Abstract

Abstract: In the operation of turbogenerator set, the overheat phenomenon of stator bar was happened occasionally. According to the water flow test, it is decided that the main reasons of higher temperature of the generator stator bar are the corrosion of stator bar and water tube blockage by foreign body, which causes the water path to be narrow and the flow velocity of stator cooling water to be slowly. After the bar had been purged by water hammer, the water flow is not exceeding the average by ±10% and is accordance with evaluation requirement. Finally, the concrete measures for prevention of generator stator bar corrosion were given. 
