摘　　要：现阶段GCB/GIS可靠性设计相对薄弱,断路器传动轴是GCB/GIS连接操动机构驱动机械与灭弧室的关键零部件,笔者建立传动轴强度-应力(SSI)设计模型,以强度、应力基本数据处理方法探讨传动轴可靠性设计,为GCB/GIS结构进行可靠性设计尝试新思路。At present, the reliability design of GCB/GIS is relatively ＇weak. The transmission shaft of circuit breaker is the key component which connects the drive part of operation mechanism to the interrupter. The authors established the strength-stress interference （SSI） model of the transmission shaft, and discussed the reliability design of transmission shaft with the basic data processing methods of strength and stress. It is the attempt to the reliability design for the structures of GCB/GIS.
