Problems solved by technology

The magnetic permeability of the iron core limits the saturation magnetic flux of the iron core. A fixed iron core can only limit a fixed saturation magnetic flux, which is not universal.

Embodiment Construction

[0025] see figure 1 , the transformer magnetic core of the present invention comprises:

[0026] The annular magnetic core has a wide part 1 with a square cross section and a thin part 2 with a circular cross section, the wide part 1 and the detailed part 2 are integrally formed, and are made of the same magnetic core material;

[0027] Magnetic sleeve 3, the cross section of the magnetic sleeve 3 is a hollow square, the hollow shape is circular and matches the cross section of the detail 2, and the magnetic sleeve 3 is set on the detail; The magnetic sleeve is made of the same material as the annular magnetic core

[0028] The length of the wide part 1 is greater than the length of the thin part 2 . The output coil 4 and the input coil 5 are respectively wound on the wide part 1 ; the thin part 2 separates the output coil 4 and the input coil 5 .

[0029] see figure 2 , the centers of the wide part 1 and the detailed part 2 coincide, see image 3 , the middle of the mag...

The transformer magnetic core comprises an annular magnetic core and magnetic sleeves, wherein the annular magnetic core is provided with a wide part and slim parts, the cross section of the wide part is in a square shape, the cross section of each slim part is a round shape, the wide part and the slim parts are integrated formed and are same magnetic core materials, the cross sections of the magnetic sleeves are hollow square shapes, the hollow shapes are round shapes and are matched with the cross sections of the slim parts, the magnetic sleeves are sleeved on the slim parts, and the length of the wide part is larger than the lengths of the slim parts.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer magnetic core capable of adjusting saturation magnetic flux and a transformer thereof. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] When an alternating current flows through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil. The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondar...
