超导故障限流器现状及其实用化研究方向探讨

A Research on Superconducting Fault Current Limiter and its Application Analysis

超导故障限流器(Superconducting Fault Current Limiter,SFCL)的开发已成为近年来各国限流技术研究的前沿课题之一。文章结合SFCL的主要分类,指出了几种SFCL的特点与不足。针对现今的研究热点,着重介绍了电阻型、磁屏蔽型、饱和铁芯电抗器型、桥路型等几种实用性较高的SFCL工作原理及实现方案,并就其主要研究成果进行总结与评述。文章还根据SFCL研究的现状及工程应用经验,指出了实用化研究中需要解决的一些关键问题,以期为SFCL的开发和选择限流措施提供参考。

The exploitation of superconducting fault current limiter（SFCL） has been gained highly recognition by many countries and becomes one of the advanced subjects of current limiting technology research in recent years. In accordance with a type of main classification about SFCL,the article points out some traits and lacks of several types of SFCL. In view of researching hot spot at present,the operation principles and implementation of several SFCL with application value,such as the resistive type,magnetic shield type,saturated core type and bridge type SFCL are introduced emphatically in the article. Furthermore,it reviewed and discussed the main research results of the above type of SFCL in recent years.Based on the current situation of research and experience of engineering application,the article also points Out the key issues needed to be solved in pragmatizing research,which may be the reference to SFCL exploiture and the choice of current limiting measurement.
