| 摘 要： | 变压器分接开关出现故障甚至烧蚀时会影响变压器绕组的频率响应特性。利用频率响应分析法对某变压器进行绕组变形测试,分析了分接开关烧蚀对绕组变形测试结果的影响。在Matlab仿真平台上建立了分接开关烧蚀时的绕组等效模型,利用计算机仿真研究了分接开关烧蚀时在不同频率范围内对绕组变形结果的影响程度,为今后分析变压器绕组变形频率响应曲线提供了理论分析手段。

| Abstract: | The frequency response characteristic of transformer winding will be affected when faults,especially ablation,occur in tap changer of transformer.The winding distortion test is carried out using the frequency response analysis,and the influence of ablation of tap changer on winding distortion is analyzed.An equivalent model of winding in case of tap changer ablating is established by using Matlab.Simulation is also carried out to reveal the influence under various frequency ranges,and the results provide a theoretical means for winding distortion curve analysis. |
