Evaluation of Transformer Insulation Aging and Discussion on Fine Maintenance Technology Considering Environmental Factors and Operating Life
This paper comprehensively and deeply discusses the evaluation method and fine maintenance technology of transformer insulation aging considering environmental factors and operation years.By systematically studying the aging mechanism of transformer insulation,the comprehensive influence of environmental factors(such as temperature,humidity,pollution,etc.)and operating years on insulation performance is analyzed in detail.A variety of effective evaluation techniques and means are elaborated in detail,and a targeted and feasible refined maintenance strategy is innovatively put forward,aiming at improving the operation reliability of transformers,effectively prolonging their service life and providing a strong guarantee for the stable operation of power systems.
