Example Embodiment

[0013] The present invention will be further described below in conjunction with the drawings and embodiments, but it is not a basis for limiting the present invention.

[0014] Examples. Anti-corona special enameled wire for wind power generation, composed as figure 1 As shown, it includes a round copper wire 1. The surface of the round copper wire 1 is successively provided with a polyester imine paint layer 2, a corona-resistant paint layer 3, and a polyamide-imide paint layer from inside to outside. Thickness of paint layer 2: thickness of corona-resistant paint layer 3: thickness of polyamide-imide paint layer=4:4:2.

[0015] The total thickness of the polyester-imine paint layer 2, the corona-resistant paint layer 3 and the polyamide-imide paint layer is 0.067mm-0.072mm.

[0016] According to the aforementioned production method of anti-corona special enameled wire for wind power generation, it is characterized in that: the copper round wire is annealed, and then three kinds ...

Abstract

The invention discloses a 200-level anti-pulse voltage composite enameled wire which comprises round copper wires (2). The surfaces of the round copper wires (2) are provided with a variable frequency paint layer (3) and a polyamide imide paint layer (1) in sequence from inside to outside, wherein the variable frequency paint layer (3) includes eight polyester imide paint layers, and the thickness of each polyester imide paint layer is 0.005 [mu]m. The 200-level anti-pulse voltage composite enameled wire in the invention has good corona-resistant performance, thereby prolonging the service life of a variable frequency motor.

Description

technical field [0001] The invention relates to an enamelled round copper wire for a wind power generator and a production method thereof, in particular to an anti-corona special enameled wire for wind power generation and a production method thereof. Background technique [0002] With the increasing scarcity of world energy and the rapid development of science and technology, coupled with people's requirements for environmental protection, people are trying to find a renewable, environmentally friendly and clean green energy that can replace oil, natural gas and other energy. [0003] Wind energy is currently the most promising new type of energy. It is an inexhaustible energy source and a clean, pollution-free, renewable green energy source. The use of wind energy, from windmills to wind power, is a testament to civilization and scientific progress. [0004] The wind generator is the most important part of the wind generator set. For the long-term, stable, safe and reliab...
