摘　　要：某炼钢厂LF炉所用的SVC装置发生PT高压保险熔断、避雷器频频动作、电缆头放炮等异常运行情况。对这一现象进行了深入分析,认为是由于FC滤波支路失谐度过大造成的,并提出了相应的对策和建议,以保证SVC装置的安全可靠性。Abnormal operating conditions such as PT high voltage fuse burning out, ac-tion of lightening arrester and cable head sparking occurred in the SVC device for the LF furnace in a steel plant. Through deepened analysis it was found that the phenomenon was caused by excessive detuning in the FC filter circuit. Relevant countermeasures and sugges-tions were also put forward, to ensure the safety and reliability of the SVC device.
