Abstract
An electrical equipment containment is arranged on a cooling enclosure opening out onto the outside. An outlet orifice makes the containment communicate with the cooling enclosure. This orifice is closed by a membrane or a check valve. A grate separates the cooling enclosure into an upper volume and a lower volume. The grate supports a layer of solid granular material the upper surface whereof remains free. This material is preferably porous and also comprises dusts. In the event of an internal electric arc, the shock wave escaping from the containment is dampened by the surface deformation of the layer of solid material. The incandescent particles projected via the opening are stopped by the layer of solid material. The hot gases are cooled as they flow through the material, causing a cloud of dust contributing to preventing any post-combustion.
