输电线路元件强度匹配关系的研究

对国内外输电线路元件设计失效顺序进行了分析,建立了三种输电线路元件失效顺序模型,提出了元件强度匹配关系的计算方法。利用元件抗力统计参数,得出各元件在各种失效顺序下的强度匹配关系,给出了强度匹配关系设计应用实现措施和输电线路的失效原则,为实现输电线路差异化设计提供了参考。

Study on Match Relationship of Fittings Strength for Transmission Lines

Analysis is made on failure sequence of fittings design both at home and abroad, further three models for fittings failure sequence for transmission line are built up, then a computing method on match relationship of fittings strength is proposed. Strength match relationship under different failure sequence is derived by using fitting resistance statistic parameter. As a result it gives measures for strength match relationship implementation and failure principle of transmission line as well, thus providing reference for differentiated planning for transmission lines.
