摘要
本项目研究发现通过向接地网注入电流,测量地表磁场并进行微分运算,能够对接地网的导体支路进行准确定位,因此提出了基于磁场微分法的隐性导体定位方法,这就需要对接地网地表的磁场进行精确测量.基于变电站特殊的电磁环境,本项目开发磁场测量装置,以满足接地网检测的实际工程需要.
This project found that by injecting current into the grounding grid,measuring the surface magnetic field and performing differential operation,the conductor branch of the grounding grid can be accurately located.Therefore,a hidden conductor positioning method based on magnetic field differentiation method is proposed.An accurate measurement of the magnetic field of the grounding grid surface is required.Based on the special electromagnetic environment of the substation,the project develops a magnetic field measuring device to meet the actual engineering needs of the grounding grid detection.
