Abstract:

Abstract:Since the pH value,electrical conductivity and copper content of stator cooling water in plant generator are abnormal,correspondent actions are taken;while,the initial effect is not obvious.After the shutdown and complete flushing of stator cooling water system,the problem is that the expander weld of stator cooling water anti siphon pipe is cracking as a result of large generator vibration.The problem is sorted out through re-welding.
