XLPE电缆金属护套环流在线监测系统

摘要

XLPE cable has been widely applied in the grid because of its good electrical properties. Its insulation state directly relates to the safe and reliable operation of power system, how to effectively monitor the insulation state of XLPE cables is very important for power system. In order to meet the needs of power system, XLPE cables metal sheath circulation current on-line monitoring system is designed based on LabVIEW and described the hardware and software designed methods in this paper.%XLPE电缆由于其良好的电气性能在电网中得到了广泛地应用,XLPE电缆的绝缘状况直接影响到电力系统的安全和稳定,如何有效地监测XLPE电缆的绝缘状态对电力系统的安全稳定运行意义重大.为了满足电力系统的需要,有效地监测电缆绝缘状况,以LabVIEW图形可视化编程软件作为开发工具,设计了XLPE电缆金属护套环流在线监测系统,以此监测电缆的绝缘状况,文中阐述了监测系统的硬件组成和软件设计方法.
