摘要
雷电绕击是造成特高压输电线路跳闸的主要原因。根据国内外输电线路现有防雷技术及运行经验,综合分析几种防雷电绕击实用新技术,并且探讨各防雷技术用于特高压交流输电线路的可行性及适用范围,以期为我国1 000kV特高压交流输电线路防雷电绕击提供支持。
Lightning shielding failure is the major reason for trip on UHV transmission lines. In accordance with present lightning protection technology and operating experience both here and abroad, the paper comprehensively analyzes several kinds of operative technologies of lightning shielding failure and discusses scope and feasibility of applying lightning protection technologies in UHV alternating current transmission lines, in the hope of providing reference to anti-lightning shielding of domestic 1 000 kV UHV alternating current transmission lines.
