【摘要】 随着柔性直流输电技术的发展,高温超导(HTS)直流电缆研究越来越受到各界重视。与超导交流电缆相比,低温绝缘结构HTS直流电缆损耗更低、传输容量更大,是HTS直流电缆的重要发展方向。本文在查阅国内外大量文献资料的基础上,结合绝缘介质在直流电场下暂态和稳态时的电场分布特点,综合考虑低温绝缘材料力学性能、绝缘特性、成本等因素,综述了HTS直流电缆低温绝缘材料的研究进展、存在的问题和发展趋势。更多还原

【Abstract】 With the development of flexible DC transmissions technology, the researches on high temperature superconductivity(HTS) DC cable attract more and more attention. Compared with the superconductivity AC cables, the HTS DC cable with cold insulation structure has lower dielectric loss and larger transmission capacity, which is the important development direction for the HTS DC cables. Combining with the electric field distribution characteristics of insulating medium in transient and steady state under DC electric field, and considering the influence factors of mechanical properties, insulating characteristics,cost of the cold insulating materials, we summarized the research progress, existing problems, and development trend of the cold insulating materials for HTS DC cable.更多还原
