轻质型10kV开关柜母线设计及其载流量分析
针对现有的10kV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...

| Abstract_FL | Aiming at the current rectangular copper bus-bar of 10KV switchgear, lightening optimal designing of the bus-bar is conducted and its thermal performance is analyzed in this paper.Without changing the surface of the rec-tangular copper bus-bar,a new lightweight bus-bar is designing by punching on the cross section of rectangular bus-bar in order to save the material and reduce the skin effect.The skin effect and temperature field of new bus-bar are analyzed by ANSYS.The simulation results show that the skin effect of new lightweight bus-bar is significantly re-duced,and the simulation results of temperature field are slightly higher than that of the rectangular bus -bar.At the same time,electrify the rectangular bus-bar and the new lightweight bus-bar with same current and do the tempera-ture-rise test.The result of experiments is accordant with that of simulation.Therefore, the thermal performance of new lightweight bus-bar is up to the standard on the basis of saving as much as 15%of the material,which can pro-vide the technology support for re-placing the rectangular copper bus-bar in engineering. |
