Device for rapidly testing amorphous magnetic ring and test method thereof

Abstract

The invention discloses a device for rapidly testing an amorphous magnetic ring and a test method thereof, and relate to the technical field of magnetic ring test devices and methods. The structure of the device comprises a plurality of single-frequency inductance test instruments, an upper die and a lower die, wherein the upper die is provided with a plurality of conductive probes; the lower die is provided with conductive sheets; each single-frequency inductance test instrument comprises two test lines; one test line is connected with one conductive probe; the other test line is connected with one conductive sheet corresponding to the position of the conductive probe. According to the device and the method disclosed by the invention, when the inductance of the amorphous magnetic ring under a plurality of frequencies, an expensive test instrument does not need to be bought, and the test can be realized by virtue of an old existing test instrument, thus the cost can be greatly reduced; because the plurality of conductive sheets are arranged in parallel, the device can be immediately pushed to another test station to test the inductance of the second frequency after the inductance under one frequency is tested, and the inductances of other amorphous magnetic rings under other frequencies can also be tested simultaneously, thus the test efficiency can be greatly increased compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of magnetic ring testing equipment, in particular to a device for quickly testing an amorphous magnetic ring and a testing method thereof. Background technique [0002] Amorphous magnetic ring is a magnetic element processed by amorphous material, which can be used as main transformer, control transformer, filter inductor, energy storage inductor and reactance of large, medium and small power in various forms of high frequency (20KHz-100KHz) switching power supply Cores for transformers, magnetic amplifiers, saturable reactors, EMC filter common mode inductors and differential mode inductors, ISDN miniature isolation transformer cores; at the same time, they are widely used in various types of transformer cores with different precision. [0003] In different use environments, amorphous magnetic rings have inductance requirements for only one frequency and multiple inductance requirements for different frequ...

Problems solved by technology

[0004] Old-fashioned testing instruments generally can only test the inductance of one frequency (called single-frequency inductance testing equipment). When it is necessary to test multiple inductances of different frequencies, it needs to be tested many times to complete. On the production line, it is generally a Workers are responsible for testing the inductance of a frequency, and the qualified amorphous magnetic ring flows to the next worker, and the flow-through test is carried out in turn, which requires multiple workers, resulting in high labor costs; and if only one worker is used for multiple times Generally, the worker conducts the first test on a certain number of amorphous magnetic rings, puts them aside after the test, and then conducts the second test after all the measurements are completed, which takes up the space in the inventory. Increased inventory costs
