Since a switchgear accident can cause huge damage to property and human life, the stability and reliability of the switchgear are very important in the design of the switchgear. Above all, a short-circuit accident may be caused by an external factor, and lead to structural destruction and human life damage due to the short-circuit electromagnetic force. Busbars, supports and insulating structures in the switchgear must be designed to withstand these short-circuit characteristics which be changed by the current and the structure of the busbar. In this paper, an analysis model was developed to evaluate the effect of the volume force distribution of busbars obtained through electromagnetic field analysis on the DC switchgear structure.
