Abstract
The invention provides an induction coil used for passive detection underground 0m-3m, which is manufactured by the following steps: on the same plane, closely winding the wire from the inside out; every preset turns of wire is wound, testing basic parameters of the wound wire by using a multimeter, wherein the basic parameters comprise an inductance, a Q value and a capacitance; when the variation of the inductance, Q value and capacitance is smaller than the preset threshold, regarding the current wound coil as the optimal wound coil, wherein the induction coil is packed in a fixed plastic sealed disc, the starting end and the final end of the induction coil are both used as leads, and the insulating layers 10+ / -2mm on the starting end and the final end are peeled off to expose the core.The induction coil provided by the invention is wound by a plurality of wires, having high electromagnetic conversion rate, and obviously improved induction distance as well as sensitivity.
Description
technical field [0001] The invention relates to the field of wire materials, in particular to an induction coil used for underground passive detection of 0m-3m. Background technique [0002] With the advancement of science and technology, the exploitation and utilization of underground resources is also increasing. However, in view of the unknown underground conditions and the lack of uniform and accurate distribution drawings of underground pipelines when laying natural gas and other pipelines underground, it has caused the current underground Circumstances that may lead to accidents when resources are exploited and utilized. [0003] The induction coil is a device that uses the principle of electromagnetic induction for coupling. There is a coil at the reader-writer and the transponder. The reader-writer connects the sinusoidal signal to generate an electromagnetic signal, and the induction coil of the transponder receives the electromagnetic signal of the reader-writer t...
