Abstract (en)
[origin: EP2525178A1] Water, contaminated impregnating and active portion of housing device after evacuation of housing is heated by condensation of solvent vapor which is formed by vaporizing solvent within and/or outside of housing. A mixed vapor flow is formed during heating, and water and solvent are separated. The heated active portion is dried under vacuum pressure, solid isolation of active portion is cooled and reheated by spraying heated spray oil on the surfaces of solid insulation. Thus, method for drying solid isolation containing active portion of electronic device is enabled. An independent claim is included for device.
