摘　　要：基于仪控开关现场失效数据,分别应用指数分布以及威布尔分布对仪控开关进行可靠性参数估计。对于无失效数据的情况,使用贝叶斯理论进行参数估计。分别得出了不同寿命分布类型开关的失效率。以大亚湾核电站实际使用的3种类型仪控开关为例,对其失效数据进行了可靠性评估,说明了方法的有效性。Based on the actual failure data,the reliability analysis of Instrument and Control switch,by means of Exponential and Weibull distribution,are given in this paper.For zero-failure data,the Bayesian statistical theory was used.Failure of switches with various lifetime distributions was obtained.The methods were tested on three kinds of switches which were used in Daya Bay Nuclear Power Plant and the results indicated its validity.
