摘　　要：分析了风力发电机的运行环境对绝缘系统及其材料的特殊要求,开展了1.5 MW直驱式风力发电机绝缘系统及其材料的研究,研制了适合1.5 MW直驱式风力发电机定子绝缘系统要求的聚酯亚胺无溶剂浸渍树脂。对不同浸渍树脂和电磁线组成的风力发电机绝缘系统进行了模拟线棒性能试验,探讨了绝缘系统的耐盐雾性、耐高低温湿热交替性能、介质损耗因数及击穿电压等性能。试验结果表明,由聚酯亚胺无溶剂浸渍树脂、聚酯薄膜粉云母带与聚酰亚胺薄膜熔融绕包电磁线组成的风力发电机绝缘系统具有较低的介质损耗因数、良好的耐盐雾性和高低温绝缘性能,是目前风力发电机绝缘系统性能最优异的绝缘系统之一。Special requirements of wind turbine running environment on insulation system and materials were analyzed and polyester-imide solvent impregnated resin suited for the insulation system of wind turbines were studied. Tests for performance simulation of bars were carried out on wind turbine insulation system composed of various impregnated resin and magnetic wires to examine the salt spray resistance, high/low temperature resistant moist heat alternating performance, dielectric dissipation factor and breakdown voltages, etc. of the system. It is shown that the wind turbine insulation system consisted of solvent-free polyesterimide impregnating resin, mica tape with polyester and molten polyimide lapped magnetic wire has lower dielectric dissipation factor, good salt spray resistance and high and low temperature insulation performance and is one of the best insulation systems with excellent insulation properties.
