摘要:

    超導現象發現100年以來，各類新型超導體層出不窮，然而由于本征特性、低溫條件、合成技術及環境因素等限制使許多超導材料失去了實用性。首先簡要概述了超導材料的應用，特別是在先進電網中的應用需求和前景，分析了國內外幾種典型的實用超導材料的發展趨勢和市場需求情況。給出了主要發達國家及我國的超導發展計劃，指出了當前發展新型電力傳輸材料——第二代高溫超導帶材的必要性，并以上海市為例粗略展望了第二代高溫超導帶材及其強電應用技術包括城市電纜、超導限流器、超導變壓器、超導電機等發展對社會生活和傳統產業的重要影響和貢獻。

Abstract:

Since the superconductivity was discovered a century ago, various new superconductors have been found endlessly. However, a number of superconductors have lost their practical applications duo to limitations from the intrinsic properties, low temperature requirement, synthesis conditions, and environmental factors. A variety of applications for superconducting materials are summarized particularly with respect to the field of advanced power grids in the near future. The development and evolvement of practical superconducting materials are analyzed, together with the market demands. National projects regarding superconducting applications for a few major advanced countries are introduced as well, and the necessaries, significance and contributions to the society for development of the secondary generation superconducting tapes and relevant novel superconducting devices, such as grid cables, fault current limiter, power transformer, and motor etc. in the metropolis like Shanghai, are roughly indicated
