Abstract
The utility model relates to a kind of two coating enamelled wire, forms primarily of wire, metal oxide polyester-imide paint film and metal oxide polyamidoimide paint film.Metal oxide polyester-imide paint film and metal oxide polyamidoimide paint film all add nano metal oxide particle, form superpower withstands corona effect and heatproof chemical-resistance.Therefore, two coating enamelled wire Inverter fed motor life-spans that the utility model provides more than in GB/T21707 " frequency control special three-phase asynchronous motor isolation specifications " to outside the performance requirement of enamelled wire, there is the chemical property that good refrigerant etc. is excellent, guarantee the safe life at automobile frequency converting air-conditioner compressor motor Long-Time Service.
Description
Technical field
The utility model relates to a kind of enamelled wire, is specifically related to a kind of two 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 maximum problem faced by the mankind.Air conditioning for automobiles is automobile important component part, is also that automobilism power consumption runs parts, improves the operational efficiency of air conditioning for automobiles, will effectively reduce the oil consumption of automobile.Improve the efficiency of air conditioning for automobiles, major technique improves the operational efficiency of automobile air conditioner compressor.The machine effect of compressor improves, to main insulation system--enamelled wire proposes requirements at the higher level, originally enamelled wire is polyamidoimide complex polyester imines enamelled wire, the requirement of this structure energy satisfying basic insulation, but frequency control wanted by compressor, improve operational efficiency, enamelled wire must on original insulation system basis, increase withstands corona performance, avoid high frequency spikes voltage to accelerate the aging of insulation.Current solution has: the film thickness 1, increasing enamelled wire, increase film thickness and can improve certain voltage endurance capability, but the increase of thickness affects the tack of paint film, produce electric machine winding process and be more prone to damage enamelled wire, the limited efficiency therefore played; 2, at the additional one deck mica of enamelled wire, mica pulse voltage plays certain cushioning effect, but copper factor degradation, the volume of motor strengthens; 3, to adulterate in wire enamel inorganic material, but the two can not stablize compatible, mechanical performance declines, and stretching rear stability is poor.Therefore the enamel insulated wire used at present can not ensure the useful life of efficient automobile air conditioner compressor motor very well.
Utility model content
Utility model object: the purpose of this utility model is the specific demand of automobile air conditioner compressor, provides a kind of two coating enamelled wires of anti-pulse voltage.
A kind of two coating enamelled wire, is characterized in that: be provided with conductor, metal oxide polyester-imide paint film and metal oxide polyamidoimide paint film from inside to outside successively.
Further, be also provided with metal oxide nano particles, described metal oxide nano particles is dispersed among metal oxide polyester-imide paint film and metal oxide polyamidoimide paint film.
Further, the material of described metal oxide polyester-imide paint film is match gram modification, and the material of described metal oxide polyamidoimide paint film is 220 class F insulation films.
Further, described conductor is copper or aluminium round wire.
The beneficial effects of the utility model are:
Metal oxide polyester-imide paint film and metal oxide polyamidoimide paint film all add nano metal oxide particle, form superpower withstands corona effect and heatproof chemical-resistance.Therefore, two coating enamelled wire Inverter fed motor life-spans that the utility model provides more than in GB/T21707 " frequency control special three-phase asynchronous motor isolation specifications " to outside the performance requirement of enamelled wire, there is the chemical property that good refrigerant etc. is excellent, guarantee the safe life at automobile frequency converting air-conditioner compressor motor Long-Time Service.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device.
Embodiment
Below technical solutions of the utility model are described in detail, but protection range of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of two coating enamelled wire, is provided with conductor 1, metal oxide polyester-imide paint film 2 and metal oxide polyamidoimide paint film 3 from inside to outside successively.
Conductor 1 in the present embodiment is copper round wire, prime paint is the metal oxide polyester-imide paint film 2 of match gram modification, finish paint is metal oxide polyamidoimide paint film 3, wherein contain with the metal oxide nano particles 4 of chemical bonds, form the paint film with metal oxide, pulse voltage can play buffering and shielding action, high temperature resistant, wear-resisting, hydrolysis ability.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
