Abstract
The utility model discloses a direct welding type rectangular high-frequency litz wire and relates to the technical field of production of wires and cables. The direct welding type rectangular high-frequency litz wire comprises two winding wires which are arranged in parallel and have square sections respectively, and a total insulating layer is arranged outside the two winding wires. The direct welding type rectangular high-frequency litz wire is good in bending softness, easy to form, small in winding volume, light in weight and convenient to transport, disassemble and assemble, and the product can finally bear ultrahigh pressure, does not affect the outside and is also free of external interference. The direct welding type rectangular high-frequency litz wire can be suitable for special environments and conditions with large-scale wind power, and is particularly suitable for the winding wires of wind power motors above 1Mw.
Description
Technical field
The utility model relates to the electric wire production technical field.
Background technology
Wind power generation has been obtained significant progress in recent years, but most of producer is main to do small wind-driven generator, and electromagnetic wire also mainly uses sintering line and mica tape envelope curve.Because sintering line and mica tape envelope curve all be single thick conductor, the flexibility of product is poor, the coiling volume is big, needs occupation space many during installation, also is prone to destructiveness such as fracture and damages.
Summary of the invention
The utility model purpose is to design good directly weldering type of the durable type rectangle high frequency litz wire of a kind of crooked pliability.
The utility model comprises that two that be arranged in parallel, sections are respectively square winding wire; Outside said two winding wires, total insulating barrier is set; It is characterized in that each winding wire is provided with the laminated film of anti-the corona respectively, in the said laminated film of anti-the corona, polyimide film is set, at least nine strands of mutual stranded enamelled wires are set in said polyimide film; Per share enamelled wire is made up of mutual at least four stranded single lines, and every single line is made up of the copper wire insulating varnish outer with being wrapped in copper wire.
The crooked pliability of the utility model is good, is easy to moulding, and the coiling volume is little; In light weight, convenient transportation and dismounting are when making product finally self bear superhigh pressure; There is not influence to external world; Again can be by external interference, the utility model can adapt to the particular surroundings and the condition of large-scale wind electricity, is particularly suitable for the winding wire of the above wind power motor of 1 megawatt.On probation through 3 megawatts and above large-scale wind electricity, the utility model product can adapt to the particular surroundings and the condition of large-scale wind electricity fully, and long service life.
Concrete characteristics are following:
1, reduce kelvin effect and approach effect: the common electrical magnet-wire is maximum to carry 6 Ampere currents, otherwise temperature rise is too high, causes resistance heating, produces power loss, and long-time the use causes transformer, reactor, generating equipment burnout phenomenon.The utility model has reduced eddy current field, has reduced electric current kelvin effect and approach effect, makes the interior current capacity of unit are improve 20 times.
When 2, the common electrical magnet-wire moves in high frequency magnetic field, the high-frequency current of generation make output electric current or swinging of signal and influence magnetic flux distributions.The utility model more can adapt to high frequency magnetic field to be changed, and output frequency is stable.
3, because the magnet of the utility model coiling is little more a lot of than the magnet that common electrical magnet-wire forms, so the magnetic field of generation is more concentrated, field intensity is stronger, the electromagnetism conversion ratio is higher.
4, the utility model product power is big, and volume is little, has superpower proof voltage ability.
5, the utility model product has reduced eddy current loss under high-power service condition, has improved the utilance of material greatly, has practiced thrift valuable resource.
6, the utility model product self forms high voltage electric field, but does not influence external environment.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, that directly weldering type rectangle high frequency litz wire is arranged in parallel by two, section is respectively square winding wire 1, and the insulating barrier 8 that is arranged on outside two winding wires 1 is formed.
Each winding wire 1 is provided with the laminated film of anti-corona the 2 respectively; Polyimide film 3 is set in the laminated film of anti-corona the 2; Nine strands of mutual stranded enamelled wires 4 are set in polyimide film 3; Per share enamelled wire 4 is made up of mutual four stranded single lines 5, and every single line 5 is made up of copper wire 6 and the insulating varnish 7 that are wrapped in outside the copper wire 6.
