基于故障树分析法的接触网可靠性分析

Reliability Analysis of Overhead Contact Line System Based on Fault Tree Analysis Method

针对接触网可靠性研究的不全面,基于故障树分析方法,对接触网系统的可靠性进行分析和研究。通过建立接触网失效故障树,对导致接触网失效的故障进行了定性以及定量分析。定性分析找出了导致接触网失效的所有故障组合;定量分析找出了容易导致接触网失效的故障类型,根据定性定量分析得到的结果,提出了有效提高接触网可靠性的相应建议,为接触网系统的设计、维修以及检测提供科学依据。

In view of the problem that there was a lack of comprehensive research on the reliability of overhead contact line system （OCS） , the paper carried out an analysis and research on the reliability of OCS based on fault tree analysis method. Meanwhile, after establishing the fault tree of OCS failure, this paper qualitatively and quantitatively analyzed the faults which would cause OCS failure. Through the qualitative analysis, all fault combinations that would cause OCS failure were found out; through the quantitative analysis, the types of faults which would be likely to cause OCS failure were also found out. Further, according to the result of qualitative and quantitative analysis, this paper put forward relevant suggestions about how to effectively improve the reliability of OCS, which can function as scientific basis for the design, maintenance and the detection of OCS.
