摘要

为了研究电缆绕组变压器的暂态特性

笔者通过对无外金属屏蔽及护套的XLPE电缆绕组芯线加模拟雷电冲击电压

对外半导电层是否接电阻接地两种情况进行试验

得出了外半导电层接小电阻接地对芯线电压振荡有一定抑制及外皮电压最大值虽有一定的提高但震荡消失

有益于改善暂态特性的结论。

Abstract

The responses of XLPE cable windings without metal shield to lightning impulses were tested.It is found that the outer semiconducting layer grounding with a small resistance results in certain suppression on cable core surge

although the maximum voltage of the outer semiconducting layer elevates a little yet its oscillation disappears

which benefits the transient characteristic of the XLPE cable winding.
