Research of evaporative cooling method for improving electric field of high voltage generator

• 摘要：

  In order to develop the first inland 24 kV rated voltage turbogenerator, this paper proposes to adopt an evaporative cooling method to realize it. According to the high insulation capability of evaporative cooling medium, this paper gives a new kind of stator insulation structure that is suitable to evaporative cooling mode and can be applied to high voltage level. By finite element method calculation software, this paper simulates the static electric fields in the slot and the end of a high voltage generator stator. Then this paper analyzes in detail the three-phase insulation system consisted of gas, liquid and solid formed by evaporative cooling mode, including the reliability of its anti-corona and anti-breakdown. After a series of researches on insulation characteristic and laws of the new structure, a conclusion that if the new insulation system is designed in reason it is feasible to 24 kV rated voltage, is obtained.
