50WT23E-138发电机主要特点介绍
独立的轴承,可以避免将轴承振动传给定子机座，减少润滑油向机座内漏油的几率。 发电机转子只有励端一个大风扇,便于发电机转子的拆装。 悬挂式定子铁心，起到了对定子机座的很好减振的作用。 定子铁心端部采用的是与定子铁心材料相同的叠片式压板，极大地减少了铁心端部的损 耗，很好地控制了铁心端部温升，而不会发生过热，进相能力非常强,功率因数0.95(超 前)运行不受时间限制。 发电机定子端部具有再紧装置，保证定子线棒端部一直处于紧固状态。定子槽内也有再 紧设计，保证发电机运行过程中，定子线棒不会发生松动。 定子线棒采用的是TVPI真空压力浸。定子线棒绝缘的整体性能非常好，不容易被破坏, 同时热传导效果好, 有效地进行散热。 定子线棒空心导体是不锈钢材质的,杜绝了铜和氧发生反应产生二氧化铜而堵塞铜管的可 能性。 刷架部分采用的是封闭式空气循环系统，有空气过滤装置、湿度调节装置及空气冷却器 等对刷架装配运行的温度、湿度进行调解，同时保证空气的净化。 三流环密封油系统可以大大减少漏氢量。

50WT23E-138 Generator main characteristics
The separate bearings avoid to transfer vibration to stator housing. Lube oil can not leak in stator housing. There is only one main fan of generator rotor. It is convenient to install generator rotor in stator. The suspend stator core reduces vibration influence to stator housing. Laminated press plates at two sides of stator core that have same material as stator core reduces flux loss at two ends greatly. Temperature rise at end of stator core is controlled well. Leading phase operation ability is very high. Operation is not limited by time at leading power factor 0.95. There is re-tight device at end windings to ensure tight condition all the time during generator operation life. There is re-tight design in stator slots.It ensures the bars in slots are tightened during operation life. TVPI technology of stator bar manufacture guarantees stator bar insulation integrality and good heat conductivity. Stainless steel hollow conductor avoids to be clogged by CuO2 that cause copper hollow conductor clogging. Closed air cooling system with filter and humidity conditioner provides good operation conditions. Triple circuit sealing ring reduces hydrogen leakage greatly.
