摘要为了研究电力变压器内部由导磁钢板（Q235B）组成的结构件（如铁心拉板、变压器油箱等）在直流偏磁工作状态下的杂散损耗特性。本文提出了一种基于漏磁通补偿的杂散损耗模拟方法，设计和研制了相关的实验模型，并进行了详细地实验研究和对比分析。重点考察不同程度的直流偏磁激励下导磁钢板的杂散损耗和漏磁通分布，研究交流激励和直流激励之间的交叉作用对杂散损耗特性的影响。通过详细地模型实验研究，分别获得了电力变压器内由导磁钢板组成的结构件在标准的正弦激励作用和直流偏置激励作用时的杂散损耗和漏磁通的分布情况并进行了对比分析。所得实验数据、结果和结论可为电力变压器的电磁设计和优化提供参考，具有一定的工程实用价值。

Abstract：In order to study the stray-field loss properties of the transformer structural parts under various dc biased condition, which are made of the magnetic steel plate(Q235B), a test model with compensator of leakage flux is proposed and manufactured in this paper. The distribution of stray-field loss is investigated in detail based on the test model. The different electromagnetic behavior of the magnetic steel plate under the interaction between the ac exciting source and the dc exciting source is also examined. The stray-field loss and leakage flux of magnetic steel plate under different dc-biased magnetizations is obtained experimentally and the comparison of measured results is carried out. These have important significance in improving the performance of magnetic shielding by optimizing design.

Key words： Power transformer DC bias magnetic steel plate stray-field loss
