Determination of temperature distribution on windings of oil transformer based on the laws of heat transfer

Object of research: development a technology for determining the temperature winding power oil transformer, in particular, analysis thermal processes transformer during short-term overloads, taking into account influence environment.
 Investigated problem: distribution load surges problem assessing residual life insulation by aging. The calculation was carried out using passport data and characteristics including winding, oil, currents.
 Main scientific results: mathematical model calculated, with help which results were obtained or constant work an increased load. According to presented model, cooling time after overloads is out. Comparing on simulation known experimental studies adequacy proved. It shown that use laws heat transfer homogeneous plate analyze not wrong, but requires clarifications simplifications.
