| 摘 要： | 回复电压测量方法能有效检测变压器固体绝缘的含水量,然而对于含有局部峰值点的回复电压极化谱,难以给出明确的诊断结论.在引入扩展德拜模型基础上,建立了绝缘极化、老化过程和等值电路参数三者之间的关系,并仿真分析了电路参数的改变引起特征量和极化谱的变化规律.仿真分析结果表明,回复电压特征量的主时间常数能诊断不同几何电容的变压器...

| Abstract: | The return voltage measurement can effectively detect the moisture content of solid insulation intransformer,but it is difficult to get the definite diagnostic results from the return voltage polarizationspectrum with local peaks.The theory of extended Debye model is introduced,the relationship amonginsulation polarization,aging process and equivalent circuit parameter is established,and the variation law ofcharacteristic variables and polarization spectrum induced by the variation of electric parameters ar... |
