高压直流交联聚乙烯电缆运行与研究现状

Application and Research Status of High Voltage Direct Current Cross-linked Polyethylene Cable

随着经济持续快速发展,世界各国电力能源需求快速增长,高压直流输电已经成为未来"智能电网"中的重要支撑。高压直流交联聚乙烯电缆作为构建直流电网的物理基础和关键设备,是直流电网研究与建设的重要基础。本文在总结直流电缆发展过程的基础上,对高压直流交联聚乙烯电缆的应用与运行现状进行了综述。针对交联聚乙烯电缆在运行中面临的空间电荷问题,综述了交联聚乙烯绝缘与电缆附件绝缘的研究现状与研究动态。

With the rapid development of economy, all the countries have to face the explosions of power energy requirements, and high voltage direct current （HVDC） transmission has been the main support for smart grid. As the key equipment, HVDC cross-linked polyethylene （XLPE） cable is an important foundation for the research and construction of HVDC transmission system. In this paper, the application and operation situation of XLPE cable was summarized based on the development process of HVDC cable, and the research status of space charge issues in the XLPE cables and accessory insulation was reviewed.
