在汽车起动机的修理过程中,发现因绝缘电刷架搭铁而引起整流器台起动机烧坏的现象。绝缘电刷架之所以搭铁,主要是由于绝缘刷架下的绝缘胶木垫圈和胶木块周围粘满了油泥和电刷灰,使绝缘电阻降低,起动电流通过油污直接搭铁。在维 Repair process in the car starter and found that due to the insulation brush holder ground caused rectifier rectifier starter burn phenomenon. The reason why the insulated brush holder is grounded is that the insulation resistance is reduced and the starting current is directly grounded through the oil stains because the insulating bakelite washer under the insulating brush holder and the surrounding of the bakelite block are covered with sludge and brush ash.
