Gaoya dianqi, 2016 文中以一种新型变压器绕组检测方法——扫频阻抗法为理论依据,建立了试验室测试系统,并利用该系统对单相双绕组变压器进行了测试。其结果表明:扫频阻抗法能够有效反映变压器绕组分布式参数,且其测试结果在频率大于11.5 k Hz时与频响曲线呈现轴对称关系;短路故障会造成50 Hz处阻抗值与相关系数皆发生变化,且故障越严重,阻抗值与相关系数的变化越明显。

Gaoya dianqi, 2019 针对干式空心电抗器匝间绝缘故障,采用磁矢位法对故障状态下空心电抗器电感量进行了分析。在分析过程中,考虑到故障线圈中环流所形成的磁场对干式空心电抗器电感量影响下,得出故障状态下干式空心电抗器电感量计算的精确解析表达式。在此基础上,利用电磁仿真软件MAGNET对干式空心电抗器磁场及故障线圈环流进行仿真分析,并对相同故障状态的电抗器进行不同频率下的电感量测量。由仿真和测试结果表明:故障线圈环流对干式空心电抗器电感量影响较大,其影响随着频率增大而增大,最终趋于稳定 ...
