| Abstract: | As a new type of power capacitor,it is very necessary to study the heat balance of fireproof power capacitors.In this paper,the heat balance mathematical model of fireproof power capacitor is established,and the difference between its heat conduction and that of existing parallel capacitor is analyzed.Then,the influence of the heat dissipation area of outer casing and the fireproof medium on the temperature rise of fireproof power capacitor is studied by thermal stability test.The study results can provide reference for the heat dissipation design of fireproof power capacitors. |
