面向空间应用的新型滚动汇流环关键技术与启示

The key technologies of novel roll-ring for space applications

大型航天器(空间设施)对大功率、长寿命、高可靠电传输装置的需求日益迫切。文章介绍了滚动汇流环的原理、优点及其在"自由号"空间站的应用;并汇总分析了国外典型产品以及滚动汇流环技术的国内外研究现状;梳理归纳了为实现滚动汇流环技术的空间应用所亟需开展的研究工作。

With the demands of higher power,longer life and higher reliability in space applications,the traditional slip-ring faces big challenges,which becomes one of the key problems in developing large-scale spacecraft.This paper discusses the principle and the excellent performance of the roll-ring,and its applications on the Space Station Freedom.Some foreign typical products and researches for the roll-rings are reviewed;some key investigations in the application of the roll-ring technology in China are suggested.
