高温超导变压器研发进展综述

Review on R&D Progress of High Temperature Superconducting Transformers

与传统常规变压器相比,超导变压器具有很多优势,如体积小、重量轻、损耗低、无污染火灾隐患等。近十几年来,随着高温超导线材取得重要的研究进展,国际上相继开展了高温超导变压器的研发,已有三台样机成功地完成了挂网试验。简要介绍了近年来国内外高温超导变压器(包括电力变压器和机车变压器)的研发情况以及近期几个基于第二代高温超导线材的高温超导变压器项目,并指出随着高温超导线材的技术发展,限流变压器的研究值得关注。

Comparing with the conventional transformer, high temperature superconducting （HTS） transformer has more advantages, such as small volume, light weight and low loss without pollution or fire hazard. In past decades, great progress on the development of high temperature superconducting （HTS） wires has been made, research and development of HTS transformer have be progressed worldwide. At present, three HTS transformer prototypes successfully operated in grid. This paper briefly introduces the research and development of both the HTS power transformer and the transaction transformer in domestic and abroad in recent years, as well as several recent projects of HTS transformers based on 2G HTS wires, pointing out that as HTS wires developing, the research in limiting current transformers is worthy of attention.
