基于热点温度分析的配电变压器老化评价方法

Research on Aging Evaluation Method Based on Hot Spot Temperature Analysis for Distribution Transformer

针对当前配电变压器检试信息相对匮乏的问题,本文引入热点温度模型,结合Arrhenius温度计算公式计算绝缘纸的等效绝缘损耗,提出了一种基于热点温度的配电变压器老化评价方法。该方法为解决量大面广的配电变压器健康诊断量化分析提供了一种解决方案。

Taking the relatively scanty detection and test information into consideration, a aging evaluation method for distribution transformer is proposed. It combines the hot spot temperature （HST） model and Arrhenius temperature formula to reach the equal insulation loss. As a result, this paper provides a feasible solution for health diagnosis quantitative analysis of distribution transformer, which is relatively vast and scattered abroad.
