Abstract To obtain the temperature distributions on the shell and in the core of high voltage film capacitors in the thermal stability test,a thermal field model for high voltage film capacitors is formulated in Fluent 15.0 and solved based on the finite volume method.The results reveal that the side surface is higher than other surfaces on the shell and the hottest spot on the capacitor shell is located on the side surface.The hottest spot in the entire capacitor is located on the central axis of the capacitor close to the tail part.The temperature distributions on the capacitor shell are non-uniform.Because of complexity of capacitor structure,the temperature does not always increase/decrease monotonically.And there are several local hot spots.A fiber grating capacitor temperature monitoring system and an infrared thermal imager are used to measure the temperatures of some key points on the shell and in the interior of a high voltage film capacitor respectively in the thermal stability test.The measured results are qualitatively and quantitatively consistent with the simulated results.

Key words： High voltage film capacitor thermal stability test thermal field computational fluid dynamics infrared imaging
