| 摘 要： | 为将回复电压法用于电力变压器绝缘老化状态的无损诊断,通过实验室加速热老化实验,研究了不同老化程度下油纸绝缘回复电压各参数(回复电压最大值、初始斜率、中心时间常数)的变化规律;考虑到水分对回复电压参数的影响,亦对比分析了老化油纸绝缘试品干燥处理前后回复电压参数的变化.在原有回复电压参数的基础上,提出了一种新的可用于评估油... |

| Abstract: | In order to obtain non-destructive diagnosis of the aging state of power transformer insulation by the recovery voltage method(RVM),the variation of the RVM parameters of oil-paper insulations with the aging degrees was investigated using the accelerated thermal aging and the recovery voltage method tests.On the basis of the effect of water on RVM parameters,RVM parameters of aged oil-paper samples before and after drying treatment were comparatively analyzed.A new RVM parameter,namely,relatively constant v... |
