Containment of blast phenomena in underground electrical power plants
Gas explosion accidents in electrical power plants can be originated by electrical faults in components containing oil for insulation, such as transformers, junction boxes, etc. A ground discharge can cause the pyrolysis of part of the oil and the production of a gaseous mixture, which can generate fires or deflagrations in contact with air. A deflagration gives rise to a pressure shock wave, which can propagate throughout the underground plant if not suitably confined. Fluid dynamic, structural and, in some cases, fluid structure interaction analyses are needed to evaluate the overpressures occurring during the blast phenomena and the consequent damages on structural elements. A numerical approach to this kind of problem is proposed and applied to a case study dealing with a typical transformer cell in an underground power plant. The fluid structure interaction code PLEXIS 3C is used to perform both fluid and structural fast dynamic computation.
