TRIDIMENSIONAL WOUND CORE TRANSFORMER MACHINES

Description
 Tridimensional wound core (3D) transformer is a new designed high performance transformer. It creatively reformed laminated magnetic structure of power transformers and three-phase layout, more optimized product performance, such as three-phase magnetic circuit is completely symmetrical, energy-saving effect is remarkable, greatly reduced noise, stronger overload, compact structure and small volume, etc.

3D Wound Core Structure 

  • 3D wound core - Continuously wound 1-piece core ring assembled using automatic winding machine (negligible number of joints and air gaps present results in low stray magnetic loss). 3 identical core rings are combined to make a 3 phase core.

  • 3D wound core – Each core ring limb resembles a semi-circle allowing 2 core ring limbs of equal cross section to combine to make a core limb. Cross section of core limbs takes closer shape of a circle, with a higher filling factor of approx. 98% resulting in magnetic flux being almost fully utilized.

  • 3D wound core - The different magnetic path directions of both core ring limbs that make a core limb combine to achieve zero vector sum for the magnetic flux, resulting in magnetic flux being balanced in each phase. Magnetic path of 3 phases are of equal distance, resulting in 3 phases having better balanced magnetic circuits and reduced exciting currents


Characteristics of the 3D wound core transformer

  • Balanced magnetic circuits and exciting current in all 3 phases

  • Lower no-load losses

  • Reduced vibrations

  • Reduced in-rush currents

  • Better short circuit withstanding capability

  • Reduced exciting (a.k.a. reactive or no-load) currents

  • Compact structure, low operating sound levels
