摘　　要：配电房中电容器柜内的电器元件运行时会发出热量,致使电容柜内温度升高。特别是当电容器柜内温度超出规定的上限温度时,会导致柜内配套设备热老化,严重时会发生热机穿,过热运行还会降低设备运行可靠性。本文利用Fluent仿真软件对电容器柜进行建模;对电容器柜内温度场分布情况进行温升仿真,分析不同位置的出风口对电容柜运行时散热的效果,确定最佳位置;讨论在相同进风总面积、相同数量不同形状的散热孔对柜体散热效果的影响;确定散热孔位置分布、最佳散热孔数量,从而确定最佳的散热方案。制作出实物模型,进行实物模型试验,验证仿真分析的准确性。The electrical components in capacitor cabinet in power distribution room will emit heat during operation,causing the rising of temperature in the capacitor cabinet.Especially when temperature inside the capacitor cabinet exceeds the specified upper limit temperature,it will lead to the thermal aging of the associated equipment in the cabinet and the thermal breakdown in serious cases.Overheat operation will also reduce operation reliability of the equipment.In this paper,the model for the capacitor panel is established by the fluent simulation software,the temperature rise simulation for the temperature field distribution in the capacitor panel is performed,the effect of air outlet at different positions to the heat dissipation of capacitor panel in operation is analyzed and the optimum position is defined.The influence of radiation hole with same total inlet air area,same number but different shapes on the heat dissipation result of capacitor panel.The position distribution of the heat dissipation hole and the number of optimum heat dissipation hole are defined,thus defining the best heat dissipation proposal.The model of the object is made and tested and the correction of the simulation analysis is verified.
