'AN IMPROVED PROCESS FOR RESTORING DIMENSIONAL DEVIATIONS OF A BAKING WAGON USED FOR MANUFACTURE OF HV INSULATION ON STATOR BARS FOR TURBO GENERATORS'

摘要

The invention relates to an improved process for restoring dimensional deviations of a Baking wagon used for manufacture of HV Insulation on stator bars for Turbo generators, the baking wagon comprising at least three identical channels parallely disposed, and having associated toolings in the form of a side plank (2), an upper plank (4), a pressing plate (5) and a pressing rule assembly, the baking wagon enabling pressing of impregnated stator bars (3) into said channels by using the toolings, the process comprising the steps of: reducing the height of a middle piece (7) of the pressing rule assembly width, the pressing rule assembly further having right and left pieces (6, 8); increasing the width of the pressing plate (5) corresponding to the magnitude of decrease in the height of the middle piece (7), wherein the reduction in the height of the middle piece (5) is selected to compensate the increase in width of the baking wagon"s channel developed due to long use.
