摘要:
文中针对一起220 kV GIS设备在运行过程中产生的异响缺陷,结合现场停电解体检查,对可能引起设备异响的原因做了详细的分析和验证。结果表明,内部放电及内部紧固件松动导致的设备异常振动都可引起设备异响及局部放电检测结果超标,该次缺陷的原因为设备在安装时没有将卡簧装入卡簧槽,造成卡簧始终卡在导杆上,在长期的运行过程中产生了不可恢复的变形,伴随着导杆的热胀冷缩,卡簧与导杆存在的微弱位移使得卡簧最终落入卡簧槽,然而形变使得卡簧与卡簧槽尺寸不匹配,在高电压、大电流情况下,屏蔽罩与卡簧在电磁力的作用下产生异常振动,引发设备异响。总结该缺陷的经验,为了避免同类缺陷的再次发生,建议在设备生产制造阶段进一步完善设备安装工艺管控措施,在设备运维阶段加强放电类及机械类缺陷检测与诊断分析,在设备出现缺陷时第一时间明确缺陷原因,并采取针对性措施,严防缺陷发展为故障。
Abstract:
An abnormal noise defect occurred in operation of a 220 kV gas insulated switchgear (GIS) is analyzed in detail by means of overhaul inspection, and the possible causes of the abnormal noise are discussed. The result shows that both the abnormal vibration of the GIS due to loose of the internal fastener and the internal discharge can cause the abnormal noise and make the partial discharge exceed the standard. This abnormal noise defect is due to that the spring was not put into the spring slot in the GIS installation, so it was clipped on the guide rod to suffer non-recoverable deformation during long-time operation process. Although the weak displacement between the spring and the guide rod caused by thermal expansion and cold contraction made the spring eventually fall into spring slot, the deformation led the spring not to match the spring slot. Consequently, abnormal vibration of the shield and spring happened under high voltage and large current as well as the effect of electromagnetic force, resulting in the abnormal noise of the equipment. To avoid this kind of defects, some precautionary measures are suggested as follows: 1) In the equipment manufacturing phase, the control of equipment installation should be improved; 2) In the equipment operation and maintenance phases, the detection and diagnosis analysis of discharge and mechanical defects should be strengthened; and 3) Once defect is detected, the cause of the defect should be clearly defined in time, and pertinent measures should be taken to prevent the defect from developing to a failure.
