摘要
采用故障树法研究整流变压器的可靠性,建立了整流变压器的故障树模型,利用下行法求出系统的最小割集,并指出系统易出故障的关键环节;在确定底事件发生概率时,采用统计数据与专家评价相结合的方法,计算整流变压器的可靠度,该方法为进一步研究故障树中的模糊性提供了思路。
The fault tree method was adopted to study the reliability of rectifier transformer, the fault tree model of rectifier transform- er was established, the downstream method was used to get minimal cut sets of the system and this paper pointed out key links in which the system faults easily took place. In determination of bottom-event probability, statistical data was combined with expert evaluation to calculate the reliability degree of rectifier transformer. The method provides a thinking way for further studying fuzzy in fault tree.
