Problems solved by technology

The main technical problems are: 1. Since this winding rearrangement on-load switch can only adjust the capacity of the transformer, it is not suitable for transformers that can adjust the output voltage without interrupting the load due to large grid voltage fluctuations; 2. If it is necessary to adjust the output voltage of the transformer when it is excited, an on-load tap changer is required. Therefore, not only the cost of the transformer is increased, the volume is large, but the structure is also complicated.
