摘  要:为研究风力发电机绝缘系统的耐海上环境气候性,制备了风力发电机绝缘系统模拟试样,并对其进行冷热循环、恒定湿热和持续盐雾的环境耐受试验,分周期测量介质损耗因数和绝缘电阻等非破坏性介电特性参量以及剩余击穿电压,并对绝缘材料的宏观和微观结构进行剖析。结果表明:经加速环境耐受试验后,线圈绝缘与铁心的界面产生了微裂缝或剥离,绝缘的介电性能虽有下降但仍然处于正常的指标范围内,表现出良好的耐候性。In order to study the marine environmental resistance of insulation system of offshore wind tur-bine generator, simulation samples of insulation system of the offshore wind turbine generator were pre-pared, and some non-destructive dielectric parameters of dielectric dissipation factor and insulation resis-tance and residual breakdown voltage were measured at different periods after thermo-cold cycling, steady damp heat and salt spray test. The micro-structure of the insulating material was analyzed by microscope. The results show that after the accelerated environmental resistance test, the micro-crack or peeling gener-ate between the coil main insulation and the core, and the dielectric properties of the insulation system decreases but the performance index is still in the normal range, showing excellent environmental resis-tance.
