PROCESS FOR CONTROLLING DRYER CAPABLE OF DEHUMIDIFYING AIR ENTERING THE OIL EXPANSION VESSELS USED IN ELECTRICAL APPLIANCES

摘要

Process for controlling a dryer (10), suitable of dehumidifying air entering oil expansion vessels used in electrical appliances, in which a protective casing of the dryer (10) surrounds at least two dehumidifying tanks or vessels (S1, S2) containing means suitable to absorb air humidity coming from the outside and which can be thermally regenerated by resistors (R1, R2); the resistors (R1, R2) are connected with a load cell (C1), suitable to determine the state of saturation of the absorption means, so that detecting by the load cell (C1) of a measured mass value (M) greater than a predefined threshold value (MFS) operates the resistors (R1, R2) in order to regenerate the absorption means to the original state.
