Iron core matching method based on electromagnetic induction effect

Abstract

The invention belongs to the technology of electron device detection, and relates to an iron core matching method based on electromagnetic induction effect, wherein the iron core matching method is used in symmetrical products with the same parameters. The matching method comprises the following steps: (1) two groups of wires sequentially penetrate through a group of iron cores to be matched; (2) two output ends of an audio power supply are connected at two input ends of a power source transformer, and then one output end of the power source transformer is connected with a group of wires penetrating through the iron cores to be matched, the other ends of the group of wires are connected with a middle end of a slide rheostat and an X end of an oscilloscope, the other output end of the power source transformer is connected with one end of the slide rheostat, and meanwhile the end of the slide rheostat is connected with one ends of the other group of wires and a grounding end of the oscilloscope, and the other ends of the other groups of wires are connected with a Y end of the oscilloscope; and (3) a plurality of wave forms of the iron cores to be matched are sequentially displayed on the oscilloscope, and an iron core with the proximal wave form among the plurality of wave forms is matched and used.

Description

technical field [0001] The invention belongs to the detection technology of electronic devices, and relates to an iron core matching method based on electromagnetic induction effect with the same parameters used in symmetrical products. Background technique [0002] At present, it is widely used in the matching of iron cores in symmetrical magnetic products in electronic products. It is to measure the parameters of a single iron core separately, and then compare the parameters of each iron core separately. This kind of matching method is labor-intensive. , Time-consuming, and prone to inaccurate matching, so that the produced magnetic amplifier cannot meet the design technical requirements, which not only affects the assembly quality and production progress, but also affects the complete solution of other technical problems due to unclear judgment. Contents of the invention [0003] The purpose of the present invention is to propose a time-saving, labor-saving and accurate...
