Break pin state on -line monitoring component for hydraulic turbine

The utility model relates to a break pin state on -line monitoring component for hydraulic turbine is by contact lid, O type rubber seal, move contact input, spring, screw rod, shank, nut, packing ring, epoxy, lead wire and form. When the stator break pin is cut, the rupture of screw rod atress, the spring will move contact input and pop out the screw contact of covering with the contact, the junction closure, the signal is seen off through the lead wire. The utility model discloses can realize the on -line monitoring of break pin state to can see state information off hydraulic turbine machine hole, send unit monitored control system to, can realize the automatic control of unit accident attitude, and make things convenient for timely, the quick inspection fault point of operation personnel. 本实用新型涉及种水轮机用剪断销状态在线监测元件，由接点盖、O型橡胶密封圈、动接点片、弹簧、螺杆、销体、螺母、垫圈、环氧树脂、引线组成。在导叶剪断销剪断时，螺杆受力折断，弹簧将动接点片弹出与接点盖上的螺钉接触，接点闭合，信号通过引线送出。本实用新型能够实现剪断销状态的在线监测，并能将状态信息送出水轮机机坑，送到机组监控系统，可实现机组事故态的自动控制，且方便运行人员及时、快速的检查故障点。
