摘要

电力电缆是电力系统中的重要设备，电缆的运行状态关系到输配电系统的安全可靠运行。电缆状态检测技术指根据电缆运行状态的历史数据，综合运用停电试验、带电检测、在线监测等技术对电缆状态量进行智能感知，为电缆运行性能综合评估提供关键参考信息。文中综述了近年关于电缆状态感知及检测技术的国内外研究现状，分别从温度、载流量、局部放电、受潮、应变/振动和接地电流等状态量进行评述，阐明了不同状态量的检测原理，介绍了目前电缆状态检测技术研究及实践中的应用情况和发展水平，并探讨电缆状态检测技术的主要发展趋势。

Abstract

Power cable is an important equipment in power systems and its operation conditions are related to safe and reliable operation of transmission and distribution system. The condition detection technology of cable refers to intelligent perception of cable in accordance with the historical data of operation conditions of cable and comprehensive application of such technologies as power off test

live test and online monitoring detection so to provide key reference information for the comprehensive assessment of operating performance of cable. In this paper

the research status of condition sensing and detection technology of cable at home and abroad in recent years are reviewed

such conditions as temperature

ampacity

partial discharge

moisture

strain/vibration and earth current are described respectively and the detection principles of different conditions are explained

the application and development level of condition detection technology of cable in research and practice are described and the main development trend of cable condition detection technology are discussed.
