为了更好地研究海底光缆维修过程中的探测定位问题,提出了将具有高探测精度的超导量子磁力仪应用到海底光缆工程领域的设想,并利用泊松公式对海底光缆磁场数学模型进行研究,分析了不同探测距离的磁场变化特征和磁强度大小,设计了超导量子磁力仪探测海底光缆的野外实验。对比分析表明:利用超导量子磁力仪能够较好地探测识别海底光缆位置,探测结果和仿真分析的磁强度变化趋势相一致,磁强度大小接近,探测结果和以往的工程实践相符合。超导量子技术较现有的海底光缆探测设备技术更新,探测精度更高。

In order to improve the technical level of submarine cable detection and location,the superconducting quantum magnetometer with high detection accuracy is proposed to apply to the field of submarine cable project,and mathematical models of submarine cable are established by Poisson equation.The change in magnetic field characteristics and magnetic intensity of different detection range is calculated,and a field experiment of superconducting quantum magnetometer to detect submarine cable is designed.The result shows the superconducting quantum magnetometer can detect and identify the location of submarine cable;the detection results and simulation analysis results of changing tendency of magnetic intensity are consistent;the detection results and past engineering practices are consistent;the detection precision of superconducting quantam magnetomer is higher than that of existing cable detection equipment.
