With the continuous expansion of application range of self-healing dry metallized film capacitor
its heat dissipation mode and internal temperature-rising have become important theoretical and engineering problems. In view of this
the heat flow distribution of heating body of overall heating and even heating of cicular element of capacitor is analyzed on the basis of the heating rule of the circular element of the DC-link capacitor. Furthermore
the thermal calculation model of the circular element is set up in combination with the principle of electro-thermal duality
and the thermal resistance calculation formula of a circular element is obtained through the integration of the differential cells. Finally
the correctness of the thermal calculation model of circular element is verified through the test
and the verification method of thermal calculation of circular element is proposed
which will provide theoretical and test reference for the heating of circular element of DC-link capacitor.
