摘　　要：提出了电站设备易损件的寿命评定方法,给出了易损件寿命数据的统计分析、分布检验、参数估计的方法,平均寿命、可靠度与可靠寿命的计算方法,易损件失效后果分类方法,易损件更换周期的确定方法以及常用计算公式.介绍了电站设备易损件寿命管理系统的功能,并给出了应用实例.应用易损件寿命评定方法及寿命管理系统,可以在使用阶段确定易损件的更换周期,为易损件的检修与更换以及电站设备的优化检修提供技术依据.Some life assessment methods for easily damaged power equipment components are presented, together with methods of statistical analyzing, distribution checking, parameters estimating, and calculating for mean life, reliability as well as the reliable life. Some classification of failure consequences and a method of determining the replacement period for easily damaged components are given together with formulas in common use. Functions of a life management system for easily damaged power equipment components are explained, accompanied by some practical examples. With this life assessment method and life management system, the replacement period of the components can be determined during their service stage. Therewith a scientific basis is provided for maintenance and replacement of the easily damaged components, and especially for optimized planning of the power equipment.
