A3120SL TRANSFORMERS KITS TRAINERS TRAINERS SLIDES Following are the descriptions of 16 slides taken to show the steps necessary to build a transformer. While showing them prior to practical activities the instructor, by pointing out actual construction details and procedures, can offer comments and suggestions thus improving considerably his teaching effectiveness in a very productive manner since he can address large groups of students simultaneously. SLIDES 1. Shown are the components of a single phase transformer (on the left) and a three phase transformer (on the right). Not shown is the copper wire which is not part of the kits. It can be noted that the bobbins are slotted and therefore do not require drilling of the holes for the wire. 2. The bobbin is mounted on the winding machine (a typical production machine is shown here) and the copper wire is threaded through the first bobbin slot. 3. The end of the copper wire is secured to the winding shaft. On other types of winding machines it may be more convenient to stop it with some adhesive tape. 4. The required number of turns is wound. 5. The last turns are secured with some adhesive tape. Note that the ends of the windings are insulated and identified with the colored tubing.
6. Mylar tape is wound around the first winding. 7. The copper wire is cut leaving a good length of it. 8. Final insulation is wound around the last winding. 9. All windings have been completed on this bobbin. 10. The first laminated iron "E" sheet is inserted. 11. Insertion of laminated iron "E" sheets continues. The sheets must be inserted with the same orientation in regard to the cut edge burr. If not, air gaps will result within the lamination thus decreasing the transformer efficiency. 12. Laminated "E" sheets have all been inserted. Now the "I" sheets are inserted at the end of the "E" sheets. 13. Same as above, at the other end of the "E" sheets 14. The frame is mounted. It has to be ensured that the mounting rods do not touch the laminated iron. 15. The snap-on terminals are mounted on the frame rail. 16. The windings ends are soldered to the terminals.
