摘要
采用频域介电谱法对高压油纸套管进行了受潮状态诊断。通过在COMSOL中建立110k V油纸套管模型,求解不同频率下的介质损耗得到其频域介电谱,并分析了套管频域介电谱的差异。
The moisture condition of HV oil-paper bushing is diagnosed with the frequency domain spectroscopy method. The model of 110 k V oil-paper bushing is established with COMSOL. The FDS of dielectric loss under different frequencies is derived. The differences of FDS of bushing are analyzed.
