基于健康指数的电力变压器绝缘状态评估方法研究
Research on Insulation State Assessment Method of Power Transformer Based on Health Index
摘要
Abstract
In order to scientifically and reasonably assess the health level of power transformers in operation,a three-level assessment model,which is composed of ontology data,operating data and correction coefficient,is set up in accordance with the key characteristic information of transformer.The theory of health index is introduced to analyze the weight of different key characteristic information reflecting the insulation state of transformer,and the calculation method of health level of transformer three-level assessment model is proposed and,on this basis,the calculation for-mula of transformer residual life is obtained.Finally,it is proved in combination with an actual case that this method can scientifically and accurately assess the insulation state of power transformer in operation,and provide reference for engineers and technicians to assess the insulation state and residual life of transformer.关键词
