汽轮发电机定子直流泄漏及直流耐压试验

DC Leakage and DC Voltage Endurance Test of Turbogenerator Stator

大型汽轮发电机产品在出厂前及大修后,为考核定子端部线圈绝缘质量需做定子直流耐压及直流泄漏试验,本文介绍直流耐压及直流泄漏试验及试验结果分析。

Large turbogenerator requires stator DC leakage test and DC voltage endurance before leaving factory and after repairing, to examine the quality of stator end windings. This paper introduces the above tests and analyzes the test results.
