摘　　要：油浸式超大容量变压器外部件局部过热发生典型部位,主要集中在大电流引线附近,是由大电流产生的磁通所造成的。本文作者通过应用三维模型仿真技术,控制结构件中杂散损耗,防止局部过热,并通过试验进行验证,对于过热部位给出相应的解决方案。The typical location where local overheating occurs in the external components of oil immersed ultra large capacity transformers is mainly concentrated near the high current lead wire,which is caused by the magnetic flux generated by the high current.By applying three-dimensional model simulation technology,controlling stray losses in structural components,preventing local overheating,and verifying through experiments,corresponding solutions are provided for overheated areas.
