrapped in the outer of the secondary coil
Side.
Above-mentioned transformer, the strand copper wire is multiply enamel covered wire.
Above-mentioned transformer, the dielectric film is polyimide film, Kapton Tape or poly tetrafluoroethylene.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1) winding space utilization rate can be increased using the stranded multiply enamel covered wire of coating, is selecting same specification magnetic core condition
Under, the sectional area from coiling can be increased, so as to reduce temperature rise raising efficiency.
2) barricade cost and bag barricade man-hour can be reduced using the stranded multiply enamel covered wire of coating and reduces first, level line
The number of plies of interlayer adhesive tape between circle.
3) while using common stranded multiply enamel covered wire, a large amount of combinations being completed according to product demand, reduces and makes work
Phase.
4) in addition, using single strand of copper wire three layer insulation wire because overcurrent sectional area it is too small, it is impossible in high-power transformer
It is upper to be applicable, even if multiply and around can also waste a large amount of winding spaces because of insulating barrier.

Embodiment
Fig. 1 is the schematic diagram according to the transformer coil in the embodiment of the utility model one.Fig. 2 is according to the utility model
The profile of transformer coil in one embodiment.Fig. 1-Fig. 2 is refer to, is implemented in the application one, transformer includes primary line
The winding of circle 1 and secondary coil 1, wherein dielectric film 2 is wrapped in the outside of primary coil 1, and the winding of dielectric film 2 is wrapped in secondary coil
On the outside of (not illustrated in figure).The width of the winding lap of dielectric film 2 is more than 1/2nd of dielectric film width L.
When winding primary coil 1 and secondary coil using dielectric film 2, two adjacent circle dielectric films 2 can produce overlapping
Part.Now so that the width of lap is more than the half of dielectric film width itself, you can reach safety requirement.But simultaneously
Not only it is limited to adjacent two circle overlapping, can be using adjacent three layers even more multiple-layer overlapped in another embodiment of the application
Wind parcel mode.But it is no matter several layers of overlapping, the width of lap is all higher than the half of dielectric film width itself.
In one embodiment, as one kind selection, coil 1 is stranded strand copper wire, and the winding of the two superimposed of dielectric film 2
In the outside of coil 1.Now most preferred embodiment is two superimposed winding on the outside of stranded strand copper wire.And in the present embodiment, it is many
Stock copper cash is multiply enamel covered wire, but is not limited thereto, and other can solve the problem that technology to be solved of the present utility model is asked
Any of coil method of topic belongs to the protection domain of the application.
In one embodiment, as one kind selection, coil 1 is single strand of copper wire, and 2 three layers of overlapping winding of dielectric film are online
The outside of circle 1.
In the embodiment above, the material of dielectric film 2 is polyimide film, Kapton Tape or poly tetrafluoroethylene.
But it is not limited thereto, other can solve the problem that any of insulation membrane material of technical problem to be solved of the present utility model
Material belongs to the protection domain of the application.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1) winding space utilization rate can be increased using the stranded multiply enamel covered wire of coating, is selecting same specification magnetic core condition
Under, the sectional area from coiling can be increased, so as to reduce temperature rise raising efficiency.
2) barricade cost and bag barricade man-hour can be reduced using the stranded multiply enamel covered wire of coating and reduces first, level line
The number of plies of interlayer adhesive tape between circle.
3) while using common stranded multiply enamel covered wire, a large amount of combinations being completed according to product demand, reduces and makes work
Phase.
4) in addition, using single strand of copper wire three layer insulation wire because overcurrent sectional area it is too small, it is impossible in high-power transformer
It is upper to be applicable, even if multiply and around can also waste a large amount of winding spaces because of insulating barrier.
