Abstract
The utility model discloses a double-coating enameled wire. From inside to outside, the double-coating enameled wire is provided with a conductor (1), a metal polyester-imide paint film (2) and a polyamide-imide paint film (3) in sequence, wherein the metal polyester-imide paint film (2) is made from complex nano metal oxide particles (4) and is a THEIC modified metal polyester-imide paint film (2); and the conductor (1) is a copper or aluminum wire. The polyester-imide paint film has stronger pulsed voltage resistance and the polyamide-imide paint film is high-temperature-resistant, so that the double-coating enameled wire meets requirements for performance of enameled wires in a GB/T21707 'insulation specification for three-phase asynchronous motors special for variable frequency speed regulation', and can be used on an efficient variable-frequency motor to ensure the safe life of the efficient variable-frequency motor for long-term usage.
Description
Technical field
The utility model relates to a kind of enamelled wire, is specifically related to a kind of pair of coating enamelled wire.
Background technology
Along with the development of society, to the continuous increase of energy demand, tapping a new source of energy and improving efficiency becomes the maximum problem that the mankind face.The electric power of the whole world more than 60% is consumed by motor, therefore improves electric efficiency, will directly reduce mass energy consumption.The main insulation system of high efficiency motor is enamelled wire, and the high efficiency motor operation process can produce high order harmonic component, produces 1-10 overvoltage doubly, seriously reduces the insulation life of enamelled wire.Present solution has: the film thickness that 1, increases enamelled wire, increase film thickness and can improve certain voltage endurance capability, but the increase of thickness affects the tack of paint film, produces the electric machine winding process and is more prone to damage enamelled wire, and the effect that therefore plays is limited; 2, add one deck mica at enamelled wire, the mica pulse voltage plays certain cushioning effect, but the copper factor degradation, the volume of motor strengthens; 3, the inorganic material of in wire enamel, mixing, compatible but the two can not be stablized, mechanical performance descends, and the stretching rear stability is relatively poor.Therefore the enamel insulated wire that uses at present can not satisfy the user demand of energy-saving efficient motor, particularly wind-driven generator, driving motor for electric automobile, roller motor etc., can not guarantee the useful life of motor.
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 two coating enamelled wires of anti-pulse voltage are provided.
Technical scheme: a kind of pair of coating enamelled wire is provided with conductor, metal-polyester imines paint film and polyamidoimide paint film from inside to outside successively.
Conductor in the utility model is copper or aluminium round wire, prime paint is the polyester-imide paint film of match gram modification, wherein contain the nano-metal-oxide particle with chemical bonds, form the paint film with metal oxide, but pulse voltage plays buffering and shielding action; In order further to improve high temperature resistant, wear-resisting, the hydrolysis ability of enamelled wire, the surface layer lacquer is the polyamidoimide paint film.
Beneficial effect: the polyester-imide paint film has stronger anti-pulse voltage performance, the polyamidoimide paint film can be high temperature resistant, therefore, two coating enamelled wires that the utility model provides satisfy among the GB/T21707 " frequency control special three-phase asynchronous motor insulation standard " performance requirement to enamelled wire, can be used on the high-efficiency frequency conversion motor, guarantee the long-term safe life that uses of high-efficiency frequency conversion 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 pair of coating enamelled wire is provided with conductor 1, metal-polyester imines paint film 2 and polyamidoimide paint film 3 from inside to outside successively.
Conductor 1 in the present embodiment is copper round wire, prime paint is the metal-polyester imines paint film 2 of match gram modification, wherein contain the nano-metal-oxide particle 4 with chemical bonds, form the paint film with metal oxide, but pulse voltage plays buffering and shielding action; The surface layer lacquer is polyamidoimide paint film 3, has improved high temperature resistant, wear-resisting, the hydrolysis 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.
