摘　　要：为保证高压配电盒工作的可靠性和稳定性,需要对继电器温升是否超过极限做出判断,但设计阶段没有实际产品可以用于评估,因此通过有限元手段可以对高压配电盒充放电温度进行详细的分析研究。通过有限元数值模拟与实际实验进行对比,验证了高压配电盒模型整体的可靠性;给出高压配电盒内部零件的简化方法。仿真结果趋势与实际测点结果基本一致,不同测点最大误差在4.9%以内,证明了在前期研发设计中通过散热仿真来预判结构内部温度以及物料选用的可行性。研究结果致力于为同行业提供一种在设计阶段验证方案的方法。In order to ensure reliability and stability of the high voltage distribution box,it is necessary to judge whether the temperature rise of the relay exceeds the limit.However,there is no actual product in the design stage for evaluation.The charging and discharging temperature of the high voltage distribution box can be analyzed and studied in detail by the finite element method.In this paper,the reliability of the high voltage distribution box model is verified by comparing the finite element numerical simulation with the actual experiment.The simplified method of the internal parts of the high voltage distribution box is given.The trend of simulation results is basically consistent with the results of the actual measurement points,and the maximum error of different measurement points is within 4.9%,which proves the feasibility of predicting the internal temperature of the structure and material selection through heat dissipation simulation in the preliminary research and development design.The research in this paper is devoted to providing a method to verify the scheme in the design stage for the same industry.
