| 摘 要： | 近年来通过制造和运行实践，国内对控制发电机机内冷却体湿度的重要性的认识日益加深，汽轮发电机中冷却气体湿度过大对发生定子线圈绝缘故障，转子护环应力腐蚀有很大的影响。本文就冷却气体湿度标准，氢气干燥器的设计使用，湿度测量等有关问题，结合平圩６００ＭＷ发电机的运行经验进行探讨并提出解决措施，以提高发电机运行的可靠性。

| Abstract: | n recent years, importance to control of cooling gas moisture in turbogenerator is cognized further deep at home through manufacture and operation practice. Excessive moisture of cooling gas in turbogenerator have great influence on insulation fault of stator winding and stress corrosion of retaining ring.Combining with operation experience of 600 MW turbogenerators for Pingwei power station, conserned problems, such as moisture standard for cooling gas, design and application of hydrogen drier, measurement of moisture, etc.are studied, and measures solving them are presented to improve turbogenerator operation reliability. |
