摘要
When a fault arc occurs in electric power equipment including insulation oil, it may cause damage to the equipment resulting from a rapid pressure rise, and lead to leakage and blowout of the oil and the generation of a high-temperature flammable pyrolysis gas. Therefore, we have examined these phenomena for an underwater arc from experimental and simulation aspects, as a preliminary step toward dealing with an arc in the oil. In this study, we have developed a pressure rise analysis method taking into account the thermodynamic behavior for the underwater arc by improving the previous work focused on the hydrodynamic behavior of gas-liquid two-phase flow, and verified the validity of the analysis method by comparing the experimental and simulation results. © 2016 The Institute of Electrical Engineers of Japan.
