Abstract

To develop and improve a switchgear, the prediction of the pressure rising within the switchgear is very important. This study investigates the pressure rising characteristics of switchgear in order to evaluate the result of arc fault test. The pressure rising time at the four points of measurement calculated by CFD is well accord with the experimental results. The maximum pressure within the switchgear estimated by CFD is about 1.0bar, the pressure from experiment is 0.7 bar. The results of this study are able to be used to improve the performance of existing switchgear and to develop a new type switchgear.
