摘要
电力电缆的可靠性在很大程度上取决于其绝缘性能。充油电缆的在线监测技术可对电缆的可靠性随时做出判断,从而能及时发现潜伏的故障,必要时可提供预警。本文对高压充油电缆各项在线监测技术进行了系统的研究,在介绍各项技术的同时详细讨论了技术的关键点及难点。同时针对在线监测的技术需求研制开发了从软件到硬件的各类产品,设计建设了较为成熟的高压电缆在线监测系统。
The reliability of power cables depends to a large extent on their insulation proper ties.The online monitoring technology of oil-filled cables can judge the reliability of the cables at any time,so that potential failures can be found in time,and early warning can be provided if necessary.This paper systematically researches on-line monitoring technologies for high-pressure oil-filled cables.The key points and difficulties of the technologies are discussed in detail while introducing the technologies.At the same time,according to the technical requirements of online monitoring,various products from software to hardware have been developed,and a more mature online monitoring system for high-voltage cables has been designed and constructed.
