Dry-type transformers are one of the important transformer equipment in the power system. Therefore, in the manufacturing process, the production process is demanded extremely.
1. For the transformer short-circuit withstand capacity, the axial compression and radial support can achieve the effective support of penetration. Specific requirements are: the core and the low-voltage winding, the low-voltage winding and the high-voltage winding form a solid hard fixation; high and low voltage winding maintain the contour.
2. Should pay attention to The core of the stacking and assembly: clamp, pad and yoke assembly position control, cylinder block and insulation pad need to match.
3. To ensure and control the quality of laminated insulation and insulation pads, coating method, hot pressing strength have been strictly controlled, received good results.
In addition, consider the impact of product performance and reliability of the various manufacturing factors, according to product structure and size of the relative relationship. Thereby improving the overall quality of dry-type transformers manufacturing.
