1.For 10kV-level products, their moderate voltage level allows for convenient insulation structure handling. Typically, these transformers are designed with a traditional dual-winding dual-split structure. Two sets of low-voltage coils are axially split, and two sets of high-voltage coils are axially arranged. During casting, the two sets of coils are cast as one coil, and electrically, the two sets of coils are connected in parallel.
2.For 35kV-level products, the relatively higher voltage requires special structural treatment of the low-voltage coils to ensure good electrical performance, including features like partial discharge capacity and lightning impact resistance. After treating the low-voltage coils in the design process, the number of sections and layers of the high-voltage coils is reduced, maintaining a uniform electric field distribution within the coil.
3.In addition to these distinctions, the operational design steps for photovoltaic power transformers include: first, optimizing the photovoltaic power generation design, thoroughly understanding the site's basic characteristics, and refining the design proposal. Second, strengthening photovoltaic power generation infrastructure management, rigorously controlling qualification reviews, and standardizing the quality of photovoltaic power generation processes. Third, exercising strict control over photovoltaic power generation equipment to avoid the use of substandard equipment and products.
