The development of intelligent dehydrate device for oil immersed transformer insulation system

Abstract

Abstract The transformer is the core equipment in the substation. The lifecycle and health of transformer will directly affect the reliability of substation, but the lifecycle of transformer depends on the oil-paper insulation status. Water, oxygen and temperature are the three factors that affect the performance of oil-paper insulation. The most important factor is the water. This paper designed an intelligent and safe dehydrating device based on the molecular sieve adsorption principle which can realize the on-line drying of transformer.
