摘　　要：高温超导变压器是通过用高温超导带材取代铜导线绕制超导绕组,液氮取代变压器油作为冷却介质,超导绕组在液氮环境中运行,以达到提高能效并减少电力传输损失的变压器。针对高温超导变压器的绕组设计,从超导变压器的绕组材料、绕组结构、绕组布局三方面比较了近年内美、日、韩、中国等具有代表性的高温超导变压器绕组的研究现状,通过综合比较和分析国际上各种主流复合超导体的结构特征,设计方法等关键技术,提出了未来高温超导变压器的绕组设计需要以提高临界电流,减少绕组漏磁场尤其是其径向分量,以及降低交流损耗为目标。With the improvement of high temperature superconductor practical performance, research and development with regard to practical applications of HTS transformers have been progressed actively in the world. High Temperature Superconduct- ing （HTS） transformer was to reduce the energy loss by replacing normal conductor windings with superconductor windings. The paper described the status of research and development of the windings of high temperature superconducting transformer from three aspects as high temperature superconductivity material, structure and layout. Through comparison and analysis of all kinds of HTS tape cabling methods in the world, the goal of the winding of high temperature superconducting transformer was to improve the critical current, reduce the leakage magnetic field, especially its radial component, and reduce the AC loss in the design.
