摘要
输电线路作为电力系统的重要组成部分,其可靠程度将直接影响到电力系统的运行可靠性.架空输电线路绝缘地线兼有防雷保护、通信和融冰等作用,绝缘地线的运行状态对电力系统的可靠性起着至关重要的作用.本文分析了可能导致架空输电线路绝缘地线掉线的原因,建立了以绝缘地线掉线为顶事件的故障树,并对故障树进行了定性分析.
The transmission line is an important part of the power system; its reliability will directly affect the reliability of the power system. The overhead insulation grounding lines are used for lightning protection, communication and melting ice, etc, The reliability of the insulation grounding lines play a crucial role for the power system reliability. This paper analyzes the causes of the falling of overhead insulation grounding lines and establishes a fault tree, and then to make qualitative and quantitative analysis of the fault tree.
