摘　　要：本文介绍了计算大型变压器大电流引线漏磁场的互补变分方法，通过各种方案的实际计算和比较，得到几点防止变压器油箱局部过热的措施。The complementary variational method is used in computing the leakage magnetic field due tO current carried by the lead wire in a huge transformer. By compering the resultS, can get the method for decreasing the loss of transformer oil tank. In the meantime, the results obtained show that the complementary variational method can be used in the computation of practical engineering problems.
