MANUFACTURING TECHNOLOGY winding insulation of traction motors

摘要

1. A method for impregnating the armature winding insulation, comprising applying to the coil stekloslyudosoderzhaschih ribbons, packing coils in the slots of the armature iron steklobandazha deposition, heating of the armature to the impregnation temperature, the impregnation evacuation in boiler feed under vacuum compound, for creating air overpressure compound surface, characterized in that, in order to improve electrical insulation properties and water and moisture resistance of the windings of traction motors, the supply pressure is carried out gradually to 6-8 bar in those chenie least 15 min.2. A method according to claim 1, characterized in that the impregnating compound is fed at room temperature.
