摘　　要：本文中作者介绍了一起500kV主变套管介损异常故障,结合拆解、试验过程对其介损异常进行了理论分析。分析结果表明介损异常的主要原因是老化,为同类型设备的故障诊断和运行维护提供一定的借鉴。The paper introduces the case of abnormal bushing dielectric loss of a 500kV main transformer. Combined with the disassembly and test process, the theoretical analysis results show that the main cause of the dielectric loss abnormality is aging, which provides some reference for the fault diagnosis and operation and maintenance of the same type of equipment.
