Abstract

Improvements in electrical appliances equipped with compressed air dielectric, characterized by comprising a) A tank filled with dielectric air at a high operating pressure. b) Metallic elements and insulating elements inside said tank equipped with surfaces subjected to high electrical potentials comparatively with the potential of the internal surface of the tank. c) Means for releasing compressed air from the tank after operation of the internal electrical device, d) Means for replenishing compressed air in the tank, e) Means for limiting the relative humidity of the incoming air in the tank to a proportion less than fifty percent, f) A quantity of drying material placed inside the tank, characterized by transferring moisture absorbed to a gas that surrounds it when the pressure of the absorbed water vapor exceeds the partial pressure of the water in the gas. g) Said drying material is characterized in that its saturation at the room temperature is incomplete when the equilibrium of the relative humidity of the air surrounding the secant is maintained at the level of fifty percent. h) Said drying material is characterized by maintaining an approximately constant relative humidity between the temperatures of 30º F = 1,11º C and 200º F = 93,3º C, when its water content is fixed, i) The weight of the drying agent contained in the tank must be large enough so that the secant can absorb the maximum condensation contained in the air of the enclosure at its highest working pressure and with the highest operating equilibrium temperature of the electrical device internal, without more than a small percentage of increase in the weight of the secant. j) The surface of said drier exposed to the air inside the tank must be wide enough for the drier to absorb the water quickly enough to avoid the condensation of moisture on said surfaces subjected to high electrical potential even when the ambient temperature external to the tank falls in 50ºF = 28º centigrade approximately in the course of one hour.
