摘　　要：雷电是导致变压器故障的重要因素之一。针对一起35 kV变压器雷击故障,进行油色谱分析、绕组直流电阻、绝缘电阻试验,并结合返厂吊心检查,分析故障原因及过程,并提出了相应的预防性措施。As thunder is one of the most factors causing transformer failures, the oil color spectrum analysis,winding DC resistance and winding insulation resistance tests are carried out on the failure of a 35 kV transformer caused by thunder. The cause and process of the failure is analyzed according to the test results and inspections of transformer core in factory, and the corresponding preventive measures are put forward.
