Problems solved by technology

Due to the material change, using the original setback repair method will cause the U-shaped iron core to be delaminated and chipped due to being too thin, and the performance will be changed. Therefore, the setback repair method is not suitable for U-shaped iron core transformers made of thin silicon steel strips. Inductance adjustment
At the same time, because the U-shaped silicon steel strip iron core has fixed dimensions, fixed layers, tight press-fitting, and the thickness of the silicon steel is too thin, it is impossible to adjust the inductance by peeling off a certain number of layers of silicon steel strips.
Since the structure of the transformer is two halves of the U-shaped iron core butt-stacked, there are differences in its position, size, and shape of the transformer coil, so it is impossible to accurately calculate the cutting amount of the U-shaped iron core, so it is impossible to use the cutting method to adjust the inductance.

Embodiment

[0021] Some kind of aviation ignition transformer, its iron core is made of U-shaped iron core pressed by multiple thin silicon steel strips with a thickness of 0.08mm, and the inductance of the transformer after assembly is required to be 300±20μH. The specific installation The adjustment method is as follows:

[0022] 1) Preparation: Prepare qualified coil components, U-shaped iron cores and parallel clips, and use silk cloth to dip anhydrous ethanol to clean the 2 end faces of the U-shaped iron core to ensure that they are clean and free of impurities.

[0023] 2) Assembly: Insert one end of the two U-shaped iron cores into the center hole of the skeleton of the coil component, and then put them into the parallel clamp as a whole, align the end faces of the iron cores, and tighten the parallel clamp screws to ensure that the two halves of the iron cores are docked neatly;

[0024] 3) Measurement: Set up the LCR measuring instrument, and set the test conditions as 1kHz, 1.0V...

Abstract

The invention relates to a method for adjusting transformer inductance of an aviation ignition device. The inductance of the transformer is adjusted by adjusting the gap between two halves of U-shaped iron cores. Because the present invention avoids the shortcomings of the original method through the bonding method, the inductance of the transformer can be adjusted effectively and conveniently, and the reliability of the aviation ignition device is guaranteed.

Description

technical field [0001] The invention relates to an inductance adjustment method, in particular to a transformer inductance adjustment method of an aviation ignition device, which realizes convenient adjustment of the transformer inductance of a U-shaped iron core. Background technique [0002] The existing transformer adjustment method is to set back the magnetic poles in the middle of the magnetic cores, and change the gap between the two magnetic cores, thereby changing the inductance of the transformer. At present, in the aviation field, the magnetic core material of the transformer of the aviation ignition device is changed from ferrite to a U-shaped iron core formed by pressing multiple thin silicon steel strips with a thickness of 0.08mm. Due to the material change, using the original setback repair method will cause the U-shaped iron core to delaminate due to being too thin, generate debris, and change performance. Therefore, the setback repair method is not suitable ...
