摘要

本文第一部分介绍了变压器结构(绕组、抽头和铁心)的诊断方法理论。文章的第二部分采用冲击试验和频响分析方法对变压器绕组故障进行了实验分析。冲击试验法和SFRA法在时域和频域上的测量对变压器绕组质量的诊断和分析具有重要意义。用相对因子Rxy的值分析了实测频率曲线之间的差异

Diagnostics of Difference Parameters of Transformer Winding in Time and Frequency Domain

In the 1-st part of article is presented theory about diagnostic methods for transformer construction (winding, taps and feromagnetic core). In the 2-nd part of article is presented experimental analysis of fault in winding of transformer by means of method of impact test and frequency response analysis (SFRA). For transformer diagnostics and analysis of winding quality are very important these methods by measurement in time and frequency domain using by impact test and method SFRA. Differences between measured frequency curves are analyzed by value of relative factor Rxy
