<p>PURPOSE:To prevent the degradation of oil and to extend the life of an oil charged transformer, by adding the deoxidizing function to an adsorbing device provided in a pressure adjusting part of the oil charged transfomer. CONSTITUTION:When the operation temperature of a transformer 1 drops, the volume of oil is reduced, and therefore, the internal pressure is lowered, and a rubber bag 21 is contracted, and air is sucked in the direction of an arrow A. This air passes through a deoxidizer 311 first and passes through a dehumidifier 322 next to become a gas consisting of only nitrogen. When the operation temperature of the transformer 1 rises, the volume of oil is increased, and said sucked nitrogen is pushed out, and this gas is returned to the layer of the deoxidizer 311 through a circulating flow passage 34. Thus, the degradation due to oxidation of the rubber bag 21 is prevented to prevent oxygen from being leaked from the rubber bag 21, and consequently, the degradation of oil is prevented to extend the life of apparatus.</p> |
