摘　　要：汽轮发电机集电环的是励磁系统中的重要设备,它的作用是收集励磁中的直流电并导入转子绕组中,为定子绕组创造高速旋转的感应电磁场。其工作特点是环境温度高,流通电流大,转动速度高,并与碳刷高速摩擦。因此,及时处理碳刷过热故障对机组和电网安全运行有着重要的意义。The collector ring of the turbogenerator is an important equipment in the excitation system,and its function is to collect the DC current in the excitation and introduce it into the rotor winding to create a high-speed rotating induced electromagnetic field for the stator winding.The utility model is characterized by high ambient temperature,large current,high rotation speed and high-speed friction with the carbon brush.Therefore,it is of great significance to deal with the overheating fault of carbon brush in time for the safe operation of the unit and power grid.
