【摘要】：针对现有的10 kV开关柜实心矩形铜母线进行了轻质化优化设计及其载流量分析。在不改变实心矩形铜母线外表面的情况下,利用打孔技术,设计了一种新型轻质化母线结构,以达到节省材料、减弱集肤效应以及载流量降低不大的目的。并应用ANSYS软件对新型轻质化铜母线的集肤效应和温度场进行仿真分析。仿真结果表明:新型轻质化铜母线集肤效应有所减小,温度场仿真结果较同规格实心矩形铜母线略高。同时,将同规格实心矩形铜母线和新型轻质化铜母线通以相同大小的电流进行温升试验,实验结果与仿真结果一致。因此,新型轻质化铜母线在节省了15%的材料的基础上,热性能达标,载流量变化不大,为新型轻质化铜母线替代实心铜母线的工程化应用提供技术支撑。
[Abstract]:The light weight optimization design and load current analysis of solid rectangular copper busbar for 10 kV switchgear are carried out. Without changing the external surface of solid rectangular copper busbar, a new light weight bus structure is designed by perforating technique to save material, reduce skin effect and reduce carrier flux. The skin effect and temperature field of the new light copper busbar are simulated by ANSYS software. The simulation results show that the skin effect of the new light copper busbar is reduced and the temperature field simulation results are slightly higher than those of the solid rectangular copper busbar of the same specification. At the same time, the same size solid rectangular copper busbar and the new lightweight copper bus are connected with the same size of current to carry out the temperature rise test. The experimental results are in agreement with the simulation results. Therefore, on the basis of saving 15% of the material, the new light copper busbar has reached the standard of thermal performance and little change of carrier current, which provides technical support for the engineering application of replacing solid copper busbar with new light weight copper busbar.
