Embodiment Construction
[0017] The present invention is a method for manufacturing the lead wire insulation of the parallel connection ring of the stator of the all-hydrogen-cooled turbogenerator, which includes the following manufacturing steps:
[0018] a. Insulation material selection and wrapping process: Use a universal wrapping machine to enter the factory for wrapping, set the wrapping method of the universal wrapping machine to 1 / 2 overlapping winding, set the wrapping tension to 45N, fix the copper bar on the universal wrapping machine, and place the copper bar on the Brush 1 layer of adhesive on the surface, start the universal wrapping machine and wrap 25 layers of Tongma epoxy glass powder mica tape with a width of 25mm and a thickness of 0.14mm on the copper bar in a 1 / 2 overlapping wrapping method, and wrap Tongma epoxy glass For powder mica tape, brush 1 layer of adhesive on the outer surface after each layer is wrapped, and scrape off the excess adhesive on the insulating surface while...
