摘要
27.5kV交联聚乙烯单芯电力电缆在我国高铁牵引供电系统中应用广泛。目前27.5kV高压电缆及附件故障率比较高,难以对电缆缺陷和故障准确定位以及实时监测,影响到牵引供电设施的安全运行。通过研究运用物联网技术、地理信息系统(GIS)技术、空间索引技术等信息技术,对电缆信息有效、实时、自动化的采集,采用数字化运维和智能化监控手段,实现对电缆全路径在线监测、故障判断和精准定位。
27.5kV XLPE single core power cable is widely used in high-speed railway traction power supply system in China.At present,the fault rate of 27.5kV high-voltage cable and accessories is relatively high,so it is difficult to accurately locate and real-time monitor the cable de⁃fects and faults,which affects the safe operation of traction power supply facilities.Through the research and application of IoT,GIS tech⁃nology,spatial index technology and other information technology,the effective,real-time and automatic collection of cable information,and the use of digital operation and maintenance and intelligent monitoring means,the cable full path online monitoring,fault judgment and accurate positioning are realized.
