description: This bachelor work is dedicated to the development and calculation of the thermal regime of a dry-type transformer with cast-resin insulation of a closed transformer substation 10/0.4 kV in order to avoid destruction of the insulation due to overheating. Its relevance is due to frequent cases of the destructive effect of thermal energy emitted by the transformer on its insulation, and as a result, emergency situations arising at a closed transformer substation. The aim of the work was to find the cause of the destruction of the transformer insulation in a closed transformer substation, taking into account its load and ambient temperature, as well as finding solutions to eliminate it on the example of a dry-type power transformer TLS-63/10. The study examined the design of a dry-type transformer and cooling system, analyzed modern research in the field of thermal analysis of transformers, estimated and selected methods of thermal calculation, developed the geometry of a closed transformer substation, carried out mathematical modeling of the temperature increase in the transformer and in the closed transformer substation taking into account the work of ventilation. Received data mapped with practical tests. The results of this study can be used by manufacturers of transformers and closed transformer substations to avoid subsequent overheating and increase its service life.
