摘要
本文中作者介绍了一起某110kV变电站主变重瓦斯跳闸事故,从保护装置信息记录检查、相关电气试验等方面分析了故障原因,推测了主变绕组变形位置,并通过现场检查和返厂解体验证推断的准确性。
In this article, the author introduced a heavy gas trip accident on the main transformer of a 110 kV substation. Based on protection device information record inspection and related electrical tests, the causes of heavy gas tripping is analyzed. The deformation position of the main transformer winding was estimated, and the accuracy of the inference was verified through on-site inspection and disassembly of the factory.
