摘　　要：介绍了采用射频监测仪和转子绕组匝间短路监测系统相结合在线监测发电机定、转子绝缘状况的方法,提出了发电机绝缘故障诊断的模糊专家系统。指出:将上述些方法相结合可以有效地实现对汽轮发电机绝缘状态的监测和故障诊断。A method of on line monitoring the insulation state of rotors and stators of turbo-generators is introduced, which makes use of a RF Monitor, in combination with an interturn short circuit monitoring system for rotor windings. A fuzzy expert system for insulation fault diagnosis of turbo-generators is further proposed. Simultaneous state monitoring and fault diagnosis of turbo-generator insulation can be effectuated by combining the above-mentioned methods. Refs 3.
