汽轮发电机高速集电环国产电刷导线过热的原因及改进措施

CAUSES AND IMPROVING MEASURE OF SUPERHEAT-WIRE OF HOMEGROWN BRUSHES FOR HIGH SPEED COLLECTOR OF STEAM-TURBINE GENERATOR

分析了集电环电刷在运行中产生的导线过热变色 ,烧损的原因 ,介绍了集电环开螺旋槽和采用开口气孔率大的多孔电刷 。

The causes of changing colour and burning loss For superheat wire produced during the running Of collector brush are analyzed.The way of anti-superheat wire burnig loss was introduced by opening helical flute of a collector and using pore Brush with large opening prorosity.
