摘要: 由于刷握结构设计不合理,导致碳刷的有效使用量太少,使得发电机励磁碳刷日常维护量加大。通过对几家生产商的设计、安装和使用单位实际使用效果的调查比对,结合华电内蒙古能源有限公司包头发电分公司的试用状况,最终决定采用插拔式双卷可控刷分体恒压刷握的节能改造方案,取得了很好的节能效果。

Abstract: Due to that the structure of the brush holder is not designed rationally, the effective usable part of the carbon brush is very little, and the daily maintenance work of the generator excitation carbon brush increases. The design and installation of the carbon brush of several manufactures and the practical use effects in enduser site were investigated and compared. Combining with the trial use status of the carbon brush in Baotou Power Generation Branch of Huadian Inner Mongolia Energy Company Limited, an energysaving reformation scheme of the brush holder was selected finally, in which the plugin constant pressure brush holder with double controlled and detachable springs wasadopted. After the reformation, favorable energysaving effect was obtained.
