摘要
介绍了220kV中山变电站气体绝缘金属封闭开关设备(gas insulated metal enclosed switchgear,GIS)电流互感器(current transformer,CT)气室异响和解体检查处理情况,分析表明异响和异常振动是由于CT填充件和紧固夹件断口错位导致磁路闭合并构成振动系统而形成,并针对这一原因提出了改进建议。
This paper describes abnormal sound from current transformer（CT） chamber of the gas insulated metal enclosed switchgear（GIS） in 220 kV Zhongshan Substation,and presents the strip inspection and processing.Analysis showed that the inconsistent fracture location of filling part and fastener led to closed magnetic circuit,and constituted a vibration system,then produced abnormal sound and vibration.The recommendations for improvement are put forward.
