西津水电厂~#2发电机自1966年投产以来,先后暴露出设备制造上存在的许多严重问题,如定子线棒温度过高,定子铁芯温度分布很不均匀,下机架处回风现象严重,空气冷却器效果较差等。由于这些缺陷,致使发电机绝缘强度不断下降,对机组安全满发影响很大。几年来,西津水电厂也曾对这台发电机的通风系统作过一 Since the commissioning of Xijin Hydropower Plant ~ # 2 generator in 1966, many serious problems in equipment manufacturing have been exposed. For example, the stator bar temperature is too high, the temperature distribution in the stator core is very uneven, the return air phenomenon at the lower frame Serious, poor air cooler and so on. Due to these defects, resulting in a continuous decline in the insulation strength of the generator, a great impact on the safety of the unit. In the past few years, Xijin Hydropower Plant had also made a comment on the ventilation system of this generator
