变压器油老化介电特性的研究及分析

Study on Aging Characteristics of Transformer Oil Insulation

近年来,我国的高压直流输电线路得到了广泛应用,作为其中关键一环的换流变压器也逐渐受到关注。换流变压器在运行过程中容易受到温度和水分等因素的影响,导致其绝缘老化,最终会对高压直流输电线路的安全稳定运行造成不利影响。因此,对换流变压器的绝缘老化特性进行研究分析具有重要意义,本研究成果对后续换流变压器的绝缘老化特性研究提供了一定的理论依据。

In recent years,high voltage DC transmission lines in China have been widely used,and converter transformer,as one of the key links,has been paid more and more attention.The transformer is easy to be affected by temperature and water during operation,which leads to insulation aging,which will eventually have adverse effect on the safe and stable operation of HVDC transmission line.Therefore,it is of great significance to study and analyze the insulation aging characteristics of converter transformer.The research results of this paper provide some theoretical basis for the research on the insulation aging characteristics of the converter transformer.
