摘　　要：在发电机组检修过程中,滑环室发电机碳刷刷握需取下更换,并对滑环、导流环、正负极接头等一系列的检修工作,各个部件检修完成后回装。其中碳刷刷握回装时,刷握插入底座后需调整刷握与滑环的间距,要求为2~3 mm,防止间距过长或过短导致滑环打火、碳刷温度高等问题,为解决这一问题,设计了一种发电机新型碳刷刷握底座。During the maintenance process of the generator set,the carbon brush holder of the generator in the slip ring room needs to be removed and replaced,and a series of maintenance work should be carried out on the slip ring,guide ring,positive and negative pole joints,etc.After each component is repaired,it should be reinstalled.When reinstalling the carbon brush holder,the distance between the brush holder and the sliding ring needs to be adjusted after the brush holder is inserted into the base,with a requirement of 2-3 mm,to prevent problems such as sliding ring ignition and high carbon brush temperature caused by excessively long or short distance.To solve this problem,a new type of carbon brush holder base for generators has been designed.
