The electrical components in capacitor cabinet in power distribution room will emit heat duringoperation

causing the rising of temperature in the capacitor cabinet. Especially when temperature insidethe capacitor cabinet exceeds the specified upper limit temperature

it will lead to the thermal aging of theassociated equipment in the cabinet and the thermal breakdown in serious cases. Overheat operation willalso reduce operation reliability of the equipment. In this paper

the model for the capacitor panel isestablished by the fluent simulation software

the temperature rise simulation for the temperature fielddistribution in the capacitor panel is performed

the effect of air outlet at different positions to the heatdissipation of capacitor panel in operation is analyzed and the optimum position is defined. The influence ofradiation hole with same total inlet air area

same number but different shapes on the heat dissipation resultof capacitor panel. The position distribution of the heat dissipation hole and the number of optimum heatdissipation hole are defined

thus defining the best heat dissipation proposal. The model of the object ismade and tested and the correction of the simulation analysis is verified.
