发电机定转子绝缘低的原因分析及处理

Cause Analysis and Treatment of Low insulation of Generator Stator and Rotor

介绍了在极端潮湿的天气下,对于日启夜停的调峰机组,提出导致发电机绝缘电阻值降低的原因,分别对发电机定转子绝缘性能进行分析,提出关键部件的技术改造方案,有效地提高发电机定转子的绝缘水平,保证机组的安全、稳定、经济运行。

The reasons for reducing the insulation resistance of the generator in the extreme humid weather were introduced, especially for the daily start-stop peak-regulating unit. The insulation performance of the stator and rotor of the generator were analyzed, the technical transformation scheme of the key components was proposed, which effectively improves the insulation level of the stator and rotor of the generator, and ensures the safety, stability and economic operation of the generator unit.
