  • 摘要: 变压器油中铜颗粒污染物的存在极易影响油液的理化性能,甚至导致重大生产事故,因而根据ISO4406:1999标准,配制了24组不同污染度的含铜颗粒油样并通过实验测试了变压器油样的运动黏度性能(40℃),获得了实验范围内铜颗粒污染度对油液运动黏度的影响规律;然后根据测试数据采用偏最小二乘(PLS)法和支持向量机(SVM)法建立了油样中不同粒径、含量的铜颗粒与油液运动黏度的数学模型,探讨了不同粒径、含量的铜颗粒污染物对油液运动黏度的影响规律。结果表明:随着铜颗粒污染度的增加,油液的运动黏度减小;铜颗粒污染物粒径在15~25 μm范围内对油液运动黏度的影响较大,且粒径越大,油液运动黏度也越大;所建立SVM模型对验证集进行预测的相关系数和均方根误差(RMSE)分别是0.962 6、4.597×10-5。为消除实验误差,减少人为因素的影响比较准确地掌握铜颗粒污染物对油液运动黏度的影响提供了新的途径。
