摘要： The invention relates to a device including a vessel, a vacuum pump (10), at least one condenser (3 and/or 8) and a heat exchanger (16) for heating and drying parts (2) with cellulose or plastic based hygroscopic insulation in transformers, condensers, instrument transformers or electric leadthroughs by means of condensation heat from the steam of a heating fluid (a solvent, kerosine). During heating, at least one higher-boiling second liquid, such as transformer oil, is removed. In order to provide a mobile system enabling local treatment of transformers (2) which are already in operation, the heat exchanger (16) heats the heating fluid in the liquid phase and evaporation occurs near to or in the vessel, for example, via expansion valves (18) and/or in an expansion container or evaporator arranged directly on the vessel.

摘要： Metals and/or metallic compounds are condensed from a vapor in a reaction vessel into a condenser, the condensate initially solidifying to block an outlet at the bottom of condenser; subsequent operation of heating stages from the top to the bottom of the condenser to melt the solidified condensate ensures that, as the outlet becomes unblocked, the whole melt flows into a mould.

摘要： Apparatus for heating and drying articles including an evacuable drying chamber for heating therein articles by condensation heat of the vapor of a first liquid supplied to the drying chamber, a vacuum pump for evacuating the boiler, a first vapor condenser and a second vapor condenser connected betwen the drying chamber and the vacuum pump, a thin film evaporator for receiving condensate from the drying chamber in the form of the first liquid and a second liquid having a higher boiling point than the first liquid, the second liquid being obtained from the articles within the drying chamber, a condensate collecting container for receiving from the evaporator liquid condensate which is not evaporated in the evaporator, a pressure barrier arranged between the evaporator and the collecting container and a re-evaporator arranged between the pressure barrier and the collecting container. The re-evaporator operates to lower the residual concentration of the first liquid and it is connected to the second vapor condenser thereby to reduce the residual concentration of the first liquid to a value corresponding to the vapor pressure in the second vapor condenser.

摘要： Equipment provides more rapid drying of heating parts comprising hygroscopic, electric insulation made of cellulose and/or plastics. At least two condensers are present, one being used when heating the parts and the other in the distillation stage. As a result removal by distillation is possible any time during heating and during the time intervals when heating is interrupted and the pressure-dropping procedure is carried out in the vacuum vessel. Due to the second condenser (with a second, associated vacuum pump), the heating medium can be cleansed or distilled during the pressure-dropping procedure and simultaneously the suction or drying procedure can be carried out in the vacuum vessel. This feature leads to drying the electrical parts more rapidly than heretofore because the steps of drying the electrical parts and regenerating the heating medium no longer require being consecutive, but instead regeneration can be implemented simultaneously with the evacuation of the vicinity around the electrical parts. By using a two-condenser design and different connecting lines, the versatility of the equipment is substantially increased. For instance the two condensers together with their associated vacuum pumps can be used in parallel for drying to achieve higher drying output and a higher operational rate. However, the two condensers may just as well be used to cleanse the heating medium; in this case they are separate from the vacuum chamber and cool only the heating medium heated by the evaporator and fed through the bypass line.
