摘要
对一起罕见的500 kV变压器匝间短路事故及原因进行分析。通过对事故前后的油色谱、局部放电在线监测和最终解体分析,得出事故原因是高压绕组发生了匝间短路。针对事故原因,指出了造成匝间短路的因素,提出了预防措施。
This paper presented one rare short-circuit fault of 500 kV main transformer and its causes. A turn-toturn short-circuit fault on high-voltage winding was concluded from oil analysis and partial discharge results. The reasons related to the short-circuit was expounded, and some anti-accident measures were carried out.
