多层叠绕大截面线圈制作及多种线圈交替换向嵌线工艺优化

Process Optimization of the Production of Multi-Layer Stacking Coil with Large Section and the Alternative Reversal Inserting of Multiple Coils

针对高功率密度鼠笼式异步风力发电机(FYS02)采用不同叠绕结构的大截面线圈交替换向嵌线的工艺难点,进行了定子线圈制作和嵌线工艺的系统分析及优化。通过分步绕线、单边线圈鼻部绝缘补强、涨型设备程序调整、线圈绝缘结构优化及嵌线定位优化等工艺的创新,解决了样机制作中的难题,顺利完成产品的批量生产,确保了新型结构风电产品从研发理念到产品产出的顺利过渡,为风电产业的海外发展奠定了技术基础。

To solve the technological difficulties of squirrel cage asynchronous wind generator(FYS02)with high power density,whose stator uses different multi-layer and large section coils and alternative reversal inserting,systematic analysis and optimization of coil production and inserting are implemented.Problems in prototype trial production are settled by innovations of step-by-step winding,insulation reinforcement of single coil nose,adjustment of expansion equipment program,optimization of coil insulation structure,and optimization of the inserting positioning,which make it possible to successfully complete the mass production.This is an important transition of new structure wind power products from research and development concept to actual output,which establishes a technical foundation for the overseas development of wind power industry.
