摘　　要：在简化开关柜内母线室模型的基础上,利用ANSYS并结合有限元的思想对其内部电磁场进行分析,结果表明同一相母线,母线弯角处的电场和磁场最大;不同相母线,中间母线的磁场最大。并比较了几种实时在线故障检测装置,得出应用红外窗口实现封闭式开关柜实时在线故障检测的可行性并确定红外窗口的安装位置。The model of the bus switch cabinet room in switchgear was simplified,and then the internal electromagnetic field was studied by ANSYS combining with the idea of the finite element.The results show that electric intensity and magnetic intensity at the corners of rectangular phase line reaches their maximum valises,while the electromagnetic intensity is the highest one in intermediate bus.Finally,the feasibility was verified that infrared window used for the real-time online fault measurement of the enclosed switchgear and determine the installation location of the infrared window by comparing several real-time online fault detection device.
