Temperature is a key factor affecting performance and operation life of the capacitor. For obtaining the temperature field distribution inside the assembled shunt capacitor

in this paper

the internal structure and mechanism of heat generation and loss of the capacitor are analyzed. The threedimensional simulation model of the temperature field of the capacitor is set up in ANSYS Workbench15.0 and is solved by finite volume method（FVM）and the internal temperature filed distribution

shell temperature as well as the temperature and position of the hottest spot of the assembled shunt capacitor are obtained. The simulation result and method can provide reference for optimization design of radiation structure and control of the internal hottest spot temperature of the capacitor.
