1. Traditional 3-phase Reactor

    1.1 The Theory of Traditional 3-phase Reactor

 blob.png    blob.pngblob.png

     Design descriptions:

    Upper and lower iron yoke

   Assembled in the core, with top and bottom iron yoke of a magnetic core, material for the silicon steel sheet in general

    Three lines of the phase inductance

 

    1.2 The disadvantage of existing technology

  1. 1) Core generally use silicon steel sheet (generally within 0.5 mm thickness), laminated difficulties;Core air gap, and wide edge magnetic flux.

  2. 2) Iron core and installation lines into a line, so the magnetic circuit between the different line package, inductance is difficult to balance, are generally more than 3%, affect the product use.

 2.1 Design and Assembly:   

1Upper and lower core: the Mn - such as zinc ferrite or silicon steel sheet or amorphous material design, similar in shape to triangle.

2Column in the core: the Mn - zinc ferrite or alloy magnetic powder core (iron silicon aluminum, iron, silicon, high flux, etc.) design, can be a circular or other shapes, cooperate with the upper and lower core composed of a set of three-phase iron core is used.

3Coil: can use copper wire or aluminium wire winding, every phase in a coil.

4Insulation board: the insulation design, can be used to isolate the coil and iron core, at the same time, the column core in fixed position.

5Screw/nut: adopt better strength metal materials (such as iron, stainless steel, etc.).Mainly used for fixed products.

6Install base: can be made of material such as stainless steel or aluminum with positioning screw, make the products such as screws fixation.Fixed hole between the two lines into a triangular structure.

 

     2.2 The advantage of Improved 3-phase Balance Inductor

a. The difference between each phase inductance is small, high inductance balance.

b. High reliability, convenient and concise
