Loss and Heat Calculation of Oil Transformer Top Cover Near Bushings
Trombik, Šimon ; Toman, Marek (referee) ; Mrajca, Miroslav (advisor)
This bachelor's thesis deals with the calculation of losses on the cover of an oil transformer in the vicinity of LV bushings. This is because there is thermal stress and aging of the seal under the grommet and, subsequently, oil leakage. The production of oil transformer sub-parts is briefly described here, and the chapter is devoted to transformer grommets. Another part is also a literature search of eddy losses in the cover and container of the oil transformer. Subsequently, the preparation of the electromagnetic and thermal simulation is described here, where a lot of attention was paid to heat in particular.
