摘要
针对一起110kV GIS母线TV分支气室局放异常缺陷,开展了超声波局部放电带电检测。结合局放信号源超声波精确定位,经定性分析,综合判断该气室内部存在连接件松动的可能。考虑设备长期运行,内部连接件松动会产生放电和故障隐患,建议结合气室内部结构图纸进行停电解体检查。
In this paper,considering an abnormal defect of partial discharge in 110 kV GIS bus air chamber,the ultrasonic partial discharge(PD)live detection is carried out.Based on the precise location of partial discharge signal source and qualitative analysis,the possibility of loosening connectors in the gas chamber is judged comprehensively.Considering the long-term operation of the equipment,it is suggested that the outage electrolytic examination should be carried out in combination with the internal structure drawings of the gas chamber.
