摘　　要：对我国小水电的电气设备进行安全性分析,建立了电气设备故障率的故障树模型,选择坝顶配电室为故障树的顶事件,并用下行法求出了该故障树的最小割集,通过对浙江省某小水电站进行电气设备故障概率计算,获得电气设备故障对顶事件造成的故障安全影响程度,结果表明线路上的开关设备是导致故障树顶事件发生的重要设备元件,直接影响着整体供电系统的安全可靠性。The overall reliability of electrical equipment of small hydropower station is analysed in this paper. Fault tree model of components＇ failure rate is established. With dam top as the the fault tree top events, Minimum cut set and solution of the fault tree are presented in the Paper. Through the calculation of the electrical equipment failure probability of a small hydropower station in Zhejiang province, the safe influence degree of the electrical equipment failure to the top events is obtained. The results show the switch equipment on the key circuits is the important e- quipment component,which causes the top event and impacts the overall safety and reliability of the power supply system directly.
