2×150MW generator ends winding loose and corona treatment

Abstract

Abstract:

Abstract:Panzhihua Power Plant 2×150 MW generator stator winding end part bearing fixing structure,lashing rope and a support ring and
supporting plate loosening effect,stator winding surface potential distribution is not uniform,in the high voltage,resulting in the big local potential gradient winding end part fixed and banding of tip and burr discharge phenomenon.In order to improve the life safety operation of generator, generator stator end winding were processed,and used the Harbin motor factory research obtains the reliable anti corona technology and anti corona treatment experience of winding of corona treatment,to take measures and through long-term monitoring on line partial discharge monitoring of generator stator winding insulation,can timely evaluation the state of generator stator winding fault,found early signs of early,to avoid the occurrence of accidents.After four years of operation,has achieved remarkable results.
