Abstract[English]
An electrical machine includes an enclosure that features a plurality of assembly joints. An ignition source ignites a reactant mixture distributed within the enclosure to cause a flame to propagate from inside the enclosure to outside the enclosure through one or more flame paths. The one or more flame paths are formed along the plurality of assembly joints, where one or more porous linings are positioned along the one or more flame paths, and where the one or more porous linings within the one or more flame paths cool down and reduce a flow rate of the flame as the flame propagates through the one or more flame paths.[French]
Une machine électrique présente un boîtier qui comprend une pluralité de joints d'assemblage. Une source d'allumage allume un mélange réactif distribué à l'intérieur du boîtier pour provoquer la propagation d'une flamme depuis l'intérieur du boîtier vers l'extérieur du boîtier à travers un ou plusieurs trajets de flamme. Le ou les trajets de flamme sont formés le long de la pluralité de joints d'assemblage, un ou plusieurs revêtements poreux étant positionnés le long du ou des trajets de flamme, et le ou les revêtements poreux à l'intérieur du ou des trajets de flamme refroidissent et réduisent un débit de la flamme lorsque la flamme se propage à travers le ou les trajets de flamme.
