摘要
分析一起500 kV SF_6气体绝缘电流互感器由于盆式绝缘子质量缺陷导致的内部放电故障,介绍该电流互感器的结构特性,推断内部放电故障发展过程,并从设备制造、试验维护、在线监测等方面提出防范此类事故的措施。
An internal discharge breakdown of 500 kV SF6 gas-insulated current transformer was analyzed caused by quality defects of bisc insulator. Structural characteristics of this type of current transformer and the developing process of internal discharge breakdown were introduced. Finally preventive measures were proposed from aspects of equipment manufacturing, test maintenance and on-line monitoring.
