云南—广东特高压直流滤波器电抗器故障分析
摘要
直流滤波器电抗器运行工况较为复杂
运行维护经验极为欠缺。通过介绍云广工程穗东站极2直流滤波器L
2
电抗器起火事件
认真分析了引起故障的所有可能原因
最终确认引起故障的根本原因是该电抗器采用的降噪装置内吸音棉未达到阻燃等级
并提出了停电状态和非停电状态运维建议
丰富了直流设备运维经验
有力保证了设备安全稳定运行。
Abstract
The operation condition of DC filter reactor is much complicated and maintenance experience is extremely deficient.In this paper
the fire accident of DC filter L
2
reactor in Sui-dong substation pole 2 of Yun-guang project is introduced
all possible reasons causing the accident are analyzed carefully.It is finally confirmed that the root cause of the accident is that the sound-absorbing cotton of noise reduction device adopted in the reactor did not achieve flame retardant grade.The operation and maintenance suggestions in power on and off condition are put forward
which enriches operation and maintenance experience and assures safe and stable operation of DC equipments.
