Abstract

Abstract

Internal short-circuit arcing explosion in a medium-voltage (MV) switchgear poses a serious hazard to the safety of equipments, buildings and personnel. In the present work, to find out an appropriate method to calculate the pressure effect resulting from the internal arcing explosion, we analyzed the energy balance mechanism of the internal arcing in the switchgear, presented an indirect coupling analysis method based on CFD through the analysis of the thermal-mechanical effect of the arcing process, and verified the method by the actual arcing in a closed container. The results show that the relative error of the average pressure rise between measurement and calculation is about 2%. The arc size has less effect on the pressure rise. In the closed container, the pressure rise approximately increases linearly with the increase of the arc energy. The installation of a negative pressure room can reduce the pressure in the arcing room 60%, thereby effectively restraining the pressure rise in the switchgear caused by the internal short-circuit arcing explosion.
