Anti-corona special enameled wire for wind power generation and production method

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...

Problems solved by technology

Since enameled wires for wind turbines are mainly suitable for wind power generation equipment exposed to oil pollution, seawater corrosion, high temperature and salt, and high altitudes, wind turbines have special requirements for their insulation systems and related insulation materials, while conventional enameled wires are generally There are disadvantages such as poor adhesion, poor flexibility, low breakdown voltage, and poor anti-corona performance.
