摘　　要：将ANSYS有限元热分析应用到交流接触器热特性分析中,模仿其实际工作环境,构建交流接触器三维稳态热分析模型,确定热源、导热系数和表面散热系数,对接触器的稳态温度场进行分析;进一步改变施加的边界条件,研究不同散热方式下接触器的温度分布。最后对CJX2-0910型交流接触器进行温升试验,将温度场的仿真结果与试验结果比较,误差较小,表明所建立热分析模型的可行性。研究结果对接触器材料的选择、结构的设计及其性能的优化有重要意义。The thermal analysis of finite element software ANSYS is applied to analysis the thermal characteristics of AC contactor.A thermal analysis model is established through imitating its working environment.After the heat source,thermal conductivity and coefficient of heat transfer are determined,the steady temperature field is analyzed.The change of boundary conditions can accomplish the analysis of different heat dispatch ways.Finally,temperature rise test is carried out,taking CJX2-0910 AC contactor as example.Compared the test results with simulation ones,the error is small,which shows the feasibility of the thermal analysis model.The result has great influence to materials selection,structure design and performance optimization.
