Pole Mounted Transformer Key Craft
1. Magnetic circuit design
The iron core's shape, size, hysteresis, and eddy current loss are important factors to consider. Properly designing the magnetic circuit can lead to efficient energy transmission and reduced loss.
2. Winding design
Factors such as the number of turns, wire material, interlayer insulation, and wiring method should be taken into consideration during the design process. By implementing a well-planned winding design, the transformer can achieve greater load capacity and reliability.
3. Insulation material selection
Choosing the right insulation materials is paramount to ensure safety and longevity. It's essential to opt for insulating materials that offer excellent insulation performance, high-temperature resistance, arc breakdown resistance, and moisture resistance.
4. Vacuum oil filling
Single-phase pole-mounted transformers typically utilize a vacuum oil filling method. This involves treating the transformer chips with a vacuum, injecting insulating oil, eliminating air bubbles, and sealing the transformers. The vacuum oiling process is beneficial as it enhances the insulation performance and thermal stability of the transformer, leading to prolonged service life.
5. Heat treatment
Transformers' mechanical properties and strength can be enhanced through heat treatment. This process alters the material's organizational structure, boosting its hardness and wear resistance while reducing stress and deformation.
