Description
Technical field
The utility model relates to a kind of motor component, relates to the wrapped copper strap wire of a kind of variable-frequency motor specifically.
Technical background
Variable-frequency motor is the direction of giving priority to of electromechanics trade, will account for the 50-70% of motor product soon.This also is a significant innovation to the electromagnetic wire industry, and along with the application of high-tension electric motor, high-speed railway traction electric machine, large-scale alternating-current variable frequency motor develops rapidly, general polyimide film lapped wire can not satisfy the variable-frequency motor needs.U.S. Dupont company developed a kind of novel polyimide film of anti-corona the (Kapton CR) that superior heat conduction, heat resistance, mechanical performance, resistant to partial discharges are arranged in 1994.Because the mechanical strength of thin dielectric film is relatively poor, when the coiling winding, fragile thin layer, thus influence the insulation property of electromagnetic wire.
In order to overcome this shortcoming; developed glass fiber bag thin film wire afterwards again; promptly wrapped again one deck glass fiber is used for the protective film layer outside thin layer; to improve the mechanical performance of electromagnetic wire; simultaneously also improved the moisture resistance energy and the heat resistance of electromagnetic wire, and improved accommodation greatly motor windings technology.But the corona-resistant film cost in this structure is higher, has limited its application.Therefore necessary this is improved.
The utility model content
The purpose of this utility model is at the deficiency of existing variable-frequency motor with wrapped copper strap wire, and a kind of new glass fiber bag enameled sheet wire of anti-the corona is provided, and this glass fiber bag enameled sheet wire of anti-the corona has the mechanical strength height, and the characteristics of making easily.
The purpose of this utility model is achieved through the following technical solutions, a kind of glass fiber bag enameled sheet wire of anti-the corona, the center of enameled sheet wire is flat type copper core, outside flat type copper core, be coated with one deck polyester layer of anti-the corona, the polyester layer of anti-the corona is coated with one deck polyester-imide of anti-corona layer again, the polyester-imide of anti-corona layer is coated with one deck polyamidoimide layer outward again, is surrounded with ferry glass insulation lacquer type organic coating mixed layer at polyamidoimide layer outermost.
The utility model advantage:
The utility model has further improved the anti-corona ability of the glass fiber bag enameled sheet wire of anti-the corona by three layers of different insulating barrier, and make than existing thin layer outward wrapped again one deck glass fiber to be used for the method for protective film layer more simple.The mechanical strength height of formed insulating barrier, when the coiling winding, not fragile thin layer, thus greatly improved the insulation property of electromagnetic wire.
Description of drawings:
Fig. 1 is the structural representation of the utility model glass fiber bag enameled sheet wire of anti-the corona.
