故障树分析法在油断路器故障预测中的应用

Application of Oil-breaker Fault Forecast by Analytic Approach to Fault Tree

通过对故障树分析法的研究,给出故障树数学模型、顶事件故障率算法和底事件重要度算法,并应用于油断路器故障预测,结果表明用故障树方法对系统进行故障分析,能够清晰发现对顶事件发生影响最大的因素,为农网故障提前预测和故障预防工作提供依据。

Through the analytic approach on fault tree, the fault tree mathematics model, the arithmetic of top incident fault rate and the arithmetic of bottom incident importance were given. All of them were used in oil circuit breaker failure predication. The results indicated that the fault tree in could clearly find the most influential factor happens in the top incident, which provides the basis on the rural power grids trouble predicted and trouble prevention work.
