Abstract
A method for increasing the dielectric withstand strength in the enclosure E of an electrical apparatus, this method consisting in placing in the enclosure a dielectric material in liquid or solid form, then in bringing this material to a temperature and/or a pressure allowing for its total or partial evaporation in the enclosure. This method includes a device for retaining the abovementioned material in its container during the handling allowing the placement of the container in the enclosure E, and a device for inducing the evaporation of this material at a certain moment after this placement in the enclosure E and for allowing the dispersion of the gases resulting from this evaporation in the enclosure E.
