Abstract
Disclosed is a corona resistant enamelled rectangular copper wire. The inner layer of the corona resistant enamelled rectangular copper wire is a rectangular copper wire conductor, three layers of insulation paint films are coated outside the rectangular copper wire conductor, the first layer is a polyester paint film, the second layer is a corona resistant paint film, the third layer is a polyesterimide or polyimide paint film, the total thickness of the paint films ranges from 0.12mm to 0.17mm, and the thickness of the corona resistant paint film is not larger than 0.05mm. Corona resistant paint is coated outside the rectangular copper wire, and total insulation thickness of the corona resistant enamelled rectangular copper wire can be controlled below 0.17mm on the premise of meeting corona resistant requirements. During usage, the corona resistant enamelled rectangular copper wire can effectively reduce design volume of a motor, has high flexibility, is low in cost, and has extremely strong market value.
Description
Technical field
The utility model relates to a kind of enameling copper strap wire, and this copper strap wire especially is applied to examine latent motor, thermal power generation, wind power generation etc. and requires the exigent environment of anti-corona.
Background technology
At present, the domestic existing enamelling cuprum round line of anti-the corona is used for the winding wire of variable-frequency motor.But for the enameling copper strap wire of anti-the corona, the domestic blank that is in.At present domestic have the motor of requirement to steel mill electric machine, nuclear-powered submarine motor, thermal power generation, wind power generation etc. to anti-corona, all is to adopt the wrapped or sintering copper flat wire of import Du Pont corona-resistant film as winding.Though this winding wire dielectric strength is better, corona-resistance property is also fine.But cost an arm and a leg, and insulation thickness there is significant limitation generally greater than 0.20mm to the design of electrical motor volume, is unfavorable for cost savings.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of have good corona-resistance property, cost performance height, the enameling copper strap wire of anti-corona that practicality is good.
The technical solution of the utility model is: internal layer of the present utility model is the copper strap wire conductor, the copper strap wire conductor is coated with three-layer insulated paint film outward, ground floor is the polyester paint film, the second layer is the paint film of anti-the corona, the 3rd layer is polyester-imide or polyimides paint film, the paint film gross thickness is 0.12～0.17mm, and the film thickness of anti-the corona is not more than 0.05mm.
Further, the THICKNESS CONTROL of anti-corona lacquer is between 0.03-0.05mm.
Further, described anti-corona lacquer is HPH-35A type corona-resistant wire enamel.
The utility model adopts the mode that is coated with to be coated with anti-corona lacquer outside copper strap wire, its thickness is guaranteeing under the prerequisite that anti-corona requires, can be controlled at the total insulation thickness of the enameled sheet wire of anti-the corona below the 0.17mm, in use, can effectively reduce the design volume of motor, have very big flexibility, and cost is low, has very strong market value.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that copper strap wire conductor, 2 is that polyester paint film, 3 is that the paint film of anti-corona the, 4 is polyester-imide or polyimides paint film among the figure.
Embodiment
Embodiment one
Internal layer of the present utility model is a copper strap wire conductor 1, is coated with three-layer insulated paint film outside the copper strap wire conductor 1, and ground floor is a polyester paint film 2, the second layer is the paint film of anti-corona the 3, the 3rd layer is polyester-imide film 4, and the paint film gross thickness is 0.12mm, and the paint film of anti-corona the 3 thickness are 0.03mm; Further, the paint film of anti-corona the 3 of the present utility model is a HPH-35A type corona-resistant wire enamel.
Embodiment two
Internal layer of the present utility model is a copper strap wire conductor 1, is coated with three-layer insulated paint film outside the copper strap wire conductor 1, and ground floor is a polyester paint film 2, the second layer is the paint film of anti-corona the 3, the 3rd layer is polyimides paint film 4, and the paint film gross thickness is 0.17mm, and the paint film of anti-corona the 3 thickness are 0.05mm;
