水轮发电机碳刷及滑环磨损分析与处理

Analysis and Treatment of Abrasion in Carbon Brush and Slip Ring in Hydro-turbine Generators

水轮发电机在运行过程中,经常会发生碳刷磨损过大、打火与滑环表面损伤等问题,这些均对水轮发电机组的安全稳定运行产生不良的影响。通过对造成碳刷和滑环磨损的各种原因分析,提出了多项具体的处理建议,取了得良好的效果。

In the operation of hydro-turbine generators, abrasion and sparking of the carbon brush, and surficial damage of the slip ring are frequently observed, which could seriously affect the safe possible reasons of these problems are analyzed. Treatment measures are then that the measures are effective. and stable operation of the units. Thus, proposed correspondingly. Practice shows
