The carbon brush and collector ring are the equipment of dynamic and static contact and energy exchange of the generator.During the operation of the generator set,the carbon brush and collector ring often overheat in the long-term friction.If not handled in time,incidents of burning damages are likely to occur,which may seriously threaten safe operation of the generator set.Causes of the overheating phenomenon due to the friction of the carbon brush and collector ring during the operation of a generator set are analyzed in the aspects of the carbon brush,brush grip,collector ring,ventilation and brush holder,and corresponding technical measures are formulated,which have a remarkable effect on lowering the surface temperature of the carbon brush and collector ring.
