电缆顶管的定位探测与数据管理

在电缆线路中，由于没有掌握准确的地下电缆定位数据，致使市政建筑施工中容易发生损坏电缆的事故。为此，提出采用示踪频率电磁法对地下电缆进行定位探测，并利用信息技术对电缆数据进行计算机可视化管理。从磁性分布的角度分析了示踪频率电磁法的探测原理，通过分析电性分布说明了此方法有较高的探测精度，并介绍了具体的探测操作方法和实现电缆数据信息化管理的流程。该方法在深圳供电局110kV民超线中应用，效果良好。

Positioning and Data Management of Top Cable Conduits

Underground cables are often damaged in public facility construction due to the lack of accurate cable positioning data. Therefore, the use of tracking frequency electromagnetic method and information technology is suggested for underground cable position detection and computer-based visualized management of cable data. The detecting principle of the tracking frequency electromagnetic method is analyzed from the angle of magnetic distribution, and the high detecting precision of the method is shown by electric distribution analysis. The specific detecting method and the informatization management process of cable data are described. The proposed method has been applied to 110 kV Minchao Line under Shenzhen Power Supply Bureau with good effects.
