交联聚乙烯电力电缆的绝缘在线监测技术

Status quo and future development of the on-line monitoring technique for XLPE power cables

本文介绍了国内外交联聚乙烯 (XL PE)电力电缆绝缘在线监测技术的研究现状。讨论了 XL PE电力电缆绝缘在线监测技术所面临的一些技术问题。根据对交流叠加冲击电压下 XL PE绝缘放电特性的研究 ,探讨了 XL PE电力电缆绝缘在线监测技术的发展方向。

The status quo of the on-line monitoring technique for XLPE power cables at home and abroad is presented. Some problems arising from the on-line monitoring of XLPE power cables are discussed. The trend of development of the on-line monitoring techniuqe for XLPE power cables is predicted based on our study on the discharge characteristics of XLPE power cables under ac voltages superimposed by impulse voltages.
