DETAILS
Kerosene steam as the heat carrier medium can be conducted in a vacuum state convection heat transfer and condensation
heat relcase, the lower the temperature the more intense the condensation place, i.e., the larger the heat release, therefore
the body temperature is uniform. Kerosene vapor not only heat the insulating material by heat exchange, but also carry on
exothermic phase transsition condensate in the insulating material surface. Then, the condensed kerosene have a heat
exchange in the insulting film surface. Heat transfer efficiency is higher than any other heating methods, so the heating rate is fast.
Since the saturation pressure for the kerosene, the kerosene after completion of the heating can evaporate quickly,
without affection the diffusion coefficient of the high vacuum stage of the moisture within the material.
Heating is carried out underanaerobic conditions in a vacuum, so that the heating temperature may be increased from 0 ℃ to 130℃
without causing the aging of the insulation material, in which case water vapor paitial pressure is increased to about 98000Pa,
moisture inside the insulating material the diffusion coefficient increases, the water evaporates much faster. While the entire
drying porcess, the body has been in the vacuum state, the ater throughout the course of the drying cycle. And therefore,
can maximize the kerosene vapor drying efficiency, energy saving demand.
Condensed kerosene easily penetrate into the surface and inside the insulationg material, the insulating material itself
accelerated thermal conductivity, and the insulatiing material deep temperature distribute uniformly.
Condensation of kerosene as a good cleaning solvents, can wash off dirt on the transformer, it is the unique feature of
kerosene vapor drying. This feature is also the main reason that kerosene vapor is particularly suitable for treatment of
the repair transformers, the transformer body surface is clean and no grease and stains.
