Winding power transformers is a process that requires professional knowledge and skills. The following are the basic steps and precautions:
Basic steps:
1. Open the boring and dismantle the old line, and remove any remaining insulation paper.
2. Insert insulation paper into the stator slot.
3. Wrap the coil according to the span of the original magnetic pole coil.
4. Insert wires into the stator slots and insert insulation paper and slot wedges into the slots.
5. Connect the coil wires of each magnetic pole and the lead wires.
6. Insert insulation paper between the different phase windings at both ends of the stator, shape the windings at both ends, and tie them with a white cloth flat tape.
7. Heat and bake (60 ° C), coat with insulation paint, and then heat and bake (80 ° C) for one hour before removing.
8. After assembly, use an instrument to measure the three-phase line resistance and insulation condition.
9. Conduct a power on test run.
Notes:
During the winding process, it is important to pay attention to insulation issues to prevent short circuits or electric shocks.
2. The size and appearance of the winding should comply with regulations, ensuring that the coils are arranged neatly without crossing or overlapping.
3. Pay attention to the tightness of the winding. Over tightening may cause deformation of the coil, while over loosening may affect the performance of the transformer.
4. Check the correctness of the coil, including specifications, sequence, and phase, to ensure compliance with design requirements.
5. Use appropriate insulation materials and operate according to the specified insulation level.
6. After the winding is completed, markings should be made for tracking and confirming responsibility.
Please note that the above are only basic steps and precautions. In actual operation, appropriate adjustments may need to be made based on specific transformer models, specifications, and winding requirements. Therefore, it is recommended that electricians or technicians with professional knowledge and skills operate the winding of power transformers to ensure the quality and safety of the winding.
