摘　　要：为监测并评价某风场在用国产齿轮油使用性能及8台兆瓦级风机的运行状态,对影响齿轮油劣化和齿轮箱寿命的指标:运动黏度、水分、酸值和金属元素含量进行检测,分析在用齿轮油在不同运行时期的各指标变化情况。结果表明:在5年运行期间内各风机齿轮油的运动黏度变化率最大为0.97%、最小为0.03%,未发生明显变质,仍能形成稳定油膜确保齿轮箱和风机安全运行;酸值波动和增加趋势相对较小,油品未发生明显氧化变质,对齿轮箱运行稳定性影响较小;铁和铜元素无异常增加,油品极压抗磨性良好;水分含量均在指标范围内,对风机润滑系统的润滑性能影响较小,建议仍需定期监控齿轮油的水分含量,避免过多残留水分等杂质物存在对新油造成二次污染,延长齿轮箱使用寿命。国产在用油各项关键性能指标变化均处在正常变化范围内,该国产齿轮油满足兆瓦级风电设备的润滑要求。To monitor and evaluate the performance of domestically produced gear oil in use and the operating status of 8 megawatt-class wind turbines in a wind farm,indicators that affect the deterioration of gear oil and the lifespan of gear boxes,such as kinematic viscosity,moisture content,acid value,and metal element content,were detected.The changes in various indicators of in use gear oil during different operating periods were analyzed.The results show that during the 5-year operation period,the maximum viscosity change rate of each fan gear oil is 0.97%,and the minimum is 0.03%,with no significant deterioration observed,thus maintaining a stable oil film essential for ensuring the safe operation of gearboxes and wind turbines.The fluctuation and increasing trend of acid value are relatively small,indicating no significant oxidative deterioration of the oil and minimal impact on gearbox operational stability.No abnormal increases in iron and copper elements were detected,demonstrating that the oil maintained good extreme pressure and anti-wear properties.Moisture content is within the indicator range and has a relatively small impact on the performance of the wind turbine lubrication system.It is recommended to regularly monitor the moisture content of the gear oil to avoid excessive residual moisture and other impurities that may cause secondary pollution to the new oil,thereby extending the service life of the gearbox.Overall,the changes in key performance indicators of the domestically produced gear oil remained within normal ranges,indicating that this domestically produced gear oil meets the lubrication requirements of megawatt-class wind power equipment.
