摘　　要：鉴于轴电流的存在对发电机组具有很大的危害性,对柬埔寨达岱水电站1、2、3号发电机组故障进行了分析,根据分析的结果,提出了大轴接地、退出轴电流Ⅱ段保护连片等防范措施,以减少轴电流对发电机组的危害,保障机组安全稳定运行。The shaft current is of great harm to generator units. Based on the analysis of the practical experience in Cambodian Tatay Hydropower Station,several prevention measures are proposed,such as the shaft grounding,and removing the Ⅱ-section shaft current protection joint. It shows that those measures could alleviate the harm of the shaft current to the generator units and guarantee their stable operation.
