摘　　要：随着经济社会发展与用电需求的剧增,大电流固体开关柜的研制成了当下热点。文中以某型大电流固体开关柜为对象,通过有限元仿真软件对其三维模型进行温度—流体场仿真研究。模拟分析采用不同导热率环氧树脂、优化散热风道前后的固体柜温升分布,并通过型式试验对比验证仿真方法的有效性。研究结果表明:固体柜发热部位集中在上转接头、动触头、T型导体、软连接及真空泡动静端,其中以真空泡动端温度最高。优化后的固体柜,柜内气流流速增强,发热点温升大幅降低。研究结果为大电流固体开关柜的研制提供新的方法和思路。With the development of economic society and increase of demand for electricity,the development of high current solid switchgear cabinet has become a hot topic at present.In this paper,a certain type of high current solid switchgear cabinet is taken as the research object,and the temperature-flow field of its three-dimensional model is simulated through the finite element simulation software.For the simulation analysis,the epoxy resin with different thermal conductivity is used,the temperature rise distribution of the solid switchgear cabinet before and after optimization of heat dissipation air duct is optimized and effectiveness of the simulation method is compared and verified through type test.The research result shows that the heating parts of the solid switchgear cabinet are concentrated in the upper adapter,moving contact,T-type conductor,flexible connection and the dynamic and static end of the vacuum bulb,in which the dynamic end of the vacuum bulb has the highest temperature.After the optimization of the solid switchgear cabinet,the airflow velocity in the cabinet is increased and the temperature rise of the heating spot is greatly reduced.The research results provide a new method and idea for the development of high current solid switchgear cabinet.
