【摘要】 通过对XLPE电缆变压器和传统变压器的绕组暂态特性试验的比较和分析 ,指出前者在雷电冲击电压作用下的外部端口特性与频率有关 ,波前时间内电缆绕组表现为一段波阻抗约为 2 10Ω的长线 ,波前时间后主要表现为其总的对地电容。为该种新型变压器的设计、保护及试验技术提供了依据。更多还原

【Abstract】 In this paper, according to experiment research and analysis of the responses of XLPE cable windings and traditional power transformer windings to the lightning impulses, the import characteristic of XLPE cable windings is obtained. It provides a theoretical basic for the design, protection and testing of this new type of power transformer.更多还原
