METHOD FOR INCREASING THE DIELECTRIC WITHSTAND STRENGTH IN AN ELECTRICAL APPARATUS, AND APPARATUS HAVING AN IMPROVED DIELECTRIC STRENGTH ACCORDING TO THIS METHOD

摘要

The present invention relates to a method for increasing the dielectric strength inside the enclosure E of an electrical apparatus, this method consisting in placing inside said enclosure a dielectric material in liquid or solid form, and then bringing this material at a temperature and / or a pressure allowing its total or partial evaporation inside the enclosure. This method is characterized in that it comprises means (8) for retaining said aforementioned material inside its container during handling allowing the introduction of said container in the enclosure E, and means (9) for evaporation of this material at a certain time after this establishment in the enclosure E and to allow the dispersion of the gases resulting from this evaporation inside the enclosure E.
