Orthogonal Coil in the Path Detection of Buried Cable

介绍了一种正交线圈应用到基于电磁法的地埋电缆路径探测设备接收器的设计。通过判断两个线圈感应电动势的大小和比值关系即可判断出待测电缆的位置信息,从而确定电缆路径。通过理论计算和comsol多物理场软件仿真的方式对正交线圈在地埋电缆路径探测中的应用进行了详细描述。

This paper introduces the design of orthogonal coil which is applied to a receiver of buried cable path detection equipment based on the electromagnetic method.The location of the buried cable can be tested and found by judging the relationship between the size and ratio of the induced electromotive force of two coils,as a result,the path of the buried cable can be detected correctly.The paper makes a detailed description about the application of orthogonal coils in the path detection of buried cables from two aspects,which include theoretical calculation and comsol multi-physics field software simulation.
