原4米~3电铲高压聚电环的结构如图所示。这种结构由于铸铁铁刷3与刷座5的弹簧定位杆之间的间隙小,由干电铲环轨磨损或其它原因引起回转平台与底架之间的距离小于421毫米时,使得铁刷和刷座弹簧定位杆相接触,刷座受过大的压力,使瓷瓶6(有时是瓷瓶1)
The original 4 m ~ 3 shovel high-voltage poly ring structure as shown. This structure due to cast iron brush 3 and the brush holder 5 spring positioning rod gap between the small, by the dry shovel ring rail wear or other reasons caused the distance between the rotary platform and the chassis is less than 421 mm, making the iron brush And brush holder spring positioning rod contact, brush seat subject to excessive pressure, so that porcelain 6 (sometimes porcelain 1)
