Abstract :
In this article, an evaporative cooling circulation system for turbine generator stator winding was introduced. The design has taken into account of the characteristics of the whole liquid cooling approach for the large turbine generator, the requirements for the 50MW turbine generator evaporative cooling for the stator as well as the physical and chemical characteristics of the low boiling point high insulation fluorocarbon cooling medium. A experimental model circulation system according to the size of the 200-300MW turbine generator stator and winding was assembled for the testing. The testing results demonstrated that the design can meet the requirements for the large turbine generator stator winding inner cooling. In the article, the importance of configuring the circulation system, the essential of system structure as well as the test running results were given.
