摘要
针对继电保护装置平均失效间隔工作时间(MTBF)指标混淆于装置使用寿命的情况,阐述了继电保护装置MTBF指标的含义,提出MTBF指标的三种计算方法,即可靠性预计、可靠性试验、现场失效数据统计,探讨了继电保护装置MTBF指标与装置寿命的关系,并给出标准指标的取值建议。
In allusion to the condition that the mean operating time between failures （MTBF） of relay protection equipment was confused with the life of relay protection equipment, this paper explained the definition of the MTBF index and presented three different methods for the calculation of the MTBF index of relay protection equipment, including reliability prediction, reliability test, and site failure data statistic, then analyzed the relationship between the MTBF index and the life of relay protection equipment, and raised the recommended values of the MTBF index at last.
