Abstract
The utility model discloses a composite enameled wire. The composite enameled wire is characterized by comprising a conductor, a polyester-imide paint film and a polyamide-imide paint film from inside to outside, wherein the polyester-imide paint film is a THEIC modified polyester-imide paint film, and the conductor is a copper or aluminum round wire. The composite enameled wire is simple in structure, low in cost and simple in manufacturing process and has good high-temperature resistance, and the temperature grade of the paint film can reach 220, so that heat ageing of motor insulating parts is prevented, and the safe life for long-term usage of an efficient energy-saving motor is ensured.
Description
Technical field
The utility model relates to a kind of enamelled wire, is specifically related to a kind of composite enameled wire.
Background technology
High efficiency motor because of when running temperature raise paint film insulating material accelerated ageing under the long term high temperature, the useful life of seriously reducing enamelled wire.At present want solution to have: 1, increase the film thickness of enamelled wire, increase film thickness and can cross and improve certain withstand voltagely, but the increase of thickness affect the tack of paint film, produce the electric machine winding process and be more prone to damage enamelled wire, so the effect that plays is limited; 2, be that 220 grades polyimide varnish substitutes present polyester-imide composite polyamide acid imide paint film structure with temperature grade, but the polyimide varnish cost is too high, general energy-saving efficient motor manufacturer can't accept.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of resistant to elevated temperatures composite enameled wire is provided.
Technical scheme: a kind of composite enameled wire is provided with conductor, polyester-imide paint film and polyamidoimide paint film from inside to outside successively.
Conductor in the utility model is copper or aluminium round wire, and prime paint is the polyester-imide paint film of match gram modification, and adhesion property is good, and the surface layer lacquer is the polyamidoimide paint film, and the composite construction of two-layer paint film makes enamelled wire have good resistance to elevated temperatures.
Beneficial effect: the utility model is simple in structure, and cost is low, and manufacture craft is simple, has good resistance to elevated temperatures, and the temperature grade of paint film can reach 220 grades, prevents the heat ageing phenomenon of motor insulation member, guarantees the long-term safe life that uses of energy-saving efficient motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The below is elaborated to technical solutions of the utility model, but protection range of the present utility model is not limited to described embodiment.
Embodiment:As shown in Figure 1, a kind of composite enameled wire is provided with conductor 1, polyester-imide paint film 2 and polyamidoimide paint film 3 from inside to outside successively.
Conductor 1 in the present embodiment is copper round wire, and prime paint is the polyester-imide paint film 2 of match gram modification, and adhesion property is good; The surface layer lacquer is polyamidoimide paint film 3, has guaranteed the heat-resisting ability of enamelled wire.
As mentioned above, although the specific preferred embodiment of reference has represented and has explained the utility model that it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
Claims (3)
1. a composite enameled wire is characterized in that: be provided with successively from inside to outside conductor, polyester-imide paint film and polyamidoimide paint film.
2. composite enameled wire according to claim 1 is characterized in that: described polyester-imide paint film is the polyester-imide paint film of match gram modification.
3. composite enameled wire according to claim 1, it is characterized in that: described conductor is copper or aluminium round wire.
