一起上导油槽油混水原因的分析与处理

Analysis and Treatment of a Water Induction Fault of the Upper Guide Oil Groove

针对上通坝电站1号机组发生的一起上导油槽油混水事故,通过查找事故前后数据,对相关设备进行检查,发现是油流冲击致使油冷却器铜管与固定钢板间碰撞破损导致漏水,进而引发油混水,油冷却器结构设计问题是导致油混水的根本原因,经采取相应的处理措施,保证了电站的正常运行。

A water induction fault of the upper guide oil groove is observed in the No.1 unit in Shangtongba Hydropower Station.Through a detailed examination of the operation data before and after the fault,and the inspection of relevant equipment,it is found that the impact of the oil flow leads to the collision between the oil cooler copper tube and the fixed steel plate and causes water leakage,which finally results in the water induction into the oil.The inappropriate design of the oil cooler structure is the basic reason of the water induction problem.Then,corresponding treatment measures are implemented and the normal operation of the station is ensured.
