Analysis and Experiment of the Pressure Rise in Switchgear of Arc Fault
Arc Fault에 의해 발생되는 배전반 내부의 압력변화에 대한 전산해석 및 실험적 연구
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.
