摘　　要：以220kV油纸电容式套管为研究对象,提出了一种温度场数值计算方法,基于套管运行时的多种热源计算损耗,将所求损耗加载到温度场中,求解套管的温度分布以及热点,并在此基础上研究不同电流与温度的关系。Taking 220 kV oil-paper capacitive bushing as the research object, a numerical calculation method of temperature field is proposed. Based on various heat sources during the bushing operation, the loss is calculated, and loaded into the temperature field, and the temperature distribution and hot spots of the bushing are solved. The relationship between different current and temperature is studied on this basis.
