主设备多重故障发生概率分析方法

摘要

The important main equipments usually have safety systems or standby systems to support-But severe problems are caused because of multiple faults. Aim at this circumstance, probability analysis method for multiple faults and approximate estimation is advanced according to the features of the long usage of main equipments and periodic functional detecting of safety systems (standby systems). In addition, the affected factors about multiple faults occurrence are analyzed. The methods put forward can be applied to the analysis of multiple faults on main equipments in engineering.%重要的主设备一般有安全系统或备用系统支持,它们由于多重故障会造成严重的故障后果.针对重要主设备的多重故障问题,根据主设备长期使用和安全系统(或备用系统)定期功能检测的特点,提出了多重故障发生概率分析方法,以及近似估计方法,进行了多重故障发生概率影响因素分析.所提出的方法,可应用于工程中重要设备的多重故障发生概率分析.
