摘要
随着城市化进程的逐步深入,电力电缆入地率越来越高。针对地下电力电缆本体的运行状态监测越来越重要的现状,提出了一种新型隧道电缆护层接地环流在线监测系统及方法,主要由综合监控、电流互感器、电流采集装置、高防护等级外壳构成。电缆护层环流实时监测系统采用先进的软硬件设计理念,充分考虑了隧道内的应用环境和可靠性要求,实现高防护等级、高集成度、高EMC性能的一体化电缆护层环流实时监测系统,具有很好的推广应用价值。
With the acceleration development of urbanization process, the rate of power cable underground is higher. In view of the fact that the monitoring of the underground power cable is becoming more and more important, a new on-line monitoring system and method for the ground circulation of the tunnel cable sheath is proposed. It mainly consists of comprehensive mon- itoring, current transformer, current acquisition device and shell with high protection level. Cable sheath circulation real-time monitoring system use the advanced software and hardware design, the design has realized the cable sheath real-time monitoring of circulation, give full consideration to the application environment of the tunnel and reliability requirements, high protection grade, high integration, high EMC performance of the integrated cable sheath circulation, real-time monitoring system for cable tunnel grounding circulation of on-line monitoring has great value in popularization and application.
