Abstract

Abstract

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.
- Instrument and Control switches,
- Failure data,
- Reliability analysis,
- Parameter estimation
