【Abstract】 The paper introduces the course that the electric machine of Y1250-12 type circulating water pumps for 130MW unit circulating water system’s improvement of variable-pole speed governing, and has changed into 12/14, 12/16, two-speed one has carried out. According to the situation of operation, the different pole of electric machine has been Combined flexible, and it has obtained the obvious energy-conserving result.更多还原
