Abstract

For obtaining the temperature field distribution in the high-voltage all-film capacitor at the operation condition of 1.2 times rated voltage and ambient temperature of 55 °C

in this paper

the internal structure of the high voltage all-film capacitor is analyzed

the simulation model of three-dimensional temperature field of high-voltage all-film capacitor is set up and solved based on ANSYS Fluent and the complete temperature field distribution of the high-voltage all-film capacitor is obtained. It is shown by the simulation result that the temperature rise gradually from top to the tail of the capacitor case

the case top temperature is higher than that the case bottom

and if the horizontal layout

the hottest point inside the core is concentrated on the tail section

and if vertical layout

concentrated on the middle section.
