电力设备缺陷直接威胁电网运行安全，文中通过对新疆750 kV变压器故障的DGA数据进行分析和故障诊断，并结合变压器解体检查证实诊断结论，再从套管结构分析探索和发现该设备的结构设计缺陷，确定诱发故障的真实原因并提出有效的消缺措施建议。
Electric equipment defects directly threaten the running safety of power grid, and DGA data in this paper are analyzed and diagnosed to the faults happened in Xinjiang 750 kV transformer. Associated with the factory check the conclusion is validated, and the bushing design defect is explored and found from the structure analysis of this bushing to decide the real reason induced the fault in transformer, while the efficacious suggestion to de-defect way is proposed.
