摘要

FIELD: electrical equipment.;SUBSTANCE: invention relates to the electrical equipment. Traction transformer (TT) after impregnation is placed in a chamber with thermal insulation, in which pulsed ceramic medium-wave infra-red radiators are installed, collected in the panel. IR-emitters are located strictly in certain places over parts with high thermal inertia: above the magnetic circuit and on the sides of the steel case. Such an arrangement of IR emitters allows accelerating their heating with a high temperature of 300–400 °C due to the high flux density of IR radiation. Control over the heating of the insulation to prevent its overheating is carried out by thermal sensors. Effect of intense pulsed medium-wave infrared radiation on the steel parts of the TT makes it possible in a short time to heat them up to high temperatures without overheating the insulation. If the insulation temperature is reached at control points up to 105 °C (or other, depending on the type of insulation), the thermal sensors will send a signal to turn off the corresponding panel of IR emitters. Choice of control points for the heating temperature is due to the approximate isolation of the IR radiation. Upon reaching the set heating time, determined by the dimensions of the TT, it is immediately installed in a vacuum drying cabinet, where the main drying of the insulation is carried out with the holding of the required temperature. Due to the accelerated preheating of the TT parts with large thermal inertia, the total time of the drying process is significantly reduced.;EFFECT: technical result consists in reducing energy consumption and time for technological drying operations.;1 cl, 2 dwg
