摘　　要：为了整体把握架空输电线路体系的可靠性,综合考虑了现行输电线路各组件的安全度水平、建造成本、破坏修复时间和费用,采用强度匹配理论开展了架空输电线路体系强度匹配设计方法研究,提出了输电线路体系各组件的5种失效顺序、体系的强度匹配设计方法及其相应的匹配系数。所提方法与现行设计方法的对比分析表明,大部分体系组件的安全度水平可与现行规范保持一致。采用强度匹配设计方法可实现不同架空输电线路体系的差异化匹配设计。In order to fully grasp the reliability of the overhead transmission line system,we studied the design method of overhead transmission line system based on strength matching theory after comprehensively considering the safety level,the construction cost,damage repair time and cost of each component of current transmission lines in China.Moreover,we proposed five failure sequences for each component,a design method for strength match of the transmission line system and the matching coefficients.The comparative analysis of the method in this paper with the current design method in China shows that most of the components can be kept in line with the current standard level of the reliability.The design method for strength match can realize the differentiated matching design for different overhead transmission line systems.
