摘　　要：回复电压法作为一种无损诊断技术,因具有携带信息量丰富、抗干扰能力强等优点而被广泛研究,其试验结果可有效地反映变压器油纸绝缘的状况。为了实时地监控变压器绝缘状态以及合理地运行维护变压器,在研究影响回复电压特征参数因素的基础上,设计了一种基于回复电压法的变压器油纸绝缘专家评估系统,并利用专家评估法进行打分判断,使变压器绝缘状态能更清晰直观地呈现,具有一定的参考性。As a non-destructive diagnostic technique,the recovery voltage method has been widely studied due to its advantages of rich information and strong anti-interference ability.The test results can effectively reflect the condition of transformer oil-paper insulation.In order to monitor the transformer insulation state in real time and operate and maintain the transformer reasonably,an expert evaluation system of transformer oil-paper insulation based on the recovery voltage method is designed on the basis of studying the factors affecting the characteristic parameters of the recovery voltage in this paper.The expert evaluation method is then used for scoring and judging.Therefore,the insulation state of the transformer can be presented more clearly and intuitively,which can provide a certain reference.
