Estimating the term…
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.
A method for increasing the dielectric withstand strength inside the enclosure of an electrical apparatus, said method comprising:
The electrical apparatus according to claim 6, further comprising means for retaining said material inside its container, said means comprising an absorbent substrate filled with a dielectric liquid and a tight packaging capable of transporting said substrate and from which said substrate can be removed before being placed in the enclosure just before the closure of said enclosure.
The electrical apparatus according to claim 7, wherein the liquid is a fluorinated liquid.
The electrical apparatus according to claim 12, wherein it is a medium or high voltage electrical protection apparatus.
