摘要
在现有的开关柜实心型母线的基础上,利用穿孔技术,设计了一种新型的孔洞型母线。孔洞型母线能够有效减弱集肤效应,并且达到了节省铜用量的目的。在有限元分析软件COMSOL中对母线进行建模,利用电流与温度场耦合的方法,分析比较了实心型母线和孔洞型母线的温升,得出了孔洞型母线能够有效减小温升的结论。理论分析与仿真分析均表明,文章所设计的孔洞型母线性能优良,可以在实际工程中推广应用。
On the basis of the existing solid bus-bar in switchgear, a hole-type bus-bar is designed by perforating technique. The hole-type bus-bar is able to reduce skin effect as well as saving copper consumption. The bus-bar model is made in COMSOL, the temperature rise of solid bus-bar and hole-style bus-bar is analyzed and compared by current and temperature field coupling method. The conclusion that hole-type bus-bar can reduce temperature rise is made. Through theoretical analysis and simulation analysis, the designed hole-type bus-bar has good performance to be applied in practical engineering.
