摘要
针对某厂600MW超临界机组1#机定冷水水中含油的问题进行了原因分析,确定了氢水差压开关被击穿损坏,造成密封油进入定冷水系统,造成定冷水水中含油。
For a 600MWsupercritical unit 1 machine for stator cold water in oil issues cause analysis to determine the hydrogen water differential pressure switch is breakdown damaged,causing seal oil enters the stator water cooling system, resulting in oil in water for stator cold water.
