Abstract

Every country in the modern era is focusing on industrialization as an instrument for continuous economic progress. The industries like petroleum, coal mines, petrochemical, paint, etc., where flammable gases, vapors, or explosive dust particles are available. Some few micro-joules energy is required to create an explosion in these hazardous areas, so safety is a primary concern for the safe operation of these industries. Electrical power is required to operate the machineries. The power is stepped up, stepped down and distributed by a transformer. It is needed to put all electrical components of electrical equipment within the robust enclosure which helps to prevent explosion and minimize electrical-related accidents in the hazardous area. In this paper, some design aspects and analysis of some parameters like maximum principal stress, total deformation and directional deformation on cover of enclosure/box of flameproof enclosure for dry type transformer through ANSYS software are described. These parameters also were measured at 1MPa applied stress after meshing on all designed compartments of flameproof transformer enclosure.
