摘要
为了保证继电保护设备可靠性以及电力系统安全、稳定运行,本文设计了一种等效应力和等效基础失效率的计算方案,用以发现装置可靠性的薄弱环节和不同部件受不同应力影响的程度.并且本文设计了温度加速寿命实验,以评估装置可靠性,最后将实验结果与计算结果相比较,从而得出结论,本文所设计的装置寿命计算方式,其准确度更高,相比传统计算方式,更能体现装置的实际寿命.
Abstract
In order to ensure the reliability of relay protection equipment and the safe and stable operation of the power system,this paper designs a calculation scheme of equivalent stress and equivalent foundation failure rate,which is more efficient and accurate than the traditional calculation method.In this paper,a temperature-accelerated life experiment is designed to evaluate the reliability of the device,and finally the experimental results are compared with the calculated results to draw conclusions.
