摘　　要：灯泡贯流式机组因为机组转动惯量小,一般采用重锤关机装置作为机组的防飞逸措施。文章简要分析介绍了乌金峡水电站重锤关机装置的运行特点,以及开展动水关闭机组试验的方法。Generally, weight-driven shutdown device is applied to prevent unit from runaway because of lower moment of inertia of bulb tubular turbine. In this paper, operation features of the weight-driven shutdown device and tests on shutdown in dynamic water of Wujinxia Hydropower Station is briefly introduced and analyzed.

关 键 词：重锤关机装置 结构特点 防飞逸措施 试验
