| 摘 要： | 利用有限元方法建立大电流开关柜母排的三维涡流场——温度场耦合分析模型,计算三维涡流场,得到磁感应强度和焦耳损耗的大小及分布规律;将焦耳热作为热源,通过顺序耦合方式计算出母排的温度场分布情况.实验结果验证了计算模型的准确性.在此基础上深入探讨不同工作电流对母排产生的温度场的变化规律,对设计大电流开关柜有参考价值.

| Abstract: | A 3D indirect coupled Finite Element Analysis(FEA) model of the coupled eddy current-thermal field is established for heavy current bus bar in switch cabinet.The eddy current field is calculated firstly,the distribution characters of magnetic flux density and joule heat is obtained.Then the thermal field distribution is calculated with the decentralized joule heat as heat sources.Experiments results verify that the FEA model is correct.The influence law of the operating current on thermal field is also stud... |
