摘　　要：为了防止和减少变压器故障和事故的发生,笔者应用油中溶解气体分析与绕组变形试验相结合的方法,全面分析典型的突发短路故障造成变压器损坏的原因、故障性质和故障部位,结合实例从生产工艺、结构改进、质量控制分析如何提高变压器抗短路能力。A combination method of dissolved gas analysis and winding deformation test is used for the analysis of typical power transformer damages due to sudden short circuit faults. To prevent the damages and improve the anti-short circuit ability of a power transformer, some methods are suggested, such as improving the transformer structure, production process, quality control and analysis, and so on.
