Abstract
The invention discloses a mica tape covered film clad flat copper wire and processing technology thereof, and relates to a stator winding wire suitable for a high-capacity wind driven generator. The inner layer of the flat copper wire is a flat copper wire conductor, the outer layer of the flat copper wire is a mica tape covering layer, and a polyimide fluorine 46 film cladding layer is arranged between the inner layer and the outer layer. The invention has the advantages that: the flat copper wire has high waterproof performance, can be used as a winding wire in humid environment such as wind power generation environment and the like, has prominent waterproof insulation performance, and can keep the original insulating strength after being soaked in 90 DEG C water for eight days through inspection, so that the service life of the flat copper wire is greatly prolonged, wind power generation cost is reduced, and the flat copper wire has a great market prospect.
Description
Technical field
The present invention relates to a kind of mica tape lapped wire and processing technology thereof, relate in particular to a kind of stator winding line and processing technology thereof that is applicable to big capacity wind-driven generator, relate to wrapped film deposited copper flat wire of a kind of mica tape and processing technology thereof specifically.
Background technology
The stator winding line that is used for wind-driven generator is because the particularity of its environment, require it to have good comprehensive performances, the winding wire that is used for this respect now is generally wrapped polyimide film layer or laminated polyester film outside copper strap wire, again at its peripheral hardware mica tape lapping layer, this kind winding wire has good high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability, but water resistance is relatively poor, its dielectric strength of immersion back greatly reduces, and the employed area of wind-driven generator is generally moist, water inlet easily, if the event water resistance is bad for influencing the useful life of winding wire greatly, also can have influence on power generating quality and the efficient and the cost etc. of wind-driven generator.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of water resistance good and have the wrapped film deposited copper flat wire of mica tape and the processing technology thereof of other electric property concurrently.
Technical scheme of the present invention is: its internal layer of the present invention is the copper strap wire conductor, and skin is the mica tape lapping layer, is provided with polyimides fluorine 46 thin layers between internal layer and the skin,
Further in order to make the present invention have excellent mechanical intensity, the present invention is provided with strengthening course between mica tape lapping layer and polyimides fluorine 46 thin layers, and strengthening course can be polyimide film layer or laminated polyester film.
Further mica tape lapping layer peripheral hardware glass fiber covering has further improved its mechanical performance and electric property.
Production technology of the present invention is: push the copper strap wire conductor earlier; Outer wrapped polyimides fluorine 46 thin layers of copper strap wire conductor, wrapped mode is partly overlapping wrapped; Under 400-420 ℃ the condition polyimides fluorine 46 thin layers are being deposited on the copper strap wire conductor again; Wrapped mica tape lapping layer forms behind the natural cooling.
The mica tape lapping layer is for adding the mica tape lapping layer of supporting material, and supporting material can be polyimides or polyester; The outer dipping lacquer layer glass silk covering of mica tape lapping layer according to actual needs at last, the oven dry back becomes line then.
Advantage of the present invention is: have favorable waterproof property, can adapt to the use of the winding wire in the wet environments such as wind power generation, waterproof insulation performance of the present invention is outstanding, through check, can in 90 ℃ of water, soak 8 days, keep original dielectric strength, improve its useful life greatly, reduce the cost of electricity-generating of wind power generation, had great market prospects.
