摘要
电力变压器是电力系统的关键设备，也是处于发电厂和客户之间的重要纽带，其作用不仅仅是变电那么简单，甚至对电力系统稳定、持续、安全运行，以及电力系统的经济效益等有直接关系。所以，对电力变压器剩余寿命进行评估具有重要研究意义。基于此，文章首先对电力变压器寿命体系进行简单介绍，对生命组成单元、寿命特点、寿命状态信息进行分析，对电力变压器寿命的影响因素进行研究，对电力变压器剩余寿命评估进行探讨，以期对于电力变压器使用寿命的延长，以及电力变压器经济效益的提升，起到一定的理论指导意义。
Abstract
Power transformer is the key equipment of the power system, but also an important link in power plants and customers. Its role is not only transforming so simple, even the power system stable, sustained and safe operation of the power system as well as economic benefits, which are direct relationship. Therefore, the remaining life of the power transformer has an important signiifcance assessed. Based on this, ifrst power transformer life system for a brief introduction to life constituent units, life characteristics, life status information for analysis, study factors affecting electric power transformer life, power transformers residual life assessment were discussed, in order to extend the life and enhance the economic beneifts of power transformers. It plays a certain theoretical signiifcance.
