摘　　要：对广东省几例进口变压器由于机械强度不够,经受不起短路电流的冲击,线圈发生变形,导致事故发生的情况进行了介绍,分析了变压器机械强度设计、制造的不足,提出了处理改进措施,为有关变压器的设计、制造、选型提供参考。This paper describes several failures of imported transformers in Guangdong, China, which were caused by low transformer mechanical strength, the resultant failure to withstand short-circuit current and the ensuing distortion of transformer windings. Defects in transformer design and manufacture are analyzed and some improving measures also presented, which is of referential value to the design, manufacture and type selection of transformers.
