摘　　要：螺杆式启闭机在水电站平板闸门启闭控制应用较为普遍,但在运行中常因闸门卡塞,导致启闭机损坏事件时有发生。如何配置完善螺杆启闭机保护,实现螺杆启闭机远方控制,是值得探讨的课题。结合某电站通过增加螺杆启闭机保护,提出了设计与保护配置的建议。Screw hoist is widely used in the control of flat gate in hydropower stations.While in practical operation,hoist damage caused by gate jam occurs frequently.Thus,it is of great concern to set up an overload protection and realize the remote control of the screw hoist.Based on the practical work experience in a power station,suggestions on the design and configuration of the protection are proposed.
