摘要

波纹铝护套由于具有良好的弯曲性能而被广泛用于高压交联聚乙烯（XLPE）绝缘电缆。然而，近年来发生了多起由缓冲层开始电缆烧蚀故障，严重的会发展到绝缘屏蔽层乃至于绝缘层。文中就径向电场引起的绝缘屏蔽的烧蚀机理展开研究，通过对不同间隙下绝缘屏蔽进行放电实验模拟，推导绝缘屏蔽烧蚀机理。实验结果表明，缓冲层发生烧蚀后会向内发展导致绝缘屏蔽烧蚀。有间距的情况下发生的击穿是缓冲层和绝缘屏蔽样品与电极之间的空气击穿，无间距的情况下，发生击穿是电极直接击穿缓冲层进而导致的绝缘屏蔽烧蚀。缓冲层的烧蚀会极大地影响绝缘屏蔽的电学性能。因此，应当重点关注铝护套波谷与缓冲层相接触点处引发的烧蚀故障，有利于防止电缆发生故障以及保障电网安全稳定运行。

Abstract

Corrugated aluminum sheath is used widely in high-voltage cross-linked polyethylene (XLPE) insulated cable due to its excellent bending performance. However

in recent years

there have been many cable ablation failures from the buffer layer

which will seriously develop to the insulation shield layer and even the insulation layer. In this paper the ablation mechanism of insulation shield due to radial electric field is studied. The ablation mechanism of insulation shield is deduced by simulating the discharge of insulation shield in different gaps. The experimental results show that the buffer layer will develop inward after ablation

resulting in insulation shield ablation. The breakdown

in the case of spacing

is the air breakdown between the buffer layer and the insulation shield sample as well as the electrode. While

in the case of no spacing

the breakdown is the insulation shield ablation caused by the electrode directly penetrating the buffer layer. The ablation of the buffer layer will greatly affect the electrical performance of the insulation shield. It is therefore necessary to focus on the ablation faults at the contact point between the aluminum sheath and the buffer layer

which is conducive to preventing cable failure and ensuring safe and stable operation of power grid.
