摘　　要：母线选型是低压开关柜设计过程中的重要内容,是否合理将直接关系供配电系统运行的安全、可靠性,在设计过程中要引起足够重视。以户内低压开关柜母线选型为例,从导体集肤效应、载流量、热稳定性及动稳定性方面对低压母线设计选型进行阐述,进一步明确了设计时的重点注意事项。The selection of busbars is an important content in the design process of low-voltage complete switchgear.Whether it is reasonable or not will directly affect the safety and reliability of the operation of the power supply and distribution system,and it should be paid enough attention in the design process.Taking the selection of indoor low-voltage switchgear busbars as an example,the design and selection of low-voltage busbars are expounded from the aspects of conductor skin effect,current carrying capacity,thermal stability and dynamic stability,and the key points for attention in design are further clarified.
