摘要 介绍了某电厂倒闸操作引发铁磁谐振现象,分析了电压互感器产生非对称的三相电路的原因,总结了运行操作的经验教训,提出了防止铁磁谐振的预防措施,并指出应加强运行人员的技能培训工作,以有效防止电力设备的破坏。 The ferromagnetic resonance phenomenon caused by switching operation in a power plant is introduced, and the cause of asymmetric three-phase circuit in voltage transformer is analyzed. Meanwhile, the experience and lessons of operation are summarized, and the preventive measures against ferromagnetic resonance are put forward. The technical training of operators should be strengthened, in order to prevent the damage of electrical equipment effectively.
