摘　　要：为评价某风场国产齿轮油的使用性能,文中对4台不同风机中的齿轮油样品进行检测,包括运动黏度、黏度指数、倾点、酸值和微量元素等指标,分析该国产齿轮油在不同运行时间下各个指标的变化情况。结果表明:在风电齿轮箱运行期间,齿轮油的运动黏度未发生明显变化,仍能形成稳定的油膜保证齿轮箱的正常运行;黏度指数及倾点变化较小,齿轮油低温性能无明显变化;齿轮油的磨斑直径指标无劣化趋势,油品能够在齿轮表面形成保护层,使齿轮间有效啮合;酸值在运行期间无明显变化,齿轮油没有发生明显的氧化;齿轮油中的微量元素无异常增加的情况,风电齿轮箱无异常磨损。以上结果表明,各项检测指标均满足要求,该国产齿轮油满足该风场风电齿轮箱的使用需求。To evaluate the performance of domestic gear oil used in a wind farm,samples of gear oil from four different turbines were tested in the paper,including indicators such as kinematic viscosity,viscosity index,pour point,acid value,and trace elements.The changes of these indicators under different operating times were analyzed.The results showed that during the operation of the wind tur-bine gearbox,the kinematic viscosity of the gear oil did not change significantly,and it could still form a stable oil film to ensure the nor-mal operation of the gearbox.The changes in viscosity index and pour point were small,indicating no significant change in the low-tem-perature performance of the gear oil.The indicator of the wear scar diameter on the gear oil showed no deterioration trend,indicating that the oil could form a protective layer on the gear surface,ensuring effective meshing between the gears.The acid value did not change sig-nificantly during operation,indicating no significant oxidation of the gear oil.The trace elements in the gear oil did not show abnormal increase,indicating no abnormal wear in the wind turbine gearbox.The above results indicate that all the tested indicators satisfy the re-quirements,and domestic gear oil meets the usage needs of the wind turbine gearbox in the wind farm.
