摘要
以低温能源液体作为超导电缆的冷媒,实现电力和燃料一体化输送,可以提高能源输送整体效率,降低综合成本,节约土地资源,为长距离、大容量能源输送提供了新思路。随着对超导材料研究的深入,越来越多的超导材料被发现,并逐渐实现了商业化生产。在此过程中,人们不断探索新的能源液体和超导材料,以满足电力和燃料一体化输送的要求。该文介绍两种电力与能源液体的双重输送管道——液氢-超导能源管道和液化天然气-超导能源管道,讨论适用于这两种能源管道建设的超导材料,分析它们的发展现状以及性能特点。此外,报告了我国“十三五”国家重点研发计划“超导直流能源管道的基础研究”项目中超导材料选材工作,确定了项目最终选用Bi2223/Ag带材,并介绍了在选材过程中获得的一些关键实验结果。最后,对满足电力与能源液体双重输送管道建设的超导材料的发展前景进行了展望。
Using cryogenic energy liquid as the refrigerant of the superconducting cable to realize the integrated transmission of power and fuel can improve the overall efficiency of energy transmission,reduce comprehensive cost,save land resources,and provide a promising idea for large-capacity energy transmission over long distance.With the in-depth study of superconducting materials,more and more superconducting materials have been discovered and gradually realized commercial production.In this process,researchers keep to explore the appropriate selection and combination of the energy liquid and the superconducting material to satisfy requirements for the transmission of power and fuel in an integrated pipeline.In this paper,two kinds of integrated transmission pipeline for power and energy liquids were introduced,i.e.,liquid hydrogen superconducting energy pipeline and liquefied natural gas superconducting energy pipeline respectively.The superconducting materials possible for these two kinds of energy pipelines were discussed,and the development status and performance characteristics of the materials were analyzed.Moreover,this paper focused on reporting the work of the superconducting material selection for the"Basic Research on Superconducting DC Energy Pipeline"project of The National Key Research and Development Program in the 13th Five-Year Plan for Economic and Social Development of China.A type of Bi2223/Ag tape was selected for this project.Some key experimental results attained in the selection process were presented.Finally,the future prospective superconducting material development for power and fuel integrated transmission pipelines were discussed.
