水电站机电设备在运行中,由于设备特性不同,工作条件各异,需使用各种性能的油,一般有润滑油和绝缘油两大类。润滑油又可分为透平油、机械油和润滑脂等。绝缘油也可分为变压器油、开关油、电缆油等。用量最大的为透平油和变压器油。透平油在设备中的主要作用是润滑、散 Hydropower station mechanical and electrical equipment in operation, due to different equipment characteristics, different working conditions, the need to use a variety of performance oil, there are two general categories of lubricants and insulating oil. Lubricant can be divided into turbine oil, machine oil and grease. Insulating oil can also be divided into transformer oil, switch oil, cable oil. The largest amount of turbine oil and transformer oil. Turbine oil in the device’s main role is to lubricate and disperse
