摘要

防火电容器作为一种新型电力电容器

非常有必要研究其热平衡问题。本文建立了防火电容器的热平衡数学模型

并分析了其热传导过程与现有并联电容器的差别。然后

通过热稳定试验研究了外壳散热面积和防火介质对防火电容器温升的影响。研究成果能为防火电容器的散热设计提供参考。

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.
