摘要
由于接触网故障占牵引供电系统故障的绝大多数,所以牵引供电系统的可靠性很大程度取决于接触网的可靠度。本文根据数理统计原理,利用故障树分析方法,对牵引供电系统接触网的可靠性进行了分析,得到了接触网电气部分及机械部分两方面的可靠度、平均故障时间、故障率等重要指标,并对这两方面进行了逻辑上的串联建模,提高了接触网可靠性分析的统一性。为牵引供电系统接触网的可靠性的设计、维护与科学管理提供了理论依据与新方法。
Since the majority of traction power supply system faults are catenary faults, the reliability of traction power supply system depends on the reliability of catenary to a large extent. Based on the theory of mathematical statistics and the FAT （Failure Tree Analysis）, this paper analyzes the reliability of traction power supply system catenary, obtains several important indices such as the reliability, mean time between faults and fault rate of both the electrical part and mechanical part of catenary. And this paper also carries out a logical series - modeling and improves the unity of the analysis of the reliability of catenary. Hence this paper provides theoretical foundation and new methods for the design, maintenance and scientific governance of the reliability of traction power supply system catenary.
