摘　　要：提出通过监测海上风机齿轮箱油液磨粒的方法来判断齿轮箱的运行状况。基于电感原理检测方法,根据铁磁和非铁磁磨粒的电磁属性不同,监测油液中最重要的磨粒参数。搭建试验台,进行半径为200μm、300μm、500μm、700μm的铁、铜磨粒试验检测,得到2种磨粒引起的电压变化为57.5 mV和-23.0 mV,273.0 mV和-109.0 mV,1175.0 mV和-470.0 mV,以及3500.0 mV和-1400.0 mV。试验表明,基于电感原理的齿轮箱油液磨粒检测方法是可行的,可用电压和极性检测磨粒的大小和磁性,得到磨粒引起的线圈电压变化:波谷表示检测到的是非铁磁磨粒,波谷峰值电压对应检测磨粒大小;波峰表示检测到的是铁磁磨粒,波峰峰值电压对应检测磨粒大小。该方法不需要齿轮箱停机再进行检查,降低停机带来的经济损失,具有很高的工程应用价值。The running condition of the offshore wind turbine gearbox is judged by monitoring the oil debris of the gearbox.The most important debris parameters in the oil are monitored based on the inductance principle detection method according to different electromagnetic properties of ferromagnetic and non-ferromagnetic debris.The test bench is built,the iron and copper debris with radius of 200μm,300μm,500μm,700μm is tested,and the voltage changes caused by the iron and copper debris are found to be 57.5 mV and-23.0 mV,273.0 mV and-109.0 mV,1175.0 mV and-470.0 mV,3500.0 mV and-1400.0 mV.It can be concluded that the oil debris detection method based on inductance principle is feasible,the voltage and polarity can be used to detect the size and electromagnetism of the debris,and the coil voltage change caused by the debris can be obtained.The negative voltage represents the detection of non-ferromagnetic debris,and the peak voltage is corresponding to the size of the detected debris.The positive voltage represents the detection of ferromagnetic debris,and the peak voltage value is corresponding to the size of the detected debris.The method does not need to stop the gearbox for inspection,reducing the economic loss caused by the shutdown,which is of engineering application value.
